摘要
文章提出了应用于液晶显示(LCD)控制器的动态抖动算法及帧速率控制技术。抖动算法极大的改善了显示图象的平滑度,帧速率控制技术大大增加图象灰度而明显降低图象的抖动和赝象。结果显示在LCD控制器中采用动态抖动算法及帧速率控制技术,如果每一象素数据的位宽是8比特,则单色图象的显示效果可高达256级灰度,彩色图象高达2563彩色。
Dynamic dithering algorithm and frame rate control technique applied to LCD controller are presented. The dynamic dithering algorithm on pixel data to advantageously increase smoothness of an image displayed. The frame rate control technique generates more gray,shades, which may reduce flicker and visual artifacts. Results show that the gray shades displayed on images can be up to 256 for monochrome LCD panels or 2563 colors for color STN LCD panels respectively by using dynamic dithering algorithm and frame rate control technique if each encoded pixel data is 8 bits.
