Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a terminal device. Background Art

[0002] As electronic devices become more versatile and people use them in more diverse scenarios, they have higher requirements for the portability of electronic devices.

[0003] Designing electronic devices to be thin and lightweight is a key approach to improving their portability. However, electronic devices contain numerous electronic components, such as microphones, speakers, power connectors, and display panels. Assembling these components requires ensuring they do not interfere with each other, which limits further reductions in thickness. Utility Model Content

[0004] Embodiments of the present application provide a display panel and a terminal device to solve the problem of how to further reduce the thickness of the terminal device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a display panel, which includes a display portion and a back-folding portion, the back-folding portion includes a fixed portion and a bending portion, after the back-folding portion is bent, the fixed portion is arranged roughly parallel to the display portion, and the bending portion connects the display portion and the fixed portion; wherein, the back-folding portion is provided with at least one first opening, and the first opening is located in the fixed portion and / or the bending portion.

[0007] In this way, after the back fold is bent, the first opening at least partially overlaps with the display portion in the thickness direction of the display portion. Therefore, when the terminal device is installed, the electronic components of the terminal device can overlap with the first opening in the thickness direction of the display portion. The portion of the electronic component that overlaps with the first opening will not be interfered with by the back fold in the thickness direction of the display portion. Therefore, while ensuring the distance between the electronic component and the back fold in the thickness direction of the display portion, the size occupied by the electronic component and the display panel in the thickness direction of the display portion can be reduced. In fact, at least a portion of the electronic component can also be arranged in the first opening to further reduce the size occupied by the electronic component and the display panel in the thickness direction of the display portion. This is conducive to reducing the thickness of the terminal device.

[0008] In one possible implementation of the first aspect, the back fold includes a fixed portion and a bent portion. After the back fold is bent, the fixed portion is disposed substantially parallel to the display portion, and the bent portion connects the display portion and the fixed portion. The first opening is disposed in the fixed portion. Thus, when the electronic component is disposed only below the fixed portion of the back fold, the position of the first opening can be restricted to the fixed portion of the back fold. This ensures that the electronic component does not interfere with the back fold while minimizing the area of ​​the first opening and reducing the impact of the first opening on the layout of fan-out traces on the back fold.

[0009] In one possible implementation of the first aspect, the fixed portion includes a first panel body and a first back film that are stacked together. After the back-folding portion is bent, the first back film is positioned on a side of the first panel body that is closer to the display portion. The first panel body is provided with a first sub-opening, and the first back film is provided with a second sub-opening. The first sub-opening and the second sub-opening are connected and form at least a portion of the first opening. Thus, the fixed portion may include the first panel body and the first back film, and the first opening may be formed by the first sub-opening provided in the first panel body and the second sub-opening provided in the first back film, such that the first opening is positioned in the fixed portion of the display portion.

[0010] In one possible implementation of the first aspect, the first sub-opening and the second sub-opening have the same shape, and the first sub-opening is larger than or equal to the second sub-opening. This allows the edge of the first sub-opening to be completely located within the area of ​​the first backing film excluding the second sub-opening. Thus, the first backing film provided with the second sub-opening provides support for the edge of the first sub-opening, reducing the impact on the strength of the first panel body caused by the first sub-opening. Furthermore, the first sub-opening is relatively large, providing more space for electronic components.

[0011] In one possible implementation of the first aspect, the display portion includes a second opening, and after the back folding portion is bent, the second opening and the first opening at least partially overlap in the thickness direction of the display portion. In this manner, at least a portion of the electronic component can be disposed within the first and second openings, thereby increasing the overlap between the display panel and the electronic component in the thickness direction of the terminal device and further reducing the size occupied by the display panel and the electronic component in the thickness direction of the terminal device.

[0012] In one possible implementation of the first aspect, the display portion includes a third panel body and a second back film, the second back film being located on a non-display side of the third panel body, the third panel body being provided with a third sub-opening, and the second back film being provided with a fourth sub-opening, the third sub-opening and the fourth sub-opening being connected and forming at least a portion of the second opening. Thus, the second opening is formed by the three panel bodies of the display portion and the second back film.

[0013] In one possible implementation of the first aspect, the display portion further includes a supporting film, the supporting film being located on a side of the second back film away from the third panel body, the supporting film being provided with a fifth sub-opening, the third sub-opening, the fourth sub-opening, and the fifth sub-opening being connected and forming at least a portion of the second opening. Thus, the second opening is formed by the three-panel body of the display portion, the second back film, and the supporting film.

[0014] In one possible implementation of the first aspect, after the back fold is bent, the edge of the second opening is located inside the edge of the first opening along the thickness direction of the display portion. This facilitates the extension of the electronic component from the first opening into the second opening and reduces restrictions on the placement of the electronic component.

[0015] In a possible implementation of the first aspect, the center line of the second opening coincides with the center line of the first opening, thereby avoiding misalignment of the first opening and the second opening, thereby facilitating the extension of the electronic component from the first opening to the second opening.

[0016] In one possible implementation of the first aspect, the first opening is located in the fixed portion and the bent portion. The fixed portion includes a first panel body and a first back film that are stacked. After the back folding portion is bent, the first back film is located on a side of the first panel body that is close to the display portion. The display portion includes a third panel body. The bent portion includes a second panel body that connects the first and third panel bodies. A sixth sub-opening is provided on the first and second panel bodies, and a seventh sub-opening is provided on the first back film. The sixth and seventh sub-openings are connected and form at least a portion of the first opening. This provides more space for electronic components that are positioned below the display portion and on a side of the bent portion away from the fixed portion and close to the bent portion.

