Abstract

The embodiment of the invention provides an array substrate, a display panel, a display device, a large substrate and a test method, and relates to the technical field of display equipment. By means of the array substrate, the display panel, the display device, the large substrate and the test method, the occupying space of a test circuit is reduced, and the short-circuit problem caused by damage of a test switch is avoided. The array substrate comprises multiple signal lines, and the end, close to a first edge of the array substrate, of each signal line is connected to the first edge of the array substrate through a first lead; the array substrate further comprises at least one contact terminal and multiple second leads; one ends of the second leads are connected to the contact terminals, and the other ends of the second leads are connected to a second edge of the array substrate; the first edge and the second edge are oppositely arranged. The array substrate is applicable to the display device.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of display equipment, in particular to an array substrate, a display panel, a display device, a large board and a testing method. [0003] 【Background technique】 [0004] In the prior art, such as figure 1 As shown, the display panel 1 includes a plurality of signal lines 30 located in the display area 2 , and after the wiring of the above signal lines is completed, the above signal lines 30 need to be electrically tested. [0005] Currently, the electrical test method for the signal line 30 is as follows: one end of the lead wire 50 is connected to the signal line 30 , and the other end is connected to the contact terminal 40 . When an electrical signal is applied to the contact terminal 40 , the signal line 30 is electrically tested. [0006] During the electrical testing process, the number of contact terminals 40 is much smaller than the number of signal lines 30 due to the larger occupi...
