Samsung shows how its LCD TVs compare to LG's OLED TVs in terms of image retention

Oct 16, 2017

Samsung has published a video showing how 12 hours of gaming effects different TV technologies. Samsung compare's it's own Q-LED (quantum-dots enhanced LED LCD TV) with LG's OLED TVs (the 2017 OLEDB7).

The video shows that following the extensive gaming run, Samsung's TV shows no image retention (burn-in), while some problems are clearly visible on LG's TV.

CPT aims to start mass producing QD-LED displays within 2 years

Sep 26, 2017

Taiwan-based Chunghwa Picture Tubes (CPT) says that it is developing Quantum-Dots displays (QD-LEDs) produced using a printing process. CPT says that QD-LEDs offer pure-colors, long lifetime and are more efficient and stable compared to OLED displays.

CPT hopes that a printing process will enable low cost QD-LED displays. CPT's Material Technology Division manager estimates that the major obstacles have already been overcome - although the performance of quantum dots is still lacking and CPT is continuing to research and develop QD materials. CPT estimates that it could start mass producing QD-LED displays within two years.

IHS and DSCC seem to disagree on the future of QLED-LCD TVs

Aug 26, 2017

According to IHS, sales of quantum-dot enhanced LCD TVs, or QLED TVs, dropped 48% in Q2 2017 compared to Q1 2017. Total sales in Q2 amounted to only 351,000 units - down from 671,000 in Q1 2017. OLED TV sales, meanwhile, increased from 29% from 212,000 units to 282,000 units.

Following this report, Business Korea speculates that Samsung Electronics may have to change its premium TV strategy, as it faces market share lose in this very important segment and may lose its leading position in the total TV market.

Guangzhou New Vision demonstrates its latest flexible and foldable OLEDs

Jul 24, 2017

China's Guangzhou New Vision demonstrated its latest flexible and foldable AMOLED displays at SID DisplayWeek. According to the company in the video below, these displays will enter production in 1.5 years.

As can be seen in the video, the company is developing flexible OLEDs with a resolution of 400 PPI on oxide-TFT backplanes and Polyimide substrates. New Vision also develops printing technologies (for both OLED and QLED displays, interestingly) - but these are still in an early stage, it seems.

Digital Trends: LG's OLED TV outperforms Samsung's QLED

Jul 01, 2017

Digital Trends posted that interesting flagship TV shootout, pitching LG's E7 OLED TV against Samsung's Q9 QLED TV. Both TVs offer great image quality, and both has their strengths and weaknesses - but Digital Trends says at the end of the day they prefer LG's OLED.

According to Digital Trends, pretty much everybody who looked at these two TVs stacked up against each other chose the LG as the best TV - if by a razor-thin margin. Credit is due to Samsung, who did manage to produce a very bright, sharp and great looking TV though.

BOE's new OLED, LCD and QD displays from SID 2017 shown in video

Jun 22, 2017

Last month BOE demonstrated several exciting new display technologies at the SID DisplayWeek, and now we have this very nice (and long) video that shows most of BOE's new displays.

We start with a tablet-phone device, a 7.56" foldable touch-enabled OLED that features an QXGA (2048x1536) resolution, a bending radius of 5 mm and a contrast rate of over 70,000:1.

BOE demonstrates Q-LED display prototypes

May 30, 2017

Last week BOE demonstrated two Q-LED displays, 5" (320x240) and 14" (960x540). These prototype displays use electroluminesence quantum-dots as emitting materials.

According to BOE, switching to an in-organic emitter enables a display that features an excellent display quality - on part with OLED displays - while also being compatible with ink-jet printing, which will enable QLED displays to be lower-cost compared to OLEDs.

Nanoco and Kyulux to co-develop hybrid OLED / QLED display technology

May 22, 2017

Hyperfluoresence and TADF OLED emitter developer Kyulux and quantum-dot developer Nanoco announced that the two companies will co-develop a future-generation hybrid OLED / QLED display technology that combines Kyulux's hyperflourescent emitters and Nanoco's heavy metal free quantum dots (CDQDs).

Kyulux and Nanoco say that future displays based on this technology will have superior qualities compared to existing displays - high degree of brightness, energy efficiency, color purity and low cost.

DSCC sees 6.8 million OLED TV panels sold in 2021

Jan 05, 2017

Display Supply Chain Consultants (DSCC) released a new free white paper (sponsored by Nanosys, a quantum-dot producer) in which it analyses the premium TV market and compares the future of OLED TV to that of QD-LCD TVs.

OLED and QD TV penetration (2016-2021, DSCC)

According to DSCC, the total TV market will grow from 261 million units in 2016 to 282 million in 2021 - a slow CAGR of 1.6". The OLED TV market will grow at a rapid rate of 50% - from 0.9 million panels in 2016 to 6.8 million in 2021. Even at this fast growth rate, OLEDs will represent only 2.4% of the total TV market in 2021. The main constraints towards faster OLED TV growth, according to DSCC, will be production capacity and not demand.

Impressions from a visit to StoreDot

Dec 11, 2016

StoreDot was established in 2011, to commercialize bio-organic quantum dots based on a process developed at Tel Aviv University. The company's first product was to be a memory device - hence the name StoreDot. In 2013 I visited the company in its Ramat Gan office to report on its quantum dot advances for display applications.

Since 2013, a lot has happened at StoreDot. The company changed its direction and is now focused on a new organic-material synthesis method that enabled it to develop nanomaterials that exhibit quantum dot like performance but that are not actually quantum dots. The company is now targeting two applications - fast charging batteries and displays. StoreDot has moved to large offices in Herzelia, has now over 60 employees and raised over $60 million dollars (led by Samsung Ventures). The one thing that did not change is the name - even though the company is neither into memory devices nor quantum dots anymore...
