[0002] Nowadays, in the display field, especially in the high-end display field, OLED is gradually replacing LCD to become the mainstream. The smaller the borders of display modules are, the more the end customers are pursuing. The smaller the borders are, the smaller the black borders of the whole machine are, and the larger the screen-to-body ratio is. Whether the borders can be made smaller has become an important indicator to measure the technical capabilities of a display manufacturer.

[0003] OLED has now entered the FMLOC (Flexible MultiLayer On Cell, flexible multi-layer structure, the FMLOC process refers to the production of a metal grid electrode layer on the packaging substrate of the display panel for touch control, without the need for an external TSP) era. The touch layer has changed from the traditional add-on structure to the FMLOC structure. The touch layer is integrated into the display layer, which greatly reduces the thickness of the module. However, this brings a new problem. The display layer circuit of the original add-on structure only needs to arrange the display signal lines on the substrate (PI), while the FMLOC structure integrates the touch layer and the display layer and shares the substrate.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] like Figure 1 As shown, in a traditional solution, an OLED display typically consists of a display body, a D-IC, a flexible circuit board (FPC), and a rigid circuit board. The width of the bottom bezel is determined by the display signal lines 1 and the touch signal lines 2. Both the display signal lines and the touch signal lines are routed from the bottom bezel to the same flexible circuit board, resulting in a relatively large bottom bezel. Currently, mobile phones all use this solution. Because mobile phones are small, fewer signal lines are required compared to larger sizes at the same resolution. Therefore, even if the touch signal lines and the display signal lines are routed from the same side, the bezel will not widen significantly. However, as the size increases to 13, 14, or even 17 or 18 inches, the required routing space increases significantly. If the same-side routing method is still used, the bezel will become relatively large. Therefore, a new solution is urgently needed to address the problem of excessively wide bottom bezels in medium and large-sized OLED FMLOC structures. This embodiment addresses this issue by providing a display panel that separates the touch signal lines 2 and a portion of the display signal lines 1, allowing them to be routed from opposite sides, thereby narrowing the bezel.

[0032] refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 7Specifically, this embodiment provides a display panel having an FMLOC structure, comprising a substrate 100, and a display wiring layer 200, a light-emitting layer 300, an encapsulation layer 400, a touch wiring layer 500, and a touch protection layer 600 sequentially stacked on the substrate 100;

[0033] The display panel further includes a display area and a non-display area located outside the display area. The non-display area is distributed with touch signal lines 2 and display signal lines 1 led from the display area. The display signal lines 1 are located in the display wiring layer 200, and the touch signal lines 2 are located in the touch wiring layer 500. The non-display area includes a first frame area and a second frame area. The first frame area and the second frame area are respectively located on two adjacent or opposite sides of the display area.

[0034] The first border area is provided with a first binding area, the second border area is provided with a second binding area, the output ends of some of the display signal lines 1 and the touch signal lines 2 are provided in the first binding area, and the output ends of some of the signal lines are provided in the second binding area.

[0035] In the traditional solution, only a binding area is set in the lower frame, and the display signal line 1 and the touch signal line 2 are all connected to the binding area of ​​the lower frame, which makes the width of the lower frame relatively large. In this embodiment, a first binding area and a second binding area are respectively set in the adjacent or opposite first frame area and the output ends of a part of the display signal line 1 and the touch signal line 2 are set in the first binding area, and the output ends of a part of the display signal line 1 and the touch signal line 2 are set in the second binding area, that is, the output ends of the display signal line 1 and the touch signal line 2 are divided into pieces and dispersedly led out from different sides, thereby narrowing the width of the frame. Figure 1 and Figure 2 For comparison, Figure 1 The output end of the touch signal line 2 is no longer set at the lower frame, but is set at the upper frame, which will leave extra space at the lower frame, and this extra space can be omitted, thereby shortening the distance from the lower edge to the display area and achieving a narrow frame. Figure 3 for Figure 1 An enlarged schematic diagram of the area marked by the dotted circle in ( Figure 3 The touch signal line 2 is not shown. Figure 4 for Figure 2 The enlarged schematic diagram of the area marked by the dotted circle, Figure 3 and Figure 4 By comparison, it is obvious that Figure 3 The width of the lower border is determined by the display signal line 1 and the touch signal line 2. The edge of the lower border is still a certain distance away from the edge of the display signal line 1. Figure 4Due to the transfer of the output end of the touch signal line 2, the area occupied by the touch signal line 2 can be omitted, so that the distance between the edge of the lower frame and the edge of the display signal line 1 is significantly reduced, L>L′, achieving a narrow frame.

