Overcoming Challenges in LED Technology for Signage Applications  

Robert Young

SiliconCore Technology

Oct 14th, 2015


The market for signage displays, particularly the indoor signage segment is growing rapidly. Current LED technology has neither the resolution nor the cost structure to support consumer applications. The speaker will discuss the current challenges with LED displays that has limited its use to commercial applications and propose improved technologies that are enabling the use of LED displays in consumer applications. These new technologies also enable higher brightness, more uniform, lower power LED displays apart from the higher resolution. The talk will cite examples of high resolution LED technology for indoor consumer applications such as Broadcast/TV studios, Retail Signage, Control Room and Military, Museums and indoor sports venues.

Interacting with 3D Displays  
Dr. John M. Wyrwas

Dr. Hae Jong Seo

Jul 27th, 2015

A novel three dimensional user interface technology (3D UI) is demonstrated.The interface is a single planar device enabling multiple modes of human/machine interaction operating continuously from on the device surface to off the device surface; a surface-to-air capability.For example, our device can not only sense multiple finger touch and multiple stylus interaction on its surface, but also can detect “air touch”, “air pinch” and gestures in the near field space up to several inches above its surface.Thus, two dimensional user interface functionality has been extended continuously into the third dimension above the device.

Light Field Imaging and Display – A System Perspective 
Dr. Nikhil Baram
Ricoh Innovation Corp
Jul 15th, 2015


Light fields provide a natural way of representing information that is captured and processed by the human visual system. Recently it has become possible to capture light fields using compact imaging systems and use the 3D information for useful purposes. Displaying information using light fields has also become possible, enabling true 3D displays that provide a natural and comfortable experience. But there are significant design choices that need to be made for different types of applications. In both cases – light field imaging and light field display – the overall system has to be designed considering a complex set of tradeoffs, some of which are still not fully understood. This seminar will provide a brief introduction to light fields, followed by an overview of state-of-the-art light field imaging and display systems and some promising early applications and discuss key tradeoffs that have to be considered for compact mobile systems. Demo videos will be shown in lieu of live demos.

Making Computer Vision Work for Humans 
Dr. Nikhil Baram
Ricoh Innovation Corp
May 20th,2015




Image recognition using feature matching has existed for well over a decade. But it has not seen large scale mainstream use because of the gap between what different variants of the technology can deliver versus the kind of natural usage people have in mind for their personal or business tasks. Bridging that gap has required the use of the Deep Innovation model to produce computer vision solutions that can be used by ordinary people to enhance their work and lives. This seminar will provide an overview of the state of the art in these techniques and illustrate, with demonstrations, how these are being implemented into useful and natural solutions. It will also provide a vision of the future.

Dennis Kucera
Oct 1st, 2014

With 4k video becoming more common, what methods are being used to deliver this new video to the users at home? What are the issue and challenges? MPEG-2 video definitions from 1994 to today limit both frame rate and horizontal resolution of video. So we will look at newer standards available today to deliver 4k video to the home. Recent examples include the Olympics at Sochi, World Cup soccer games in Brazil, as well as Netflix.
Quantum Dots LEDs for Lighting and Backlight applications
Juanita Kurtin
May 1st, 2014

Quantum dots (QDs) are finally delivering on the promise of bringing wide color gamut and high efficiency to displays in consumer electronic devices with their recent advent in several display products. For the first time, low-cost LCD displays can expand the color gamut well beyond the sRGB standard to rival the more costly and power-hungry OLED display. This is made possible by the narrow emission spectra of the QD emitters that result in the dual benefits of moving the primaries closer to the edges of the monochromatic locus of the color chart while reducing light leakage through adjacent filters, in combination with the ability to choose any desired emission wavelength. However to date QDs have only been successful as an off-chip optical element rather than as on on-chip replacement for phosphors, which increases the expense and decreases the flexibility of a QD solution for displays. This is due to the temperature, radiant flux, and environmental demands of the on-chip architecture that in the past have exceeded the capabilities of quantum dot materials. Pacific Light Technologies (PLT) has now developed a patented nanomaterial design that for the first time makes on-chip applications accessible by quantum dots, thereby bringing the benefits of spectral control, high-efficiency, and high color-rendering that quantum dots enable to a much larger market. This talk will present our recent progress in on-chip application and testing of quantum dot downconverters, covering materials that emit in the range from green to red wavelengths.

