Abstract
A brightness compensation method applied to an OLED display is disclosed. The brightness compensation method includes following steps of: (a) using a skip frame method or an extend porch method to reduce a display frame rate of the OLED display from a first frame rate to a second frame rate, wherein the first frame rate is higher than the second frame rate; and (b) compensating pulse widths of N light-emitting control pulses corresponding to a repeat frame or an extended porch not refreshed, wherein the N light-emitting control pulses correspond to N compensation values, N≥1 and the N compensation values are positive or negative.
Claims11
A brightness compensation method applied to an OLED display, comprising steps of:
- (a) using a skip frame method to generate at least one repeated frame not refreshed to reduce a display frame rate of the OLED display from a first frame rate to a second frame rate, wherein the first frame rate is higher than the second frame rate;
- and
- (b) compensating pulse widths of N light-emitting control pulses corresponding to the at least one repeated frame, wherein the N light-emitting control pulses correspond to N compensation values, N≥1 and the N compensation values are positive or negative.
A brightness compensation method applied to an OLED display, comprising steps of:
- (a) using an extend porch method to generate an extended porch period not refreshed based on a porch period in a previous frame to reduce a display frame rate of the OLED display from a first frame rate to a second frame rate, wherein the first frame rate is higher than the second frame rate;
- and
- (b) compensating pulse widths of N light-emitting control pulses corresponding to the extended porch period, wherein the N light-emitting control pulses correspond to N compensation values, N≥1 and the N compensation values are positive or negative.
