Description

Technical Field

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

[0002] A display device is an output device that displays visible information; for example, it can be a television, mobile phone, computer, electronic watch, etc. A display device includes a display module, a bezel, and a housing, with the bezel positioned between the display module and the housing. The bezel provides some cushioning when the housing is subjected to external pressure. However, due to the trend towards ultra-thin and lightweight display devices, the bezel can no longer adequately protect the display module. Summary of the Invention

[0003] The purpose of this disclosure is to provide a display device that addresses the problem that the frame cannot adequately protect the display module in the context of the trend towards ultra-thin and lightweight display devices.

[0004] To achieve the above objectives, the embodiments of this disclosure provide the following technical solutions:

[0005] A display device is provided. The display device includes a display module, a frame, and a housing. The display module has opposing display sides and non-display sides. The frame includes a frame body and a protrusion; the frame body is disposed around the circumferential edge of the display module and has a first surface located on the non-display side of the display module; the protrusion protrudes from the first surface along the thickness direction of the display module. The housing includes a side plate and a bottom plate connected to each other; the side plate is disposed around the frame along the circumferential direction of the frame; the bottom plate is distributed with the frame in the thickness direction of the display module and has a second surface and a groove; the second surface faces the first surface, and the opening of the groove is located on the second surface; the protrusion extends into the groove from the opening.

[0006] The frame includes a frame body and a protrusion. The frame body is disposed around the circumferential edge of the display module, allowing the frame body to include the display module. The protrusion protrudes from a first surface, thus ensuring the frame body effectively protects the display module. The protrusion extends into a groove, effectively increasing the thickness of the frame without changing the thickness of the display device (i.e., conforming to the trend towards ultra-thinness), thereby increasing the frame's strength. Therefore, when the frame (or base plate) is subjected to external pressure, the frame in this embodiment significantly enhances its ability to protect the display module (i.e., it can effectively protect the display module). Furthermore, the protrusion extending from the slot into the groove serves a positioning function, facilitating the assembly of the frame and the frame body.

[0007] Optionally, the display module includes a flexible display panel and a spacer. The flexible display panel includes a display portion, a bending portion, and a folding portion. The spacer is stacked on top of the display portion. The bending portion bends the folding portion onto the side of the spacer away from the display portion, and the bending portion is covered by a frame body. Along the thickness direction of the display module, a gap exists between the first surface and the second surface at the position corresponding to the bending portion.

[0008] Optionally, the recess has a first groove wall and a second groove wall disposed opposite to each other; the first groove wall is farther from the second groove wall relative to the center line of gravity of the display module. The display device also includes a sealing layer. The sealing layer is disposed between the side plate and the frame body, and extends sequentially between the protrusion and the first groove wall, and between the protrusion and the second groove wall.

[0009] Alternatively, the sealing layer extends to the opening of the groove; or, the sealing layer extends beyond the groove.

[0010] Optionally, along the thickness direction of the display module and in the direction from the display side to the non-display side, the cross-sectional area of ​​the protrusion gradually decreases.

[0011] Optionally, the protrusion has a first side surface, a third surface, and a second side surface connected in sequence; the first side surface and the second side surface are opposite to each other; the included angle between the third surface and the second side surface is in the range of 120° to 150°.

[0012] Optionally, along the thickness direction of the display module, the orthographic projection of the third surface onto the plane where the display module is located does not overlap with the display module.

[0013] Optionally, the first side is farther away from the second side than the center line of the display module; the first side is flush with the outer side of the frame body.

[0014] Optionally, the third surface is parallel to the first surface, and the first side surface is perpendicular to both the first and third surfaces.

[0015] Optionally, the height of the protrusion is 0.3 to 0.5 mm along the thickness direction of the display module.

[0016] Optionally, the display module and the frame can be integrated into one unit. Attached Figure Description

[0036] This disclosure provides a display device. A display device refers to a product with image display functionality. Exemplarily, it can be one of the following: a monitor, television set, billboard, digital photo frame, drawing screen, laser printer with display functionality, telephone, mobile phone, personal digital assistant (PDA), digital camera, portable camcorder, viewfinder, monitor, navigator, in-vehicle display device, large-area wall display, home appliance, information query device (such as business query device for e-government, banks, hospitals, power companies, etc.), and monitor. As another example, the display device can be any of the following wearable display devices: an electronic watch (e.g., a phone watch), a smart bracelet, an augmented reality (AR) head-mounted display device, and a virtual reality (VR) head-mounted display device.

