Description

Technical Field

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

[0002] OLED display panels have many advantages such as self-luminescence, low driving voltage, high luminous efficiency, short response time, high contrast, wide range of use, flexible display and large-area full-color display. They are widely used in the display field, lighting field and smart wearable field.

[0003] With the development of flexible display technology, more and more flexible display screens are used, such as curved screens and folding screens. When the OLED panel is a flexible screen, when the external force extrusion / impact reaches the stress limit of the inorganic film layer and the metal film layer, cracks will occur, and even the metal wire will break. The pixels at the stress position will be always bright, that is, broken bright spots will appear. In order to improve the ability of the OLED flexible screen to resist external force extrusion or impact, it is usually necessary to release part of the stress by adding a film layer with buffering and extrusion impact force on the back of the screen in addition to simple support of flexible PI and PET, so as to reduce the stress on the screen. The strength of the foam with buffering performance is proportional to the thickness. The higher the strength of the foam, the higher the thickness of the foam. The high-thickness foam will increase the thickness of the screen, which is contrary to the trend of thinning the screen. Silicone gel material is used to replace foam to achieve the anti-extrusion / impact performance of the panel under the thinner film layer stacking structure, which can still meet customer needs. However, the silicone gel solution is very easy to produce inevitable visible front mold printing during module support and whole machine assembly, which affects the front display effect of the panel. Summary of the invention

Exceptions to this definition will only occur when the combination of elements, functions, steps or operations is inherently mutually exclusive in some way.

[0039] As described in the background technology, the thickness of the foam in the prior art that meets the compression and impact resistance required by the display panel is too thick, which is not conducive to the thinning of the display panel; and the use of silicone gel material instead of foam is very likely to produce inevitable visible mold prints on the front during the assembly of the whole machine, affecting the front display effect of the display panel.

[0040] To solve the above problems, an embodiment of the present invention provides a display module. Figure 1 FIG. 1 shows a schematic diagram of the structure of a display module provided by an embodiment of the present invention. Figure 1 As shown, the display module includes a cover plate 10, a display panel 20 and a support assembly 30. The display panel 20 is arranged between the support assembly 30 and the cover plate 10. The support assembly 30 includes a foam 31. The foam 31 includes a first foam 311 and a second foam 312. The first density of the first foam 311 is greater than the second density of the second foam 312.

[0041] Foam is a material made of foamed plastic particles. After the plastic particles are foamed, multiple pores are formed inside them. Air flows inside the pores. These pores are compressible, which provides cushioning capacity for the foam. The more pores there are and the larger the volume, the better the air flow in the pores, and the better the cushioning performance of the foam. However, the pressure it withstands is relatively weakened, and it is easy to deform. On the contrary, when the number of pores is fewer and the volume is smaller, the air flow in the pores is worse, and the cushioning performance of the foam is poor, but the pressure it withstands is increased and it is not easy to deform.

[0042] In the embodiment of the present invention, the foam 31 can play a role in buffering and shading. The density of the foam refers to the mass of the foam per unit volume. The greater the density of the foam, the fewer the number of pores inside it and the smaller the volume of the pores. High-density foam has higher hardness and strength, excellent resistance to compression deformation, and can maintain shockproof protection for a long time. Low-density foam is soft and easy to compress, but still has a certain elasticity. For the specific density of the first foam 311 and the second foam 312, those skilled in the art can set it according to the size of the display panel 20, the customer's requirements for buffering performance and anti-extrusion performance, etc., and no specific limitation is made here.

