Apparently, the described embodiments are merely certain embodiments of the present disclosure, rather than all of the embodiments. All of the other embodiments that a person skilled in the art obtains on the basis of the embodiments of the present disclosure without paying creative work fall within the protection scope of the present disclosure.
In the related art, as shown in
In order to solve the above problem, the present disclosure provides a displaying module. Referring to
The adhering layer 22 is disposed between the shadow surface of the liquid-crystal display panel 21 and the optical film 23, and is configured for adhesively bonding the liquid-crystal display panel 21 and the optical film 23.
The orthographic projection of the adhering layer 22 on the liquid crystal display panel 21 covers at least the active area of the liquid-crystal display panel 21, and the orthographic projection of the optical film 23 on the liquid-crystal display panel 21 covers at least the active area of the liquid crystal display panel 21.
The shadow surface of the liquid crystal display panel 21 is the light-incoming surface of the liquid crystal display panel 21, i.e., the surface of the liquid-crystal display panel 21 at the side away from the light-exiting surface. In a particular implementation, the backlight firstly passes through the optical film 23 and the adhering layer 22, and subsequently enters the liquid-crystal display panel 21.
As an example, the adhering layer 22 may include an optical adhesive such as an ultraviolet rays (UV) adhesive, an optical clear resin (OCR) adhesive, an optically clear adhesive (OCA) adhesive and a poval environmental protection (PVA) adhesive, which is not limited in the present disclosure.
As an example, the optical film 23 may include optical filmi layers such as a light diffusing layer, a prism layer and a brightness enhancing film, which is not limited in the present disclosure.
As shown in
In the displaying module according to the present disclosure, because the liquid-crystal display panel 21 and the optical film 23 are fully adhered by using the adhering layer 22, the liquid-crystal display panel 21 can serve as the bearing plate of the optical film 23, and the optical film 23 no longer requires the glass diffuser plate to serve as the bearing plate, whereby no middle frame is required to serve as the carrier of the glass diffuser plate. As shown in
Because in the displaying module according to the present disclosure the glass diffuser plate and the middle frame can be omitted, the optical efficiency can be increased by at least 10%, to increase the luminous efficiency, and reduce the power consumption and the cost of the displaying module, whereby the displaying module is lighter and thinner. The no-middle-frame design can thoroughly eliminate the hidden trouble that the middle frame might shield the displayed frame, and solve the problems of the middle frame of the extremely-narrow-border-frame displaying modules with a complicated design, a tedious fabricating process, and a high difficulty and a low efficiency in the module assembling.
Optionally, the edge of the liquid crystal display panel 21, the edge of the adhering layer 22 and the edge of the optical film 23 flush, as shown in
Because the optical film 23 can homogenize and weaken the backlight-source light rays. when all of the edges of the adhering layer 22 and the optical film 23 flush with the edge of the liquid-crystal display panel 21, the light rays that have passed through and been weaken by the optical film 23 subsequently pass through the non-active area of the liquid-crystal display panel 21, which can greatly lower the degrees of the light leakage at the front surface and the lateral side surface of the liquid-crystal display panel 21, to reduce the edge light leakage.
In order to realize light convergence or light diffusion, the optical film 23 is usually provided with periodic microstructures. After the optical film 23 having the periodic microstructures and the liquid crystal display panel 21 are fully adhered, when light rays pass through the optical film 23 having the periodic microstructures and subsequently pass through the pixel structures periodically arranged in the liquid crystal display panel 21, resulting in occurring the light interference, and accordingly generating the rainbow fringe shown in
The inventor has found that, by adhering a specially designed polarizer (for example, a polarizer whose haze value is 55%) to the surface of the liquid crystal display panel 21, the rainbow fringe can be eliminated. However, such a specially designed polarizer has a very high price.
In order to eliminate the rainbow fringe, in an alternative implementation, the adhering layer 22 is an atomized adhering layer 22. Referring to
In a particular implementation, the atomized adhering layer 22 may also be another film layer that can scatter the incident light rays and has the property of adhesive bonding, which is not limited in the present disclosure.
Because the atomized adhering layer 22 can scatter the incident light rays, it can break up the light rays with a regularity exiting from the optical film 23. Accordingly, the lights entering the liquid crystal display screen become irregular scattered lights, and the irregular scattered lights, when passing through the pixel structures periodically arranged, do not have light interference. Therefore, the rainbow fringe can be eliminated, and, especially, the rainbow fringe is eliminated before the light rays entering the liquid crystal display panel 21.
Additionally, by disposing the adhering layer 22 as the atomized adhering layer 22 to eliminate the rainbow fringe, as compared with the solution in which a specially designed polarizer is adhered, the cost can be reduced.
The adhesive layer in the atomized adhering layer 22 may include one or more types of optical adhesives such as an UV adhesive, an OCR adhesive, an OCA adhesive and a PVA adhesive.
The diffusing particles in the atomized adhering layer 22 may include one or more types of organic particles such as polyolefin, polystyrene, polyamide, polyurethane and melamine, and may also include one or more types of inorganic particles such as silicon, silicon oxide, titanium oxide, aluminium oxide and zirconium oxide, which is not limited in the present disclosure.
The thickness of the atomized adhering layer 22 may be determined according to the particular type of the adhesive layer. For example, when the adhesive layer is an OCA sheet-material adhesive, the range of the thickness of the atomized adhering layer 22 may be 50 μm-300 μm. When the adhesive layer is an OCR water glue, the range of the thickness of the atomized adhering layer 22 may be 25 μm-150 μm. When the adhesive layer is a PVA adhesive, the range of the thickness of the atomized adhering layer 22 may be 20 μm-100 μm. When the adhesive layer is an UV water glue, the range of the thickness of the atomized adhering layer 22 may be 20 μm-100 μm.
