Fig. 1 shows a schematic structural diagram of a display device according to an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present disclosure provides an array substrate, including:
a first substrate 1 having an open area 11;
the second substrate 2 is arranged opposite to the first substrate 1 in a superposed manner, at least one side edge of the second substrate 2 is provided with an opening area 21, the opening area 21 surrounds the opening area 11, and at least part of the edge of the opening area 11 is tangent to at least part of the edge of the opening area 21.
Specifically, the opening region 11 is formed by digging a hole at a position of the first substrate 1 near the upper edge; the opening region 21 is formed by grooving from the upper edge of the second substrate 2.
The hole digging requirement of a user can be directly met by arranging the hole opening region 11 on the first substrate 1, and the special-shaped cutting requirement of the user can be met by arranging the opening region 21 on the second substrate 2, so that different special-shaped panel products such as V-Notch, water drop screen and Liu Haibing are obtained. In particular, the opening area 21 surrounds the opening area 11, so that the second substrate 2 is not affected when the first substrate 1 is subjected to special-shaped cutting, at least part of the edge of the opening area 11 is tangent to at least part of the edge of the opening area 21, and the edge tangent to the opening area 21 of the opening area 11 can be utilized to align when the second substrate 2 is subjected to special-shaped cutting, so that the accuracy of special-shaped cutting is ensured, and the processing quality of a product is improved.
According to the array substrate provided by the embodiment of the disclosure, by arranging the first substrate 1 and the second substrate 2 which are overlapped up and down, and arranging the open area 11 on the first substrate 1 respectively, and arranging the open area 21 which can surround the open area 11 and is tangential to at least part of the edge of the open area 11 on the second substrate 2, different product structure requirements of users can be met by adopting a set of MASK (MASK) exposure and etching process design, the diversification of products is realized, regular products such as a hole digging screen can be processed and obtained, and different special-shaped products such as V-Notch, a water drop screen and Liu Haibing can be processed and obtained; meanwhile, the alignment problem during cutting of different special shapes can be solved, the product processing precision is improved, the design pressure and the material pressure during product design and processing are greatly relieved, and the processing cost is effectively reduced.
In some embodiments, as shown in fig. 1, the open area 11 and the open area 21 are symmetrically disposed along the Y-axis direction of the array substrate, and the symmetry axis of the open area 11 coincides with the symmetry axis of the open area 21. Namely, the open hole area 11 and the open hole area 21 are of bilateral symmetry structures so as to process regular blind holes or special-shaped structures, thereby being beneficial to attractive appearance of products; and the symmetry axis of the open area 11 coincides with the symmetry axis of the open area 21, so that the lower edge of the open area 11 is tangent to the lower edge of the open area 21 (the tangent point is A), and the open area 11 is utilized for alignment when the special-shaped structure product is processed later, thereby ensuring the product precision.
In this embodiment, the open area 11 and the open area 21 that are matched with each other are disposed in the middle of the array substrate, and in a specific implementation, the open area 11 and the open area 21 may also be disposed on the left side or the right side of the array substrate.
In other embodiments, the symmetry axis of the open area 11 and the symmetry axis of the open area 21 may not coincide, for example, when the open area 21 is larger, one open area 11 may be disposed on the left side and the right side of the symmetry axis of the open area 21, i.e. two open areas 11 may be disposed to meet the diversified demands of users.
It will be understood that the X-axis direction of the array substrate refers to the width direction of the array substrate, the Y-axis direction refers to the length direction of the array substrate, and the Z-axis direction of the array substrate refers to the thickness direction of the array substrate.
The shape of the openings of the open area 11 may be specifically any geometric shape such as a circle, an ellipse, a rectangle, a square, a triangle, a diamond, or other irregular shape. In this embodiment, the shape of the open area 11 is circular to meet the blind hole requirement of the user. The open hole region 11 is set as a blind hole region, so that components such as a camera in the blind hole region can be protected, and an optical element (e.g., a polarizing film or the like) can be arranged at a closed end of the blind hole region, so that imaging effects and the like of a product can be adjusted in cooperation with the camera.
As shown in fig. 1, the shape of the opening area 21 is an arc-shaped groove, and two side edges of the arc-shaped groove smoothly transition with the edge of the second substrate 2.
Further, the width of the arc-shaped groove gradually decreases from the outside to the inside from the edge of the second substrate 2. That is, the opening of the opening area 21 gradually increases from inside to outside, so that processing of different shaped structures can be facilitated, and different shaped structures (Notch shaped structures) such as V-Notch, drip screen, liu Haibing and the like can be formed only by cutting. The smooth transition between the two side edges of the arc-shaped groove and the edge of the second substrate 2 is also convenient for processing.
In a specific implementation, the shape of the opening area 21 may be a regular groove such as a "U-shape" or a "concave shape", for example, when the opening area is a "concave shape", processing of the Ji Liuhai Notch structure may be facilitated, but processing of the V-Notch is inconvenient, and more material may need to be cut during processing of the V-Notch, which is not beneficial to implementation of the narrow frame. When the shape of the opening area 21 is "U-shaped" or "concave", the edges of the two sides of the arc-shaped groove and the edge of the second substrate 2 can directly pass through right angle transition, and also can be chamfered at the right angle to realize smooth transition, so as to facilitate the processing of the special-shaped structure or other structures.
