The gain of a projection screen is the ratio of it reflectivity compared to a perfect matte white (lambertian diffuser) standard (magnesium carbonate or sulfate are typical examples). Measures the ability to reflect light from a projection screen. The higher the number, the greater the amount of reflected light to release the viewer (s).

The number of different colors that can be played on-screen images, the higher this number, the better the color reproduction. A High-Contrast Optical System that achieves a contrast ratio as large as 1000:1, exhibiting more natural and smooth gradation.
A three-chip DLP projector uses a prism to split light from the lamp, and each primary color of light is
When a video signal is sent to a display device, the intensity of the picture should - ideally - match the value of the signal. So, if we send a signal at 50% of its maximum value then the display should be 50% of its maximum intensity.
A process that compensates for the deviation in connection with the brightness of the display and the input voltage. The
