    • 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.
    • 本发明的一个实施例提出了一种用于从图形处理单元(GPU)生成和发送视频帧数据到彩色场顺序显示装置的技术。 包括每像素打包色彩通道的帧缓冲器图像被变换到包括与颜色通道相对应的区域的帧缓冲器图像,其中垂直消隐区域插入在彩色子场区域之间。 变换后的帧缓冲图像的每个区域被顺序地发送到色域顺序显示装置,以显示相应的色彩通道。 每个颜色通道的背光照明由GPU控制,用于在垂直消隐间隔期间与每个颜色通道的显示进行时间对准。 GPU可以基于相应的先前颜色通道值补偿单个像素的颜色通道值,以便最小化相邻色域之间的串扰。