[0037] Figure 1 This is a structural diagram of a display device according to an embodiment of the present disclosure. Figure 2 for Figure 1 The cross-sectional view at line AB. Figure 3 for Figure 2 A magnified view at point C. See also Figure 1 , Figure 2 and Figure 3 The display device includes a display module 3, a frame 2, and a housing 1.

[0038] Display module 3 can be a component configured to display a screen. Display module 3 has a display side (e.g., the top side) and a non-display side (e.g., the bottom side). The display side can be the side of display module 3 that can display a screen, and the non-display side can be the side opposite to the display side.

[0039] The display module 3 may include a display panel 31. Depending on the display principle, the display panel 31 can be any of the following self-emissive display panels: Organic Light Emitting Diode (OLED), Quantum Dot Light Emitting Diodes (QLED), and MiniLED or MicroLED; it can also be a Liquid Crystal Display (LCD) panel. Depending on the bendability of the display panel 31, it can be a flexible or rigid display panel.

[0040] In some embodiments, the display panel 31 may be a flexible display panel, which includes a display portion 311, a bending portion 312, and a folding portion 313. In this case, the display module 3 may further include a spacer 32. The spacer 32 is stacked on top of the display portion 311. The bending portion 312 bends the folding portion 313 onto the side of the spacer 32 away from the display portion 311. That is, the spacer 32 is configured to space the display portion 311 and the folding portion 313 apart.

[0041] The spacer 32 may include a heat dissipation assembly 322. Exemplarily, the heat dissipation assembly 322 is disposed between the display portion 311 and the folding portion 313 to dissipate heat from the display portion 311. In some examples, the heat dissipation assembly 322 may include an adhesive layer, a buffer layer, and a thermally conductive layer.

[0042] The thermally conductive layer may include a thermally conductive material (hereinafter referred to as the thermally conductive material), which is intended to mean a material commonly referred to as a good thermal conductor or known to have heat transfer properties. In one example, the thermally conductive layer may include a thermally conductive metallic material; for example, it may include metals such as copper (Cu), gold (Au), silver (Ag), aluminum (Al), magnesium (Mg), or nickel (Ni), or an alloy containing at least one of the aforementioned metals. In another example, the thermally conductive layer may include a thermally conductive carbon-based material; for example, it may include graphite, diamond, carbon fiber, etc. Additionally, the thermally conductive layer may include a thermally conductive polymer material, such as thermal grease. However, the thermally conductive layer is not limited to the materials described above and may include combinations of the aforementioned materials or other materials not mentioned above.

[0043] The adhesive layer can be an embo, which provides adhesion and air release while maintaining flexibility without affecting the flexibility of the product containing it. Alternatively, the adhesive layer can be composed of an adhesive (also called a glue) or a double-sided tape containing an adhesive. The adhesive can include: rubber-based adhesives, acrylic adhesives, urethane adhesives, silicone adhesives, olefin adhesives, resin or epoxy adhesives, etc.

[0044] The material of the cushioning layer may include a cushioning material (hereinafter referred to as cushioning material), which is intended to refer to a material commonly referred to as a good cushion or known to have a cushioning effect. The cushioning material may include cushioning foam or cushioning tape, etc. Cushioning foam may be, for example, at least one of PU foam, EVA foam, XPE foam, and IXPE foam, or any combination thereof. Cushioning tape may include a thermally conductive resin layer (e.g., a synthetic thermally conductive resin layer), etc.

[0045] In some examples, the display portion 311, adhesive layer, thermally conductive layer, buffer layer, and folding portion 313 are stacked sequentially. The buffer layer serves to cushion the display portion 311 and reduce the pressure exerted by the folding portion 313 on it.

[0046] The spacer 32 may also include a fixing block 321. The display part 311, the heat dissipation assembly, the fixing block 321, and the folding part 313 are stacked in sequence. The fixing block 321 prevents the bending part 312 from breaking or cracking, and keeps the display part 311 and the folding part 313 as horizontal as possible.

