Problems solved by technology

In this way, although pixel aging can be avoided, if the position of displaying the target picture is to be moved within the entire display screen, the grid scanning unit must provide scanning signals to the grid lines corresponding to different areas at regular intervals, which requires the entire The grid scanning units are all in the working state, thus increasing unnecessary power consumption

Abstract

Embodiments of the present invention provide a method for driving a display panel and a display device, which relate to the field of display technology, and avoid adverse effects on the display device caused by constant bright pixels on the premise of saving power consumption. The driving method of the display panel includes: when the display panel is in the target working mode, issuing a target mode control command; under the action of the target mode control command, in each display period, providing scanning signals to the grid lines of the target display area in time division, When each gate line receives a scanning signal, it provides data signals to the data lines in the target display area; in different display periods, the data signals provided to the data lines are different, and within a display period, the data lines corresponding to the target data lines are provided. The first data signal with the highest gray scale number is used to provide the data line with the second data signal corresponding to the first lowest gray scale number during another display period. The above driving method of the display panel is used to drive the target display area to display the target picture.

Description

【Technical field】 [0001] The present 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] When the display device is in a specific working mode, some areas of the display screen will display the target image for a long time. Such as figure 1 As shown, when the display device is in the standby state, in order to enable the user to know the clock information in real time without unlocking it, the digital clock information 1 is usually displayed in the middle area of ​​the display screen. Or, in order to conform to the development trend of the full screen, many display devices currently adopt the design of virtual buttons. lower area. However, when the display device is in the above working mode, in order to display images in some areas for a long time, the pixels corresponding to these areas need to be kept in a constant bright state, which will lead to pixel aging, ...
