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 is, for The electrode area of ​​the display panel with a higher yield will also be equipped with a short circuit bar, so in order to avoid the occurrence of a short circuit caused by the exposure of the short circuit bar, it is also necessary to use a laser to cut off the electrode area on the display panel that does not need to be tested. Short-circuit bar, this redundant cutting process will not only reduce the production capacity of the display panel, but also reduce the utilization rate of the display panel

Embodiment 1

[0031] Such as figure 1 As shown, this embodiment provides an array substrate, which includes: a substrate, 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 substrate; 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 switching unit 1 is used to control whether the signal line 2 connected to it is electrically connected to the shorting bar 3 .

[0032] Since each signal line 2 in this embodiment is connected to a switch unit 1, 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 short-circuit 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 can display, and the display condition of...

Embodiment 2

[0034] Such as figure 1 As shown, this embodiment provides an array substrate, which includes: a base, a plurality of signal lines 2 , a shorting bar 3 , a switch unit 1 , and a control unit 4 . Wherein, 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 each signal line 2 is connected with a switch unit 1; the control unit 4 communicates with each switch through a control line 6 The unit 1 is connected to control the switching on and off of the switching unit 1 , so as to control whether the signal line 2 connected to the switching 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 short-circuit bar 3, so that the detection The signal is i...

Embodiment 3

[0049] This embodiment provides a display device, which includes the array substrate in Embodiment 1 or Embodiment 2. Wherein, the display device in this embodiment can be any product or component with a display function, such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a digital photo frame, and a navigator.

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...
