[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] The terms used in the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The words "first", "second" and similar words used in the present disclosure specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one" or "one" do not indicate a quantitative limit, but indicate that there is at least one. Unless otherwise specified, similar words such as "include" or "comprise" mean that the elements or objects appearing in front of "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, and do not exclude other elements or objects. Similar words such as "connect" or "connected" are not limited to physical or mechanical connections, and can include electrical connections, whether direct or indirect.

[0040] As used in this disclosure and the appended claims, the singular forms "a", "said", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

[0041] In some embodiments, the display panel includes a display area and a frame surrounding the edge of the display area. The display area is provided with a display screen, a touch sensing layer, and a fingerprint sensing layer. Among them, the touch sensing layer and the fingerprint sensing layer are arranged on the same layer and are arranged on one side of the display surface of the display screen. The touch sensing layer includes a plurality of first wirings extending outwardly into the frame, and the fingerprint sensing layer includes a plurality of second wirings extending outwardly into the frame. The plurality of first wirings and the plurality of second wirings are all connected to the control unit on the flexible circuit board, and the plurality of first wirings and the plurality of second wirings are arranged on the same layer in the frame. Since the plurality of first wirings and the plurality of second wirings are arranged at intervals on the same layer, this requires the frame to have a larger width to reserve space for the plurality of first wirings and the plurality of second wirings. A wider frame affects the screen-to-body ratio. Among them, the width of the frame is the distance between the edge of the display area and the side wall of the frame. Based on the above, an embodiment of the present disclosure provides a display panel and a terminal device.

[0042] Figure 1 FIG. 1 is a front view of a display panel according to an exemplary embodiment of the present disclosure. Figure 2 FIG. 1 is a cross-sectional view of a display panel according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the display panel includes: a display area 1 and a frame 2 surrounding the edge of the display area 1. Figure 2 As shown, the display area 1 is provided with a touch sensing layer 11, and the touch sensing layer 11 includes a plurality of first wirings 111 extending outwardly into the frame 2. The display area 1 is also provided with a fingerprint sensing layer 12, and the fingerprint sensing layer 12 includes a plurality of second wirings 121 extending outwardly into the frame 2. At least part of the plurality of first wirings 111 located in the frame 2 and at least part of the plurality of second wirings 121 located in the frame 2 are arranged in different layers.

[0043] It should be noted that the display area 1 is provided with a plurality of stacked film layers, including but not limited to a touch sensing layer 11, a fingerprint sensing layer 12, and an insulating layer. When manufacturing each film layer, at least one corresponding layer of routing (including a first routing 111 and a second routing 121) can be manufactured, and each layer of routing is manufactured and formed at the same time. The routing led out from a certain film layer may be opposite to the film layer, or may be located above or below the film layer. For example, when the routing is located above the film layer, it is necessary to lead the routing through the insulating layer above the film layer to the top and form it into an upper layer routing. Based on this, a layer of routing refers to routing that is manufactured and formed at the same time and is located in the same plane. Routing arranged in different layers means that they are not manufactured and formed at the same time and are located in different planes.

[0044] It is understandable that, in the frame 2, any or all of the plurality of first routing lines 111 and any or all of the plurality of second routing lines 121 are arranged in different layers, so as to avoid the plurality of first routing lines 111 and the plurality of second routing lines 121 being arranged in the same layer from occupying a large area in the width direction of the frame 2, so as to make full use of the space in the frame 2, achieve the effect of reducing the area occupied in the width direction of the frame 2, and thus reduce the width of the frame 2. Figure 1 As shown, X1 and X2 are the widths corresponding to different parts of the border 2.

[0045] Taking the touch sensing layer 11 as an example, the plurality of first wirings 111 include: a receiving signal wiring and a transmitting signal wiring, and the receiving signal wiring and the transmitting signal wiring can be arranged in different layers, that is, some of the plurality of first wirings 111 can be arranged in different layers with other first wirings 111, or they can be arranged in the same layer. Similarly, some of the plurality of second wirings 121 can be arranged in different layers with other second wirings 121, or the plurality of second wirings 121 can be arranged in the same layer. By laying out insulating materials or insulating layers, any number of the plurality of first wirings 111 can be arranged in the same layer with any number of the plurality of second wirings 121, or they can be arranged in different layers, so as to reduce the width of the frame 2.

