Abstract

The invention provides a display panel and a display device. The display panel comprises an organic light-emitting structure layer, a touch layer and a driving chip. And a cathode is arranged in the organic light-emitting structure layer. The touch layer is arranged above the organic light-emitting structure layer. The touch layer is provided with a plurality of touch electrodes and a plurality oftouch signal lines. The touch electrodes are arranged on the cathode in an array mode, and coupling capacitance is formed between the touch electrodes and the cathode. One end of the touch signal line is electrically connected with the touch electrode. The driving chip is arranged on one side of the display panel.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a display panel and a display device. Background technique [0002] Since OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology came out, it has many advantages, such as low energy consumption, wide viewing angle, wide color gamut, and thin thickness, compared with LCD (Liquid Crystal Display, liquid crystal display) screens. gained rapid popularity. At present, the touch technology with OLED display technology mainly includes the external touch film bonding solution and the On-Cell technology that directly manufactures the touch layer on the film packaging layer. [0003] Among them, because On-Cell technology does not require an external substrate, a layer of OCA (optical adhesive) and touch substrate are removed, which effectively reduces the thickness of the module and saves material costs. Compared with the external touch technology, it has sign...
