Zhijing Nanotech Quantum Dot backlight units (QD-BLUs) using perovskite quantum-dot film (PQDF)

Posted by Charbax – June 17, 2018

Zhijing Nanotech from Beijing, China, develops next-gen quantum dot backlight units (QD-BLUs) for wide color gamut QLCD technology, which contains perovskite quantum-dot film (PQDF) as a primary light-conversion component. The PQDF exhibits high light conversion efficiency, narrow emission peak, high integration and low cost. During Display Week, they demonstrated the wide-color gamut PQDF-LCD TV prototype, which was achieved by combining the blue-light emitting diode (LED) chip, red K2SiF6:Mn4+ (KSF) phosphor, and green PQDF as RGB backlight sources. The luminance is above 500 nits.

Filmed at the I-Zone demo and prototype area at SID Display Week, the world's largest and best exhibition for electronic information display technology.

Display Week’s I-Zone, sponsored by E Ink, is a unique exhibition-within-the-exhibition filled with demos and prototypes from around the world. Every year, dozens of applicants submit their pre-market and emerging products to compete for a free booth where they can share their inventions with buyers, manufacturers, potential partners, industry leaders and thousands of attendees.

Nanosys Quantum Dots for LCD, OLED and MicroLED

Posted by Charbax – June 11, 2018

Jeff Yurek, Nanosys Director of Marketing at SID DisplayWeek 2018 in Los Angeles talks about the Quantum Dots which Nanosys has been developing since its founding in 2001. Jeff walks me through the company’s technology roadmap to explain how Quantum Dots can be used in displays of all types from LCDs to OLEDs to microLEDs and even emissive Quantum Dot displays of the future.

Quantum dots are tiny man-made crystals. They are so small that you can’t see them with a typical microscope. In fact, they’re 10,000 times narrower than a human hair. Quantum dots are actually very powerful devices and it’s their size that gives them a unique ability: to convert light into nearly any color in the visible spectrum with very high efficiency.

Each quantum dot is actually a tiny semiconductor -- which means it can convert incoming energy. The electronic characteristics of quantum dots are determined by their size and shape. This means they can control the color of light given off by a quantum dot just by changing its size. Bigger dots emit longer wavelengths like red, while smaller dots emit shorter wavelengths like green. Think of a guitar string. When a guitar string is shortened, it produces a higher pitch and when it is lengthened, it creates a lower pitch. The tune of a quantum dot – the wavelength of the light it emits – behaves in a similar way.

Today, Quantum Dot displays are built just like LED displays. The quantum dots are added to the backlight of the display in the form of a translucent plastic film that’s loaded with dots. Each TV contains literally trillions of Quantum Dots. In this mode, the Quantum Dots are improving existing LED displays by enabling them to be more power efficient and deliver better color.

The film itself is made using a roll-to-roll coating process. Nanosys manufactures Quantum Dots in Silicon Valley, California and partners with companies like Hitachi Chemical to create Quantum Dot films used by display makers.

Unlike OLED materials, Quantum Dots are inorganic. This means they’re really stable and can be handled more easily in manufacturing. That makes for a tougher, longer lasting display that doesn’t exhibit burn-in issues.

According to Nanosys, Quantum Dot technology is not limited to LCDs. It can improve displays of all types from LCDs to OLEDs to microLEDs to pure, emissive QDEL displays.

Nanosys shared a detailed roadmap video at SID that breaks down the display design for each of these new implementations for their future of the Quantum Dot.

Working with Gemalto, Qualcomm demonstrates Integrated SIM (iSIM) on their Snapdragon 850 trusted secure hardware element, to be able to select, load Telecom packages full securely, perhaps eventually also load and store any SIM card into the device and switch between each one.

Dr. Yamazaki, President of SEL, inventor of CAAC-IGZO and the basic element of Flash memory

Posted by Charbax – June 4, 2018

In 1970, Dr. Shunpei Yamazaki invented the basic element of flash memory, now widely used for storage everywhere. Shunpei Yamazaki holds the Guinness World Record for the most patents credited as inventor, at 11,353 as of 30 June 2016. At present, he is the president of Semiconductor Energy Laboratory (SEL) and is energetically doing R&D on many different advanced technologies with his team. His present R&D theme is the crystalline Indium-gallium-zinc (IGZO) oxide semiconductor, namely, C-axis aligned crystalline (CAAC)-IGZO. Displays using CAAC-IGZO are already being manufactured by companies such as Sharp. You can see my videos of Sharp IGZO displays here. CAAC-IGZO can be used not only in displays but also is CPUs and memories. If silicon LSI is replaced with IGZO LSI, the power consumption for processors may become less than 1%. Silicon used mainly at present will be replaced with CAAC-IGZO in the near future. In the coming AI age, it is indispensable to develop IGZO LSI. Dr. Yamazaki and the researchers of SEL are concentrating on R&D of IGZO LSI.

Posted by Charbax – June 2, 2018

BOE presents their latest flexible AMOLED display solutions for the future of smartphones that can be bent, folded, and rolled and even flap in the wind. BOE's flexible displays is demonstrated for robots with touch control, smart loudspeakers, an S-shaped in-car flexible AMOLED display. 8K displays, micro displays, QLED displays and other IoT solutions such as their TFT based AMOLED fingerprint recognition system that works in any spot of the display area

The foldable all-screen WQHD AMOLED display launched by BOE can achieve minimum dynamic bending with a radius of only 1mm. It can be bent more than 100,000 times and has an NTSC color gamut up to 118%. BOE is exhibiting a 5.99" FHD+ 2160x1080 Flexible AMOLED foldable mobile phone and a 7.56" foldable tablet. The display can be used for mobile phones when it is folded up and for tablets or monitors when it unfolds.

As one of the upcoming possibly revolutionizing OLED technical directions, BOE demonstrates their OLED printing technology to possibly just print the future of Smartphone displays showing their 5.5" FHD (1920×1080) printing flexible OLED display.

UHD has become a keyword of SID 2018 for material and equipment suppliers and device manufacturers, signaling the advent of the 8K era. In addition to the 110-inch 8K, 75-inch 8K, and 65-inch 8K glasses-free 3D displays, BOE also presents 13.3-inch 8K display products, promoting the development of small and medium-sized 8K products.

BOE has gathered speed in building an 8K ecosystem ever since it launched the "8425 strategy" which means "promoting 8K, popularizing 4K, replacing 2K and making good use of 5G". BOE has recently launched the 8K solution that incorporates BOE's 4K/8K image service cloud, 8K decoder player, and 8K display device, making it possible to shoot, edit, transmit and broadcast 8K content. This helps to solve problems like the costliness and massive size of traditional decoder players, as well as the lack of 8K content, thus promoting the faster popularization of 8K.

Among several micro displays at BOE's booth is a silicon-based OLED AR product which features monocrystalline silicon as the active drive backplane as well as high resolution, high level of integration, low power consumption, small size, and light weight. The AR product is backed by a 0.39-inch silicon-based OLED which has the world's leading pixel density of 5644PPI, 17 times that of a Retina display, and a contrast ratio over 10000:1, which enables the overlapping and interaction between virtual 3D images and real scenes. All these secure an ultimate experience for users as well as bright prospect in the field of education and training, video games, home decoration, etc.

Moreover, BOE shows its cutting-edge technologies and products such as QLED, mini-LED displays, a number of new applications and products including curved in-car display instruments and BOE iGallery.
