Samsung quantum dot displays: half the cost of AMOLED and last longer ‎

The future of Samsung displays will be centered around quantum dots. These semiconducting nanocrystals are illuminated by current or light and promise to be brighter, cheaper and more energy-efficient than either LCD or AMOLED displays.

Here’s the scoop. Quantum dot displays consume less than a fifth of the power of LCDs and promise to be brighter and longer-lasting than OLEDs. This is a deadly combination before you even consider that they can be manufactured for less than half of what it costs to make either display today.

So how does it work? The full-color quantum dot display is controlled by an active matrix with each of its color quantum-dot pixels is turned on and off with a thin-film transistor. For now, there have been two prototypes created: glass and flexible plastic. The goal is to incorporate the technology in TVs, mobile phones, MP3 players and any other gadget with a display.

Samsung is not the only one planning to make use of quantum dot displays. LG has reportedly partnered with QD vision to develop their own sets. For now, Samsung has the edge since they are the first to demonstrate a full color display with quantum dots.

Before you start expecting to see quantum dot displays in next year’s mobiles, Samsung has been very clear that the technology is still three years away from commercial roll out. The current dilemmas researchers face are related to extending the life of the displays and improving their power efficiency. Nevertheless, it never hurts to get a peak at the future and salivate over the possibilities, right?
