Cutting through the confusion of large displays

To achieve a large image, installers have a myriad of options.

Should they go projection?

This is, by far, the most cost effective and simplest way to attain a large display image, especially if high resolution is required. But is there too much ambient light? Would a high brightness laser projector cut through this?

Should they install a Large Format Display (LFD)?

For a large image a single LFD screen is heavy, cumbersome and expensive.  They could create a videowall with multiple LCD screens but this has the downside of bezel frames around each screen slicing through the overall image.

Or they could look at an LED display. 

LED displays are made up of slim LED panels installed flush beside each other to create a seamless display with no bezels disrupting the image. They are expensive compared to projection but large LED displays are becoming far more comparable in cost to similar size LFD videowalls.

But which one is best?  We catch up with Ross Noonan, Technical Product Specialist at Optoma, to try to cut through the confusion. 

Q: So, which solution is best Ross?

A: It depends on the environmental factors.. In a high ambient brightness environment, projection will look washed out but if the ambient light is not too high or light could be controlled, projection may be the best (and certainly the cheapest) option. 

If the ambient light is high and you want large seamless imagery without bezels interrupting the image, you may need to look at installing an LED display. 

Q: That sounds complicated.

A: It doesn’t need to be.  You need to ask more questions perhaps than for a regular projected display but honing down the requirements, by asking a number of key questions, will help you choose the right solution.

Q: What questions do I need to ask when looking at LED displays?

A: Do you need a permanently installed or mobile solution?

Is it for indoor or outdoor use?

How bright is the environment where it will be operating?

What size and aspect ratio do you need?

What content will you be showing?

Where will the audience be in relation to the display?

How accessible will the display be if it needs maintenance?

Q: Can you use LED displays in full sunshine?

A: Yes you can.  Brightness of LED panels is measured in Nits.  A single Nit emits over three times more light than a single lumen.  LED panels can be scheduled to change the brightness at different times of day. 

Q: As the LED display is made of lots of tiles, there must be more flexibility in size and aspect ratio. Right?

A: Size and aspect ratio is a little bit more complex for LED displays than projection.  Due to their modular setup, there is no limit to the overall image size for LED displays. True. But this is where it can be more complicated than projection.  When looking at the size and aspect ratio, you also need to consider your content and desired resolution.

The LED panels that make up an LED display are a certain aspect ratio.  If the same number of LED panels are used horizontally and vertically – it will retain that same aspect ratio.  For example, Optoma LED panels are 16:9 aspect ratio.  A display of 10x10 panels would keep the aspect ratio the same.  But if the customer wanted a specific width and height, the aspect ratio may not be 16:9 and it would alter the resolution – as there would be more or less pixels depending on the size chosen.

Resolution is determined by the size and the pixel pitch of the LED display – that is, the distance between each LED diode/pixel in the panel.  The narrower the pixel pitch, the greater the resolution of this panel. 

Pixel matching the content to the native display resolution is always the best option. But if the content resolution varies or cannot be known up front, Optoma has a range of image scalers which use the exceptional HQView technology to give the best on-screen results.

So, if people want a definite size, they may need to compromise on the resolution and aspect and/or create content at that resolution.  Optoma has simplified this for customers by offering a range of panels at specific sizes and resolutions.

8 x 4.5m (361”)

10 x 5.6m (452”)

Customers can have custom sizes with different resolutions but they should try to ensure the overall display’s aspect ratio is consistent with its individual panels to ensure the image is not distorted.

Q: Why is it important to know where will the audience be?

A: The closer the audience is to the screen, the narrower the pixel pitch you need for them not to see individual pixels.  As a rule of thumb – for a 2.6 pixel pitch, the minimum viewing distance is 2.6m away, for a 2.0 pixel pitch it is 2m.  But this is not the optimal viewing distance.  We advise that the optimum distance if roughly the width of the display.  So the best place to view a 5m wide display is 5m back.

