Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the invention provides a display device 100. The display device 100 includes: the backlight module comprises a shielding frame 101, a nickel-plated structure 102, a backlight hole 103, a reflective film layer 104, a light guide plate 105, a diffusion film layer 106, a first optical film layer 107, a second optical film layer 108, a light shielding tape layer 109, a lower polarizer 110, an array substrate 111, a color film substrate 112, an upper polarizer 113, an adhesive 114 and a glass cover plate 115.
In order to solve the problem of poor front bright lines of blind holes (i.e. backlight holes) of the liquid crystal display panel, that is, the problem of bright fixed positions caused by light gathering in front of the holes (i.e. backlight holes or blind holes), a diffusion silk-screen black ink may be coated on the surface of the diffusion film 106, and a nickel plating structure 102 (light absorbing part) is disposed on the inner surface of the shadow frame 101. When light is gathered in front of the blind hole, the black nickel plating structure 102 and the black diffusion silk-screen printing ink on the shielding frame can absorb part of the light, so that the light energy in front of the blind hole is reduced, the brightness of the light can be further reduced so as to homogenize the luminance in front of the blind hole, the light gathering in front of the blind hole can be reduced, and the purpose of solving the problem of bright lines in front of the hole is achieved.
The problem of poor bright lines in front of the holes can be solved by arranging the black nickel plating structure 102 on the shielding frame and coating the diffusion silk-screen black ink on the surface of the diffusion film layer 106. The process involved in this approach is complex and costly. Therefore, the present invention further proposes the following modifications.
As shown in fig. 2, an embodiment of the invention provides a backlight module 200. The backlight module 200 includes a shielding frame 201, a light absorbing portion 202, a backlight hole 203, a reflective film layer 204, a light guide plate 205, a diffusion film layer 206, a first optical film layer 207, a second optical film layer 208, and a light shielding tape layer 209.
In the embodiment of the invention, the problem of bright lines in front of the hole can be solved under the condition that the nickel plating structure is not added to the shielding frame 201. In the embodiment of the invention, a molding process is adopted to tightly combine the light absorbing part 202 and the shielding frame 201, wherein the light absorbing part 202 is black and has a triangular structure. When light passes through the light guide plate 205, the light enters the surface of the light absorbing part 202. Since black absorbs light, the energy of the light in front of the hole is reduced and the bright lines in front of the hole are weakened. The scheme saves cost, has simple process and can achieve the aim of solving the problem of bright lines in front of the hole.
In the embodiment of the present invention, the backlight module 200 is provided with a backlight hole 203. The shielding frame 201 includes a main body 2011 corresponding to the backlight module 200 except for the backlight hole 203, and a bending part 2012 surrounding the inner sidewall of the backlight hole 203. The shielding frame 201 is made of a metal polymer with high hardness and high toughness containing iron components, the bent portion 2012 is integrally formed with the main body portion 2011 or is mechanically connected to the main body portion 2011, and the mechanical connection includes mechanical connection through adhesive bonding, mechanical snap and the like.
The light absorbing portion 202 is attached to the side of the bending portion 2012 far away from the backlight hole 203, that is, the light absorbing portion 202 is attached to the inner side wall of the bending portion 2012. The material of the light absorbing part 202 includes a black high molecular polymer, which is a granular substance. The black high molecular polymer can convert the visible light entering the surface of the shielding frame 201 into other energy to reduce the light reflected by the surface of the shielding frame 201, so that the light reflected to a visible area is weakened, the brightness of the surface of the shielding frame 201 is reduced, and the bright line in front of the hole can be greatly weakened. Preferably, the light-absorbing portion 202 is a triangular structure. By adopting the triangular structure, not only can a narrow frame be realized, but also the light absorption area can be increased. When light is gathered in front of the holes of the light guide plate 205, the light absorption part of the black triangular structure can absorb the light reflected or refracted by the reflection film layer 204, so that the light energy in front of the holes is reduced, and the light gathering in front of the holes is reduced, so that the light energy can be uniformly distributed, and the effect of uniform picture display is achieved. In some embodiments, the bent portion 2012 and the light absorbing portion 202 are formed by injection molding, and the bent portion 2012 and the light absorbing portion 202 are fused at a high temperature and are injected by a molding machine, so that the light absorbing portion 202 is tightly combined with the bent portion 2012 of the shielding frame 201. In some embodiments, the side of the bent portion 2012 joined to the light absorbing portion 202 is provided with a hole structure for better engaging with the light absorbing portion 202 of the particulate matter.
The height of the light absorbing part 202 is the sum of the heights of the light guide plate 205 and the reflective film layer 204. When the height of the light absorbing part 202 is too high, the light absorbing part 202 interferes with other components above the light guide plate 205; when the height of the light absorbing part 202 is too low, the light absorbing part 202 cannot maximally absorb the light at that position, so that the maximum improvement cannot be achieved. In addition, the light absorbent portion 202 may have a variety of configurations, as particularly shown in FIGS. 3a-3 c. When the height of the backlight module is low and the backlight hole frame is wide, the light absorbing part shown in fig. 3a may be used. When the height of the backlight module is low and the backlight hole frame is wide, the light absorbing part shown in fig. 3b can be adopted (the adhesive surface of the upper side and the adhesive tape can be added on the basis of fig. 3 a). When the height of the backlight module is high and the backlight hole frame is narrow, the light absorbing part shown in fig. 3c may be used.
Referring to fig. 2, in the present embodiment, the reflective film 204 is disposed on the main body 2012.
The light guide plate 205 is disposed on the reflective film layer 204. The light guide plate 205 is generally made of an acrylic material, so that a linear light source emitted from the light source is refracted to be a surface light source, which is helpful for improving the light emitting efficiency. If the backlight module 200 is an edge-type backlight module, the leds are disposed at an end of one side of the light guide plate 205 to provide light to the light guide plate 205. The backlight light emitted from the leds passes through the dots in the light guide plate 205 and then exits through the edge surface of the light guide plate 205. The emitted light propagates through the air and irradiates the surface of the shielding frame 201. Because the light-absorbing part 202 of the black high molecular polymer is arranged on the shielding frame 201, the light can be effectively absorbed, and the light cannot be reflected, so that the problem of bright lines before holes is avoided.
The diffusion film layer 206 is disposed on the light guide plate 205. The diffusion film layer 206 may improve a diffusion effect of uniform distribution of backlight light, and may improve light transmittance to improve brightness. The edge of the diffusion film 206 is coated with a black environmental-friendly polymer to avoid light leakage.
The first optical film layer 207 is disposed on the diffusion film layer 206. The first optical film layer 207 is a brightness enhancement film, which includes a prism, a diffusion film, etc., and has an effect of improving the optical performance of the backlight module.
The second optical film layer 208 is disposed on the first optical film layer 207. The second optical film layer 208 is a brightness enhancement film, which includes a prism, a diffusion film, etc., and has an effect of improving the optical performance of the backlight module.
The light-shielding tape layer 209 is disposed on the second optical film layer 208.

The display device 300 includes: the backlight module comprises a shielding frame 201, a light absorption portion 202, a backlight hole 203, a reflection film layer 204, a light guide plate 205, a diffusion film layer 206, a first optical film layer 207, a second optical film layer 208, a light shielding adhesive tape layer 209, a lower polarizer 210, an array substrate 211, a color film substrate 212, an upper polarizer 213, an adhesive 214 and a glass cover plate 215.
