Quantum Dot Display Technology Set To Enter Mainstream Markets

New report forecasts rising use of quantum dot displays for smartphones and tablet PCs

According to NPD DisplaySearch's latest market research on quantum dot displays, by 2015 3 percent of smartphone TFT LCDs will use quantum dots, growing to 26 percent in 2020. In tablet PCs, the figure will be nearly 2 percent in 2015, growing to 15 percent in 2020. For LCD TV,  the company forecasts that less than 1 percent of LCD TV screens will use quantum dots in 2015, growing to 9 percent in 2020.

"Quantum dot solution prices remain high compared to other more entrenched technologies," said Yoonsung Chung, general manager, NPD DisplaySearch Korea. In 5in smartphone panels, the cost of panels using sheet-type on-surface quantum dots is 20 percent higher than typical TFT LCD smartphone panels. As the display size increases, so does the cost, with the premium for a 55 in TV panel estimated to be 35 percent.

Quantum dot provides a colour gamut exceeding the National Television System Committee (NTSC) colour specifications; typical TFT LCDs achieve only up to 75 percent of NTSC. However quantum dot technology has several problems, including reduced durability, higher cost, and restrictions on the use of cadmium and other heavy metals in household products.

"Display makers have shown interest in adopting quantum dot technology, but they have been concerned about heavy metals and higher prices," Chung noted. "Recently, however, the European Union has offered a temporary exemption for the use of cadmium-containing quantum dots in displays. Cadmium-free quantum dot materials have also become available, so display manufacturers are taking a fresh look."

NPD DisplaySearch' s Quantum Dot Technology and Market Forecast Report provides global market research on the benefits, challenges, makers and market drivers that affect the adoption of quantum dot technology.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
