Abstract
Description
Technical Field
[0001] The present application relates to the technical field of liquid crystal modules, and more specifically, to a liquid crystal module and a display device. Background Art
[0002] With the continuous development of electronic technology, liquid crystal display devices such as tablet computers are increasingly tending towards larger screens. For example, tablet computers have grown from 7 to 8 inches to 10.1 to 12 inches, and the screen size will continue to increase in the future.
[0003] Liquid crystal display devices all include liquid crystal display modules. Traditional liquid crystal display modules usually include a liquid crystal display screen and a backlight module. However, as more and more products now focus on screen-to-body ratio, many narrow-edge liquid crystal display modules have emerged. That is, liquid crystal display modules with the same visible size have smaller and smaller peripheral dimensions. There will be bright edges around the product's viewing area, and the overall visual effect is poor. Utility Model Content
[0004] The purpose of the embodiments of the present application is to provide a liquid crystal module and a display device that can effectively avoid the appearance of white edges around the edges and improve product quality.
[0005] In the first aspect, an embodiment of the present application provides a liquid crystal module, comprising: a plastic frame, comprising a frame body and a first boss, the first boss being connected to the frame body, and the side of the first boss facing away from the frame body being configured as a slope; a light guide plate being configured below the first boss, the side of the light guide plate close to the first boss being a light emitting surface, and the edge of the light guide plate being farther away from the center of the light guide plate at the slope.
[0006] In the above implementation process, the rubber frame is provided with a first boss, and one side of the first boss is set as a bevel, and the light guide plate is located below the first boss, so that the light coming out of the light-emitting surface of the light guide plate is refracted and dispersed in multiple directions through the bevel. Compared with the case where no bevel is made, the direction and range of light dispersion are larger. The light scattered by the bevel is subsequently refracted and dispersed for the second time, so that the light will not focus at the edge, thereby effectively avoiding the appearance of white edges around the liquid crystal module, thereby improving the quality of the product.
[0007] In some embodiments, the angle between the inclined surface and the light-emitting surface is 135° to 150°, which helps the light emitted from the light-emitting surface of the light guide plate to be refracted and dispersed in multiple directions, effectively avoiding the appearance of white edges around the edges, and improving product quality and display effects.
[0008] In some embodiments, the length of the first protrusion is not less than 0.3 mm, which can effectively avoid the appearance of white edges around the liquid crystal module, improve product quality, and meet the requirements of the update and iteration of narrow-edge products.
[0009] In some embodiments, the width of the bevel is not less than 0.3 mm, which can effectively avoid the appearance of white edges around the liquid crystal module, improve product quality, and meet the update and iteration requirements of narrow-edge products.
[0010] In some embodiments, the liquid crystal module further includes an optical film material, which is disposed on a side of the first boss facing away from the light guide plate, and a gap is disposed between the optical film material and the light guide plate.
[0011] In the above-mentioned implementation process, the optical film material is supported by the first boss, so that the light coming out of the light-emitting surface of the light guide plate is refracted and dispersed in multiple directions through the inclined surface of the first boss. Compared with the case where no bevel is made, the direction and range of the light dispersion are larger. The light scattered by the inclined surface is refracted and dispersed again by the optical film material, so that the light will not be focused at the edge, thereby effectively avoiding the appearance of white edges around the liquid crystal module and improving the quality of the product.
[0012] In some embodiments, the liquid crystal module further includes a reflective film, and the reflective film is disposed on a side of the light guide plate away from the light emitting surface.
[0013] In the above implementation process, the reflective film can reflect the light onto the light guide plate, diffuse it to the light exiting surface of the light guide plate, and emit it from the light exiting surface of the light guide plate, which can ensure that the light is more uniform and reduce the phenomenon of uneven light caused by the light from the side of the light guide plate away from the light exiting surface unable to pass through the light guide plate again.
[0014] In some embodiments, the liquid crystal module further includes a FOG, and the FOG contacts a side of the optical film material facing away from the first boss.
[0015] In some embodiments, the frame is further configured with a second boss, the second boss is closer to the outer edge of the frame than the first boss, and the side of the second boss facing away from the light guide plate is used to contact the FOG.
[0016] In some embodiments, the liquid crystal module further includes an iron frame, and the iron frame is configured to fix the plastic frame and the light guide plate.
