Embodiment 1

[0026] An embodiment of the present invention provides an array substrate, including a display area 100 and a test area 200 , wherein the test area 200 is located at the periphery of the display area 100 .

[0027] A set of test lines 10 and at least two sets of test terminals are arranged in the test area 200 , including at least one set of array (Array) test terminals 20 and at least one set of substrate (Cell) test terminals 30 . In this embodiment, there are two groups of array test terminals 20 and substrate test terminals 30 . Each test terminal in each group of test terminals is connected to each test line in the test circuit respectively.

[0028] In this embodiment, one test line in the test circuit 10 is a common electrode line, which is used for testing the common metal line and the common electrode. The common electrode line is connected to the common electrode line terminal 21 in the array test terminal 20 and also connected to the common electrode line terminal ...

Embodiment 2

[0036] Such as image 3 As shown, the array substrate provided by the embodiment of the present invention is basically the same as the first embodiment, and the array substrate includes a display area 100 and a test area 200 , wherein the test area 200 is located at the periphery of the display area 100 .

[0037] The difference between this embodiment and the first embodiment is that, in this embodiment, only one set of array test terminals 20 and one set of substrate test terminals 30 are provided on the left side of the test line 10 . Include red signal line, green signal line, blue signal line, odd-numbered scan line, even-numbered scan line and common electrode line in the test line 10 and altogether six test lines, respectively with the red signal line terminal 26 in the array test terminal 20, the green signal line Line terminal 25, blue signal line terminal 24, odd-numbered scanning line terminal 23, even-numbered scanning line terminal 22 are connected to common elect...

Abstract

The invention discloses an array substrate and a display device, belongs to the technical of display and solves the technical problem that the existing technology can easily cause static electricity damage to test lines. The array substrate comprises a display area and a test area, wherein a group of test lines and at least two groups of test terminals are arranged in the test area; each test terminal in each group of test terminals is correspondingly connected with the corresponding test line in the group of test lines; one of the test lines is the common electrode line and is used for testing of public metal lines and common electrodes. The invention can be applied to display devices such as liquid crystal display televisions, liquid crystal displays, mobile phones and tablet personal computers.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate and a display device. Background technique [0002] With the development of display technologies, liquid crystal displays have become the most common display devices. [0003] The center of the liquid crystal display is a display area, and a test area is arranged around the display area. Several test terminals and test lines are arranged in the test area, and the liquid crystal display can be tested for defects by inserting probes on the test terminals. [0004] Different test terminals are used to test different components in the liquid crystal display. The current test terminals are used to test components including red signal lines, green signal lines, blue signal lines, odd scanning lines, even scanning lines, and array substrates. common metal wires, common electrodes on the color filter substrate, etc. Wherein, each component is corresponding...
