Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] IS detection is a crucial item in reliability testing of liquid crystal display panels. This test is to detect the IS degree of the LCD panel by observing the display of a certain gray scale (such as L127) after continuously lighting the LCD panel with a specific black and white checkerboard picture for a period of time.

[0022] In the IS detection picture, the voltage of the black area picture and the white area picture are different, ...

Abstract

The invention discloses a colorful filtering substrate and a display panel. The display panel comprises the colorful filtering substrate. The colorful filtering substrate further comprises a substrate, two common electrode areas and at least two common voltage lines, wherein the two common electrode areas are both arranged on the substrate; the two common electrode areas are respectively supplied with voltage by the corresponding common voltage lines; the two common electrode areas are distributed in the form of mutual meshed checkerboard. In such a manner, the display panel has the advantages that the residual image problem of the display panel can be solved, the reliability of the display panel can be promoted, the IS detection problems can be reduced, the repairing rate of the display panel can be reduced and the manpower and material resources can be saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate and a display panel. Background technique [0002] In the liquid crystal manufacturing process, since the liquid crystal cannot be completely purified, it is inevitable that some mobile ions will remain in it. When a voltage is applied, these mobile ions will be attracted to the electrode by the opposite polarity charge on the electrode. move. When the average value of the applied voltage of the two electrodes is not zero, the ions tend to move towards one of the electrodes and accumulate on the interface between the liquid crystal molecules and the alignment film. After this happens, the accumulated ions inside the liquid crystal will form an internal electric field inside the liquid crystal. This internal electric field and the applied external electric field will affect the ordering of the liquid crystal molecules. Under the action, it becomes diffe...