[0017] In a second aspect, the present application further provides a display device comprising a liquid crystal module as described in any one of the above items.
[0018] Since the display device provided in the second aspect includes a liquid crystal module, the display device has all the technical effects of the liquid crystal module, which will not be described in detail here.
[0019] Other features and advantages of the present disclosure will be set forth in the following description, or some features and advantages may be inferred or unambiguously determined from the description, or may be learned by practicing the above-mentioned technology of the present disclosure.

[0031] Example
[0032] Liquid crystal modules (LCDs) consist primarily of a screen and backlight assembly. These two components are assembled together but operate independently (i.e., their circuits are unrelated). LCDs primarily provide image display functionality and are widely used in various electronic products, including mobile phones, tablets, televisions, and e-books. They offer advantages such as small size, light weight, low power consumption, and excellent display quality, making them one of the most common display technologies currently available.
[0033] The backlight module (also known as the backlight source) is a light source located behind the LCD. Its luminous efficiency directly affects the visual quality of the LCD module. It is primarily composed of a light source, a light guide plate, an optical film, and a plastic frame. It features high brightness, a long lifespan, and uniform light emission.
[0034] LCDs are non-luminous display devices that require a backlight module to function. The performance of the backlight module directly affects the LCD's image quality.
[0035] During the design process, the inventor discovered that the backlight module assembly structure currently on the market, as more and more products now focus on screen-to-body ratio, has led to the emergence of many narrow-edge LCDs, that is, LCDs with the same visible size, but with smaller and smaller outer dimensions, will have bright edges around the product's viewing area (that is, when viewed from the side of the liquid crystal module, a very bright light will be generated at the edge between the LCD and the backlight module). To solve the bright edge problem, there are currently two solutions: 1. Add a piece of black light-shielding glue, but the material cost and labor cost will increase, reducing production efficiency; 2. Use a black glue frame instead of a black glue frame, but under the same conditions, the product brightness will be reduced, which will increase the product cost while ensuring the brightness.
[0036] like Figure 1-Figure 2 As shown, in the first aspect, an embodiment of the present application provides a liquid crystal module 10, comprising: a plastic frame 101, comprising a frame body 1011 and a first boss, wherein the first boss is connected to the frame body 1011, and the side of the first boss facing away from the frame body 1011 is configured as a slope 1012; a light guide plate 102, which is configured below the first boss, and the side of the light guide plate 102 close to the first boss is a light emitting surface, and the edge of the light guide plate 102 is farther away from the center of the light guide plate 102 at the slope 1012.
[0037] For example, when the width of the BL-AA and LCD-AA regions reaches 1.5mm or greater, no bright borders appear around the edges of the product. However, if the width is smaller than this, bright borders appear, and the smaller the width, the more pronounced they become. Currently, with product upgrades and the increasing number of narrow-bezel LCDs entering production, the width is shrinking. The improved solution of this application can eliminate bright borders even at a width of 0.8mm, thereby improving light energy utilization.
[0038] The conventional structure is that the optical film material is directly placed in the plastic frame (i.e., in the BL_A.A area) and contacts the light guide plate. In this structure, the light of the backlight module is guided out through the light-emitting surface of the light guide plate (the side of the light guide plate close to the optical film material is the light-emitting surface). The light hits the plastic frame and is reflected back to the edge of the optical film material. There is constant light reflection back and forth between the edge of the plastic frame and the edge of the optical film material, causing the light to gather between the two. If the spacing WIDTH between the BL_A.A area and the LCD_A.A area is not wide enough, it is easy to see a very bright line on the edge (i.e., the white edge mentioned in this application); in this application, the frame 1011 and the first boss can be fixed by one-piece molding technology, and the frame 1011 has the first boss added relative to the conventional structure, and one side of the first boss is configured as a slope 1012.
[0039] In the above implementation process, the plastic frame 101 is provided with a first boss, and one side of the first boss is set as a bevel 1012. The light guide plate 102 is located below the first boss, so that the light coming out of the light-emitting surface of the light guide plate 102 is refracted and dispersed in multiple directions through the bevel 1012. Compared with the case where no bevel is made, the direction and range of the light dispersion are larger. The light dispersed by the bevel 1012 is subsequently refracted and dispersed for the second time, so that the light will not focus at the edge, thereby effectively avoiding the appearance of white edges around the liquid crystal module 10, thereby improving the quality of the product.
