Abstract:
Embodiments are directed to image processing methods to improve display quality while using a limited number of pulses and to correct the error between the reflectance and the desired gamma. The complexity of the hardware used for driving a display device may then be reduced to minimum. In addition, in various embodiments the method can also be used to compensate for the change of an optical response curve due to batch variation, temperature change, photo-exposure or aging of the display device.
