Abstract
With the increasing of pixel density, the wiring becomes denser and the aperture ratio becomes smaller, which leads a loss in transmittance of LCD products. It is a big challenge to develop a high resolution LCD display without much loss in brightness. In this paper, We report a novel method to increase transmittance of the liquid crystal display by thin films optical optimization. We optimized the transmission curve of array substrate by thin film optical model, which is match well with the backlight spectrum and the transmission curve of LC, CF substrate and polarizer. This method was applied in LTPS and oxide LCD product. The transmittance can be improved by 5.5% and 5.06% compared with the original plan, without much influence on electrical characteristics and reliability of the products.
