[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0063] Based on the above technical problems, this embodiment proposes the following solutions:

[0064] Figure 1 It is a structural schematic diagram of a display module provided by an embodiment of the present invention. Figure 2It is a schematic structural diagram of another display module provided by an embodiment of the present invention. Figure 3 FIG. 1 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Figures 1 to 3 , the present embodiment provides a display module 400 including a display area 10 and a non-display area 20 at least partially surrounding the display area; the display module further includes: a bending area 1, located in the non-display area 20; a shift register circuit 2, the shift register circuit 2 is arranged in the non-display area 20; a pixel circuit 3, arranged in the display area 10; a conductive connecting line 4, connected between the shift register circuit 2 and the pixel circuit 3, the conductive connecting line 4 extends from the non-display area 20 to the display area 10; continue to see Figure 3 , along the first direction Y, the shift register circuit 2 is arranged between the display area 10 and the bending area 1, and / or, continue to refer to Figure 1 , the shift register circuit 2 is arranged on a side of the bending area 1 away from the display area 10 ; the first direction Y is an extension direction of the display area 10 toward the non-display area 20 .

[0065] Specifically, the display area 10 is provided with a pixel circuit 3 and a light-emitting element (not shown in the figure). The pixel circuit 3 drives the light-emitting element to emit light. The light-emitting element emits light under the drive of the pixel circuit 3 to display the picture. The non-display area 20 is not provided with a light-emitting element. The non-display area 20 is not used to display the picture. The bending area 1 is used to bend the circuit of the non-display area 20 of the display module 400 to the back of the display module 400. The back of the display module 400 can be the non-light-emitting surface of the display module 400. A driving chip or a flexible circuit board is bound to the back of the display module 400. For the display module 400 bound with a flexible circuit board, the driving chip can be set on the flexible circuit board.

[0066] By providing the bending area 1 in the non-display area 20, the circuit of the non-display area 20 can be bent to the back of the display module 400, so that the frame of the non-display area 20 is narrower. The display module 400 may also include a left frame and a right frame. The left frame and the right frame of the display module 400 are both arranged adjacent to the non-display area 20.

[0067] Since the left and right frames of the existing display module are provided with shift register circuits, and since the size of the shift register circuits is large and the circuits are numerous, the left and right frames of the existing display module are relatively wide. The shift register circuit is referred to as a GIP circuit (Gate in panel) in some embodiments. The present application arranges the shift register circuit 2 in the non-display area 20, and the non-display area 20 is located at the bottom frame position of the display module. The shift register circuit 2 may not be arranged in the left and right frames, thereby effectively reducing the size of the non-display area 20 occupied by the shift register circuit 2 in the left and right frames, thereby realizing an extremely narrow frame or borderless design of the left and right frames.

[0068] The shift register circuit 2 located in the non-display area 20 is connected to the pixel circuit 3 located in the display area through the conductive connecting line 4. Along the first direction Y, the conductive connecting line 4 extends from the non-display area 20 to the display area 10. The conductive connecting line 4 is connected to the pixel circuit 3 in the display area 10. The timing control signal generated by the shift register circuit 2 is transmitted to the pixel circuit 3 in the display area through the conductive connecting line 4. The pixel circuit 3 drives the light-emitting element to emit light according to the timing control signal to display the picture. The timing control signal generated by the shift register circuit 2 may include a scan signal and / or a light control signal. The conductive connecting line 4 may include at least one scan line and / or at least one light control line.

[0069] Continue to see Figure 3 Along the first direction Y, the shift register circuit 2 is arranged between the display area 10 and the bending area 1, which facilitates the conductive connecting line 4 to extend to the display area 10, simplifies the wiring, and can also reduce the width of the left and right frames of the display module 400.

[0070] Continue to see Figure 1 Along the first direction Y, the shift register circuit 2 is arranged on the side of the bending area 1 away from the display area 10. This arrangement allows the shift register circuit 2 to be bent to the back of the display module 400 in the non-display area 20, thereby further making the frame of the non-display area 20 of the display module 400 narrower.

[0071] Continue to see Figure 2 , at least part of the shift register circuit 2 can be arranged along the first direction Y between the display area 10 and the bending area 1, and at least part of the shift register circuit 2 can be arranged on the side of the bending area 1 away from the display area 10, so that the non-display area 20 can have more space to be arranged, so that both the conductive connecting line 4 and the shift register circuit 2 can have enough wiring space, and the shift register circuit 2 will not occupy too much border width of the non-display area 20, further reducing the width of the border of the non-display area 20 of the display module 400.

