User Issues in 3D Stereoscopic Displays 
By Dr. Marty Banks of UC Berkeley 

 
This webinar covers a variety of user issues including:
  • The temporal protocols used in stereo 3D and how they affect perceived flicker, motion artifacts, and depth distortions
  • Head roll, vertical eye movements, and visual discomfort
  • Visual-vestibular conflict and nausea
  • Vergence-accommodation conflict 
  • Vergence: the inward or outward turning movement of the eyes in convergence or divergence
  • Accommodation: the focusing of the eyes to make the image on the retinas sharp.
  • Vergence and accommodation in natural viewing; coupling 
  • Vergence and accommodation in stereo displays
  • Optometric measures of discomfort 
  • Evidence that vergence-accommodation conflict with stereo displays causes discomfort: blurry vision, tired eyes, and headache 
  • The effect of the direction of the conflict (content in front of the screen or behind?) 
  • Maintaining comfort in different viewing situations 
  • Relating these findings to current practice
 


Oxide Electronics for Displays
By Prof. John F. Wager
Oregon State University
 
             

ABSTRACT
Amorphous oxide semiconductor (AOS) thin-film transistors (TFTs) are transitioning towards commercialization for active-matrix liquid crystal display flat-panel display backplane applications. They also appear to be well-positioned to meet the more demanding challenges associated with active-matrix organic light-emitting device backplanes. Additionally, AOS TFTs offer an attractive approach to printed electronics. The objectives of this talk are to (i) briefly review the origins and current status of AOS TFTs, (ii) offer a novel approach to their passivation, and (iii) consider possible future display applications.

ABSTRACT

In this talk, the basic concepts of 3D displays, especially for auto-stereoscopic 3D vision, will be discussed. Evidently, current approaches are not good enough for consumer electronics yet. Future technologies, therefore, such as 3D liquid crystal lens and 3-dimensional interactive/touch system, will be presented. By combining those developing technologies, it should be possible for flat panel 3D displays with naked eyes in the near future.


Liquid Crystal Photoalignment 
by Prof. V. Chigrinov
Hong Kong University of Science & Technology

 

  ABSTRACT
We will consider the novel azo-dye photo-aligning technology: including its perspectives for future applications in liquid crystal (LC) Displays and Photonics devices. Azo-dye materials can provide a perfect uniform alignment with a sufficiently high polar and azimuthal anchoring energy, VHR and appropriate pretilt angles. The stabilized azo-dye aligning layers are thermo and UV stable. Patterned LC alignment in LCP films and LC alignment in superthin tubes and 3D surface becomes possible. Photoalignment applications in displays, Photonics and Optics become a “hot topic” of research. Latest tendencies of photoalignment technology applications in displays will be also considered.


Recent developments of Oxide TFT and some novel applications 
By Mr. Jun Koyama
Semiconductor Energy Laboratory Co. Ltd.
  




ABSTRACT
In 1985, Kimizuka et al. began research on crystalline IGZO. Subsequently, applications of amorphous IGZO to displays have been researched since about 2005. We discovered CAAC (c-axis aligned crystal) and has investigated applications of CAAC to displays, memories, etc. We will show you applications of our crystalline IGZO, specifically a LCD consuming less power due to longer retention time, a flexible OLED display, a memory device and a image sensor.



Merging Liquid Crystals and Microstructures
by Prof. Yan-qing Lu

 

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.

SID Display Week 2012 Summary by Alfred Poor


Abstract:
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.

 


How LCD’s could get their groove back  
by 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.

 
The PC Display's Next Big Hurdle: Better Color
by 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.

 
Touchless Gestures Go Mainstream
by Dr. Francis MacDougall
Qualcomm 
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.
Medical Display Optimization: Measuring the human perception of factors like non-uniformity and limited response time
by Albert Xthona  
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.

Quantum Dots LEDs for Lighting and Backlight applications
Juanita Kurtin

  ABSTRACT:
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

  ABSTRACT:
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.

Goh Itoh
  ABSTRACT:
We have developed several technologies for glass-free 3D displays to produce a clear 3D image and offer an attractive application. Hardware technologies such as one-dimensional integral imaging method, a new moire-free pixel design using a vertical lenticular sheet, and 2D/3D switching with liquid-crystal gradient index (LC GRIN) lens are useful for 3D panels. Software technologies such as 2D3D image conversion, face tracking for 3D viewing zone shift, and 3D super-resolution image processing are for enjoying 3D movies. We continue to invent a 3D new technology especially for mobile devices and for business use.

From Backlight to Luminaire
T. Dekker, T. Bergman, G. Vissenberg
  ABSTRACT:
As display and lighting technologies are growing closer together, concepts from both worlds can be used to accelerate future innovation. In this paper we present a novel office luminaire concept which uses only proven technologies known from the backlight industry. The new luminaire is semi-transparent and creates a glare free beam of light. Moreover, it enables a single luminaire with a dual beam character i.e, task lighting downwards and indirect general lighting upwards.
