Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device and electronic device. Background Technology

[0002] Currently, ultra-narrow bezel video walls use a frameless design to reduce the width of the seams. However, because the distance from the display area to the edge of an ultra-narrow bezel video wall is very narrow, it is not possible to effectively use back adhesive for fixation. Therefore, the adhesive needs to be inserted deep into the display area. At the same time, to prevent the edge shadow problem of the video wall, the adhesive needs to be placed below the optical adjustment control so that light can shine on the edge covered by the adhesive, and the display panel, optical film, and diffuser plate are then bonded and fixed together.

[0003] However, this also results in extremely poor maintainability of splicing screens. If an abnormality is found in the optical film during assembly or use, or if it is necessary to replace the optical film to achieve different optical performance capabilities, the entire support plate and optical film can only be scrapped, or even high-priced materials such as the display panel can be scrapped. Summary of the Invention

[0004] In view of this, this application provides a display device and an electronic device, which enables the display device to replace the optical film without damaging the diffuser plate and the display panel, thereby effectively saving the maintenance cost of the display device.

[0005] In a first aspect, this application provides a display device, the display device comprising:

[0006] Display panel, the display panel having a display surface;

[0007] A diffuser plate is disposed on the side of the display panel opposite to the display surface. The diffuser plate has a first surface facing the display panel and a second surface bent and connected to the first surface. The diffuser plate also has a receiving cavity, and the receiving cavity has an opening on the second surface.

[0008] An optical film is detachably connected to the diffuser plate. The optical film is at least partially housed within the receiving cavity of the diffuser plate and is stacked with the display panel.

[0009] The display device further includes a back plate, which is disposed on the side of the diffuser plate away from the display panel and supports the diffuser plate. The optical film includes a connected body portion and a folded ear portion. The body portion is housed in the receiving cavity of the diffuser plate. The folded ear portion is disposed adjacent to an opening on the second surface, and one end of the folded ear portion is connected to the body portion, while the other end of the folded ear portion is connected to the back plate.

[0010] The display device further includes a circuit board and a chip-on-film. The circuit board is disposed on the side of the back plate away from the display panel. One end of the chip-on-film is electrically connected to the display panel, and the other end of the chip-on-film is electrically connected to the circuit board.

[0011] The display device further includes an encapsulation part disposed at one end of the display panel away from the flip-chip film and encapsulating the display panel. The encapsulation part has a thickness range D1, wherein D1 ≤ 0.3 mm.

[0012] The flip-chip film is disposed on one side adjacent to the second surface of the diffusion plate, and the diffusion plate also has a third surface disposed opposite to the second surface. The sidewall of the diffusion plate forming the receiving cavity is spaced apart from the third surface.

[0013] The flip-chip film is disposed on the side opposite to the second surface of the diffuser plate, and the diffuser plate also has a third surface disposed opposite to the second surface. The sidewall of the diffuser plate forming the receiving cavity is spaced apart from the third surface.

[0014] The backplate includes a main body and a support portion that are bent and connected. The support portion is disposed on the side of the main body adjacent to the diffuser plate, and the diffuser plate has a sloped area on the side adjacent to the flip-chip film. The support portion is disposed at least partially adjacent to the sloped area and supports the diffuser plate.

[0015] The optical film has a thickness range D2, wherein 0.2mm≤D2≤2mm.

[0016] The display device further includes a first adhesive layer sandwiched between the diffuser plate and the back plate. The first adhesive layer is made of a light-transmitting material and has a thickness range D3, wherein 0.05mm≤D3≤0.7mm.

[0017] The display device further includes a second adhesive layer sandwiched between the display panel and the diffuser plate. The second adhesive layer is made of a light-transmitting material, and its projection onto the diffuser plate covers the first surface.

[0018] Secondly, this application provides an electronic device comprising at least two interconnected display devices, with a seam between adjacent interconnected display devices, and each display device having a first non-display area, a display area, and a second non-display area arranged sequentially, the width of the seam being equal to the width of the first non-display area plus the width of the second non-display area.

