QD is based on organic light-emitting diode (OLED) technology and is considered more advanced than liquid crystal displays (LCDs). The semiconductor particles luminate close to natural colours, offering enhanced brightness and colour.

The company showcased the Q6, its newest model, which delivers high-definition colour and 66% higher brightness compared to standard LCD TVs. Its high-end Q7 model has doubled its peak brightness from the company’s QLED TV from last year.

Conventional TVs add colour when light passes through filters, but QDs can easily produce rich colours because the particles themselves emit colours independently. QDs have the property of greatly diffusing light, allowing it to shine in all directions.

TCL said that both the Q6 and the Q7 have a function to optimise gaming. Scott Ramirez, TCL North America’s vice president for product marketing and development, stressed that the TVs are “suitable for all applications, including movies, sports and games”.

Global electronics companies are racing to stay ahead of the game. Sony and Samsung have also produced QD-type TVs.