[0047] In some examples, the fixing block 321 may include a material with hardness (hereinafter referred to as hardness material). The hardness material may include, for example, any one or a combination of resin and silicone. The resin may include phenolic amine, alicyclic amine cured epoxy resin, polyamide, aliphatic amine or polyether amine, etc.

[0048] In some embodiments, the display module 3 may further include a driving circuit, specifically a driving IC, such as a source driver IC or a display driver integrated circuit (DDIC). The driving circuit is coupled to the display panel, for example, it may be attached to the folding portion 313 of the flexible display panel 31, and is configured to provide data signals to the display panel 31.

[0049] For example, the display module 3 may also include a circuit board, such as a flexible circuit board. This circuit board may be attached to the folding portion 313 of the flexible display panel 31 and coupled to the driving circuit, and configured to transmit image data to the driving circuit, so that the driving circuit generates a corresponding data signal based on the image data.

[0050] In some embodiments, the display module 3 may further include a protective layer 33 covering the bent portion 312. The protective layer 33 may be a colloid. The colloid is liquid before curing and has good wettability, which enables it to better form a protective layer, greatly enhancing the maneuverability of both ends of the bent portion 312 and simplifying the manufacturing process.

[0051] The frame 2 includes a frame body 21 and a protrusion 22. Exemplarily, the frame body 21 and the protrusion 22 can be integrally formed, meaning they are in direct contact and normally inseparable. For example, the frame body 21 and the protrusion 22 can be integrally formed by injection molding. Alternatively, the frame body 21 and the protrusion 22 can be two parts fixedly connected together, for example, by using double-sided tape, glue, or other methods.

[0052] The frame body 21 is disposed around the circumferential edge of the display module 3; in this way, the circumferential edge of the display module 3 is wrapped by the frame body 21, so that the display module 3 is fixedly connected to the frame body 21. Exemplarily, the display module 3 and the frame 2 can be integrally disposed, in direct contact, and are generally inseparable. For example, the display module 3 and the frame 2 (or the frame body 21) can be integrally disposed by injection molding, so that the display module 3 and the frame 2 become a single unit, facilitating installation. Exemplarily, the bent portion 312 of the display panel 31 (specifically a flexible display panel) is covered by the frame body 21. For example, a portion of the frame body 21 is located between the bent portion 312 and the spacer 32, and another portion is located on the side of the bent portion 312 away from the spacer 32, so that the flexible display panel 31 is fixedly connected to the frame body 21.

[0053] The frame body 21 has a first surface 211, which is located on the non-display side (below) of the display module 3. Thus, the lower surface of the circumferential edge of the display module 3 is covered by the frame body 21, demonstrating that the frame body 21 can protect the circumferential edge of the display module 3 to a certain extent. Along the thickness direction of the display module 3, a protrusion 22 protrudes from the first surface 211. The protrusion 22 effectively increases the thickness of the frame 2, thereby enhancing its strength and further strengthening its ability to protect the circumferential edge of the display module 3.

[0054] For example, the shape of the frame body 21 can be a sealing ring. Figure 2 The circumferential edge of the display module 3 can be approximately circular; correspondingly, the frame body 21 can be approximately a sealing ring. Alternatively, the circumferential edge of the display module 3 can be approximately rectangular; correspondingly, the frame body 21 can be approximately a sealing rectangular ring.

[0055] Furthermore, when the display panel 31 has a bend 312, the thickness of the display module 3 at the bend 312 is greater than the thickness of the display module 3 at other locations; for example... Figure 2 In the display module 3, the thickness of the left side is greater than that of the right side. Correspondingly, the thickness of the frame body 21 below the bend 312 is less than the thickness of the frame body 21 at other locations. Therefore, the protective effect of the frame body 21 on the bend 312 is relatively weak.

[0056] Based on this, in some embodiments, the protrusion 22 is provided at least on the portion of the frame body 21 used to cover the bent portion 312, thereby strengthening the protection of the bent portion 312 and improving the drop resistance of the display device. For example, the protrusion 22 may also be provided in a sealing ring along the circumference of the frame body 21 to provide enhanced protection for the portion of the display module 3 outside the bent portion 312 in the circumferential edge.

