Extreme Projector Screen Test Outdoors, proves many points and one in particular that an ICE Screen really does have Magic in the Screen.

Now lets be honest, have you ever thought you could use a projector in a well lit environment, say like outdoors and achieve a high quality bright image? If you said No it is impossible, then you are not alone. So why is it that people the world over still believe they need a incredibly powerful and VERY expensive projector? Even those in the audio visual industry believe that it is not possible, unless you go and spend $200,000 then you might get an image bright enough.

This week we astounded an number of people when we proved that it is not the projector that is the key to achieving a high bright image outdoors, which is contrary to what they have been told as long as they can remember. The screen is the absolute first point to consider, get this wrong and you will be chasing around in circles forever, trying to get an image that you can view in a well lit environment. The washed out image is so common it is come to the point that folk believe that simply the projector is not bright enough. To this we say they are 200% absolutely wrong and we can prove it before their very own eyes.

The point I want to draw your attention to in the above photo:

1 – Notice how the image is very bright on the left and right screen areas
2 – The middle white area you can barely make out any content
3 – A single projector is covering the full area

And yet we get a dramatically different type of image brightness display quality on the two screen surface areas.

First the point of adding the Matte White Screen section in the photo is purely for your direct comparative benefit. A matte white screen is the cloth material used on the bulk of screens world wide in Government meeting rooms, classrooms, offices, universities, home theatre. It typically has a rated Gain efficiency of Gain 1. This means the amount of light projected is reflected and displayed at 100%. (further detail about Gain below)

So the big question you are probably asking is, “How is that possible?” You have probably tried using the projector yourself with all the lights on, curtains open and know only to well that you have a poor quality image. Many churches realise this problem only to well where the projected words for songs and images are almost washed out.

The big misunderstanding people make is that they think the white or grey roll up screen (or tensioned screen) is the correct surface (their first mistake) and that they have come to expect the image will be washed our, lacking in contrast if any light is in the room from switched on lights of sunlight coming into the room. So you might say that people have come to expect in their thinking that the only way to solve this is to either sit in a darkened room or buy a far brighter projector (for which invariably no budget exists!)

An explanation of Gain (from Wikipedia)
A Gain of 1.0 means the amount of light that is projected on the screen returns to the viewer at the same brightness: none is absorbed and all is re-radiated with perfect uniformity from all viewing angles. If one was to isolate certain rays striking the screen, he/she would see the rays diffuse to form a perfect hemisphere shape. A block of magnesium carbonate (MgCO3) or a matte white screen will result in a gain of 1.0. This is fine in theory or in a dark room but for most applications projectors are not used in a dark room where a Matt White screen can perform at its best.

A screen with a Gain of 1.0 will reflect the same amount of light as that from a matte white screen. A screen rated at 1.5 gain will reflect 50% more light as from a matte white screen. A screen with a 0.9 gain will reflect 90% of the light compared against a matte white screen.

Gain is measured from the vantage point where the screen is at its brightest, which is directly in front and perpendicular to the screen. When the measurement is taken for light targeted and reflected perpendicular to the screen. Technically the measurement of Gain at this point is known as Peak Gain at Zero Degrees Viewing Axis. If you move to the side and view the screen at an angle the brightness of the projected image drops. The angle at which the gain reading drops to 50% of the peak value is known as the Half Gain Viewing Angle. A person viewing the screen from this angle will see an image half as bright as the person seated at the center position.

Daytime Projection Screen

In the photo (above and below) taken outdoors early evening when the meter measured 73.5 lux. This is about the darkness that you might have also when in a home theatre setup. Take note of the lack of contrast on the matte white strip and the white cloth background and yet on the ICE screen the brightness is substantially larger. The reason is the Gain 20 factor performance of the screen surface efficiency.

Whilst we have shown the screen outdoors the ICE Digital daytime screen is not manufactured for permanent outdoor installations. If you use the ICE Daytime screen outdoors your results may vary according to many different factors.

Used in conjunction with tablets and interactive screens the ICE Digital Daytime Lens Screen becomes the perfect large format screen to display the interactive output without having to actually touch the screen.

Important points to remember:

– ICE Digital Daytime Lens Screen can be used with any type of projector
– Makes any projected image up to 2000% brighter than using a Matte White Screen
– A Matte White screen only works when the environmental light is dramatically reduced.
– Long term you will always achieve a brighter image at a lower price than any other combination of screen or projector.
– Results can vary depending on many reasons.
– Cost wise, to achieve a high quality bright image in a well lit environment, you will always achieve it at a lower cost if you factor in a ICE Daytime Screen, than throwing money at a higher brightness projector with a Matte White Screens
– Our ICE Lens screen does not wear out and will always last longer than projectors.

We used a Digitech QM-1593 light meter for these measurements to provide some objectivity. Any inaccuracy in lux readings has no impact on the comparative views. Learn more about LUX levels here.

