The beginning of the procurement of raw materials to the production and installation of the standardization and standardization of the use of LED display life will have a great impact. From the chip, lamp beads and drive IC and other electronic components, to the quality of switching power supply, which are the direct impact of LED large screen life of the direct factors, but often also by the purchaser ignored. When we plan for the project, we should specify the use of reliable quality LED lights beads, good word of mouth switching power supply, and other raw materials, specific brands and models.
Good chip is the basis of light beads stability, should use high-quality light-emitting chip as the core material. Lamp beads as the most critical parts of the LED display of high quality requirements, lamp beads to be stable use, must have high reliability and high performance of the two prerequisites. High-quality lamp beads require each batch of products to be high temperature and humidity, high temperature aging test.
Driver IC is the real "small body big effect", anti-"caterpillar", to eliminate the hidden, high refresh, high gray scale, excellent low gray balance all rely on the driver IC to solve. High-quality driver IC for full color led display in brightness, grayscale, contrast, high density, viewing angle, stability, color uniformity, color saturation, image edge of the delicate degree, smooth video effects, and so played an extreme advantage.
Power supply is also very important, because the power supply in different temperature conditions, its work stability, output voltage and load capacity will be different, because it is responsible for the role of logistics support, so its security capabilities directly affect the screen quality.
In addition, the LED display can receive the normal signal and display can not be separated from the LED display controller, divided into asynchronous and synchronous two ways. Excellent controller can maximize the loss of the signal to avoid and improve the consistency of the display, the entire screen without any color patches appear.