When the optical film 13 needs to be replaced, the optical film 13 can be directly removed from the receiving cavity 123 of the diffuser plate 12. Compared with the traditional method of bonding the optical film 13 to the surface of the diffuser plate 12, the display device 10 can replace the optical film 13 without damaging the diffuser plate 12 and the display panel 11, thereby effectively saving the maintenance cost of the display device 10.

[0070] Specifically, the encapsulation layer is disposed on the end side of the display panel 11, which can improve the end strength of the display panel 11, prevent moisture intrusion from the side of the display panel 11 and thus prevent the display panel 11 from separating, thereby effectively extending the service life of the display device 10 and ensuring the safety and reliability of the display device 10. Furthermore, the thickness range D1 of the encapsulation portion 17 satisfies D1≤0.3mm, which also allows for a thinner and lighter design of the display panel 11, improving the user experience.

[0071] Optionally, the display device 10 may or may not have a front bezel. In the schematic diagram of this embodiment, the display device 10 is shown without a front bezel, thus giving it a narrow bezel design.

Figure 2The flip-chip film 16 is disposed on one side adjacent to the second surface 122 of the diffuser plate 12, and the diffuser plate 12 also has a third surface 124 disposed opposite to the second surface 122. The sidewall of the diffuser plate 12 forming the receiving cavity 123 is spaced apart from the third surface 124.

[0073] Optionally, in one embodiment of this application, the second surface 122 is the surface of the diffuser plate 12 adjacent to the flip-chip film 16.

[0074] Optionally, the display device 10 has a chamfered edge and a non-chamfered edge. The non-chamfered edge can be understood as the side of the display device 10 where the flip-chip film 16 and the circuit board 15 are disposed, and the chamfered edge can be understood as the side of the display device 10 that is disposed opposite to the non-chamfered edge.

[0075] Specifically, in this embodiment, the diffusion plate 12 has the receiving cavity 123 on the bonding side of the bonding film 16, and the opening 1231 of the receiving cavity 123 is disposed adjacent to the bonding film 16 and the circuit board 15. In other words, the diffusion plate 12 has the receiving cavity 123 on the non-clipped edge of the display device 10, so that during the assembly process of the display device 10, the optical film 13 can be assembled on the same side as the circuit board 15 and the bonding film 16, thereby facilitating the rapid assembly of the display device 10 and improving the assembly efficiency of the display device 10.

[0076] Optionally, the diffuser plate 12 further has a third surface 124 disposed opposite to the second surface 122, that is, the third surface 124 is the surface of the diffuser plate 12 adjacent to the non-bonding side. The third surface 124 may also be disposed opposite to the second surface 122.

[0077] Optionally, the sidewall of the diffuser plate 12 forming the receiving cavity 123 is spaced apart from the third surface 124, that is, the receiving cavity 123 has an opening 1231 only on one side of the diffuser plate 12, and does not penetrate the diffuser plate 12 on the other side. This allows the sidewall of the diffuser plate 12 forming the receiving cavity 123 to limit the optical film 13, which facilitates the replacement of the optical film 13 and ensures the positional stability of the optical film 13 in the display device 10, thereby ensuring that the display device 10 has stable and excellent optical quality.

[0078] Please see Figure 3 , Figure 3This is a cross-sectional structural diagram of the display device according to Embodiment 1 of this application along line AA. The flip-chip film 16 is disposed on the side opposite to the second surface 122 of the diffuser plate 12, and the diffuser plate 12 also has a third surface 124 disposed opposite to the second surface 122. The sidewall of the diffuser plate 12 forming the receiving cavity 123 is spaced apart from the third surface 124.

[0079] Alternatively, in another embodiment of this application, the second surface 122 is the surface of the diffuser plate 12 facing away from the flip-chip film 16.

