New Breakthroughs In Optoelectronic Chips: Mobile Phones Or Real Night Vision Devices

Among the products released by many mobile phone manufacturers, Samsung's flagship series in recent years, because of the good quality of night imaging, has won the first name of the night vision device. Recently, the technological breakthrough made by Yunnan University may really make smart phones a night vision device.

According to the Beijing News reported that recently, the Yunnan University photoelectric Engineering Technology Research Center developed a new optoelectronic chip, the future can be mounted on the mobile phone, glasses and other commonly used tools, so that ordinary people can also have the function of "night vision".

It is reported that the optoelectronic chip developed by the photoelectrical engineering technology research center of Yunnan University is to integrate the infrared photosensitive material with two organic light-emitting diodes (OLED) in series. First, infrared radiation is used to absorb infrared radiation to produce light carrier, and then the light generation carrier is used to drive the OLED to produce visible light emission. The purpose of infrared detection and imaging is realized.
The chip can not only directly transform infrared radiation into visible light, but also capture electrons and holes induced by infrared radiation at the same time, making the conversion efficiency of infrared light to visible light break through, up to 5%, close to the theoretical limit of 6.5%.
