[0004] However, the diffusion layer in current display modules is prone to generating bubbles, and these bubbles can easily enter the display area of the display module, resulting in poor display performance. Utility Model Content

[0007] The display panel includes: a first panel portion and a second panel portion disposed opposite to each other, and a panel bending portion for connecting the first panel portion and the second panel portion;
[0008] The polarizer is located on the display side of the display panel, which is the side of the first panel portion that faces away from the second panel portion;

In this case, even if the diffusion layer is thin, because the polarizer and the protective colloid will not contact each other, and the protective colloid will not exceed the surface of the polarizer, no air bubbles will be generated after the diffusion layer and the polarizer are bonded together, resulting in a better display effect for the display module.

[0034] Figure 6 This is a schematic diagram of the film layer structure of another display module provided in the embodiments of this application. Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0036] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the film layer structure of a display module. The display module 00 includes: a display panel 01, a polarizer 02, a diffusion layer 03, a protective cover plate 04, and a protective colloid 05.
[0037] The display panel 01 in the display module 00 includes: a first panel portion 11 and a second panel portion 21 disposed opposite to each other, and a panel bending portion 31 for connecting the first panel portion 11 and the second panel portion 21. That is, the panel bending portion 31 can be located between the first panel portion 11 and the second panel portion 21, and one side of the panel bending portion 31 can be connected to the first panel portion 11, and the other side of the panel bending portion 31 can be connected to the second panel portion 21.
[0038] The polarizer 02 in the display module 00 is located on the display side of the display panel 01 and is used to reduce the reflectivity of the display panel 01 to ambient light, so as to ensure that the display area within the display panel 01 displays a better image.
[0039] The diffusion layer 03 is located on the side of the polarizer 02 away from the display panel 01. It is used to evenly disperse the light emitted from the display panel 01, eliminate the unevenness of the light, and prevent bright spots from appearing in the display area of the protective cover plate 04 with the anti-glare structure etched on it.
[0040] The protective cover 04 is located on the side of the diffusion layer 03 opposite to the display panel 01. Since the protective cover 04 has an anti-glare structure etched on the side opposite to the display panel 01, it can be used to prevent external ambient light from being reflected on the side of the protective cover 04 opposite to the display panel 01, so as to ensure that the display area of the display module 00 displays a better picture.
[0041] The protective colloid 05 is located on the panel bending portion 130, and the protective colloid 05 is also located on the first panel portion 11 and the edge portion near the panel bending portion 31. In this way, when the side of the display device equipped with the display module 000 is impacted, the protective colloid 05 can protect the side of the panel bending portion 31 away from the first panel portion 11.
[0042] During the application of protective colloid 05 to the first panel 11, due to the siphon effect, the protective colloid 05 extends beyond the surface of the polarizer 02. After removing the protective film from the side of the polarizer 02 facing away from the display panel 01, protrusions form at the edges where the protective colloid 05 separates from the polarizer 02. If the diffusion layer 03 is thin, it cannot fill the gaps formed by these protrusions, resulting in air bubbles in the area where the protective colloid 05 extends beyond the surface of the polarizer 02, leading to poor display performance of the display module 00.
[0043] Please refer to Figure 2 , Figure 2This is a schematic diagram of the film layer structure of a display module provided in an embodiment of this application. The display module 000 may include: a display panel 100, a polarizer 200, a diffusion layer 300, a protective cover plate 400, and a protective colloid 500.
[0044] The display panel in the display module 000 includes a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. That is, the panel bending portion 130 can be located between the first panel portion 110 and the second panel portion 120, and one side of the panel bending portion 130 can be connected to the first panel portion 110, and the other side of the panel bending portion 130 can be connected to the second panel portion 120.
[0045] The polarizer 200 in the display module 000 is located on the display side of the display panel 100. Here, the display side of the display panel 100 is the side of the first panel portion 110 that faces away from the second panel portion 120, and this display side is the side of the display panel 100 used for displaying images. The polarizer 200 can be bonded to the display side of the display panel 100. The polarizer 200 can reduce the reflectivity of the display panel 100 to ambient light, thereby ensuring better image quality in the display area within the display panel 100.
[0046] The diffusion layer 300 in the display module 000 is located on the side of the polarizer 200 away from the display panel 100, and is used to evenly disperse the light emitted from the display panel 01 to eliminate light inhomogeneity.
[0047] The protective cover plate 400 in the display module 000 is located on the side of the diffusion layer 300 away from the display panel 100, and is used to protect the display side of the display panel 100.
