LED electronic display screen driven by the low voltage scanning, power saving, long service life, low cost, high brightness, big Angle of view, the visual distance, and the advantages of waterproof, specifications varieties, can satisfy the requirements of different application scenarios, development prospect is very broad, is recognized as the most potential for growth is one of the fastest growing market of LED applications. And new demand such as the large sports events in the future, will be to promote large-scale development of LED display. In addition, has set up a large LED display screen will every 10 years after a replacement, as people living standard rise, outdoor LED display will be gradually applied in various industries.
The following shenzhen terence electronic co., LTD., a simple introduction for you the correct evaluation of LED electronic display techniques of quality:
1. Control points out of control points is not more than three over ten thousand of the indoor LED display, outdoor LED display control points should be not more than three over one thousand, and the discrete strong;
2. The consistency, LED screen, the whole screen brightness to equilibrium, no obvious color piece;
3. The security No safe hidden trouble, leakage current, the floor drain current shall not exceed 3.5 mA (ac RMS); The point of strength, the LED display can be 50 hz, 1500 v (ac RMS) experiment voltage Lmin should not occur insulation breakdown; At the same time LED display in fuse and switch power supply should be warning signs;
4. The appearance, LED display frame has no obvious scratches. Outdoor LED display pixel pipe installation should be consistent, not loose and shell burst;
5. The structure, LED display part can use materials such as steel, aluminum, wood, require solid structure, beautiful.
