Problems solved by technology

Regarding the above technical solution, the inventors have found at least the following technical problems: For example, the dual-channel Tx can generally test the open circuit and short circuit of the Tx channel through probes, while the single-channel Rx can only use probes to test the short circuit. It is not possible to test the open circuit of the Rx channel, so that the open circuit of the Rx channel cannot be monitored during the process, and there is a risk of batch failure

Abstract

The embodiment of the invention relates to a touch display substrate and a testing method and a manufacturing method thereof. The touch display substrate comprises a substrate body and a touch electrode layer arranged on the substrate body, the touch electrode layer comprises a plurality of touch driving electrodes, a first electrode wire is led out from each of the two ends of each touch drivingelectrode, and each first electrode wire is connected to a binding area of the touch display substrate body; the touch sensing electrodes and the touch driving electrodes are arranged in a crossed andinsulated mode, a second electrode wire is led out from one end of each touch sensing electrode and connected to the binding area of the touch display substrate, and a third electrode wire is led outfrom the other end of each touch sensing electrode and connected with a test block; the test block is used for testing an open circuit. According to the embodiment of the invention, the short circuitof the touch sensing electrode channel can be tested, and the open circuit of the touch sensing electrode channel can also be tested, so that the manufacturing yield of the touch display substrate isimproved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, in particular to a touch display substrate, a testing method, and a manufacturing method thereof. Background technique [0002] An OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display with a touch function mainly includes an In cell structure and an On cell structure. The In cell structure refers to placing the touch display substrate under the upper substrate of the display panel, while the On cell structure refers to placing the touch display substrate on the upper substrate of the display panel. [0003] In related technologies, due to the narrow frame design requirements for the On Cell structure of the OLED display, the touch display substrate generally adopts a design scheme of dual channels of Tx (touch driving electrodes) and single channel of Rx (touch sensing electrodes). Regarding the above technical solution, the inventors have found ...
