ORGANIC ELECTRO LUMINESCENCE DISPLAY EFFICIENT DRIVE METHOD

摘要

A method for driving an OELD device is provided to enhance illumination efficiency by applying high efficiency driving voltages to organic electroluminescence pixels. In the PWM(Pulse Width Modulation) operation of pixels installed in an OELD(Organic Electroluminescence Display) device, the magnitude of the extinction voltage(VdL) of data electrodes is selected and driven at a range between a 0 voltage and a threshold voltage(Vth). In the PWM operation of the pixels installed in the OELD device, the magnitude of the non-selection scan voltages of scan electrodes is selected and driven at a range between the 0 voltage and threshold voltage when the non-selection scan voltage is subtracted from an illumination voltage(VdH).
