[0003] Current curved display devices include those with a flat center and partially or completely curved edges. However, during installation, the electronic circuit board of the display device can easily come into contact with the cover plate, causing the adhesive used to mount the electronic circuit board to adhere to the cover plate surface, affecting the subsequent display quality of the display device. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the related art, it is desired to provide a display device and an electronic device that can solve the problem that the electronic circuit board of the display device is easily connected to the cover plate during the installation process, causing the colloid used to install the electronic circuit board to stick to the surface of the cover plate, affecting the subsequent display effect of the display device, thereby ensuring the display integrity of the display screen and greatly improving the display effect.

[0006] The display panel is configured to be attached to one end of the electronic circuit board in the second area, and the cover plate is attached to the other end of the electronic circuit board in the second area away from the display panel.

[0021] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The following will describe the application scenarios of this application in detail with reference to the accompanying drawings and in combination with the embodiments.

[0023] With the development of electronic devices, screen displays are becoming more and more diverse, and curved screens are one of them.

[0024] Current curved display panels include one in which the center of the display panel is flat and some or all of the edges of the display panel are curved. Figure 1 As shown, Figure 1 A side view showing the positional relationship between an electronic circuit board and a display device in a cutaway side view of a display device is shown.

[0025] exist Figure 1 In the conventional display device, the partial diagram can be used to indicate any part of the conventional display device. For example, assuming the conventional display device is a mobile phone or tablet computer, the partial diagram can be used to indicate the bottom area of ​​the mobile phone or tablet computer near the microphone, or the top area near the earpiece, or the other two side areas of the mobile phone or tablet computer.

[0026] It is understandable that, generally, for electronic devices including display devices, in order to ensure a high degree of fit of the electronic circuit board in the electronic device, the electronic circuit board is installed by bending and fitting from the back of the display device to the front of the display device. Figure 1 As shown, Figure 1 The upper area of ​​the display device is the rear non-display area, and the lower area is the front display area. The electronic circuit board 11 is bonded to the rear non-display area of ​​the display device 13 via a colloid 12 (e.g., MCL colloid). It then bends toward the front display area of ​​the display device 13 in the direction indicated by the arrow, and finally bonds to the front display area of ​​the display device 13, completing the installation of the electronic circuit board.

[0027] However, in the above process, since the edge of the cover glass of the display device 13 is a raised structure, the colloid of the electronic circuit board 11 is easily adhered to the cover glass of the display device 13 during the bending process of the electronic circuit board 11, thereby affecting the display effect of the subsequent curved display panel.

[0028] Based on this, the present application proposes a display device and an electronic device that can solve the problem that during the process of bonding the colloid electronic circuit board to the front edge of the curved display panel, the colloid easily sticks to the surface of the display screen, thereby affecting the subsequent display effect of the curved display panel, thereby ensuring the display integrity of the display screen and greatly improving the display effect.

[0029] Figures 2 to 7 An embodiment of the present application provides a display device, which includes a stacked display panel and a cover plate. The display device includes a first area and a second area, and the second area of ​​the display device is a curved area.

[0030] Exemplarily, the cover plate may be a glass cover plate (Cover Glass), and the display panel includes a multi-layer panel structure, for example, including a polarizer (POL), an optical adhesive (OCA), and the like.

[0031] Exemplarily, the first area is a planar area in the display device.

[0032] It is understandable that, for a display device, the display device includes a curved surface area and a flat surface area, the middle area of ​​the display device is a flat surface area, and the edge area of ​​the display device may have a curved surface area. The curved surface area may be located in the entire edge area of ​​the display device, or in part of the edge area. For example, in the case where the display device is a display device of a quadrilateral electronic device, the curved surface area may be located in the edge area of ​​each side of the quadrilateral electronic device, that is, the display device of the quadrilateral electronic device is a four-curved module, or it may be located in the edge area of ​​part of the side of the quadrilateral electronic device.

[0033] It can be understood that the display panel of the above display device has curved surfaces on both the side close to the cover plate and the side away from the cover plate in the second region.

