Technology is a powerful driving force for the rapid development of LED industry, and it is also the confidence and strength for Chinese LED enterprises to stride onto the world stage. Driven by technological innovation, LED enterprises are showing the strength of Chinese smart manufacturing to the world. Watch eight LED hot technology, prospects and "money" which strong? What are the opportunities and challenges ahead?

Small spacing LED: technology is constantly refreshing, the market ushered in the outbreak period

LED display with small spacing refers to the indoor LED display with LED dot spacing less than P2.5, which mainly includes LED display products such as P2.5, P2.0, P1.9, P1.8, P1.6, P1.5, P1.2, P1.0 and P0.8. The appearance of small spacing has greatly improved the resolution of traditional LED displays.

Thanks to a strong push from industry players, the small-spacing LED display technology made great progress in 2015, with the minimum point spacing reaching 0.7mm. LED display products with small spacing of 0.9mm dot spacing have achieved mass production. From the technical level alone, the small space LED display technology has been able to fully meet the market application demand, even has walked in front of the market application demand.

The small spacing LED has the characteristics of seamless stitching, natural color reality, ultra-high gray scale and so on, especially the exquisite and true color display created by ultra-high gray scale, and the brightness can be adjusted at will to make it suitable for any display environment. In addition, it has mature point-by-point correction technology, which is quite convenient for later maintenance. Compared with the traditional LED display, the small spacing LED display has smaller dot spacing, greatly improved resolution, and more and more clear and delicate display picture, which lays a good foundation for its entry into the indoor.

After two or three years of preparation, small spacing LED is expected to usher in the outbreak period in 2016. LED display with small spacing has been widely used in military industry, broadcasting, command and dispatch and other government projects and high-end commercial areas. In the future, when the technology of small spacing is perfected, and the cost is also controlled accordingly, its acceptance and demand in the market will be greatly improved, and its application scope will be more and more extensive. At that time, it will gradually transition to the civil field.

LED filament lamp: technology is becoming mature, the market is concentrated in Europe and America

LED filament lamp is a crossover product, both energy-saving lighting function, and highly decorative. For a long time, filament lamp suffers from heat dissipation difficulty, low power and high price, which is also the reason for its long-term not by the market. Until the second half of 2015, the LED filament lamp technology bottleneck was broken with the intervention of linear constant-current driven IC, coupled with the chip, packaging device, phosphor, substrate and other materials and equipment gradually mature matching, the development of filament lamp rose to a new stage.
