Abstract
A method for image sticking inspection of a light-transmissive device is disclosed. The light-transmissive device is responsive to application of a voltage to electrodes thereof to adjust light transmission characteristics. The method includes: providing light for passage through the light-transmissive device; applying a first alternating current (AC) voltage to the electrodes; applying a direct current voltage to the electrodes; and applying a second AC voltage to the electrodes, and measuring intensity of the light passing through the light-transmissive device during application of the second AC voltage.