[0017] In one possible implementation of the first aspect, the display panel further includes a protective film, the protective film covering at least the second panel body; the protective film is provided with a third opening, the third opening communicating with the first opening. Thus, the protective film covering the third panel body also has a third opening, the third opening communicating with the first opening. Therefore, the protective film does not affect the installation of electronic components.

[0018] In one possible implementation of the first aspect, the display panel further includes a driver chip and a fan-out trace disposed in the back fold, one end of the fan-out trace being connected to the display portion, and the other end of the fan-out trace being connected to the driver chip; when the back fold is in a flattened state, the distance from the driver chip to the display portion is greater than the distance from the first opening to the display portion; and at least one fan-out trace is disposed to avoid the first opening. In this manner, the fan-out trace disposed in the back fold maintains its continuity by avoiding the first opening, thereby preventing the first opening from affecting the fan-out trace, and ensuring that the driver chip controls the display portion via the fan-out trace.

[0019] In one possible implementation of the first aspect, at least one fan-out trace includes a first straight segment, a second straight segment, and a relief segment, the relief segment being connected between the first and second straight segments, and extending along a portion of an edge of the first opening. In this manner, the first straight segment can be used to connect the display portion to one of the driver chips, the second straight segment can be used to connect the display portion to the other of the driver chips, and the relief segment connects the first and second straight segments, thereby enabling the fan-out trace to connect the driver chip to the display portion.

[0020] In one possible implementation of the first aspect, the first opening is located within the back fold; alternatively, the first opening is a notch formed on one of two sides of the back fold in a first direction, where the first direction is parallel to a boundary between the back fold and the display portion. In this manner, the position of the first opening in the back fold can be set based on the specific mounting location of the electronic component.

[0021] In a second aspect, the present application provides a terminal device comprising an electronic component and a display panel as described in any one of the first aspects, wherein at least a portion of the electronic component is disposed on the non-display side of the display portion of the display panel; along the thickness direction of the display portion, the electronic component at least partially overlaps with a first opening of the display panel. Thus, along the thickness direction of the terminal device, the first opening provides at least a portion of mounting space for the electronic component, thereby reducing the distance between the electronic component and the back fold of the display panel. At least a portion of the electronic component can even be disposed within the first opening. This reduces the size occupied by the electronic component and the display panel along the thickness direction of the display portion, facilitating a reduction in the thickness of the terminal device.

[0022] In one possible implementation of the second aspect, a dimension of the first opening in the first direction is larger than a dimension of the electronic component in the first direction, and the first direction is parallel to a boundary line between the back fold and the display portion of the display panel. This ensures that the back fold does not interfere with the electronic component in the first direction.

[0023] In one possible implementation of the second aspect, the shape of the portion of the electronic component that overlaps the first opening, as projected onto the plane of the non-display surface of the display portion, matches the shape of the first opening. In this way, the shape of the first opening can be determined based on the shape of the electronic component, thereby minimizing the area occupied by the first opening and reducing the impact of the first opening on the fan-out routing on the back fold.

[0024] In one possible implementation of the second aspect, the display portion includes a second opening. After the back folding portion of the display panel is bent, the second opening intersects with the first opening. Along the thickness direction of the terminal device, the electronic component is at least partially located within the first opening and / or the second opening. In this manner, the position of the electronic component along the thickness direction of the display portion can be flexibly adjusted as needed.

[0025] In one possible implementation of the second aspect, the back-folding portion includes a fixed portion and a bent portion. After the back-folding portion is bent, the fixed portion and the display portion are arranged substantially parallel to each other, and the bent portion connects the display portion and the fixed portion. The terminal device also includes a spacer layer disposed between the display portion and the fixed portion, the spacer layer including a third opening that communicates with the first opening and the second opening. Thus, because the spacer layer also includes the third opening that communicates with the first opening, after the back-folding portion is bent, even if the spacer layer is disposed between the display portion and the fixed portion, the placement of the electronic components is not affected.

[0026] In a possible implementation of the second aspect, the display portion and the fixing portion are both fixedly combined with the spacer layer, thereby ensuring the installation reliability of the binding portion after the terminal device is installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Unless otherwise defined, the technical or scientific terms used in this application should have the usual meanings understood by those skilled in the art. The terms "first", "second", "third" and similar words used in this specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Thus, features defined as "first", "second", and "third" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise stated, "multiple" means two or more.

[0053] The directional terms such as "left", "right", "up" and "down" are defined relative to the orientation of the device schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts. They are used for relative descriptions and clarifications, and they may change accordingly according to changes in the orientation of the chip or semiconductor packaging structure.

[0054] The present application provides a terminal device that can use a flexible screen as a display panel for an electronic device. The flexible screen can be, for example, a flexible organic electroluminescence display (OLED) or a rigid-flexible hybrid organic electroluminescence display (hybrid OLED). The outer lead bonding (OLB) of the flexible screen can be a flexible substrate. The terminal device can be, for example, a smartphone, a tablet terminal, a portable phone terminal, a portable personal computer, an in-vehicle device, a game console, or various other devices.

