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.

Light is not just light, gpiled mixes and matches LED CSP dual-color temperature, high CRI, and R9 into a light panel with adjustable temperature. The advantages of LED CSP are small size, high power, and can be densely stacked, dimmable, which is different from the traditional overlay phosphor COB. It is suitable for applications that require high lumens per unit area and high color rendering, such as photography lights, Video lights, etc.

GPILED's DCOB adopt the AlN  substrate and CSP tech to have the lower heat and higher lumen with outstanding CRI and R9.

Car ADAS Headlight and HUD:ADB Pixel light and HUD AR Patent


GPILED has developed data sensing, processing, and control of digital light output over the past ten years. Among them, the intelligent control of vehicle lights, HUD, and intelligent lighting and AR applications have related technology patent layouts.

AR HUD can achieve augmented reality. A very important factor comes from the fact that AR HUD has a wider field of view than other HUDs. The HUD's VID (Virtual Image Distance) and FOV (Field of Vision) are two indicators. VID (Virtual Image Distance), the distance from the human eye to the virtual image; FOV (Field of Vision), the angle at which the virtual image can be presented with the human eye as the starting point.

Generally speaking, when driving, most of the distance you can see is more than 2.5 meters of traditional HUD, but the virtual image distance of traditional HUD is about 2.5 meters, which means that when driving and reading the information on the HUD, the eyeball needs to be zoomed to a shorter distance. The state of the car also brings additional doubts to the safety of driving. Generally speaking, AR HUD hopes to achieve a VID distance of 10 meters and a FOV angle of 10 degrees. This is why we think it is not feasible to use micro LEDs to make windshields.

Inductive technology thinking of  Micro led market 

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.

For micro LEDs topic, the massive transfer of two different materials has not been considered the main solution. Micro LED faces more challenges than the media, although the life time of LED is longer than OLED. However, the luminous attenuation of RGB three-color LEDs is still worse. The reliability of the reduction of red light is likely to run away after a short period of use. The brightness and color of each RGB LED may have a gap, and it is very difficult to control the quality to a small difference.

what is the next of LED ?

1. As to red material issue

Therefore, we have developed the 3 color micro LED tech by Blue, Blue plus QD Red, Green nitride micro LEDs resolving the red material and with specific lens structure design to make the pixel light to reach a good color quality and issue in 2012 Patent . 

2. The target market

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
