Sendai College of Japan shows micro-optical diffused light-control film (DLC)

Posted by Charbax – June 17, 2018

Researchers at the Optical Function Device Workshop at the National Institute of Technology, Sendai College, demonstrated unique screens using micro-optical elements for projection displays. The screen is a combination of directional diffused light-control film (DLC) with a micro-structured optical film. The screen directs the environment-scattered light to a direction that is different from that of the screen viewer. One is a directive screen using an array of CCR with diverted and curved surfaces (D-CCR), which reflects and scatters the light toward a certain angle: the viewer’s face. The screen has a gain of 16 and reflects extremely bright images even with small and low-power projections.

Best of I-Zone 2018: FLC Display without Color Filter by Hong Kong University

Posted by Charbax – June 14, 2018

The Best Prototype at I-Zone 2018 award winner at SID Display Week 2018 is Hong Kong University of Science and Technology. They present a solution to lower the power consumption of LCD by 3x by removing the color filter, their 250ppi active-matrix field-sequential color-display panel based on electrically suppressed helix ferroelectric liquid crystal (FLC). FLC's fast response time of 10 microseconds under low voltage of 6.67V/micron enables field sequential color display operation with a 60-Hz frame rate and 360-Hz FLC driving frequency.

Reflective Electrowetting Display by South China Normal University at SID Display Week 2018 I-Zone

Posted by Charbax – June 14, 2018

South China Normal University (SCNU) has been developing reflective displays based on the “electrowetting” effect since 2012. A key point in their technology is the improvement of the aperture of display pixels, which for typical electrowetting displays is approximately 70 percent. SCNU displays include apertures of 85 percent, and if these cells are used in stacked cyan, magenta and yellow cells, the displayed colors are markedly more bright and saturated than in 70 percent aperture cells. As part of this key development, the contrast ratio must be maintained or increased, which is achieved by minimizing the stray light transmitted. Contrast ratios up to 20:1 can be shown.

PlayNitride MicroLED Wins Honorable Mention Award at Display Week 2018 I-Zone

Posted by Charbax – June 14, 2018

Taiwan’s PlayNitride, Inc. received an honorable mention for utilizing its PixeLED display technology to build a transparent display with an innovative and unique process to transfer RGB microLEDs onto a pixel.

During Display Week 2018, PlayNitride demonstrated two microLED prototypes. One is a small 0.89" 64x64 (105 PPI) panel with a brightness of 800 nits. All of the LED chips in this display were transferred in three shots (one shot per color). The pixel size in this display is 0.243 mm.

The second display is a larger panel - 3.12" 256x256 (116 PPI). Due to the larger number of LEDs (total of 786K LEDs) PlayNitride had to use 24 shots to transfer all three colored chips. The pixel size in this larger display is 0.219 mm.

Quantum Solutions Quantum Dots at Display Week 2018 I-Zone

Posted by Charbax – June 14, 2018

Quantum Solutions is a start-up based in Saudi Arabia, focused on nanotechnology, developing and manufacturing Quantum Dots (QDs) for optoelectronic applications: LCD displays, LEDs, solar cells and photo detectors.

At the I-Zone, they demonstrated their high-efficiency green for LCD applications that replaces the current LCD white with quantum dots using a special film, which ensures a wider color gamete. What makes their technology unique is its 15-nanometer emission for quantum dots. According to Quantum Solutions, current market efficiency is high but the emission width is broad at 30-40 nanometers. Quantum Solutions’ product is much narrower at 15 nanometers, which provides a wider color gamete that can produce an exact green to mix with other RGB colors to create more vibrant and accurate color combinations.

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.

Vuzix Blade Developer Kit AR Smart Glasses about to ship

Posted by Charbax – June 11, 2018

Paul Travers, President and CEO at Vuzix talks about how Vuzix is about to ship the Vuzix Blade Developer Kit to developers, providing a wearable smart display with a see-through viewing experience utilizing Vuzix's proprietary waveguide optics and Cobra II display engine, to be able to see overlaid information, indoors or out, such as patient data, mapping directions, restaurant menus, weather information, alerts and more without picking up a smartphone. Vuzix Blade (see my previous videos about the Vuzix Blade here) can also synchronize and interact with a smartphone, allowing users to keep their phone in their pockets for almost everything where fashion meets technology in the wearable display arena. Vuzix also recently announced partnership to use the new Qualcomm Snapdragon XR1 Platform and also working with Plessey microLED Microdisplay Technology.
