Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. In the drawings, for clarity and ease of understanding and description, the size and thickness of the components shown in the drawings are not in scale.

[0023] Such as figure 1 As shown, it is a schematic diagram of the basic structure of the touch display panel provided by the embodiment of the present invention. The touch display panel includes a display area A1 and a non-display area A2 located on the side of the display area A1. Since the embodiment of the present invention mainly It is an improvement for the non-display area A2, so the structure in the display area A1 is not the focus of the embodiment of the present invention, and the detailed description of the display area A1 will not be given here. A plurality of binding units 10, a plurality of driving chips 102 and...

Abstract

The invention provides a touch display panel and a touch display device. The touch display panel comprises a display area and a non-display area located on one side of the display area, a plurality of binding units, a plurality of driving chips and a plurality of touch test units are arranged in the non-display area, and each binding unit comprises at least one binding area. Each driving chip is arranged corresponding to one binding area and is electrically connected with the binding area, and each touch test unit is arranged adjacent to one binding unit and is electrically connected with the binding area in the binding unit. According to the invention, the plurality of binding units and the plurality of touch test units are arranged, and each touch test unit is electrically connected with the binding area in the binding unit adjacent to the touch test unit, so that the wiring distance between the touch test unit and the binding area can be shortened, the wiring span is reduced, the wiring difficulty is reduced, and the process production is facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] With the rapid development of the communication industry, people's demand for mobile phones, TVs, tablets, computers, digital cameras and other electronic products is increasing, and various display devices are also developing in the direction of larger size and bendability. At present, the touch function of the medium-sized (8-20 inches) display panel in the industry is realized by using an external touch screen, that is, the touch layer is made separately, and then the touch layer is combined with the display panel. However, the thickness of the external touch screen is too thick to be easily folded, and it is not suitable for a foldable medium-sized display panel. DOT (Direct On-cell Touch, directly prepare the touch circuit on the display panel) The touch circuit of the display panel is ...
