LED lighting industry technology development trend is good

In the field of traditional LED display screen, the key technologies of various indoor and outdoor LED display screens are basically mature. The whole machine of the products has been continuously improved and perfected in terms of reliability and technological level, forming a standardized series of products. The overall technological innovation direction of the industry mainly focuses on large screen control, new product development of high-density display, special-shaped engineering design of special projects, LED display application expansion products, product reliability, energy conservation, etc. At the same time, full-color indoor and outdoor display screens are widely used, and outdoor high-definition full-color display technology and products are becoming more and more mature. With the continuous innovation of technology, the development of LED upstream industry plays an obvious role in promoting the development of display application industry, and the comprehensive technical engineering capability applied to major projects and meeting special needs is enhanced. Indoor high density, small pitch LED display challenges DLP rear projection, LCD, etc. , from P2. 5 to P1. 8 again to P1. 5, widely used in radio and television, road traffic command, public security monitoring, power system, military, water conservancy, urban management and other industries. At the European Cup in June 2012, Chinese LED display enterprises once again demonstrated the elegant demeanour of Chinese LED display products, and once again made Chinese manufacturing stand at the center of the world stage. In the Spring Festival Gala of 2012, the 360-degree dream stage composed of LED display screen presented a visual feast. Therefore, the demand for materials and devices in the whole industry has also undergone new changes. In terms of chip devices, the demand for surface-mounted devices is continuously increasing, and wavelength dispersion is required to be small and color consistency is strong; Strong antistatic ability and high reliability; High cost performance and easy cost control. In terms of driving components, there are higher requirements for refresh frequency and intelligent control. In terms of power supply system, energy saving and reliability are required to realize redundant backup.
