A new kind of display is about to make TV images appear even more lifelike. LG will show off a TV based on quantum-dot technology at CES 2015 in January, and the company also plans to start selling it later that year.
Quantum-dot tech uses extremely tiny crystals — measuring 2 to 10 nanometers — to generate light. (That’s so small that the tiniest crystals are only about 20 atoms thick.) Different-size crystals generate different colors, and the size of the crystals can be controlled precisely. As a result, quantum-dot displays can reproduce color that’s even better and more accurate than OLED screens, the current leading tech for advanced TVs.
