Drive method of display panel and display device

Abstract

The embodiment of the invention provides a drive method of a display panel and a display device, relating to the technical field of display, for achieving the purpose that bad influences generated tothe display device by the normally turned-on pixels are avoided under the premise that power consumption is saved. The drive method of the display panel comprises the following steps: when the displaypanel is under the target work pattern, issuing a target pattern control instruction; under the effects of the target pattern control instruction, at each display time period, providing scanning signals for grid lines of a target display area in a separate time manner, and when each grid line receives the scanning signal, providing data signals for data lines of the target display area; at different display time periods, the data signals provided for the data lines are different, within one display time period, providing first data signals corresponding to the first highest gray scale numberfor the data lines, and at another display time period, providing second data signals corresponding to the first lowest gray scale number for the data lines. The drive method of the display panel is used for driving the target display area to display a 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, ...

AI Technical Summary

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