One more thing.  You also need to think about the viewing angle.  Better quality LEDs have a wider viewing angle. If your audience will be viewing the display far off-centre, you need to make sure the diodes have a wide viewing angle, which ours do.

Q: How accessible will the display be after install?

A: Some LED displays are only accessible from the rear which would need substantial framework, designed and signed-off by structural engineers. 

All of Optoma’s out of the box solutions are designed to be mounted directly onto the wall using wood screws and are front serviceable with no cabling required to connect each tile.  This makes installation and servicing quick and efficient.  They also have 3-axis adjustments to mitigate uneven walls. 

If one panel gets damaged, it can be simply swapped out without having to dismantle the entire display. It is easier and cheaper to change this single panel within an LED display than for a LFD or videowall. 

Every display comes with a custom tool kit with everything needed to install, as well as spare LED panels and components.  This includes a unique suction device for removing individual panels which significantly reduces the potential for damage during installation and servicing.

Q: Does it need much servicing then?

A: No. Optoma LED displays need minimal maintenance.  There are no filters to clean.  Fluctuations in temperature and damp may reduce the lifespan of diodes so we advise to leave the display on standby to keep these warm and dry.  If there is a build-up of dust on the front of the display, you can brush this gently with a soft brush - but other than that, they need very little maintenance.

Q: What are the main pitfalls for installers?

A: One of the common pitfalls is that buyers look for the cheapest option and buy directly from a far East supplier.  This is high risk as these companies request payment up front and, when there are problems, provide no local support.  I would recommend choosing a trusted and established AV brand within Europe with whom they can be assured they would have support during and post install.

We can guarantee a single bin pick for LEDs.  This means that the LED panels all come from the same production run to ensure a consistency in colour performance and brightness across the whole display. 

Q: Anything else?

A: Once the size and resolution is set, this will determine what controller you would need.  All Optoma displays come with a controller and all cabling. 

Each controller has a fixed number of outputs to prevent bandwidth issues.  Optoma MCTRL660 is designed for screens with a maximum resolution of 1080p.  It has four outputs dividing a 1080p screen into four signal runs.  A 4K resolution display would need a controller with 16 outputs – four times that of 1080p – so would use Optoma CTRL4K.  If you need full redundancy, you would need an extra controller and cabling.

The only other thing to consider is the power needed for the display.  This is dependent on size and brightness.  We advise customers on the maximum consumption based on maximum brightness so they can arrange for the electrics to accommodate this. 

Optoma has a range of ultra-thin, 16:9 native aspect ratio LED displays.  These are easy to install, operate and maintain, and engineered for reliability and superior image quality.

Is UHD really 4K?

Resolutions

With any new technology, the terminology can be baffling. And resolution terminology can be the most confusing of all!

Resolution is simply the number of pixels in an image. The higher the number of pixels, the greater the resolution and the better the image quality will be.

 

Resolutions are as follows:

  • UHD 4K (3840 x 2160) pixels
  • WUXGA (1920×1200) pixels
  • Full HD 1080p (1920 x 1080) pixels
  • WXGA / HD Ready (1280 x 800) pixels
  • XGA (1024 x 768) pixels

 

Optoma 4K Ultra High Definition (UHD) projectors provide four times as many pixels as Full HD 1080p. That’s 8.3 million on screen pixels (3840 x 2160) bringing greater realism to every scene with increased depth and light and shadow detail for a truly immersive experience.

The UHZ65, UHD60, UHD550X and UHD65 all use a 4M pixel chip.  The latter 4K UHD models - UHD40 and UD51 use a 2M pixel chip. But Optoma UHD 4K projectors do not pixel shift in the same way as the 3LCD ‘4K enhanced’ projectors from Epson and JVC.

To get your head around this, let me give a simple overview of how each technology works.

A projector using 3LCD technology splits the white light from its lamp into three colour beams and directs each to their own LCD panel to create the image to be projected.

