LED显示屏逐点色度亮度校正技术讲座

A Lecture on the Technology of Color and Brightness Correction of Pixel of LED Display Screen

为了获得优良的画质,必须采用逐点亮度色度修正的方法,提高显示屏的一致性、均匀性。文章以技术讲座的方式介绍色度亮度修正的原理、方法及相关的问题。笔者使用三种最常见的仪器设备对LED显示屏箱体或模组进行了测试,介绍了试验的结果和笔者的体会。全文共五讲(本文为第二讲)和一个附录,附录中包含部分测试数据和有关资料。

In order to make the picture quality of LED display screen to be perfect,the technology of color and brightness correction of every pixel is indispensable.Using three typical instruments,including RI＇s PM,Delta＇s ICAM and Canon EOS 40D,we did some experiment of pixel color and brightness correction on display panel or module.In this lecture,these tests and author＇s experience are described.
