Silicon Crystal Reflective Display (SXRD)
SXRD is Sony's adaptation of Liquid Crystal on Silicon (LCoS) micro-
display technology. The SXRD technology is similar to the LCD
technology use in previous rear projection and direct TV products in that
is uses liquid crystal materials to pass and block light to form the picture
you see, however, this is where the similarities stop.
The primary differences between SXRD and the standard LCD
technologies are as follows.
LCD Technology
o Is a transmissive device – light is directed into the rear
of the panel, the passes through the panel and the liquid
crystal material. The light only passes through the liquid
crystal material once. The liquid crystals modulate the
light as it passes through the panel.
o The liquid crystals when layered from a 90-degree
angular orientation after so many layers. Therefore, light
is completely passed when no potential is applied to the
liquid crystals.
o The Panel depth is thicker then the SXRD technology
because the LCD drives and liquid crystal material are
place on separate layers in the panel.
o The distance between the pixels is greater than the SXRD
technology (causing the screen-door effect) because the
matrix wiring and switching elements must be covered
with a solid plastic grid structure.
