Problems solved by technology

[0003] However, for the above-mentioned detection method, the inventor found that after the detection of the display panel is completed, adding a laser for cutting short-circuit bars will greatly increase the production cost of manufacturing the display panel; For the display panel with high yield rate, it is not necessary to perform detection. If the above-mentioned detection method is used to detect the display panel, all the electrode areas of the display panel will be equipped with short-circuit bars, that

Example Embodiment

[0030] Example 1:

[0031] like figure 1 As shown, this embodiment provides an array substrate, which includes: a base, a plurality of signal lines 2, a shorting bar 3, and a switch unit 1; specifically, a plurality of signal lines 2 are arranged on the base; each signal line 2 is connected to The corresponding shorting bar 3 is connected to each signal line 2 with a switch unit 1 ; wherein the switch unit 1 is used to control whether the signal line 2 connected thereto is electrically connected to the shorting bar 3 .

[0032] Since a switch unit 1 is connected to each signal line 2 in this embodiment, and when the switch unit 1 is in a closed state, the signal line 2 connected to the switch unit 1 will be electrically connected to the shorting bar 3, so that the detection The signal is input to the signal line 2 connected to the short-circuit bar 3 through the short-circuit bar 3, so that the pixel unit connected to the signal line 2 is displayed, and the display panel is j...

Example Embodiment

[0033] Example 2:

[0034] like figure 1 As shown, this embodiment provides an array substrate, which includes: a substrate, a plurality of signal lines 2 , a shorting bar 3 , a switch unit 1 , and a control unit 4 . Among them, a plurality of signal lines 2 are arranged on the substrate; each signal line 2 is connected to its corresponding short-circuit bar 3, and a switch unit 1 is connected to each signal line 2; the control unit 4 communicates with each switch through the control line 6 The unit 1 is connected to control the switch unit 1 to be turned on and off, so as to control whether the signal line 2 connected to the switch unit 1 is electrically connected to the shorting bar 3 .

[0035] Specifically, the control unit 4 applies a turn-on voltage to each switch unit 1 on the same control line 6 to turn on the switch unit 1. At this time, the signal line 2 connected to the switch unit 1 will be electrically connected to the shorting bar 3, so that the detection The s...

Example Embodiment

[0048] Example 3:

[0049] This embodiment provides a display device including the array substrate in Embodiment 1 or Embodiment 2. The display device in this embodiment may be any product or component with display function, such as liquid crystal panel, electronic paper, OLED panel, mobile phone, tablet computer, TV, monitor, notebook computer, digital photo frame, navigator, etc.

Abstract

The invention provides an array substrate, a drive method thereof and a display device, and belongs to the technical field. The array substrate comprises a substrate body and multiple signal wires arranged on the substrate body; each signal wire is connected to a corresponding short-circuited bar and a switch unit; the switch units are used for controlling the signal wires connected to them whether or not in electrical connection with the short-circuited bars.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a driving method thereof, and a display device. Background technique [0002] In the existing CT detection (Cell Test; liquid crystal cell detection), the display panel is often tested with a shorting bar structure, which is mainly to install the shorting bar on the electrode area of ​​the display panel, so that the shorting bar Short-circuit the circuit in the electrode area; then, insert a plurality of probes into the detection area to be detected, so that each probe is correspondingly inserted on a circuit, so as to load an electrical signal to the circuit in the electrode area , so that the display panel that receives the electrical signal emits light, and checks whether the display panel is qualified through the luminescence of the display panel; finally, after the display panel is inspected, in order to avoid the circuit in the electrode are...
