摘要

在大屏幕视频显示的研究中

通常将侧重点放在显示驱动电路的优化上。本文从人眼的主观视觉理论出发

讨论了大屏幕视频图象显示与主观视觉之间的关系。并提出了一种很好的校正理论。经过实验检验

它能在图象列信息相同时

不管背景图象如何

均能使显示屏保持相同的亮度

使显示的视频图象的质量得以提高.

Abstract

In the study of large LED panel video display

we always put the main point in the optimization of driving circuit

and seldom care about the visual sensitivity and image quality. This paper

based on human's visual sensitivity

discusses the relationship between large screen video display and the visual sensitivity

and put forward a correction theory. Experiment resultes show that it can supply the same luminance when the columns have the same information and thus quality of image can be improved.