[0057] The material of the frame 2 can be a UV adhesive, injection molding adhesive, or glass melt adhesive (Frit adhesive) or other adhesives with water and oxygen barrier capabilities.

[0058] The frame 1 includes a side plate 11 and a bottom plate 12 connected together. In some examples, the side plate 11 and the bottom plate 12 are integrally formed. The side plate 11 is arranged around the frame 2 along its circumference. The bottom plate 12 and the frame 2 are distributed in the thickness direction of the display module 3, for example, the side plate 11 and the bottom plate 12 are arranged perpendicularly. The bottom plate 12 has a second surface and a groove 121. The second surface is directly opposite the first surface 211, meaning that in the thickness direction of the display module 3, the orthographic projection of the second surface onto the plane containing the first surface 211 overlaps with the first surface 211. The opening of the groove 121 is located on the second surface; the protrusion 22 extends into the groove 121 from the opening. The protrusion 22 is installed in the groove 121, which can play a positioning role and facilitate the assembly of the frame 2 and the frame 1. Furthermore, this eliminates the need to reserve space between the frame body 21 and the base plate 12 for placing the protrusion 22, so the overall thickness of the assembled frame 2 and frame 1 does not need to be increased, thus ensuring the thinness of the display device (i.e. the whole machine).

[0059] This disclosure also provides a comparison scheme. Figure 4 for Figure 1 Another cross-sectional view at line AB. See also Figure 4The display device in the comparative scheme includes a frame 1', a plastic frame 2', and a display module 3. The frame 1' and the plastic frame 2' are fixedly connected, and the plastic frame 2' and the display module 3 are integrally formed. The plastic frame 2' in the comparative scheme is equivalent to the plastic frame body 21 in this embodiment. Therefore, compared to the plastic frame 2' in the comparative scheme, the plastic frame 2 in this embodiment further includes a protrusion 22, and the protrusion 22 is connected to the plastic frame body 21. In this way, in this embodiment, without changing the thickness of the display device, the connection between the plastic frame 2 (e.g., the plastic frame body 21) and the display module 3 is maintained, while the thickness of the plastic frame 2 is effectively increased, thereby increasing the strength of the plastic frame 2. Therefore, when the frame 1 (e.g., the base plate 12) is subjected to pressure, the plastic frame 2 in this embodiment enhances its ability to protect the display module 3, thus providing excellent protection for the display module 3.

[0060] See in some examples Figure 2 Along the thickness direction of display module 3 ( Figure 2 (As shown in the vertical direction), the height H1 of the frame body 21 is 1.0 to 1.4 mm (e.g., 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, etc.). Based on this, along the thickness direction of the display module 3, the height H2 of the protrusion 22 is 0.3 to 0.5 mm (e.g., 0.3 mm, 0.4 mm, 0.5 mm, etc.).

[0061] In some embodiments, see Figure 2 and Figure 3 Along the thickness direction of the display module 3, and in the direction from the display side to the non-display side (i.e., from top to bottom), the cross-sectional area of ​​the protrusion 22 gradually decreases, thus obtaining a protrusion 22 that is wider at the top and narrower at the bottom. This protrusion 22 still serves to enhance the strength of the frame 2. Furthermore, when the frame body 21, the protrusion 22, and the display module 3 are integrally formed by injection molding, the protrusion 22 that is wider at the top and narrower at the bottom is easier to demold when removing the mold (i.e., demolding) along the thickness direction of the display module 3. This is compared to the protrusion 22 that is narrower at the top and wider at the bottom.

[0062] Here, the cross-section can be understood as a plane perpendicular to the thickness direction of the display module 3 (e.g., Figure 3 The third surface shown is a cross-section of the protrusion 22.

[0063] Two cross-sections of the protrusion 22 at different levels are defined as the first cross-section and the second cross-section, respectively, wherein the first cross-section is farther from the first surface of the frame body than the second cross-section. The area of ​​the first cross-section is less than or equal to the area of ​​the second cross-section. In some examples, the shape of the protrusion can be as follows: Figure 3 The trapezoid in the middle.

