Abstract: A display driving circuit includes a gamma generator configured to output, to nodes, gamma voltages having different voltage levels, and a selector configured to select one of the nodes to which the gamma voltages are output, and output a voltage of the selected one of the nodes. The display driving circuit further includes a voltage regulator configured to selectively input a first current to the selected one of the nodes and output a second current from the selected one of the nodes, based on the voltage of the selected one of the nodes, to adjust a voltage level of the voltage of the selected one of the nodes to a voltage level of a respective one of the gamma voltages that is output to the selected one of the nodes.

Abstract: The present disclosure provides methods, apparatuses, and non-transitory computer-readable mediums for setting charge sharing times, which may be adaptable to a display panel. In some embodiments, the apparatus includes a pixel array and a source driver configured to drive each column of the pixel array. In some embodiments, a setting method of charge sharing times includes grouping a plurality of pixels of a pixel array in a row direction to form a plurality of pixel groups. The setting method further includes setting a charge sharing time of each pixel group of the plurality of pixel groups according to a quantity of pixel groups in the plurality of pixel groups. A charge sharing time of a pixel group located closest to a source driver in the pixel array is greater than a charge sharing time of a pixel group located farthest from the source driver in the pixel array.
