TCL has come under scrutiny this month after testing that claimed to examine three TCL TVs marketed as quantum dot TVs reportedly showed no trace of quantum dots.

Quantum dots are semiconductor particles that are several nanometers large and emit different color lights when struck with light of a certain frequency. The color of the light emitted by the quantum dot depends on the wavelength, which is impacted by the quantum dot's size. Some premium TVs (and computer monitors) use quantum dots so they can display a wider range of colors.

Quantum dots have become a large selling point for LCD-LED, Mini LED, and QD-OLED TVs, and quantum dot TVs command higher prices. A TV manufacturer pushing off standard TVs as quantum dot TVs would create a scandal significant enough to break consumer trust in China's biggest TV manufacturer and could also result in legal ramifications.