CAAC Oxide Semiconductor and its Application: Flexible AM-OLED
Prof. Yoshitaka Yamamoto
Semiconductor Energy Laboratory Co. Ltd

Flexible AM-OLED is one of the most attractive technologies for next-generation display applications. We have been developing flexible displays such as curved or foldable displays by using a technology of CAAC-OS (oxide semiconductor). CAAC-OS, which we have developed in research of OS, is the suitable material for practical use; a CAAC-OS FET shows high device performance, reliability, and productivity. To realize the flexible OLE display, we have combined the technologies of CAAC-OS FET, transfer, and white OLED using a color filter, and achieved fabricating a 5.9-inch foldable display, a 13.5-inch 4K display, and a 13.3-inch 8K display.

Medical Display Optimization: Measuring the Human Perception of Factors like Non-uniformity and Limited Response Time
Albert Xthona of Barco
January 9, 2013
Albert Xthona of Barco
Abstract: Creating medical displays requires addressing many display factors. Indeed many are common to all displays: luminance, viewing angle, etc. However, for medical displays, the question of which factors are most clinically important informs design tradeoffs. This talk discusses the measurement of the clinical impact of these performance factors. Focus will be on the relevance/irrelevance of various factors and on the measurement of the impact of response time, spatial noise, and luminance.

Touchless Gestures Go Mainstream
Dr. Francis MacDougall
November 14, 2012

Abstract: Touch-free gestures are moving from the world of Xbox 360 Kinect games into mainstream devices including mobile phones, tablets, laptops, digital cameras and TVs. This talk reviews recently released products that incorporate gesture control and contrasts the various implementations of gesture control in each product. These initial products are starting to define a “gesture vocabulary” that could allow touch-free gestures to be ubiquitous across a wide range of devices. However, there is a danger of having conflicting gesture implementations on different devices that could cause consumer confusion and constrain the potential market. The talk also discusses the various technologies for detecting gestures as well as the leading use-cases, power-consumption issues, and complementary technologies that typify the next-generation user-interfaces enabled by gestures.

The PC Display's Next Big Hurdle: Better Color
Scott Anderson
VP Product Management
Portrait Displays
October 24, 2012




Abstract: For over a decade, PC displays have been marketed by advances in resolution, viewing angle, brightness and size, but never by the quality of the colors they present. Now PC displays have to step up to the plate and address this new objective. Color variations can easily be seen when viewing content on different devices such as desktops, laptops, and tablets. With so much emphasis being placed on the display's performance, color accuracy is paramount in viewing content correctly, regardless of the device. Manipulating color gamut and gamma is a way of achieving more consistent color across different platforms for a better viewing experience, as well as a way of producing industry- standard color spaces. With proper control, the colors of any display (regardless of gamut) can be altered to remove cast, improve color balance, and provide subjective or objective color accuracy. Gamut and gamma control can be applied to narrow-gamut, standard-gamut, and wide-gamut panels. Wide-gamut produces rich vibrant colors but lacks control to accurately show content that was created using color standards such, as sRGB or AdobeRGB. Standard-gamut 72% panels should be sRGB compliant, but tend to drift from the actual specification, resulting in inaccurate web images. Narrow-gamut panels, 60% and 45% of NTSC, commonly found on laptops, tend to have color-cast problems. All these platforms can benefit from consistent color control.

How LCD’s Could Get their Groove Back  
Dr. Mary Lou Jepsen
CEO & Founder, Pixel Qi 
September 19, 2012

For a few years now LCDs have been sold for about 80% of what they cost to make, due to a growing capacity glut. Despite this glut, China says they are increasing worldwide capacity by another 15% this year. But this is not all gloom and doom… it’s actually terrific news for those of us who want to use that excess capacity to create innovative displays that can ship in high volume to transform what people can do with computing. Anticipating this situation, in 2005 I began to emulate the CMOS silicon ASIC industry and create innovative display architectures that could be fabricated in the existing LCD manufacturing facilities to allow rapid innovation to reach high volume mass production. 8 years later I’m working with a virtuoso team of top display architects in a startup creating highly innovative screens that ship rapidly and in volume from the world’s largest fabs. That was our warm up act. I’ll talk about the road we have traveled, what we are doing now at Pixel Qi, and what we think this spells for the future of devices at this exhilarating moment.

