Description

Technical Field

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

[0002] With the development of Organic Light-Emitting Diode (OLED) technology, OLED panels are widely used in screen display applications. To improve display brightness, a microlens panel (MLP) solution is used in related technologies, which allows the light emitted from the OLED panel's light-emitting layer to be reflected directly at the lens interface, thereby achieving light focusing. However, the light reflection effect in these technologies is relatively poor, resulting in only a small improvement in luminous efficacy. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a display panel and an electronic device.

[0004] According to a first aspect of the present disclosure, a display panel is provided, comprising:

[0005] Emissive layer;

[0006] A cover layer covers the light-emitting side of the light-emitting layer. The cover layer includes a first layer and a second layer stacked together. The second layer is located between the first layer and the light-emitting layer. The refractive index of the second layer is less than that of the first layer.

[0007] The second layer includes a protrusion having a first side, a second side, and a third side. The first side faces the light-emitting side of the light-emitting layer, the second side faces away from the light-emitting side of the light-emitting layer, and the third side is connected to the first side and the second side. The third side is used to reflect the scattered light from the light-emitting layer out of the second layer on the side facing away from the light-emitting layer. The third side is concave.

[0008] In some embodiments, the first layer is made of a film material.

[0009] In some embodiments, the refractive index of the first layer is greater than or equal to 1.67.

[0010] In some embodiments, the light-emitting layer has a plurality of sub-pixel regions arranged in an array;

[0011] The sub-pixel region is located on the light-emitting side of the light-emitting layer, and the protrusion is offset from the sub-pixel region.

[0012] In some embodiments, the protrusions are provided in multiple forms;

[0013] Multiple of the aforementioned protrusions are arranged in an array; and / or,

[0014] The protrusions are elongated, and the length directions of each protrusion are parallel to each other.

[0015] In some embodiments, the cover layer has multiple layers.

[0016] In some embodiments, the protrusions included in the second layer of any two adjacent cover layers of the multilayer cover layer are misaligned.

[0017] In some embodiments, the protrusion is elongated;

[0018] In any two adjacent layers of a multi-layered covering, the protrusions in the second layer are parallel to each other in their length direction or have a predetermined angle.

[0019] In some embodiments, the preset angle is 90°.

[0020] According to a second aspect of the present disclosure, an electronic device is provided, comprising:

[0021] The display panel described in any of the first aspects above.

[0022] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: A light-emitting layer emits light based on a control signal to achieve image display, and a cover layer covers the light-emitting side of the display image on the light-emitting layer. The first and second layers are bonded together, and by providing protrusions, the protrusions can refract and reflect the scattered light from the light-emitting layer. When the scattered light from the light-emitting layer passes through the contact area between the first and second layers, i.e., the second and third sides of the protrusions, it undergoes refraction. After refraction, the light converges towards the center, achieving a focusing effect to improve brightness in the user's viewing direction. Simultaneously, some of the scattered light from the light-emitting layer is reflected when it passes through the third side of the protrusions. By setting the third side as a concave surface, the ability to converge scattered light can be effectively improved, thereby increasing the brightness of the display panel in the user's viewing direction.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] With the development of Organic Light-Emitting Diode (OLED) technology, OLED panels are widely used in screen display applications. A key technology employs a microlens pan (MLP) approach. By forming microlens structures within the film layers, light emitted from the OLED panel's light-emitting layer is directly refracted at the microlens interfaces, thus focusing the light. Specifically, in microlens structures formed on low-refractive-index material layers, light emitted from the light-emitting layer passes sequentially through both low-refractive-index and high-refractive-index material layers for refraction. Simultaneously, the sides of the microlens structure can also reflect light. However, in microlens structures formed on low-refractive-index material layers, the sides are all planar, resulting in poor reflection of scattered light and a small improvement in luminous efficacy.

[0039] To address the aforementioned technical problems, this disclosure provides a display panel and an electronic device that improves the brightness of the display panel by setting the side surface of the microlens structure on the low-refractive material layer to a concave surface, thereby enhancing the focusing effect on the reflection of scattered light.

