Description

Technical Field

[0001] This utility model relates to the field of display device technology, specifically to a film layer structure and a display device having the same. Background Technology

[0002] With the widespread use of in-vehicle infotainment screens, mobile phones, tablets, and other electronic products, users have higher requirements for the overall aesthetics of the screen when it is off. Currently, such as Figure 1 As shown, the glass cover of such products typically consists of a light-transmitting visible area and a surrounding opaque ink area. When the screen is off, there is a significant color difference between the visible area and the ink area, reducing the product's aesthetics and user experience. Current technology involves coating the glass cover with an AR layer, but the seamless black effect when the screen is off and the display quality when the screen is on still require improvement. Utility Model Content

The two AR layers significantly reduce the strong reflected light of ambient light on the outer surface of the transparent substrate. Thus, by using the grayscale component layer 4 and the two AR layers simultaneously, the reflection problem at different levels is solved. The complementary internal absorption and surface interference make the visible area darker when the screen is off, improving the overall black effect, while the displayed content is also clearer when the screen is on.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] According to an embodiment of this utility model, in one aspect, a film layer structure is provided, disposed on the display screen of an optical display device, to improve the seamless black effect when the screen is off without affecting the screen display quality. For example... Figure 2As shown, the film structure includes a transparent substrate 1, a grayscale component layer 4, a first AR layer 2, and a second AR layer 3. The transparent substrate 1 can be made of a material with good light transmittance, such as glass, acrylic, or composite materials. In this embodiment, a glass cover plate is used as the transparent substrate 1. The transparent substrate 1, the grayscale component layer 4, and the first AR layer 2 are stacked sequentially; the second AR layer 3 is disposed on the side of the transparent substrate 1 opposite to the first AR layer 2, or the second AR layer 3 and the first AR layer 2 are disposed on the same side of the transparent substrate 1 but not adjacent to each other. In this embodiment, the grayscale component layer 4 can be located on the front or back of the transparent substrate 1.

[0025] In this film structure, the grayscale component layer is coated on the entire visible area of ​​the transparent substrate, deepening the color of the visible area and reducing the reflected light on the inner side of the transparent substrate (the side closer to the display screen) under ambient light when the screen is off. It can also absorb the light transmitted through the transparent substrate 1, making the visible area appear darker, thereby improving the overall black effect. The AR layer includes two layers: a first AR layer and a second AR layer. The two AR layers significantly reduce the strong reflected light of ambient light on the outer surface of the transparent substrate. Thus, by using the grayscale component layer 4 and the two AR layers simultaneously, the reflection problem at different levels is solved. The complementary internal absorption and surface interference make the visible area darker when the screen is off, improving the overall black effect, while the displayed content is also clearer when the screen is on.

[0026] It should be noted that simply using a grayscale component layer to deepen the color of the visible area will darken the screen when it is on, thus increasing the power consumption required to turn on the screen. This film structure reduces the screen's inherent brightness when it is off through the grayscale component layer, and eliminates ambient light reflection from the screen's outer surface through a dual-layer AR layer, improving the overall black level when the screen is off and the display quality when the screen is on. The two work together to enhance the overall black level effect.

[0027] In one embodiment, please refer to Figures 3A to 3C The grayscale component layer 4 includes a grayscale optical adhesive layer 4-1 and a transparent explosion-proof film layer 4-2. The grayscale optical adhesive layer 4-1 is located on the side of the transparent explosion-proof film layer 4-2 that is close to the transparent substrate 1.

[0028] When the first AR layer 2 and the second AR layer 3 are disposed on the same side of the transparent substrate 1, the grayscale component layer is disposed between the first AR layer 2 and the second AR layer 3; when the first AR layer 2 and the second AR layer 3 are respectively disposed on both sides of the transparent substrate 1, the grayscale component layer is disposed between the first AR layer 2 and the transparent substrate 1.

[0029] A grayscale optical adhesive layer 4-1 adheres the transparent explosion-proof film layer 4-2 to the transparent substrate 1. The transparent explosion-proof film layer 4-2 provides basic support and enhances the overall impact resistance of the film structure, thereby improving the overall explosion-proof performance of the film structure. Furthermore, the first AR layer 2 is disposed on the transparent explosion-proof film layer 4-2, which improves adhesion and avoids the film peeling problem that may occur when the AR layer is directly deposited on the glass.

