摘要

液晶显示系统中，保持型显示特性以及慢响应是造成动态图像质量低下的主要原因。为了研究液晶显示动态图像质量的影响因素，建立了液晶显示动态图像感知效果的模拟模型。模拟模型以显示器的不同响应速度、帧频、背光占空比为参数，同时针对不同类型的显示图像模拟出人眼最终感知的动态图像效果。通过视觉感知实验对模拟图像进行评价并统计分析实验结果。结果表明，背光占空比调制可有效提高动态图像质量，响应速度的快慢与动态图像质量呈正相关关系，帧频提高对动态图像质量的提升受响应速度的限制，即两者之间存在交叉影响。研究结果可为液晶显示系统动态图像质量的提升途径提供理论参考。

Abstract

In the liquid crystal display (LCD) system

the main reasons for the low quality of moving image are the characteristic of holding type display and the slow response. In order to study the influencing factors of moving image quality of LCD

a simulation model of moving image perception effect of LCD is established. The simulation model takes the different response speeds of the display

frame rates and backlight duty ratios as parameters

and simulates the moving image effect of the final perception of the human eye for different types of display images. Through the visual perception experiment

the simulation image is evaluated and the experimental results are statistically analyzed. The results show that the backlight duty ratio modulation can effectively improve the quality of moving image. The speed of response is positively related to the quality of moving image. The improvement of frame rate on the quality of moving image is limited by the response speed

that is

there is a cross influence between the two. The research results can provide theoretical reference for improving the moving image quality of LCD system.
