Abstract
ADS TFT-LCD module easily produces Dark light leakage due to the problem of poor light leakage sensitivity.Poor light leakage sensitivity appears with high brightness, large leakage range and yellow color when an external force is applied.In this paper, the effects of glass, LC and PS on the sensitivity to dark light leakage were studied.The result shows that the reduction in glass thickness can improve brightness change, and the decline of Δnd can improve yellow color when an external force is applied.For example, when external force 30 N, 0.5 T glass Lo brightness is lower than 0.7 T Lo brightness by 33％.The result reveals if the Δnd is the same, decreasing Δn or increasing K can reduce LC scatter, which can improve high brightness and large range light leakage.For example, when the external force 30 N, the Lo brightness of the scattering value of 0.027 is reduced by 28％ compared with the scattering value of 0.038.The result also shows that the increase of PS support density can improve high brightness and large range light leakage.For example, the Lo brightness of PS density of 3 168 μm2/mm2 is lower than PS density of 2 364 μm2/mm2 by 22％.The solution to light leakage sensitivity was established by the research and its theoretical explanation was also given.关键词