[0030] Preferably, the first AR layer 2 and the second AR layer 3 are respectively disposed on both sides of the transparent substrate 1. For example, the first AR layer 2 is disposed on the back side of the transparent substrate 1, that is, the side close to the display screen, and the second AR layer 3 is disposed on the front side of the transparent substrate, that is, the side away from the display screen. As a result, the reflection of ambient light when it reaches the air-glass interface on the outside of the transparent substrate 1 is weakened, and the reflection of light when it reaches the glass-grayscale component layer interface on the inside of the transparent substrate 1 is also weakened. This can minimize the light reflection on both sides of the glass, so that ambient light can pass through the glass and the grayscale component layer to the maximum extent, and then be absorbed by the grayscale component layer and the display screen at the bottom, so that the human eye can hardly receive obvious reflected light, making the glass more "hollow", thereby achieving an ultimate all-in-one black effect.

[0031] Furthermore, when the second AR layer 3 is disposed on the side of the transparent substrate 1 facing away from the first AR layer 2, a transparent reinforcing component layer 5 is also disposed between the transparent substrate 1 and the second AR layer 3. The reinforcing component layer 5 includes a reinforcing optical adhesive layer 5-1 and a reinforcing explosion-proof film layer 5-2. The reinforcing optical adhesive layer 5-1 is disposed on the side of the reinforcing explosion-proof film layer 5-2 close to the transparent substrate 1.

[0032] The reinforced explosion-proof film layer 5-2 is bonded to the transparent substrate 1 via the reinforced optical adhesive layer 5-1, and the second AR layer 3 is deposited on the reinforced explosion-proof film layer 5-2. The reinforced component layer also provides a flat and firm adhesion substrate for the second AR layer 3, which can prevent the second AR layer 3 from falling off due to unevenness caused by the ink area on the back edge of the transparent substrate 1, and further enhance the adhesion of the second AR layer.

[0033] In summary, referring to Figures 3A to 3C When the grayscale component layer 4 uses a grayscale optical adhesive layer 4-1 and a transparent explosion-proof film layer 4-2, the film structure can have the following forms: From the front side to the back side or from the back side to the front side, the components are as follows: first AR layer 2, transparent explosion-proof film layer 4-2, grayscale optical adhesive layer 4-1, transparent substrate 1, and second AR layer 3. From the front side to the back side or from the back side to the front side, the layers are as follows: first AR layer 2, transparent explosion-proof film layer 4-2, grayscale optical adhesive layer 4-1, transparent substrate 1, transparent reinforced optical adhesive layer 5-1, transparent reinforced explosion-proof film layer 5-2, and second AR layer 3. From the front side to the back side or from the back side to the front side, the layers are as follows: first AR layer 2, transparent explosion-proof film layer 4-2, grayscale optical adhesive layer 4-1, second AR layer 3, and transparent substrate 1.

[0034] In the above film structure, the dual-layer AR layer solves the light reflection problem at the source, and the grayscale component layer 4 absorbs the light that has already passed through through the grayscale optical adhesive layer 4-1. The two work together to minimize light reflection and maximize light absorption, thereby achieving a better integrated black effect and ensuring the display quality when the screen is on.

[0035] In another embodiment, please refer to Figures 4A to 4C The grayscale component layer 4' includes a transparent optical adhesive layer 4'-1 and a grayscale explosion-proof film layer 4'-2. The transparent optical adhesive layer 4'-1 is located on the side of the grayscale explosion-proof film layer 4'-2 that is close to the transparent substrate 1.

[0036] like Figure 4C When the first AR layer 2 and the second AR layer 3 are disposed on the same side of the transparent substrate 1, the second AR layer 3 is formed on the transparent substrate 1, and the grayscale component layer 4' is disposed between the first AR layer 2 and the second AR layer 3; as Figure 4A When the first AR layer 2 and the second AR layer 3 are disposed on different sides of the transparent substrate 1, the grayscale component layer 4' is disposed between the first AR layer 2 and the transparent substrate 1.