[0036] It should be noted that, in this embodiment, the display signal line 1 and the touch signal line 2 are divided into two parts, that is, the display signal line 1 and the touch signal line 2 are led out from different two sides, but this is not limited to the above. The display signal line 1 and the touch signal line 2 can also be divided into three parts, and the non-display area includes a first frame area, a second frame area and a third frame area, and the first frame area, the second frame area and the third frame area are respectively provided with a corresponding binding area. The display signal line 1 and the touch signal line 2 can also be divided into four parts, and the non-display area includes a first frame area, a second frame area, a third frame area and a fourth frame area, and the first frame area, the second frame area, the third frame area and the fourth frame area are respectively provided with a corresponding binding area. When the display panel is irregular, the display signal line 1 and the touch signal line 2 can also be divided into more components, and the non-display area is correspondingly divided into more frame areas, and corresponding binding areas are provided on the corresponding frame areas. The specific setting can be based on actual needs.

[0037] In an embodiment where the non-display area includes a first border area and a second border area, the first border area and the second border area can be adjacent to each other or opposite to each other. In a specific embodiment, for the aesthetics of the display panel, the first border and the second border are opposite to each other, but the present invention is not limited to this.

[0038] It should be noted that the drawings only schematically illustrate the area where the touch signal lines 2 and the area where the display signal lines 1 are located, and do not specifically depict each line.

[0039] The following takes the non-display area including the first frame area and the second frame area that are oppositely arranged as an example to specifically describe the distribution of the display signal lines 1 and the touch signal lines 2 .

[0040] In an exemplary embodiment, the output end of the display signal line 1 is set at the first binding area, and the output end of the touch signal line 2 is set at the second binding area. Figure 2 .

[0041] In an exemplary embodiment, the output end of the display signal line 1 is set in the first binding area, the output end of part of the touch signal line 2 is set in the first binding area, and the output end of part of the touch signal line 2 is set in the second binding area. Figure 5 .

[0042] In an exemplary embodiment, some output ends of the display signal lines 1 are set in the first binding area, some output ends of the display signal lines 1 are set in the second binding area, and the output ends of the touch signal lines 2 are set in the first binding area.

[0043] In an exemplary embodiment, the output ends of some of the touch signal lines 2 are set in the first binding area, the output ends of some of the touch signal lines 2 are set in the second binding area, and the output ends of some of the display signal lines 1 are set in the first binding area, and the output ends of some of the display signal lines 1 are set in the second binding area.

[0044] It should be noted that the ratio of the number of signal lines with output ends arranged in the first binding area to the number of signal lines with output ends arranged in the second binding area can be set according to actual needs, for example, it can be 1:1, 1:2, 1:3, etc.

[0045] If the display signal line 1 and the touch signal line 2 are set separately, it is necessary to set an IC for processing the display signal and an IC for processing the touch signal in different binding areas respectively, and the display signal also needs to be connected to the display driver IC 10 (D-IC) for controlling the display driver. This increases the complexity of the line distribution and also increases the number of IC settings. In order to simplify the line distribution, in some preferred embodiments, the output end of the display signal line 1 is set in the first binding area, the output end of the touch signal line 2 is set in the second binding area, or all the output ends of the display signal line 1 are set in the first binding area. By setting at least part of the output ends of the touch signal line 2 in the second binding area, the border corresponding to the output end of the display signal line 1 is narrowed. Based on this, the distribution method of the touch signal line 2 is specifically introduced below.

