    摘要: An active matrix organic light emitting diode (AMOLED) panel is disclosed. The AMOLED panel comprises a pixel array, a temperature sensor and a feedback control circuit. The temperature sensor measures the temperature of the AMOLED panel. The feedback control circuit decides the driving current of the AMOLED panel according to the temperature of the AMOLED panel. Since the driving current is inversely proportional to the measured temperature of the AMOLED panel in the present invention, the possibility of subjecting the AMOLED to too high in a temperature and a current is avoided and the lifetime of the AMOLED can be increased.

    摘要: A control circuit for use in an active matrix organic light emitting diode (AMOLED) panel comprising a memory unit and a voltage control unit is provided. The operating time of the AMOLED panel is counted and saved by the memory unit. According to the memory unit's information, the voltage control unit decides a common voltage. The purpose of the present invention is to reduce the common voltage when the turn-on time of the AMOLED panel is increased so that the increase in the voltage difference between the two terminals of an organic light emitting diode (OLED) of the AMOLED panel may be compensated. Thus, the present invention may provide a stable driving current for the OLED and a stable picture definition for the AMOLED panel.

The display apparatus comprises an OLED diode display array and a drive circuit. The drive circuit comprises a detection unit, a clock generating unit, and a timing control unit. The detection unit determines whether a plurality of frames displayed by the OLED diode display array are configured as a dynamic frame. The detection unit generates a first control signal when the displayed frames are not configured as a dynamic frame, and the detection unit generates a second control signal when the displayed frames are configured as a dynamic frame. The clock generating unit generates a clock signal, the frequency of which is a first frequency in response to the first signal, or a second frequency in response to the second signal. The first frequency is greater than the second frequency. The timing control unit sets the screen refresh rate of the display apparatus in response to the frequency of the clock signal.