[0037] The grayscale component layer 4' consists of a transparent optical adhesive layer 4'-1 and a grayscale explosion-proof film layer 4'-2. Unlike the previous embodiment, this grayscale component layer 4' absorbs transmitted light through the gray or black pigment of the grayscale explosion-proof film layer 4'-2. This embodiment has the same beneficial effects as the embodiments described above.

[0038] Furthermore, such as Figure 4B When the second AR layer 3 is disposed on the side of the transparent substrate 1 opposite to the first AR layer 2, a transparent reinforcing component layer is disposed between the transparent substrate 1 and the second AR layer 3. The reinforcing component layer 5' includes a reinforcing optical adhesive layer 5'-1 and a reinforcing explosion-proof film layer 5'-2. The reinforcing optical adhesive layer 5'-1 is disposed on the side of the reinforcing explosion-proof film layer 5'-2 close to the transparent substrate 1.

[0039] In summary, when the grayscale component layer 4' adopts a transparent optical adhesive layer 4'-1 and a grayscale explosion-proof film layer 4'-2, the film structure can have the following forms: From the front side to the back side or from the back side to the front side, the layers are arranged in sequence as follows: first AR layer 2, grayscale explosion-proof film layer 4'-2, transparent optical adhesive layer 4'-1, transparent substrate 1, and second AR layer 3. From the front side to the back side or from the back side to the front side, the layers are arranged in sequence as follows: first AR layer 2, grayscale explosion-proof film layer 4'-2, transparent optical adhesive layer 4'-1, transparent substrate 1, transparent reinforced optical adhesive layer 5'-1, transparent reinforced explosion-proof film layer 5'-2, and second AR layer 3. From the front side to the back side or from the back side to the front side, the layers are arranged in sequence as follows: first AR layer 2, grayscale explosion-proof film layer 4'-2, transparent optical adhesive layer 4'-1, second AR layer 3, and transparent substrate 1.

[0040] In the above film structure, the dual-layer AR layer solves the light reflection problem at the source, and the gray component layer 4 absorbs the light that has already passed through through the gray explosion-proof film layer 4'-2. The two work together to minimize light reflection and maximize light absorption, thereby achieving a better integrated black effect and ensuring the display quality when the screen is on.

[0041] The grayscale explosion-proof film layer 4'-2 is set on the front or back of the transparent substrate 1 of the seat to improve the overall black effect by absorbing light. Therefore, it is only necessary to set the grayscale explosion-proof film on either side of the glass cover.

[0042] In another embodiment, reference is made to Figures 5A to 5C The grayscale component layer 4'' can also be a semi-transparent ink layer, that is, the pigment in the ink absorbs the light that has been transmitted. The second AR layer 3 is disposed on the side of the transparent substrate 1 that is away from the first AR layer 2.

[0043] Furthermore, a reinforcing component layer 5'' is provided on one or both sides of the transparent substrate 1. The reinforcing component layer 5'' includes a transparent reinforcing optical adhesive layer 5''-1 and a reinforcing explosion-proof film layer 5''-2. The reinforcing optical adhesive layer 5''-1 is located on the side of the reinforcing explosion-proof film layer 5''-2 closest to the transparent substrate 1. By providing reinforcing component layers on one or both sides of the transparent substrate 1, each reinforcing component layer includes a reinforcing optical adhesive layer 5''-1 and a reinforcing explosion-proof film layer 5''-2. The reinforcing optical adhesive layer 5''-1 is always located between the reinforcing explosion-proof film layer 5''-2 and the transparent substrate 1, serving an adhesive function. By providing reinforcing component layers on one or both sides of the transparent substrate 1 as needed, the explosion-proof performance and AR coating adhesion of specific locations or the overall product can be specifically improved.

[0044] In another embodiment, reference is made to Figure 5D When the grayscale component layer 4'' is a semi-transparent ink layer, the second AR layer 3 can also be disposed on the same side of the transparent substrate 1 as the first AR layer 2. In this case, a transparent reinforcing component layer 5'' is disposed between the first AR layer 2 and the second AR layer 3. The reinforcing component layer 5'' includes a reinforcing optical adhesive layer 5''-1 and a reinforcing explosion-proof film layer 5''-2. The reinforcing optical adhesive layer 5''-1 is located on the side of the reinforcing explosion-proof film layer 5''-2 that is close to the transparent substrate 1.

