Abstract

The invention discloses a display panel, a preparation method of the display panel and a display device. The display panel comprises a touch layer and a polarization layer which are arranged in a stacked mode. The polarization layer comprises ions, the touch layer comprises a plurality of touch wires, each touch wire comprises a first metal layer and a second metal layer which are stacked, and the first metal layer is adjacent to the polarization layer; wherein the chemical stability of the first metal layer is higher than that of the second metal layer, the second metal layer is provided with at least one groove, and the first metal layer covers the groove. By means of the mode, the corrosion condition of the touch wires can be improved, and the overall performance of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Due to the excellent flexibility of the organic light emitting diode (OLED) display panel, currently the OLED touch display panel has become a favored object of electronic devices such as mobile phones and tablet computers. [0003] However, the inventors have found through long-term research that during the reliability test of the OLED display panel, due to the risk of water vapor intrusion, some substances in the polarizing layer will corrode the touch wiring of the touch layer in the display panel, and Large areas of corrosion and expansion will occur along the touch traces, resulting in breakage of the touch traces or a significant decrease in line resistance, thereby causing failure of the touch control function. Contents of the invention [0004] The technical ...