[0055] The following describes the terminal device using a smartphone as an example. Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the three-dimensional structure of the terminal device 10, Figure 2 For the Figure 1 A possible cross-sectional structure diagram of the A1-A2 line in FIG. For the convenience of explanation, it is specified as follows Figure 1 As shown, a first direction X, a second direction Y, and a third direction Z intersect with each other. For example, the first direction X, the second direction Y, and the third direction Z may intersect with each other at an angle of 90°. The third direction Z may coincide with the thickness direction of the terminal device 10, and the second direction Y and the first direction X may be parallel to surfaces of the terminal device that are disposed opposite to each other in the third direction Z.

[0056] In the following description, a direction toward the tip of an arrow indicating the third direction Z is referred to as “upward”, and a direction opposite to the tip of the arrow is referred to as “downward”.

[0057] The terminal device 10 may include a side frame 11, a display panel 100, and a back cover 16. In the third direction Z, at least a portion of the side frame 11 is disposed between the display panel 100 and the back cover 16. One side of the side frame 11 may extend in the first direction X, and another side connected to the side may extend in the second direction Y. The terminal device 10 may also include electronic components 20 and a mainboard structure 17. The mainboard structure 17 may be disposed between the display panel 100 and the back cover 16. The electronic components 20 may be disposed on the mainboard structure 17 and may also be at least partially located between the display panel 100 and the back cover 16. The electronic components 20 may include a camera 13, a power port 14, a speaker 15, a card slot, buttons, etc. It is understood that the size of these electronic components 20 and any interference between them may affect the thickness of the terminal device 10, thereby limiting the thin and lightweight design of the terminal device 10.

[0058] Please continue to see Figure 2 The display panel 100 may include a back-folding portion 110 and a display portion 120. The display portion 120 may be used to implement the display function of the display panel 100. The back-folding portion 110 may include a fixing portion 113 and a bending portion 114. The bending portion 114 may bend the fixing portion 113 toward the non-display side of the display portion 120, thereby reducing the dimension of the back-folding portion 110 extending on one side of the display portion 120 along the second direction Y. This may reduce the non-display area of ​​the terminal device 10 and increase the screen-to-body ratio of the terminal device 10.

[0059] The display panel 100 may further include a cover glass (CG) 108 . The cover glass 108 may be bonded to the display side of the display portion 120 via an optically clear adhesive (OCA).

[0060] Please continue to see Figures 3 and 4 and combined Figures 1 and 2 , Figure 3 For Figure 2The schematic diagram of the structure of the E1 point observation mainboard structure 17 in the terminal device 10 shown in FIG. Figure 4 For Figure 2 The schematic diagram of the structure of the display panel 100 observed from point E1 in the terminal device 10 is shown. As previously mentioned, the power interface 14 can be provided on the mainboard structural member 17. For example, the power interface 14 can be provided at the bottom edge region of the mainboard structural member 17 along the second direction Y, and in the middle along the first direction X. After the bent portion 114 is bent, the back folding portion 110 is located on one side of the display portion 120 along the second direction Y, and the back folding portion 110 can extend a certain dimension in the first direction X. For example, the dimension of the back folding portion 110 extending in the first direction X is 50% to 80% of the dimension of the terminal device 10 in the first direction X. Therefore, in the terminal device 10, along the third direction Z, the power interface 14 and the back folding portion 110 can at least partially overlap. Among them, the structure and size of the mainboard structural member 17 are only used to illustrate that the setting of the power interface 14 can overlap with the back folding portion 110. The mainboard structural member 17 can also be other structures. For example, the mainboard structural member 17 can be multiple printed circuit boards, and the multiple printed circuit boards can be connected by conductive wires or flexible circuit boards. The power interface 14 can be set on one of the printed circuit boards.

[0061] also, Figure 4 A flexible printed circuit (FPC) 160 is also shown, that is, the display panel 100 may also include a flexible printed circuit 160, one end of the flexible printed circuit 160 is connected to the fixing portion 113, and the other end of the flexible printed circuit 160 is connected to other electrical components. For example, the other end of the flexible printed circuit 160 can be connected to the camera 13 provided on the mainboard structure 17.

[0062] It is understandable that after the bent portion 114 of the back fold 110 is bent, the back fold 110 occupies a certain dimension in the third direction Z. At the same time, the power interface 14 can be located in the center of the terminal device 10 along the third direction Z. After the terminal device 10 is assembled, to ensure that the overlapping portions of the back fold 110 and the power interface 14 in the third direction Z do not interfere with each other, a distance d is required between the back fold 110 and the power interface 14 in the third direction Z during design. This distance d limits the slim and lightweight design of the terminal device 10.

[0063] In another embodiment, see Figure 5 , Figure 5 For the Figure 1 Schematic diagram of another possible cross-sectional structure of the A1-A2 line of the terminal equipment. Figure 5 and Figure 2The difference is that the power interface 14 is no longer located in the middle of the terminal device 10 along the third direction Z, but is instead located offset from the middle position and away from the back fold 110 in the third direction Z. This reduces the thickness of the terminal device 10 while ensuring the spacing distance d between the back fold 110 and the power interface 14 in the third direction Z, achieving a lightweight and thin design. However, the power interface 14 is no longer located in the middle of the terminal device 10 in the third direction Z, that is, the power interface 14 is not centered in the thickness direction of the terminal device. This disrupts the symmetry of the terminal device 10, affects the aesthetics of the terminal device 10, and is inconsistent with user habits.