Amazing Daytime Outdoor projection success baffles many people.

Daytime projection capability is not understood by many people as it goes against everything they have been told, seen, and experienced.

ICE AV has always been pushing the boundaries of audio visual capability and technology integration and with our slogan of “Magic is in the Screen”. The ability of projecting in well lit environments is seen as a No No by many people and for Managing Director, Kevin Andreassend it is perfectly understandable as the AV industry and people in general have been so accustomed to using poor performing and inefficient matt white screens that simply discard a lot of the light from the projector.

Understanding that the screen is the crucial part to start with first rather than the projector is an odd position as most projector buyers are under the misunderstanding that to get a brighter image you need a brighter projector. This failure in understanding comes about because of habit, misinformation and failure to realise than a Lens based screen has amazing optical properties as can be clearly seen in this direct object comparison between a Matt White Screen and a ICE DDT Digital Daytime projector screen.

Daytime Projection – High performance projection screens can make a huge difference.

Projection screens have a vital roll in a world market that is becoming screen orientated. What most people still misunderstand is that there are screens and there there are screens. However due to ignorance and lack of knowledge many still conceive that you need a very bright projector or dark room to achieve commercially acceptable projected images in well lit environments.

Having said the above we do not claim that we can out perform the brightest object in our solar system (the sun) with a $2,000 projector. What we do state though that if one understands and accommodates all the parameters of the environment, screen placement, appropriate projector you may easily achieve commercially acceptable images that a Matt White screens and projector can never deliver in a well lit environment. In certain cases for large indoor displays it can be a lot more affordable than an LED screen, especially when resolution comes into the equation.

Daytime projection

72 inch ICE Digital Daytime projection screen inside the foyer of the Australian Maritime Museum in Darling Harbour, Sydney.

In the above picture this image was perfectly displayed. There is a slight hot area in the centre that the camera recorded, however to the human eye it was not noticeable and overall the picture was very uniform and pleasing to the view. The receptionist at the counter certainly thought so and had never seen an image so bright in the foyer.

There was no need to want to use a brighter projector in this well known foyer. The museum had previously tried projection in the foyer but gave the idea away, as using a traditional Matt White screen it was not possible to achieve a commercially acceptable image let alone a perfectly bright image.

 Most people settle for a TV set or computer monitor of some description and size. However unless you’ve just bought one of the new 100″ plasma TVs (and refinanced the house loan!) or project in a dark room you’ll never get the size and quality you dream about and certainly what is required for pleasing quality projection images

This is where can really help clients who desire commercially useful projected images in well lit environments … with the correct projection screen technology it is possible to increase a projected brightness by up to 2,000% brighter than a matt white screen without turning the lights off or getting a far brighter unaffordable projector. Some AV companies and clients claim this is heresy  until they view the images!

Check out this slide presentation on the ICE Digital Daytime Screens.

Just to prove the point that it is possible to project outdoors under 5,000 lux light of daylight with a 4000 ANSI projector and get a extremely impressive image here are some very poor quality photos that really do not do justice to what was a perfect image that we made today for a USA client.

The revolutionary ICE Lens screen allows projection in highly lit environments. This photo has been unaltered apart from the text comment which has been added. The lux level was just on 5000 lux in the shade at the screen. In the sunlight it was well over 20,000 lux. The white strip in the middle is a piece of matt white Da-Lite screen material.

The strip of matt white screen in the middle of the ICE Lens screen has been placed there to show you an exact comparison of the two screen types. Never believe anyone who states they can get an incredibly bright image by simply using a 2500 – 3000 ANSI lumen projector onto a Matt White screen and keeping all the lights on or out on their back deck in the direct afternoon light.

In reality the human eye, read my two eyes 🙂 – saw an image far superior to the photograph, however due to the limits of the digital camera used with DLP projector the whites are not vivid white due to the colour cast effect on the LCD camera from the DLP projector wheel. In reality it was a brilliant white.

Here is a video with one of our SimDeck PET250 cars on a mobile platform taken in the same location.

Most people believe it is impossible to achieve this performance with a projection screen and projector in this type of bright environment….even the pro AV guys!! The screen is in the shade due to the trailer roof and there is no direct bright light source facing the screen apart from the projector.

If you are into any type of information display you are doing yourself a huge dis-service if you ignore an ICE Lens Screen as your option or continue with your pre-conceived ideas that projection can only achieve perfection in a dark room and could never match LCD. Many times we achieve far better that LCD could ever match – size for size, brightness and dollar for dollar. ICE Digital Daytime will always succeed.


ICE Uniformity

For actual projection use we would never leave the screen directly in the bright direct sunlight but bring it forward into the shade.  If the screen in the position as shown in the photo was aimed so the centre of the cone was aimed at a person the reflection would be blinding bright (as it was) and most uncomfortable, just like it is being reflected onto the ground.
