Abstract

This application discloses a display module and an electronic device, belonging to the technical field of electronic devices. The display module includes: a substrate, a polarizing layer, a spacer layer, a filler layer, and a frame layer. The polarizing layer and the spacer layer are disposed side by side on the substrate; the filler layer is disposed on the polarizing layer; the frame layer is at least partially disposed on the spacer layer, and the spacer layer and the polarizing layer are integrally formed. Because the frame layer contains large-particle support and dry particles, the spacer layer on the substrate prevents the frame layer from crushing the components on the substrate.

Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and in particular relates to a display module and an electronic device. Background Technology

[0002] OLED is a display lighting technology that has gradually developed in recent years. Especially in the display industry, it is considered to have broad application prospects due to its advantages such as high response, high contrast, and flexibility. Narrow bezels are currently a development trend in the display industry, but achieving narrow bezels for OLED devices is quite difficult. The main reasons include the need for a certain coverage area in the encapsulation structure to effectively protect the device; the GOA circuits are located on both sides of the device, occupying a large space, especially when using oxide TFTs, where several GOA circuits can occupy tens of millimeters. Currently, large-size OLED top-emitting devices are mostly packaged using a Dam & Fill method. The Dam adhesive often contains support space and drying particles, which cannot be placed on the GOA TFT to prevent pressure damage, resulting in a large bezel formed by the Dam.

The frame layer can be placed on top of the spacer layer to prevent it from crushing the components on the substrate. Simultaneously, due to the function of the spacer layer, the frame layer can be positioned as far inward as possible into the substrate, thereby minimizing the bezel width and thus reducing the size of the display module.

[0034] OLED is a display lighting technology that has gradually developed in recent years. Especially in the display industry, it is considered to have broad application prospects due to its advantages such as high response, high contrast, and flexibility. Narrow bezels are currently a development trend in the display industry, but achieving narrow bezels for OLED devices is quite difficult. The main reasons include the need for a certain coverage area in the encapsulation structure to effectively protect the device; the GOA circuits are located on both sides of the device, occupying a large space, especially when using oxide TFTs, where several GOA circuits can occupy tens of millimeters. Currently, large-size OLED top-emitting devices are mostly packaged using a Dam & Fill method. The Dam adhesive often contains support space and drying particles, which cannot be placed on the GOA TFT to prevent pressure damage, resulting in a large bezel formed by the Dam. The display module provided in this application embodiment can improve the above problems. The display module provided in this application embodiment can minimize the width of the bezel, thereby reducing the size of the display module.

[0035] This application is described below with reference to the accompanying drawings and specific embodiments:

[0036] Please see Figure 1 This application provides a display module 10, which can minimize the width of the border, thereby reducing the size of the display module 10.

[0037] In this embodiment, the display module 10 includes: a substrate 11, a polarizing layer 12, a spacer layer 13, a filling layer 14, and a frame layer 15. The polarizing layer 12 and the spacer layer 13 are disposed side by side on the substrate 11; the filling layer 14 is disposed on the polarizing layer 12; the frame layer 15 is at least partially disposed on the spacer layer 13, and the spacer layer 13 and the polarizing layer 12 are integrally formed.

[0038] The frame layer 15 has a higher viscosity and relatively lower fluidity, while the filler layer 14 has a lower viscosity and higher fluidity. During the encapsulation process, the frame layer 15 first defines the encapsulation area on the outside of the substrate 11, and then the filler layer 14 is filled into this area to encapsulate the components on the substrate 11. Because the frame layer 15 contains large-particle support and dry particles, and a spacer layer 13 is provided on the substrate 11, the frame layer 15 can be placed on the spacer layer 13 to prevent it from crushing the components on the substrate 11. Simultaneously, due to the function of the spacer layer 13, the frame layer 15 can be positioned as far inward as possible into the substrate 11, thereby minimizing the width of the bezel and reducing the size of the display module 10.

[0039] Specifically, the frame layer 15 can be Dam glue, and the filler layer 14 can be Filler glue.

[0040] The component can be a TFT11a. The TFT11a is disposed on the substrate 11, and a thin film encapsulation layer 11b is disposed to encapsulate the TFT11a on the substrate 11.