At the heart of every Optoma projector is a DLP® chip. Developed by Texas Instruments, this chip has millions of microscopic mirrors, each measuring less than one-fifth the width of a human hair and each corresponding to one pixel on the final projected image. A spinning colour wheel made up of coloured segments is placed between the light source and the chip. The mirrors are then turned on and off perfectly in time with the right colour – allowing the projector to display a total of 16.7 million different colours for a fantastically vibrant, life-like picture. By using mirrors rather than LCD panels, DLP projectors are shown to have better pixel alignment and therefore show a sharper image.

DLP chip

Optoma’s 4K UHD projectors with over four million mirrors (UHD60, UHD65, UHZ65) deliver two discrete pixels for each mirror. UHD40 and UHD51 deliver four discrete pixels for each mirror.  The inherent fast switching speed of the DLP chip and Texas Instruments’ latest XPR™ technology allow the projectors to display the full 8.3M pixels to the screen from these pixel chips. This happens so fast that the eye blends them into one image.

The ‘4K-enhanced’ 3LCD projectors from Epson and JVC use native HD 1080p chips (1920x1080). To achieve ‘4K-enhanced’ they project a 1920x1080 image, then on the next refresh of the chips a second 1920x1080 image is off-shifted diagonally and overlaid onto the first. The total number of addressable pixels in this process is 2x (1920x1080) = 4.15 million - half of the 8.3 million in a native 4K signal.

The Consumer Technology Association (CTA) defines 4K UHD resolution as 3840 x 2160 or greater than 8 million addressable pixels. For projection systems, 4K and 4K UHD resolution should be defined by the on-screen counting of pixels or the ability to see greater than 8 million dots.

With the full 8.3 million on-screen pixels, Optoma’s 4K UHD projectors meet the Consumer Technology Association (CTA) requirements for 4K UHD and CTA High Dynamic Range (HDR) compatible display standards.

Among the smallest 4K projectors on the market, Optoma’s 4K UHD projectors set a new benchmark in performance.

 

The pros and cons of a projector over TV

A projector can give you amazing gaming experience and a true cinema-like feel at home – but what are the pros and cons of choosing one over a big screen TV?

Pros

Size This is a major reason to go projection! Actors on TV look larger than life. Hang on a second – they ARE larger than life. Filling your entire field of view creates a completely absorbing experience.

Viewing a standard TV of 37 inches from the average sofa distance of nine feet, your eyes just cannot see all the detail in a 1080p image. Blow that up four times to 100 inches and you can see each strand of hair, every blade of grass. And this is where the benefit of 4K comes into play. A larger image benefits greatly from the added resolution. At that distance most people will see pixels on a 150-inch 1080p image, but not with 4K.

As seen on the graph below, at nine feet from the screen anything bigger than a 65” image will look better with 4K. Optoma projectors can produce images up to 300 inches.

 

 

Easier on the eyes You may think having such a large screen may hurt your eyes. Actually, it's the opposite. Filling a larger percentage of your visual field, and with less overall brightness, a big screen is actually more comfortable to watch and, just like in the cinema, the picture is also more immersive.

Space and setup Projectors can be used anywhere there is a power source, a flat surface and enough space. They are light and portable to be taken around to a friend’s house for a gaming session or an outdoor film night. A TV is less flexible to pop under your arm and take to your mates!

 Projectors can be ceiling mounted or simply placed on a table or shelf – and you don’t have to have a screen. You can project straight onto a plain wall. If you do want a screen - these come in all shapes and sizes. They can hang on the wall or be retractable, where the screen disappears into the ceiling or you can get a portable one that you simply pull up.

Short throw and ultra short projectors are ideal for gamers as these create a large image from very close to the screen or wall. Gamers are therefore behind the projector ensuring no shadows are cast across the image.

Cost

Projectors are, on the whole, cheaper than comparably sized Full HD TVs. Getting a TV larger than 100 inches currently costs around £30,000 (if you can find one to buy). Getting the same screen size and equivalent picture quality could cost as little as £500 with a projector.

Audio

Most home projectors have a built-in speaker – perfect to plug and play. And if you want to connect to an external sound system, you can with the audio output. 