[0072] The display module 400 provided in this embodiment, by setting the shift register circuit 2 in the non-display area 20, since the non-display area 20 is provided with the bending area 1, the setting of the shift register circuit 2 will not affect the width of the frame of the non-display area 20, and can also improve the width of the left frame and the right frame of the display module 400. By setting the shift register circuit 2 between the display area and the bending area 1 along the first direction Y, and / or the shift register circuit 2 is set on the side of the bending area 1 away from the display area, the non-display area 20 can have more space to set the shift register circuit 2, and the conductive connection line 4 has enough wiring space, thereby reducing the width of the left frame and the right frame of the display module 400, so that the display module 400 can be realized without the left frame and the right frame.

[0073] It should be noted that, for a display module without a bending area, the shift register circuit can be arranged in the non-display area, and the display module can also include a power signal line, the power signal line is at least partially located in the non-display area, and the orthographic projection of the shift register circuit on the power signal line can be at least partially overlapped with the orthographic projection of the power signal line located in the non-display area, or completely staggered. The shift register circuit is arranged in the non-display area, which can effectively reduce the width of the left and right borders of the display module, and no limitation is made here.

[0074] Optionally, based on the above embodiment, Figure 4 It is a structural schematic diagram of another display module provided by an embodiment of the present invention. Figure 5 It is a structural schematic diagram of another display module provided by an embodiment of the present invention. Figure 6 FIG. 1 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Figures 4 to 6 , the display module 400 may further include a fan-out area 5. Along the first direction Y, the fan-out area 5 is located in the non-display area 20 and is arranged on at least one side of the bending area 1. Along the first direction Y, the shift register circuit 2 is located between the fan-out area 5 and the bending area 1, and / or, the shift register circuit 2 is located on the side of the fan-out area 5 away from the bending area 1; along the second direction Z, the orthographic projection of the shift register circuit 2 in the fan-out area 5 at least partially overlaps with the fan-out area 5, or the orthographic projection of the shift register circuit 2 in the fan-out area 5 is staggered with the fan-out area 5; the second direction Z is the thickness direction of the display module 400.

[0075] Specifically, the fan-out area 5 is used to fan out the signal lines of the display area 10 of the display module 400 and the signal lines of the non-display area 20 to the non-display area 20. The fanned-out signal lines can be bound and connected with the driver chip or the flexible circuit board in the binding area. Since the size of the driver chip IC is narrower than that of the display module 400, the signal lines are fanned out through the fan-out area 5, which facilitates the binding of the driver chip IC.

[0076] An optional setting method, continue to see Figure 4 Along the first direction Y, the shift register circuit 2 is arranged between the fan-out area 5 and the bending area 1. In this way, the shift register circuit 2 can effectively utilize the fan-out space of the non-display area 20.

[0077] Another optional setting method is to continue combining Figure 5 and Figure 6 , along the first direction Y, the shift register circuit 2 is arranged on the side of the fan-out area 5 away from the bending area 1. This arrangement, on the one hand, can facilitate the wiring of the conductive connection line 4. On the other hand, the shift register circuit 2 is arranged on the side of the fan-out area 5 away from the bending area 1, so that the layout shape of the shift register circuit 2 is not restricted, which is more conducive to saving the frame size of the non-display area 20.

[0078] Another optional implementation method, continue to combine Figures 4 to 6 Along the first direction Y, at least part of the shift register circuit 2 is arranged between the fan-out area 5 and the bending area 1, and at least part of the shift register circuit 2 is located on the side of the fan-out area 5 away from the bending area 1. This arrangement can further increase the setting space of the shift register circuit 2, and on the premise of reducing the left and right frames of the display module 400, the width of the frame of the non-display area 20 can be further reduced.

[0079] Optional, Figure 7 It is a structural schematic diagram of another display module provided by an embodiment of the present invention. Figure 8 FIG. 1 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Figure 7 and Figure 8 The fan-out region 5 includes: a first fan-out region 51, along the first direction Y, the first fan-out region 51 is located between the bending region 1 and the display region 10; see Figure 7 , along the first direction Y, the shift register circuit 2 is arranged between the first fan-out area 51 and the display area 10; and / or, see Figure 8 , the shift register circuit 2 is arranged between the first fan-out area 51 and the bending area 1; and / or, along the second direction Z, the positive projection of the shift register circuit 2 in the first fan-out area 51 at least partially overlaps with the first fan-out area 51.

