The silk screen effect (SSE) 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

Cause of SSE

SSE is caused by textured screens used in most rear-projection televisions. Rear-projection television manufacturers use textured screens to increase the viewing angle of the television.

Reducing SSE

SSE can be reduced by properly calibrating the picture controls of the rear-projection 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.
