Patent ID: 7372523

Claim:
A display apparatus comprising: a light source; a first liquid crystal display on the light source, wherein the first liquid crystal display is configured to allow a variable amount of light transmission based on a first control signal; a second liquid crystal display on the first liquid crystal display, wherein the second liquid crystal display is configured to allow a variable amount of light transmission based on a second control signal; and a display circuit that is configured to generate the second control signal to separately address pixels on the second liquid crystal display to separately vary the amount of light transmission through individual ones of the addressed pixels for generating images, and configured to generate the first control signal to separately address pixels on the first liquid crystal display to vary the amount of light from the light source that is transmitted through individual ones of the addressed pixels to adjacent individual ones of addressed pixels of the second liquid crystal display based on the amount of light transmission through the adjacent individual ones of addressed pixels of the second liquid crystal display.
