ORGANIC LIGHT-EMITTING DIODE DISPLAY PANEL

摘要

An organic light-emitting diode display panel is disclosed herein. The organic light-emitting diode display panel includes display units. Each of display units includes an organic light-emitting element, a light-driving circuit and stages of shift register connected in series. The light-driving circuit drives the organic light-emitting element according to a light-emitting control signal. Each of the stages of the shift register includes a shift register circuit and a control signal output circuit. The shift register circuit generates a current stage shift signal according to a previous stage shift signal and a first clock signal. The control signal output circuit outputs the light-emitting control signal according to the current stage shift signal and a previous stage carry signal. The enabling period of the light-emitting control signal is determined by the time period between the enabling period of the current stage shift signal and the previous stage carry signal.