[0040] Figure 1 This is a schematic diagram of the structure of a display panel 100 according to an exemplary embodiment. Figure 2 This is a schematic diagram of the optical path of a display panel 100 according to an exemplary embodiment. Figure 1 and Figure 2 As shown, the display panel 100 in this embodiment includes: a light-emitting layer 20; a cover layer 10 covering the light-emitting side of the light-emitting layer 20; the cover layer 10 includes a first layer 11 and a second layer 12 stacked together, the second layer 12 being located between the first layer 11 and the light-emitting layer 20, and the refractive index of the second layer 12 being less than that of the first layer 11; the second layer 12 includes a protrusion 121, the protrusion 121 having a first side surface 1211, a second side surface 1212, and a third side surface 1213; the first side surface 1211 faces the light-emitting side of the light-emitting layer, the second side surface 1212 faces away from the light-emitting side of the light-emitting layer, and the third side surface 1213 is connected to the first side surface 1211 and the second side surface 1212 respectively, the third side surface 1213 being used to reflect the scattered light from the light-emitting layer out of the second layer 12 facing away from the light-emitting layer 20, and the third side surface 1213 is concave.

[0041] The light-emitting layer 20 emits light based on control signals to achieve image display, and the cover layer 10 covers the light-emitting side of the display image of the light-emitting layer 20. The first layer 11 and the second layer 12 are bonded together, and a protrusion 121 is provided so that the protrusion 121 can refract and reflect the scattered light from the light-emitting layer 20. When the scattered light from the light-emitting layer 20 passes through the contact area between the first layer 11 and the second layer 12, i.e., the second side 1212 and the third side 1213 of the protrusion 121, it is refracted. After refraction, the light converges towards the center, acting as a light-focusing effect to improve the brightness in the user's viewing direction. Simultaneously, some of the scattered light from the light-emitting layer 20 is reflected at the third side 1213 of the protrusion 121. Figure 2 As shown, Figure 2 The arrows in the diagram represent the direction of scattered light when it is reflected at the third side 1213. By making the third side 1213 concave, the ability to converge scattered light can be effectively improved, thereby increasing the brightness of the display panel 100 in the user's viewing direction.

[0042] In some embodiments, the first layer 11 is applied onto the second layer 12 by inkjet printing (IJP). The second layer 12 forms protrusions 121 by organic pattern microstructuring.

[0043] In other embodiments, the second layer 12, which has been pre-processed with organic pattern microstructure to form the protrusions 121, contains acrylic pressure-sensitive adhesive (PSA). To prevent the first layer 11 from fusing with the acrylic PSA, which would reduce the refractive index of the high-refractive-index material layer, cause uneven water stains, and because inkjet printing coating requires a crosslinking rate of 50% or higher, UV light / thermal post-crosslinking is necessary. Since excessively soft and fluid high-refractive-index materials can lead to decreased adhesion and mechanical strength at high temperatures, resulting in reliability issues, the first layer 11 is made of an adhesive film material, allowing it to be bonded to the second layer 12 via lamination.

[0044] In some embodiments, the refractive index of the first layer 11 is greater than or equal to 1.67, further enhancing the focusing effect on scattered light.

[0045] Figure 6 This is a schematic diagram of the refractive indices of various materials. For example... Figure 6As shown, related studies have demonstrated that polymers are superior to inorganic materials due to their mechanical flexibility, lightweight, handleability, dyeability, low cost, and impact resistance. Halogen elements (such as chlorine, bromine, and iodine) with high atomic refractive indices of 5.97 to 13.90 can be useful components for developing high-refractive-index polymers. Halogen atoms, olefin bonds, and benzene rings (large conjugated structures) are several high-refractive-index groups; among them, sulfur atoms have the best refractive index, only slightly yellowish. In organic light-emitting devices, fused heterocyclic aromatic hydrocarbons are considered materials with high light extraction efficiency. Ideal optical coating materials possess characteristics such as high refractive index, low light absorption in the visible light range, and relatively easy evaporation growth methods. These properties can be applied to organic electroluminescent devices to enhance light coupling output, improve external quantum efficiency, and reduce light loss within the device. Simultaneously, research shows that after surface two-dimensional microstructures are added, the refractive index and light extraction efficiency can also be improved to a certain extent in terms of applicability. Figure 7 This refers to the design route for the synthesis of high molecular weight, high refractive index materials in related technologies. For example... Figure 7 As shown, the synthetic design route for high molecular weight, high refractive index materials includes: evaporation and radical generation, SS bond cleavage, adsorption and initiation, and polymerization. Chemical vapor deposition (CVD) is a versatile and precise technique used to prepare polymer coatings and films for various applications. In related research, a 200 nm thick polymer (P4VP) film was prepared using CVD, followed by halogen vapor treatment to form a halopolymer film with a high refractive index. Alternatively, charge-transfer complexes increased the refractive index of the P4VP film from 1.58 to 2.0 or higher, while maintaining the conformability and smoothness of the deposited polymer film. Specifically, the P4VP-I2 complex has a refractive index of 2.0 and is transparent above 600 nm. In another formulation, the refractive index of P4VP combined with ICl reaches as high as 1.77, while maintaining excellent optical transparency throughout the visible and infrared range. By copolymerizing with other monomers inert to halogens to control the concentration of carbon tetrachloride in the polymer film, the refractive index of the halogenated polymer film can be further fine-tuned. This technique was used to experimentally prepare a series of P4VP films copolymerized with 1H,1H,6H,6H-perfluoro-1,6-hexyl diacrylate (PFHDA), with refractive indices ranging from 1.50 to 1.98.

