Abstract: Embodiments of the present disclosure provide a method for setting, by a computing device, a bias voltage of a driver integrated circuit that supplies voltage to a display panel. The method includes: selecting one of a plurality of pre-stored scenarios based on a change in a flicker index and applying a bias voltage to the display panel according to a level based on the selected scenario, and recording, to the driver integrated circuit, a level of the bias voltage which corresponds to a minimum value in a fitted quadratic function. According to a system and a method for setting the bias voltage according to embodiments of the present disclosure, the level of the bias voltage that minimizes the flicker phenomenon by minimizing a change in luminance of the display panel based on the bias voltage can be calculated through minimal measurements.
