Please refer to FIG. 1 and FIG. 2 together. FIG. 1 is a schematic diagram of the overall structure of an embodiment of the electronic device of the present application. FIG. 2 is a schematic diagram showing the structure of the electronic device in the embodiment of FIG. 1. It should be noted that the electronic devices in the embodiments of the present application include mobile phones, notebook computers, tablet computers, and wearable devices.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally also includes Other steps or units inherent to these processes, methods, products or equipment.

At present, the trend of full-screen electronic products such as mobile phones is becoming more and more obvious. In-screen digging has gradually become a trend, and various terminal manufacturers have launched in-screen perforation products. In order to ensure the display effect and minimize the impact of screen openings on users, display solution providers and mobile phone terminals are trying their best to reduce the aperture size. Among them, the blind hole solution, that is, the solution of partial transparency of the screen glass, can reduce the clearance between the front camera and the surrounding mechanism of the whole machine, and it is a better solution to achieve a smaller aperture at present.

Specifically, the electronic equipment in the embodiments of the present application includes, but is not limited to: a display screen assembly 10, an optical device 12, a housing 14, a circuit board 16, a battery 18, and a display screen cover 20. The housing 14 cooperates with the display cover 20 to form an accommodating cavity (not marked in the figure), and the optical device 12, the display assembly 10, the circuit board 16 and the battery 18 are all arranged in the Housed in the cavity.

Of course, the electronic device also includes other components, which will not be listed and detailed here.

Please refer to FIG. 3, which is a schematic cross-sectional view of a partial structure at AA in FIG. 2 of the traditional technical solution; FIG. 4 is a schematic cross-sectional view of a partial structure at AA in FIG. 2 of an embodiment of the present application; FIG. 5 is FIG. 4 The schematic diagram of the optical path structure of the embodiment in the embodiment; among them, FIGS. 3 to 5 only illustrate the structure of the optical device and the display screen assembly of the electronic device. The display screen assembly 10 includes a stacked light refraction layer, a number of light-transmitting material layers, and a number of non-light-transmitting material layers. The display screen assembly has a partial light-transmitting area, and the partial light-transmitting area may be a circle or a drop shape. Wherein, in this embodiment, a circular shape is used for description, and the specific shape of the partial light-transmitting area is not limited. The plurality of non-light-transmitting material layers have no non-light-transmitting material at the local light-transmitting area, that is, the local light-transmitting area is stacked corresponding to either all light-transmitting material layers, or the non-light-transmitting material layer is hollowed out or Light-transmitting treatment; in the embodiment of Figures 4 and 5, the transparent material layer and the non-light-transmitting material layer are stacked corresponding to the local light-transmitting area. In other words It is said that the light-transmitting area in this embodiment is a blind hole structure, that is, the light-transmitting area is a non-through hole structure that only transmits light; a plurality of light-transmitting material layers and a plurality of non-light-transmitting material layers are formed along the stacking direction in the partial light-transmitting area The light-transmitting channel W1; the light-transmitting channel W1 is set corresponding to the optical device 12.

In this embodiment, an OLED display screen structure is used for description. The display screen assembly 10 may specifically include a polarizing layer 102, an encapsulation layer 104, and a display substrate 106 that are stacked in sequence. Wherein, the polarizing layer 102 can be bonded to the display screen cover 20 through the optical adhesive layer 100. After determining the position of the front camera according to the appearance definition, the display assembly needs to be blind hole processed in the light-transmitting area. A specific implementation manner may be that no electrode is plated on the upper surface of the display substrate 106 (LTPS), and the polarizing layer 102 is hollowed out at the corresponding position or partially failed. The rest of the encapsulation layer 104, the optical adhesive layer 100, etc. have higher transmittance and have little influence on the front imaging. Therefore, a circular transparent area is formed here for the front lens to view. It should be noted that all the directional indicators (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the difference between the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the relative positional relationship, movement conditions, etc., the directional indication will also change accordingly.

