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.

Abstract: A display device includes a timing controller configured to generate a first control signal using a first clock signal when driven at a first frame frequency, and generate a second control signal using a second clock signal when driven at a second frame frequency different from the first frame frequency, pixels connected to scan lines, data lines, and emission control lines, and an emission driver configured to supply an emission control signal to the emission control lines in response to an emission start signal included in the first control signal or the second control signal. The number of off periods of the emission control signal included in one frame driven at the first frame frequency is equal to the number of off periods of the emission control signal included in one frame driven at the second frame frequency.