[0048] The protective colloid 500 in the display module 000 includes at least a first colloid portion 510 and a second colloid portion 520 connected to each other. The first colloid portion 510 is located on the panel bending portion 130, and the second colloid portion 520 is located on the first panel portion 110. Thus, when the side of the display device equipped with the display module 000 is impacted, the protective colloid 500 can protect the side of the panel bending portion 130 facing away from the first panel portion 110. It should be noted that the protective colloid 500 may further include a third colloid portion 530 connected to the first colloid portion 510. The third colloid portion 530 is located on the side of the second panel portion 120 facing away from the first panel portion 110.
[0049] In the first direction x, a first gap K1 exists between the second colloid portion 520 of the protective colloid 500 and the polarizer 200. For example, the width of the first gap K1 can be 0.2 mm. Here, the first direction x is parallel to the first panel portion 110 and perpendicular to the bending axis of the panel bending portion 130. That is, by retracting the second colloid portion 520 towards the polarizer 200, the polarizer 200 and the second colloid portion 520 will not contact each other. Therefore, during the application of the protective colloid 500 to the first panel portion 110, the protective colloid 500 will not exceed the surface of the polarizer 200 due to a siphon effect. In this case, even if the thickness of the diffusion layer 300 is small, because the polarizer 200 and the protective colloid 500 will not contact each other, and the protective colloid 500 will not exceed the surface of the polarizer 200, no air bubbles will be generated after the diffusion layer 300 and the polarizer 200 are bonded together, resulting in a better display effect for the display module 000.
[0050] In summary, the display module provided in this application embodiment has a first gap between the second colloid portion in the protective colloid and the polarizer. That is, by retracting the second colloid portion towards the polarizer, the polarizer and the second colloid portion will not contact each other. Therefore, during the coating of the protective colloid onto the first panel, the protective colloid will not exceed the surface of the polarizer due to a siphon effect. In this case, even if the diffusion layer is thin, because the polarizer and the protective colloid will not contact each other, and the protective colloid will not exceed the surface of the polarizer, no air bubbles will be generated after the diffusion layer and the polarizer are bonded together, resulting in a better display effect for the display module.
[0051] Please refer to the following during the implementation of this application: Figure 3 , Figure 3 This is a schematic diagram of the film layer structure of another display module provided in this application embodiment. The display module 000 may further include: a plurality of functional film layers 600 located on the side of the first panel portion 110 facing the second panel portion 120. The plurality of functional film layers 600 may include a first support layer, a mesh adhesive layer, a foam layer, a polyimide film layer, and a copper foil stacked in a direction away from the first panel portion.
[0052] The first support layer in the display module 000 can be bonded to the side of the first panel portion 110 facing the second panel portion 120. The first support layer in the display module 000 can be used to support the first panel portion 110. A mesh adhesive layer can be located on the side of the first support layer opposite to the first panel portion, and this mesh adhesive layer can be bonded to the side of the first support layer opposite to the first panel portion. Here, the side of the mesh adhesive layer opposite to the first support layer can be bonded to the side of the foam layer facing the first panel portion. The side of the foam layer opposite to the first panel portion 110 can be bonded to the polyimide film layer. The side of the polyimide film layer opposite to the first panel portion 110 can be bonded to the copper foil.
[0053] It should be noted that the display module 000 may further include: a support pillar 700 and a second support layer 800 located between the plurality of functional film layers 600 and the second panel portion 120. The second support layer 800 is closer to the second panel portion 120 than the support pillar 700. The second support layer 800 can be used to support the second panel portion 120; the support pillar 700 can be used to bond the plurality of functional film layers 600 and the second support layer 800, and to support the plurality of functional film layers 600 and the second support layer 800.
[0054] In some implementations, such as Figure 3 As shown, the display module 000 may further include a light-shielding ink layer 900. The light-shielding ink layer 900 is located on the side of the protective cover plate 400 facing the display panel 100, and covers the edge portion of the protective cover plate 400. The light-shielding ink layer 900 can be used to form the bezel of the display module 000, shielding the driving circuits and connecting traces within the display module 000, thereby achieving an aesthetic purpose.
[0055] In this configuration, the edge portion of the protective cover 400 covered by the light-shielding ink layer 900 is opaque. Therefore, the protective cover 400 has a central light-transmitting area 410 and a light-shielding area 420 surrounding the central light-transmitting area 410. It should be noted that the display panel 100 has a display area S1 and a non-display area S2 surrounding the display area S1. The central light-transmitting area 410 of the protective cover 400 covers the display area S1, allowing light emitted from the display area S1 of the display panel 100 to pass through the central light-transmitting area 410 of the protective cover 400 and exit, enabling the display module 000 to display images normally.
[0056] The polarizer 200's orthogonal projection onto the protective cover 400 covers the central light-transmitting area 410. That is, in the first direction x, the orthogonal projection of the edge portion of the polarizer 200 towards the panel bend 130 onto the protective cover 400 lies within the light-shielding area 420. In this way, the metal traces located in the non-display area S2 of the display panel 100, especially those exposed through the first gap K1, can be effectively shielded by the light-shielding ink layer 900, thus achieving an aesthetic purpose.
