Abstract

The invention discloses a driving method of a display panel and a display device. The display panel comprises a plurality of pixels arranged in an array, wherein each pixel includes at least three colors of sub-pixels. The method comprises the steps of obtaining the distance between a viewer and the display panel; judging whether the distance is greater than a preset threshold or not; if it is determined that the distance is greater than the threshold, determining the position and number of each sub-pixel to be lightened; and determining a data signal corresponding to each sub-pixel to be lightened according to the position of the sub-pixel to be lightened, and lightening the sub-pixels to be lightened. According to the invention, the position and number of sub-pixels to be lightened in ahigh-resolution display panel are determined according to the distance between the viewer and the display panel, the display panel carries out high-resolution display when the distance is close, and the display panel carries out low-resolution display when the distance is far. The position of the sub-pixels to be lightened in the display panel is designed so as to meet requirements of the human eyes for the resolution and reduce the energy consumption of the display panel at the same time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for driving a display panel and a display device. Background technique [0002] With the development of display technology, people put forward higher and higher requirements for the definition of display panels, therefore, high-resolution display panels are increasingly favored by people. [0003] However, the high-resolution display consumes high energy consumption on the display panel, and the higher the resolution, the higher the demand for the battery life of the display panel. Therefore, how to reduce the energy consumption of the display panel while making reasonable use of the high-resolution display panel It is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The present invention provides a display panel driving method and a display device, which are used to solve the technical problem of high energy c...
