  • Organic light-emitting diode (OLED) pre-charge circuit for use in a common anode large-screen display
    Patent number: 7079092
    Abstract: The present invention is a pre-charge circuit integrated within the drive circuitry of a common anode, passive matrix, large-screen organic light-emitting diode (OLED) display device for overcoming the inherent capacitance characteristics COLED of the OLED devices therein. More specifically, a first pre-charge circuit of the present invention includes a MOSFET device integrated within the normal drive circuitry for applying a pre-charge voltage to the cathode of a given OLED device just prior to the desired “on” time, thereby overcoming COLED rapidly. A second pre-charge circuit of the present invention integrates within the normal drive circuitry a method of connecting the anode of a given OLED device to a positive voltage while concurrently connecting the cathode to ground just prior to the desired on time, thereby overcoming COLED rapidly.