[0080] Specifically, in this embodiment, the diffuser plate 12 has the receiving cavity 123 on the side where the flip-chip film 16 is not attached (non-bonding side), and the opening 1231 of the receiving cavity 123 is disposed away from the flip-chip film 16 and the circuit board 15. In other words, the diffuser plate 12 has the receiving cavity 123 on the chamfered edge of the display device 10, so that after the diffuser plate 12 houses the optical film 13, the optical film 13 can be disposed adjacent to the chamfered edge of the display device 10, so that more light can be refracted or diffused by the optical film 13 and incident on the chamfered edge of the display panel 11, thereby better eliminating the shadow problem of the narrow bezel of the chamfered edge of the display device 10 and improving the display effect of the display device 10.

[0081] Optionally, the diffuser plate 12 further has a third surface 124 disposed opposite to the second surface 122, that is, the third surface 124 is the surface of the diffuser plate 12 adjacent to the bonding side. The third surface 124 may also be disposed opposite to the second surface 122.

[0082] Optionally, the sidewall of the diffuser plate 12 forming the receiving cavity 123 is spaced apart from the third surface 124, that is, the receiving cavity 123 has an opening 1231 only on one side of the diffuser plate 12, and does not penetrate the diffuser plate 12 on the other side. This allows the sidewall of the diffuser plate 12 forming the receiving cavity 123 to limit the optical film 13, which facilitates the replacement of the optical film 13 and ensures the positional stability of the optical film 13 in the display device 10, thereby ensuring that the display device 10 has stable and excellent optical quality.

[0083] Please see Figure 4 , Figure 4This is a cross-sectional structural diagram of the display device according to Embodiment 2 of this application along line AA. The back plate 14 includes a main body 141 and a support 142 that are bent and connected together.

The support 142 is disposed at least partially adjacent to the sloped area 125 and supports the diffuser plate 12.

[0084] Optionally, the main body 141 and the support 142 may be integrally formed. Understandably, the main body 141 and the support 142 may also be connected by means of bonding, soldering, or fasteners, etc. This application does not limit this.

[0085] Optionally, the bending angle between the main body 141 and the support 142 can be 90°, 100°, 110°, 120°, 130°, or other values.

[0086] Optionally, the support portion 142 is disposed on the side of the main body portion 141 adjacent to the diffuser plate 12, and the support portion 142 can be disposed in contact with the diffuser plate 12 to support the diffuser plate 12.

[0087] Optionally, the diffuser plate 12 has a beveled area 125 on the side adjacent to the flip-chip film 16, that is, the diffuser plate 12 has a beveled area 125 on the non-cut edge side of the display device 10.

[0088] Alternatively, along the arrangement direction of the display panel 11 and the diffuser plate 12, the support portion 142 is inclined relative to the main body portion 141. Specifically, the end of the support portion 142 away from the main body portion 141 may be closer to the flip-chip film 16 than the end of the support portion 142 connected to the main body portion 141.

[0089] Alternatively, the end of the support portion 142 away from the main body portion 141 may extend along the arrangement direction of the display panel 11 and the diffuser plate 12, thereby providing a bottoming effect for the diffuser plate 12 when it is placed vertically.

[0090] Specifically, in this embodiment, a sloped area 125 is provided on the side of the diffuser plate 12 adjacent to the flip-chip film 16, and the back plate 14 is provided with the support portion 142 corresponding to the sloped area 125 of the diffuser plate 12. When the display device 10 is placed vertically, the side of the display device 10 with the flip-chip film 16 is usually the ground side of the display device 10. The support portion 142 can cooperate with the sloped area 125 of the diffuser plate 12 and provide support for the diffuser plate 12, thereby avoiding the failure of the adhesive backing due to long-term shear force between the back plate 14 and the diffuser plate 12, and thus ensuring the reliability of the display device 10.

