Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate, and a gate driving circuit, a pressure sensor and a first shielding retaining wall positioned on the substrate, and the first shielding retaining wall is positioned between the gate driving circuit and the pressure sensor, and is connected to a first fixed potential. The first shielding retainingwall has an electromagnetic shielding function, so that the first shielding retaining wall can shield display signals in the gate driving circuit from interfering in the pressure sensor and pressure sensing signals in the pressure sensor from interfering in the gate driving circuit, and thus, normal work of the gate driving circuit and the pressure sensor is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, the application of display panels is becoming more and more extensive, and the requirements of users for the functions and appearance of display panels are also becoming more and more diverse. In order to meet the needs of users, flexible display panels have emerged. Based on the deformable and bendable characteristics of the flexible display panel, a pressure sensor is installed on the frame of the flexible display panel to detect the pressure value of the flexible display panel through the pressure sensor, so as to avoid damage to the flexible display panel due to excessive pressure value. However, in the existing display panel, the display signal and the like will cause strong interference to the pressure-sensing signal of the pressure s...
