Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of LCD, especially relates to a wrinkle-proof LCD module. BACKGROUND

[0002] In modern electronic devices, LCD (Liquid Crystal Display) modules are widely used in various display devices such as smartphones, tablets, laptops, monitors and televisions due to their high resolution, low power consumption and cost-effectiveness. However, LCD modules often face film layer wrinkling problems caused by external pressure, mechanical vibration or temperature changes during use. Such wrinkles not only affect the display effect and reduce user experience, but also may shorten the service life of the device and increase maintenance costs.

[0003] In traditional LCD module design, there is usually a lack of effective buffer layer between the pressing strip and the display screen, which makes the display screen prone to damage when subjected to external force. In addition, the flatness of the brightness enhancement film, which is a key component for improving backlight efficiency, is crucial to the display effect. However, in existing designs, the brightness enhancement film is also prone to wrinkling under the influence of thermal expansion and contraction, affecting the uniform distribution of light. SUMMARY

[0034] Reference Figures 1 to 6 This utility model provides a wrinkle-resistant LCD module, including: a frame 1, mounting bases 2 disposed at both ends within the frame 1, a pressure strip 3, a brightness enhancement film 5, and an LCD display screen 4; the pressure strip 3 is disposed on the top of the mounting base 2, the LCD display screen 4 is disposed on the pressure strip 3, and a gap 41 is reserved between the top of the LCD display screen 4 and the top of the frame 1, the gap 41 being filled with soft cotton (not shown in the figure) to cushion the LCD display screen 4 and prevent damage; the pressure strip 3 also has a groove 301, which is positioned directly below the LCD display screen and is filled with soft silicone; the brightness enhancement film 5 is disposed on the mounting base 2 and positioned below the LCD display screen 4, the top of the mounting base 2 having multiple spaced-apart clips 200; the head of the brightness enhancement film 5 is clipped onto the clips 200, and a gap 53 is reserved between the top of the brightness enhancement film 5 and the bottom of the pressure strip 3, the gap 53 being filled with soft silicone.

[0035] Beneficial effects of Soft Silicone 1: Enhanced cushioning performance: As a compressible elastic silicone, Soft Silicone 1 can deform under pressure, absorbing impact force and thus providing effective cushioning protection for the LCD display. This design significantly improves the module's resistance to external impacts and reduces display damage caused by compression.

[0036] The beneficial effects of soft silicone 2: Counteracting compressive stress: Soft silicone 2 counteracts the compressive stress on the brightness enhancement film through its elastic deformation, preventing wrinkles. This design ensures the stability and functionality of the brightness enhancement film, avoiding reduced light efficiency and image quality caused by wrinkles. Improving light efficiency: By preventing wrinkles in the brightness enhancement film, soft silicone 2 helps maintain the light refraction and reflection efficiency of the film, thereby improving the light efficiency of the entire backlight module and the brightness uniformity of the display.

[0037] Furthermore, the wrinkle-resistant LCD module also includes a light board, which is disposed at the bottom of the mounting base; the light board 6 serves as the light source and its function is to provide a stable light source.

[0038] The head of the brightness enhancement film 5 has multiple slots that are adapted to the clip 200, and the width of the slots is greater than the width of the clip, which facilitates the installation and engagement of the brightness enhancement film.

[0039] Furthermore, the top of the mounting base 2 is provided with a protrusion 201, and the two sides of the protrusion 201 are provided with step position one 202 and step position two 203, with multiple retaining strips 200 distributed at intervals on the protrusion 201. The pressure strip 3 has a T-shaped structure, with the bottom of its vertical part placed on step position two 203, the top abutting against the top of the frame 1, and the horizontal part placed on the protrusion 201; the pressure strip 3 can be firmly installed on the mounting base 2 through the cooperation of the step position and the protrusion, avoiding displacement or damage to the LCD display screen 4 due to the pressure strip loosening.

[0040] The LCD display screen 4 is placed on the horizontal part, and the corresponding brightness enhancement film 5 is placed on the step position 202. The frame 1 is made of aluminum alloy. Aluminum alloy has good thermal conductivity, which can effectively dissipate the heat inside the module, improve the heat dissipation efficiency of the LCD module, and extend its service life.

[0041] The technical solution of this utility model has the following beneficial effects:

[0042] By creating gaps one and two between the top of the LCD display and the frame, and below the pressure strip, and filling them with soft cotton and soft silicone, this invention significantly enhances the module's resistance to compression. This design effectively absorbs and disperses external pressure, reducing direct impact on the display and brightness enhancement film, thereby lowering the risk of wrinkles and other forms of damage.

[0043] By pre-drilling grooves on the pressure strip and filling them with soft silicone, the impact of external forces or temperature changes on the display screen is effectively buffered, ensuring the stability and reliability of the display effect.

[0044] Enhanced protection: A gap is provided between the top of the LCD and the top of the frame and filled with soft cotton to effectively prevent breakage when subjected to external impact, while protecting the internal LCD display from damage, thus improving the module's safety and durability.

[0045] Enhanced structural stability: The use of an aluminum alloy frame provides a solid support for the LCD module. Its lightweight, high strength, and excellent heat dissipation performance not only reduce the overall weight of the module but also improve heat dissipation efficiency and extend the module's service life.

[0046] Extended lifespan: Effective protection and buffering measures reduce the occurrence of faults such as film wrinkles and component damage, lower the frequency of maintenance and replacement, extend the lifespan of LCD modules, and improve the cost-effectiveness of products.

[0047] Enhancing Product Competitiveness: Stable display performance, reliable protection, and ingenious structural design make the LCD module of this application more competitive in the mobile device and display market, meeting consumers' demand for high-quality display products and helping to increase the product's market share and brand reputation.
