Tongtong has a PhD in Materials Science from Cambridge University and a diverse background of physics, electronics, engineering and materials science, and many years’ experience in the field of III-nitride semiconductor materials and devices since 2008. With expertise in materials deposition techniques, and multidisciplinary skills in the development of material science and device applications across a range of fields, he has developed numerous new materials and structure production processes whilst progressing the general community understanding of the science of materials growth.
Porotech have delivered an innovative advancement in microLED technology in the form of DynamicPixelTuning® (DPT®) – a world first for LEDs, enabled by our engineered porous GaN (PoroGaN®) platform technology. Here, each individual DPT® pixel is a single microLED emitter whose emission wavelength can be tuned all the way from red to blue and beyond, as dictated by the end application. For multiple or full colour microLED displays, this removes the need for ‘RGB’ sub-pixels made from different material systems and no further colour conversion/filtering or complex stacking architectures are required. This removes key manufacturing roadblocks and simplifies system design to deliver high performance microLED display & optical module solutions across the whole display industry.
