Problems solved by technology

The material of the touch electrode is mostly indium tin oxide, etc., and the storage capacity of indium element as a rare earth element in nature is relatively low and expensive
At the same time, the electrode layer of indium tin oxide generally adopts a photolithography process, which greatly increases the manufacturing cost of the touch panel. In addition, the high-temperature annealing process of indium tin oxide limits the use of low-temperature processes.
Thirdly, the conductive electrodes formed by indium tin oxide materials are very fragile and have poor flexibility, so they are not suitable for use on curved surfaces or flexible touch screens.

Abstract

The invention provides a flexible touch display panel which comprises a flexible substrate, a driving device layer, a luminous unit layer, a packaging layer and a touch layer arranged on the packaging layer. The touch layer comprises multiple first touch electrodes and multiple second touch electrodes and multiple second touch electrodes, which are arranged on one side, away from a flexible substrate, of the packaging layer and positioned on a same layer, the first touch electrodes comprise multiple first touch electrode blocks and first connecting portions connecting two adjacent first touch electrode blocks, and the second touch electrodes comprise multiple second touch electrode blocks and second connecting portions connecting two adjacent second touch electrode blocks; the first connecting portions and the second connecting portions are overlapped in a direction perpendicular to the flexible substrate, and each of the first touch electrodes, the second touch electrodes, the first connecting portions and the second connecting portions is made of an electroconductive high-polymer material and formed by means of ink jet printing or film coating.

Description

technical field [0001] The present invention relates to the display field, in particular to a flexible touch display panel and a flexible touch display device. Background technique [0002] At present, in order to realize a touch function in a flexible display panel using an OLED (Organic Light Emitting Diode), a touch electrode is usually formed on one side of the OLED. Most touch electrodes are made of indium tin oxide, etc., and indium, as a rare earth element, has relatively low storage capacity in nature and is expensive. At the same time, the ITO electrode layer generally adopts a photolithography process, which greatly increases the manufacturing cost of the touch panel. In addition, the high-temperature annealing process of ITO limits the use of low-temperature processes. Thirdly, the conductive electrodes formed by indium tin oxide materials are very fragile and have poor flexibility, so they are not suitable for use on curved surfaces or flexible touch screens. ...