[0091] Please see Figure 5 , Figure 5 This is a schematic cross-sectional view of the display device along line AA according to Embodiment 3 of this application. The optical film 13 has a thickness range D2, wherein 0.2mm≤D2≤2mm.

[0092] Optionally, the thickness range D2 can be understood as the maximum thickness value of the optical film 13 along the arrangement direction of the display panel 11 and the optical film 13.

[0093] Optionally, the thickness range D2 can be, but is not limited to, 0.2mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm or other values, as long as 0.2mm≤D2≤2mm is satisfied.

[0094] In this embodiment, the thickness range of the optical film 13 is 0.2mm≤D2≤2mm, which satisfies the optical control effect of the display device 10 while also taking into account the design requirements of the display device 10 to be thinner and lighter.

[0095] Optionally, the optical film 13 can be an independent film, or it can be formed by attaching optical adjustment controls to the upper and lower sides of the glass support plate. This application does not limit this.

[0096] Please see Figure 6 , Figure 6 This is a cross-sectional structural diagram of the display device along line AA according to Embodiment 4 of this application. The display device 10 further includes a first adhesive layer 18, which is sandwiched between the diffuser plate 12 and the back plate 14.

[0097] Optionally, in one embodiment of this application, the first adhesive layer 18 may be an adhesive backing. Specifically, during the assembly of the display device 10, an adhesive backing is applied to the side of the diffuser plate 12 adjacent to the back plate 14, or to the side of the back plate 14 adjacent to the diffuser plate 12. The adhesive backing may be white and semi-transparent, allowing light to diffuse after passing through it; that is, the adhesive backing is a light-transmitting material. Further optionally, the adhesive backing may be cured by, but is not limited to, methods such as UV curing or thermosetting.

[0098] Optionally, in another embodiment of this application, the first adhesive layer 18 may be an α-adhesive and a β-adhesive. Specifically, during the assembly of the display device 10, an α-adhesive is applied to the side of the back plate 14 adjacent to the diffuser plate 12, and a β-adhesive is applied to the side of the diffuser plate 12 adjacent to the back plate 14. After the back plate 14 and the diffuser plate 12 are bonded together, the α-adhesive and the β-adhesive come into contact. The α-adhesive and the β-adhesive may contain different reactive monomers and can undergo a chemical reaction at room temperature to cure. It is understood that the α-adhesive and the β-adhesive can also be cured by high-temperature heating or UV irradiation, thereby accelerating the curing rate of the α-adhesive and the β-adhesive and improving the production efficiency of the display device 10.

[0099] Optionally, the thickness range D3 can be understood as the maximum thickness value of the adhesive layer along the arrangement direction of the back plate 14 and the diffuser plate 12.

[0100] Further optionally, the thickness range D3 can be, but is not limited to, 0.05mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, or other values, as long as 0.05mm≤D3≤0.7mm is satisfied.

[0101] In this embodiment, a first adhesive layer 18 is provided between the back plate 14 and the diffuser plate 12 to securely fix the back plate 14 and the diffuser plate 12. The first adhesive layer 18 is made of a light-transmitting material, thereby ensuring the optical utilization efficiency and optical display effect of the display device 10. Furthermore, the thickness D3 of the first adhesive layer 18 satisfies 0.05mm ≤ D3 ≤ 0.7mm, allowing the back plate 14 to firmly bond the diffuser plate 12 while also meeting the requirements of a thin and light design for the display device 10.

[0102] Optionally, in other embodiments of this application, the display device 10 may also have a middle frame, which may be used together with the back plate 14 to support the diffuser plate 12 and the display panel 11, and the first adhesive layer 18 may also be disposed between the middle frame and the diffuser plate 12 to fix the diffuser plate 12.

[0103] Please see Figure 7 , Figure 7 This is a cross-sectional structural diagram of the display device according to Embodiment 5 of this application along line AA. The display device 10 further includes a second adhesive layer 19, which is sandwiched between the display panel 11 and the diffuser plate 12. The second adhesive layer 19 is made of a light-transmitting material, and the orthographic projection of the second adhesive layer 19 onto the diffuser plate 12 covers the first surface 121.