The optical device 12 is disposed under the transparent area of the blind hole. The optical device 12 may include at least one of a camera module, a flashlight, and a sensor. In this embodiment, the camera module is used for description. The center of the light transmission channel W1 can be aligned with the focus of the camera. External light enters from the light transmission channel W1, and the front camera receives and forms an image. In order to achieve the designed imaging effect, the front camera module must ensure a certain FOV (field of view); in this embodiment, the edge of the polarizing layer 102 is the limit angle of the field of view light (the dotted line in FIG. 3), The edge light enters from the edge of the polarizing layer 102, passes through the display substrate 106 and the air boundary, is refracted, and enters the camera module. It can be seen from FIG. 3 and the above content that the diameter of the light transmission channel W1 is the edge of the polarizing layer 102. Therefore, the requirement of the FOV of the front camera module determines the edge position of the polarizing layer 102, that is, the size of the light transmission channel W1.

The FOV of the front camera is generally required to be between 80-120°, otherwise it will affect the imaging and reduce the user experience. Limited by the assembly process, the camera must also leave a certain gap T with the bottom of the display screen. The thickness of each laminated layer of the display module is relatively fixed, so the aperture of each blind hole solution (that is, the light transmission channel W1) is not much different. In the conventional blind hole screen solution, the aperture is generally 3-4mm, the aperture is larger, and the overall visual effect is poor, which affects the display of the screen as a whole, and the user experience is poor.

Based on the above problems, the technical solution in this embodiment adds a light refraction layer 108 structure. The light refraction layer 108 is arranged corresponding to the light transmission channel W1. The area of the light refraction layer 108 in the figure in this embodiment is the same as The size of the light transmission channel W1 is the same or approximately the same, as long as it can ensure that the light path can pass through the light refraction layer 108 when propagating along the light transmission channel W1. In this embodiment, the area size and light transmission of the light refraction layer 108 are not adjusted. The relationship between the area of the channel W1 is specifically defined.

Wherein, the refractive index of the light refraction layer 108 is greater than the refractive index of the material layer adjacent to it. In the embodiment of FIG. 5, the light refraction layer 108 is embedded in the encapsulation layer 104, and its two sides are respectively adjacent to the encapsulation layer 104 and the display substrate 106. In this embodiment, the refractive index of the light refraction layer 108 needs to be greater than that of the encapsulation layer. 104 and display the refractive index of at least one of the substrate 106. In addition, in other embodiments, the light refraction layer may also be embedded in any one of the light-transmitting material layer and the non-light-transmitting material layer, which will not be listed and detailed here.

Optionally, the light refraction layer 108 may be a solid film or a liquid material. Specifically, the surface of the encapsulation layer 104 may be locally polished and polished to form a groove. The light refraction layer 108 is added to this groove. The light refraction layer 108 can be a transparent liquid or solid transparent material with a refractive index greater than that of glass (the material of the encapsulation layer 104 and the display substrate 106 is about 1.5). The addition is completed before the encapsulation layer 104 and the display substrate 106 are packaged. At this time, the light path of the display module is shown in Figure 6 for the double refraction light path. Please refer to Figures 5 to 7 together. Figure 6 is a schematic diagram of the light path of the partially laminated structure of the display assembly in Figure 5; Figure 7 is the display screen Schematic diagram of the change of the light transmission channel of the component.

It can be clearly seen from FIGS. 6 and 7 that after the light refraction layer 108 is added, the light path is refracted on the encapsulation layer 104 once more. On the premise that the FOV remains unchanged, the required edge light incident point of the polarizing layer 102 is obviously shifted by a distance of L from the center. That is, the edge of the polarizing layer 102 can be compressed inward, and the circular transparent area becomes smaller accordingly. The overall aperture is reduced from W1 to W2, and the single side is reduced by L, and the diameter of the aperture is reduced by 2L.

The angle of incidence of the encapsulation layer 104 is α, the thickness d of the light refraction layer 108, and the relative refractive index of the light refraction layer 108 to the encapsulation layer 104 (ie glass) is n; Push inward:

The refractive index of the light refraction layer 108 is greater than that of the encapsulation layer 104, that is, n>1, so L is always positive and increases as d increases. That is, the thicker the light refraction layer 108, the larger the refractive index, the smaller the inner diameter can be made on the basis of the original technical solution.

