Abstract

The present invention provides a touch display panel and a touch display apparatus. The touch display panel includes a substrate, a light-blocking matrix layer and a sensing circuit. The sensing circuit is disposed on a surface of the substrate and forms a single-layer structure and located at a projection of the light-blocking matrix layer. The sensing circuit includes a plurality of driving electrodes, a plurality of sensing electrodes and a plurality of signal wires. The driving electrodes and the sensing electrodes are insulated from each other. The signal wires are connected to the driving electrodes and the sensing electrodes. The sensing electrodes, the driving electrodes and the signal wires are disposed on the single-layer structure. In the touch display panel and the touch display apparatus of the invention, the single-layer sensing circuit having the mesh electrodes, for example the driving electrodes and the sensing electrodes, is formed at the light-blocking matix layer of the touch display panel, so the setting areas of the mesh electrodes can be increased without increasing the light penetration loss. Therefore, the sensitivity of the touch display panel and apparatus can be enhanced, the whole RC loading can be reduced and the entire efficiency can be enhanced.

Description

technical field [0001] The present invention relates to a touch display panel and a touch display device, in particular to a touch display panel and a touch display device in which sensing circuits are located on the side of a substrate to form a single-layer structure. Background technique [0002] The touch technologies applied to touch display panels are roughly divided into two types: capacitive touch display panel and resistive touch display panel. In recent years, the market share of capacitive touch display panel has gradually grown, and it has the opportunity to surpass resistive touch display panel and become the mainstream of the market. technology. Capacitive sensing touch uses changing the capacitance of the panel to cause a current change, which is then converted into a potential change to determine the user's touch coordinates. [0003] Among them, the capacitive touch display panel can be further subdivided into a single-layer capacitive touch display panel a...
