The thickness requirements for outdoor high brightness screens are closely related to their functional design, environmental adaptability, and heat dissipation performance. The following are the key points after comprehensive analysis of search results:
1. Balance between thickness and heat dissipation performance
Outdoor high brightness screens require high brightness (usually above 500 nits, with some scenes requiring 2000-5000 nits), and the internal backlight source has a large number of LEDs, resulting in a significant increase in heat generation. To ensure heat dissipation efficiency, sufficient space should be reserved for designing heat dissipation channels, such as air-cooled systems or air conditioning modules. Ultra thin design may affect stability due to compressed heat dissipation space, and even cause local black screen and other malfunctions.
For example, Ruisheng's 32 inch high brightness screen has a thickness of 41mm and adopts an aluminum substrate backlight scheme to optimize heat dissipation, while some 75 inch screens, although only 29.6mm thick, require specific heat dissipation designs (such as direct type DLED backlight) to ensure stable operation in high temperature environments.
2. The correlation between protection level and structural design
Outdoor high brightness screens need to reach IP65 or higher protection level to resist environmental erosion such as rain and dust. This requires the shell design to have a multi-layer sealing structure, such as waterproof rubber strips, dust-proof filters, etc. The integration of these components will increase the overall thickness of the machine. Qualified outdoor equipment enclosures typically have a thickness exceeding 20cm (excluding small sizes) to ensure the inclusion of modules such as waterproofing, lightning protection, and typhoon resistance.
3. Differences between actual cases and manufacturer designs
Different manufacturers have different requirements for thickness based on product positioning and technical solutions. For example:
Fengshi Technology's 75 inch high brightness screen has a thickness of 29.6mm and a brightness of 3000 nits, using DLED backlight technology.
Ruisheng's 32 inch screen has a thickness of 41mm and a power consumption as low as 100W, emphasizing the balance between heat dissipation and brightness.
These differences indicate that thickness is not the only indicator, and should be considered in conjunction with brightness, heat dissipation scheme, and protection level.
4. Potential risks of ultra-thin design
Some manufacturers may pursue a lightweight appearance by reducing heat dissipation space or adopting low-cost backlight solutions, but such designs can easily lead to black screens (LCD panels temporarily fail due to high temperatures) or shortened lifespan under high temperatures.
summarize
The thickness of outdoor high brightness screens is not necessarily thinner, but needs to match the requirements of heat dissipation, protection, and functionality. The typical thickness range varies greatly due to size and design differences (such as 32 inches about 40mm, 75 inches about 30mm), and the core is to ensure the integrity of the internal heat dissipation space and protective structure. Users should prioritize products with mature technology and reliable heat dissipation solutions to avoid sacrificing performance due to excessive pursuit of thinness.
