GaN tech &LED
Gallium nitride is a compound of nitrogen and gallium. It is a direct energy gap semiconductor of group III and group V. The ratio of aluminum and indium can be adjusted by organic metal vapor deposition (MOVPE) to produce light emitting diodes with wavelengths covering 220nm~620nm.
With the development of wafer technology, the size of nitride LEDs has also been scaled down to a size of 100um, or 5um, along with the development of applications. The technology supplemented by quantum dot phosphors allows gallium nitride LEDs to develop various possibilities for display,AR,MR,ADB applications.
With 20 years of gallium nitride epitaxial technology, genesis photonics inc(gpiled) provides blue, green, ultraviolet, and deep ultraviolet light, supplemented by flip chip technology, including mini LED, micro LED,QD technology and then develops a series of wafer-level packages used in lighting, handheld devices, white goods, UVC medical sterilization, UVA 3D printing , and automotive lighting,AR etc., providing customers with full range photoelectric integration services.

Inductive technology thinking of Micro led market
Generally speaking, people are accustomed to comparing with opponents. How to make inductive thinking to consider what to do in the future. So this will also lead to misunderstandings of thinking
When someone proposed to use tiny RGB chips to hold the TV, more people came in together to make the same investment but ignored the basic problem (display down sizing, challenge with PPI)
Due to the technical difficulties of reducing the pixel chip size and pixel pitch, since 2015 Micro LED can only achieve the target high resolution by increasing the screen size and relaxing the viewing distance.
In addition, because the micro led display chips required fo watches, mobile phones, and car displays have evolved from super-large displays through medium-size to small-size displays, the technical difficulty is constantly increasing. So far there is no manufacturer's product is mass-produced.
But not only to compete with white OLED , the Korea news released that Samsung display has a plan to promote the QD OLED to TV makers including Sony, Samusng,and china TV brand in 2021.
what is the next of LED ?
Let us look at the human eye's effect on smaller screens. Ppi requirements, return to the physical nature of the technology to see whether the current method is suitable for the solution of the display device?
Genesis photonics Inc (gpiled) facing the advent of the era of big data, the development of LED technology will be accompanied by a positive parabolic relationship between size reduction and digital control drive.
We asked ourselves, what will the world look like ten years from now? What kind of functions can LED have in that era to provide technological services?
In response to this trend, we will continue to invest in miniaturization research and development, but we have chosen a market where OLED is not widely concentrated, and the integration of miniature optoelectronics integrated technology
