1, material selection:
Without a good raw material to ensure product quality can not be. Therefore, the selection of raw materials, all key components of our suppliers, brands have carried out strict selection, including -
(1) LED light-emitting devices (LED): This is the most important parts of the external screen rooms, our company is to ensure the quality of products used in all the world's best brands of chips.
LED Selection:
The average brightness of the LED center wavelength of the brand perspective
Red 800-1000mcd110/40Deg625 nm Guanglei Taiwan
Hangzhou Silan pure green 1800-2200mcd110/40Deg525 nm
Hangzhou Silan Pure Blue 500-800mcd110/40Deg470 nm
Brightness of red, green and blue color ratio R: G: B = 3:6:1 (WB)
(2) PCB: UL standard strictly in accordance with the United States for production.
(3) integrated circuit (IC): the United States ST, Philips, Hitachi.
(4) Power Supply: Power Supply with LED display.
(5) communication lines: the United States AT & T Inc. (model: five).
(6) connector: AMP U.S. (AMP), Inc. (Model: 16P).
2, sorting of raw materials:
This is the production process, a very important part. Because, even the world famous manufacturers of chips, the performance parameters of the distribution also has some form; Therefore, in the production process and must be scientific and rigorous testing and sorting. The only way to ensure that the indoor screen in the visual sensory area, with good uniformity; in electrical performance, good stability and consistency.
3, the semi-filter:
Taking into account the light-emitting components in the processing of the process, will be subjected to mechanical and temperature of the strike, the performance of some components will be affected, resulting in a decline in some indicators; Therefore, in the production of intermediate links, we has set up testing, aging And elimination process in order to avoid the difficulties of testing finished products.
