How to choose an outdoor waterproof screen?

When choosing an outdoor waterproof screen, the following aspects can be considered:

1. Protection level: Outdoor display screens generally require a waterproof level of IP65 or above. The IP65 rating indicates that the product "completely prevents dust from entering and causes no harm when rinsed with water". If used in harsh environments, such as areas frequently exposed to heavy rain or close to water sources, displays with IP66, IP67 or even IP68 ratings can be chosen, as they offer higher waterproof performance.

2. Display effect brightness: The outdoor environment has complex light. To ensure that the screen content is clearly visible in strong light, the screen brightness is best to reach 1000 nits or more.

Contrast and color reproduction: High contrast can make the details of light and dark in the picture more prominent, while high color reproduction can ensure the authenticity and vividness of the image colors, making the advertisement or information display more attractive.

Resolution: Select an appropriate resolution based on the usage scenario and viewing distance. Generally speaking, for places with a long viewing distance, such as squares and beside highways, a screen with a lower resolution but higher brightness can be chosen. When viewing the display screens at close distances, such as bus stops and subway stations, high-resolution screens should be chosen to present clearer images and text.

3. Material and Process: The shell material should be waterproof, dustproof, corrosion-resistant and have good weather resistance, such as stainless steel, aluminum alloy or special engineering plastics, etc., to resist the erosion of rain, wind and sand, ultraviolet rays, etc.

Sealing process: Reliable sealing techniques should be adopted for the frame, seams, interfaces and other parts of the display screen, such as using waterproof sealant and waterproof sealing strips, to prevent water from seeping into the interior and damaging electronic components.

Circuit board protection: Circuit boards can be selected with waterproof coatings or equipped with waterproof covers to enhance their reliability in humid environments.

4. Heat dissipation performance: When outdoor waterproof screens are in operation, they generate heat. Coupled with factors such as sunlight exposure, the heat dissipation issue cannot be ignored. A good heat dissipation design can ensure that the screen operates within an appropriate temperature range and extend its service life. You can choose products with cooling methods such as cooling fans, cooling fins, air conditioning cooling or forced air cooling cooling.

5. Anti-reflection performance: The outdoor environment has variable light. If the screen reflects light severely, it will affect the viewing effect. Special coated glass or screens with anti-reflective coatings should be selected to reduce reflection and improve the viewing Angle and resolution of the picture.

6. Lightning protection and electromagnetic interference protection: Outdoor display screens need to have reliable lightning protection designs to ensure safety during thunderstorms. At the same time, shielding measures should be adopted for internal electrical components to prevent interference from internal devices and cables to signals, as well as interference from external electromagnetic fields to display products.

7. Installation and Maintenance: Select products that are easy to install and maintain. The outdoor environment is complex, and the probability of equipment failure is relatively high. Screens that are easy to disassemble and replace components can reduce maintenance costs and difficulty.

8. Brand and After-sales Service: Choose well-known brands and manufacturers with good reputations, as their products are more reliable in terms of quality, performance and stability. At the same time, a complete after-sales service is also very important, including the warranty period, maintenance response time, technical support, etc., so that problems encountered during use can be solved in a timely manner.
