Silk screen effect
Encyclopedia
Silk Screen Effect is a visual phenomenon seen in rear-projection televisions. SSE is described by viewers as seeing the texture of the television
screen in front of the image. SSE may be found on all rear-projection televisions including DLP and Liquid Crystal on Silicon
(LCoS). The effect is most visible when viewing bright white or very light colored images. Viewers also report seeing "sparkles" when viewing very bright colored images.
SSE's nomenclature comes from the visual appearance of this effect, which is likened to viewing an image through a silk
screen. SSE should not be confused with the screen door effect, another visual phenomenon seen in rear-projection televisions.
manufacturers use textured screens to increase the viewing angle of the television.
. SSE is most prominent when the contrast
and brightness are set too high. Adjusting the brightness and contrast
and properly calibrating the picture controls can reduce SSE.

Liquid crystal on silicon
Liquid crystal on silicon is a "micro-projection" or "micro-display" technology typically applied in projection televisions. It is a reflective technology similar to DLP projectors; however, it uses liquid crystals instead of individual mirrors. By way of comparison, LCD projectors use...

Contrast is the difference in visual properties that makes an object distinguishable from other objects and the background. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view...
