Abstract
A driving method of a display panel and a display device are provided, wherein the driving method of the display panel can make a sub-pixel to be driven disposed in a splicing region display normally by compensating the sub-pixel to be driven disposed in the splicing region. A dark line appearing in the splicing region is eliminated, and a technical problem of splicing dark line appearing in the splicing region of a display device adopting spliced mini-LEDs is alleviated.
Claims20
A driving method of a display panel, comprising steps of:
- obtaining a first driving gray scale of a sub-pixel to be driven;
- determining a location of the sub-pixel to be driven, and obtaining a splicing region compensation factor when the sub-pixel to be driven is disposed in a splicing region;
- calculating a second driving gray scale of the sub-pixel to be driven according to the splicing region compensation factor;
- and
- driving the sub-pixel to be driven by the second driving gray scale.
