Problems solved by technology

[0002] At present, in order to realize the touch function of the flexible display panel using organic light-emitting diodes, 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 traces of the touch electrodes will cross the frame area inside the display panel and climb repeatedly. Slope crossing may easily lead to disconnection of the wiring of the touch electrode, thereby causing poor touch control and affecting the realization of the touch function of the touch display panel

Abstract

The invention provides a touch control display panel. The touch control display panel comprises a substrate, a thin film transistor array, an organic light emitting unit, a thin film packaging layer and a touch sensing electrode, wherein the thin film transistor array, the organic light emitting unit and the thin film packaging layer are sequentially stacked on the substrate, and the touch sensing electrode is arranged on the side, away from the organic light emitting unit, of the thin film packaging layer. The touch control display panel comprises a display area and a non-display area surrounding the display area. The non-display area is provided with a first dam surrounding the display area, and a second dam surrounding the first dam. The non-display area comprises a binding area and frame areas located on the two sides of the binding area, and at least the binding area, the portion between the first dam and the second dam and the side, close to the display area, of the first dam are filled with organic materials. Touch control electrode lead breakage caused when the touch control electrode leads pass through uneven dam areas is avoided. Besides, the organic materials have good elasticity, can relieve and protect stress accumulation of the touch control electrode leads when the display panel is bent. The provided touch control display panel is more applicable to flexible display.
