Abstract: A display panel including a plurality of pixels, a plurality of scan lines and a plurality of data lines is provided. The pixels are arranged in an array, and the array includes columns and rows. Each of the scan lines is coupled to the pixels located on the same row. Each of the data lines is coupled to the pixels located on the same column. The data lines are grouped into a plurality of data line groups, and each of the data line groups includes three or more data lines. The data line groups are respectively located between the pixels on the same row. The data line groups are configured to write display data into the pixels when the pixels are turned on. A display driving apparatus and a method for driving the display panel are also provided.

Abstract: A liquid crystal display panel and a display device are provided. The liquid crystal display includes a first common electrode, a second common electrode and pixels. The second common electrode and the first common electrode are electrically independent from each other. First pixels of the pixels are coupled to the first common electrode, and second pixels of the pixels are coupled to the second common electrode. Accordingly, usage or operation of the liquid crystal display panel is more flexible.

Abstract: A driving method of multi-common electrodes and a display device are provided. The driving method includes following steps: providing a plurality of common voltages, in which the common voltages include a first common voltage and a second common voltage, and the first common voltage is different from the second common voltage. During a first period, the first common voltage is set to a first voltage level to drive a first common electrode of a first pixel region in the display panel, and the second common voltage is set to a third voltage level to drive a second common electrode of a second pixel region in the display panel. During a second period, the first common voltage is set to a second voltage level to drive the first common electrode, and the second common voltage is set to a fourth voltage level to drive the second common electrode.
