摘要
Abstract
With the development of display industry,market has the higher requirement of products quality. Especially for vehicle display field,the brightness of backlight is almost more than 10000cd/m2,w hich may enlarge small defects in display screen to impact display quality.As black uniformity is a crucial characteristic of image quality,the investigation of the structure and designing of liquid crystal display module which can generate black light leakage have been in progress for optimizing uniformity of black state to achieve best display quality.Those experiments were designed on the basis of external forces for Panel,mech-anism interference and FPC stress to catch optimum methods or control standards for best black uni-formity.The experimental results show,the module black uniformity has been increased more than 80% by decreasing interference stress,which was implemented by controlling the flatness of backlight and metal frame,optimizing the design of buffer tape,decreasing bend stress by optimizing structure and shape design of FPC,improving panel's stress resistance ability by reducing panel thickness and increasing dimension of Polarizer.关键词