[0046] In the display panel provided by the embodiment of the present disclosure, the touch sensing layer 11 includes a plurality of first wirings 111 extending outwardly into the frame 2, and the fingerprint sensing layer 12 includes a plurality of second wirings 121 extending outwardly into the frame 2. By making at least a portion of the plurality of first wirings 111 and at least a portion of the plurality of second wirings 121 be arranged in different layers, the space in the frame 2 can be fully utilized, and it is avoided that the plurality of first wirings 111 and the plurality of second wirings 121 are arranged in the same layer and occupy a large area in the width direction of the frame, which is beneficial to reducing the width of the frame 2, and further beneficial to increasing the screen-to-body ratio.

[0047] Figure 3 FIG. 1 is a schematic diagram of a plurality of first routing lines and a plurality of second routing lines arranged on different layers according to an exemplary embodiment of the present disclosure. Figure 2 and Figure 3 As shown, the plurality of first wirings 111 located in the frame 2 are all arranged in the same layer, the plurality of second wirings 121 located in the frame 2 are all arranged in the same layer, and the plurality of first wirings 111 and the plurality of second wirings 121 are arranged in different layers. Such an arrangement can not only make full use of the space in the frame 2, which is conducive to reducing the width of the frame 2, but also facilitate the production and manufacturing of the display panel.

[0048] In one embodiment, Figure 2 or Figure 3As shown, the multiple first wirings 111 located in the frame 2 are arranged in the same layer as the touch sensing layer 11, and the multiple second wirings 121 located in the frame 2 are arranged in the same layer as the fingerprint sensing layer 12. That is, the multiple first wirings 111 are led out from the touch sensing layer 11 along the horizontal plane, and the multiple second wirings 121 are led out from the fingerprint sensing layer 12 along the horizontal plane, which not only facilitates the production and manufacturing of the display panel, but also avoids changing the positions of the multiple first wirings 111 and the multiple second wirings 121 through other insulating layers, which is conducive to thinning the display panel. It can be understood that in this embodiment, the touch sensing layer 11 and the fingerprint sensing layer 12 are stacked.

[0049] Figure 4 FIG. 1 is a partial perspective view of a display panel according to an exemplary embodiment of the present disclosure. Figure 4 In FIG. 1 , the dotted line represents the first wiring 111 , and the solid line represents the second wiring 121 .

[0050] In one embodiment, Figure 4 As shown, at least part of the plurality of first wirings 111 located in the frame 2 and at least part of the plurality of second wirings 121 located in the frame 2 are extended along the length direction of the frame 2, and the length direction is the extension direction of the side wall of the frame. Figure 1 The length L1 and the length L2 in the figure, several first lines 111 extend along the length L1 direction, and then extend along the length L2 direction, and several second lines 121 extend along the length L1 direction, and then extend along the length L2 direction. When the lengths of the multiple first lines 111 and the multiple second lines 121 are long, they can be arranged along the length direction of the frame 2 to reduce the area occupied in the width direction of the frame 2, which is conducive to reducing the width of the frame 2. When the lengths of the multiple first lines 111 and the multiple second lines 121 are short, they can also be arranged along the width direction of the frame 2, referring to Figure 1 The width X1 and the width X2 in the figure, the first wirings 111 and the second wirings 121 are all extended along the width X2 direction.

[0051] Figure 5 FIG. 1 is a partial perspective view of a display panel according to an exemplary embodiment of the present disclosure. Figure 6 FIG. 1 is a partial perspective view of a display panel according to an exemplary embodiment of the present disclosure. Figure 5 and Figure 6 In FIG. 1 , the dotted line represents the first wiring 111 , and the solid line represents the second wiring 121 .

[0052] The present disclosure provides the following examples regarding the positions of the plurality of first routing lines 111 and the plurality of second routing lines 121:

[0053] like Figure 1As shown, the frame 2 includes: a first frame 21, a second frame 22 opposite to the first frame 21, and a third frame 23 disposed between the first frame 21 and the second frame 22. Figure 4 As shown, at least part of the plurality of first lines 111 is disposed in the first frame 21 and extends to the third frame 23. At least part of the plurality of second lines 121 is disposed in the second frame 22 and extends to the third frame 23. In this way, not only is it beneficial to make the widths of the first frame 21 and the second frame 22 equal, making the appearance of the display panel beautiful, but also the mutual interference between the first lines 111 and the second lines 121 is reduced.