[0043] In the embodiment of the present invention, the foam 31 used to support the display module includes a first foam 311 with a first density and a second foam 312 with a second density, and the first density of the first foam 311 is greater than the second density of the second foam 312. The number of pores in the first foam 311 is relatively small, the volume of the pores in the first foam 311 is relatively small, the first foam 311 has a large strength and is not easily deformed; the number of pores in the second foam 312 is relatively large, the volume of the pores is relatively large, the second foam 312 has a small strength and is easily deformed. Therefore, when the foam 31 is configured to include a first foam 311 with high density and a second foam 312 with low density, the first foam 311 can be used to provide good rigid protection for the display module 100 due to its high strength and non-deformation properties, so that the display module 100 is not easily compressed in scenarios such as falling, squeezing or collision, and has good and stable support; the second foam 312 can be used to provide good flexible protection for the display module 100 due to its good buffering properties, so that the display module 100 can absorb or dissipate part of the impact force and squeezing force in scenarios such as falling, squeezing or collision, reduce the force transmitted to the display panel 20, and ensure that the panel has strong impact resistance and squeezing resistance; the use of the first foam 311 and the second foam 312 with different densities can also provide the display module 100 with good support and buffering properties without increasing the thickness of the display module 100, which is conducive to realizing a thinning design of the display panel.

[0044] Furthermore, the display panel 20 is used to display images and is a composite structure formed by stacking a plurality of film layers with different functions. Figure 2FIG. 1 is a schematic diagram showing the structure of a display panel provided by an embodiment of the present invention. Figure 2 As shown, the display panel 20 includes a substrate 21, a driving circuit layer 22, a light emitting layer 23 and an encapsulation layer 24 which are stacked in sequence.

[0045] Specifically, the substrate 21 may be a flexible substrate or a rigid substrate. The material of the rigid substrate may be sapphire, silicon dioxide or glass, etc. The material of the flexible substrate may be, for example, any one of ultra-thin glass (UTG), metal foil, polymer plastic or glass fiber reinforced plastic. Among them, the metal foil includes stainless steel foil, aluminum foil, copper foil, etc. The polymer plastic includes polyimide (PI), polyvinyl alcohol (PVA), polyethylene terephthalate (PET), etc.

[0046] The driving circuit layer 22 includes pixel circuit units arranged in an array, and the light-emitting layer 23 includes a plurality of light-emitting elements corresponding to the plurality of pixel circuit units. A plurality of light-emitting elements of different light-emitting colors form a pixel unit, and each pixel circuit unit is electrically connected to a corresponding light-emitting element to control the light-emitting state of the light-emitting element. The specific light-emitting color of the pixel unit is jointly controlled by the plurality of light-emitting elements of different light-emitting colors inside it, and controlling the light emission of the plurality of pixel units can present the desired display screen.

[0047] Exemplarily, the pixel circuit unit includes multiple thin film transistors (TFTs), storage capacitors and other components, and the driving circuit layer 22 also includes multiple signal lines for transmitting different types of driving signals to each pixel circuit unit. The signal lines may include common potential signal lines, scanning signal lines, data signal lines, power signal lines, etc.

[0048] The light emitting element may include any one of an organic light emitting element, a quantum dot light emitting element, and an inorganic light emitting element. The embodiment of the present invention does not specifically limit the specific type of the light emitting element in the display module.

[0049] The encapsulation layer 24 may be formed by a thin film (Thin Film Encapsulation, TFE for short) process, and the encapsulation layer 24 at least covers the light-emitting device to prevent water vapor and foreign matter from entering the light-emitting element and affecting its display performance.

[0050] Specifically, Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the first foam 311 and the second foam 312 are alternately arranged in the first direction Y or the second direction X.

[0051] For example, Figure 1 As shown, the first foam 311 and the second foam 312 are alternately arranged in the first direction Y, wherein the first foam 311 is arranged between the display panel 20 and the second foam 312. Here, the first direction Y refers to the thickness direction along the display panel 20. By arranging the first foam 311 and the second foam 312 alternately arranged in the first direction Y on the back of the display panel 20, the first foam 311 can provide good rigid support for the display panel 20, and the second foam 312 can absorb and dissipate part of the impact force or extrusion force transmitted to the display panel 20, reduce the impact force or extrusion force transmitted to the display panel 20, and provide good buffering for the display panel 20. Therefore, the first foam 311 and the second foam 312 alternately arranged in the first direction Y can provide good rigid support and flexible buffering for the display module 100 without increasing the thickness of the display module 100, thereby improving the reliability of the display panel and extending the service life of the display module 100.