[0064] In yet another embodiment, see Figures 6 and 7 and combined Figure 1 , the back folding portion 110 and the power interface 14 can be arranged to avoid each other, that is, the back folding portion 110 and the power interface 14 are arranged at the edge areas on different sides of the terminal device. Due to usage habits, the power interface 14 is generally arranged at the edge area at the bottom of the mainboard structure 17 along the second direction Y, that is, the power interface 14 is generally arranged at the short side of the terminal device. Figures 6 and 7 and Figures 3 and 4 The difference is that after the bent portion 114 of the back-folding portion 110 is bent, the back-folding portion 110 can be located to one side of the display portion 120 along the first direction X and extend in the second direction Y. The power interface 14 can still be located at the bottom edge of the mainboard structure 17 along the second direction Y and centered in the third direction Z. In this way, the back-folding portion 110 can be arranged away from the power interface 14 within the XY plane of the first direction X and the second direction Y, thereby avoiding interference between the back-folding portion 110 and the power interface 14, and helping to reduce the thickness of the terminal device 10.

[0065] However, the back fold 110 may still interfere with the electronic components 20 originally positioned on one side of the terminal device 10 along the first direction X. Furthermore, because the display portion 120 is larger in the second direction Y than in the first direction X, placing the back fold 110 on one side of the display portion 120 along the first direction X requires more fan-out traces to control the pixel units of the display portion 120. Because a single driver chip can only connect a limited number of fan-out traces, additional driver chips may be required, increasing manufacturing costs.

[0066] Based on this, see Figures 8A to 11 and combined Figure 1 , the embodiment of the present application provides another terminal device 10 and a display panel 100. Unless otherwise specified below, the terminal device 10 refers to the terminal device 10 provided in the embodiment of the present application. Figure 8A For the Figure 1A possible cross-sectional structure diagram of the A1-A2 line. Figure 8B For the Figure 1 Another possible cross-sectional structure diagram of line A1-A2, Figure 9 This is a schematic diagram of the structure of the mainboard structure 17 observed at point E2 in the terminal device 10. Figure 10 Schematic diagram of the structure of the display panel 100 observed at point E2 in the terminal device 10, Figure 11 for Figure 10 Schematic diagram of the structure of the display panel 100 observed from the display side after being flattened.

[0067] The terminal device 10 differs from the terminal device 10 in the aforementioned embodiment mainly in the display panel 100. The terminal device 10 also includes an electronic component 20 and a display panel 100.

[0068] The display panel 100 includes a back-folding portion 110 and a display portion 120. The back-folding portion 110 includes a fixing portion 113 and a bending portion 114, and the bending portion 114 connects the display portion 120 and the fixing portion 113. After the bending portion 114 is bent, the fixing portion 113 is located on the non-display side of the display portion 120, and the fixing portion 113 is arranged approximately parallel to the display portion 120. The two parts are approximately parallel may mean that the angle between the two parts is within a smaller range, for example, the angle range between the two parts is less than or equal to 15°, such as 0°, 5°, 10° or 15°. In this way, it can be understood that after the back-folding portion 110 is bent, the bending portion 114 is arc-shaped and connects the display portion 120 and the fixing portion 113 which are approximately parallel.

[0069] The back folding portion 110 is provided with at least one first opening 111. Figure 8A The first opening 111 is indicated by a dashed line. In this application, an opening refers to a hollowed-out area. For example, the back fold 110 is provided with a first opening 111, which means that a hollowed-out area is formed on the back fold 110, and the hollowed-out area runs from one side of the back fold 110 to the other side of the back fold 110.

[0070] Since the back folding portion 110 is provided with the first opening 111, the portion of the electronic component 20 that overlaps with the first opening 111 will not be interfered with by the back folding portion 110 in the third direction Z. Therefore, the distance d between the electronic component 20 and the back folding portion 110 along the third direction Z can be ensured (e.g., Figure 8A As shown), the size occupied by the electronic component 20 and the back folding portion 110 in the third direction Z is reduced. Even at least a portion of the electronic component 20 can be arranged in the first opening 111 (as shown). Figure 8B As shown in FIG, the size of the electronic component 20 and the display panel 100 in the third direction Z can be further reduced. This is beneficial for reducing the thickness of the terminal device 10 and thus also for achieving a symmetrical aesthetic design.

[0071] The position of the first opening 111 on the back folding portion 110 is related to the position of the electronic component 20 in the terminal device 10. Figure 9 and Figure 10 and combined Figure 8A When the electronic component 20 is a power interface 14, the electronic component 20 can be centrally located along the first direction X. In this case, the first opening 111 is also centrally located along the first direction X. Figure 12 and Figure 13 and combined Figure 8A When the electronic component 20 is a loudspeaker 15 , the electronic component 20 may be offset along the first direction X, and the first opening 111 is also offset along the first direction X. That is, after the terminal device 10 is assembled, the position of the first opening 111 corresponds to the position of the electronic component 20 .

[0072] See Figure 14 and Figure 15 and combined Figure 8A The number of first openings 111 can also be multiple. The bottom of the terminal device 10 can be provided with multiple electronic components 20. For example, the bottom of the electronic component 20 is provided with both a power interface 14 and a loudspeaker 15. In this case, two first openings 111 can be provided on the back folding portion 110 accordingly.

