Problems solved by technology

However, when the performance of the display panel needs to be tested after the display panel is prepared, the short-connected parts of the above-mentioned multiple wires should be disconnected. At this time, when the laser is used to cut the wires along the edge of the display panel, the wires will melt and splash , after the test probes are pressed onto the test pads, the test probes are likely to be in electrical contact with the molten and spattered wires, which can easily lead to a short circuit between adjacent test pads or adjacent test probes, thereby causing The signals interfere with each other, and even burn the test pad due to short circuit, which affects the test of the performance of the display panel

Abstract

The embodiment of the invention discloses a display substrate, a display panel and a display device. The display substrate comprises at least two test bonding pads which extend in a first direction and are distributed in a second direction, and multiple anti-static wires extending along the second direction to a first edge of the display substrate, wherein the second direction intersects with the first direction, and the anti-static wires are electrically connected with the test bonding pads correspondingly. Influences of molten and splashed wires on a testing unit are reduced, and the reliability of the testing unit is improved.

Description

Technical field [0001] The embodiments of the present invention relate to display technology, and in particular, to a display substrate, a display panel, and a display device. Background technique [0002] During the manufacturing process of the organic light emitting diode display panel or the liquid crystal display panel, after the display panel is prepared, the performance of the display panel needs to be tested. In the existing display panel design, in order to facilitate testing and good product screening, a test unit is generally set on the display substrate (such as an array substrate) of the display panel, and the performance test of the display panel is performed by inputting test signals to the test unit. [0003] Generally, the test unit includes a plurality of test pads arranged on the peripheral circuit area of ​​the array substrate. In the manufacturing process of the display panel, in order to prevent the generated static electricity from damaging the test pads, the ...