[0052] It should be noted that the number of layers of the first foam 311 and the second foam 312 alternately stacked in the first direction Y is not limited to the one layer shown above. For example, in another embodiment, the foam 31 may be configured such that a layer of the second foam 312 is disposed between two layers of the first foam 311; or, in another embodiment, the foam 31 may be configured such that a layer of the first foam 311 is disposed between two layers of the second foam 312; or, in another embodiment, two groups of the first foam 311 and the second foam 312 are alternately disposed in the first direction Y. Those skilled in the art may specifically configure the number of layers of the first foam 311 and the second foam 312 alternately disposed in the first direction Y and the specific thickness of the first foam 311 and the second foam 312 alternately disposed in the first direction Y according to the specific size of the display module 100, the specific buffering and shock absorption requirements of the customer for the display module 100, etc., which are not specifically limited here.

[0053] For example, Figure 3 and Figure 4 As shown, in some embodiments, the first foam 311 and the second foam 312 are alternately arranged in the second direction X. Here, the second direction X is the plane direction of the display panel 20. Here, the foam 31 of the same layer includes the first foam 311 and the second foam 312 alternately arranged in the second direction X, so the foam 31 has both support performance and buffer performance, which can provide good rigid support and flexible buffering for the display panel 20, reduce the impact force or extrusion force transmitted to the display panel 20, improve the support performance and buffering performance of the display module 100, improve the reliability of the display module 100, and extend the service life of the display module 100.

[0054] like Figure 3 As shown, the foam 31 includes a first layer of foam 31 (1) and a second layer of foam 31 (2). Both layers of foam 31 are first foam 311 and second foam 312 arranged alternately along the second direction X. The second layer of foam 31 (2) is provided with the position of the second foam 312, and the first foam 311 is arranged on the corresponding first layer of foam 31 (1); the second layer of foam 31 (2) is provided with the position of the first foam 311, and the second foam 312 is arranged on the corresponding first layer of foam 31 (1), that is, Figure 3 The first foam 311 and the second foam 312 are alternately arranged in the first direction Y and the second direction X.

[0055] For example, Figure 4 As shown, the foam 31 includes a first layer of foam 31(1) and a second layer of foam 31(2), and both layers of foam 31 are first foam 311 and second foam 312 arranged alternately along the second direction X. The first layer of foam 31(1) is provided with the first foam 311 at a position where the first foam 311 is arranged, and the second layer of foam 31(2) is provided with the first foam 311 at a position where the first foam 311 is arranged, and the second layer of foam 31(2) is provided with the second foam 312 at a position where the second foam 31(2) is arranged. That is, in the first direction Y, the foam 31 arranged at the corresponding positions of the first layer of foam 31(1) and the second layer of foam 31(2) have the same density, and in the second direction X, the foam 31 arranged at the corresponding positions of the first layer of foam 31(1) and the second layer of foam 31(2) have different densities.

[0056] It should be noted that the number of layers of the first foam 311 and the second foam 312 alternately arranged along the second direction X on the foam 31, and the ratio of the first foam 311 and the second foam 312 on the same layer of foam 31, can be determined by those skilled in the art based on the specific size of the display module 100, the position that is susceptible to squeezing or impact when falling, and the specific buffering and shock absorption requirements of the customer for the display module 100, etc., and are not specifically limited here.

[0057] Furthermore, the first foam 311 and the second foam 312 are alternately arranged in the first direction Y, and specifically, the first foam 311 and the second foam 312 can be arranged on both sides of a flexible substrate. The material of the flexible substrate can be polyimide (PI) or polyethylene terephthalate (PET).

[0058] The first foam 311 and the second foam 312 are alternately arranged in the first direction Y. The specific steps may be: first, a flexible substrate is provided; then, a foaming agent and a polymer melt (such as polyurethane, polyacrylate) are mixed and stirred evenly in a stirring tank to obtain a foamed mixture; next, the foamed mixture is placed on the flexible substrate, for example, the foamed mixture is combined with the PET substrate by a double-tube coater, and finally baked to form a foam layer.

