Abstract
The invention discloses a display panel and a display device.The display panel comprises a flat panel display area and frame display areas located on the two sides of the flat panel display area, and the display panel comprises a display function layer and a touch function layer arranged on the display function layer; the touch function layer comprises a plurality of touch sensing electrodes distributed in the flat panel display area in an array manner and a plurality of pressure sensing electrodes distributed in the frame display area; the display function layer comprises a substrate, and a light-emitting layer, a cathode layer and a thin film packaging layer which are sequentially arranged on the substrate, and the touch function layer is arranged on the thin film packaging layer; the thin film packaging layer is provided with a plurality of grooves in one-to-one correspondence with the pressure sensing electrodes, the display function layer further comprises a plurality of pressure sensing parts in one-to-one correspondence with the grooves, the pressure sensing parts are arranged in the grooves, and the two ends of the pressure sensing parts are electrically connected to the pressure sensing electrodes and the cathode layer respectively. The cathode layer is reused, so that the technological process is simplified, and the cost is reduced; and meanwhile, edge mistaken touch is avoided.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of the full-screen mobile phone market, the waterfall screen, as a technology with great development potential, has become the direction for major mobile phone manufacturers to compete for development. Compared with the traditional screen, the waterfall screen has a curved display area at the mobile phone frame, which is extremely It greatly reduces the visual impact of the black frame on the edge of the traditional OLED screen, making the display more full and beautiful. However, for this kind of waterfall screen, there is no space for the original physical buttons (start button / volume button) on the left and right borders. [0003] In the prior art, the buttons used on the left and right borders are pressure-sensitive schemes—relying on the linear motor and pressure sensor insid...