[0046] In some embodiments, the first layer 11 has a heteroatom-containing conjugated polymer material, obtained by a hybrid flexible thiol / thiourethane (low modulus) and rigid thiol (high modulus) method.

[0047] For example, copolymerization can be achieved by selecting materials with different glass transition temperatures (Tg), i.e., copolymerization of materials with high and low Tg. The first layer (11) consists of conjugated polymer materials with heteroatoms, including: flexible segments of polythiols (C1-C10) or polythiourethanes; and rigid segments of heterocyclic systems, such as monomers containing thiophene, imidazole, pyrazole rings, benzene rings, and sulfur. A bridged cyclic olefin system can be added between rigid and flexible types, such as COP (Cycloolefin Polymer) cyclic olefin polymers, polynorbornene, etc.

[0048] In some embodiments, aromatic components are blocked into a polymer network of polysulfide and polyurethane to achieve both high elasticity and high refractive index in the first layer 11.

[0049] It has been verified that when the refractive index of the first layer 11 is greater than 1.6, the light intensity of the display panel 100 can be increased by 8-10%. Therefore, it is speculated that when the refractive index of the first layer 11 is greater than 1.75, the light intensity of the display panel 100 can be increased by 15-18%, which can effectively reduce power consumption.

[0050] In some embodiments, the first layer 11 may or may not have an adhesive function. The thickness of the first layer 11 is between 20 μm and 50 μm. The modulus of the first layer 11 is greater than or equal to 100 kPa and less than or equal to 300 kPa, thereby giving the first layer 11 good cohesive strength.

[0051] In some embodiments, before installation, the first layer 11 has a groove on the side of the first layer 11 facing the second layer 12. By providing the groove, it is convenient for residual gas between the first layer 11 and the second layer 12 to be discharged when the first layer 11 is attached to the second layer 12.

[0052] In some embodiments, multiple grooves are provided, and the multiple grooves are arranged in a grid pattern to further facilitate the impregnation and gas discharge, while greatly improving the degassing success rate and pull-out force.

[0053] In some embodiments, the groove of the first layer 11 matches the protrusion 121 of the second layer 12, that is, the protrusion 121 of the second layer 12 fits against the inner wall of the groove of the first layer 11.

[0054] In some embodiments, the first layer 11 is formed with a plurality of grooves on its side facing the second layer 12 by vacuum plasma treatment.

[0055] In some embodiments, the second layer 12 is microstructured by an organic pattern to form protrusions 121.

[0056] For example, the two opposite sides of the second layer 12 are the first side 1211 and the second side 1212 of the protrusion 121, and the third side 1213 of the protrusion 121 is formed by organic pattern microstructuring.

[0057] like Figure 3 and Figure 5 As shown, in some embodiments, the light-emitting layer 20 has a plurality of sub-pixel regions 21 arranged in an array, with the sub-pixel regions 21 located on the side of the light-emitting layer 20 facing the cover layer 10. The sub-pixel regions 21 are used to emit light of different colors to realize the image display function of the light-emitting layer 20. By misaligning the protrusion 121 with the sub-pixel regions 21, the protrusion 121 can reflect the scattered light emitted by the sub-pixel regions 21, thereby improving the brightness of the display panel 100 in the user's viewing direction.

