Abstract

The invention relates to a touch control display panel, which comprises a substrate, a light shielding matrix layer and a sensing circuit, wherein the sensing circuit is positioned on one side surface of the substrate to form a single layer structure, is positioned in a vertical projection part of the light shielding matrix layer and comprises a plurality of driving electrodes, a plurality of sensing electrodes and a plurality of conducting wires, in addition, the driving electrodes and the sensing electrodes are mutually insulated and separated, and the conducting wires are respectively connected with each driving electrode and each sensing electrode, wherein the sensing electrodes, the driving electrodes and the conducting wires are all positioned in the single layer. The invention also discloses a touch control display device. The touch control display panel and the touch control display device provided by the invention have the advantages that under the condition of not increasing the light transmission loss, the distribution area of the sensing circuit can be increased, so that the goals of improving the sensitivity of the touch control display panel and the touch control display device, reducing the integral resistance-capacitance load and improving the integral efficiency are achieved.

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 the sensing circuit is located on the side of a substrate to form a single-layer structure. Background technique [0002] The touch technology applied to touch display panels can be 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 market leader. mainstream technology. Capacitive sensing touch is to change 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...
