Compared with the more common OLED screen now, quantum dot LED screen has no small advantage, but the production of heavy metals containing a lot of lead is not environmentally friendly, April 29 according to Japanese media reports, Japan's Hiroshima University recently developed a new type of quantum dot LED, using rice shells to make non-toxic environmental protection, let's take a look at it.
The backlight using quantum dot LED (Quantum Dots") material is the purest color backlight at present, and the quantum dot TV uses the purest color quantum dot light source as the backlight, which revolutionarily realizes the full color gamut display and the most realistic restoration of image color. Therefore, quantum dot TVs are called by the industry to replace OLED better TVs.
The research paper of Hiroshima University was published in the journal of the American Chemical Society "ACS Sustainable Chemistry & Engineering", which is simply to extract about 20% of the glass components contained in rice shells to make quantum dot LEDs, which has a huge advantage of non-toxic environmental protection over traditional heavy metal materials such as lead, and may be put into actual production in the near future.
