Problems solved by technology

[0003] In the prior art, the relatively mature integrated touch display panel is to add a circuit structure with touch detection function to the color filter substrate. However, the integrated touch display panel has difficulties in detecting touch signals and is susceptible to interference from other signals. question

Embodiment Construction

[0020] Please refer to figure 1 , figure 1 It is a schematic top view of the conventional touch display panel 100. The existing touch display panel 100 generally includes a display area (not marked) and a non-display area (not marked) located at the periphery of the display area. figure 1 In the middle, the dotted line 101 is the dividing line between the display area and the non-display area. The existing touch display panel 100 usually also includes a touch layer 106 (please refer to figure 2 ) Defined touch area (not marked), and non-touch area (not marked) located at the periphery of the touch area. figure 1 In the middle, the dotted line 102 is the dividing line between the touch area and the non-touch area. Generally, the touch area surrounds the display area, and the touch area has more area than the display area. therefore, figure 1 Here, the dashed line 102 surrounds the dashed line 101, and the ring-shaped area between the dashed line 102 and the dashed line 101 belo...

Abstract

A touch display panel and a display device, the touch display panel has a display area and a non-display area located on the periphery of the display area, and also includes: a color filter substrate; an array substrate, the array substrate is opposite to the color filter substrate Setting; the touch electrode layer is located on the color filter substrate, the touch electrode layer covers the display area and at least part of the non-display area; the shielding layer is located on the array substrate, and the shielding layer is located The array substrate is disposed in the non-display area and facing the touch electrode layer. In the touch display panel, a shielding layer is provided between the wires and the touch electrode layer, and the wires are shielded by the shielding layer to prevent the wires from interfering with the touch electrode layer and ensure normal touch detection of the touch display panel.

Description

Technical field [0001] The present invention relates to the field of touch display, in particular to a touch display panel and a display device. Background technique [0002] Touch display devices include touch-sensitive liquid crystal display devices and touch-sensitive electronic paper, etc. Initially, the way to realize the touch function is to set up a separate touch panel above the display panel (referred to as "plug-in touch display device") . The externally mounted touch display device requires at least four to five layers of glass and two hard bonding processes, which increase the cost on the one hand, and on the other hand, it also leads to an increase in the thickness of the touch display device and a loss of bonding yield. Therefore, the industry has developed a display panel that directly integrates touch functions, which is called an integrated touch display panel. [0003] In the prior art, the more mature integrated touch display panel adds a circuit structure with...