[0045] By placing both the first AR layer 2 and the second AR layer 3 on the same side of the transparent substrate 1 and inserting a transparent reinforcing component layer between the first AR layer 2 and the second AR layer 3, light reflection can be reduced, and combined with light absorption, the overall black effect of the display panel can be enhanced.

[0046] In summary, when the grayscale component layer 4'' uses a semi-transparent ink layer, the film structure can take the following forms: From the front side to the back side or from the back side to the front side, the components are: first AR layer 2, semi-transparent ink layer, transparent substrate 1, and second AR layer 3; From the front side to the back side or from the back side to the front side, the layers are as follows: first AR layer 2, transparent reinforced explosion-proof film layer 5''-1, transparent reinforced optical adhesive layer 5''-2, translucent ink layer, transparent substrate 1, and second AR layer 3. From the front side to the back side or from the back side to the front side, the layers are as follows: first AR layer 2, transparent reinforced explosion-proof film layer 5''-2, transparent reinforced optical adhesive layer 5''-1, translucent ink layer, transparent substrate 1, another transparent reinforced optical adhesive layer 5''-1, another transparent reinforced explosion-proof film layer 5''-2, and second AR layer 3. The layers arranged sequentially from front to back or back to front are: a first AR layer 2, a transparent reinforced explosion-proof film layer 5''-2, a transparent reinforced optical adhesive layer 5''-1, a second AR layer 3, a translucent ink layer, and a transparent substrate 1. In one embodiment, an AG layer 6 is disposed between the grayscale component layer and the first AR layer 2. The AG layer 6 can transform strong specular reflection into soft diffuse reflection, effectively reducing ambient light interference and improving visibility in strong light environments, while not affecting the main optical effects of monochromatic black and anti-reflection.

[0047] In one embodiment, please refer to Figure 2 An AF layer 7 is provided on the side of the first AR layer 2 facing away from the transparent substrate 1. The AF layer 7 gives the outer surface of the first AR layer 2 oleophobic and hydrophobic properties, which can effectively prevent the adhesion of fingerprints and oil stains, keep the screen clean, and at the same time improve the surface hardness and scratch resistance.

[0048] In one embodiment, an HC layer is disposed between the side of the grayscale component layer facing away from the transparent substrate 1 and the first AR layer 2. The HC layer can enhance the adhesion between the first AR layer 2 and the underlying structure, reduce the occurrence of film peeling, and improve the reliability of the product in long-term use.

[0049] The aforementioned reinforced optical adhesive layer or transparent optical adhesive layer uses optical adhesives with a light transmittance of over 94%. The grayscale optical adhesive layer uses smoked optical adhesive, which has lower light transmittance and is manufactured using processes such as smoking. Both the first AR layer 2 and the second AR layer 3 are antireflective films, utilizing the principle of light interference to reduce strong reflection of ambient light on the visible surface and improve transmittance. The AG layer 6 is a diffuse reflection layer, which alters the microstructure of the optical element surface through etching and other methods. The AG layer 6 can convert specular reflection into diffuse reflection, thus reflecting light instead of it directly entering the eye, thereby reducing glare interference. The AF layer 7 is an anti-fingerprint layer, which reduces the adhesion of fingerprint grease and increases hardness. A transparent or reinforced explosion-proof film is applied to the surface of the glass cover to improve its explosion-proof capability and prevent shattering after impact. It can be made of cellulose triacetate (TAC) or polyethylene terephthalate (PET). The gray-scale explosion-proof film layer is a semi-transparent explosion-proof film made by dyeing a transparent explosion-proof film. The HC layer is a hardened coating that enhances the adhesion of the coating.

[0050] Secondly, this utility model also provides a display device, including a device body, wherein the display window of the device body is provided with the film layer structure described in any of the above claims. The display device can be any device with a display screen, such as a mobile phone, tablet computer, smartwatch, vehicle display screen, or smart home display panel. By setting a grayscale component layer, a first AR layer 2, and a second AR layer 3 within the thin film, the display quality in the screen-on state is improved, and the visually unified black effect in the screen-off state is enhanced, thereby improving the product's appearance quality and user experience.

[0051] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
