ARRAY SUBSTRATE AND DISPLAY DEVICE

Abstract

The present invention discloses an array substrate and a display device. The present invention employs a flip pixel framework of a DD+G wiring method, and a design of disposing a GOA circuit on a source electrode driver side. Because two of the data lines adjacently and parallelly enter an AA region, the gate electrode fanout wire and the two data lines are not adjacent to each other but parallelly extend in AA region, which prevents coupling between the gate electrode fanout wire and the data lines signal. The method of using the width of two pixel units to perform a layout of a GOA circuit of one level further facilitates achievement of the narrow border.

Description

FIELD OF INVENTION

The present invention relates to a field of display technologies, especially relates to an array substrate and a display device.

BACKGROUND OF INVENTION

Liquid crystal display (LCD) devices have advantages of light weight, low consumption, low working voltage without radiation, and are used extensively in fields of computer displays, television displays, mobile phones.

With constant development of liquid crystal display technologies, people has increasing demands to display devices. In response the market demands, large size, high resolution, ultra-narrow border (UNB) have become market trends. The ultra-narrow border means further compression a width of a border region to achieve further expansion of an area of an effective display region (active area, AA). The demands for the ultra-narrow border poses a higher challenge to LCD design and manufacturing.

In recent years, the spliced display, which has received widespread market attention, has put forward a demand for the extremely narrow border technology. Spliced gaps have been reduced extremely, a requirement of a gap from AA to AA to be less than 1 mm has become a future trend.

TECHNICAL ISSUE

With reference to FIGS. 1 and 2, wherein FIG. 1 is a schematic view of a wire layout of an embodiment of a conventional array substrate, and FIG. 2 is a schematic view of a wire layout of another embodiment of a conventional array substrate.

With reference to FIG. 1, a gate driver on array (GOA) circuits 11 and a source electrode driver circuit (not shown in the figures) are disposed on the same side, in other words, both are disposed on a source electrode driver side (Source Border) 101. Furthermore, a width of one sub-pixel (Sub_Pixel) 12 is used for layout of the GOA circuit 11 of one level. Between adjacent two of the GOA circuits 11, one gate electrode fanout wire (Gate Fanout) 13 and one data lines (Data Line) 14 are arranged parallelly and adjacently and extend in an AA region 100 of the display panel, which a G(Gate Fanout)D(Data Line) wiring method is employed. Specifically, one gate electrode fanout wire 13 and one data lines 14 extend adjacently and parallelly in a region between adjacent two of the sub-pixels 12. Such method of employing a width of one sub-pixel to implement layout of a GOA circuit of one level makes the width of the Source Border wider. Furthermore, the wiring method of the GD has an intermutually coupling (Couple) existing between the gate electrode fanout wire and the data lines, which causes the risk of display mura.

With reference to FIG. 2, a GOA circuit 21 and a source electrode driver circuit (not shown in the figures) are disposed on the same side, in other words, both are disposed on a source electrode driver side 201. Furthermore, a width of two horizontally adjacent sub-pixels 22 are used for layout of the GOA circuit 21 of one level. Two parallel data lines 241, 242 exist between adjacent two GOA circuits 21. One data line 241 and one gate electrode fanout wire 23 are arranged adjacently and parallelly and extend in the AA region 200 of the display panel. Another data line 242, after extending out a layout region of the GOA circuit 21, is folded toward a side away from the data line 241, and then extends in the AA region 200 of the display panel, namely, a normal circularly arranged pixel (Cyclic pixel) framework wiring method of G(Gate Fanout)D(Data Line)+D(Data Line) I used. Specifically, one gate electrode fanout wire 23 and one data lines 241 adjacently and parallelly extend a region between a first column and a second column of the sub-pixels 22 in adjacent three columns of the sub-pixels 22 (first two columns of a broken frame shown in the figure), another data line 242 extend between a region of the second column and a third column of the sub-pixels 22 in adjacent three columns of the sub-pixels 22 (later two columns of the broken frame shown in the figure). Such method using a width of two sub-pixels to implement layout of a GOA circuit of one level reduces a width of the Source Border. However the wiring method of the GD+D still has an intermutually coupling) existing between the gate electrode fanout wire and the data lines, which causes the risk of display mura.

The data lines 34 is configured to provide a drain electrode of the TFT of the pixel unit 32 with Data signals. Specifically, data lines entering the the display region 300 correspond to output channels of the source electrode driver unit (Source Driver) disposed in the source electrode driver region 301. Also the source electrode driver unit provides Data signals.

Specifically, the GOA circuit 31 and the source electrode driver unit are configured for a source electrode driver (Source Driver) and a gate electrode driver (Gate Driver) in the display panel respectively to output corresponding signals to the display panel to drive the display panel to display.
