In order to check the quality, for the customer's needs, we introduced a number of sets of the entire SMT production line equipment, optimization "triple play" surface mount technology to achieve a high packing density, small volume, light weight, light patch element thin and so on. Zweig Optoelectronics Technology Each outdoor full color display are automatically inserted through automatic plug lights, in order to ensure on each lamp module is not crooked not inclined to ensure a uniform shine Screen does not appear polarized bias color, partial visual phenomenon. And in the production process are strictly from raw material into a product of each procedure, in strict accordance with ISO9001: 2008, and 7S control environment, anti-static dust so hard; and based on its own strength and world-renowned LED materials strict requirements to achieve the strategic partnership providers such as America CREE, Opto Taiwan, Japan NICHIA, etc., from the source to begin to control product quality, "quality is life", so that our products in the market share remains high: 1. Long-term testing and simulation environment of high temperature Zhengkao good feedback, frozen, flooding dust spray and other customers have expressed our outdoor full-color LED display products can be adapted to a variety of outdoor environments, under normal outdoor environment life can be more than one hundred thousand hours 2. Protection level reaches IP65, box compression resistance, impact resistance are outstanding 3. Humane lock, handles and other lightweight design makes your installation easier and faster 4. Multi-mode display, user-friendly operating system, a school will let you!
