With the increasing demand for outdoor advertising in the market, the scale of application of outdoor LED displays has expanded rapidly. In the face of the complicated products on the market, how can industry users buy products that satisfy themselves? Understanding the parameters of the LED display is a prerequisite.
1. Clarity: According to the best viewing distance point, determine the required area of ​​the screen, the definition of "40000 pixels / m2" optimal distance is 5-50 meters; use the most advanced 16-bit data interface to further improve the clarity of the picture degree.
2. Brightness: The brightness of the screen is designed to be above 2500cd/m2, which not only ensures the vivid color and clear image when the indoor full-color LED display is in normal use, but also ensures that the LED display has a lamp attenuation of more than 30%. Enough brightness and vividness of the video image. Refresh rate: Super 5 types of twisted-pair shielded wires are used between the processor and the screen. High-performance control ICs can be configured to design the high refresh rate of the screen at ≧1000HZ to ensure that there is no water ripple and flicker during video playback. Low total digital loss and immunity to electromagnetic interference. Power supply and signal transmission: Because of the importance of the full-color LED display, the power supply and signal transmission must be technically treated with high-quality military-grade connectors. Further faults caused by various pull-up forces are controlled at the connector.
3. Control mode: Select the self-designed control system and conduct 240-hour uninterrupted power-on aging screening to select a highly reliable control system. Moreover, the dual redundant hot backup is adopted in the control mode, and once the problem occurs, it is immediately connected by another signal line, continues to work normally, and smoothly connects.
4. Raw materials: All the raw materials of LED display are brand-name high-quality products. The most important LED lamps use high-quality LED lamps.
5. Three-level product aging process: Firstly, the module produced by the automated assembly line is energized and aging for 24 hours, then 48 hours of electricity aging is performed on a single box. Finally, the on-site assembled finished display screen is energized and aging for 72 hours. Shipped to the site where it is assembled.
