Display panel and display device

Abstract

The invention provides a display panel. The panel comprises a display area and a non-display area, an under-layer substrate, a plurality of thin film transistors, a plurality of touch control signal wires, a first test signal wire area, an array substrate row driving circuit, a second test signal wire area and a grounding wire area which are located on two sides of the display area; insulating layers are arranged between the thin film transistors and the touch control signal wires; the thin film transistors comprise grid electrodes, grid electrode insulating layers, source electrodes and drain electrodes; the non-display area comprises a first side edge and a second side edge; the first test signal wire area comprises a first side and a second side; the first side is adjacent to the first side edge, a first gap is formed in the portion between the array substrate row driving circuit and the first test signal wire area, a second gap is formed in the portion between the array substrate row driving circuit and the second test signal wire area, a third gap is formed in the portion between the grounding wire area and the second side edge, and the orthographic projection portion of the grounding wire area on the under-layer substrate is partly located in the projection of the second test signal wire area on the under-layer substrate. The invention further provides a display device.

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] In the current lighting and display fields, due to the high mobility of Low Temperature Poly-Silicon (LIPS), more and more researches are widely used in the development of lighting products and panel industries to achieve ultra-narrow borders. industry needs. [0003] For display panels with ultra-narrow bezels, the ability to resist static electricity is an important factor for testing the quality of the display panel. In the current display panel industry, the driving signal is wrapped in the loop formed by the ground wire mainly by adding a circle of ground wire around the panel. When the anti-static ability of the panel is tested, the static electricity will be absorbed by the ground wire ring. However, because the anti-static shock ability is proportional to the distance between the ground wire an...

Problems solved by technology

In the current display panel industry, the driving signal is wrapped in the loop formed by the ground wire mainly by adding a circle of ground wire around the panel. When the anti-static ability of the panel is tested, the static electricity will be absorbed by the ground wire ring. However, because the anti-static shock ability is proportional to the distance between the ground wire and the panel border, the width of the ground wire, and the distance between the ground wire and the signal, the design of the ultra-narrow bezel will lead to the narrower development of the width of the three , which greatly reduces the anti-static ability of the panel
