Abstract

A display driving circuit applied to a display includes a detection unit, a counting unit and an adjusting unit. The detection unit is configured to detect N pulses of an emission control signal of the display in a frame and define a frame porch interval increasing unit accordingly. The frame porch interval increasing unit equals to 1/N frame. N is a positive integer. The counting unit is coupled to the detection unit and configured to count frames according to a first refresh rate. The adjusting unit is coupled to the detection unit and the counting unit and configured to insert M frame porch interval increasing units every time when the counting unit counts L frames to adjust the first refresh rate to a second refresh rate, wherein the second refresh rate is lower than the first refresh rate. L and M are positive integers and L≥M.
