Claims19
A display panel, comprising:
- a display array comprising a plurality of pixel groups, each of the pixel groups comprising a first pixel column, a green pixel column and a second pixel column sequentially, the green pixel column comprising a plurality of green sub-pixels, the first pixel column comprising a plurality of first sub-pixels, and the second pixel column comprising a plurality of second sub-pixels;
- and
- a driver connected to each of the green sub-pixels, each of the first sub-pixels, each of the second sub-pixels through a data line, the data line through which each of the green sub-pixels is connected to the driver comprising a first branch and a second branch connected in series with the first branch, the first branch being configured with a first switch, the second branch being configured with a second switch and a step-down unit connected in series with the second switch;
- the second switch being turned on and the first switch being turned off in response to that a polarity of a drive voltage of the green pixel column is opposite to a polarity of a drive voltage of the first pixel column and a polarity of a drive voltage of the second pixel column.
A display panel control method applied to a display panel, wherein the display panel comprises:
- a display array, comprising a plurality of pixel groups, the pixel group comprising a first pixel column, a green pixel column and a second pixel column sequentially, the green pixel column comprising a plurality of green sub-pixels, the first pixel column comprising a plurality of first sub-pixels, and the second pixel column comprising a plurality of second sub-pixels;
- and
- a driver, connected to each of the green sub-pixels, each of the first sub-pixels, and each of the second sub-pixels through a data line, the data line through which each of the green sub-pixels is connected to the driver comprising a first branch and a second branch connected in series with the first branch, the first branch is configured with a first switch, and the second branch is configured with a second switch and a step-down unit connected in series with the second switch;
- the display panel control method comprises the following steps:
- obtaining a first polarity of a drive voltage of the first pixel column, obtaining a second polarity of a drive voltage of the green pixel column, and obtaining a third polarity of a drive voltage of the second pixel column;
- in response to that the second polarity is opposite to the first polarity and the third polarity, controlling the second switch to be connected and the first switch to be disconnected;
- and
- controlling the driver to output the drive voltage of the first pixel column to the first pixel column, controlling the driver to output the drive voltage of the green pixel column to the green pixel column, and controlling the driver to output the drive voltage of the second pixel column to the second pixel column.