[0058] In some embodiments, a plurality of protrusions 121 are provided. The plurality of protrusions 121 are arranged in an array to converge the scattered light from various locations of the light-emitting layer 20.

[0059] For example, multiple protrusions 121 are arranged in an array, and the main body of each protrusion 121 has a frustum structure with concave sides. The upper bottom surface of the frustum structure is the second side surface 1212 of the protrusion 121, the lower bottom surface of the frustum structure is the first side surface 1211 of the protrusion 121, and the concave side surface of the frustum structure is the third side surface 1213 of the protrusion 121.

[0060] In some embodiments, multiple protrusions 121 are provided. The protrusions 121 are elongated, and the length directions of each protrusion 121 are parallel to each other, which effectively reduces the processing difficulty.

[0061] Figure 3 This is a schematic diagram illustrating the structure of a display panel 100 according to another exemplary embodiment. For example... Figure 3 As shown, in some embodiments, the cover layer 10 has multiple layers. When the cover layer 10 processes the scattered light from the light-emitting layer 20, some of the scattered light will not pass through the protrusion 121, thus preventing its optical path from being altered. Therefore, by providing multiple cover layers 10, the processing effect on the scattered light from the light-emitting layer 20 is effectively improved.

[0062] like Figure 3 As shown, in the multilayer cover layer 10, the protrusions 121 included in the second layer 12 of any two adjacent cover layers 10 are staggered to increase the projection ratio of the protrusions 121 on the light-emitting layer 20, thereby improving the processing effect of the scattered light of the light-emitting layer 20.

[0063] In some embodiments, the protrusions 121 are elongated strips. The protrusions 121 included in the second layer 12 of any two adjacent cover layers 10 of the multilayer cover layer 10 are parallel to each other in their length direction or have a preset angle. That is, the projection of each protrusion 121 in the multilayer cover layer 10 onto the light-emitting layer 20 is striped or mesh-like, which further improves the processing effect of the scattered light of the light-emitting layer 20.

[0064] In some embodiments, when the protrusions 121 included in the second layer 12 of any two adjacent cover layers 10 of the multilayer cover layer 10 have a preset angle in the longitudinal direction, the preset angle is 90°, so that each protrusion 121 can respectively converge the scattered light in two mutually perpendicular directions of the light-emitting layer 20.

[0065] For example, Figure 4 This is a schematic diagram illustrating the structure of a display panel according to another exemplary embodiment, such as... Figure 4 As shown, the light-emitting side of the light-emitting layer 20 is provided with a first encapsulation film layer 13, a second encapsulation film layer 14, a third encapsulation film layer 15, a touch panel (TP) 16 and a cover layer 10 stacked in sequence.

[0066] For example, Figure 5 This is a schematic diagram illustrating the structure of a display panel according to another exemplary embodiment, such as... Figure 5 As shown, the light-emitting side of the light-emitting layer 20 is provided with a first encapsulation film layer 13, a second encapsulation film layer 14, a third encapsulation film layer 15, a buffer layer 17, a hole transport layer 18, a water and oxygen barrier layer 19, a cover layer 10 and a polarizer 30 stacked in sequence.

[0067] Figure 8 This is a schematic diagram of the adsorption process during the handling of the display panel 100 in related technologies. Figure 9 This is a schematic diagram illustrating the adsorption process of a display panel 100 during handling, according to an exemplary embodiment. Figure 8 As shown, in the related technology, the adsorption position 200 during the handling of the display panel 100 is close to the middle of the display panel 100, which can cause excessive deformation of the display panel 100, resulting in water stains. For example... Figure 9 As shown, the adsorption position 200 of the display panel 100 in this embodiment of the application is close to the end of the display panel 100 during transportation, which can effectively improve the problem of water stains.

[0068] Based on the same concept, this disclosure also provides an electronic device, including the display panel 100 described in any of the above embodiments.

For example, electronic devices can be handheld devices with wireless connectivity, in-vehicle devices, etc. Currently, examples of electronic devices include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices.