[0057] In this case, please refer to Figure 3 and Figure 4 , Figure 4 This is a bottom view of a display module provided in an embodiment of this application. It should be noted that... Figure 3 It can be Figure 4The diagram shows the film structure of the display module at point A-A'. The protective cover 400 may include a main body portion 400a and a first protruding portion 400b connected to each other. The main body portion 400a covers at least a portion of the first panel portion 110, and the first protruding portion 400b covers the panel bend portion 130. Here, the central light-transmitting area 410 is located within the main body portion 400a, and a portion of the light-shielding area 420 is located within the first protruding portion 400b.
[0058] In the first direction x, the distance D1 between the side of the polarizer 200 facing the panel bending portion 130 and the side of the first protrusion 400b away from the main body portion 400a is greater than the distance D2 between the side of the second colloid portion 520 away from the first colloid portion 510 and the side of the first protrusion 400b away from the main body portion 400a.
[0059] This effectively ensures that a first gap K1 exists between the second colloid portion 520 in the protective colloid 500 and the polarizer 200. That is, by retracting the side of the second colloid portion 520 closest to the polarizer 200, the polarizer 200 and the second colloid portion 520 will not come into contact. Therefore, during the application of the protective colloid 500 to the first panel portion 110, the protective colloid 500 will not exceed the surface of the polarizer 200 due to a siphon effect. In this case, even if the thickness of the diffusion layer 300 is small, because the polarizer 200 and the protective colloid 500 will not come into contact, and the protective colloid 500 will not exceed the surface of the polarizer 200, no air bubbles will be generated after the diffusion layer 300 and the polarizer 200 are bonded together, resulting in a better display effect for the display module 000.
[0060] It should be noted that, due to the first gap K1 between the second colloid portion 520 and the polarizer 200, that is, the side of the second colloid portion 520 closest to the polarizer 200 is recessed. Therefore, to prevent the protective colloid 500 from detaching from the display panel 100, the thickness of the protective colloid 500 is increased to make the protective colloid 500 adhere more firmly to the display panel 100. For example, the thickness of the protective colloid 500 is greater than or equal to 0.1 mm.
[0061] For some implementation methods, please refer to Figure 5 , Figure 5 yes Figure 4 The diagram shows the film structure of the display module at B-B'. The protective cover 400 may further include a second protruding portion 400c connected to the main body portion 400a and the first protruding portion 400b. Here, a portion of the light-shielding area 420 is located within the first protruding portion 400b, and another portion is located within the second protruding portion 400c.
[0062] It should be noted that the display panel 000 is typically a rectangular display panel, which has a top bezel, a left bezel, a right bezel, and a bottom bezel. The first protrusion in the protective cover 400 is located inside the bottom bezel, and the second protrusion is located inside the left bezel, the right bezel, and the top bezel.
[0063] In some implementations, the protective cover 400 in the display module 000 has an anti-glare structure on the side facing away from the display panel 100. The anti-glare structure on the protective cover 400 can be multiple uneven dots formed by etching, making the side of the protective cover 400 facing away from the display panel 100 a rough plane. This can prevent external ambient light from being reflected on the side of the protective cover 400 facing away from the display panel 100, thus preventing the formation of polarized light. This effectively improves the clarity and comfort of the display module 000, ensuring that the image displayed in the display area of the display module 000 has a better effect.
[0064] It should be noted that, in other possible implementations, an anti-glare film can be formed on the side of the protective cover 400 opposite to the display panel 100 to prevent external ambient light from being reflected and forming polarized light on the side of the protective cover 400 opposite to the display panel 100, thereby improving the display effect of the image displayed in the display area of the display module 000. This application does not limit this aspect.
[0065] It should also be noted that when the protective cover plate 400 in the display module 000 has an anti-glare structure on the side facing away from the display panel 100, the diffusion layer 300 can evenly disperse the light emitted from the display area S1 of the display panel 100, eliminating the unevenness of light. This can effectively prevent bright spots from appearing in the central light-transmitting area 410 of the protective cover plate 400 with the etched anti-glare layer, thus ensuring that the display area of the display module 000 displays a better picture.
[0066] Here, in the first direction x, a second gap K2 exists between the second colloidal portion 520 of the protective colloid 500 and the diffusion layer 300. The width of the second gap K2 is less than or equal to the width of the first gap K1. In this case, the orthographic projection of the polarizer 200 onto the protective cover plate 400 lies within the orthographic projection of the diffusion layer 300 onto the protective cover plate 400, or the orthographic projection of the polarizer 200 onto the protective cover plate 400 overlaps with the orthographic projection of the diffusion layer 300 onto the protective cover plate 400.
