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 △nd can improve yellow color when an external force is applied. For example

when external force 30 N

0.5 T glass

L

brightness is lower than 0.7 T

brightness by 33%.The result reveals if the △

decreasing △

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

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
