Classification: CPC G | IPC G

Claim 7:
8. An organic light emitting diode (OLED) display control method, comprising:
with respect to each current frame, counting display lines of a current frame according to a vertical synchronization signal to generate a first count value representing the number of display lines of the current frame;
comparing the first count value and a second count value to generate a judgment result, wherein the second count value is generated by a counting unit before the first count value is generated, and the second count value represents the number of display lines of a previous frame preceding to the current frame;
in response to that the current frame is the first frame after the frame rate changes, calculating a remainder generated by dividing the first count value by a period of an emission control signal, wherein the emission control signal is utilized for control driving an OLED display panel; and
adjusting the emission control signal to compensate for an incomplete period of the emission control signal occurring in the end of the current frame period.