Merging Liquid Crystals and Microstructures
Prof. Yan-qing Lu
  Aug 2nd, 2012



Inducing micro-patterns and structures inside a Liquid crystal (LC) cell is an effective way to improve the performance of LC display, for example, widening the view angle. However, in addition to display applications, LC also plays an important role in various tunable photonic devices with the advantages of low cost, no moving parts, low power consumption and high reliability. In this talk, I am going to review some of our work in merging LC and various artificial microstructures in different spans. The related applications are discussed.

When the typical size of a LC microstructure is much larger than the light’s wavelength, it would just work like a multi-pixel LC modulator that is very useful in fiber-optic devices to process multi-channel DWDM signals simultaneously. We design and developed a LC based 40 channel 100GHz spacing wavelength blocker that could regulate the light powers of arbitrary channels.

If the LC microstructure is in the micrometer span, which is comparable with the light’s wavelength, the diffraction effect thus should be taken into account. As the simplest case of LC diffractive element, LC grating has been widely studied. We developed a serial of LC tunable 1D/2D gratings based on the photo alignment technique with both PA/PA and PA/TN configurations. In addition, ferroelectric LC and blue phase LC gratings are also demonstrated. To realize arbitrary LC alignment microstructures, we further propose and implement a DMD based dynamic micro-lithography system thus could instantly write complicated patterns in the LC cell. Besides normal phase gratings, more complex patterns such as quasicrystal and chequerboard structures are demonstrated. Compared to other techniques, our method enables the arbitrary and instant manipulation of LC alignments and light polarization states, facilitating wide applications in display and photonic fields.

Alfred Poor
Jul 18th,2012


SID Senior Member and Information Display Contributing Editor Alfred Poor summarizes Display Week 2012, covering many of the highlights from the Exhibit Hall to the Symposium. Alfred's talk includes a discussion of some of the Display of the Year and Best of Show award winners. You'll even hear about some of the intriguing new technologies that were on display at Display Week's new and wildly popular "Innovation Zone," the I-Zone. The talk also covers important trends, such as the move from aSi and LTPS backplanes to the use of metal oxides such as IGZO. The newer technology offers electron mobility between the two other solutions, with the advantage that it may scale better than p-Si for very large screens, although some challenges remain. Hear about other advances, ranging from touch-screen technology to thin-substrate glass that can support roll-to-roll continuous processing. SID Display Week 2012 was filled with energy and information, and this seminar is as well.

A Novel Triplet Green Host System and Charge Balance Tuning for High-Performance Singlet Blue Devices
Christof Pflumm

Our former findings on the charge balance in blue fluorescent devices show a clear connection between the basic performance parameters: Efficiency and lifetime both show an optimum with respect to voltage. Unfortunately, for devices using a conventional hole injection and NPB as hole transport materials, the optimum values do not occur at the same voltage. Moreover, the optimum voltage for lifetime is much higher than that for optimum efficiency. After investigating the underlying charge balance issue, we developed new stack layouts and hole transport materials to shift the lifetime optimum to lower voltage values. Using and appropriate hole injection layer and one of our latest hole transport materials. We can now combine excellent lifetime, low voltage and good efficiency in one fluorescent blue device. In addition, we obtain 10% EQE by carefully tuning the hole transport side in fluorescent blue devices. No special hole blocking layer is required to obtain this high efficiency. For green phosphorescent devices, we developed thermally stable co-host materials which allows for the use of low emitter concentrations in the range of 5% without sacrificing device performance. We combine this material with an electron transporting host that shows a slight initial rise in lifetime when a lower emitter concentration is employed. Due to these features, the tuning of the host mixing ratio results in excellent LT95 values in combination with good voltage, efficiency and low efficiency roll-off for high luminance.