[0054] and / or, if Figure 5 and Figure 6 As shown, at least part of the plurality of first traces 111 is disposed in the second frame 22 and extends to the third frame 23. At least part of the plurality of second traces 121 is disposed in the first frame 21 and extends to the third frame 23. When a part of the plurality of first traces 111 is disposed in the first frame 21 and another part is disposed in the second frame 22, and a part of the plurality of second traces 121 is disposed in the first frame 21 and another part is disposed in the second frame 22, it is beneficial to make the widths of the first frame 21 and the second frame 22 equal.

[0055] and / or, if Figure 4 , Figure 5 or Figure 6 As shown, at least part of the plurality of first wirings 111 and at least part of the plurality of second wirings 121 are disposed in the third frame 23. When the lengths of the first wirings 111 and the second wirings 121 are short, they can be directly led into the third frame 23.

[0056] In addition, when the lengths of the first and second traces 111 and 121 are short, each first trace 111 can be completely disposed in the first frame 21 or the second frame 22, and each second trace 121 can be completely disposed in the first frame 21 or the second frame 22. When the number of the first and second traces 111 and 121 is large and the lengths are long, they can be led to the third frame 23, which is beneficial to reducing the widths of the first and second frames 21 and 22.

[0057] In the embodiment of the present disclosure, the first frame 21, the second frame 22, and the third frame 23 may be the left frame, the right frame, and the bottom frame of the display panel, respectively. The "left", "right", and "bottom" are all based on the direction when the user faces the display area 1 of the display panel.

[0058] In one embodiment, Figure 4 , Figure 5 or Figure 6As shown, the display panel provided by the embodiment of the present disclosure also includes: a control unit 3, which is connected to the multiple first wirings 111 and the multiple second wirings 121; the control unit 3 adopts a touch mode to control the touch sensing layer 11 to perform touch operation, and the control unit 3 adopts a fingerprint recognition mode to control the fingerprint sensing layer 12 to perform fingerprint recognition operation, and the touch mode and the fingerprint recognition mode do not work at the same time. Figure 7 FIG. 1 is a scanning timing diagram of a control unit according to an exemplary embodiment of the present disclosure, as shown in FIG.

[0059] Figure 7 As shown, one scanning cycle includes: 11 times of touch scanning, 2 times of noise scanning, and 1 time of fingerprint recognition scanning. That is, the touch mode and the fingerprint recognition mode do not work at the same time, and the control unit 3 adopts a time-sharing working mode to perform the touch mode and the fingerprint recognition mode. Among them, the multiple first wires 111 of the touch sensing layer 11 and the multiple second wires 121 of the fingerprint sensing layer 12 can be connected through a multiplexer or a multi-way switch, and the control unit 3 controls the multiplexer or the multi-way switch to switch between the touch sensing layer 11 and the fingerprint sensing layer 12. Among them, the control unit 3 can be arranged on a flexible circuit board to be suitable for frames 2 of different shapes.

[0060] like Figure 4 or Figure 5 As shown, the control unit 3 can be arranged in the third frame 23, and the plurality of first traces 111 can extend to the third frame 23 along the length direction of the first frame 21 or the second frame 22, and be connected to the control unit 3. The control unit 3 can also include two sub-control units, which are arranged on both sides of the third frame 23 close to the first frame 21 and the second frame 22, see Figure 6 One sub-control unit is connected to the wiring extending from the first frame 21, and the other sub-control unit is connected to the wiring extending from the second frame 22. This reduces the length of the first wiring 111 and the second wiring 121 extending to the third frame 23, which is conducive to reducing the width of the third frame 23.

[0061] The time-sharing control mode is used to control the touch sensing layer 11 and the fingerprint sensing layer 12 to work, which requires time-sharing scanning, which reduces the touch scanning time and reduces the signal-to-noise ratio. Based on this, in one embodiment, Figure 3As shown, the display panel provided by the embodiment of the present disclosure also includes: a first control unit 4, which is arranged in the frame 2 and connected to the plurality of first wirings 111, and is used to control the touch sensing layer 11 to perform touch operation. A second control unit 5 is arranged in the frame 2 and connected to the plurality of second wirings 121, and is used to control the fingerprint sensing layer 12 to perform fingerprint recognition. In this way, it is beneficial for the first control unit 4 to fully perform touch scanning and the second control unit 5 to fully perform fingerprint recognition scanning. Among them, the first control unit 4 can be arranged on a first flexible circuit board, and the second control unit 5 can be arranged on a second flexible circuit board. The first control unit 4 and the second control unit 5 can be arranged on different layers in the frame 2 to avoid being arranged on the same layer and occupying a larger area, which is beneficial to reducing the width of the frame 2 and increasing the screen-to-body ratio.