[0034] Furthermore, the above-mentioned cover plate will be made into a component with curved edges and horizontal inner sides during the manufacturing process, and the display panel can be composed of multiple layers of optical film layers. The display panel is a flexible structure. After the display panel is attached to the cover plate and set, the side of the display panel close to the cover plate and the side away from the cover plate are both adapted to the cover plate to form a curved surface.

[0035] In an embodiment of the present application, the display panel is configured to be bonded to one end of the electronic circuit board in the second area, and the cover is bonded to the other end of the electronic circuit board in the second area away from the display panel.

[0036] In one example, the display panel and the electronic circuit board may be bonded together by a bonding material. For details, please refer to the subsequent description and will not be elaborated here.

[0037] Furthermore, the above-mentioned adhesive can be MCL glue.

[0038] Exemplarily, the electronic circuit board is an electronic circuit board of an electronic device to which the display device belongs.

[0039] like Figure 2 and Figure 3 As shown, Figure 2 It can be seen that a display panel 15 is provided on the back of the terminal to which the display device belongs, and an electronic circuit board 11 is provided in the display panel 15. A recess 31 is provided on the side of the electronic circuit board 11 close to the cover plate, which will be Figure 2 The marked arc dotted line is bent in the direction to the front of the terminal, that is, the front of the display device cover. Figure 3 for Figure 2 In the side view of the section along the AA direction, it includes an electronic circuit board 11 and a glass cover plate 14 (also known as the above-mentioned cover plate), wherein: Figure 3The area of ​​the glass cover corresponding to the dotted line frame 21 is the first area, and the area of ​​the glass cover 14 corresponding to the dotted line frame 22 is the second area. In the second area where the dotted line frame 22 is located, one end of the electronic circuit board 11 (the dotted line frame 11a) is connected to the display panel 15 ( Figure 2 The other end of the electronic circuit board 11 (the dotted frame 11b) is attached to the side of the glass cover 14 away from the display panel, and the electronic circuit board is curved.

[0040] In an embodiment of the present application, the cover plate is provided with a clearance groove at a first edge opposite to the electronic circuit board in the second region, and the depth direction of the clearance groove is consistent with the direction in which the electronic circuit board bends from the display panel to the cover plate.

[0041] Exemplarily, a clearance groove is provided at a position corresponding to the electronic circuit board on the first edge of the cover plate, that is, the position of the clearance groove corresponds to the position of the electronic circuit board.

[0042] Exemplarily, the depth direction of the above-mentioned give way groove refers to the longitudinal depth direction of the give way groove.

[0043] In an example, the depth direction may be an extension direction of the first edge from the outer side of the cover plate edge to the inner side of the cover plate edge.

[0044] It can be understood that in the embodiment of the present application, the reason for providing the above-mentioned clearance groove is that the electronic circuit board will be adhered to the display panel through a sticky substance, and the sticky substance is located on the side of the electronic circuit board close to the cover plate. Therefore, in the subsequent process of bending the electronic circuit board toward the cover plate, there is a possibility that the sticky substance will stick to the cover plate. In order to ensure that the sticky substance does not stick to the cover plate, the clearance groove will be provided to increase the distance between the circuit panel and the cover plate after bending, so that the side of the electronic circuit board close to the cover plate will not contact the cover plate, thereby ensuring the later display effect of the cover plate.

[0045] In the method provided in an embodiment of the present application, a display device includes a stacked display panel and a cover plate, wherein the display device includes a first region and a second region with a curved structure; the display panel is configured to be bonded to one end of an electronic circuit board in the second region, and the cover plate is bonded to the other end of the electronic circuit board in a second region away from the display panel; the cover plate has a clearance groove formed on a first edge of the second region opposite the electronic circuit board, wherein the depth of the clearance groove is consistent with the direction in which the electronic circuit board bends from the display panel to the cover plate. Thus, by providing the clearance groove on the first edge of the cover plate opposite the electronic circuit board, a certain distance is created between the electronic circuit board bonded to the display panel and the cover plate. This ensures that after the electronic circuit board is bent to one side of the cover plate, the bent electronic circuit board on the side bonded to the display panel can maintain a certain distance from the cover plate. This further ensures that the adhesive on the electronic circuit board used for bonding to the display panel will not subsequently contact the surface of the cover plate, thereby ensuring the subsequent display integrity of the display device and significantly improving the display effect.

