Abstract

The invention discloses a display panel and a preparation method thereof, and a display device. The display panel comprises: a substrate layer; the metal layer that is arranged on the substrate layer;the interlayer insulating layer that is arranged on the metal layer; the first slotted hole that extends to the surface of the metal layer from one surface, far away from the metal layer, of the interlayer insulating layer, and part of the metal layer is exposed in the first slotted hole; and the touch lead layer that is arranged on the surface of the interlayer insulating layer and is connectedwith the metal layer through the first slotted hole. The phenomenon that the connecting holes are cured in advance due to heat conduction of the touch lead layer in the flat layer thermocuring processis avoided, the fracture resistance of the common electrode layer is further enhanced, and the reliability of the touch function is improved.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In order to realize the integration of liquid crystal display and touch function, in the field of small and medium-sized displays, the common electrode is generally patterned, which is used not only as the common electrode of liquid crystal display, but also as the sensing electrode of touch function, and simultaneously drives the display and touch through time-sharing operations. touch function. [0003] According to the degree of embedding of the sensing electrodes in the liquid crystal panel, it can be divided into On Cell TP technology and In Cell TP technology. Among them, the In Cell TP technology fully embeds the touch function into the LCD pixels, so it has outstanding advantages such as thinness of the whole machine, excellent display effect, and good pe...
