The product produced, the surface-mount screen automated high, it can be produced by automatic placement equipment, led, has a very high efficiency, and its cost is also a lot cheaper. On body weight, a very light, led electronic display, which uses aluminum alloy and its housing materials have a great relationship, not only lightweight, but also very beautiful, after prolonged use, will not There deformed generation, whether it is the product for rental companies, or to purchase and have a very high value. 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, the screen should be pure white, led full color, without any other noise. If you think a little reddish or bluish does not matter, you're wrong, because the cast to prove this display materials and quality control processes have problems. Use a long time, led manufacturers, will become increasingly 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, 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. led manufacturers | Gao Jin photovoltaic (Online) | led by Jinan Optoelectronics Technology Co., Ltd.
