Abstract: In 21st century,TFT-LCD plays a more and more important role in display industry, which has been used in Smartphone ,notebook and industrial devices. Industrial application requests steady image display in tough environment, which means high temperature such as 85¡É and high humidity. However, as the important element of the backlight, the lighting guide plate(LGP) which is usually made of polymethyl methacylate (PMMA) which partial melt at about 85¡É. Because it is the important element of the backlight and this action would affect the backlight¡¯s optical characteristics, especially luminousness and uniformity(aways above 80%). In this paper, we discuss a method to achieve good performance after high temperature and high humidity Operating Test (THB) by adjusting LGP pattern.
