The method is simple: look at the power behind the number of cabinet, led, multiplied by the maximum power of each power supply, according to the size of the box you can calculate the maximum power meters, power general use, there are two, 200W and 300W power supply. Usually refers to the use of power is to play advertising video, text, pictures power, because the use of power and playback content has a direct relationship, it is difficult to have a precise value, but according to our experience, usually The maximum power consumption of 1/3. Lower power consumption on behalf of lower cost and smaller heat which depends on the current size, a direct impact on the life and stability of the display. How to use the easiest way to distinguish the quality of the merits of a LED display, LED wavelength control range of the wavelength determines the color is pure, the color is the same. Resolution solution is simple; users are generally not professional equipment, how to use the eye to distinguish? First: the entire screen play white, led electronic screen, the screen should be pure white, without any other noise. If you think it does not matter a bit reddish or bluish, led offer, you're wrong, because the cast to prove this display materials and quality control processes have problems. Use a long time, it will be more serious. Second: the play of red, green and blue color, the color of the center wavelength is usually we say Zhenglan being green is red, led module, if a bit deeper or lighter color, proved to be partial wavelength. If a color is inconsistent, proved to be too poor wave, high-quality display in the center wavelength range, the difference between blue and green wave control 3nm, the red wave is less than 5nm.
