Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a display panel and a display device. Background Technology

[0002] With the development of display technology, laptops have become increasingly popular. Typically, a light-transmitting hole is provided above the laptop screen for the webcam module, and a layer of black light-blocking tape is applied around the hole. Usually, when there is enough space at the edges, this light-blocking tape is designed to completely surround the light-transmitting hole; however, in situations where space is limited, such as... Figure 1 As shown, the light-shielding tape 1' of the display screen 11' of the laptop 10' can only be designed as a semi-open hole, for example, the light-shielding tape 1' partially surrounds the light-transmitting hole 2'. However, in practical applications, it has been found that the semi-open hole light-shielding tape design has the problem of foreign object contamination, which seriously affects the performance of the camera module.

[0003] Therefore, how to solve the problem of low performance of camera modules caused by semi-open light-blocking tape has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To solve at least one of the above problems, a first embodiment of the present invention provides a display panel including a camera light-transmitting hole, a light-shielding tape partially surrounding the camera light-transmitting hole, and a protective film covering the camera light-transmitting hole and the light-shielding tape. The display panel includes a camera area, which includes a hole area corresponding to the light-transmitting hole of the camera, a light-shielding area corresponding to the light-shielding tape, and a blank area other than the hole area and the light-shielding area. The protective film comprises at least two protective sub-films, each including a first protective sub-layer and a second protective sub-layer disposed on the side of the first protective sub-layer near the blank area. The first protective sublayer covers the blank area, the perforated area, and the light-shielding tape; The second protective sub-layer is arranged side by side with the light-shielding tape. The orthographic projection of the second protective sub-layer onto the first protective sub-layer and the orthographic projection of the blank area onto the first protective sub-layer at least partially overlap, based on the fact that the first protective sub-layer, the second protective sub-layer, and the light-shielding tape are flush.

[0005] For example, in some embodiments of the display panel provided in this application, the protective film is composed of a first protective sublayer and a second protective sublayer. Based on the first protective sub-layer, the thickness of the second protective sub-layer is the same as the thickness of the light-shielding tape.

[0006] For example, in some embodiments of the display panel provided in this application, the light-shielding tape includes a half-open hole corresponding to the light-transmitting hole of the camera, and the second protective sub-layer includes a protrusion corresponding to the half-open hole, the protrusion being embedded in the half-open hole.

[0007] For example, in some embodiments of the display panel provided in this application, at least one end of the protective film extends outward along the edge of the light-shielding tape to form a first operating portion; The display panel further includes a first tear-off portion disposed on the side of the protective film away from the light-shielding tape and covering the first operating portion.

[0008] For example, in some embodiments of the display panel provided in this application, the first protective sublayer is a transparent single-sided adhesive, which is directly attached to the light-shielding tape; The second protective sub-layer is a transparent polyester film, or the second protective sub-layer is a transparent single-sided adhesive and is directly attached to the first protective sub-layer; The first tear-off part is a single-sided adhesive and is directly attached to the first protective sub-layer.

[0009] For example, in some embodiments of the present application, the protective film includes a third protective sublayer and a fourth protective sublayer that are sequentially stacked on the first protective sublayer, and the fourth protective sublayer is directly attached to the light-shielding tape. The second protective sub-layer is disposed on one side of the third protective sub-layer, the fourth protective sub-layer, and the light-shielding tape; Based on the first protective sub-layer, the thickness of the second protective sub-layer is the same as the sum of the thicknesses of the third protective sub-layer, the fourth protective sub-layer, and the light-shielding tape.

[0010] For example, in some embodiments of the present application, the fourth protective sub-layer includes an adhesive portion that is attached to the light-shielding tape, and the orthographic projection of the adhesive portion on the first protective sub-layer overlaps with the orthographic projection of the light-shielding tape on the first protective sub-layer. The orthographic projection of the third protective sublayer onto the first protective sublayer overlaps with the orthographic projection of the fourth protective sublayer onto the first protective sublayer.

[0011] For example, in the display panel provided in some embodiments of this application, at least one end of the first protective sublayer extends outward along the edge of the light-shielding tape to form a second operating portion; The fourth protective sublayer also includes an extension that partially covers the second operating part; The second protective sublayer includes a first portion that at least partially covers the blank area and a second portion that partially covers the second operating portion; The protective film further includes a second tear-off portion disposed on the side of the fourth protective sublayer away from the third protective sublayer, wherein the orthographic projection of the second tear-off portion onto the first protective sublayer falls into the orthographic projection of the extension portion onto the first protective sublayer.

