[0026] DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0028] See also Figure 1 The spliced ​​display panel provided in the present application includes at least two sub-display panels 10, a splicing area is formed between adjacent sub-display panels 10, the spliced ​​display portion 20 at least covers the splicing area, and the electronic component 30 includes at least a photosensitive portion 301; wherein, along the light emitting direction of the spliced ​​display portion 20, a through hole 40 is provided through the spliced ​​display portion 20, and the photosensitive portion 301 is arranged in alignment with the through hole 40.

[0029] In this embodiment, the spliced ​​display part 20 is arranged to cover part of the spliced ​​area of ​​the adjacent sub-display panel 10, and a through hole 40 is set through the spliced ​​display part 20, so that the through hole 40 and the photosensitive part 301 of the electronic component 30 are aligned, thereby improving the integration and aesthetics of the spliced ​​display panel, and alleviating the technical problem of low integration of the existing spliced ​​display panel, which is prone to mechanical failure or dust entering the gap.

[0030] The technical solution of the present application is now described in conjunction with specific embodiments.

[0031] The embodiment of the present application only takes the sub-display panel 10 as a liquid crystal display panel, and the spliced ​​display unit 20 includes a light board 201, and the light board 201 is provided with an MLED light-emitting chip 2001 as an example for explanation. Other implementations of the sub-display panel 10 and the spliced ​​display unit 20 can be selected according to actual needs and also fall within the scope of protection of the present application; for example: the spliced ​​display unit 20 can also be an OLED display panel.

[0032] It should be noted that Figure 3 for Figure 1 A schematic cross-sectional view of a specific area 1 in FIG. Figure 4 for Figure 1 Another cross-sectional schematic diagram of a specific area 1 in FIG.

[0033] In one embodiment, see Figure 1 The sub-display panel 10 is a liquid crystal display panel, the spliced ​​display portion 20 includes at least two light bars, the light bars are arranged along the long side direction of the splicing area, and the through hole 40 is provided in any of the light bars.

[0034] The spliced ​​display portion 20 may include any one of two light bars, three light bars, four light bars, five light bars, and six light bars.

[0035] Wherein, a seam is provided between adjacent sub-display panels 10, and the seam is covered by the spliced ​​display portion 20, so that the seam is invisible; see Figure 1 , an example is given in which four light strips are arranged along the long side direction of the splicing area.

[0036] It can be understood that the light bar is also arranged along the extension direction of the edge of the sub-display panel 10 toward the splicing area, and the edge of the light bar is flush with the edge of the sub-display panel 10, or the light bar is set to cover the edge of the sub-display panel 10; so as to eliminate the splicing seams of the spliced ​​display panel.

[0037] It can be understood that the spliced ​​display portion 20 can also improve the screen-to-body ratio of the spliced ​​display panel, reduce the area occupied by the splicing seam, and even eliminate the splicing seam.

[0038] It should be noted that the through hole 40 may be arranged on the light board 201 above the splicing area, or may be arranged on the light board 201 below the splicing area. It can be selected according to actual needs and can be placed in the splicing area of ​​the splicing display panel according to the optimal shooting position.

[0039] In this embodiment, the light bar of the spliced ​​display portion 20 can emit light, and further, the spliced ​​display portion 20 can also display images, so as to eliminate the splicing seams generated by splicing adjacent sub-display panels 10 .

[0040] In an embodiment, a spliced ​​display portion 20 may also be provided at the frame of the spliced ​​display panel, and the spliced ​​display portion 20 at least partially covers the frame.

[0041] Among them, except for the frame at the splicing area, the frames on the other three sides of the sub-display panel 10 can also be eliminated by setting display elements similar to the splicing display part 20.

[0042] It is understandable that, since the spliced ​​display part 20 can eliminate the seams caused by splicing, similarly, using the spliced ​​display part 20 to cover the frame of the sub-display panel 10 reduces the width of the frame, which is conducive to achieving full-screen display.

[0043] In this embodiment, the width of the border can be reduced, thereby achieving full-screen display.

[0044] In one embodiment, see Figure 2 The electronic component 30 also includes a control unit for regulating the photosensitive unit 301 , and the control unit is electrically connected to the photosensitive unit 301 .

[0045] The functions of the control unit include but are not limited to receiving and processing the signal fed back by the light sensing unit 301 and driving at least one of the electronic components 30 .

[0046] The photosensitive surface of the photosensitive portion 301 of the electronic component 30 is disposed in the through hole 40 .

[0047] The control unit may be integrated into the sub-display panel 10 , or the control unit may be disposed below the sub-display panel 10 .

[0048] It can be understood that the control unit can be arranged in parallel with the TFT device of the sub-display panel 10 in the sub-display panel 10, which can improve the integration of the spliced ​​display panel and thus optimize the device structure of the spliced ​​display panel; further, the control unit can adopt some preset routing in the sub-display panel 10.

[0049] It can be understood that by arranging the control unit below the sub-display panel 10 instead of below the spliced ​​display unit 20, the space below the spliced ​​display unit 20 can be saved for setting the photosensitive unit 301 of the electronic element 30 and other components, which not only improves the utilization rate of the space on the side of the sub-display panel 10 close to the back panel, but also helps to further reduce the size of the spliced ​​display unit 20, thereby avoiding the poor display of the spliced ​​display unit 20 affecting the overall display effect of the spliced ​​display panel.