[0080] Specifically, along the first direction Y, the first fan-out area 51 is disposed between the display area and the bending area 1. The data line DATA located in the first fan-out area 51 directly leads all the data lines DATA located in the display area to the first fan-out area 51. In the first fan-out area 51, the plurality of data lines DATA transmit the data signal to the data line DATA in the bending area 1 through a specific layout and connection method. This layout not only facilitates the rapid transmission of the data signal, but also enables the bending area 1 to be narrow in size while ensuring the display effect.

[0081] Continue to see Figure 7 Along the first direction Y, the shift register circuit 2 is arranged between the first fan-out area 51 and the display area 10, so that the distance between the shift register circuit 2 and the display area 10 is relatively close, which is convenient for wiring the conductive connection line 4 connected to the shift register circuit 2.

[0082] Continue to see Figure 8 Along the first direction Y, the shift register circuit 2 is arranged between the first fan-out area 51 and the bending area 1, so that the first fan-out area 51 can reserve part of the space for arranging the shift register circuit 2. This arrangement increases the arrangement space of the shift register circuit 2.

[0083] Along the second direction Z, the orthographic projection of the shift register circuit 2 in the first fan-out area 51 at least partially overlaps with the first fan-out area 51 , which can further increase the arrangement space of the shift register circuit 2 and achieve the design requirement of a narrow frame of the non-display area 20 .

[0084] Optionally, based on the above embodiments, continue to refer to Figure 4 The fan-out region 5 includes: a second fan-out region 52, along the first direction Y, the second fan-out region 52 is located on the side of the bending region 1 away from the display region 10; continue to see Figure 4 , along the first direction Y, the shift register circuit 2 is arranged between the second fan-out area 52 and the bending area 1; and / or, continue to refer to Figure 5 and Figure 6 , the shift register circuit 2 is arranged on a side of the second fan-out area 52 away from the bending area 1; and / or, the orthographic projection of the shift register circuit 2 in the second fan-out area 52 at least partially overlaps with the second fan-out area 52.

[0085] Specifically, the second fan-out area 52 is arranged on the side of the bending area 1 away from the display area 10. The second fan-out area 52 further fans out the signal lines of the bending area 1, which can further reduce the width occupied by each signal line. The second fan-out area 52 can be bent to the back of the display module 400 to achieve a narrow frame of the non-display area 20.

[0086] By setting the shift register circuit 2 between the second fan-out area 52 and the bending area 1 along the first direction Y; and / or, the shift register circuit 2 is set on the side of the second fan-out area 52 away from the bending area 1; and / or, the positive projection of the shift register circuit 2 on the second fan-out area 52 overlaps the second fan-out area 52 at least partially, the wiring space of the shift register circuit 2 can be increased. In this way, the left and right frames of the display module 400 are narrow, and the shift register circuit 2 is also bent to the back of the display module 400, which does not increase the frame width of the non-display area 20, and realizes the narrow frame of the display module 400.

[0087] An optional implementation manner, based on the above embodiments, Fig. 9 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Fig. 9 The display module 400 may include both the first fan-out area 51 and the second fan-out area 52. The shift register circuit 2 may be disposed in one or at least two of the above-mentioned areas of the non-display area 20, or may be evenly distributed in the above-mentioned areas of the non-display area 20, without any limitation.

[0088] Optionally, based on the above embodiments, Fig.10 FIG. 1 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Fig.10, the shift register circuit 2 includes at least one group of first shift register circuits 21; the conductive connecting line 4 includes a scan line SCAN; the first shift register circuit 21 is connected to the scan line SCAN; the scan line SCAN is connected to the pixel circuit 3; and / or, the shift register circuit 2 includes at least one group of second shift register circuits 22; the conductive connecting line 4 includes a light-emitting control line EM; the light-emitting control line EM is connected to the pixel circuit 3; the second shift register circuit 22 is connected to the light-emitting control line EM.

[0089] Specifically, the first shift register circuit 21 is used to generate a scan signal. Exemplarily, the scan signal may include a first scan signal and a second scan signal with different timings. The first shift register circuit 21 is connected to a scan line SCAN. The scan line SCAN transmits the scan signal to the pixel circuit 3.

[0090] The second shift register circuit 22 is used to generate a light emitting control signal. Exemplarily, the light emitting control signal may include a first light emitting control signal and a second light emitting control signal. The second shift register circuit 22 is connected to the light emitting control line EM. The light emitting control line EM transmits the light emitting control signal to the pixel circuit 3.

[0091] Optionally, based on the above embodiments, continue to refer to Fig.10 When the shift register circuit 2 includes a first shift register circuit 21 and a second shift register circuit 22, along the first direction Y, the first shift register circuit 21 and the second shift register circuit 22 are alternately arranged.

