Outdoor LED large screen is irreplaceable for businesses

Now many merchants use LED large screens as a tool for publicity to the audience. There is no doubt that LED screens have the value of priority. First of all, the LED large screen has an unlimited capacity to play advertisements, and can insert or change video content anytime and anywhere, and can attract the audience's attention by changing the color of the flicker, and can improve the grade of the store. So what issues need to be paid attention to when purchasing large LED screens? As an industry insider, United Huiye Technology will share with you the precautions for outdoor LED large screens. Brightness, pixels, and protection are very important when buying outdoor LED large screens. Compared with indoor LED large screens, outdoor LED electronic screens require higher resolution to meet the long-distance and high-light environment. The traditional liquid crystal display can only reach 1024×768, and the outdoor LED large screen resolution needs to reach at least 1920×1200 to display normally under the influence of sunlight without affecting the viewing effect; if you want to make the outdoor LED large screen adapt to complex In the changing outdoor environment, in addition to the resolution of the display screen, the waterproof, dustproof, anti-theft, lightning protection, anti-riot, anti-reflection, anti-electromagnetic interference, etc. of the outdoor LED large screen need to be solved. What are the special requirements for outdoor LED large screens in addition to the conventional configuration? The location of the equipment is different. Outdoor LED large screens must have equipment that understands the temperature to ensure the normal use of the screen. Regardless of the cooling scheme of air-conditioning or forced air cooling, outdoor LED large screens generally meet the temperature: -30℃—— 55°C, humidity: 10% - 90% operating requirements. The outdoor LED large screen must be waterproof and dustproof. If you want to use it in all outdoor climates, waterproof and dustproof is the first thing to face. The protection level of the display device casing must be waterproof. Generally, the waterproof level reaches IPX5 and can operate normally in heavy rain; Dust is an important factor that accelerates the aging of outdoor LED screens. Outdoor display equipment must have a specially designed dust-proof structure and dust-proof filter equipment, that is, the protection level must reach IP65. Outdoor LED large screens need to be anti-reflective. To make the interface clearly visible in outdoor environments, it is necessary to use specially coated glass to improve the visual angle and resolution of the screen and reduce screen reflections. Outdoor LED large screens need lightning protection. In order to achieve all-weather outdoor playback performance, outdoor display equipment must also have reliable lightning protection and electronic control design to provide safety guarantee for the equipment in thunderstorm days. Outdoor LED large screens should be anti-riot and anti-theft. Outdoor LED large screens are generally used in outdoor public places, so the safety of the LED large screen itself should be considered first. Screws should be avoided from being exposed, and combined with anti-theft locks and strong structures Support to solve the problem of anti-theft. Anti-electromagnetic interference, the uncontrollable outdoor environment makes the anti-electromagnetic interference of outdoor LED large screens very important. We cannot change the environment used outdoors, but we can use shielding methods for the internal electronic components of LED large screens, that is, effectively prevent internal devices from , The interference of the cable on the signal can also prevent the interference of external electromagnetics on the LED screen products. .
