The Nobel prize winner developed Nanorods LED for future display

At the Display Week 2018 exhibition, the popularity of Micro LED can be seen from the theme report (Keynote Speech) on the opening day of the conference. This theme report, in addition to CEO Zhang Deqiang, explores the technical prospects of OLED displays. Oculus Research's Douglas Lanman, and Ph.D also explored the eye tracking technology on the VR device.

Among the professionals and experts in the field of display, the SID also invited the Nobel prize winner and the Nagoya University professor Amano Hiroshi (Hiroshi Amano) to share the development trends of Micro LED technology in the future.

In addition to future LED application prospects in various energy saving fields, Professor Amano Hiroshi has also discussed the Nanorods LED in the field of display, and believes that the technology will have a chance to become one of the possible options in the field of display. In particular, when the display resolution of future consumer electronics needs to be pulled up to 8K, the size of Micro LED chip needs less than 1 u m to meet the screen size of the mobile phone. Whether it is using QD or phosphor, it will be quite large to apply these materials for light and color conversion on such a small chip. Technical barriers.

Therefore, the technology team in Japan is currently working on Nanorods LED research, hoping to grow RGB three different light colors through the Nanorods LED directly on the chip structure (such as the diagram below).

Of course, this technology will completely subvert the existing LED production process. Therefore, the equipment that includes the growth of epitaxy needs to be changed, and the growth of epitaxial structure requires the growth of the epitaxial structure of the heterostructure through the injection and interruption interlace. In the hope of this, the full color RGB light can be realized in a single chip. So when can black technology like outer space come true? Let's pray for a lifetime. (LEDinside Roger)
