Embodiment 1

[0046] refer to Figure 2 to Figure 4 , an embodiment of the present invention provides an array substrate, including a plurality of connection areas 2 for connecting drive units, and a plurality of test areas 1 for connecting test heads 9; each connection area 2 is provided with a plurality of connection terminals 21. Each connection terminal 21 is connected to the lead wire 3; each test area 1 is provided with a plurality of test terminals 11, and the number and arrangement of the test terminals 11 in any two connection areas 2 are the same;

[0047] The test area 1 is divided into an independent test area 19 and a shared test area 18; each independent test area 19 corresponds to a connection area 2, wherein all test terminals 11 are electrically connected to the connection terminals 21 in the corresponding connection area 2; each shared The test area 18 corresponds to a plurality of connection areas 2 , wherein a plurality of test terminals 11 are respectively electrically ...

Embodiment 2

[0091] An embodiment of the present invention provides a display panel, which includes:

[0092] the above-mentioned display module;

[0093] Drive unit connected to the connection area.

[0094] Optionally, the driving unit includes a driving chip (IC) or a chip on film (COF).

[0095] That is to say, a driving unit such as a chip-on-chip film can be connected to the connection area of ​​the above display module, and the short-circuit ring can be cut off, so as to obtain a display panel with display capability.

[0096] Specifically, the display device can be a liquid crystal display (LCD) panel, an organic light-emitting diode (OLED) display panel, electronic paper, a mobile phone, a tablet computer, a TV set, a monitor, a notebook computer, a digital photo frame, a navigator, etc. products or components.

Abstract

The invention provides an array substrate, a display module and its testing method, and a display panel, which belong to the field of display technology and can at least partially solve the problem that it is difficult (especially when the PPI is high) to set a test area for the existing display module. The array substrate of the present invention includes a plurality of connection areas for connecting drive units, and a plurality of test areas for connecting test heads; each connection area is provided with a plurality of connection ends, and each connection end is connected to a lead; each There are multiple test terminals in the test area, and the number and arrangement of test terminals in any two connection areas are the same; the test areas are divided into independent test areas and shared test areas; each independent test area corresponds to a connection area, and all test terminals All of them are electrically connected to the connection terminals in the corresponding connection areas; each shared test area corresponds to a plurality of connection areas, and a plurality of test terminals are respectively electrically connected to the connection terminals in the corresponding connection areas.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a display module and a testing method thereof, and a display panel. Background technique [0002] refer to figure 1 After the array substrate and the box substrate (such as the color filter substrate) are combined to form a display module, the test can be performed first, and then the drive unit such as chip-on-film (COF) is connected to each connection area 2 of the array substrate to obtain a display panel. [0003] There are multiple connection ends in each connection area 2, and each connection end is connected to a lead wire 3 (such as a data line, a common electrode line), and some connection ends (such as a connection end connected to a data line) can also be connected to each other through a short-circuit ring. Connect to discharge static electricity during preparation (the short circuit ring will be cut later). Each connection area 2 i...