[0041] The substrate 11 can be roughly divided into two areas: a display area and a non-display area. Within the display area, a pixel defining layer 11c is disposed between the thin-film encapsulation layer 11b and the TFT 11a. In related technologies, because the frame layer 15 has certain support and drying particles, the frame layer 15 can only overlap the wiring position in the non-display area, that is, it can only be placed on the circuit in the GOA area. If it extends inward, it will damage the components on the substrate 11. However, in this embodiment, because the spacer layer 13 is provided to isolate and support the frame layer 15, the frame layer 15 can extend further inward, minimizing the width of the bezel and thus reducing the size of the display module 10.

[0042] In this embodiment, the spacer layer 13 and the polarizing layer 12 are integrally formed, that is, the spacer layer 13 and the polarizing layer 12 are manufactured together. This protects the components on the substrate 11 without adding new processes, and reduces the width of the frame without adding processes, thus not increasing manufacturing costs.

[0043] In this embodiment, the material of the spacer layer 13 is the same as that of the polarizing layer 12. The fact that they are made of the same material indicates that the spacer layer 13 and the polarizing layer 12 are made of the same material, and the polarizing layer 12 also plays a certain role. The frame layer 15 can diffuse as far inward as possible into the substrate 11. Even if it is mounted above the TFT 11a, since the polarizing layer 12 also has an isolating function, the frame layer 15 will not damage the TFT 11a below. The frame layer 15 can be disposed as far inward as possible into the substrate 11, minimizing the width of the frame.

[0044] The display module 10 also includes a cover plate 16, which is pressed onto the frame layer 15 and the filling layer 14.

[0045] The material of the spacer layer 13 is the same as that of the polarizing layer 12, and the two are integrally formed. During the manufacturing process, the molding process of the spacer layer 13 and the polarizing layer 12 can be reduced, and the width of the frame can be reduced without increasing the number of processes and without increasing the manufacturing cost.

[0046] The material of the spacer layer 13 is the same as that of the polarizing layer 12, and the two are integrally formed. Making them together can minimize the possibility of uneven film formation in the polarizing layer 12 during the manufacturing process.

[0047] The spacer layer 13 and the polarizing layer 12 are high refractive index photoresist adhesives with a refractive index of 1.5 to 1.7. The materials include, but are not limited to, monomers or mixtures of epoxy resin, vinyl acetate, aldehydes, acrylates, and isocyanates.

[0048] In this embodiment, the spacer layer 13 includes a plurality of support units 13a, and the spacing between two adjacent support units 13a is a first spacing. The polarizing layer 12 includes a plurality of polarizing units 12a, and the spacing between two adjacent polarizing units 12a is a second spacing. The first spacing is less than or equal to the second spacing.

[0049] The polarizing layer 12 requires optical design, and the spacing between multiple polarizing units 12a should not be too large. Similarly, the support unit 13a needs to act as a spacer, and its spacing should not be too large either. If the spacing between the support units 13a is too large, it can easily cause large particle structures to damage the components on the substrate 11 at the spacing position.

[0050] The first spacing can be less than or equal to the second spacing, meaning the first spacing can be equal to the second spacing, which can further reduce the manufacturing steps of the spacer layer 13 and the polarizing layer 12 without increasing manufacturing costs. Of course, the first spacing can be slightly smaller than the second spacing.

[0051] In this embodiment, the first spacing is 2.5um-4um, and the second spacing is 2.5um-5um.

[0052] If the first spacing is too large, large particles in the frame layer 15 will damage the components on the substrate 11 by pressing them into the gap of the support unit 13a. On the other hand, if the first spacing is too small, the support in the frame layer 15 will not work properly. Therefore, the first spacing of 2.5um-4um can ensure that the frame layer 15 will not damage the TFT 11a on the substrate 11, and also enable the frame layer 15 to work properly.

[0053] Similarly, the second spacing mainly serves to polarize light. If the second spacing is too small or too large, the light source cannot pass through the polarizing layer 12, affecting the effect of the display module 10. Setting the second spacing between 2.5um and 5um can ensure that the display module 10 can emit light normally.

[0054] Furthermore, a first spacing of 2.5um-4um indicates that the first spacing is greater than or equal to 2.5um and less than or equal to 4um. Similarly, a second spacing of 2.5um-5um indicates that the second spacing is greater than or equal to 2.5um and less than or equal to 5um.

[0055] In this embodiment, the height of the support unit 13a is greater than or equal to the height of the polarizing unit 12a. The support unit 13a mainly serves a supporting function, and its height can be set relatively large to provide some support for the frame layer 15 in the direction of polarization, thus preventing the frame layer 15 from damaging the components below.

