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 present invention provides a flexible touch display panel, comprising: a flexible substrate; a driving device layer; a light-emitting unit layer; a packaging layer; A layer away from the multiple first touch electrodes and multiple second touch electrodes on the side of the flexible substrate, the first touch electrodes and the second touch electrodes are located on the same layer, wherein the first touch electrodes A touch electrode includes a plurality of first touch electrode blocks and a first connecting portion connecting two adjacent first touch electrode blocks, and the second touch electrode includes a plurality of second touch electrode blocks and a second connection portion connecting two adjacent second touch electrode blocks; the first connection portion and the second connection portion overlap the first touch electrode in a direction perpendicular to the flexible substrate . The second touch electrodes, the first connection part and the second connection part are all made of conductive polymer materials, and formed by inkjet 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. ...
