Description

Technical Field

[0001] This utility model relates to the field of liquid crystal module technology, specifically to a liquid crystal module with a double-sided screen display structure and its display device. Background Technology

[0002] With the rapid development of display technology, consumers' demands for display products are no longer limited to display effects, but also include higher requirements for appearance design, cost control, and ease of maintenance. Traditional display modules typically consist of components such as a backplate, fixing structures, LEDs, reflectors, light guide plates, optical films, a mid-frame, LCD glass, and a front frame. While this structure is mature, it suffers from the following problems: Significant thickness: The stacked multi-layer structure makes it difficult to further reduce the overall thickness of the module, failing to meet ultra-thin requirements. High cost: The large number of components leads to complex material costs and assembly processes, resulting in low production efficiency. Difficult maintenance: The tightly coupled components require disassembling the entire module to repair or replace a single component. Inability to achieve double-sided display: Traditional structures only support single-sided display, making it difficult to meet the needs of special application scenarios.

[0003] To address these issues, existing technologies have attempted to use plastic light guide plates or simplify structural designs. However, plastic light guide plates are prone to deformation and have poor optical performance, while simplified designs often sacrifice display quality or structural strength. Furthermore, double-sided display modules typically employ two independent backlight systems, resulting in doubled costs and increased thickness.

[0004] Therefore, there is an urgent need for a new type of LCD module structure that can achieve ultra-thin, low-cost, easy-to-maintain, and double-sided display functions while ensuring display quality. Utility Model Content

[0005] The present invention aims to overcome at least one of the defects of the prior art and provide a liquid crystal module and its display device with a double-sided screen display structure. By optimizing the structural design, it solves the problems of traditional modules being thick, costly, difficult to maintain, and unable to display on both sides.

[0006] Specifically, this utility model provides a liquid crystal module with a dual-screen display structure, including a top side and a bottom side. The middle part of the liquid crystal module is a light guide plate, and films and liquid crystal panels are arranged sequentially from the light guide plate to both sides. The top side is also provided with an extruded frame, which includes a edging portion, a first embedding portion and a second embedding portion. The edging portion is attached to the top side. The first embedding portion and the second embedding portion are symmetrical about the light guide plate as the central axis. The first embedding portion and the second embedding portion are respectively embedded between the films and liquid crystal panels on both sides.

[0007] Furthermore, the top end is also provided with a Π-shaped edge-sealing adhesive, the top of which is attached to the edge-sealing portion of the extruded frame; one end of the Π-shaped edge-sealing adhesive is embedded between the first embedded portion and the film on one side; the other end of the Π-shaped edge-sealing adhesive is embedded between the second embedded portion and the film on the other side.

[0008] Preferably, the first embedding part and the second embedding part are further provided with a first double-sided foam adhesive at the bonding points with the liquid crystal panel.

[0009] Furthermore, the ground side is also provided with a light strip and a heat sink; one end of the light strip is attached to the patch portion.

[0010] Furthermore, the heat sink includes an enclosure portion and a patch portion; the enclosure portion encloses the light strip, and the patch portion is attached to both sides of the light guide plate.

[0011] Furthermore, the enclosure portion and the patch portion are integrally formed, and the enclosure portion has a fin structure.

[0012] Furthermore, a second double-sided foam adhesive is provided between the liquid crystal panel and the diaphragm at the ground side end.

[0013] Furthermore, the liquid crystal module also includes a front frame, which is respectively attached to the outer side of the liquid crystal panels on both sides.

[0014] Preferably, the light strip is a side-mounted LED light strip.

[0015] This utility model also protects a display device, including the above-mentioned liquid crystal module.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention designs a glass light guide plate that covers the film on both sides, which is then inserted into an extruded frame. A light strip and heat sink are inserted into the ground side. The LCD panel is then attached to both sides of the extruded frame, and the front frame is covered to form a standard module structure. This design saves materials and processes, and achieves a universal backlight product form, applicable to the design of all edge-lit backlight modules in display products. The product has low overall cost, high production efficiency, exquisite appearance, and ultra-thin thickness; it enables modularization and standardization of backlight modules, reducing development and manufacturing costs.
