Changhong S-CK series ALR (Ambient Light Rejecting) screen is specially designed for UST (ultra-short throw) projectors.
With the advanced optical lens system, S-CK series can efficiently reject ambient light from the ceiling, and present the light from projector only.
The lens system consists of multiple layers, each have the property to reflect angular light. The combination of these layers allows the S-CK to focus on reflecting projector light.
Most of the other ALR screens on the market offers screen gain equals to 0.4 or less which reduced the projection brightness in order to enhance the image contrast. With Changhong’s advanced material technology, the S-CK series managed to offer the scree gain of 0.6 while enhancing the image contrast by 20 times.
The rollable screen of S-CK make the transportation and installation of the screen much more easier which also means lower cost for the screen.
The viewing angle of the S-CK screen is 170 degree which is amazing, it means you can enjoy the high quality image from almost every angle in front of the screen.
The S-CK series use a combination of optical filters and dispersion to tackle the issue. With S-FX series, the image contrast can be enhanced up to 20 times, colour saturation is also enhanced as the ambient light is reflected so you can see more detail with true colour.
Ambient light present will degrade contrast and colour saturation. In higher ambient light situations, this can render the images unacceptable.
The fixed frame design of S-CK series ensure the screen is absolutely flat which is essential for UST projectors. Since the distance between the projector and the screen is so short, any tiny curve on the screen will distort the projected image, only a fixed frame design can avoid such distortion.