[0050] In one embodiment, see Figure 3The light bar includes a substrate 2002 and a plurality of MLED light emitting chips 2001 disposed on the substrate 2002 . The through hole 40 is disposed through the substrate 2002 , and the MLED light emitting chips 2001 on the light bar are disposed to avoid the through hole 40 .

[0051] The spacing between adjacent MLED light-emitting chips 2001 can be equal, so that the light emission in the area other than the through hole 40 on the light bar is more uniform.

[0052] In one embodiment, see Figure 3 The MLED light-emitting chips 2001 on both sides of the through hole 40 in at least one direction are symmetrically arranged.

[0053] Among them, see Figure 3 The first region 5 and the second region 6 are symmetrically arranged about the through hole 40 , and the MLED light-emitting chip 2001 in the first region 5 and the MLED light-emitting chip 2001 in the second region 6 are symmetrically arranged.

[0054] The MLED light emitting chips 2001 in the first area and the second area are arranged in an array.

[0055] It can be understood that the MLED light-emitting chips 2001 are symmetrically arranged, and the light emission of the spliced ​​display part 20 is more uniform, thereby improving the display uniformity.

[0056] In one embodiment, see Figure 4 The light bar provided with the through hole 40 includes a through hole area 2 and a transition area 3 arranged around the through hole area 2. In the transition area 3, the arrangement density of the MLED light-emitting chips 2001 gradually increases in a direction away from the through hole 40.

[0057] The light bar further includes a uniform light emitting area 4 , and the uniform light emitting area 4 is arranged around the transition area 3 .

[0058] The arrangement density of the MLED light-emitting chips 2001 in the uniform light-emitting area 4 is the same as the arrangement density of the MLED light-emitting chips 2001 in at least one circle of the transition area 3 close to the outermost side of the uniform light-emitting area 4 .

[0059] It can be understood that by setting a circle of transition zone 3 outside the through hole area 2, the density of the MLED light-emitting chip 2001 in the transition zone 3 is gradually increased toward the side away from the through hole area 2, thereby making the transition of the luminous intensity from the through hole area 2 to the uniform light-emitting area 4 smoother.

[0060] It should be noted that the size of the MLED light-emitting chip 2001 in the transition zone 3 can also be smaller than the size of the MLED light-emitting chip 2001 in the uniform light-emitting zone 4. By adjusting the size of the MLED light-emitting chip 2001 in the transition zone 3, the size of the MLED light-emitting chip 2001 gradually increases in the direction away from the through hole 40, so that the transition of the luminous intensity of the spliced ​​display part 20 from the through hole zone 2 to the uniform light-emitting zone 4 is smoother.

[0061] Furthermore, the transition zone 3 may also use MLED light-emitting chips 2001 with different luminous efficiencies, or use different numbers of MLED light-emitting chips 2001 in the transition zone 3, or a combination of the above methods, to achieve a smoother transition of the luminous intensity of the spliced ​​display part 20.

[0062] In this embodiment, a transition zone 3 is set between the through hole zone 2 and the uniform light-emitting zone 4, so that the setting density of the MLED light-emitting chip 2001 in the transition zone 3 gradually increases in the direction away from the through hole 40, thereby making the transition of the light intensity of the spliced ​​display part 20 smoother, reducing the light and dark boundaries, and enhancing the display effect.

[0063] In one embodiment, the electronic component 30 may be at least one of an imaging component, a temperature sensing component, a light sensing component, and a touch sensing component.

[0064] The light-sensing part 301 of the imaging element may be a camera.

[0065] In one embodiment, the through hole 40 is filled with a resin layer, and the resin layer includes a resin material.

[0066] The photosensitive portion 301 of the electronic component 30 may be disposed in the through hole 40 .

[0067] It is understandable that by filling the through hole 40 with resin material, the stress on the photosensitive portion 301 at the through hole 40 is reduced, so that the photosensitive portion 301 in the through hole 40 is not easily damaged or broken due to excessive stress.

[0068] In this embodiment, a resin layer is filled in the through hole 40 to protect the photosensitive portion 301 , thereby reducing stress or damage to the photosensitive portion 301 .

[0069] In one embodiment, the surface of the resin layer facing the light emitting direction is flush with the surface of the substrate 2002 facing the light emitting direction.

[0070] It can be understood that by filling the through hole 40 with a resin layer, the resin layer is flush with the upper surface of the substrate 2002 , thereby improving the flatness of the substrate 2002 .

[0071] In this embodiment, by filling the through hole 40 with a resin layer, not only the flatness of the substrate 2002 can be improved, but also the aesthetics of the entire device can be improved.

[0072] In one embodiment, the through hole 40 may be filled with a material having an anti-scratch function, or the through hole 40 may be filled with a material that blocks water and oxygen.

[0073] The anti-scratch material and the water and oxygen barrier material may be filled in the through hole 40 , or the anti-scratch material and the water and oxygen barrier material may be mixed in the resin layer.

