摘要/Abstract

摘要： 针对半导体激光器作为背光源的液晶显示器背光模组, 应用TN型E7液晶构建抑制散斑装置, 并分析频率与电压对散斑抑制效应的影响. 结果表明, 散斑对比度由6.52%降为2.80%, 使人眼无法察觉散斑.

关键词: 激光显示, 激光散斑, 激光液晶显示器, 散斑抑制

Abstract: In view of the semiconductor laser as a backlight source of liquid crystal display (LCD) backlight module, we used TN type liquid crystal E7 to construct speckle suppression device, and analyzed the effects of frequency and voltage on speckle suppression. The results show that the speckle contrast is reduced from 6.52% to 2.80%, which makes the human eye can not detect speckle.

Key words: speckle suppression, laser display, laser liquid crystal display, laser speckle