[0012] For example, in some embodiments of the display panel provided in this application, the first protective sublayer is a transparent polyester film; The second protective sublayer is a transparent single-sided adhesive. The third protective sublayer is a transparent double-sided adhesive, which is attached to the first and fourth protective sublayers respectively; The fourth protective sub-layer is a transparent single-sided adhesive, which is directly attached to the light-shielding tape; The second tear-off part is a single-sided adhesive and is directly attached to the fourth protective sub-layer.

[0013] For example, in some embodiments of the display panel provided in this application, the thickness of the first protective sublayer is greater than the thickness of the light-shielding tape.

[0014] A second embodiment of the present invention provides a display device, including a display panel as described in the first embodiment with a protective film removed.

[0015] The beneficial effects of this invention are as follows: This invention addresses existing problems by providing a display panel and display device. It utilizes a protective film with a composite layer to protect semi-open light-shielding tape. On one hand, a protective sub-layer of the protective film compensates for the unclosed portion of the semi-open light-shielding tape; on the other hand, another protective sub-layer covers the camera area where the camera's light-transmitting hole is located. This compensates for the unclosed portion by using the protective sub-layer and protects the entire camera area from foreign objects entering, thus overcoming the problems in existing technologies, effectively improving the performance of the camera module, and consequently increasing the product yield of the display device. It has practical application value. Attached Figure Description

Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that the terms "on," "formed on," and "set on" used in this document can indicate that one layer is directly formed or set on another layer, or that one layer is indirectly formed or set on another layer, meaning that there are other layers between the two layers. In this document, unless otherwise stated, the term "located on the same layer" means that two layers, components, elements, or parts can be formed through the same patterning process, and that these two layers, components, elements, or parts are generally formed of the same material. In this document, unless otherwise stated, the description of "patterning process" generally includes steps such as photoresist coating, exposure, development, etching, and photoresist stripping. The description of "one-time patterning process" refers to a process that uses a single photomask to form patterned layers, components, elements, etc.

[0020] To address the above situation, the inventors, through extensive experiments, pointed out that due to the space constraints of the narrow bezel, the light-shielding tape, arranged in a U-shape around the left, bottom, and right sides of the camera's light-transmitting hole, leaves an opening only on the top side. This black light-shielding tape is used to block the metal traces and bezel structure around the camera's light-transmitting hole, suppressing light leakage and also providing some side dust protection. Because the light-shielding tape cannot completely seal the camera's light-transmitting hole, an open channel for foreign objects to enter the hole is formed in the unsealed area, making the glass surface of the display panel substrate corresponding to the camera module susceptible to contamination by foreign objects.

[0021] like Figures 2-3 As shown, an embodiment of the present invention provides a display panel 11, including an array substrate and a color filter substrate of a pair of cells. The display panel includes a camera light-transmitting hole 2, a light-shielding tape 1 partially surrounding the camera light-transmitting hole 2, and a protective film 3 covering the camera light-transmitting hole 2 and the light-shielding tape 1. The display panel includes a camera area 4, which includes a hole area corresponding to the light-transmitting hole 2 of the camera, a light-shielding area corresponding to the light-shielding tape 1, and a blank area other than the hole area and the light-shielding area. The protective film 3 includes at least two protective sub-films, each including a first protective sub-layer 31 and a second protective sub-layer 32 disposed on the side of the first protective sub-layer 31 near the blank area. The first protective sub-layer 31 covers the blank area, the hole area, and the light-shielding tape 1; The second protective sub-layer 32 is arranged side by side with the light-shielding tape 1. The orthographic projection of the second protective sub-layer 32 on the first protective sub-layer 31 and the orthographic projection of the blank area on the first protective sub-layer 31 at least partially overlap, based on the fact that the first protective sub-layer 31, the second protective sub-layer 32 and the light-shielding tape 1 are flush.

