Organic light emitting display panel and device, and manufacturing method

Abstract

The invention discloses an organic light emitting display panel and device, and a manufacturing method. The organic light emitting display panel comprises: an organic light emitting array substrate; a thin film package layer covering the organic light emitting array substrate; a plurality of first touch electrodes and a plurality of second touch electrodes arranged on the same layer; adjacent first touch electrodes in the same column are connected; adjacent second touch electrodes in the same column are disconnected with each other; the thin film package layer comprises a first organic layer and a second organic layer, the first organic layer is provided with a plurality of first groove structures and a plurality of second groove structures; the first touch electrodes are located in the first groove structures, and the second touch electrodes are located in the second groove structures. By adoption of the organic light emitting display panel disclosed by the invention, the smoothness of the thin film package layer is improved, and the reliability of the organic light emitting display panel is improved on the premise of ensuring the thinness and light weight of the organic display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel, a device and a manufacturing method. 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 o...

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 susceptible to corrosion due to the influence of oxygen and water vapor in the environment, and the flatness of the thin-film packaging layer is not good, which will affect the effect of touch control and display