Wherein, FIG. 6 only shows a schematic diagram of the optical path when the refractive index of the light refraction layer 108 is greater than that of the adjacent encapsulation layer 104 and the display substrate 106. In some other embodiments, the light refraction layer 108 The refractive index of may also be greater than the refractive index of one of the encapsulation layer 104 and the display substrate 106 adjacent to it, that is, the refractive index of the light refraction layer 108 is located between the encapsulation layer 104 and the display substrate 106. This structural form The optical path diagram of is within the understanding of those skilled in the art, and will not be repeated here.

The manufacturing method of the display screen assembly may be to first make multiple packaging units on a large packaging material board, and locally polish and polish the corresponding position of the unit structure of each display assembly, that is, the circular transparent area. The thickness is as large as possible while ensuring the strength of the encapsulation layer. There are at least two ways to form the light refraction layer: 1. Use a transparent liquid with a large refractive index, which can be dripped quantitatively into the slot position; 2. Use a transparent solid material with a large refractive index (such as a film) , Can design the soft adhesiveness on the contact surface of the film material and the encapsulation layer and carry out the alignment bonding. After the addition of the light refraction layer is completed, the large encapsulation layer is used as the base to encapsulate the display substrate 106 as a whole, and finally cut into a plurality of independent display screen assembly unit structures. Please refer to FIG. 8. FIG. 8 is a schematic diagram of a structure of a plurality of display screen components being integrally packaged.

In addition, it should be noted that the technical solution in this embodiment is not limited to the structure of an OLED display screen, and may also be a structure of a liquid crystal display screen. Correspondingly, the display substrate 106 may be a TFT substrate, and the encapsulation layer 104 may be a CF (Color Filter, color filter) layer. Specifically, it may be to remove or thin a part of the liquid crystal material between the TFT substrate and the CF layer, and add The light refraction layer can also undergo one more refraction to obtain a smaller transparent aperture when the FOV is fixed. The detailed structural features of the liquid crystal display are within the understanding of those skilled in the art, and will not be repeated here.

Please refer to FIG. 9, which is a schematic structural diagram of another embodiment of the display assembly and the optical device in the embodiment of the present application. The difference from the foregoing embodiment is that the light refraction layer 108 of the display assembly in this embodiment is A solid film sandwiched between the display substrate 106 and the encapsulation layer 104. Of course, the light refraction layer 108 can also be between other material layers, as long as it is on the light transmission channel. Among them, the light refraction layer The area of 108 may be the same as that of the display substrate 106. As long as it is ensured that the light refraction layer 108 can cover the light transmission channel W1.

Further, please refer to FIG. 10, which is a schematic diagram of the light path structure of another embodiment of the display screen assembly in the embodiment of the present application; in this embodiment, the display screen assembly 10 is embedded with two light refraction layers 108, two The two light refraction layers 108 are respectively embedded in the display substrate 106 and the encapsulation layer 104. Compared with the foregoing embodiment, the technical solution in this embodiment is provided with one more light refraction layer 108, which can further reduce the size of the aperture W1. After two refractions, compared with W2 in the foregoing embodiment, the technical solution in this embodiment can reduce the aperture from W1 to W3. In the figure, the solid line represents the actual path of the optical path, and the dotted line represents the propagation path of the optical path without the light refraction layer 108. For the specific refraction principle, please refer to the relevant description in the foregoing embodiment. It needs to be described that this embodiment can also be transformed into a large-area, non-embedded light refraction layer as shown in FIG. 9; in addition, the specific material layers of the light refraction layer 108 are not limited to what is shown in the figure. In the situation. Under the idea of this embodiment, a plurality of light refraction layers stacked along the light transmission direction of the light transmission channel can also be provided. The more light refraction layers there are, the more the aperture can be reduced. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

The structure, that is, the junction between the light refraction layer 108 and the encapsulation layer 104 is a curved surface; by providing the light refraction layer 108 with a convex lens structure, the aperture can be further reduced. It can be seen from the figure that the light path travels along the dashed line X1 without the light refraction layer, and the aperture is W1. When the light refraction layer is provided with a sheet or rectangular cross-section (the dashed frame in the figure represents a rectangular structured light In the case of the refractive layer), the light path will propagate along the dashed line X2, and the aperture can be reduced to W2. When the light refraction layer 108 with a convex lens structure is provided, the light path propagates along the solid line, and the aperture can be reduced to W4. Obviously, by setting The light refraction layer with a convex lens structure can further reduce the aperture.