[0064] For example, see Figure 3 The area of ​​the first cross-section is smaller than the area of ​​the second cross-section. The orthographic projection of the second cross-section onto the plane containing the first surface overlaps the orthographic projection of the first cross-section onto the plane containing the first surface.

[0065] For example, Figure 5 This is an alternative diagram for the protrusion 22. See also... Figure 5 The area of ​​the first cross-section is equal to the area of ​​the second cross-section. The orthographic projection of the second cross-section onto the plane containing the first surface coincides with the orthographic projection of the first cross-section onto the plane containing the first surface. In some examples, the shape of the protrusion can be as follows: Figure 5 The steps are in the middle.

[0066] In some examples, the first cross-section may be the third surface (the smallest first cross-section). The second cross-section may be the plane enclosed by the outline of the root of the protrusion 22 (i.e., the intersection of the protrusion 22 and the first surface 211) (the largest second cross-section).

[0067] For example, see Figure 6 The protrusion 22 has a first side surface 221, a third surface 222, and a second side surface 223 connected in sequence. The first side surface 221 and the second side surface 223 are opposite each other, meaning that the first side surface 221 and the second side surface 223 are located on both sides of the third surface 222 (e.g., left and right, or right and left). Based on the top-wide and bottom-narrow protrusion 22, when the frame body 21, the protrusion 22, and the display module 3 are integrally formed by injection molding, the included angle between the third surface 222 and the second side surface 223 is in the range of 120° to 150° (e.g., 120°, 130°, 140°, 150°) when removing the mold along the thickness direction of the display module 3, making it easier to remove the mold (i.e., make a draft).

[0068] For example, compared to the center line of display module 3 (such as...) Figure 1 or Figure 2The center of gravity line (G) shown in the diagram indicates that the first side 221 is far from the second side 223, meaning that the first side 221 and the second side 223 are located to the left and right of the third surface 222, respectively. The center of gravity line refers to the vertical line drawn through the center of gravity point; that is, the center of gravity line extends along the thickness direction (vertical direction) of the display module 3. In some examples, the display module 3 has a regular shape, in which case the center of gravity line coincides with the center line. The first side surface 221 is flush with the outer side surface of the frame body 21. This results in less overlap between the protrusion 22 and the display module 3 along the thickness direction of the display module 3 (meaning the projection of the protrusion 22 onto the plane of the first surface 211 overlaps with the projection of the display module 3 onto the same plane). Therefore, when the protrusion 22 is compressed, the compression exerted by the protrusion 22 on the frame body 21 at the intersection with the display module 3 is less, thus effectively protecting the display module 3. Furthermore, this design allows the outer side surface of the frame 2 to be a vertical plane, and the side plate 11 to be a vertical plate, simplifying the structure of the side plate 11 and the frame 2 and facilitating assembly.

[0069] For example, the third surface 222 is parallel to the first surface 211, and the first side surface 221 is perpendicular to the first surface 211 and the third surface 222, so that the shape of the protrusion 22 can be a right trapezoid. When the frame body 21, the protrusion 22 and the display module 3 are integrally formed by injection molding, the right trapezoidal shape of the protrusion 22 makes it easier to remove the mold (i.e., draft) when removing the mold along the thickness direction of the display module 3.

[0070] For example, along the thickness direction of the display module 3, the orthographic projection of the third surface 222 onto the plane where the display module 3 is located does not overlap with the display module 3 (i.e., there is no intersection area). As a result, along the thickness direction of the display module 3, the overlapping area between the protrusion 22 and the display module 3 is small (i.e., the orthographic projection of the protrusion 22 at the second side 223 onto the plane where the display module 3 is located can overlap with the display module 3) or there is no overlapping area. Therefore, when the protrusion 22 is compressed, the compression of the frame body 21 at the overlapping area between the protrusion 22 and the display module 3 is smaller or non-existent, thus effectively protecting the display module 3.