[0092] Specifically, a group of first shift register circuits 21 is arranged along the third direction X. Each group of first shift register circuits 21 may include at least two first shift register circuits 21. In this arrangement, the input signal of the first shift register circuit 21 can be input to the first-level unit of the first shift register circuit 21 from the left and right sides.

[0093] Along the first direction Y, a group of second shift register circuits 22 is arranged on a side of the first shift register circuit 21 close to the display area, or on a side of the first shift register circuit 21 far from the display area. Each group of second shift register circuits 22 may include at least two second shift register circuits 22. In this way, the input signal of the second shift register circuit 22 can be input to the first-level unit of the second shift register circuit 22 from the left and right sides.

[0094] Along the first direction Y, the first shift register circuit 21 and the second shift register circuit 22 are alternately arranged. This arrangement, on the one hand, facilitates the alternating wiring of the scan line SCAN and the light-emitting control line EM; on the other hand, the first shift register circuit 21 and the second shift register circuit 22 can be set to be greater than one row to meet the requirements of bilateral driving of the pixel circuit 3 in the display area.

[0095] Optional, Fig.11 It is a structural schematic diagram of another display module provided by an embodiment of the present invention. Fig.12 FIG. 1 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Fig.11 and Fig.12 When the conductive connection line 4 includes a scan line SCAN and a light-emitting control line EM, at least one scan line SCAN and at least one light-emitting control line EM are alternately arranged along a third direction X; and the third direction X is perpendicular to both the first direction Y and the second direction Z.

[0096] Specifically, the third direction X may be a row direction of the pixel circuit 3. At least one scan line SCAN and at least one light-emitting control line EM are alternately arranged along the third direction X, so as to save wiring space. Since each pixel unit is connected to both the scan line SCAN and the light-emitting control line EM, at least one scan line SCAN and at least one light-emitting control line EM are alternately arranged along the third direction X, so as to facilitate unified wiring of the scan line SCAN and the light-emitting control line EM connected to the pixel circuit 3 in the same row, thereby reducing the difficulty of winding.

Fig.10 , Fig.13 and Fig.14 The display module 400 further includes: a substrate 30; a data line DATA disposed on one side of the substrate 30, the data line DATA extending from the display area 10 to the non-display area 20; the data line DATA located in the fan-out area 5 and the bending area 1; along the second direction Z, at least part of the conductive connection line 4 is disposed on the side of the data line DATA away from the substrate 30, and / or, at least part of the conductive connection line 4 is disposed in the same layer as the data line DATA. Optionally, along the third direction X, the orthographic projection of the conductive connection line 4 on the substrate 30 is directly opposite to or at least partially offset from the orthographic projection of the data line DATA on the substrate 30.

[0098] Specifically, the second direction Z may be the thickness direction of the display module 400. The data line DATA is connected to the driver chip IC. The data line DATA is used to transmit the data voltage to the pixel circuit 3. Along the second direction Z, at least part of the conductive connection line 4 is arranged on the side of the data line DATA away from the substrate 30, so that the conductive connection line 4 is wired on a conductive layer on the side of the data line DATA away from the substrate 30, and the wiring space is sufficient, and there will be no wiring space conflict, and it is easy to be compatible with the existing conductive layer of the display module 400, reducing the process difficulty.

[0099] An optional arrangement is to arrange at least part of the conductive connection lines 4 and the data lines DATA in the same layer. This arrangement can increase the wiring position of the conductive connection lines 4 and reduce the thickness of the display module 400 .

[0100] Another optional setting method is to set part of the conductive connecting lines 4 on the side of the data lines DATA away from the substrate 30, and set part of the conductive connecting lines 4 on the same layer as the data lines DATA, which can further increase the wiring positions of the conductive connecting lines 4 and provide sufficient wiring space for the display module 400 with a narrower display area 10 between the left frame and the right frame, such as applications in vertical screens.

[0101] Optionally, based on the above embodiments, Fig.15 It is a structural schematic diagram of another display module provided by an embodiment of the present invention. Fig.16 FIG. 1 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Fig.15 and Fig.16 The conductive connection line 4 may include: a first conductive segment 41, a second conductive segment 42 and a third conductive segment 43; the first conductive segment 41 is located in the non-display area 20, extends along the first direction Y, and is connected to the shift register circuit 2; the second conductive segment 42 is located in the display area 10, at least partially extends along the first direction Y, and is connected to the first conductive segment 41; the third conductive segment 43 is located in the display area 10, extends along the third direction X, and is respectively connected to the second conductive segment 42 and the pixel circuit 3.

