Patent ID: 8289266

Claim:
A liquid crystal display (LCD) device comprising: a controller configured to be operably connected to driving circuitry for a plurality of liquid crystal (LC) cells and further configured to be operably connected to an illumination control system for an array of light emitting diodes (LEDs) arranged behind said LC array and in alignment therewith, said array comprising at least three different LED colors, said controller configured to: receive input image data, and based thereon to produce a plurality of color display frames, each said color display frame comprising color selection data for each of a plurality of display colors and color transmittance data corresponding to each said display color, wherein said controller is to produce said plurality of color display frames by correcting for color phase shift between rows of said display, sequentially send the color transmittance data for said color display frames to said driving circuitry for controlling transmittance of said LC cells, and sequentially send in synchronization with said color transmittance data said color selection data for said color display frames to said illumination control system for selectively activating said array of LEDs, wherein for at least three of the display colors, the respective color selection data represents selective illumination of LEDs of a single color, and for at least one of the display colors, said color selection data represents selective illumination of LEDs of a plurality of colors, thereby sequentially producing color display frames representing more display colors than the number of LED colors.
