[0002] The semi-internal and semi-external light source sunlight screen is a special screen technology that combines the characteristics of internal and external light sources, and is designed to provide excellent display effects under various lighting conditions. The semi-internal and semi-external light source sunlight screen is usually energy-saving and environmentally friendly. It can intelligently adjust the use of internal and external light sources when needed to minimize power consumption. It adopts special optical box structure, single-layer polarizer, high-reflective silver reflective coating, and scattering film. These structures work together to enable the sunlight screen to effectively reflect and utilize ambient light in direct sunlight or other strong light environments, improve display brightness and contrast, reduce glare and reflections, and thus enhance the visual experience when used outdoors.

[0003] The semi-internal and semi-external light source sunlight screen often includes a backlight module, which is used to provide sufficient brightness when the ambient light is insufficient. The backlight panel is composed of LEDs or other light-emitting elements, which are used to provide sufficient brightness when the ambient light is insufficient. The purpose of adjusting the internal light source is achieved by evenly distributing the light on the entire screen. However, there are more light-emitting elements on the backlight panel, which will generate more heat when working. Currently, most of the heat is dissipated through cooling fans, but this can easily cause external dust to enter the screen casing. The dust will accumulate on the surface of the backlight panel, which not only affects the life of the backlight panel, but also affects the light output. Therefore, a semi-internal and semi-external light source sunlight screen is needed to solve the above problems. Utility Model Content
