Abstract

The invention discloses a display panel and a display device. The display panel comprises a common electrode layer, a power management chip and a time sequence controller. The common electrode layer is configured into N common electrode subareas which are electrically isolated from one another. The power management chip is electrically connected with the common electrode subareas and is used for supplying a feed-in voltage to the common electrode subareas according to a control signal. The time sequence controller is electrically connected with the common electrode subareas and the power management chip, and outputs a corresponding control signal in response to the fact that the feedback voltages of the common electrode subareas exceed an offset range. N is an integer greater than or equalto 2. The common electrode layer is configured into a plurality of common electrode sub-areas, and the feed-in voltage of each common electrode subarea is adjusted according to the feedback voltage of each common electrode sub-area, so that the direct-current voltage in each common electrode sub-area can be kept at a better value, and the residual image problem is weakened or eliminated.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of liquid crystal display technology, and in particular to a display panel and a display device. Background technique [0002] When the LCD monitor displays the same picture for a long time, and then switches the current picture to the next picture, the current picture will remain in the next picture. This phenomenon is called image sticking (IS, Image Sticking), residual image, burn marks, etc. The existence of IS will greatly affect the display quality and effect, resulting in poor customer experience, loss of production yield, and reduced market acceptance of display panels. [0003] IS is one of the long-standing and stubborn issues of LCD (Liquid Crystal Display), involving many factors. If such problems occur, it will take time and effort to troubleshoot and solve them, which will seriously affect the panel production and customs clearance time. Proced...
