Research On The Backlight For TFT LCD And Its Quality Improvement

Recently, TFT-LCD has gradually come into personal families, which is so close to our lives. From mobile phone,Monitor to LCD-TV, from PM STN LCD to AM TFT-LCD, LCD has become more popular than ever. Following the development of TFT-LCD technologies, the applicable field of TFT-LCD, especially color TFT-LCD, is turning widely all the time. Presently, Back Light has been a significant subject, and become a hot area in search and development. Attributed to the market of TFT-LCD, the development of back light industry has become a prosperous vision.This subject, mainly considering the fact of manufacturing and coming from design of back light,integration of every optic film and frame of each segments, through ethic and experiment proving, mostly combining mass production and demands of customers, purpose to improve every parameters of back light, and use the optic experiments to certificate.Secondly, Lamp broken is normal defect in TFT-LCD. CCFL, the material of which is glass, is easily to broken by outer striking, and makes Module not to be lighted. Under analysis, the experiment finds the root reason, and through several improvements, we control the defect in a low ratio, fulfils the customers.In the end, No video is also normal defect in TFT-LCD Module, because it happens so frequently in the customers, bringing company lost and reverse effects. Due to CCFL cooperation with convert, the conclusion of the document would give a help to improve quality of our company, and have a grand practical meaning.
