Problems solved by technology

[0003] However, the exposed test terminals are exposed to the environment and are easily corroded by water vapor in the environment, and once the metal layer in the test terminals is corroded, the corrosion is continuous, which will make the entire test line unusable, and more What's more, it will lead to the corrosion of the test wiring and lead to the scrapping of the display panel as a whole

Embodiment 1

[0034] Such as figure 1 As shown, as the first embodiment of the present application, a schematic diagram of a display panel 10 is disclosed, including a plurality of test lines 200 and a plurality of test terminals 100, a plurality of test terminals 100 and a plurality of test lines The lines 200 are connected in one-to-one correspondence. The test lines 200 are connected to the driving lines 300 inside the display panel 10. The driving lines 300 may include data lines, scanning lines, gate driving lines, source driving lines, and clock signals. line etc. It should be noted that the main improvement of this application lies in the structure of the test terminal 100, and the test terminal 100 is not limited to the connection of the test wiring 200, and the corresponding wiring inside the display panel 10 that needs to be connected to the test terminal 100 is applicable, which belongs to this application scope of protection. The test terminal 100 will be used for specific des...

Embodiment 2

[0058] Such as Figure 9 As mentioned above, as the second embodiment of the present application, the difference from the previous embodiment is that the position of the connecting electrode layer 131 is different, Figure 9 shows a schematic diagram of the corrosion of the test wiring 200 and the test terminal 100, Figure 10 show Figure 9 A schematic cross-sectional view along the C-C cutting line 150.

[0059] The connecting electrode layer 131 is disposed under the first metal pad 111 and the second metal pad 112 corresponding to the discontinuity portion 115; the corrosion-resistant conductive material includes indium tin oxide material, the The test connection wires are made of indium tin oxide material. The test terminal 100 also includes an insulating layer 120 and a transparent conductive layer 130, the insulating layer 120 is disposed on the metal layer 110, and between the first metal pad 111 and the second metal pad 112 Separated by the insulating layer 120, t...

Abstract

The present application discloses a display panel and its test terminals. The display panel includes test wires and test terminals. The test wires are connected to the test terminals. The test terminals include: a metal layer and a connection electrode layer. The metal layer includes a first metal pad and a second metal pad, the first metal pad is connected to the test wiring, and the second metal pad is arranged on the first metal pad away from the test One side of the wiring; the first metal pad is disconnected from the second metal pad through a discontinuity; the connecting electrode layer is electrically connected to the first metal pad and the second metal pad, The connecting electrode layer is made of corrosion-resistant conductive material. The present application improves the anti-corrosion performance of the test terminals of the display panel through the above solution.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a test terminal thereof. Background technique [0002] The manufacturing process of the display panel is often more complicated. Taking the liquid crystal display panel as an example, it includes the array substrate manufacturing process, the color film substrate manufacturing process, the box alignment process, and also includes the cutting process. Cutting a large display panel motherboard into multiple display panel sub-boards. Due to the process yield, certain inspections are required after each key process step to ensure the normal progress of the subsequent process. Here, the wiring process of the array substrate is taken as an example. The driving lines on the array substrate, such as scanning lines, Signal lines such as data lines need to be detected for problems such as poor manufacturing processes such as disconnection. At this time, the...
