Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal modules, in particular to a double-layer iron backboard liquid crystal module. Background Art

[0002] All display products such as monitors and televisions are constantly improving their pursuit of product shape while pursuing display effects and performance. Exquisite appearance and low cost have become one of the topics of continuous exploration and research. The backlight module structure in the prior art generally assembles and fixes the back panel, fixed structural parts, reflective sheets, light guide plates, optical composite films and other structures layer by layer through screws. The assembly is more cumbersome and the process is complicated. In addition, the backlight module is a set of back panels as the main structure. The backlight material can only be assembled from the inside of the machine, and the overall strength is relatively weak. Utility Model Content

[0003] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a double-layer iron back plate liquid crystal module to achieve the purpose of simple and compact structure and low cost.

[0004] The utility model provides a double-layer iron backplane liquid crystal module, which comprises, from inside to outside, a first iron backplane, a backlight body, and a liquid crystal panel; the double-layer iron backplane liquid crystal module also comprises an S-shaped card slot; the backlight body comprises, from inside to outside, a second iron backplane, a reflective sheet, a glass light guide plate, and a composite diaphragm; the S-shaped card slot is arranged at the ground side end of the double-layer iron backplane liquid crystal module; one end of the S-shaped card slot is embedded between the liquid crystal panel and the composite diaphragm, and the other end is embedded between the first iron backplane and the second iron backplane, so that the second iron backplane, the reflective sheet, the glass light guide plate, and the composite diaphragm form an integral backlight body.

[0005] The utility model uses a second iron back plate, a reflective sheet, a glass light guide plate, and a composite film to be stacked, and then uses an S-shaped card slot to extrude a frame to form an integral component as a backlight main structure, and then the backlight main structure is clamped into the first rear iron back plate, which is simple and convenient to install. The entire structure does not require screw assembly, and the installation is quick and convenient. Unlike the prior art in which the backlight main body is relatively soft, the utility model is designed to use a rear iron back plate, that is, the first iron back plate and the second iron back plate as the back plate structure, and uses an S-shaped frame to fix the integrated wrapped glass light guide plate assembly on the back plate, and then affixes double-sided tape to fix the liquid crystal glass, to achieve a display product with a light-transmitting appearance, ultra-thin, low-cost, and exquisite appearance of TV and monitors.

[0006] Furthermore, a double-sided foam adhesive is provided between the S-shaped card slot and the liquid crystal panel. The double-sided foam adhesive can fix one end surface of the S-shaped card slot to fix the S-shaped card slot and the liquid crystal panel, and has the function of buffering and protecting the liquid crystal panel.

[0007] Furthermore, it also includes a back plate buckle disposed at the other end of the S-shaped slot and clamped between the S-shaped slot and the first iron back plate. Since there is a certain space between the other end of the S-shaped slot and the first iron back plate, the back plate buckle can fill the other end of the S-shaped slot and fix it with the first iron back plate.

[0008] Furthermore, light-transmitting holes are provided on the first iron back plate and the second iron back plate; a light-transmitting film is also provided on the outer side of the second iron back plate, and a LOGO or pattern is provided on the light-transmitting film; when the first iron back plate is lit, a part of the light passes through the reflective sheet, passes through the light-transmitting holes, and shines on the LOGO or pattern of the light-transmitting film, thereby achieving the effect of lighting up the LOGO or pattern.

[0009] The utility model digs holes on the second iron back plate to make it light-transmissive, and at the same time, the first iron back plate is also dug with holes, and then a light-transmissive appearance film of a corresponding shape is placed: containing a LOGO or a pattern. When the second iron back plate is lit, a portion of light passes through the reflector, passes through the second iron back plate with holes, and irradiates the LOGO or pattern of the appearance film of the first iron back plate, thereby achieving the effect of lighting up the appearance LOGO or pattern, thereby changing the existing backlight module structure, and no screw design is required, which not only saves materials and processes, but also realizes a product form that can be universal for the backlight source, and can be applied to the display product design of all side-lit backlight modules.

[0010] Furthermore, the second iron back plate forms a heat dissipation space at the sky side end; the double-layer iron back plate liquid crystal module also includes a light bar, and the light bar is arranged in the heat dissipation space.

[0011] Therefore, the utility model adopts the iron back plate to enhance the structural hardness and also play a role in heat dissipation.

[0012] Furthermore, the light bar is T-shaped; the end of the second iron back plate is embedded between the liquid crystal panel and the glass light guide plate; and is on the same plane as the composite film.

[0013] The heat dissipation space is a semi-enclosed structure. One end of the second iron back plate is bent and enclosed to form the heat dissipation space, which serves as a support for the backlight body and also plays a role in heat dissipation, thereby reducing the design of components.

[0014] Furthermore, the double-layer iron back plate liquid crystal module of the utility model further comprises a front frame for fixing the day side end of the double-layer iron back plate liquid crystal module, and the front frame is in a 7-shape.

[0015] Furthermore, the first iron back plate is in a 7-shape, and one end is used to fix the side end of the double-layer iron back plate liquid crystal module.

[0016] The front frame and the first back plate together surround the back and sides of the liquid crystal module to achieve fixation.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model uses a liquid crystal module with a double-layer iron back plate structure with a light-transmitting LOGO effect as a light guide component of the backlight source, which can improve production efficiency and reduce costs. At the same time, it has a beautiful appearance and ultra-thin thickness, thereby reducing development and manufacturing costs.

[0019] The utility model uses a double-layer iron plate as the back plate structure, which has higher hardness and stability. At the same time, an S-shaped card slot is used on the back plate to fix the integrated wrapped glass light guide plate assembly, and then a double-sided adhesive is attached to fix the liquid crystal glass to achieve a light-transmitting appearance effect, and the overall ultra-thin, low-cost, and exquisite appearance of the TV and monitor display products.
