Description

Technical Field

[0001] The utility model relates to the field of liquid crystal display screens, in particular to a liquid crystal display screen module structure. Background Art

[0002] Liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. LCD displays use two polarized materials, with a liquid crystal solution between them. When an electric current passes through the liquid, the crystals are rearranged so that light cannot pass through them. Therefore, each crystal is like a shutter, which can allow light to pass through and block light. Liquid crystal display (LCD) is currently developing towards the goal of being light, thin, short and small. Display products with a long history in computer peripherals are of course no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube displays and LED display panels are all subject to factors such as large size or huge power consumption, and cannot meet the actual needs of users. The development of liquid crystal display technology is just in line with the current trend of information products. Whether it is right-angle display, low power consumption, small size, or zero radiation, it can allow users to enjoy the best visual environment. A Chinese patent discloses a liquid crystal display module structure (authorization announcement number CN 209657039 U), this patented technology can prevent the optical film from generating ripples under the condition of thermal expansion and contraction by setting an elastic rubber layer with air bags in the positioning groove of the light guide plate, thereby maintaining clear image quality for a long time; it can prevent the edges and corners of the optical film from being worn during processing and transportation, and play a role of buffer protection. However, the side panels of this design are arranged at the periphery of the bottom plate and form a storage space for accommodating the light guide plate. A positioning groove is arranged in the middle of the side of the light guide plate away from the bottom plate, and a buffer edge is formed by the protrusions on both sides of the bottom layer and a flange is formed from the top of the buffer edge to the inside. The bottom layer of the elastic rubber layer is arranged on the bottom wall of the positioning groove, and the buffer edge of the elastic rubber layer is provided with air bags and fixedly connected to the side wall of the positioning groove. The reflective plate is arranged on the bottom layer of the elastic rubber layer, and the optical film is arranged on the reflective plate. This structure has little protection for the liquid crystal display screen, is not convenient for protecting the liquid crystal display screen, and is not convenient for replacement and maintenance. Therefore, those skilled in the art provide a liquid crystal display screen module structure to solve the problems raised in the above background technology. Utility Model Content
