  • Patent number: 7812795
    Abstract: 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.