[0071] In some embodiments, see Figure 3 and Figure 6Along the thickness direction of the display module 3, at the position corresponding to the bending portion 312, there is a gap 5 between the first surface 211 and the second surface. When an external force compresses the frame 1 (e.g., the base plate 12), the base plate 12 first compresses the protrusion 22 through the groove 121, and then the protrusion 22 compresses the frame body 21 located at the position of the protrusion 22. Since there is a gap 5 between the first surface 211 and the second surface, the second surface of the base plate 12 located at the gap 5 will not contact the first surface 211 of the frame body 21 located at the gap 5. In this way, most of the external force acting on the frame 1 (base plate 12) is absorbed by the protrusion 22 and acts on the frame body 21 located at the position of the protrusion 22. Therefore, the compression of the frame body 21 located at the position of the protrusion 22 to the frame body 21 located at the bending portion 312 is small or non-existent, thereby reducing the compression on the bending portion 312 of the flexible display panel 31 and protecting the flexible display panel 31.

[0072] In some embodiments, see Figure 6 The groove 121 has a first groove wall 1211 and a second groove wall 1213 disposed opposite to each other; relative to the center line of gravity of the display module 3, the first groove wall 1211 is far away from the second groove wall 1213 (the first groove wall 1211 is...). Figure 6 The left groove wall shown in the figure, the second groove wall 1213 is Figure 6 The groove 121 also has a third groove wall 1212 (the third groove wall 1212 is shown in the right groove wall). Figure 6 (The lower groove wall shown in the figure) The third groove wall 1212 is located between the first groove wall 1211 and the second groove wall 1213, and is connected to the first groove wall 1211 and the second groove wall 1213.

[0073] In some examples, the first groove wall 1211 is perpendicular to the third groove wall 1212. The angle between the third groove wall 1212 and the second groove wall 1213 is 120° to 150°. The third groove wall 1212 is parallel to the first surface 211.

[0074] To improve the waterproof performance between the plastic frame 2 and the frame 1 Figure 7 for Figure 3 Structural diagram of the intermediate sealing layer. See also... Figure 3 , Figure 6 and Figure 7 The display device also includes a sealing layer 4. The sealing layer 4 is disposed between the side plate 11 and the frame body 21, so that the sealing layer 4 can seal the frame body 21 of the frame 2 and the side plate 11 of the frame 1. The sealing layer 4 also extends sequentially between the protrusion 22 and the first groove wall 1211, between the protrusion 22 and the third groove wall 1212, and between the protrusion 22 and the second groove wall 1213. Figure 8 for Figure 4 Structural diagram of the intermediate sealing layer. Based on this, see... Figure 8 In the comparative scheme, a sealing layer 4' also exists between the frame 2' and the frame 1', which seals the frame 2' and the frame 1'. Due to the structure of the frame 2' and the frame 1', the vertical cross-section of the sealing layer 4' is approximately "L" shaped. In this embodiment, the sealing layer 4 extends further between the protrusion 22 (second side 223) and the second groove wall 1213, making the sealing layer 4 in this embodiment, based on the "L" shape of the sealing layer 4' in the comparative scheme, as... Figure 7 The portion shown is bent upwards. As a result, the sealing path of the sealing layer 4 in this embodiment is more complex than that of the sealing layer 4' in the comparative embodiment, thus providing better protection against moisture and impurities.

[0075] For example, the sealing layer 4 extends to the opening of the groove 121. For another example, the sealing layer 4 extends beyond the groove 121. In this way, the sealing layer 4 fills the space between the protrusion 22 (second side 223) and the second groove wall 1213, thereby improving the sealing effect of the sealing layer 4.

[0076] In some examples, the protrusion 22 and the groove 121 are adapted to fill the gap in the sealing layer 4, resulting in a more uniform thickness of the sealing layer 4. In one possible implementation, the sealing layer 4 can be formed by injecting injection molding compound into the gap.

[0077] In some embodiments, see continue to see Figure 1 , Figure 2 and Figure 3 The display device also includes a protective screen 6, which is disposed on the side of the frame body 21 opposite to the first surface 211, and a side panel 11 is disposed around the protective screen 6. A sealing layer 4 extends between the side panel 11 and the protective screen 6. In some examples, the protective screen 6 may be made of glass. The display device also includes a back cover that can be fastened to the base plate 12. The display device may be circular in shape.
