Samsung is still on the side lines regarding OLED TVs, and reportedly the company is aiming to produce quantum-dot enhanced LCDs soon. One of the problem with QDs is that they include Cadmium, and now the Korea Times says that Samsung is collaborating with Dow Chemical to develop cadmium-free displays.

According to the report, Samsung Electronics aims to introduce the first cadmium-free QD TV in 2015. Dow chemical already started to produce the cadmium-free QD materials in its Korean's plant.

Even though LG Electronics is mostly focused on OLED TVs, according to Korea Times they may also start producing QD LCDs, following Samsung's lead. LG may also use Dow's cadmium-free QDs. Sony already commercialized quantum-dots TV, and this is a far easier panel to produce compared to an OLED panel.

Samsung is also an investor in Israeli StoreDot, which developed its own peptide-based cadmium-free QD material. It's not clear how close to commercialization this technology is, but it holds promise in many technology sectors such as displays, memory devices, batteries and more.

Isn’t each subpixel self-emitting?

Does “QD LCD TV” here mean just extended color gamut and/or increased power efficiency (thanks to more pure colors in backlit), and NOT that each subpixel is a standalone self-emitting QD-based light source like OLED?

MT - yes, that's exactly what

MT - yes, that's exactly what is meant by a QD LCD TV. It replaces the white LED with a blue LED and a QD 'phosphor' layer that absorbs the blue light and emits white light that is more pure and thus is more efficient and enables a larger color gamut.

... emits red and green light
