US 8,711,167 B2 · Method and apparatus for generating images using a color field sequential display

Abstract

One embodiment of the present invention sets forth a technique for generating and transmitting video frame data from a graphics processing unit (GPU) to a color field sequential display device. A frame buffer image comprising per-pixel packed color channels is transformed to a frame buffer image comprising regions corresponding to the color channels with vertical blanking regions inserted between color sub-field regions. Each region of the transformed frame buffer image is sequentially transmitted to the color field sequential display device for display of the corresponding color channel. Backlight illumination for each color channel is controlled by the GPU for temporal alignment with display of each color channel during a vertical blanking interval. The GPU may compensate an individual pixel's color channel value based on a corresponding previous color channel value in order to minimize crosstalk between neighboring color fields.
