[0002] At present, the wearable display module industry is pursuing a narrower frame to achieve a higher screen-to-body ratio and a better visual experience. In the traditional COF binding structure, Figure 4 As shown, the chip S1 and the binding belt S2 are combined together. Although the frame can be made smaller, the material cost is high and an additional FOF binding is required.

[0003] Chinese utility model patent document CN206388704U discloses an array substrate, comprising: a substrate; and a welding wire arranged on one side of the substrate, the welding wire forming an identification mark. The identification mark is a barcode or a two-dimensional code. The barcode includes a plurality of welding wires, and there is a gap between adjacent welding wires. The distance between any two adjacent welding wires is not exactly the same. The width of the welding wire in a first direction is greater than or equal to 0.012 mm, and the first direction is a horizontal direction. The distance between two adjacent welding wires is greater than or equal to 0.012 mm. The colors of any two welding wires are different. At least two welding wires have different widths in the horizontal direction.

[0004] Obviously, this patent sets the welding wire on one side of the substrate into a preset shape to form an identification mark, so that when tracing the information of the display panel, the welding wire can be directly identified by a conventional barcode reader. The process is simple, there is no need to increase the equipment cost, and there is no need to occupy the border area of ​​the display panel, thus realizing a narrow border design of the display panel. This structure cannot solve the problem of excessive size in the existing COF binding structure.

[0005] Chinese invention patent document CN109244083B discloses a display backplane, characterized in that it comprises: a base substrate, the base substrate having a circular display area and a ring-shaped non-display area surrounding the display area; a thin film transistor TFT structure layer located on the base substrate, the TFT structure layer comprising a gate pattern, a source-drain pattern and a semiconductor active layer pattern insulated from each other; a first electrode layer located on the TFT structure layer, the first electrode layer comprising n data lines arranged in the same layer and a plurality of first electrodes, the first electrode being one of a cathode and an anode, n being an integer greater than 1, the n data lines comprising k data line groups, each of the data line groups comprising m The data line, m is an integer greater than 1, k=n / m, and k is a positive integer; k data terminals located on the bonding area of ​​the non-display area of ​​the base substrate, each of which is connected to one of the data line groups; n switch units located on the base substrate, the n switch units are connected in series with the n data lines in a one-to-one correspondence, the n switch units include m groups of switch units, each group of switch units includes k switch units, and the k switch units are respectively connected to one of the data lines in the k data line groups; m control terminals located on the bonding area, each of which is connected to a group of switch units through a control line, for controlling the opening and closing of the group of switch units. A buffer layer is provided on the base substrate; the TFT structure layer includes the semiconductor active layer pattern, the first insulating layer, the gate pattern, the second insulating layer, the interlayer insulating layer, the source and drain pattern and the flat layer, which are sequentially stacked in a direction away from the base substrate. The semiconductor active layer pattern also includes a plurality of conductive lines, which are connected to the k data terminals, and the source-drain pattern also includes: n conductive blocks, which are connected to the n conductive lines through second vias; the n data lines are connected to the plurality of conductive blocks through third vias, so as to be connected to the k data terminals through the plurality of conductive blocks and the plurality of conductive lines. The display backplane also includes: a pixel definition layer located on the first electrode layer; a light emitting layer located on the pixel definition layer; and a second electrode layer located on the light emitting layer, wherein the second electrode layer includes a plurality of second electrodes, and the second electrodes have different polarities from the first electrodes.The light-emitting layer includes a plurality of light-emitting units arranged in a matrix, each light-emitting unit includes: a red light-emitting block, a green light-emitting block and a blue light-emitting block, the red light-emitting block and the green light-emitting block are arranged in a column direction, the blue light-emitting block is located on one side of the column where the red light-emitting block and the green light-emitting block are located, the n data lines include a first data line for driving the red light-emitting block to emit light, a second data line for driving the green light-emitting block to emit light, and a third data line for driving the blue light-emitting block to emit light, and every two adjacent first data lines and second data lines are located at a first gap in a column of light-emitting units, the first gap is a gap between the column where the red light-emitting block and the green light-emitting block are located and the blue light-emitting block, and each third data line is located at a gap between two columns of light-emitting units. The first electrode is an anode, the second electrode is a cathode, and the switch unit is a TFT.

[0006] Obviously, the patent arranges multiple data lines in the same layer as the first electrode, and reduces the load on each data line while managing multiple data lines at each data terminal. Therefore, under the premise of ensuring effective charging of each sub-pixel, the length of the bonding area is shortened, thereby achieving a narrow frame of the circular display panel. This method of achieving a narrow frame is too complicated and costly. Utility Model Content