Wireless connectivity

Optoma projectors can also work wirelessly up to HD quality using the optional WHD200.

 

Cons

Light

Light can be a problem if the screen or wall is subject to direct sunlight. But Optoma’s bright home entertainment projectors are designed to be used with the lights on. And the darker the room, the more vibrant the image will be. 

Lamps

Nearly all home projectors are lamp-based. Like any lamp-based light, these will eventually need replacing. How often will depend on how much use the projector has had and putting the lamp in Eco mode will greatly increase the lifespan of the light source from 5,000 to 8,000 hours*. Based on a 20 hours a week that equates to around 5-8 year’s use. 

Expectations

After getting a projector all your friends' TVs will seem unbearably small.

 

Upsize that tiny TV; go projection!

Dust is everywhere

All electronic products are exposed to airborne dust throughout their lifetime.

This is not generally a problem for most consumer products but for professional applications, such as museums or attractions, where projectors need to operate around the clock, the build-up of dust particles can potentially compromise the quality of the image projected, affect the overall performance of a projector and shorten its lifetime.

 

Dust-sealed filter-free design

Optoma’s ProScene laser projectors are precision engineered with a unique optical dust-sealed, filter-free design that prevents dust and dirt affecting the system. The projectors need very little maintenance as there are no filters to remove and clean, therefore minimising downtime for the venue.  In addition, Optoma’s ProScene DuraCore laser line-up all come with an IPXX independent dust resistant certification.

 

What is an IPXX certification

An IP rating stands for ingress protection and basically states how well the equipment is protected from dust or liquids.  The IP code, published by the International Electrotechnical Commission, rates the degree of protection given by the electrical equipment casings against dust or water. The standard provides consumers with more detailed information than vague marketing terms such as ‘dustproof or waterproof’. Independent Ingress Protection tests are conducted in accordance with IEC 60529.

 Optoma ProScene ZU850 laser projector

ZU850 gets top marks for dust resistance

We recently sent our 8,200-lumen ZU850 laser phosphor ProScene projector to an independent IP test lab. The researchers placed the projector in a dust chamber and exposed the unit to airborne circulating dust for 8 hours at 25 °C ± 10 °C.

On completion of the test the black unit was caked white with dust but was found to be dust tight with no dust passing through the airtight optical engine and functional operation unaffected.

The ZU850 was awarded the highest classification of IP6X – which offers a completely dust free protection for the device.

 

 

Brilliant benefits with optoma warranties

When buying a projector, people rightly focus on the spec of the projector and choose a model that is suitable for how and where it will be used, the brightness of the room etc.  If you haven’t bought your projector yet and would like a few tips, take a look at our earlier blog: Choosing the right projector

But did you check the details of the warranty? Yawn. Boring? Not at all!  There are some brilliant benefits that come with the standard warranty from Optoma.  


All Optoma projectors are designed for continuous 24/7 operation. We are one of the only brands in the industry to offer this across our entire range.

5-year colour guarantee
We are so confident that your image colour quality will remain as good as on the day you bought it that we guarantee it for five years.  FIVE YEARS!

Oops - cut the power – no worries
Most Optoma projectors have ‘Direct Power Off’. Cutting power to these projectors suddenly will not damage or shorten the lamp/laser or projector lifetime and will not affect the warranty. Phew.  

Lamp warranty
Our standard warranty for ProScene models includes a 12 month lamp guarantee. This is included free of charge with no additional cost.

Non-standard installation
Projectors are usually installed horizontal to the floor - either ceiling mounted or placed on the desktop. But some installations need the projector to be turned on its side to create a portrait image or point straight down to the floor/up to the ceiling. Many of our professional projectors support these orientations, known as 360 degree and portrait mode. These projectors can be used in non-standard orientations without invalidating the warranty.

Bespoke warranties for professional installations
We can tailor warranties on our ProScene models to meet specific needs including support, preventative maintenance, extended warranties, swap units, de-install/re-install warranties.