[0040] In some embodiments, the angle between the inclined surface 1012 and the light-emitting surface is 135° to 150°. It should be noted that the angle can be 135°, 140°, 145°, 150°, etc. Of course, the inclination angle of the inclined surface 1012 can be adjusted according to the product structure, and will not be described in detail here. This is beneficial for refracting and dispersing light from the light-emitting surface of the light guide plate 102 in multiple directions, effectively avoiding the appearance of white edges around the edges, and improving product quality and display effects.
[0041] In some embodiments, the length of the first protrusion is not less than 0.3 mm, which can effectively avoid the appearance of white edges around the liquid crystal module 10, improve product quality, and meet the update and iteration requirements of narrow-edge products.
[0042] In some embodiments, the width of the inclined surface 1012 is not less than 0.3 mm, which can effectively avoid the appearance of white edges around the liquid crystal module 10, improve product quality, and meet the update and iteration requirements of narrow-edge products.
[0043] like Figure 2As shown, the liquid crystal module 10 also includes an optical film material 103, which is arranged on the side of the first boss away from the light guide plate 102, and a gap is arranged between the optical film material 103 and the light guide plate 102, wherein the optical film material 103 is supported by the first boss, and the optical film material 103 includes but is not limited to a diffusion or brightness enhancement film.
[0044] In the above-mentioned implementation process, the optical film material 103 is supported by the first boss, so that the light coming out of the light-emitting surface of the light guide plate 102 is refracted and dispersed in multiple directions through the inclined surface 1012 of the first boss. Compared with the case where no bevel is made, the direction and range of the light dispersion are larger. The light dispersed by the inclined surface 1012 is refracted and dispersed again by the optical film material 103, so that the light will not be focused at the edge, thereby effectively avoiding the appearance of white edges around the liquid crystal module 10, thereby improving the quality of the product.
[0045] In some embodiments, the liquid crystal module 10 further includes a reflective film 104 . The reflective film 104 is disposed on a side of the light guide plate 102 away from the light emitting surface.
[0046] In the above implementation process, the reflective film 104 can reflect the light onto the light guide plate 102, diffuse it to the light exiting surface of the light guide plate 102, and emit it from the light exiting surface of the light guide plate 102, thereby ensuring that the light is more uniform and reducing the phenomenon of uneven light caused by the light from the side of the light guide plate 102 away from the light exiting surface failing to pass through the light guide plate 102 again.
[0047] In some embodiments, the liquid crystal module 10 further includes a FOG 105 (liquid crystal glass), and the FOG 105 is in contact with a side of the optical film 103 facing away from the first boss.
[0048] In some embodiments, the frame 1011 is further configured with a second boss. The second boss is closer to the outer edge of the frame 1011 than the first boss. The side of the second boss facing away from the light guide plate 102 is used to contact the FOG 105 .
[0049] In some embodiments, the liquid crystal module 10 further includes an iron frame configured to fix the plastic frame 101 and the light guide plate 102. Exemplarily, the iron frame includes an upper iron frame 106 and a lower iron frame 107. The upper iron frame 106 is connected to the lower iron frame 107. The upper iron frame 106 is disposed at the outer edge of the lower iron frame 107. The reflective film 104 is disposed above the lower iron frame 107.
[0050] In a second aspect, the present application further provides a display device comprising the liquid crystal module 10 described above. The display device may be any product or component with a display function, such as a laptop display, electronic paper, an organic light-emitting diode display, a liquid crystal display, an LCD TV, a digital photo frame, a mobile phone, or a tablet computer.
[0051] Since the display device provided in the second aspect includes the liquid crystal module 10 , the display device has all the technical effects of the liquid crystal module 10 , which will not be described in detail here.
[0052] In all embodiments of the present application, "big" and "small" are relative, "more" and "less" are relative, and "up" and "down" are relative. The expressions of such relative terms will not be elaborated in the embodiments of the present application.
[0053] It should be understood that the phrases “in this embodiment,” “in an embodiment of the present application,” or “as an optional implementation” mentioned throughout the specification mean that specific features, structures, or characteristics related to the embodiment are included in at least one embodiment of the present application.

The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
