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.

Setting method of charge sharing time and non-transitory computer-readable medium

A display driving integrated circuit includes a common voltage buffer configured to provide a common voltage to a display panel and when a line outputting the common voltage and a gate line are short-circuited, apply a first current to the gate line or receive a second current from the gate line; a current generator configured to sum currents respectively corresponding to the first current and the second current and output an output current obtained by the summing; and a current detector configured to convert the output current into an output voltage and output a high or low signal based on a result of comparing the output voltage with a preset voltage.