And you thought warranties were dull!  

You can read full details of our standard and extended warranties on our website.

The wide world of edge blending

You want to get an extra wide image across the wall - then you’ll probably need to combine two or more projected images to make a single seamless image. This is called edge blending.

The images are firstly overlapped and then visually joined together using an edge blending processor/software, such as the Optoma Chameleon GB-200.  Once these are blended, it is imperative the projectors do not move. If they do, your edge blend will come out of alignment.

So, before you start there are a number of factors to consider.

•    Partition walls, mezzanine floors and suspended ceilings are not ideal environments as they are subject to movement and vibration.
•    Large open spaces such as exhibition halls may get air movement, which may affect alignment.
•    Long mounting arms will amplify any movement so should be avoided.
•    Content resolution needs to match that of the projected resolution. Content with a resolution dissimilar to the combined native resolution of the blended projectors will make set-up more complex and cause the image to be stretched or distorted.
•    Have a minimum overlap percentage of 20% and avoid text on the overlapped areas.
•    Avoid people touching the projectors.  Can visitors reach the installation? Would cleaners or contractors on site knock the projectors?

Laser-phosphor technology: science fiction now science fact

Laser-phosphor technology is advancing rapidly. But what is it, what are the advantages of this technology and for what applications is it best suited?

There are many advantages of lamp-less laser-phosphor light source technology.  For example:
•    There is no lamp and therefore maintenance requirements are minimal
•    Brightness is more consistent than lamp-based projectors, which are subject to brightness fluctuations as the lamp is used (brightness decay) and replaced
•    It is quieter due to higher efficiency and so less requirement for cooling
•    Colour reproduction is brilliant
•    Due to the solid state light engine, the projector is able to operate in unusual positions, including portrait and downward projection

As a result of these benefits, laser-phosphor projectors are ideal for venues where ceilings are high and the projector is fairly inaccessible for maintenance, such as university lecture theatres, digital signage applications and museums/professional installations where usage hours tend to be higher and there are accessibility/maintenance restrictions.

It is also ideal for quieter environments such as smaller meeting rooms or those with low ceilings.

With such a wide choice of projectors – lamp-based, LED and laser - it is important to look at the application and venue to ascertain whether a laser-phosphor projector is the best solution.

If the projector is needed for lengthy usage with minimal downtime or the projector would be fairly inaccessible after installation, then this may be the best option.  

Also if colour accuracy is important, it may also be the best choice – although the colour performance of lamp-based DLP projectors varies with the type of colour wheel used. Some, like Optoma’s EH7700, provide colour wheels options so the colour performance and brightness can be tailored to the application – so it is important to look at all factors.

Optoma has recently expanded its range of laser-phosphor ProScene projectors with the 6,000-lumen ZU650 and the ultra-wide short throw, ZH300W.

The technical bit
Unlike the laser beams you may have seen in Bond films, no raw laser light is emitted from the lens of the projector.  So how does it work and what is the difference between laser and laser-phosphor projectors?

With a pure laser - the red, green and blue light from three laser diode arrays (one each for red, green and blue) is combined then passed through an optical diffuser. It is this diffused light that is used to illuminate the projector’s DLP chip and produce the image.
 
A laser-phosphor projector is slightly different in that it uses one blue laser.  This blue light is diffused and used as the blue light component to illuminate the DLP chip. The blue laser is also used to energise a phosphor wheel that emits yellow light. This is then split into its red and green components and used to illuminate the DLP chip.

How 3D glasses work

When considering a purchase of a 3D TV or Projector, people often neglect to research what type of 3D technology their prospective purchase uses.

Here at Optoma we thought we’d break-down the two 3D glasses technologies available and give you a run-down on what each technology is called and what they do to produce a 3D image.

3D glasses work by displaying a different image to each eye. Our brain then merges each image into one, but with 3D characteristics. This, in turn, “dupes” our brains into thinking that it is seeing an image in 3D, so it creates an image with depth for you.