[0046] Optionally, in an embodiment of the present application, the above-mentioned clearance groove passes through the first surface and the second surface of the above-mentioned cover plate, and the length of the above-mentioned clearance groove along the above-mentioned first edge is less than the length of the above-mentioned first edge.

[0047] Exemplarily, the first surface is a surface of the cover plate close to the electronic circuit board, and the second surface is a surface of the cover plate away from the electronic circuit board.

[0048] It can be understood that in order to ensure that there is a certain distance between the above-mentioned clearance groove and the electronic circuit board, and the electronic circuit board will not contact the cover plate after being bent, the clearance groove needs to be opened from one side of the cover plate to the other side at the edge of the above-mentioned cover plate, that is, the clearance groove passes through the first side and the second side of the cover plate, so that the cover plate completely gives way to the area where the sticky substance is attached to the electronic circuit board, ensuring that the sticky substance will not stick to the cover plate.

[0049] like Figures 2 to 4 As shown, in Figure 2 and Figure 4 is a three-dimensional perspective view of the above-mentioned clearance groove, that is, a side view of the display device cut from the clearance groove, Figure 4 This is a three-dimensional schematic diagram of a display device, for example, a mobile phone. In this electronic device, the clearance groove 31 extends from the side of the glass cover 14 closest to the electronic circuit board 11 (i.e., the first side) to the side of the glass cover 14 farther from the electronic circuit board 11 (i.e., the second side).

[0050] Optionally, in an embodiment of the present application, the size parameters of the above-mentioned clearance groove match at least one of the size parameters of the above-mentioned electronic circuit board and the distance parameters of the above-mentioned electronic circuit board.

[0051] Exemplarily, the distance parameter is used to characterize the interval between the electronic circuit board and the bottom of the recess.

[0052] It can be understood from the above content that the above-mentioned clearance groove is a groove body dug through the first and second surfaces of the cover plate, and its function is to ensure that during the bending process of the electronic circuit board, the area where the sticky substance is attached to the electronic circuit board will not contact the cover plate.

[0053] Exemplarily, the matching of the dimensional parameters of the above-mentioned clearance groove and the dimensional parameters of the above-mentioned electronic circuit board means that the dimensional parameters of the clearance groove need to enable the electronic circuit board to be suspended and embedded therein without contacting the groove surface of the clearance groove.

[0054] Furthermore, the length of the above-mentioned clearance groove is the sum of the length of the above-mentioned electronic circuit board along the above-mentioned first edge and the fitting tolerance between the above-mentioned electronic circuit board and the above-mentioned clearance groove.

[0055] It is understandable that when the electronic circuit board is suspended and embedded in the clearance groove, the electronic circuit board is close to the bottom side of the cover plate and needs to keep a distance from the clearance groove, and the side of the electronic circuit board also needs to keep a distance from the clearance groove.

[0056] Exemplarily, the above-mentioned fitting tolerance refers to the distance between the two sides of the electronic circuit board and the clearance groove.

[0057] In one example, the spacing distances between the two sides of the electronic circuit board and the clearance groove are consistent.

[0058] Furthermore, since it is impossible to ensure that the length of each electronic circuit board is completely consistent during the production process, in order to ensure that the two sides and the bottom of the electronic circuit board will not touch, a production tolerance can be added on the basis of the sum of the fitting tolerance corresponding to the length of the above-mentioned groove and the length of the electronic circuit board along the first edge.

[0059] like Figure 5 As shown, Figure 5 : is a cross-sectional view of the other side of the electronic circuit board 11 and the glass cover 14. The length of the clearance groove 31 is equal to the length of the electronic circuit board 11 along the first edge of the glass cover 14 plus the fitting tolerance 41 on both sides and the production tolerance.

