General Technical Guidelines for LED Screens

Conventional technical guidelines for LED screens. Many users lack experience in the basic knowledge of LED screens. We have summarized some basic knowledge of LED screens that users often consult to share with you, so as to ensure that customers can choose LED screen products rationally and will not enter the technical blind zone. Even if you only pay attention to the price of LED screens and choose low-quality LED products, knowing the parameters of LED screens is the first prerequisite. 1. Brightness: Due to the difference in illuminance indoors and outdoors, the requirements for the brightness of LED screens are also different. Under normal circumstances, the brightness of the indoor LED screen of United Huiye Technology is designed to be above 1200-1500cd/m2, and the brightness of the outdoor LED screen is set above 5000-7500cd/m2, which can not only ensure that the full-color LED screen has vivid colors and clear images when it is used normally, but also It can ensure that the LED screen has sufficient brightness and vivid and clear video images when the lamp tube attenuation exceeds 30%. 2. Clarity: Determine the specifications and area required for the LED screen according to the best viewing distance. For example, if the best viewing distance is 5-50 meters, then it is recommended to use a P5 LED screen (resolution "40000 pixels/m2), with an area of ​​10 About one square meter is enough. The most advanced 16-bit data interface is used to further improve the clarity of the picture. 3. Power supply and signal transmission mode: Because of the importance of full-color LED screens, the power supply and signal transmission must be technically special Processing, using high-quality military-grade connector design, and further controlling the faults caused by various pulling forces at the connector. 4. Refresh rate: Super Category 5 twisted-pair shielded wire is used between the processor and the LED screen, and high performance is configured The control IC can design the high refresh rate of the LED screen above ≧960HZ to ensure that there is no water ripple and flicker when the video is played, the full digital loss is low, and it is resistant to electromagnetic interference. 5. Raw materials: All raw materials of the LED screen of United Huiye Technology All use the high-quality supplier products that can stand the test of time to ensure the display effect and stability. 6. Control method: use the self-designed control system, and conduct 240-hour uninterrupted power-on aging screening, and then select highly reliable Control system. In addition, dual redundant hot backup is adopted in the control mode. Once a problem occurs, it will be connected to another signal line immediately to continue to work normally and connect smoothly. 7. Product quality control: All products are strictly in accordance with the ISO9001-2000 quality certification system Documents for product manufacturing. Outdoor LED screens will be tested in strict accordance with the waterproof level IP65 to achieve a complete waterproof effect. LED screen installation and debugging, LED screen installation and debugging are strictly in accordance with the design plan, and the installation level reaches C level or above (the highest level of LED screen installation). 8. Three-level product aging process: firstly, conduct 24-hour power-on aging on the modules produced by the automated assembly line, then conduct 48-hour power-on aging on a single box, and finally simulate on-site assembly of finished screens for 72 hours of continuous power-on aging. Assembled on site. .
