  • Patent number: 11990097
    Abstract: A display driving structure includes a drive component and at least a switching component. The drive component is connected to data lines in pixel groups to provide a one-to-one corresponding data signal to each of the sub-pixels through the data lines. A first input terminal of the switching component is configured to receive a p-th row of scanning signals, a second input terminal is configured to receive a (p+1)-th row of scanning signals, a first output terminal is connected to a p-th row of the scan lines in the pixel group, a second output terminal is connected to a (p+1)-th row of the scan lines in the pixel group, and a control terminal is configured to control the conduction sequence of signals in the switching component according to the polarities of the data signals received by adjacent two sub-pixels connected to each column of the data lines.

  • Patent number: 11961439
    Abstract: A display panel, a driving method and a display device are disclosed. The display panel is divided into a first area and a second area arranged along a data line direction. Multiple sub-pixels corresponding to a same row of scan line are connected to data lines in one-to-one correspondence. In the first area and second area, each column of sub-pixels is arranged between two adjacent data lines, where the same column of sub-pixels includes multiple sub-pixel groups, each of which includes at least one sub-pixel. Among two adjacent data lines, one data line is connected with the sub-pixels in the odd groups, and the other is connected with the sub-pixels in the even groups. The sub-pixel groups in the first area and the corresponding sub-pixel groups in the second area are axially symmetrical with respect to a boundary line between the first area and the second area.
