Upcoming Webinar: May 15-16^th, 2012: Auto-stereoscopic 3D Displays

Click here to view bio		By Prof. Yi-Pai Huang, Ph.D National Chiao Tung University, Hsinchu, Taiwan 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.

Upcoming Webinar: Liquid Crystal Photoalignment, May 28/29
Prof. V. Chigrinov		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. The advantages of LC photoalignment technology in comparison with common “rubbing” alignment methods tend to the continuation of the research in this field. Almost all the criteria of perfect LC alignment are met in case of azo-dye layers. Nowadays azo-dye alignment materials can be already used in LCD manufacturing, e.g. for the alignment of monomers in LCP films for new generations of Photonics and Optics devices such as phase retarders, polarizers and color filters. We will have a possibility to tune the alignment properties like (anchoring energy, ability of align LC materials, image sticking, light sensitivity, photo stability, reorientation speed etc.) by preparing the proper weight ratio of the azo-dye compound. Thus having the limited number of basic azo-dyes structures the continuous range of different alignment properties can be covered. Recently the new application of photoaligned technology for the tunable LC lenses with a variable focal distance was proposed. Thin photo-patterned micropolarizer array for CMOS image sensors for in-situ analysis of the four Stokes parameters of the output optical signal are also envisaged. Photoalignment is definitely the only technology, which enable non-defect LC orientation inside superthin tubes (tunable photonic crystal/liquid crystal fiber structure) and on tiny rings (Si micro-ring resonators). New optically rewritable (ORW) liquid crystal Photonics devices with a light controllable structure may include LC plane waveguides, LC polarization dependent elements, such as lenses and wave plates, LC polarization rotators and polarization controllers, light and voltage controllable diffraction gratings for optical filters etc. We are sure, that the common rubbing alignment technology will be totally replaced by a photoalignment in the near future, thus increasing the quality of LCD (http://sharp-world.com/corporate/news/090916.html).

Upcoming Webinar: Recent developments of oxide TFT and some novel applications, June 26/27
Bio		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.

Webinar archive: Oxide Electronics for Displays

By Prof. John F. Wager, Ph.D School of EECS, 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.
