Problems solved by technology

Among them, the color film layer array substrate side is provided with a color film layer and a black matrix (Black Matrix), and the color film layer and the black matrix are doped with resins of various pigments, which makes it easier to introduce ion impurities into the TFT-LCD. At present, the main method is to optimize the composition of liquid crystal and CF to reduce ionic impurities, but the improvement effect is not obvious

Abstract

The application provides a display panel and a touch display device. Since a conductive layer covered by a black matrix layer is provided in the display panel and the conductive layer is electricallyconnected to a common electrode or a ground line to derive charges of ions accumulated in the color filter substrate, the afterimage problem during the display of the display panel and the touch display device is avoided. In addition, the conductive layer located in the display panel can reduce the influence on the touch performance of the touch display device.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a touch display device. Background technique [0002] In recent years, since Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has lower operating voltage, lower power consumption and lower With advantages such as space occupation, it has become the mainstream display in the market. However, when people require the display to have better performance such as high brightness, high contrast and high response time for better display, problems such as uneven brightness (Mura) and image sticking of the display (Image Sticking) need to be solved urgently. The afterimage problem will seriously affect the picture quality of TFT-LCD. [0003] For TFT-LCD, when the screen that needs to be displayed for a long time is switched to the next screen, the displayed screen will still appear in the next screen, and the phenomenon that occurs when this kind of di...