In some embodiments, as shown in fig. 1 and 2, at least two first alignment marks 31 are disposed on the first substrate 1 to align with two side edges of the opening area 21.
During specific processing, the special-shaped cutting equipment performs counterpoint through grabbing the at least two first counterpoint marks 31, determines the cutter wheel cutting position of the special-shaped cutting equipment, and finally realizes the Notch shape structure.
In this embodiment, as shown in fig. 1, a first alignment mark 31 is etched on the left and right sides above the opening area 11 to align with the left and right edges of the opening area 21, respectively, i.e. the line between the first alignment mark 31 and the edge points of the two side edges of the opening area 21 is parallel to the Y axis of the array substrate.
The array substrate includes a display Area (AA) and a non-display Area located inside and around the display Area, the open Area 11 and the open Area 21 are both located in the non-display Area, and the first alignment mark 31 is located above the open Area 11 and located in the non-display Area.
Further, the distance L between the first alignment mark 31 and the top edge of the display area of the array substrate is 200-400um (e.g. 300 um), so that the alignment is ensured, and meanwhile, the non-display area is prevented from being excessively large, so as to realize a narrow frame or full screen design.
In this embodiment, the first alignment mark 31 is formed on the SD layer (source/drain metal layer) of the first substrate 1, and the SD layer has a structure of Ti/Al/Ti (titanium/aluminum/titanium). The Ti/Al/Ti three-layer structure can improve the product quality of the array substrate.
In some embodiments, the first alignment mark 31 is a cross-shaped mark or a zig-zag mark as shown in fig. 3. Preferably, the cross-shaped mark has a length a of 100um and a width b of 20 um. In particular embodiments, the first alignment mark 31 may have other shapes as long as it has a crossing point to facilitate positioning.
In some embodiments, the edge of the opening area 21 is further provided with a plurality of second alignment marks 32, and the wires of the second alignment marks 32 form a dicing line 4, and the dicing line 4 is cut to form the Notch structure.
As shown in fig. 1 and 2, a plurality of third alignment marks 33 are provided at the connection of the edges of the first substrate 1 and/or the second substrate 2 so as to form corresponding cutting lines, thereby cutting the edges of the array substrate to form rounded edges, etc.

The gate signal lines 5 are located in the display area, the gate driving circuits are located in the non-display area, and each row of gate signal lines 5 located in the display area is connected to each row of gate driving circuits located in the non-display area.
The array substrate further includes an array of M rows and N columns of pixels disposed in the display area, where the array of pixels is disposed corresponding to the gate signal lines 5, and the display area of the array substrate is provided with the M gate signal lines 5, for example, 2402 gate signal lines 5 are provided in this embodiment, and pixels (pixels) in the same row in the array of pixels are all connected to the same gate signal line 5.
The grid driving circuit outputs a grid scanning driving signal to drive a grid signal line 5 in the panel, so that a thin film transistor in the display area is conducted to charge the pixel; meanwhile, the gate driving circuits sequentially transmit signals in a progressive scanning mode, and after the scanning of the gate scanning driving signals input through one row of gate signal lines 5 is completed, the next row of gate driving circuits are controlled to input signals to the gate signal lines 5 positioned in the row, and the signals are sequentially transmitted until the scanning of the gate scanning driving signals input to the last row of gate signal lines 5 is completed.
The array substrate further comprises Data lines (Data) which are mutually perpendicular to the gate signal lines 5 and are arranged in a crossing and insulating mode, and a Data driving circuit used for driving the Data lines, namely the array substrate is provided with N Data lines, and pixels in the same column in the pixel array are all connected to the same Data line. When a scanning signal is input through the grid signal line 5, the thin film transistor is turned on, and at the moment, a gray-scale signal is input through the data line, so that the pixel unit can be driven, and a display function is realized.
As shown in fig. 5, each pixel unit in the pixel array may include at least three sub-pixels to respectively correspond to the red filter unit, the green filter unit and the blue filter unit on the color film substrate.
In this embodiment, the first gate driving unit 61 and the second gate driving unit 62 are respectively connected to the left and right sides of each row of gate signal lines 5, so that when the opening area 21 is cut, even if the gate signal lines 5 are cut off, the cut-off gate signal lines 5 can be respectively scanned and driven normally by the first gate driving unit 61 and the second gate driving unit 62, so that the pixel units are driven normally to display, and no other abnormal or bad phenomenon occurs; or may display with another normally driven pixel cell when an abnormality occurs in one of the two GOA cells located in the same row.

By reducing the width-to-length ratio and the pipe section number of the thin film transistor, the ESD protection capability is ensured, and meanwhile, the space occupation ratio of the ESD unit is reduced, so that the ESD unit is ensured not to be damaged. For example, in this embodiment, the size of the thin film transistor may be 34 (Poly) by 3 (node number)/6 (Gate), where 34 (Poly)/6 (Gate) represents the width-to-length ratio.
