Abstract
The invention provides a touch control display panel and a touch control display device. The touch control display panel comprises an array substrate and a color film substrate arranged oppositely; the touch control display panel comprises a display area and a non-display area surrounding the display area; the array substrate side of the display area is provided with touch control electrodes; the color film substrate side of the non-display area is provided with a first black matrix; the array substrate side of the non-display area is provided with a ground lead surrounding the display area; the first black matrix is inside provided with a hollow-out part; the positive projection image of at least a part of the hollow-out part on the array substrate at least partially overlaps the positive projection image of the ground lead on the array substrate, and / or the positive projection image of the at least a part of the hollow-out part on the array substrate is located between the ground lead and the display area. The problem of touch control exceptions caused by coupling of a ground lead and a first black matrix is solved; the stability of the touch control display panel is improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of touch display, and in particular, to a touch display panel and a touch display device. Background technique [0002] In the field of display technology, static electricity is one of the main factors that reduce the yield of display panels. The shielding and protection of static electricity is one of the factors that need to be considered in the design of display panels. Antistatic capability is also the main performance and reliability evaluation of display panels. one of the indicators. Since the circuits and components in the display panel are very fine, as long as there is a slight electrostatic discharge phenomenon, the entire display panel can easily be scrapped. [0003] At present, the main solution for the electrostatic discharge phenomenon is to set a grounding lead around the display area in the non-display area of the display panel, and ground it through an external fle...