[0022] In this embodiment, a protective film with a composite layer is used to protect the semi-open light-shielding tape. On one hand, a protective sub-layer of the protective film compensates for the unclosed portion of the semi-open light-shielding tape; on the other hand, another protective sub-layer covers the camera area where the camera's light-transmitting hole is located. This compensates for the unclosed portion by occupying space, and protects the entire camera area by preventing foreign objects from entering, effectively improving the performance of the camera module and thus increasing the product yield of the display device. In one specific embodiment, for a display panel used in a narrow-bezel laptop, such as Figures 2-3 As shown, a camera light-transmitting hole 2 is provided on the display panel 11, and a light-shielding tape 1 with a semi-open hole is partially surrounding the camera light-transmitting hole 2. A camera area 4 is provided on the display panel 11 formed by the array substrate and the color filter substrate. The camera area 4 is divided into an aperture area, a light-shielding area, and a blank area. The aperture area is the area corresponding to the camera light-transmitting hole, which is the light-transmitting channel reserved on the display panel by the camera module to facilitate the camera module to collect external light. The light-shielding area is the area surrounded by the camera light-transmitting hole and covered with light-shielding tape. The blank area is the area of ​​the camera area other than the aperture area and the light-shielding area, including the area where the semi-open hole of the light-shielding tape is not closed and the edge area. The display panel also includes a peelable protective film, which is attached to the surface of the camera area. It provides protection for the camera light-transmitting hole during the manufacturing process and transportation stages of the display panel, and is completely removed during the assembly stage to prevent foreign objects from entering during the manufacturing process. The protective film is a composite layer structure, including a first protective sublayer and a second protective sublayer stacked together. The second protective sublayer is disposed on the side of the first protective sublayer near the blank area, that is, the second protective sublayer is located between the first protective sublayer and the display panel substrate.

[0023] like Figure 3As shown, the protective film 3 covers the camera's light-transmitting hole 2, the blank area, and the light-shielding tape 1. The first protective sub-layer 31 serves as the substrate for the protective film, covering the hole area, the blank area, and the light-shielding tape. The second protective sub-layer 32 is disposed on the side of the first protective sub-layer 31 facing the display panel. The orthographic projection of the second protective sub-layer onto the first protective sub-layer falls within the orthographic projection of the blank area onto the first protective sub-layer. The second protective sub-layer and the light-shielding tape are arranged side-by-side. The surface of the second protective sub-layer 32 away from the first protective sub-layer 31 is flush with the surface of the light-shielding tape 1 away from the first protective sub-layer 31. In other words, the second protective sub-layer at least partially covers the blank area on the plane and fills the corresponding space in terms of thickness. In other words, this embodiment uses a protective film with at least two composite sub-layers to achieve graded protection for the light-shielding tape with a semi-open design: the first protective sub-layer covers the entire camera area, building an overall dustproof barrier from the outside to block most external foreign objects; the second protective sub-layer, by setting a compensating edge-blocking structure in the blank area, together with the light-shielding tape, forms a closed enclosure to block the foreign object channel caused by the semi-open design, thus providing a secondary barrier against fine dust that penetrates the first protective sub-layer; at the same time, the structural design of the second protective sub-layer being flush with the light-shielding tape ensures a smooth and adherent protective film, avoiding the risk of dirt accumulation and edge lifting caused by step gaps, further improving the protection performance against foreign objects and increasing the overall yield rate.

[0024] In an optional embodiment, such as Figure 4 and Figure 5 As shown, the protective film is composed of a first protective sublayer 31 and a second protective sublayer 32. Based on the first protective sub-layer 31, the thickness of the second protective sub-layer 32 is the same as the thickness of the light-shielding tape 1.

[0025] In this embodiment, Figure 4 This is an exploded diagram illustrating the structure of the protective film and light-blocking tape. Figure 5This is a top view of the protective film and light-shielding tape with the first protective sublayer as the base layer. The protective film consists only of a first protective sublayer 31 and a second protective sublayer 32, resulting in a simple structure that is easy to process and manufacture. The first protective sublayer 31 is a transparent single-sided adhesive, directly attached to the light-shielding tape 1. The second protective sublayer 32 is a transparent polyester film, with one surface in contact with the display panel substrate and the other surface attached to the single-sided adhesive side of the first protective sublayer. To further improve the adhesion between the second protective sublayer 32 and the first protective sublayer 31, the second protective sublayer 32 is a transparent single-sided adhesive, with the single-sided adhesive side directly attached to the single-sided adhesive side of the first protective sublayer. In this embodiment, to ensure the protection of the blank area on the display panel surface and in the space by the second protective sub-layer, the thickness of the second protective sub-layer is set to be the same as the thickness of the light-shielding tape. The second protective sub-layer and the light-shielding tape together form a closed edge around the camera hole. By setting a protective film with two protective sub-layers, this embodiment effectively eliminates the height difference between the light-shielding area and the blank area to ensure that the protective film is flat and adhered, effectively sealing the foreign object channel at the semi-open hole.

[0026] Furthermore, such as Figure 5 As shown, the light-shielding tape includes a semi-open hole corresponding to the light-transmitting hole of the camera, and the second protective sub-layer 32 includes a protrusion 321 corresponding to the semi-open hole, the protrusion 321 being embedded in the semi-open hole.

