Patent ID: 11074854

Abstract:
A driving device and an operation method thereof are provided. The driving device drives a plurality of light-emitting control lines of an organic light emitting diode (OLED) display panel. The light-emitting control lines are divided into a plurality of groups. The driving device includes a control circuit and a plurality of logic gates. The control circuit generates a global light-emitting control signal and determines a duty cycle of the global light-emitting control signal. Any one of the logic gates determines whether to transmit the global light-emitting control signal to the light-emitting control lines of a corresponding group among the groups. When the global light-emitting control signal is transmitted to a corresponding light-emitting control line among the light-emitting control lines, a pulse of the global light-emitting control signal may light up a plurality of pixels connected to the corresponding light-emitting control line.
