Image sticking measurement method for liquid crystal display device
Abstract:
A method for measuring an image sticking defect in a liquid crystal display device includes the steps of grounding a liquid crystal cell, the liquid crystal cell includes an alignment layer, applying a first alternating current voltage to the liquid crystal cell, measuring a first capacitance of the liquid crystal cell, applying an electrical stress to the liquid crystal cell, measuring a second capacitance of the liquid crystal cell, and calculating a capacitance difference between the first capacitance and the second capacitance.
