[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides the following technical solution: a light-transmitting grating LED full-color display screen, in which a light guide plate, a light enhancement film, a diffuser, a polarizer, and a display panel are installed sequentially from bottom to top in a plastic frame during use. A prism film is provided on the side of the diffuser near the polarizer, and an anti-reflection and anti-reflection film is provided on the inner wall of the display panel. By installing the anti-reflection and anti-reflection film on the inner wall of the display panel, the light transmittance of the display module can be increased, and the influence of ambient light on the display module can be reduced, thereby improving the user experience.

[0025] Figures 1-3 The diagram shown is a structural schematic of the first embodiment of the light-transmitting grating LED full-color display screen of this utility model. Please refer to [link / reference]. Figures 1-3 The main body of the light-transmitting grating LED full-color display screen of this embodiment includes a plastic frame 100.

[0026] A backlight panel 110 is installed inside the plastic frame 100. Several LED light sources 120 are installed on one side of the backlight panel 110. From bottom to top, the backlight panel 110 is provided with a light guide plate 130, a brightness enhancement film 140, a diffuser 150, a polarizer 160, and a display panel 170. The light guide plate 130, the brightness enhancement film 140, the diffuser 150, the polarizer 160, and the display panel 170 are installed inside the plastic frame 100 from bottom to top. A prism film 151 is provided on the side of the diffuser 150 near the polarizer 160. An anti-reflection and anti-reflection film 171 and a grating layer 172 are respectively provided on both sides of the display panel 170.

[0027] The LED light source 120 includes several LED beads, a PCB circuit board and a driver chip, and the LED beads are evenly distributed on the PCB circuit board. The display panel 170 is made of glass material and the surface is treated with anti-reflection to reduce ambient light interference. The light guide plate 130 is made of acrylic material.

[0028] The plastic frame 100 supports the backlight panel 110, light guide plate 130, brightness enhancement film 140, diffuser 150, polarizer 160, and display panel 170. The backlight panel 110 provides backlight to the display module through an LED light source 120. The LED light source 120 is specifically composed of several LED beads, a PCB circuit board, and a driver chip. The LED beads are typically composed of red, green, and blue LEDs. By adjusting their brightness and combination, a full-color display effect is achieved. The driver chip controls the brightness and color of the LED beads to achieve precise display control. The PCB circuit board is used to connect and fix the LED beads and the driver chip, providing electrical connections and signal transmission. The light guide plate 130 guides the light generated by the LED light source 120 to the brightness enhancement film 140. The brightness enhancement film 140, through its microprism structure, refocuses scattered light onto the front, thereby increasing the axial brightness of the screen. The diffuser 150 diffuses light, converting point or line light sources into surface light sources, thereby reducing brightness unevenness on the screen and improving the overall brightness uniformity. The polarizer 160 converts natural light into polarized light in a specific direction, allowing only light rays aligned with the transmission axis of the polarizer 160 to pass through, while light rays in other directions are blocked. The prism film 151 enhances the screen's contrast by increasing brightness within a specific viewing angle range, making images clearer and more vivid. It can concentrate light within a specific viewing angle range, reducing the scattering of side light, thereby improving the screen's viewing angle effect.

[0029] The light guide plate 130, light enhancement film 140, diffuser 150, polarizer 160, and display panel 170 are installed sequentially from bottom to top within the plastic frame 100. A prism film 151 is provided on the side of the diffuser 150 near the polarizer 160, and an anti-reflection and anti-reflection film 171 is provided on the inner wall of the display panel 170. By installing the anti-reflection and anti-reflection film 171 on the inner wall of the display panel 170, the light transmittance of the display module can be increased, and the influence of ambient light on the display module can be reduced, thereby improving the user experience.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
