[0051] combine Figures 1 to 3 As shown, the present application proposes an array substrate 1. The array substrate 1 has a display area 11 and a non-display area 12 surrounding the display area 11. A test electrode 13 is provided in the non-display area 12. The test electrode 13 is used for Input a test signal into the display area 11, the array substrate 1 includes a spacer 14, the spacer 14 is arranged in the non-display area 12, and is at least partly located above the test electrode 13, and the spacer 14 is provided with probes for detection 4 through the escape channel 14a, the avoidance channel 14a runs through the spacer 14 and extends to the test electrode 13.

[0052] In this example, if figure 1 As shown, the display area 11 of the array substrate 1 is located in the middle of the array substrate 1 , and the non-display area 12 of the array substrate 1 is arranged around the display area 11 of the array substrate 1 . The display area 11 of the array substrate 1 ca...

[0075] The present application also proposes a display device, such as Figure 11 As shown, the display device includes a backlight module 3 and the display panel in the previous embodiment. The backlight module 3 is located on the side of the array substrate 1 of the display panel facing away from the color filter substrate 2 of the display panel, and is used to provide Provide a light source.

[0076] In this embodiment, the backlight module 3 can be a direct-type backlight module 3 or an edge-type backlight module 3, and the backlight module 3 can include a light-adjusting film such as a diffusion sheet, a backplane, a light source, a light guide plate, and other structures. The light emitting side of the backlight module 3 is set towards the array substrate 1 of the display panel, so that the backlight module 3 can provide light source to the display panel, so that the display panel can control the transmission of light and finally display images. Wherein, the specific st...

Abstract

The invention relates to the technical field of display technologies, and discloses an array substrate, a display panel and a display device.The array substrate is provided with a display area and a non-display area annularly arranged on the periphery of the display area, a test electrode is arranged in the non-display area and used for inputting a test signal into the display area, and the array substrate comprises a spacer; the spacer is arranged in the non-display area, at least part of the spacer is located above the test electrode, the spacer is provided with an avoiding channel for the detection probe to pass through, and the avoiding channel penetrates through the spacer and extends towards the test electrode. According to the array substrate provided by the invention, the detection probe can conveniently carry out signal anomaly detection on the array substrate.

Description

technical field [0001] The present application relates to the technical field of display technology, and in particular to an array substrate, a display panel and a display device. Background technique [0002] GOA (Gate driver on Array) is a technology that sets the scanning line driver in the non-display area of ​​the array substrate. POA (PS on Array) technology is a technology that makes spacers PS (Photo Spacer) on the array substrate. The two The technology is widely used due to the advantages of low cost, low power consumption, and narrow borders. When the signal of the display panel made by GOA technology is abnormal, it is necessary to cut off a small piece of the color filter substrate to expose the test electrode on the top layer of the GOA production area of ​​the array substrate, and then use the detection probe to poke the corresponding signal point on the test electrode. , so as to obtain the cause of the signal exception. [0003] In the related art, because...