[0073] Please continue to see Figure 1 and Figure 8A , the electronic component 20 may pass through the side frame 11 on one side of the terminal device 10 in the second direction Y. For example, the electronic component 20 is the power interface 14, which needs to pass through the side frame 11 on one side of the terminal device 10 in order to connect to the external charging cable. After the bending portion 114 is bent, the back folding portion 110 is still at a certain distance from the side frame 11 in the second direction Y. In this case, the part of the electronic component 20 close to the side frame 11 of the terminal device 10 may not interfere with the electronic component 20, but it is necessary to avoid the part of the electronic component 20 away from the side frame 11 of the terminal device 10 from interfering with the first opening 111. Therefore, the position of the first opening is set according to the specific situation of the electronic component 20 extending toward the back folding portion 110 in the second direction Y. For example, if the distance the electronic component 20 extends in the second direction Y is small and only overlaps with the bending portion 114 in the third direction Z, the first opening 111 can be set only at the bending portion 114. For example, if the electronic component 20 extends a greater distance in the second direction Y and overlaps not only the bent portion 114 in the third direction Z but also the fixed portion 113 in the third direction Z, the first opening 111 may be provided in both the bent portion 114 and the fixed portion 113. Alternatively, the electronic component 20 may overlap only with the fixed portion 113 in the third direction Z, in which case the first opening 111 may also be provided only in the fixed portion 113.

[0074] In some embodiments, the size of the first opening 111 in the first direction X may be larger than the size of the electronic component 20 in the first direction X, so that at least a portion of the electronic component 20 can be disposed in the first opening 111, thereby ensuring that the back fold 110 does not interfere with the electronic component 20 in the first direction X, thereby reducing the size occupied by the electronic component 20 and the display panel 100 in the third direction Z. Figure 11 The first direction X may be parallel to a boundary line R between the back folding portion 110 and the display portion 120. The boundary line R between the back folding portion 110 and the display portion 120 may be a straight line, which may be parallel to a row of pixel units of the display portion 120 closest to the back folding portion 110.

[0075] In some embodiments, the shape of the orthographic projection of the portion of the electronic component 20 that overlaps the first opening 111 onto the plane of the non-display surface of the display unit 120 matches the shape of the orthographic projection of the first opening 111 onto the plane of the non-display surface of the display unit 120. Matching the shapes of the two can be understood as having the same shape, but the same or different sizes. For example, both shapes can be circular, but with different diameters. It is understood that the non-display surface of the display unit 120 can be parallel to the XY plane. It is understood that the orthographic projection of the portion of the electronic component 20 that overlaps the first opening 111 can be smaller than the orthographic projection of the first opening 111. In other words, in any direction in the XY plane, the orthographic projection of the portion of the electronic component 20 that overlaps the first opening 111 can be smaller than the orthographic projection of the first opening 111. This application does not limit the shape of the first opening 111. For example, the shape of the first opening 111 can be circular, rectangular, or other shapes. The shape of the first opening 111 can be adaptively configured based on the portion of the electronic component 20 that overlaps the first opening 111.

[0076] The display panel 100 may further include a driver chip 130 disposed on the fixing portion 113. The number of the driver chips 130 may be one or more. Figure 16 , the number of the driver chip 130 is one. The driver chip 130 and the first opening 111 may be arranged in the second direction Y. For example, the first opening 111 is disposed between the driver chip 130 and the display portion 120. For example, see Figure 17 , the number of driver chips 130 is two. The two driver chips 130 may be arranged along the first direction X. Along the first direction X, the first opening 111 may be disposed between the two driver chips 130. In addition, along the first direction X, the first opening 111 may overlap with at least one driver chip 130. The two driver chips 130 may also be disposed on a side of the first opening 111 away from the display portion 120. For example, see Figure 18The number of the driving chips 130 is three. The three driving chips 130 may be arranged along the first direction X, and the three driving chips 130 may be all disposed on a side of the first opening 111 away from the display portion 120 .

[0077] Please continue to see Figure 11 The display panel 100 may further include a fan-out trace 140 provided on the back folding portion 110. One end of the fan-out trace 140 is connected to the display portion 120, and the other end of the fan-out trace 140 is connected to the driver chip 130. In this way, the pixel units in the display portion 120 can be controlled by the driver chip 130. For example, when the back folding portion 110 is in a flat state, the distance from the driver chip 130 to the display portion 120 may be greater than the distance from the first opening 111 to the display portion 120. At this time, the first opening 111 may affect the arrangement of the fan-out trace 140 connecting the driver chip 130 and the display portion 120. Therefore, at least one fan-out trace 140 needs to be arranged to avoid the first opening 111. The fan-out trace 140 disposed on the back fold 110 maintains its own continuity by avoiding the first opening 111, preventing the first opening 111 from affecting the fan-out trace 140, thereby ensuring that the driver chip 130 controls the display portion 120 via the fan-out trace 140. It is understood that the driver chip 130 can also be connected to other components of the terminal device 10, such as the processing unit of the terminal device 10, via the flexible circuit board 160.

[0078] See Figure 19A and Figure 19B , Figure 19A and Figure 19B It is a structural schematic diagram of the back fold portion 110. The at least one fan-out trace 140 arranged to avoid the first opening 111 may include a first straight segment 141, a second straight segment 142 and a avoidance segment 143. The avoidance segment 143 is connected between the first straight segment 141 and the second straight segment 142. The avoidance segment 143 may extend along a portion of the edge of the first opening 111. In other words, the shape of the avoidance segment 143 is adapted to the shape of the edge of the first opening 111. For example, when the first opening 111 is circular, the avoidance segment 143 may be an arc shape; when the first opening 111 is rectangular, the avoidance segment 143 may be a straight line or a broken line. When the driver chip 130 is arranged symmetrically in the first direction X, the multiple fan-out traces 140 may also be arranged symmetrically in the first direction.

