Shenzhen Optoelectronic do Zweig LED display manufacturers advantages: 1, the quality advantage: has experienced technical team, R & D team and installation team, advanced international pipeline, the raw materials through strict quality checks, 2, the performance advantages: I Division LED electronic display using micro-computer control, so illustrations to real-time, synchronous, clear play all kinds of information, but also can display two-dimensional, three-dimensional animation, video, TV, VCD programs, and live, colorful screen, three-dimensional sense. 3, the price advantage: the industry's most cost-effective, LED electronic display as low as 39,000 yuan, allowing you to fully experience the stop price 4, energy saving: low power consumption, high brightness, low voltage, low power consumption , miniaturization, easy to match with the integrated circuit, driving a simple, long life, impact resistance, stable performance 5, service advantages: a more perfect pre-sale, sale, service, two years of free warranty and lifetime maintenance to Zweig photoelectric world-class sophisticated detection equipment and production equipment to ensure good quality products. After years of development, quality control and management processes to maintain its leading position in the domestic LED industry. 1, Zweig photoelectric full color display LED (light emitting tube) is used: <1> The same display of red, green and blue light-emitting diodes each use the same grade (the same height, the same wavelength). <2> The red, green and blue tubes in strict accordance with the ratio of display brightness R: G: B = 3: 6: 1. <3> in cooperation with well-known brand, chip Silan, Opto Taiwan, Xiamen Sanan, US CREE or Nichia. 2. Reliability test: In order to avoid the production of photovoltaic Zweig, design products appear recessive defect, developed a series of reliability testing. <1> Semi-finished electrical performance test, before the semi-finished modules sealant, after QC test completely OK, pass on all products power high-temperature aging for at least 48 hours. <2> finished aging test, the finished LED module is mounted on the housing, and the entire screen assembly simulated field, through no fault aging test 72 hours before they can be shipped. <3> waterproof test, outdoor full color LED display screen body adds to the high-pressure flushing test, and each box were invading water and water spray test, in order to ensure the waterproof effect. <4> corrosion test, Qualcomm & Poor's to ensure that after the board repeated handling, chassis corrosion reliability in the production process must be salt spray test. <5> vibration test, traffic guidance for outdoor full color LED displays, automotive LED full-color large screen, shipboard outdoor full color LED display and a removable LED full-color electronic display, often in shock because of their work conditions In order to ensure product reliability, vibration test must be carried out. <6> environmental laboratory, Qualcomm & Poor's outdoor full color LED display debugging real outdoor environment, to ensure consistency with the field effect factory effect.