[0056] The support unit 13a mainly serves a supporting function. The frame layer 15 contains large particles, which may cause slight deformation of the support unit 13a when pressed on top of it. The height of the support unit 13a can be slightly higher than the height of the polarizing unit 12a.

[0057] The height of the support unit 13a is 3um-12um, and the height of the polarizing unit 12a is 3um-10um.

[0058] The support unit 13a mainly serves a supporting function. The frame layer 15 overlaps on top of the support unit 13a. If the height of the support unit 13a is too low, the frame layer 15 may still damage the components on the substrate 11 due to its large weight. If the height is too high, it will increase the thickness of the entire display module 10. The height of the support unit 13a is between 3um and 12um, which can ensure the isolation of the frame layer 15 while minimizing the thickness of the display module 10.

[0059] Similarly, as long as the polarizing unit 12a plays a role in polarizing light, if the height of the polarizing unit 12a is too small or too large, the light source cannot pass through the polarizing layer 12, affecting the effect of the display module 10. Setting the second spacing between 3um and 10um can ensure that the display module 10 can emit light normally.

[0060] Furthermore, a height of 3um-12um for the support unit 13a indicates that the height of the support unit 13a is greater than or equal to 3um and less than or equal to 12um. Similarly, a height of 3um-10um for the polarizing unit 12a indicates that the height of the polarizing unit 12a is greater than or equal to 3um and less than or equal to 10um.

[0061] In this embodiment, the support unit 13a has a first contact surface that contacts the substrate 11 and is circular. The polarizing unit 12a has a second contact surface that contacts the substrate 11 and is circular. The radius of the first contact surface is greater than or equal to the radius of the second contact surface.

[0062] The first contact surface is circular, and the second contact surface is also circular. By making both the first and second contact surfaces circular, the bottoms of the support unit 13a and the polarizing unit 12a can be smoothly transitioned, reducing damage to other components during the packaging process.

[0063] The radius of the first contact surface is greater than or equal to the radius of the second contact surface, indicating that the first contact surface is relatively large. The support unit 13a will bear the large particles in the sealing layer 15. The relatively large first contact surface can improve the stability of the support unit 13a and prevent the large particles in the sealing layer 15 from crushing the components on the substrate 11.

[0064] In this embodiment, the radius of the first contact surface is 3um-20um, and the radius of the second contact surface is 3um-10um.

[0065] If the radius of the first contact surface is too large, it may result in a large individual support unit 13a. If the radius of the first contact surface is too small, it may not be able to support the large particles in the middle sealing layer 15. Setting the radius of the first contact surface to 3µm-20µm can support the sealing layer 15 while...

[0066] The radius of the first contact surface is 3um-20um, meaning the radius of the first contact surface is greater than or equal to 3um and less than or equal to 20um. Similarly, the radius of the second contact surface is 3um-10um, meaning the radius of the second contact surface is greater than or equal to 3um and less than or equal to 10um.

[0067] In this embodiment, the polarizing unit 12a is a hemispherical or quarter-spherical structure, and the supporting unit 13a is one of a hemispherical, quarter-spherical, or semi-cylindrical structure.

[0068] Please see Figure 2In this embodiment, the support units 13a can have the same size, that is, multiple support units 13a can be arranged in a matrix. Of course, in other embodiments, the support units 13a can have different sizes. For example, the support unit 13a includes a first support unit 13b and a second support unit 13c. The radius of the first contact surface of the first support unit 13b is smaller than the radius of the second support surface. The first support unit 13b and the second support unit 13c are alternately arranged.

[0069] Multiple first support units 13b form a row, and multiple second support units 13c form a row, with a row of first support units 13b and a row of second support units 13c being alternately arranged.

[0070] The first support unit 13b and the second support unit 13c have different radii. The two support units 13a with different radii can provide different support forces, which can support the frame layer 15 as much as possible and reduce the damage of the components on the substrate 11 caused by the frame layer 15.

[0071] In this embodiment, the height of the first support unit 13b is the same as the height of the second support unit 13c. This allows the first support unit 13b and the second support unit 13c to contact large particles in the frame layer 15 at the same height, reducing the contact between the frame layer 15 and the components.

[0072] Please see Figure 3 In addition, in other embodiments, the support unit 13a includes a first support unit 13b, a second support unit 13c, and a third support unit 13d, and the radii of the first contact surfaces of the first support unit 13b, the second support unit 13c, and the third support unit 13d are all different.

