中文摘要：

介绍了主流显示器件的灰度调制方法，分析了现有方法的缺陷。以人眼视觉特性为基础建立数学模型，提出了一种灰度优化算法，并通过FPGA验证了其可行性。仿真表明该算法的结果更贴近理想亮度曲线，在256灰度等级下能提高多达32倍的闪烁频率，有效减小由于闪烁给人眼带来的不适，增强在播放动态画面时的稳定性。

英文摘要：

The gray modulation method is introduced in this paper, in which the flaw of the mainstream gray modulation is analyzed. According to the human visual characteristics an advanced algorithm based on the optimum mathematic model is put forward. The feasibility of the algorithm is proved by FPGA hardware and VHDL program. Simulations and analysis indicate that such optimum algorithm can produce better output that fits to the ideal curve. Compared with the former, it improves the peak flicker frequency up to 32 times at 256 grayscale, achieves better color performance, reduces the visible flicker, and enhances the stability of dynamic image.