[0046] In an exemplary embodiment, the touch signal line 2 includes a driving electrode signal line 21 and a sensing electrode signal line 22, the output end of the driving electrode signal line 21 is set in the first binding area, and the output end of the sensing electrode signal line 22 is set in the second binding area, or the output end of the sensing electrode signal line 22 is set in the first binding area, and the output end of the driving electrode signal line 21 is set in the second binding area.

[0047] In an exemplary embodiment, the touch signal line 2 includes a driving electrode signal line 21 and a sensing electrode signal line 22, and the output ends of some of the driving electrode signal lines 21 and some of the sensing electrode signal lines 22 are located in the first binding area, and the output ends of some of the driving electrode signal lines 21 and some of the sensing electrode signal lines 22 are located in the second binding area.

When the output ends of the touch signal lines 2 are all set in the first binding area, the touch signal lines 2 will increase the corresponding frame. In this embodiment, the output ends of 1 / 3 of the driving electrode signal lines 21 are set in the first binding area, and the width of 1 / 3 of the driving electrode signal lines 21 (from the display area to the first frame, refer to Figure 5 In the X direction, the width of the display signal line 1 will not exceed that of the display signal line 1, and the output ends of 2 / 3 of the driving electrode signal lines 21 are set in the second binding area. Compared with setting the output ends of all the driving electrode signal lines 21 in the second binding area, the width of the first border area is reduced while the width of the second border area is also reduced.

[0050] In an exemplary embodiment, the touch signal line 2 includes a driving electrode signal line 21 and a sensing electrode signal line 22, the output ends of some of the sensing electrode signal lines 22 are located in the first binding area, and the output ends of some of the sensing electrode signal lines 22 and the output ends of the driving electrode signal lines 21 are located in the second binding area.

[0051] refer to Figure 8 In an exemplary embodiment, the display panel includes a substrate 100, and a display wiring layer 200, a light-emitting layer 300, an encapsulation layer 400, a touch wiring layer 500 and a touch protection layer 600 sequentially stacked on the substrate 100, the display wiring layer 200 is distributed with the display signal line 1, and the touch wiring layer 500 is distributed with the touch signal line 2.

[0060] refer to Figure 1 and Figure 6 In the conventional solution, the non-display area is provided with only one binding area, and correspondingly only one flexible circuit board is provided for signal connection between the display panel and the main circuit board 5. Since the touch signal line 2 needs to pass through the flexible circuit board together with the display signal line 1 (reference Figure 6 The first flexible circuit board 3) is then connected to the main circuit board 5PCB. The touch integrated chip (TP-IC) that processes the touch signal and the control integrated chip (T-con IC) that processes the display signal need to be integrated into the main circuit board 5. When the main circuit board 5 is folded back to the backlight side of the display panel ( Figure 6The main circuit board 5 is folded back to the backlight side of the display panel), and the multiple touch signal lines 2 and the multiple display signal lines 1 need to pass through the corresponding ICs (the touch integrated chip 7 for processing the touch signal and the control integrated chip 6 for processing the display signal) first, and then be led out from the corresponding ICs after signal processing and gathered together through a flexible circuit board (refer to Figure 6 The second flexible circuit board 8) is connected to the terminal, and the circuit design is relatively complicated.

The touch signal line 2 is connected to the touch integrated chip 7 for processing the touch signal located on the second sub-flexible circuit board 4. After signal processing, it is connected to the main circuit board 5. Since it is a processed signal, no extra wiring is required. It is directly led out to the second flexible circuit board 8 through a wiring, and merged with the wiring led out of the touch integrated chip 6 for processing the display signal, and connected to the terminal through the second flexible circuit board 8.
