Problems solved by technology

[0002] At present, in order to realize the touch function of the flexible display panel using Organic Light Emitting Diode (OLED, Organic Light Emitting Diode), it is usually necessary to attach a layer of touch module on the basis of the display panel, so that the flexible display panel cannot be thinned.
In order to realize the lightness and thinning of the touch-sensitive flexible display panel, the traditional module bonding technology is replaced by the integration technology. The current integration technology mainly integrates the touch electrode on the protective film layer, polarizer or glass For the thin film encapsulation layer, the above method reduces the thickness of the flexible display product to a certain extent, but since the touch electrodes are integrated inside the display panel, the distance between the touch electrodes and the display unit is very small, so the touch electrode signals will be affected by the display signal. Interference, thus affecting the touch accuracy

Abstract

The present invention provides a flexible touch display panel, comprising: a flexible substrate; a light-emitting unit layer arranged on the flexible substrate, the light-emitting unit layer includes a plurality of light-emitting units; a first touch electrode layer, a second touch electrode layer and a set The insulating layer between the first touch electrode layer and the second touch electrode layer, the first touch electrode layer includes a plurality of first touch electrodes insulated from each other, the first touch electrodes are striped along the display panel Extending in the direction of the bending axis; the second touch electrode layer includes a plurality of second touch electrodes insulated from each other. The second touch electrodes extend in a strip shape perpendicular to the direction of the bending axis and are arranged along the direction of the bending axis. The first touch electrode layer is a transparent conductive layer, and the second touch electrode layer is a metal grid. By setting the first touch electrode layer as a transparent conductive layer, the signal interference of the light emitting unit below to the touch electrodes can be shielded, thereby ensuring the touch stability of the flexible touch display panel.