[0060] Exemplarily, the matching of the size parameters of the above-mentioned giveway groove and the distance parameters of the above-mentioned electronic circuit board means: as described above, the groove surface of the giveway groove needs to ensure that it is in a non-contact state with the electronic circuit board, then a certain distance needs to be maintained between the electronic circuit board and the groove surface of the giveway groove parallel to the electronic circuit board. This distance is the distance parameter, and this distance parameter determines the depth of the giveway groove.

[0061] Furthermore, the depth of the above-mentioned clearance groove is greater than the distance parameter of the above-mentioned electronic circuit board.

[0062] Exemplarily, the above distance parameter is as described above, and is used to characterize the distance between the electronic circuit board and the bottom of the clearance groove.

[0063] It is understandable that in order to ensure that the electronic circuit board can be suspended and embedded in the clearance groove, the depth of the clearance groove must be greater than the distance between the electronic circuit board and the bottom groove surface of the clearance groove.

[0064] like Figure 5 As shown, in Figure 5 In the embodiment, the depth of the above-mentioned clearance groove 31 is greater than the distance between the clearance groove 31 and the side of the electronic circuit board 11 close to the glass cover 14.

[0065] Optionally, in an embodiment of the present application, the display device further comprises a sticker, which is arranged on a side of the electronic circuit board close to the cover plate and corresponds to the position of the above-mentioned give way groove. When the electronic circuit board is bent, there is a gap between the sticker and the side of the give way groove close to the above-mentioned give way groove.

[0066] It is understandable that, as described above, the adhesive is used to attach the electronic circuit board to the display device and is a viscous substance. In one example, the viscous substance can be MCL glue.

[0067] like Figure 3 As shown, Figure 3 The side of the electronic circuit board 11 close to the glass cover plate 14 is adhered with MCL glue 12, and the MCL glue 12 has a certain thickness. The electronic circuit board will subsequently be bent along the direction of the arrow to the side of the glass cover plate 14 away from the electronic circuit board 11. Since a clearance groove 31 corresponding to the position of the MCL glue 12 is provided, the electronic circuit board 11 can be bent and adhered to the side of the glass cover plate 14 away from the display panel 15 without the MCL glue 12 contacting the glass cover plate 14, that is, there is a certain distance between the MCL glue 12 and the glass cover plate 14.

[0068] Optionally, in an embodiment of the present application, the display panel includes a plurality of sub-panels stacked together.

[0069] Exemplarily, the bottom of the recess is aligned with the edge height of the first sub-panel among the plurality of sub-panels.

[0070] It is understandable that the display panel may include a plurality of sub-panels, and the sub-panels may include a polarizer layer, an optical adhesive layer, and the like.

[0071] Exemplarily, the first sub-panel may be any layer in the display panel, or may be a specific layer, such as a polarizer layer.

[0072] Exemplarily, the edge of the first sub-panel is an edge close to a side of the electronic circuit board.

[0073] like Figure 3 As shown, in Figure 3 In the embodiment, the display panel 15 may include a polarizer layer and an optical adhesive layer. As can be seen, the bottom of the recess is flush with the upper edge of the polarizer layer 16 on the side close to the electronic circuit board 11 (the red dotted line corresponds to the flush position).

[0074] Furthermore, in order not to affect the display effect of the cover plate, the outermost point of the front projection of the cover plate can be used as the first alignment line with the bottom of the clearance groove.

[0075] Furthermore, a second alignment line corresponding to the deviation distance and parallel to the first alignment line is extended in a direction opposite to the extending direction of the depth of the give way groove corresponding to the first alignment line, and is the bottom position of the give way groove.

[0076] like Figure 5 As shown, the outermost point of the cover plate outer contour is used as the first alignment line 51, and the second alignment line 52 is deviated 0.1 mm (i.e., the above-mentioned deviation distance) upward from the horizontal line. On the one hand, it prevents the glass cover plate 14 from being overcut during the secondary CNC machining after hot bending, and on the other hand, it also ensures the strength of this part.

