Electronic Design: What's the Difference Between Display Technologies?

Consumers shopping for a new TV or mobile device today are faced with a wide array of display technology options. From curved vs flat to Quantum Dot vs LED vs OLED vs Micro LED... the choice is no longer as simple as LED vs Plasma. 

Yong-Seog Kim, President, Society for Information Display, is trying to get to the bottom of this question. To do this, he's reached out to the top technology companies behind the latest, greatest display tech to ask them directly "what's the difference between all these new display technologies?"

A compilation of Dr. Kim's interviews has just been posted at Electronic Design and Nanosys is the featured representative for Quantum Dots:

To get some insight into the state of the market and the potential impact of these display technologies, we tapped several industry experts, each of whom also made a case for his company’s individual approach:

What are the benefits of QD-LCD compared to OLED or other emerging display technologies?

Quantum dots (Fig. 2) improve the power efficiency, brightness, and color performance of LED LCD displays. This enables LCD to compete with and actually surpass OLED displays in a number of ways, with the key advantages being peak luminance, color accuracy and reliability.

Quantum dots are today’s most efficient light-emitting material. This means they emit more light for less power. In the market today, we’re seeing QD TVs producing more than 1,400 nits of peak luminance, which is more than double a typical OLED set. Far from being simply brighter, this extra luminance means QD TVs can more faithfully reproduce HDR content, which can contain values up to 10,000 nits. Consumers strongly prefer TVs with higher peak luminance for viewing in a typical living-room environment.
