Problems solved by technology

Since this structure is only suitable for making rigid AMOLED displays, and the overall thickness of the product is relatively thick, it is not suitable for the current development direction of thinner and lighter products.
[0004] In addition, when the touch sensing circuit is made on the (Thin Film Encapsulation; TFE) thin film encapsulation layer of the AMOLED display, since the touch sensor (touch sensor) is very close to the TFT layer, it is very easy to be interfered by the TFT scanning signal, such as generating Signal interference such as noise (noise) causes the touch function to fail to work normally and effectively

Abstract

A touch display panel and a manufacturing method therefor, and a touch display device. The touch display panel comprises a flexible substrate and a metal grid touch electrode layer. The metal grid touch electrode layer is disposed on the flexible substrate, and the metal grid touch electrode layer is provided with multiple driving electrodes and multiple sensing electrodes. Multiple floating electrodes spaced from one another are disposed in each driving electrode and each sensing electrode, the floating electrodes are insulated from the driving electrodes and the sensing electrodes, and the floating electrodes, the driving electrodes, and the sensing electrodes are disposed on the same layer. Therefore, an interference signal of an OLED layer is shielded and dispersed, so that the touch sensitivity is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel, a manufacturing method thereof, and a touch display device. Background technique [0002] In recent years, the active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode; AMOLED) display technology has developed rapidly, and the corresponding touch control scheme has also been followed up simultaneously. Currently, the touch technologies used with AMOLED displays mainly include add-on type (Add on Type) touch film bonding technology and glass encapsulation (On-Cell) technology. Whether it is the plug-in or glass packaging technology, there is a problem of increasing the thickness of the product and affecting the design of the narrow frame. [0003] The external touch film lamination technology uses optical clear adhesive (Optical Clear Adhesive; OCA) to bond the touch film and the AMOLED display together. Depending on ...