[0104] Optionally, the second adhesive layer 19 can be an optical clear adhesive (OCA). The OCA adhesive can have high light transmittance and good bonding strength. Understandably, the second adhesive layer 19 can also be made of other types of materials, as long as it satisfies good light transmittance and firmly bonds the display panel 11 to the diffuser plate 12. The choice of material for the second adhesive layer 19 should not be a limitation on the display device 10 provided in this embodiment.

[0105] In this embodiment, the second adhesive layer 19 is sandwiched between the display panel 11 and the diffuser plate 12, and fixes the display panel 11 and the diffuser plate 12 together, thereby enabling the display device 10 to achieve an extremely narrow bezel design. Furthermore, the orthographic projection of the second adhesive layer 19 onto the diffuser plate 12 covers the first surface 121 of the diffuser plate 12; in other words, the first surface 121 falls within the range of the orthographic projection of the second adhesive layer 19 onto the diffuser plate 12. The display panel 11 and the diffuser plate 12 are fixed using a full-adhesion method, which enhances the fixing effect of the display panel 11, allowing it to be more firmly bonded to the diffuser plate 12, thereby improving the reliability of the display device 10.

[0106] Optionally, in other embodiments of this application, the display panel 11 and the diffuser plate 12 can also be bonded and fixed together by a transparent frame adhesive, which can be disposed adjacent to the peripheral side of the display panel 11.

[0107] Please see Figure 1 and Figure 8 , Figure 8This is a cross-sectional structural diagram of the display device along line AA according to Embodiment Six of this application. This application also provides an electronic device 1, which includes at least two interconnected display devices 10. A seam 20 is provided between adjacent interconnected display devices 10, and each display device 10 has a first non-display area 113, a display area 112, and a second non-display area 114 arranged sequentially. The width of the seam 20 is equal to the sum of the width of the first non-display area and the width of the second non-display area.

[0108] Optionally, the electronic device 1 can be, but is not limited to, any electronic product with display function such as a laptop, monitor, television, mobile phone, or tablet computer.

[0109] Optionally, the electronic device 1 may include two, three, four, or more of the display devices 10. The display devices 10 can be spliced ​​together to form a video wall.

[0110] Understandably, the display device 10 has a display area 112 and a non-display area surrounding the display area 112. The first non-display area 113 can be the non-display area of ​​the display device 10 adjacent to its non-aligned edge, and the second non-display area 114 can be the non-display area of ​​the display device 10 adjacent to its aligned edge. When two adjacent display devices 10 are spliced ​​together, a splicing seam 20, i.e., a non-display area, will exist between the two display devices 10. Specifically, the aligned edge of one display device 10 can be spliced ​​together with the non-aligned edge of another display device 10, so that the width of the first non-display area 113 plus the width of the second non-display area 114 constitutes the width of the splicing seam 20.

[0111] Optionally, the display device 10 includes a display panel 11, a diffuser plate 12, and an optical film 13. The diffuser plate 12 further has a receiving cavity 123, which has an opening 1231 on the second surface 122 of the diffuser plate 12. The optical film 13 is at least partially received within the receiving cavity 123 of the diffuser plate 12, and the optical film 13 is detachably connected to the diffuser plate 12. The diffuser plate 12 can receive the optical film 13 through the receiving cavity 123 and limit the optical film 13, thereby eliminating the need for adhesive material between the diffuser plate 12 and the optical film 13. When the optical film 13 needs to be replaced, the optical film 13 can be directly removed from the receiving cavity 123 of the diffuser plate 12. Compared with the traditional method of bonding the optical film 13 to the surface of the diffuser plate 12, the display device 10 can replace the optical film 13 without damaging the diffuser plate 12 and the display panel 11, thereby effectively saving the maintenance costs of the display device 10 and the electronic device 1.
