| 摘 要： | 在分析帧比率控制(FRC)算法的基础上,提出了一种空间扩展FRC算法,将非线性时间混色扩展到显示的屏幕空间,可以保证画面的平均亮度基本不变.从理论上推导了采用该算法时静态图像相邻两帧间图像明像素数的最大差异,并使用基准图形进行了测试.该FRC被实现于一个液晶显示控制器,经实际的制造工艺分析,具有较好的硬件实现特性.

| Abstract: | Based on the ready FRC algorithms,the paper proposes a new FRC algorithm using space expansion.The non-linear FRC sequence was expanded to the whole screen,thus the average brightness can be almost stable.The Maximum diversity of the amount of ON pixels between two frames were calculated theoretically and tested by pictures as benchmarks.We also integrated this FRC module into a LCD controller.The analysis on practical manufacturing parameters shows that this FRC has good implementation characteristics. |
