提出一种既有赖于周期权重又依赖于开态电学参数的权重的混合灰度方法, 这种方法可以驱动4K显示分辨率的AMOLED。文中根据n位图像数据的比特位数值, 把每帧分割成n个子帧, 像素的灰度将由占空比及电学参数(比如电压和电流大小)二进制权重共同控制。

A hybrid scaling method, in which frame is binary weighted by either the duration or the “on”-electrical-parameter, has been proposed for driving 4K AMOLED display. In this paper each frame has been divided into n-sub-frames corresponding to the n-bit image data, and the grayscale of pixel is controlled by the duty ratio, as well as the weight factor of electrical-parameter (such as the level of voltage and current).
