KUALA LUMPUR: A research team led by Professor Hsueh-Shih (Sean) Chen of National Tsing Hua University (NTHU) has developed a new quantum dot material, more stable with a more realistic colour.
The main limitations of the current quantum dot display materials are that they are unstable and easily damaged. The team has rectified this by growing ‘shield’ with approximately one-nanometer at the crystal facets of each quantum dot.
Inspired by the shield used by comic book superhero Captain America in the Avengers series, Chen hit upon the idea of giving each quantum dot its own shields about one nanometer in size, which effectively resists water and oxidation and also increases material stability and the display’s lifespan.
Chen’s unique shield technology that protects the quantum dots will significantly reduce production costs.
According to NTHU in a statement, the new material has a wide range of applications, including the screens used in televisions, computers, mobile phones and cameras.
With NTHU support, the team has already applied for patents for the new material and has established the HsinLight Inc to produce it on a commercial scale.
It is expected that the first quantum dot screens will begin production this year. – Feb 19, 2020, Bernama