[0067] This effectively ensures that the orthographic projection of the diffusion layer 300 on the protective cover plate 400 covers the orthographic projection of the display area S1 of the display panel 100 on the protective cover plate 400, and also covers the central light-transmitting area 410 of the protective cover plate 400. This ensures that the diffusion layer 300 can evenly disperse the light emitted from the display area S1 of the display panel 100, eliminating light unevenness. Consequently, it effectively prevents bright spots from appearing in the central light-transmitting area 410 of the protective cover plate 400, which has an etched anti-glare layer, thus ensuring a better image quality displayed in the display area of the display module 000.
[0068] In some implementations, such as Figure 3 As shown, the display module 000 may further include an optical adhesive layer 1000 located between the diffusion layer 300 and the protective cover plate 400. Here, the two sides of the optical adhesive layer 1000 are bonded to the diffusion layer 300 and the protective cover plate 400 respectively, to achieve adhesion between the protective cover plate 400 and the diffusion layer 300. The optical adhesive layer 1000 is typically made of a transparent adhesive (e.g., acrylic adhesive). This ensures that light emitted from the display panel 100 passes through the optical adhesive layer 1000 and the protective cover plate 400 before exiting. Furthermore, since the thickness of the optical adhesive layer 1000 is greater than the thickness of the diffusion layer 300, the optical adhesive layer 1000 also has better cushioning properties. Thus, when the front of the display module 000 is subjected to an impact force, the cushioning effect of the optical adhesive layer 1000 can effectively reduce the probability of the protective cover plate 400 being broken. For example, the thickness of the diffusion layer 300 can be 0.04 mm.
[0069] Alternatively, in other embodiments, please refer to Figure 6 , Figure 6 This is a schematic diagram of the film layer structure of another display module provided in this application embodiment. The diffusion layer 300 in the display module 000 and the optical adhesive layer in the display module 000 can be reused as the same film layer. In this case, the diffusion layer 300 in the display module 000 has a large thickness, which allows the diffusion layer 300 to evenly disperse the light emitted from the display area S1 of the display panel 100. At the same time, the diffusion layer 300 also has good buffering properties. Thus, when the front of the display module 000 is subjected to an impact force, the buffering effect of the diffusion layer 300 can effectively reduce the probability of the protective cover 400 being broken.
[0070] It should be noted that the diffusion layer 300 in the display module 000 has multiple possible configurations. This application embodiment uses the following two possible configurations as examples for illustrative explanation.
[0071] In the first possible scenario, the diffusion layer 300 in the display module 000 may include a colloid and diffusion particles mixed within the colloid. When light emitted from the display area S1 of the display panel 100 enters the diffusion layer 300, the light illuminating the diffusion particles in the diffusion layer 300 undergoes refraction, reflection, and scattering, thereby changing the direction of light propagation, dispersing the light evenly, eliminating light non-uniformity, and preventing bright spots or dark areas from appearing on the display screen.
[0072] In a second possible scenario, the diffusion layer 300 in the display module 000 may include an colloid and a diffusion film located on one side of the colloid. The diffusion film is closer to the protective cover plate than the colloid. In this case, the display module 000 includes an optical adhesive layer 1000 located between the diffusion layer 300 and the protective cover plate 400. Thus, the optical adhesive layer 1000 can be used to bond the protective cover plate 400 to the diffusion film, and the colloid in the diffusion layer 300 can be used to bond the diffusion film to the polarizer 200. The diffusion film in the diffusion layer 300 can adjust the light emitted from the display area S1 of the display panel 100, making the light emitted from the diffusion layer 300 more uniform. The colloid in the diffusion layer 300 can be made of a transparent adhesive (e.g., acrylic adhesive). This ensures that the light emitted from the display panel 100 passes through the colloid in the diffusion layer 300.
[0073] In summary, the display module provided in this application embodiment has a first gap between the second colloid portion in the protective colloid and the polarizer. That is, by retracting the second colloid portion towards the polarizer, the polarizer and the second colloid portion will not contact each other. Therefore, during the coating of the protective colloid onto the first panel, the protective colloid will not exceed the surface of the polarizer due to a siphon effect. In this case, even if the diffusion layer is thin, because the polarizer and the protective colloid will not contact each other, and the protective colloid will not exceed the surface of the polarizer, no air bubbles will be generated after the diffusion layer and the polarizer are bonded together, resulting in a better display effect for the display module.
[0074] This application embodiment also provides a display device, which may include: a frame, and a display module connected to the frame, wherein the display module is... Figures 2 to 6 The display module 000 shown can be any product or component with a display function, such as electronic paper, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.
[0075] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element.