[0074] In this embodiment, by filling or doping the through hole 40 with a material having a scratch-resistant function, the electronic component 30 is protected; by filling or doping the through hole 40 with a material that blocks water and oxygen, the electronic component 30 is prevented from failing.

[0075] In one embodiment, the opening of the through hole 40 is arranged in a direction perpendicular to the substrate 2002 .

[0076] It can be understood that by making the opening of the through hole 40 face perpendicular to the substrate 2002, the electronic component 30 located below the through hole 40 can receive more light, and when the electronic component 30 is an imaging element, the imaging clarity can be improved.

[0077] In some embodiments, the opening of the through hole 40 may also be arranged along a direction inclined with respect to the surface of the substrate 2002 on which the MLED light emitting chip 2001 is arranged.

[0078] In one embodiment, the shape of the photosensitive portion 301 is the same as that of the through hole 40 , and the photosensitive portion 301 is disposed in the through hole 40 .

[0079] It is understandable that the shape of the through hole 40 is the same as the shape of the photosensitive portion 301 of the electronic component 30 , so that the through hole 40 and the photosensitive portion 301 of the electronic component 30 are contour-matched, which is conducive to embedding the photosensitive portion 301 into the through hole 40 .

[0080] It can be understood that the light receiving surface of the light sensing portion 301 can be tilted relative to the hole wall of the through hole 40, which is beneficial to increase the area of ​​the light receiving surface.

[0081] In one embodiment, the through hole 40 can be formed by digging multiple times.

[0082] The through holes 40 may be arranged in a stepped shape.

[0083] The photosensitive portion 301 may be disposed in any of the holes.

[0084] In one embodiment, the spliced ​​display panel further includes a driving component 50 disposed on at least one side of the spliced ​​display panel, and the driving component 50 includes a driving end 501 and a connecting end 502 connecting the driving circuit board and the sub-display panel 10 .

[0085] In one embodiment, the through hole area is further provided with an auxiliary light emitting unit for displaying a picture, and the transition area and the uniform display area are provided with a main light emitting unit.

[0086] Wherein, the auxiliary light-emitting unit may be arranged above the resin layer of the through hole.

[0087] It can be understood that by disposing an auxiliary light-emitting unit in or above the through hole, the light transmittance of the through hole is taken into consideration while preventing the through hole from being always dark and affecting the display effect, thereby optimizing the display effect of the spliced ​​display part.

[0088] It should be noted that the auxiliary light-emitting unit may be a pixel unit or a micro-light-emitting LED; similarly, the main light-emitting unit may be a pixel unit or a micro-light-emitting LED, and the spliced ​​display part may be selected according to actual needs.

[0089] In one embodiment, the arrangement density of the auxiliary light-emitting units at the through hole is smaller than the arrangement density of the main light-emitting units in the transition area and the uniform display area.

[0090] In this embodiment, the light transmission effect at the through hole is enhanced by adjusting the arrangement density of the auxiliary light-emitting units at the through hole.

[0091] In one embodiment, the light-shielding metal wiring and the TFT device structure connected to the auxiliary light-emitting unit are staggered with the through hole in the thickness direction.

[0092] Wherein, only transparent wiring is arranged at the through hole.

[0093] In this embodiment, by setting the shading metal routing and TFT device structure outside the through hole and staggered with the through hole, the light transmittance of the through hole is avoided, the light transmittance of the through hole is further improved, which is beneficial for the photosensitive surface of the electronic component to receive more light.

[0094] The present application integrates electronic components into the spliced ​​display part. Compared with the prior art in which electronic components are separately arranged on the spliced ​​display panel, the present application improves the integration and aesthetics of the spliced ​​display panel. The photosensitive part of the electronic component is arranged in alignment with the through hole, and the electronic component does not need to be arranged on the spliced ​​display panel by telescopic means. The occurrence of mechanical failures can also be reduced, and dust can be prevented from entering the spliced ​​display panel through the mechanical connectors.

[0095] The present application also proposes a display module and a terminal device, both of which include the above-mentioned spliced ​​display panel, which will not be repeated here; wherein, the display module also includes at least one of a back panel, a cover panel, an optical film, and a polarizer, and the terminal device includes but is not limited to a mobile phone, a laptop computer, and a tablet computer.

[0096] The spliced ​​display panel provided in the embodiment of the present application includes at least two sub-display panels, a splicing area is formed between adjacent sub-display panels, the spliced ​​display part at least covers a portion of the splicing area, and the electronic component includes at least a photosensitive part, wherein a through hole is provided through the spliced ​​display part along the light emitting direction of the spliced ​​display part, and the photosensitive part is aligned with the through hole; the spliced ​​display part covers the splicing area of ​​adjacent sub-display panels, and then a through hole is provided through the spliced ​​display part, so that the through hole and the photosensitive part of the electronic component are aligned, thereby improving the integration and aesthetics of the spliced ​​display panel, and alleviating the technical problem that the existing spliced ​​display panel has low integration, which leads to easy mechanical failure or dust entering the gap.

[0097] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0098] The spliced ​​display panel provided in the embodiment of the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