[0073] The support unit 13a is configured as a first support unit 13b, a second support unit 13c, and a third support unit 13d with three different radii. These three units can be grouped together, and multiple unit groups can be arranged side-by-side sequentially. Within a unit group, taking an example where the radius of the first support unit 13b is larger than that of the second support unit 13c, and the radius of the second support unit 13c is larger than that of the third support unit 13d, the first support unit 13b can be placed in the middle, with the second support unit 13c and the third support unit 13d placed on either side. Alternatively, they can be arranged in the order of first support unit 13b, second support unit 13c, and third support unit 13d. Another option is to place the third support unit 13d in the middle, with the first support unit 13b and the second support unit 13c placed on either side of it.

[0074] In this embodiment, the first support unit 13b, the second support unit 13c, and the third support unit 13d have the same height. This allows the first support unit 13b, the second support unit 13c, and the third support unit 13d to contact large particles in the frame layer 15 at the same height, reducing the contact between the frame layer 15 and the components.

[0075] In addition, the first contact surface of the first support unit 13b, the first contact surface of the second support unit 13c, and the first contact surface of the third support unit 13d are not limited to circular shapes. In order to cover the TFT below, the first contact surface can be set with different shapes according to the different shapes of the TFT 11a. The first contact surface can also be rectangular or other shapes.

[0076] For example, the first real-time method can be: the polarizing unit 12a is a hemispherical structure with a height of 4um and a diameter of 10um for the second contact surface, the spacing between two adjacent polarizing units 12a is 2.5um, and the parameters of the support unit 13a are the same as those of the polarizing unit 12a.

[0077] The second implementation: the polarizing unit 12a is a hemispherical structure with a height of 4um and a diameter of 10um for the second contact surface, and the distance between two adjacent polarizing units 12a is 2.5um. The support unit 13a is a hemispherical structure with a height of 8um and a diameter of 20um for the first contact surface, and the distance between two adjacent support units 13a is 2.5um.

[0078] The third implementation method: such as Figure 2 As shown, the polarizing unit 12a is a hemispherical structure with a height of 4 μm and a diameter of 10 μm for the second contact surface, with a spacing of 2.5 μm. The first support unit 13b is a hemispherical structure with a height of 8 μm and a diameter of 10 μm for the first contact surface. The second support unit 13c is a hemispherical structure with a height of 8 μm and a diameter of 20 μm for the first contact surface. The first support unit 13b and the second support unit 13c are placed alternately with a spacing of 2.5 μm.

[0079] The fourth implementation method: such as Figure 3As shown, the polarizing unit 12a is a hemispherical structure with a height of 4 μm and a second contact surface diameter of 10 μm, with a spacing of 2.5 μm. In the spacer layer 13, the arrangement can be configured according to the arrangement of the TFTs 11a on the substrate 11 below. The first support unit 13b is a hemispherical or semi-cylindrical structure with a height of 8 μm and a first contact surface diameter of 10 μm; the second support unit 13c is a hemispherical or semi-cylindrical structure with a height of 8 μm and a first contact surface diameter of 20 μm; and the third support unit 13d is a hemispherical or semi-cylindrical structure with a height of 8 μm and a first contact surface diameter of 10 μm. The spacing is not less than 2.5 μm. The positions of the first support unit 13b, the second support unit 13c, and the third support unit 13d can be arranged according to the position of the TFTs 11a below, ensuring that they cover the TFTs 11a below. Alternatively, any one of the first contact surfaces of the first support unit 13b, the second support unit 13c, and the third support unit 13d can be set to other shapes to facilitate covering the components below.

[0080] In summary, the display module 10 provided in this application embodiment has a frame layer 15 with higher viscosity and relatively lower fluidity, while the filler layer 14 has lower viscosity and higher fluidity. During the encapsulation process, the frame layer 15 first defines the encapsulation area on the outside of the substrate 11, and then the filler layer 14 is filled within this area to encapsulate the components on the substrate 11. Because the frame layer 15 contains large-particle support and dry particles, and a spacer layer 13 is provided on the substrate 11, the frame layer 15 can be placed on the spacer layer 13 to prevent it from crushing the components on the substrate 11. Simultaneously, due to the function of the spacer layer 13, the frame layer 15 can be positioned as far inward as possible into the substrate 11, thereby minimizing the width of the bezel and reducing the size of the display module 10.
