Abstract
An organic light emitting diode (OLED) display control circuit and a control method thereof are provided. The OLED control circuit includes a counting unit, a judgment unit, a remainder calculation unit and a signal compensation unit. The counting unit counts display lines of a current frame according to a vertical synchronization signal to generate a first count value. The judgment unit compares the first count value and a second count value to generate a judgment result. The second count value represents the number of display lines of a previous frame preceding to the current frame. The remainder calculation unit calculates a remainder generated by dividing the first count value by a period of an emission control signal. The signal compensation unit adjusts the emission control signal to compensate for an incomplete period of the emission control signal occurring in the end of the current frame period.