[0079] In some embodiments, the first opening 111 may be located inside the back fold 110, that is, the first opening 111 is surrounded by the back fold 110. Figure 19A The first opening 111 may also be a notch formed on one side of the two sides of the back fold 110 in the first direction X, that is, at least one side of the first opening 111 is not surrounded by the back fold 110, as shown in FIG. Figure 19BThat is, when the first opening 111 corresponds to the electronic component 20 , the first opening 111 can be provided at any position on the back folding portion 110 .

[0080] Please combine Figure 20 and Figure 21 , Figure 20 is a schematic diagram of the film structure of the display panel 100 when it is in a bent state. Figure 21 for Figure 20 FIG. 1 is a schematic diagram of the film structure of the display panel 100 when the display panel 100 is in a flat state.

[0081] The display panel 100 may include a panel body 101 and a film layer structure stacked on the panel body 101. The panel body 101 extends from the display portion 120 to the fixing portion 113 and the bending portion 114 of the back folding portion 110. The portion of the panel body 101 corresponding to the fixing portion 113 is the first panel body 1011. The portion of the panel body 101 corresponding to the bending portion 114 is the second panel body 1012. The portion of the panel body 101 corresponding to the display portion 120 is the third panel body 1013. The display function of the display panel 100 is realized by the third panel body 1013 of the panel body 101. That is, the fixing portion 113 may include the first panel body 1011, the bending portion 114 may include the second panel body 1012, and the display portion 120 may include the third panel body 1013.

[0082] In some embodiments, the display panel 100 may further include a back film (BF). For example, the fixing portion 113 may include a first back film 102, and the display portion 120 may include a second back film 103. The first back film 102 and the second back film 103 are disposed on the same side of the panel body 101 when flattened. Because the first back film 102 and the second back film 103 are disposed on the same side of the panel body 101 when flattened, after the bending portion 114 is bent, the first back film 102 and the second back film 103 are both disposed between the first panel body 1011 and the third panel body 1013. That is, after the bending portion 114 is bent, the first back film 102 and the second back film 103 are both located on the non-luminous side of the third panel body 1013.

[0083] The first back film 102 and the second back film 103 can be made of polyimide or PET, etc. The materials of the first back film 102 and the second back film 103 can be the same or different. The first back film 102 and the second back film 103 can support the display panel body 101.

[0084] The display portion 120 may further include a support film 104, which may be disposed on a side of the second backing film 103 away from the panel body 101. The support film 104 may be disposed in the same region as the second backing film 103. The support film 104 may be made of a rigid material, such as stainless steel (SUS). The support film 104 may also be made of super clean foam (SCF). The support film 104 may be used to smooth the surface of the panel body 101.

[0085] The display portion 120 may further include a polarizer (POL) 105, which may be disposed on the display side of the first panel body 1011. The polarizer 105 may be used to eliminate the polarization effect of light and enhance the display effect.

[0086] The display panel 100 may further include a protective film 107. The protective film 107 covers at least the second panel body 1012. The protective film 107 and the first backing film 102 are located on different sides of the panel body 101. That is, the protective film 107 and the first backing film 102 are located on different sides of the interconnected first panel body 1011, second panel body 1012, and third panel body 1013. The protective film 107 may cover the second panel body 1012 and extend a certain distance toward the first panel body 1011 and the third panel body 1013, respectively. In other words, the protective film 107 may cover the bent portion 114 of the back folding portion 110, as well as a portion of the fixed portion 113 of the back folding portion 110 and a portion of the display portion 120.

[0087] As mentioned above, the display panel 100 may further include a glass cover plate 108, which may be bonded to the display side of the first panel body 1011 via the optical adhesive 106. In the case where the display panel 100 includes a polarizer 105, the glass cover plate 108 may be bonded to the side of the polarizer 105 away from the first panel body 1011 via the optical adhesive 106.

[0088] Hereinafter, the present application will be further described based on possible film layer structures of the display panel 100 .

[0089] In some embodiments, as described above, the first opening 111 can be provided in the fixing portion 113. In this way, when the electronic component 20 is only provided below the fixing portion 113 of the back folding portion 110 and does not pass through the side frame 11 of the terminal device 10 or does not directly contact the side frame 11 of the terminal device 10, the position of the first opening 111 can be limited to the fixing portion 113 of the back folding portion 110, thereby ensuring that the electronic component 20 does not interfere with the back folding portion 110 while minimizing the area of ​​the first opening 111, thereby reducing the impact of the provision of the first opening 111 on the arrangement of fan-out wiring. For example, the electronic component 20 can be a camera 13 or a sensor.

