Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The example embodiments described in the following example embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram of a display module in the related art. As shown in fig. 1, the display module generally includes a display module (e.g., a display panel 4) and a glass cover plate 3 covering the display module, the glass cover plate 3 and the display panel 4 can be connected by an optical adhesive 6, and the display module is mounted in an adhesive frame 7. As can be seen from fig. 1, a narrow gap B is formed between the rubber frame 7 and the edge of the display module. Some electronic devices (e.g., mobile phones) having a display module are usually configured with a Light Sensor (Light-Sensor)8, and the Light Sensor 8 is used for sensing ambient Light, so that the electronic device can adjust the brightness of the display module according to the ambient Light, and the electronic device is intelligent.
The related art typically places the light sensor 8 in the narrow slit gap B between the bezel 7 and the display module (see fig. 1). In the working process of the display module with the structure type, a part of light (shown by an arrow C in the figure) emitted from the display area 41 of the display panel 4 is emitted to the glass cover plate, and the other part of light (shown by an arrow D in the figure) is emitted to the narrow gap B between the rubber frame 7 and the edge of the display module from the peripheral edge of the display panel 4 through refraction, so that the side light leakage condition occurs, and the light sensing effect of the light sensor 8 located in the narrow gap B is affected. Especially, when the display panel is a 3D curved OLED (Organic Light-Emitting Diode) display screen, the phenomenon of side Light leakage is stronger.
To solve the above problem, the related art may dispense glue at the side of the display panel to block the light from exiting from the side, or place the light sensor at another position (e.g. under the display panel). In the actual use process, the shading effect of dispensing glue at the side edge of the display panel is not ideal, and particularly when the display panel is a 3D bent OLED display screen; and the light sensor at other positions will also cause the light sensing effect of the light sensor to be reduced, so that the above problems cannot be completely solved.
To this end, an embodiment of the present disclosure provides a display module, and fig. 2 is a schematic structural diagram of a display module according to an exemplary embodiment, as shown in fig. 2, the display module includes: glass apron 3, display panel 4 and light shield layer 1, one side of light shield layer 1 is connected with glass apron 3, and the another side of light shield layer 1 is connected with display panel 4 laminating.
The one side of the light shielding layer 1 is connected to the glass cover plate 3, which may mean that the one side of the light shielding layer 1 is directly attached to the glass cover plate 3, or that the one side of the light shielding layer 1 is indirectly connected to the glass cover plate 3, for example, the light shielding layer 1 and the glass cover plate 3 may be bonded by an optical adhesive.
In the present disclosure, the other side surface of the light shielding layer 1 is directly attached to the display panel 4, so that the light emitted from the display panel 4 can be prevented from being emitted from the gap between the light shielding layer 1 and the display panel 4 to cause side light leakage, thereby ensuring the light shielding effect of the light shielding layer 1.
Fig. 3 is a schematic structural diagram of a light-shielding layer provided according to an exemplary embodiment, and fig. 4 is a top view of a light-shielding layer provided according to an exemplary embodiment. As shown in fig. 3 and 4, the light-shielding layer 1 includes: a light-transmitting portion 11 and a shielding portion 12 surrounding the light-transmitting portion 11.
In the embodiment of this disclosure, display module assembly includes glass apron, display panel and light shield layer, and a side and the glass cover connection of light shield layer, another side and the display panel laminating of light shield layer are connected, and the light shield layer includes: a light-transmitting portion and a shielding portion surrounding the light-transmitting portion. When the display panel is used, the light shielding layer is attached to the display panel, light emitted by the display panel enters the light transmitting portion of the light shielding layer, the light entering the light transmitting portion is blocked by the blocking portion and is transmitted out of the light shielding layer from the blocking portion, and the light can be prevented from being emitted from a narrow gap between the display panel and the rubber frame, so that the problem of light leakage at the edge is avoided, and the light sensing effect of a light sensor located in the narrow gap is not influenced.
Alternatively, as shown in fig. 3, the thicknesses H of the light-transmitting portion 11 and the shielding portion 12 in the direction perpendicular to the light-shielding layer 1 are the same. That is, the thickness H of the light-shielding layer 1 remains unchanged in the direction perpendicular to the light-shielding layer 1. This ensures that no light entering the light-transmitting portion 11 of the light-shielding layer 1 from the display panel 4 exits the light-shielding layer 1 from the shielding portion 12, ensuring that the light-shielding layer 1 is completely light-tight. Also, the light-transmitting portion 11 and the shielding portion 12 may be integrally molded. For example, the light-transmitting portion 11 and the shielding portion 12 may be formed by a single manufacturing process, that is, the light-shielding layer 1 is formed by a single manufacturing process. Therefore, the processing and manufacturing efficiency of the light shielding layer 1 can be improved, and the production is convenient.