[0077] Optionally, in an embodiment of the present application, the angle between the side surface of the above-mentioned give way groove along the depth direction and the bottom of the above-mentioned give way groove is not equal to ninety degrees, and the opening area of ​​the above-mentioned give way groove is larger than the bottom area of ​​the above-mentioned give way groove.

[0078] Exemplarily, two sides in the horizontal direction parallel to the display panel are non-vertical edges.

[0079] It is understandable that in order to ensure that the electronic circuit board does not contact the cover plate during the entire process, the shape of the clearance groove is set to be trapezoidal, and the width of the bottom of the clearance groove is smaller than the width of the slot, thereby ensuring sufficient clearance.

[0080] Exemplarily, the angle between the bottom of the above-mentioned clearance groove and the side surface in the depth direction of the clearance groove is greater than or equal to 135 degrees and less than 180 degrees.

[0081] like Figure 6 As shown, Figure 6 In the embodiment, the included angles A1 and A2 between the bottom of the clearance groove and the side surface in the depth direction of the clearance groove are both 135°.

[0082] Optionally, in an embodiment of the present application, a surface of the above-mentioned clearance groove close to the above-mentioned electronic circuit board is coated with a lubricating material to prevent the above-mentioned first sub-panel from contacting with the above-mentioned electronic circuit board.

[0083] It is understandable that, in addition to the above-mentioned recess, in order to further ensure that the electronic circuit board's laminate is not in direct contact with the cover plate, lubricating material may be provided to ensure that the electronic circuit board's laminate is completely isolated from the cover plate.

[0084] Exemplarily, the lubricating material may be silicone oil.

[0085] Optionally, in an embodiment of the present application, a release film is provided on the surface of the above-mentioned clearance groove close to the electronic circuit board, and a lubricating material is coated on the above-mentioned release film to prevent the above-mentioned first sub-panel from contacting the electronic circuit board.

[0086] For example, the release film may include a PET substrate and PSA.

[0087] It is understood that a lubricating material can be applied to the non-adhesive surface of the release film substrate PET, so that when the electronic circuit board is bent from one side close to the cover plate to the other side of the cover plate (such as Figure 2 After confirming that the electronic circuit board will not come into contact with the clearance groove, you can tear off the release film.

[0088] like Figure 7 As shown, Figure 7 In the embodiment, a release film is provided at the bottom of the recess, comprising a PET 17 substrate and a PSA 18 , and silicone oil 19 (ie, the above-mentioned lubricating material) is provided on the release film.

[0089] The embodiment of the present application further discloses an electronic device, which includes the above-mentioned display device and a microphone, wherein the recess of the above-mentioned display device is arranged near the edge of the microphone;

[0092] The cover plate is provided with a clearance groove at a first edge opposite to the electronic circuit board in the second region, and a depth direction of the clearance groove is consistent with a bending direction of the electronic circuit board from the display panel to the cover plate.

[0093] In one embodiment, the clearance groove passes through the first and second surfaces of the cover plate, and the length of the clearance groove along the first edge is less than the length of the first edge; the first surface is the side of the cover plate close to the electronic circuit board, and the second surface is the side of the cover plate away from the electronic circuit board.

[0094] In one embodiment, the length of the clearance groove is the sum of the length of the electronic circuit board along the first edge and the fitting tolerance between the electronic circuit board and the clearance groove, and the fitting tolerance is the distance between the two sides of the electronic circuit board in the horizontal direction and the clearance groove.

[0095] In one embodiment, the depth of the clearance groove is greater than a distance parameter of the electronic circuit board, and the distance parameter is used to represent the interval between the electronic circuit board and the bottom of the clearance groove.

[0096] In one embodiment, the display device further includes a sticker, which is arranged on a side of the electronic circuit board close to the cover plate and corresponds to the position of the give way groove.

[0097] In one embodiment, the display panel includes a plurality of stacked sub-panels, and the bottom of the recess is aligned with the edge of a first sub-panel among the plurality of sub-panels.