[0059] For forming foams of different densities, the volume of bubbles is controlled by controlling the baking parameters of independent heaters in different areas of the baking box. The baking parameters are factors that affect the volume of bubbles in the foam layer, including but not limited to temperature, pressure, etc. For the different densities of foams 31 at different positions on the same layer of foam 31, the foaming area can be divided by a mold or a partition, and foaming foam structures of different densities can be made so that high-density foams bear more pressure, and low-density foams provide elasticity and cushioning capacity.

[0060] In another embodiment, the first foam 311 and the second foam 312 are alternately arranged in the first direction Y. The first foam 311 and the second foam 312 can be obtained separately by a foam preparation method, and then the first foam 311 and the second foam 312 are connected as a whole through an adhesive layer.

[0061] Furthermore, Figure 5 FIG. 2 shows a schematic diagram of a display module provided by another embodiment of the present invention. Figure 5 As shown, the foam 31 in the display module 100 includes a central area 31A and an edge area 31B surrounding the central area 31A, the first foam 311 is arranged in the central area 31A, and the second foam 312 is arranged in the edge area 31B. In the case of falling, the edge of the display module 100 is likely to be first subjected to impact force or extrusion force, and then the impact force or extrusion force is transmitted to the central area of ​​the display module 100. Therefore, the edge of the display module 100 requires a greater buffer force to absorb or dissipate the impact force in time, and reduce the transmission of the impact force to the inside of the display module 100; and the central area of ​​the display module 100 is large, and a greater support strength is required to resist the impact force or extrusion force. Therefore, the first foam 311 is arranged in the central area 31A and corresponds to the central area of ​​the display module 100, providing high-strength support for the central area of ​​the display module 100 to resist deformation caused by squeezing or impact; the second foam 312 is arranged in the edge area 31B and corresponds to the edge area of ​​the display module 100, providing flexible support for the edge area of ​​the display module 100 to absorb and dissipate the impact force or squeezing force.

[0062] When the display module 100 is a curved screen, the cover plate 10 is a glass with curved surfaces on both sides or four sides and a flat middle area. There is a large stress concentration at the curved edge of the curved screen, and the curved screen is easily broken from the arc when impacted by external force. Therefore, the central area 31A of the foam 31 corresponds to the flat area of ​​the cover plate 10, and the edge area 31B of the foam 31 corresponds to the curved edge area of ​​the cover plate 10. At this time, the first foam 311 with high density is arranged in the central area 31A, and the second foam 312 with low density is arranged in the edge area 31B, so that the edge area of ​​the curved edge of the cover plate 10 has better buffering performance, and the flat area of ​​the cover plate 10 has better supporting performance, reducing the risk of the curved screen being broken by external force impact, and improving the anti-extrusion and anti-impact capabilities of the curved screen.

[0063] Specifically, the central area 31A and the edge area 31B of the foam 31 are integrally formed.

[0064] The foam 31 needs to play a shading role. If the foam 31 is spliced ​​in blocks, light leakage will occur, and the display module 100 may also cause the splicing gap of the foam 31 to become larger during the subsequent installation process. Therefore, the central area 31A and the edge area 31B of the foam 31 are integrally formed to play a shading role.

[0065] For further information, please refer to Figure 1 The support assembly 30 further includes an adhesive layer 32, a polyimide layer 33 and a metal layer 34; the adhesive layer 32 is disposed between the first side of the foam 31 and the display panel 20, and the polyimide layer 33 is disposed between the second side of the foam 31 and the metal layer 34. The polyimide layer (PI) can play a reinforcing role and increase the reliability of the support assembly 30. The material of the metal layer 34 can be a metal selected from copper and aluminum or an alloy structure thereof, and the metal layer 34 plays a heat dissipation role.

[0066] Furthermore, an optical adhesive (not shown in the figure) is disposed between the cover plate 10 and the display panel 20 to fix the cover plate 10 and the display panel 20 together.

[0067] The optical adhesive is colorless and transparent, has good bonding strength, can be cured at room temperature or medium temperature, and has small curing shrinkage. It should be noted that other adhesive layers with good performance can also be provided to connect the cover plate 10 and the display panel 20, and no specific limitation is made here.

Figure 6 FIG. 2 shows a display device provided by an embodiment of the present invention. Figure 6As shown, the display device 1000 includes the display module 100 as described above.
