Classification: CPC G | IPC G

Claim 0:
1. An organic light emitting diode (OLED) display control circuit, comprising:
a counting unit, configured to, with respect to each current frame, count 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;
a judgment unit, coupled to the counting unit, and configured to compare the first count value and a second count value to generate a judgment result, wherein the second count value is generated by the 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;
a remainder calculation unit, coupled to the judgment unit, and configured to, in response to that the current frame is the first frame after the frame rate changes, calculate 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
a signal compensation unit, coupled to the remainder calculation unit, and configured to adjust the emission control signal to compensate for an incomplete period of the emission control signal occurring in the end of the current frame period.
