Resolution options, pay attention to the back-end signal transmission matched to the small distance between the LED display, the smaller the dot pitch, the higher the resolution, the higher the clarity of the screen, led offer, but in practice, professional users want to build the best small pitch LED display system, the body's own screen resolution concerned while, led cabinet, should also consider the match with back-end signal transmission products. For example, in the security surveillance applications, the front-end monitoring system, generally include a video signal D1, H264,720P, 1080I, 1080P and other formats, but not market all fine pitch LED screen can support more than several formats video signal, so in order to avoid wastage of resources, led module, users in the purchase of a small pitch LED screen, we must demand options, should not blindly chasing the trend. LED display life is determined by many factors, but end of life by a number of factors that can be constantly continued life through the replacement of parts (such as switching power supply). The LED is not possible to replace the large quantities, and therefore, once the LED end of life, it means that the termination of the life of the display. We say that life LED life determined display, led, but not to say that life is equal to LED display life. Since the screen is not at work each LED work at full capacity all the time, the display in the case of normal play video programming, life of the display period should be 6 to 10 times the life of the LED, when LED Working at a small current life situation can be longer. Therefore, the choice of the brand of LED display life up to 50,000 hours. led module, led, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin.