Alternatively, the shielding part 12 may be colored so that the shielding part 12 takes on different colors, wherein the colored means a process in which the dye enters the inside of the object from the outside of the object to make the object have a color. Therefore, the shielding part 12 is colored as a whole after the coloring treatment of the shielding part 12. After the shielding part 12 is dyed, since the shielding part 12 has a color capable of reflecting the light emitted from the light transmitting part 11 toward the shielding part 12, the light can be prevented from being emitted from the edge of the light shielding layer 1, thereby preventing the light leakage.
Illustratively, the colored shielding portion 12 may be in various colors such as black, gold, and the like. The shielding part 12 dyed black has a better effect of absorbing light and reflecting light emitted from the light transmitting part 11, and thus has a better light shielding effect than the shielding part 12 dyed other colors.
Note that the masking portion 12 may be dyed or embossed. The present disclosure is not limited as long as it is satisfied that the entirety of the shielding part 12 can be dyed in a desired color. The printing process in the printing process can be adopted during the dyeing of the printing process, such as water paste printing and glue paste printing, and the shielding part can be dyed into the required color.
Optionally, the light shielding layer 1 has a single-layer structure or a multi-layer structure. In the embodiment of the present disclosure, when the light-shielding layer 1 is a single-layer structure, the light-shielding layer 1 includes the light-transmitting portion 11 and the shielding portion 12 surrounding the light-transmitting portion 11. As shown in fig. 3, when the light-shielding layer 1 is a multilayer structure, the multilayer structure is a structure in which multiple layers of films are laminated together. By adopting the light shielding layer 1 with a multilayer structure, the thickness of the light shielding layer 1 can be increased, and the light shielding layer 1 can achieve the optimal light leakage prevention effect.
In other possible embodiments, only a portion of the film layers including the light-transmitting portion 11 and the shielding portion 12 may be disposed in the light-shielding layer 1 of the multi-layer structure, and the portion of the film layers is located at a position where the light-shielding layer 1 is attached to the display panel 3. Thus, the side light leakage can be effectively prevented, the processing steps for processing the light shielding layer 1 can be reduced, the processing and manufacturing are convenient, and the cost is saved.
In one possible structure of the light shielding layer, the light shielding layer 1 may include a transparent optical adhesive layer, that is, the material of the light shielding layer 1 is a transparent optical material. The transparent optical material may be OCA (optical clear optical adhesive). The OCA has an adhesive function, so that the transparent optical adhesive layer made of the OCA can adhere to the glass cover plate 3 and the display panel 4. The glass cover plate 3 and the display panel 4 can be bonded together while the use requirements of light transmission and shading are met, and the use is convenient.
For example, as shown in fig. 5, when the light-shielding layer 1 has a single-layer structure, the light-shielding layer 1 may be a transparent optical adhesive layer, and the transparent optical adhesive layer includes a light-transmitting portion 11 and a shielding portion 12. Wherein the blocking portion 12 of the transparent optical layer is black, the blocking portion 12 may be implemented by a dyeing process.
For example, as shown in fig. 6, when the light-shielding layer 1 has a multilayer structure, the light-shielding layer 1 may be a plurality of transparent optical adhesive layers laminated together, and each of the plurality of transparent optical adhesive layers includes a light-transmitting portion 11 and a shielding portion 12. Wherein the blocking portion 12 of the transparent optical layer is black, and the blocking portion 12 in black may be realized by a dyeing process.
In another possible structure of the light shielding layer, the light shielding layer 1 is a multi-layer structure, and the light shielding layer 1 may include a first transparent optical adhesive layer, an anti-reflection layer, and a second transparent optical adhesive layer, which are sequentially stacked. The first transparent optical adhesive layer and the second transparent optical layer are made of transparent optical materials, and the transparent optical materials can be OCA. In the present disclosure, the anti-reflection layer is disposed in the light-shielding layer 1, so that the transmittance can be increased, and the display panel 4 can have a good light-emitting effect. Meanwhile, two sides of the anti-reflection layer are bonded through the transparent optical adhesive layer, so that the anti-reflection layer can be conveniently bonded on other film layers or components (such as the glass cover plate 3 and the display panel 4).
Optionally, the antireflection layer may include the polarizer film layer 2. Meanwhile, the polarizer has the characteristic of converting a circular light source into a linear light source, and only light perpendicular to the polarizer is allowed to pass through the polarizer, so that the polarizer can convert divergent light rays into parallel light rays, and the converted parallel light rays are perpendicular to the polarizer. Therefore, the light rays entering the polarizer are perpendicular to the polarizer, so that the light rays in the polarizer are not reflected, and the polarizer is emitted from the edge of the polarizer, namely, the purpose of preventing the light rays from being emitted from the edge of the light shielding layer 1 can be effectively realized by arranging the polarizer, and the light leakage is prevented. For example, the polarizer film layer 2 may be an iodine-based polarizer, which can obtain high transmittance, thereby ensuring the light-emitting effect of the display panel 4.
