Reuters reports that LG Electronics decided to develop Quantum-Dot LCDs. In the long run LGE still sees OLED as the superior technology, but QD does provide "tangible benefits" for its current line of LCD panels.
Only a few days ago the Korea Times reported that Samsung is set to introduce the first cadmium-free QD TV in 2015. Samsung is collaborating with Dow Chemical on those QDs, and according to Korea Times LG is also working together with Dow on cadmium-free QDs.
LCDs enhanced with QD films offer a wider color gamut and are more efficient compared to 'regular' LCDs. So-called QD-LEDs match the color performance of OLEDs, and so may challenge OLED TVs, at least until OLED panel prices come near those of LCD panels.
