Problems solved by technology

[0003] The display panel is usually provided with a display area and a frame area surrounding the display area. Circuit components and signal traces are arranged in the frame area, and the cut-off ends of some signal traces are also set in the frame area. When affected, the cut-off end of the signal trace is more susceptible to the influence of static electricity, and the static electricity is easily coupled into the display area to cause damage to the devices in the display area, affecting the normal display or touch function of the display panel

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display, the display panel comprises a first touch electrode and a second touch electrode arranged in a display area; first touch signal lines which are electrically connected with the first touch electrodes, second touch signal lines which are electrically connected with the second touch electrodes, and at least one first touch signal line and at least one second touch signal line are adjacent to each other in the non-display area; signal protection lines which are arranged in the non-display area and located between the first touch signal lines and the second touch signal lines which are adjacent to each other; the signal protection line comprises a first end part and a second end part, the first end part is connected with a first fixed level signal, and the second end part is a cut-off end; signal shielding lines which are located between the signal protection lines and the touch electrodes adjacent to the signal protection lines, the signal shielding lines are arranged in a floating mode, and the signal shielding lines and the second ends of the signal protection lines are overlapped in the direction that the signal shielding lines point to the signal protection lines. Therefore, the antistatic performance can be improved.

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] From the era of CRT (Cathode Ray Tube, cathode ray tube) to the era of liquid crystal, and now to the era of OLED (Organic Light-Emitting Diode, organic light-emitting diode), the display industry has experienced decades of development and has become ever-changing. The display industry is already closely related to our lives. From traditional mobile phones, tablets, TVs and PCs to current electronic devices such as smart wearable devices and VR, display technology is inseparable. [0003] The display panel is usually provided with a display area and a frame area surrounding the display area. Circuit components and signal traces are arranged in the frame area, and the cut-off ends of some signal traces are also set in the frame area. When affected, the cut-off end of the signal line is more easi...
