The LED large-screen media also has an advertisement characteristic with high effective arrival rate, and the price is relatively low compared with the media delivery forms such as television and newspaper. These unique values ​​make full-color
LED display media a natural newcomer to outdoor media. Unlike traditional outdoor media, full-color LED displays are not just outdoor media, but they also have the characteristics and advantages of media such as TV. Moreover, the full-color LED display is not just an extension of pure outdoor media and TV media. It has a larger creative space and a three-dimensional space that interacts and communicates with consumers' time and space to meet individual needs and has a digital age. The concept is a unique form of screen.
We often have such problems when applying LEDs. LED screens work normally at the beginning of the product, but after a period of lighting, there will be dark light, flashing, malfunction, intermittent light, etc. Bring serious damage. The reasons for this phenomenon are:
1. When applying the product, there are problems with the welding process. For example, the welding temperature is too high, the welding time is too long, and the antistatic work is not done. More than 95% of these problems are caused by the packaging process.
2. The quality of the LED itself or the manufacturing process.
The prevention methods are:
1. Do a good job in welding process control.
2. Perform an aging test on the product. Aging is an important guarantee for the reliability of electronic products and is the last essential step in the production of products. LED products can improve performance after aging and contribute to stable performance in later use. LED full color screen aging test is a very important part in product quality control, but it is often overlooked and cannot be properly and effectively aged. The LED aging test is based on the failure rate curve of the product, that is, the characteristics of the bathtub curve, to improve the reliability of the product, but this method is not necessary. After all, the aging test is to sacrifice the life of a single LED product. For the price.
LED aging methods include constant current aging and constant pressure aging. A constant current source means that the current is constant at all times. If there is a frequency problem, it is not a constant current. That is AC or pulsating current. The AC or pulsating current source can be designed to have a constant rms value, but this power supply cannot be called a "constant current source." Constant current aging is the most suitable LED current working characteristic, and it is the most scientific LED aging method. Overcurrent aging is also the latest aging method adopted by manufacturers. It can be used for such aging by using constant current source with adjustable frequency and current adjustable. In order to judge the quality life expectancy of LED in a short time, and can pick out many hidden LEDs that can not be picked out by conventional aging.
Fiber Splice On Connector now available in SC, LC, or FC variants, which is catering for 250um to 900um, and 2.0mm, 3.0mm diameter single mode and multimode fiber types, including Multi-mode 62.5/125um and Multi-mode 50/125um.