[0090] Because the fixing portion 113 may include a first panel body 1011 and a first back film 102 stacked in layers, and after the bending portion 114 is bent, the first back film 102 is positioned on the side of the first panel body 1011 closest to the display portion 120, the first opening 111 provided in the fixing portion 113 may penetrate both the first panel body 1011 and the first back film 102. Specifically, the first panel body 1011 may be provided with a first sub-opening 1111, and the first back film 102 may be provided with a second sub-opening 1112. The first sub-opening 1111 and the second sub-opening 1112 are connected, thereby forming at least a portion of the first opening 111. In this case, the electronic component 20 may be positioned in the first opening 111 along the third direction Z. For example, the electronic component 20 may pass through both the first sub-opening 1111 and the second sub-opening 1112. The electronic component 20 may also pass through the first sub-opening 1111 and be partially located in the second sub-opening 1112. The electronic component 20 may not pass through the first sub-opening 1111, that is, only a portion of the electronic component 20 is disposed in the first sub-opening 1111. Of course, the electronic component 20 may not be disposed in the first sub-opening 1111. In this case, the first opening 111 can provide a mounting gap for the display portion 120 and the electronic component 20.

[0091] For example, the first sub-opening 1111 and the second sub-opening 1112 can have the same shape, and the size of the first sub-opening 1111 can be greater than or equal to the size of the second sub-opening 1112. In this way, the edge of the first sub-opening 1111 can be completely located in the area of ​​the first backing film 102 excluding the second sub-opening. As a result, the first backing film 102 provided with the second sub-opening 1112 can provide support for the edge of the first sub-opening 1111, reducing the impact on the strength of the first panel body 1011 caused by the first sub-opening 1111. Furthermore, the relatively large size of the first sub-opening 1111 can provide more space for the electronic component 20. It is understood that when the size of the first sub-opening 1111 is equal to that of the second sub-opening 1112, the edge of the first sub-opening 1111 can completely overlap with the edge of the second sub-opening 1112 along the third direction Z, and the first backing film 102 can also provide support for the first panel body 1011.

[0092] Exemplarily, the display portion 120 may include a second opening 121. After the bending portion 114 is bent, the second opening 121 at least partially overlaps with the first opening 111 in the thickness direction of the display portion 120 (coinciding with the third direction Z). That is, in addition to the first opening 111 provided in the back folding portion 110, the second opening 121 is also provided in the display portion 120, and after the back folding portion 110 of the display panel 100 is bent, the first opening 111 and the second opening 121 are connected. In this way, at least a portion of the electronic component 20 can be provided in the first opening 111 and the second opening 121, increasing the portion of the display panel 100 and the electronic component 20 that overlaps in the third direction Z, thereby further reducing the size occupied by the display panel 100 and the electronic component 20 in the third direction Z.

[0093] Similarly, because the display portion 120 may include a third panel body 1013 and a second back film 103, with the second back film 103 located on the non-display side of the third panel body 1013, the second opening 121 may also penetrate both the second back film 103 and the second panel 1012. For example, the third panel body 1013 is provided with a third sub-opening 1213, and the second back film is provided with a fourth sub-opening 1214. The third sub-opening 1213 and the fourth sub-opening 1214 are connected and form at least a portion of the second opening 121. The third sub-opening 1213 and the fourth sub-opening 1214 may have the same shape, and the size of the third sub-opening 1213 may be equal to the size of the fourth sub-opening 1214. In this way, the second back film 103 may also provide support for the third panel body 1013.

[0094] In addition, the display portion 120 may further include a support film 104, which is located on a side of the second backing film 103 away from the third panel body 1013. The support film 104 may be provided with a fifth sub-opening 1215. The third sub-opening 1213, the fourth sub-opening 1214, and the fifth sub-opening 1215 are connected and form at least a portion of the second opening 121. Therefore, the electronic component 20 may sequentially penetrate one or more layers of the support film 104, the second backing film 103, and the third panel body 1013 along the third direction Z. For example, the electronic component 20 may only penetrate the support film 104. Understandably, in this case, a portion of the electronic component 20 may extend into the second backing film 103 but not penetrate the second backing film 103. For another example, of course, the electronic component 20 may not penetrate the support film 104, but only a portion of the electronic component 20 may extend into the support film 104. The electronic component 20 may also not be disposed in the second opening 121. In this case, the second opening 121 can provide a mounting gap between the display portion 120 and the electronic component 20.

[0095] For example, when the display panel 100 includes both the first opening 111 and the second opening 121, the centerline L2 of the second opening 121 may coincide with the centerline L1 of the first opening 111. For example, when the cross-sectional shapes of the first opening 111 and the second opening 121 parallel to the XY plane are circular, the first opening 111 and the second opening 121 are both cylindrical. In this case, the coincidence of the centerline L1 of the first opening 111 and the centerline L2 of the second opening 121 means that the axis of the first opening 111 and the axis of the second opening 121 coincide. This prevents misalignment between the first opening 111 and the second opening 121, thereby facilitating the extension of the electronic component 20 from the first opening 111 into the second opening 121.

[0096] For example, after the back-folding portion 110 is bent, the boundary of the second opening 121 can be located inside the boundary of the first opening 111 along the thickness direction of the display portion 120 (i.e., the third direction Z). In other words, along the third direction Z, the first opening 111 does not block the second opening 121, and therefore, the first opening 111 does not affect the placement of a portion of the electronic component 20 in the second opening 121.

[0097] In some embodiments, see Figure 22 and Figure 23 and combined Figure 8A, the first opening 111 can extend from the fixed portion 113 to the bent portion 114. That is, after the bent portion 114 is bent, a portion of the first opening 111 can be located at both the fixed portion 113 and the bent portion 114 of the back folding portion 110, that is, at least a portion of the first opening 111 is disposed on the first panel body 1011 and the second panel body 1012. In this way, more space can be provided for electronic components disposed below the display portion 120 and disposed near the bent portion 114 on the side of the bent portion 114 away from the fixed portion 113. For example, even if an electronic component 20 such as the power interface 14 or the loudspeaker 15 passes through the side frame 11 of the terminal device 10 in the second direction Y or is directly mounted on the side frame 111, the first opening 111 can avoid the electronic component 20 and does not interfere with the electronic component 20.

