摘要
针对液晶显示器灰度等级低、色彩偏移及需白平衡调整等现象,利用PD(Pixel Dithering,像素抖动)与FRC(Frame Race Control,帧速率控制)算法基于FPGA系统产生感应灰阶,从而提出了一种基于此感应灰阶技术的液晶显示器灰度增强、色彩偏移校正及白平衡调整的方法,并在液晶显示器中实际应用。实验结果表明:该方法算法简单,计算量小,采用该方法,极大地提升了显示效果,使画面层次感更丰富细腻、色彩更逼真。
According to low grey-scale,color-offset and white-balance excursion of LCD,methods of grey-scale enhancement,color-offset calibration and white-balance adjustment are proposed with the help of spatial grey-scale by PD and FRC algorithm based on FPGA system,and also realized.The experimental results verified the proposed methods are simple in calculation and increase display quality of grey-scale and color greatly.
