SSL China 2016:LED industry is the new trend of MicroLED, laser, LiFi......

The thirteenth Chinese International Semiconductor Lighting Forum (SSLChina) and the third generation semiconductor International Conference (IFWS) on November 2016 15-18, held in Beijing International Conference Center, carry out science and technology innovation planning Chinese 13th Five-Year national implementation of strategic support, advanced electronic materials special focus. LEDinside have the honor was invited to participate in the meeting, all the key trends in record industry experts published the day set the next five years will be more focused on the key industry cross industry applications, including MicroLED, VCSEL, LiFi laser, laser light and visible light communication, intelligent lighting and healthy lighting.

MicroLED

The first day of the opening ceremony of the focus of the meeting, the 2014 winner of the Nobel prize for physics, the United States Department of Materials Engineering College of University of California-Santa Barbara Professor Mr. Nakamura Shuji mentioned the new trend of three key industries including LED, MicroLED, LiFi laser lighting, etc.. Among them, compared to OLED, MicroLED eliminates the filters and polarizers, with better brightness and energy efficiency, while the product life is also longer than OLED. The application of display, pixel size (Pixel Size) is one of the most important indicators to 300-600DPI on the display screen, the pixel lateral size (Lateral Dimensions) is about 10 m; the display screen of more than 1000 DPI, (Lateral Dimensions) pixel lateral dimensions need to be smaller. However, MicroLED is facing to the fundamental and most important issues, first, the efficiency of the MicroLED, the chip size also affect the performance of EQE MicroLED, the chip size is quite small, the current spreading (Current Spreading) in the area is very small, compared to the current density is high; second, MicroLED selection and transfer of technology.

Laser illumination

Mr. Nakamura Shuji said the current density (Current Density KA/cm2) more than LED EQE, the laser performance to better laser lighting has been widely used in micro projector, projector, more than 100 inch laser TV, laser headlights, headlight can only be compared to LED irradiation 300 meter, laser lighting can reach 600 meters.

LiFi

LiFiCentre compared to WiFi, LiFi using LED or laser has better transmission capability for sensing, warning or consumer preference data analysis. In LED technology, compared with the white light LED excited by phosphor, MicroLED and RGB laser have better optical transmission function, which can reach 10Gbps and 100Gbps, respectively. Lighting combined with wireless communications and handheld applications such as mobile phones and other lighting market to bring different opportunities for development. LiFi and visible light communications are expected to reach $115 billion in 2022.

VCSEL laser

With the car factory and sensor manufacturers actively develop automatic auxiliary driving system, is expected to 2030-2035, and Chinese will become the main use of state, then, VCSEL will become the main way of laser sensing, data transmission and market demand (Datacom), VCSEL manufacturers to actively expand production, the major manufacturers including Finisar, JDSU, Philips, Photonics Rohm, Lumentum, Hua Lijie etc..
