Abstract

The embodiment of the invention provides a display panel and a display device, and belongs to the technical field of display, the display panel comprises a substrate, a touch control wire, a signal wire, a packaging layer and a blocking part arranged in a non-display area, the blocking part comprises a first blocking part and a second blocking part, and the packaging layer covers the first blocking part and at least extends to the position between the first blocking part and the second blocking part; the substrate comprises via holes, the via holes are located in the side, away from the display area, of the edge of the packaging layer, orthographic projections of the via holes and the packaging layer on the substrate are not overlapped, and at least part of the touch wires are electricallyconnected with the signal wires through the via holes; the implementation difficulty of the via hole process is reduced, short circuits caused by photoresist residues between the adjacent touch control wires are reduced, the quality of the display panel is improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic light-emitting diode (OLED) devices have the advantages of simple structure, fast response, active light emission, and low power consumption. They have been widely used in the display field in mobile phones, tablets, and TVs. The screen touch technology has also undergone iterative development. At present, an external touch unit is generally used. However, in order to reduce the overall thickness of the display panel, a touch unit integrated inside the panel has been developed, that is, the touch circuit is directly built into the display panel. on the packaging film. [0003] The above-mentioned in-cell touch display panel contains more touch electrodes, and more touch traces are arranged in the non-display area of ​​the display panel to electrically connect with the touch electrodes. The orga...