[0098] In some embodiments, the first opening 111 may be provided only on the bent portion 114, that is, the first opening 111 may be provided only on the second panel body 1012. In this way, a certain amount of space can be provided for the electronic component provided below the display portion 120 and on a side of the bent portion 114 away from the fixing portion 113 and close to the bent portion 114. Thus, when the electronic component only overlaps with the bent portion 114 in the third direction Z, interference with the electronic component 20 can be avoided.

[0099] As previously mentioned, the first opening 111 may also be located in the fixing portion 113 and / or the bending portion 114. The fixing portion 113 includes a first panel body 1011 and a first back film 102 that are stacked. After the back folding portion 110 is bent, the first back film 102 is located on a side of the first panel body 1011 that is close to the display portion 120. The display portion 120 includes a third panel body 1013, and the bending portion 114 includes a second panel body 1012 that connects the first panel body 1011 and the third panel body 1013.

[0100] Based on this, the first panel body 1011 and / or the second panel body 1012 may be provided with a sixth sub-opening 1116. That is, the sixth sub-opening 1116 may be provided on the first panel body 1011 or the second panel body 1012, or may be provided on both the first panel body 1011 and the second panel body 1012. When the sixth sub-opening 1116 is provided on both the first panel body 1011 and the second panel body 1012, the sixth sub-opening 1116 extends from the first panel body 1011 to the second panel body 1012. Simultaneously, the first back film 102 may be provided with a seventh sub-opening 1117, and the sixth sub-opening 1116 and the seventh sub-opening 1117 are in communication. Thus, the sixth sub-opening 1116 and the seventh sub-opening 1117 form at least a portion of the first opening 111.

[0101] In addition, the display panel 100 may further include a protective film 107, which covers at least the second panel body 1012. The protective film 107 and the first back film 102 are located on different sides of the interconnected first panel body 1011 and second panel body 1012. The protective film 107 may be provided with a third opening 1113, which is connected to the first opening 111. The connection between the third opening 1113 and the first opening 111 can be achieved by the edge of the third opening 1113 completely coinciding with the edge of the sixth sub-opening 1116 of the first opening 111. It is understood that when the first back film 102 is far away from the bend 114 in the second direction Y or the first opening 111 is only provided on the bend 114, the first back film 102 may not be provided with the seventh sub-opening 1117.

[0102] It can be understood that the third opening 1113 provided on the protective film 107 can be a notch, which faces the fixing portion 113 ; the seventh sub-opening 1117 provided on the first back film 102 can also be a notch, which faces the bending portion 114 .

[0103] In some embodiments, see Figure 20 or Figure 22 The terminal device 10 may further include a bending spacer 150. After the back folding portion 110 is bent, the bending spacer 150 may be arranged between the display portion 120 and the fixing portion 113. The bending spacer 150 may include a fourth opening 154. The fourth opening 154 may be connected to the first opening 111, that is, the fourth opening 154 and the first opening 111 overlap in the third direction Z. In this way, the electronic component 20 may also be partially arranged in the fourth opening 154. It is understandable that when the bending spacer 150 is far away from the bending portion 114 in the second direction Y, the bending spacer 150 may not be provided with the fourth opening 154. It is understandable that the display portion 120 and the fixing portion 113 may both be fixedly combined with the bending spacer 150. In this way, after the bending portion 114 is bent, the fixing portion 113 is relatively fixed to the display portion 120, thereby improving the structural reliability of the terminal device 10. For example, the display portion 120 and the fixing portion 113 may be connected to both side surfaces of the spacer layer 150 in the third direction Z by an adhesive.

[0104] Furthermore, when the display panel 100 is provided with both the first opening 111 and the second opening 121, the fourth opening 154 can connect the first opening 111 and the second opening 121. Thus, in the terminal device 10, the second opening 121 can also prevent interference between the display portion 120 and the electronic component 20. The shape of the fourth opening 154 can be similar to that of the first opening 111 or the second opening 121, and the size of the fourth opening 154 can be between the size of the first opening 111 and the size of the second opening 121, that is, the size of the fourth opening 154 is greater than or equal to the size of the second opening 121 and less than or equal to the size of the first opening 111. Similarly, the centerline L3 of the fourth opening 154 can also coincide with the centerline L1 of the first opening 111 or the centerline L2 of the second opening 121.

[0105] When the display panel 100 includes only the first opening 111, the fourth opening 154 may be a notch, with the notch facing the bent portion 114. In this case, a portion of the electronic component 20 may be disposed in the fourth opening 154. When the electronic component 20 is not disposed in the fourth opening 154, the fourth opening 154 may provide a mounting gap for the electronic component 20.

[0106] It can be understood that the aforementioned openings can be formed through a cutting process when preparing the display panel 100. For example, the first opening 111 and / or the second opening 121 are formed in the display process, that is, the first opening 111 and / or the second opening 121 are formed when the substrate including multiple display panels is cut into multiple display panels 100.

[0107] The above are only specific embodiments of the present application, but the scope of protection of the application is not limited thereto. Any changes or substitutions that can be easily conceived by any person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