Illustratively, as shown in fig. 7, the light-shielding layer 1 has a three-layer structure, which includes a first transparent optical layer, a polarizer film layer 2, and a second transparent optical layer from top to bottom, and each of the three-layer structure includes a light-transmitting portion 11 and a shielding portion 12. Wherein, the shielding parts 12 of the first transparent optical layer, the polarizer film layer 2 and the second transparent optical layer are all black, and the shielding parts 12 in black can be realized by dyeing treatment.
In one implementation of the present disclosure, the materials of the light-transmitting portion 11 and the shielding portion 12 may be the same. That is, the material of each portion in the light shielding layer 1 is the same, for example, the light shielding layer 1 is made of one material, the light transmitting portion 11 and the light shielding portion 12 are also made of the one material, and the light shielding layer 1 can be manufactured as an integral structure by one process. The shielding part 12 of the light shielding layer 1 can be processed by other processes to have the effect of shielding light from exiting. The light-transmitting part 11 and the shielding part 12 are made of the same material, so that the processing and manufacturing efficiency of the light shielding layer 1 is improved, the cost is saved, and the production is facilitated.
In another implementation of the present disclosure, the materials of the light-transmitting portion 11 and the shielding portion 12 may be different. That is, the light-transmitting portion 11 and the shielding portion 12 in the light-shielding layer 1 are made of different materials, for example, the light-shielding layer 1 may be formed by splicing two materials, the light-transmitting portion 11 is a transparent optical material, the transparent optical material may be OCA, the shielding portion 12 is an opaque material, and the opaque material may be polypropylene resin. When the light transmitting portion 11 and the shielding portion 12 are joined, the shielding portion 12 may be bonded to the light transmitting portion 11. Because the shielding part 12 in the spliced light shielding layer 1 can realize complete light impermeability, the light shielding effect is optimal.
Illustratively, as shown in fig. 8, the light-shielding layer 1 is a three-layer structure, each of which includes a light-transmitting portion 11 and a shielding portion 12, wherein the light-transmitting portion 11 is made of an OCA material, and the shielding portion 12 is made of a polypropylene resin material.
Fig. 9 is a schematic structural diagram of a display panel provided according to an exemplary embodiment. As shown in fig. 9, the display panel 4 includes a display area 41 and a non-display area 42 surrounding the display area 41, and the width L of the non-display area 42 is 1mm to 3 mm. The size of the transparent portion 11 of the light-shielding layer 1 is the same as the display area 41 of the display panel, so that when the light-shielding layer 1 is attached to the display panel 4, the orthographic projection of the transparent portion 11 of the light-shielding layer 1 on the display panel 4 can be overlapped with the display area 41 of the display panel 4, and the orthographic projection of the shielding portion 12 of the light-shielding layer 1 on the display panel 4 is located in the non-display area 42 of the display panel 4. In addition, the bonding tolerance of the light shielding layer 1 and the display panel 4 after bonding is ± 0.3mm, so that the display effect is not affected by the shielding part 12 shielding the display area 41 of the display panel 4.
The Display panel may be an OLED (Organic Light-Emitting Diode), an LCD (Liquid Crystal Display), and other Display devices.
Fig. 10 is a schematic structural diagram of a display module according to an exemplary embodiment. As shown in fig. 10, the display module generally includes a display panel 4 and a glass cover plate 3 covering the display panel 4, the glass cover plate 3 and the display panel 4 can be connected by a light shielding layer 1, and the display module is mounted in a rubber frame 7. Wherein, the display module assembly still includes light sensor 8, and light sensor 8 is located the outside of sheltering from part 12. Wherein, the outside of the shielding part means: in the layer surface where the shielding part 12 is located, a position area around the shielding part 12. The plane in which the shielding portion 12 is located is a set of all planes parallel to the shielding portion 12 and passing through the shielding portion 12. For example, the transparent portion 11 is located inside the shielding portion 12, and the shielding portion 12 is located outside the shielding portion 12 on the side opposite to the transparent portion 11. Combine fig. 10 to know, glue and have slot clearance B between the edge of frame 7 and display module assembly, and light sensor 8 is located slot clearance B department, because the light shield layer can effectively prevent the display module assembly problem that the side light leak from appearing, therefore makes light sensor 8 can high-efficiently feel ambient light, makes electronic equipment can adjust the luminous luminance of display module assembly according to ambient light, makes electronic equipment intelligent.