[0102] Specifically, the first conductive segment 41 of the conductive connection line 4 is disposed in the non-display area 20. Along the first direction Y, the first end of the first conductive segment 41 is connected to the shift register circuit 2, and the second end of the first conductive segment 41 is connected to the first end of the second conductive segment 42. The second end of the second conductive segment 42 is connected to the first end of the third conductive segment 43. The second end of the third conductive segment 43 is connected to the pixel circuit 3. The second conductive segment 42 is located in the display area 10. The third conductive segment 43 extends along the third direction X. The third conductive segment 43 is connected to the pixel unit. See more Fig.15The third conductive segment 43 can reuse the scan line SCAN or the light emitting control line EM extending along the third direction X of the display module 400 .

[0103] Continue to see Fig.15 , the second conductive segment 42 may extend along the first direction Y. Alternatively, see Fig.16 The second conductive segment 42 may extend partially along the first direction Y and partially along the third direction X. When the second conductive segment 42 extends along the first direction Y, the second conductive segment 42 and the third conductive segment 43 may be connected by punching, which simplifies wiring and reduces process difficulty.

[0104] When the second conductive segment 42 partially extends along the first direction Y and partially extends along the third direction X, the second conductive segment 42 is connected to the two side edges of the third conductive segment 43 close to the left frame and the right frame. This arrangement can minimize the difference between the display effect of the display module 400 and the display effect of the existing display module 400 in which the shift register circuit 2 is arranged at the left frame and the right frame, so that the display effect of the display module 400 is better.

[0105] Optionally, based on the above embodiments, continue to refer to Fig.16 The display area 10 is divided into a first display area 101 and a second display area 102 by a central axis L1, and the central axis L1 extends along a first direction Y; at least one second conductive segment 42 located in the first display area 10 and at least one second conductive segment 42 located in the second display area 10 are symmetrically arranged with the central axis L1 as a symmetry axis. Optionally, the second conductive segments 42 connected to the third conductive segments 43 located in different rows do not overlap.

[0106] Specifically, at least one second conductive segment 42 located in the first display area 10 and at least one second conductive segment 42 located in the second display area 10 are symmetrically arranged with the central axis L1 as the symmetry axis, which can improve the display uniformity of the first display area 10 and the second display area 10 of the display module 400 and further improve the display effect of the display module 400.

[0107] The second conductive segments 42 connected to the third conductive segments 43 located in different rows are arranged not to overlap. On the one hand, the signal interference problem caused by the overlap of signal lines can be reduced; on the other hand, the thickness of the third conductive segments 43 and the second conductive segments 42 along the second direction Z can be reduced, thereby reducing the thickness of the display module 400.

[0108] Optionally, based on the above embodiments, continue to refer to Fig.16, the second conductive segment 42 includes a first sub-conductive segment 421, the first sub-conductive segment 421 extends along the first direction Y, the first sub-conductive segment 421 is connected to the first conductive segment 41, and the first sub-conductive segment 421 is connected to the third conductive segment 43; or, the second conductive segment 42 includes a first sub-conductive segment 421 and a second sub-conductive segment 422, the first sub-conductive segment 421 extends along the first direction Y, and the second sub-conductive segment 422 extends along the third direction X; the first sub-conductive segment 421 is connected to the first conductive segment 41, and the second sub-conductive segment 422 is connected between the first sub-conductive segment 421 and the third conductive segment 43.

[0109] Specifically, the first sub-conductive segment 421 extending along the first direction Y is directly connected to the third conductive segment 43, and the wiring is simple and easy to implement. The second sub-conductive segment 422 extending along the third direction X is connected to the first sub-conductive segment 421 extending along the first direction Y, and the first sub-conductive segment 421 extending along the first direction Y is connected to the third conductive segment 43 through the second sub-conductive segment 422 extending along the third direction X. In this way, it is convenient to connect the third conductive segment 43 to the scanning signal or the light control signal at the two side edges close to the left frame and the right frame, so that the display effect of the display module 400 is consistent with the display effect of the existing display module 400 in which the shift register circuit 2 is set at the left frame and the right frame, thereby improving the display effect of the display module 400.

[0110] Optionally, based on the above embodiments, continue to refer to Fig.16 , the first sub-conductive segments 421 connected to the third conductive segments 43 located in different rows are parallel to each other; optionally, the second sub-conductive segments 422 connected to the third conductive segments 43 located in different rows are parallel to each other.

[0111] Specifically, such an arrangement facilitates regular winding between each first sub-conductive segment 421 and each second sub-conductive segment 422 , reduces mutual interference between adjacent signal lines, saves the length of the first sub-conductive segment 421 and the second sub-conductive segment 422 , and reduces costs.