[0062] In one embodiment, the fingerprint sensing layer 12 is stacked with the touch sensing layer 11, and the fingerprint sensing layer 12 covers part or all of the touch sensing layer 11. The fingerprint sensing layer 12 can be provided in any area on the touch sensing layer 11, and the fingerprint sensing layer 12 can include one or more areas. When the fingerprint sensing layer 12 covers the entire touch sensing layer 11, this gives the display panel a full-screen fingerprint recognition function, making it convenient for users to touch different positions for fingerprint recognition.

[0063] In one embodiment, Figure 2 As shown, the display area 1 is further provided with a flexible display screen 13, which is provided on the side of the touch sensing layer 11 and the fingerprint sensing layer 12 away from the outer surface of the display area 1, and the display surface of the flexible display screen 13 faces the touch sensing layer 11 and the fingerprint sensing layer 12. In this way, the display panel can be a flexible display panel, so as to be applied to terminal devices including folding screens and fixed bend screens.

[0064] Figure 8 FIG. 1 is a schematic diagram showing a structure of a display module of a display panel according to an exemplary embodiment of the present disclosure. Fig. 9 FIG. 1 is a schematic diagram of a structure of a display module of a display panel according to an exemplary embodiment of the present disclosure. Figure 8 or Fig. 9 As shown, the display area 1 is further provided with a polarizing layer 14, which is arranged on the side of the touch sensing layer 11 away from the flexible display screen 13. The polarizing layer 14 polarizes the light, which is beneficial to the effective display of the display area 1. The fingerprint sensing layer 12 is arranged between the touch sensing layer 11 and the polarizing layer 14. Fig. 9 Or, the fingerprint sensing layer 12 is disposed on the side of the polarizing layer 14 away from the touch sensing layer 11, see Figure 8 That is, the fingerprint sensing layer 12 is closer to the outer surface of the display area 1 than the touch sensing layer 11, which is beneficial to improve the sensitivity of fingerprint recognition.

[0065] Fig.10FIG. 1 is a schematic diagram of a structure of a display module of a display panel according to an exemplary embodiment of the present disclosure. In one embodiment, Fig. 9 and 10 As shown, the display panel provided by the embodiment of the present disclosure also includes: a transparent cover plate layer 15, which is arranged at the outermost layer of the display area 1, and the cover plate layer 15 includes: at least two layers of transparent cover plates 151. By providing at least two layers of transparent cover plates 151, the surface of the display panel is flat and it is also endowed with good mechanical strength. Among them, the two adjacent cover plates 151 can be connected by a transparent adhesive layer 16, and the transparent adhesive layer 16 can be an OCA (Optically Clear Adhesive) adhesive layer, and the OCA adhesive layer has good light transmittance. Among them, the cover plate 151 can be two layers, and the cover plate 151 can be a flexible cover plate or a rigid cover plate. When the cover plate 151 is a flexible cover plate, the display panel can be manufactured in the order of the flexible display screen 13 to the cover plate 151. When the cover plate 151 is a rigid cover plate, the display panel can be manufactured in the order of the cover plate 151 to the flexible display screen 13. The material of the cover plate 151 can be PI (Polyimide) or glass. Other film layers may also be connected via a transparent adhesive layer 16 , for example, a transparent adhesive layer 16 is provided between the cover plate 151 and the polarizing layer 14 , and a transparent adhesive layer 16 is provided between the touch sensing layer 11 and the flexible display screen 13 .

[0066] In one embodiment, Fig.10 As shown, the fingerprint sensing layer 12 is disposed on the non-outermost cover plate 151, so that the outermost cover plate 151 protects the fingerprint sensing layer 12 and makes the fingerprint sensing layer 12 have good sensitivity. The cover plate 151 can be used as a substrate of the fingerprint sensing layer 12, and the fingerprint sensing layer 12 can be directly manufactured and formed on the cover plate 151.

[0067] In one embodiment, the fingerprint sensing layer 12 is a capacitive fingerprint sensing layer, which avoids punching holes in the support layer on the side of the flexible display screen 13 away from the display surface, and is beneficial to the flatness and aesthetics of the display panel surface.

[0068] An embodiment of the present disclosure further provides a terminal device, which includes any one of the display panels mentioned above.

[0069] In the embodiments of the present disclosure, the terminal device may be a mobile phone, a digital broadcast terminal, a message sending and receiving device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc.
