Abstract
A method for adjusting brightness includes detecting whether damage occurs on a light guide plate of the display device, determining a damage position and a damage extent of the light guide plate when the damage occurs on the light guide plate, and compensating for a change value of brightness generated due to the damage by adjusting the brightness of the display device corresponding to the damage position, according to a predetermined correspondence between damage extents and change values of brightness. The method for testing a display device includes applying a destructive operation to the display device to be tested, detecting a damage extent generated by the destructive operation and a change value of brightness correspondingly generated in a damage region, and creating and storing a correspondence between the damage extent and the change value of brightness.
