An organic light emitting display panel

Abstract

The invention discloses an organic light-emitting display panel, which comprises: an organic light-emitting element array substrate and a thin film encapsulation layer covering it; a plurality of touch driving electrodes and touch sensing electrodes; a plurality of first touch wiring lines and a second touch sensing electrode. Two touch traces, the first touch trace is electrically connected to the corresponding touch driving electrode; the second touch trace is electrically connected to the corresponding touch sensing electrode; the thin film encapsulation layer includes a first organic layer and a second Organic layer; the first organic layer is provided with a plurality of first grooves and a plurality of second grooves, and the second organic layer is provided with a plurality of third grooves and a plurality of fourth grooves; the touch driving electrodes are located in the first In the groove, the first touch wiring is located in the second groove; the touch sensing electrode is located in the third groove, and the second touch wiring is located in the fourth groove; a plurality of first touch wiring and the second touch trace are located in the thin film encapsulation layer. The invention provides an organic light-emitting display panel, which is used to meet the requirement that the touch wires are not easily corroded.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to an organic light emitting display panel. Background technique [0002] With the rapid development of display technology, breakthroughs have been made in both the size of the display screen and the display quality. As an important development direction of display technology, flexible display devices have attracted much attention due to their thinness and flexibility. The touch-sensitive flexible display panel combines the advantages of touch technology and flexible display technology. It not only has the characteristics of changeable shape or bendability, but also can be directly operated by users with fingers or stylus, which is very comfortable and convenient. Therefore, it has been favored by people. s concern. [0003] At present, most of the touch electrodes of the touch-sensitive flexible display panel are externally attached or integrated into t...

AI Technical Summary

Problems solved by technology

[0004] 1. Attaching the touch module to the flexible display panel, this method often cannot realize the thinning of the touch-sensitive flexible display panel

[0005] 2. Integrate the touch electrodes on the protective film layer, polarizer or cover plate. Although this method can reduce the thickness of the touch-sensitive flexible display panel to a certain extent, it is harmful to the thickness of the protective film layer, polarizer plate and cover plate. Production requirements are higher

[0006] Moreover, when the above-mentioned touch-sensitive flexible display panel is bent, cracks are likely to occur on the surface, and the cracks are easy to extend and expand, so that the touch-control electrodes are likely to break, resulting in failure of the touch-control function.

In addition, the touch traces connected to the touch electrodes are easily corroded by the influence of oxygen and water vapor in the environment, which affects the effect of touch control and display
