[0018] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.
[0019] Please refer to Figure 1 and Figure 2As shown, a spliced LED liquid crystal display includes a mounting base plate 1, an LED lamp plate 2, a functional plate 3, a liquid crystal display plate 4 and a glass plate 5. The mounting base plate 1 is provided with a clamping ring 11 and a clamping groove 12. The clamping ring 11 and the clamping groove 12 are arranged on the inner side of the mounting base plate 1. The clamping ring 11 is arranged close to the bottom of the mounting base plate 1. The clamping groove 12 is arranged close to the opening of the mounting base plate 1. The LED lamp plate 2 is mounted on the bottom of the mounting base plate 1 and abuts against the clamping ring 11. The functional plate 3 is fixed around the clamping ring 11. The liquid crystal display plate 4 and the glass plate 5 are clamped in the clamping groove 12. The liquid crystal display plate 4 is arranged close to the glass plate 5. The LED lamp plate 2 is provided with LED lamps 21. The LED lamps 21 are arranged equidistantly on the LED lamp plate 2. The LED lamps 21 emit light and the light is emitted through the functional plate 3. The light is utilized and diffused uniformly. The structure design can greatly improve the light utilization rate and uniformity of the LED lamps, thereby improving the brightness uniformity of the backlight module. The functional plate 3 includes a fluorescent layer 31, a light guide plate 32 and a diffusion film 33. The fluorescent layer 31, the light guide plate 32 and the diffusion film 33 are arranged close to each other from bottom to top. The fluorescent layer 31 contains first diffusion particles. The first diffusion particles are PMMA particles. The fluorescent layer 31 can change the LED from a point light source to a surface light source, thereby shortening the light mixing distance, making the backlight module thin, and improving the uniformity of the light and reducing light loss by the structure design of the diffusion film. The mounting base plate 1 is spliced with the adjacent mounting base plate 1, thereby splicing multiple LED liquid crystal displays to form LED liquid crystal displays of various sizes. The production efficiency is improved. The small-size LED liquid crystal display is convenient to process and the production equipment occupies a small area.
