Description

Technical Field

[0001] This utility model relates to the field of liquid crystal module technology, specifically to a liquid crystal module with an extruded frame and a glass light guide plate. Background Technology

[0002] In the field of display technology, edge-lit backlight modules are widely used in products such as televisions and monitors due to their ultra-thin design and efficient optical performance. Traditional edge-lit backlight modules typically consist of components such as a backplate (back cover), fixing structures, LEDs, reflectors, light guide plates, diaphragms, a mid-frame, liquid crystal glass, and a front bezel (face bezel). While this structure can meet basic display requirements, it presents the following problems in practical applications:

[0003] Complex structure and high cost: Traditional backlight modules require multiple components to be stacked and assembled, resulting in a complex structure and numerous production processes, which not only increases manufacturing costs but also reduces production efficiency.

[0004] Insufficient strength: In traditional designs, the back panel serves as the main structure, which is relatively soft and easily deformed, affecting the product's stability and durability.

[0005] Maintenance difficulties: Due to the tight stacking of components, multiple components need to be disassembled during maintenance, increasing the difficulty and cost of maintenance. Aesthetic limitations: Traditional structures struggle to meet the design requirements of ultra-thin and full-screen displays, limiting product innovation in appearance. To address these issues, existing technologies have attempted different material and structural optimization solutions. For example, current technologies use plastic light guide plates or metal frames, but these still have shortcomings in terms of strength, cost, or optical performance. Furthermore, existing backlight modules are mostly non-standardized designs, making modularization and universalization difficult, further limiting their application scope and economic benefits.

[0006] Therefore, there is an urgent need for a new type of backlight module structure that can simplify the assembly process, reduce costs, increase strength, and meet the design requirements of ultra-thin and full-screen displays while ensuring display quality. Utility Model Content

[0007] The present invention aims to overcome at least one of the defects of the prior art and provide a liquid crystal module with an extruded frame and a glass light guide plate, so as to achieve the purpose of low overall cost and high production efficiency.

[0008] This utility model provides a liquid crystal module with an extruded frame and a glass light guide plate, including a top end and a bottom end. From the front to the back, it includes a liquid crystal panel, a film, a glass light guide plate, reflective paper, a metal backplate heat sink, and a cover plate. The bottom end is also provided with a light strip. The light strip is disposed in the heat dissipation space formed by the metal backplate heat sink. The top end is also provided with an extruded frame. The extruded frame includes an edge-sealing part, a first engaging part, and a second engaging part. The edge-sealing part is attached to the top end and both sides of the liquid crystal module. The first engaging part is embedded between the liquid crystal panel and the film. The second engaging part is disposed between the metal backplate heat sink and the cover plate.

[0009] This utility model discloses a liquid crystal module with an extruded frame and a glass light guide plate as a backlight for a TV or monitor. The glass material is used as the main structure of the light guide plate, and the iron back plate and film are wrapped together with the extruded frame. Then, the iron cover plate is attached to the extruded frame. The product has low overall cost, high production efficiency, full-screen appearance, and ultra-thin thickness. It can use the modularization and standardization of backlight modules to reduce development and manufacturing costs.

[0010] Preferably, the second engaging portion includes a first support portion, a second support portion, and a third support portion; the first support portion is perpendicular to the edge portion and one side is attached to the iron back plate radiator; the second support portion is perpendicular to the first support portion, the third support portion extends from the second support portion toward the edge portion and hooks back toward the first support portion at its end, and one side of the third support portion is attached to the cover plate.

[0011] This invention achieves a standard screw hole and latch structure for a single backlight source in traditional edge-lit backlight display products, which can be secured using an extruded frame. Currently, existing backlight modules use a single backplate as the main structure, and the backlight material can only be assembled by stacking layers inside the machine, resulting in relatively weak overall strength. This invention uses an extruded frame and a glass light guide plate as the main structure, which wrap around an iron backplate heat sink and a film, and then engages in the slots formed by the first and second engaging parts of the extruded frame. The iron backplate heat sink is then attached to the cover plate and then to the LCD panel, resulting in an ultra-thin, low-cost, aesthetically pleasing, and easily automated TV and monitor display product.

[0012] Furthermore, double-sided foam adhesive is provided between the first support portion and the liquid crystal panel.

[0013] Furthermore, the liquid crystal module also includes an edge-sealing adhesive, which includes a first bonding part and a second bonding part, which together form an L-shape; wherein one side of the first bonding part is bonded to the edge-sealing part, and the other side is bonded to the top end of the film and glass light guide plate; one side of the second bonding part is bonded to the iron back plate heat sink, and the other side is bonded to the first support part.

[0014] Furthermore, a first foam adhesive is provided between the third support and the cover plate.

[0015] Furthermore, the ground side is also provided with a lower frame, which is U-shaped, with the liquid crystal panel fixed to the inner side of one end and the other end embedded in the front of the cover plate.

[0016] Furthermore, the liquid crystal module also includes a PC sheet disposed on the back of the cover plate. Therefore, this invention uses an extruded frame and a glass light guide plate as the main structure. After wrapping the iron backplate heat sink and the film, they are engaged in the slots of the extruded frame. The iron cover plate and the PC sheet are then attached to the back, and finally the liquid crystal panel is attached. The PC sheet serves both aesthetic and further fixing purposes. Preferably, a second foam adhesive is also provided between the cover plate and the PC sheet.

[0017] Furthermore, the LCD module also includes a bracket, which comprises an integrally formed support plate and a U-shaped frame; the support plate is embedded in the back of the iron backplate heat sink; one end of the U-shaped frame is connected to the support plate, and the other end supports the LCD panel. The bracket is made of iron, and the protruding structure of the U-shaped frame can fix the edge of the iron backplate heat sink, ensuring the flatness of the iron backplate.

[0018] Furthermore, the ground side end is also provided with fastening screws, which connect the lower frame, the iron backplate heat sink, and the U-shaped frame sequentially from the outside to the inside. The lower frame, the iron backplate heat sink, and the U-shaped frame are provided with screw holes. Using the hook structure of the lower frame, the iron backplate heat sink, and the U-shaped frame, they can be engaged by extruding the frame, enabling quick assembly and disassembly. Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model protects a liquid crystal module device with an extruded frame and a glass light guide plate. The main structure uses an extruded frame to bond the liquid crystal panel, and fixes the glass light guide plate and the iron back plate heat sink. The outer structure uses a PC sheet. The slots of the extruded frame are used to hold the iron back plate heat sink, the glass light guide plate and the film. Then the liquid crystal panel is bonded to the extruded frame. This changes the existing backlighting method. The design of screws and clips saves materials and processes, and achieves a product form with a universal backlight. It can be applied to the display product design of all edge-lit backlight modules. Attached Figure Description