3D-enabled TVs and projectors work by receiving a 3D signal that gets encoded and sent in a few different ways. The TV or projector has a decoder that takes the 3D signal and shows the left and right eye information as one image that looks slightly blurry when viewed without 3D glasses. The image is an overlapped image of the left and right eye signal. When you wear the appropriate glasses, they separate each image to the corresponding eye to deliver a 3D image.

 

Types of 3D Glasses

There are two types of 3D glasses – Passive Polarized & Active Shutter. Both achieve their 3D visuals in a different way.

Passive Polarized glasses look a lot like sunglasses, not unlike what you get when you visit the movies. They are lightweight and have ample space to accommodate normal glasses underneath if the viewer requires them.

The TV or projector has a special filter that polarizes each line of pixels. This filter makes the odd lines on the screen only visible to the left eye, and the even lines only visible to the right. Your brain then interprets the image as a 3D image. Without the glasses, the image looks normal. One caveat to this system is that the image is not full 1080p as it halves the amount of pixels visible.

Active Shutter glasses use batteries and a transmitter that syncs with the rapidly moving shutters for each eye with the on-screen display.

The 3D image resolution is the same as the 2D image displayed on the same screen. This is because the left and right eye images are shown in sequence rather than at the same time. The 3D glasses sync with the TV or projectors refresh rate to sequence the images that produce a 3D image to the viewer.

 

Optoma 3D Glasses

All of the projectors we produce at Optoma are active 3D. They can however be converted to passive 3D if required with the use of a silver screen and a passive 3D filter.

At Optoma, we manufacture two different types of Active 3D glasses:

ZD302 – These glassed incorporate DLP Link™ technology which use line of sight to the screen to produce a 3D image. If you look away and then back to the screen, the glasses will display a very slight stutter as they re-sync with the projector.

ZF2300 – These 3D glasses use RF (Radio Frequency) technology to sync with the projector. RF synchronization eliminates any potential sync issues and many glasses can be paired to the same projector. As these glasses need an RF emitter to function you will need a “ZF2300 starter kit” that includes an emitter and a pair of glasses.

Projecting the future of retail

We are just back from the Retail Design Expo where we were showing off our projection solutions to retailers from across the UK.  With our partners Projection Artworks and Texas Instruments, we wowed visitors with projection mapped displays using Optoma’s LED and laser DLP projectors on sportswear, luxury goods including watches, technology products and FMCG.  

Projection mapping allows digital content to be applied on or around physical products or spaces.  Research has shown this makes a 41% increase in sales when compared to stores without projection.*

Laser and LED DLP projectors are now a cost effective retail display option. Projections can be daylight visible and maintenance costs for bulbs replacement have been eradicated through LED and laser technology which can provide an astonishing 20,000 hours of impressive, virtually maintenance-free operation.

Optoma's laser and LED projectors

Optoma projectors use DLP technology pioneered by Texas Instruments. This uses millions of mirrors to produce high quality imagery which does not suffer colour degradation over time, as sometimes experienced in other projector technologies.

The event saw UK debut of DisplayMapper that is set to change the face of retail.  DisplayMapper is the world’s first cloud-based, projection-mapping, content management and projector control system which has made global, scalable retail projection rollouts possible. Having created retail projection showstoppers like Harrods’ Faberge installation, Projection Artworks developed DisplayMapper for retailers that want to recreate this type of next-generation ‘magic’ on a smaller and more affordable scale. 

Retailers also saw a new dynamic solution for stores that can sweep marketing messages and imagery across their shop floor, wall and ceilings.  The Mirror Head from the Dynamic Projection Institute comprises a high-tech mirror that is digitally operated and can move either rapidly or slowly to project pictures, videos and text onto any surface.  

Tom Burch from Projection Artworks, Justin Halls from Optoma and Rob Hollands from creative agency Anthem hosted a session at the event’s main theatre to challenge ‘flat panel thinking’.  They shared how a recent POS retail experience installed in a major supermarket stimulated customer engagement and increased sales.