[0027] Considering that the protective film has only a two-layer structure, to prevent external pressure from causing adhesive residue to form on the display panel, this embodiment sets a second protective sub-layer that matches the light-shielding tape. Specifically, the light-shielding tape has a semi-open hole structure that is a recess, and the second protective sub-layer includes a retaining edge corresponding to the blank area and a protrusion corresponding to the hole area. The protrusion is embedded in the semi-open hole and matches the recess, forming a structure as shown in the figure. Figure 5 As shown in the top view, the protrusion 321 of the second protective sub-layer 32 is embedded in the semi-open hole of the light-shielding tape 1, and exposes the bottom first protective sub-layer 31. Thus, the protrusion of the second protective sub-layer at least partially fills the gap between the first protective sub-layer and the display panel, effectively resisting external pressure. At the same time, it prevents the adhesive surface from contaminating the display screen and forming adhesive marks on the display panel when the protective film is squeezed by the adhesion pressure.

[0028] In an optional embodiment, such as Figure 4 As shown, at least one end of the protective film extends outward along the edge of the light-shielding tape to form a first operating portion 33; The display panel also includes a first tear-off portion 5 disposed on the side of the protective film away from the light-shielding tape and covering the first operation portion 33.

[0029] In this embodiment, to facilitate the removal of the protective film during the assembly process, at least one end of the protective film is extended outward to form a first operating portion 33. A first tear-off portion 5 is provided on the first operating portion as a marker, for example, by providing a first tear-off portion with a prominent color for easy identification and operation. Furthermore, to improve the adhesion between the first tear-off portion and the protective film, the first tear-off portion is a single-sided adhesive, with the adhesive side directly attached to the first protective sub-layer. When assembling the entire machine, the entire protective film can be removed in one go using the first tear-off portion and the extended first operating portion, effectively improving the operability of the protective film.

[0030] In another alternative embodiment, such as Figures 6-7 As shown, the protective film includes a third protective sub-layer 34 and a fourth protective sub-layer 35 sequentially stacked on the first protective sub-layer 31, and the fourth protective sub-layer 35 is directly attached to the light-shielding tape 1; The second protective sub-layer 32 is disposed on one side of the third protective sub-layer 34, the fourth protective sub-layer 35 and the light-shielding tape 1; Based on the first protective sub-layer 31, the thickness of the second protective sub-layer 32 is the same as the sum of the thicknesses of the third protective sub-layer 34, the fourth protective sub-layer 35, and the light-shielding tape 1.

[0031] In this embodiment, Figure 6 This is an exploded diagram illustrating the structure of the protective film and light-blocking tape. Figure 7This is a top view of the protective film and the light-shielding tape with the first protective sublayer as the base layer. The protective film includes a first protective sublayer 31, a second protective sublayer 32 disposed on the first protective sublayer 31, and a third protective sublayer 34 and a fourth protective sublayer 35 disposed on the first protective sublayer 31. The fourth protective sublayer 35 is directly attached to the light-shielding tape 1. The stacked third protective sublayer, fourth protective sublayer, and light-shielding tape are arranged side by side with the second protective sublayer 32, and the thickness of the three stacked film layers is the same as the thickness of the second protective sublayer. In this embodiment, to improve the adhesion performance between the protective film and the light-shielding tape, a third protective sublayer 34 and a fourth protective sublayer 35 that are attached to the light-shielding tape and stacked are disposed on one side of the second protective sublayer. Specifically, the first protective sub-layer 31 is a transparent polyester film, and the second protective sub-layer 32 is a transparent single-sided adhesive. The third protective sub-layer 34 is a transparent double-sided adhesive, which is attached to the first protective sub-layer 31 and the fourth protective sub-layer 35 respectively. The fourth protective sub-layer 35 is a transparent single-sided adhesive, which is directly attached to the light-shielding tape 1. Meanwhile, to ensure that the second protective sub-layer 32 protects the blank area on the display panel surface and in the space, the thickness of the second protective sub-layer is set to be the same as the sum of the thicknesses of the stacked third protective sub-layer 34, fourth protective sub-layer 35, and light-shielding tape 1. The second protective sub-layer, together with the stacked third protective sub-layer 34, fourth protective sub-layer 35, and light-shielding tape, forms a closed edge around the camera hole. This embodiment, by setting a protective film with multiple protective sub-layers, effectively eliminates the height difference between the light-shielding area and the blank area to ensure that the protective film adheres smoothly and effectively seals the foreign object channel at the semi-open hole.

