Abstract
In one embodiment the present invention includes a display system for displaying video. The display system includes a backlight layer and an LCD layer. The display system controls the backlight layer and the LCD layer to emulate a cathode ray tube response. This emulation may be accomplished by applying a gamma function to a gamma corrected input signal. In this manner, the effects resulting from the “crushed blacks” phenomenon may be reduced.
