Abstract

The invention discloses a touch display panel and a touch display device. The touch display panel comprises touch electrode blocks, touch signal lines and suspension electrodes, wherein the suspension electrodes and the touch signal lines are formed in the same layer, and the suspension electrodes are located between every two adjacent subpixels located on an array substrate and correspond to the positions of black matrixes among color stoppers on a color film substrate. Under the situation that no manufacturing step is added, the color cast problem of the touch display panel can be improved. In addition, the width of each touch signal line in the line direction is increased properly, the resistance value of each touch signal line is decreased, the problem that the edge of each touch electrode block is inviable is effectively improved, and the display effect of the touch display panel and the touch display device is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a touch display device thereof. Background technique [0002] With the rapid development of display technology, touch display devices have gradually spread in people's daily life. At present, touch display devices can be divided into: plug-in type, surface-covered type, and built-in type according to the composition structure. Among them, the in-cell (In cell) type touch display device embeds touch electrodes inside the liquid crystal display panel, which can Thinning the overall thickness of the module can greatly reduce the production cost of the touch display device, making it favored by major panel manufacturers. [0003] At present, existing in-cell touch display devices use the principle of mutual capacitance or self-capacitance to detect the position touched by a finger. Among them, using the principle of self-capacitance, a plural...