Optionally, the haze value of the atomized adhering layer 22 may be larger than or equal to 60%. When the haze value of the atomized adhering layer 22 may be larger than or equal to 60%, that can thoroughly eliminate the rainbow fringe, improve the effect of displaying of the displaying module, and improve the frame quality.
In a particular implementation, the haze value of the atomized adhering layer 22 may be controlled by the proportion of the diffusing particles filled into the adhesive layer.
When the displaying module employs direct-type backlight sources and the light sources are periodically regularly arranged, because in the displaying module according to the present disclosure the glass diffuser plate is omitted, and the light rays, without being scattered by the glass diffuser plate, directly enter the optical film 23 and pass through the periodic microstructures in the optical film 23, light interference occurs, thereby generating a diamond-fringe imperfect. If the optical film 23 includes a single prism layer, a horizontal diamond fringe is generated, and if the optical filmi 23 includes double prism layers, a net-like diamond fringe is generated, as shown in
The inventor has found that, by configuring that the adhering layer 22 is the atomized adhering layer 22, the diamond-fringe imperfect can be ameliorated. However, in order to eliminate the diamond fringe, the haze value of the atomized adhering layer 22 is required to be larger than or equal to 95%. However, an excessively high haze value of the atomized adhering layer 22 might result in an adhesion imperfect.
In order to eliminate the diamond fringe, in an alternative implementation, as shown in
Because the first light diffusing layer 51 can scatter the incident light rays, by disposing the first light diffusing layer 51 in the optical film 23, the light rays coming from the backlight sources periodically regularly arranged can be scattered, and the irregular scattered lights, when passing through the periodic microstructures in the optical film 23, do not have light interference, which can eliminate the diamond fringe.
Optionally, the haze value of the first light diffusing layer 51 is larger than or equal to 75%. When the haze value of the first light diffusing layer 51 is larger than or equal to 75%, the diamond fringe can be thoroughly eliminated.
As an example, as shown in
Optionally, the haze value of the first atomizing-particle layer 511 may be larger than or equal to 75%.
In the present example, the first atomizing-particle layer 511 may be fabricated by spray-coating the diffusing particles onto the surface of the first matrix layer 512.
In a particular implementation, the first light diffusing layer 51 may also be fabricated by filling the diffusing particles into a matrix (for example, polyethylene glycol terephthalate), and the corresponding first light diffusing layer 51 is a conventional diffusion sheet structure.
In order to further increase the degree of the lightness and thinness of the displaying module, to reduce the load of the liquid crystal display panel 21, the primary material of the first matrix layer 512 may be a polymer resin, for example, polyethylene glycol terephthalate (PET), which is not limited in the present disclosure.
Optionally, as shown in
As an example, as shown in
In the present example, the second atomizing-particle layer 551 may be fabricated by spray-coating the diffusing particles onto the surface of the second matrix layer 552.
In a particular implementation, the second light diffusing layer 55 may also be fabricated by filling the diffusing particles into a matrix (for example, polyethylene glycol terephthalate), and the corresponding second light diffusing layer 55 is a conventional diffusion sheet structure.
In order to further increase the degree of the lightness and thinness of the displaying module, to reduce the load of the liquid crystal display panel 21, the primary material of the second matrix layer 552 may be a polymer resin, for example, PET, which is not limited in the present disclosure.
Optionally, as shown in
As shown in
It should be noted that the included angle between the extending direction of the first prism columns 61 and the extending direction of the second prism columns 62 may also be other angles that are larger than 0° and less than 180°, which is not limited in the present disclosure.
Referring to
The brightness enhancing film 54 is a thin film or thin sheet that can increase the utilization ratio of the light rays, and may particularly be a prismatic lens, a micro-prismatic lens, a reflection-type polarizer and so on, which is not limited in the present disclosure.
The optical film 23 may, according to practical demands, be selectively provided with one or more optical film layers such as the first light diffusing layer 51, the first prism layer 52, the second prism layer 53, the brightness enhancing film 54 and the second light diffusing layer 55, which is not limited in the present disclosure.
In a particular implementation, the optical fib 23 may also include an adhesive layer (not shown in the drawings) disposed between two neighboring film layers.
In order to further increase the degree of the lightness and thinness of the displaying module, in an alternative implementation, at least one of the film layers included by the optical film 23 forms a composite film together with the adhering layer 22; and/or
The composite film refers to two or more optical film layers that are integrated into one film layer. Therefore, by using the composite film, the adhering process can be simplified.
Optionally, at least two of the film layers included by the optical filmi 23 may form the composite film.
For example, the optical film 23 may include one or more of the following composite films: (1) a composite film formed by the first prism layer 52, the second prism layer 53 and the brightness enhancing film 54, for example, the composite film 102 shown in

The inventor has found that, because the black matrix at the edge of the extremely-narrow-border-frame screen has a very low width, which is usually less than 1 mm, the black matrix cannot completely shield the edge light leakage, which results in a serious edge light leakage of the liquid crystal display panel 21, as shown in
In order to solve the problem of edge light leakage, in an alternative implementation, as shown in
By disposing the light shielding layer 142 at the periphery of the fully adhered structure 141, the edge light leakage can be blocked, to eliminate the light leakage in the extremely-narrow-border-frame display screen caused by the low width of the black matrix.

That can ensure that the supporting platform 143 does not shield the active area.
