Quantum Dots - Page 8

Automotive component maker Harman (owned by Samsung) is demonstrating new automotive display prototypes and designs that make use of Samsung's latest displays - both OLEDs and QLEDs.

The new automotive designs includes Samsung's latest flexible and transparent OLED displays, and Harman hopes that these new designs will bring more choice and flexibility to auto makers. Harman displayed two different car concepts which you can see above and below. In these concepts the OLEDs are used for the instrument cluster and other parts of the car, while the QLED panels are used for the infotainment system.

UBI Research is tracking the price of premium TV sold on Amazon.com in the US. As competition intensifies, the price gap between OLED and LCD TVs keeps getting lower - to the point where is not much difference between a high end Samsung QLED TV and LG's OLEDC7 OLED TVs.

In December 2016, the price gap between a 65" LG OLED TV to a 65" Samsung SUHD TV was about $1,000. The price gap as of today is only about $300. The price gap for a 55" TV is even lower (around $200).

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, while some problems are clearly visible on LG's TV.

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.

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.

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 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.

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.

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.

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.