[0032] To further improve adhesion performance with light-blocking tape, in an optional embodiment, such as Figure 6 , Figure 8 As shown, the fourth protective sub-layer 35 includes an adhesive portion 351 that is attached to the light-shielding tape 1. The orthographic projection of the adhesive portion 351 on the first protective sub-layer 31 overlaps with the orthographic projection of the light-shielding tape 1 on the first protective sub-layer 31. The orthographic projection of the third protective sublayer 34 onto the first protective sublayer 31 overlaps with the orthographic projection of the fourth protective sublayer 35 onto the first protective sublayer 31.

[0033] In this embodiment, by setting the third and fourth protective sub-layers to conform to the light-shielding tape, multiple film layers can be aligned with the outline of the light-shielding tape, avoiding misalignment between layers and adhesive residue in the hole area. At the same time, the conformal stacking of the three film layers improves the adhesion performance between the protective film and the light-shielding tape. Combined with the second protective sub-layer on the side, it ensures the surface and space occupancy of the blank area, effectively preventing dust or foreign objects from entering the camera hole position, avoiding affecting the performance of the camera module, thereby improving the overall yield of the display panel.

[0034] To facilitate the removal of the protective film during the assembly process, in another optional embodiment, such as... Figures 6-9 As shown, at least one end of the first protective sublayer 31 extends outward along the edge of the light-shielding tape 1 to form a second operating portion 36. The fourth protective sublayer 35 also includes an extension 352 that partially covers the second operating part 36; The second protective sublayer 32 includes a first portion 322 that at least partially covers the blank area, and a second portion 323 that partially covers the second operating portion 36; The protective film also includes a second tear-off portion 6 disposed on the side of the fourth protective sub-layer 35 away from the third protective sub-layer 34, wherein the projection of the second tear-off portion 6 onto the first protective sub-layer 31 falls into the projection of the extension portion 352 onto the first protective sub-layer 31.

[0035] In this embodiment, a second operating portion 36 is formed by extending each protective sublayer at least one end of the protective film outward. Simultaneously, a second tear-off portion 6 is provided as a marker on the surface of the fourth protective sublayer 35 away from the third protective sublayer 34, corresponding to the extension 352 of the first operating portion 36. For example, a second tear-off portion with a prominent color is provided for easy identification and operation. Furthermore, to improve the adhesion between the second tear-off portion 6 and the protective film, the second tear-off portion 6 is a single-sided adhesive, with the adhesive side directly attached to the surface of the fourth protective sublayer 35 away from the third protective sublayer 34. When assembling the entire machine, the entire protective film can be removed in one go using the second tear-off portion 6, the extended portion 352, and the second operating portion 36, effectively improving the operability of the protective film.

[0036] In an optional embodiment, the thickness of the first protective sublayer is greater than the thickness of the light-shielding tape.

[0037] In this embodiment, by setting a first protective sub-layer with a thickness greater than that of the light-shielding tape, the overall structural rigidity of the protective film is effectively improved, ensuring that the protective film is not prone to denting or deformation during the transportation of the display panel, and can stably isolate external dust and debris.

[0038] Based on the display panel of the above embodiments, one embodiment of the present invention also provides a display device, including a display panel with the protective film removed.

[0039] The protective film on the display panel in the above embodiment ensures a high level of cleanliness in the camera area. The substrate surface of the display panel is free of foreign objects and dirt, ensuring that the camera's light-transmitting hole can clearly capture external light, effectively improving the camera module's light-gathering performance. During the assembly of the display device, the protective film is removed via a peel-off part, allowing assembly with other components. This ensures the cleanliness of the camera area before assembly, preventing foreign objects from affecting camera operation. The display device in this embodiment includes the display panel described in the above embodiment. The display device can be any product or component with a display function, such as a smartphone, tablet, television, monitor, laptop, digital photo frame, or navigator; this embodiment does not limit its application to this.

[0040] This invention addresses existing problems by providing a display panel and display device. It utilizes a protective film with a composite layer to protect semi-open light-shielding tape. On one hand, a protective sub-layer of the protective film compensates for the unclosed portion of the semi-open light-shielding tape; on the other hand, another protective sub-layer covers the camera area where the camera's light-transmitting hole is located. This compensates for the unclosed portion by using the protective sub-layer and protects the entire camera area from foreign objects entering, thus overcoming the problems in existing technologies, effectively improving the performance of the camera module, and consequently increasing the product yield of the display device. It has practical application value.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
