Atwood Technologies 617/306-9729, [email protected] Editor in Chief: Jenny Donelan by Stephen P. Atwood 603/924-9628, [email protected] Welcome to the final issue for 2018, and one that is Global Ad Director: especially forward-looking, as you can see from our cover. Dan Nicholas, [email protected] Throughout the year, we have heard a lot of discussion about Senior Account Manager emissive materials and their potential. They were a major Print & E-Advertising: theme at Display Week 2018, and they are clearly supported Roland Espinosa by a great deal of R&D spending around the world. 201/748-6819, [email protected] Emissive technologies, organic and inorganic, in various forms, have been around since the birth of information displays. CRTs used phosphors, which are inorganic Editorial Advisory Board emissive compounds that often utilized rare-earth metals, to make their images. Plasma Stephen P. Atwood, Chair displays also used phosphors, and there have been many other examples, such as Azonix Corp. vacuum-fluorescent and thin-film electroluminescent displays. Many of these displays Ioannis ( John) Kymissis Electrical Engineering Department, Columbia worked in certain applications, but for various reasons lacked the ability to scale in University terms of size (larger or smaller), resolution, optical performance, or other aspects that Larry Weber limited their commercial life. And yes, I know it’s rather glib to write off 100 years of Consultant CRT technology as having “limited” commercial life. But as we know today, there are a multitude of product embodiments such as tablets, smartphones, and large-screen Guest Editors TVs that were never going to be achieved with CRTs. Hence the generational hunger Lighting in our industry for something more – the same hunger that continues to drive Marina Kondakova, OLEDWorks researchers toward even better solutions today. As you will learn in this issue, many AR/VR hope to find those solutions through entirely new classes of emissive technologies. Seth Coe-Sullivan, Luminit Automotive Displays One-Day Conference from the LA Chapter Karlheinz Blankenbach, Pforzheim University However, before we dive into the emissive articles for this issue, I want to draw your Digital Signage attention to the terrific upcoming program on “Selecting and Customizing Gary Feather, NanoLumens Display Products” being hosted by the Los Angeles Chapter of the Society for Emissive Technology Information Display on February 8, 2019. I’m told this is the chapter’s 15th year Ruiqing (Ray) Ma, Nanosys organizing this annual program, which proves time and again to be one of the most useful and practical technical seminars in SID’s regional portfolio. I have attended Contributing Editors several of these programs in the past, including ones on advanced television, LCD Steve Sechrist, Consultant modules, and LEDs. I referred to the notes from the 2008 LED conference many, Paul Semenza, Consultant many times while designing ruggedized backlights over the years that followed. Raymond M. Soneira, DisplayMate Technologies The organizing team in LA includes many well-known industry veterans, including this year’s conference chair Larry Iboshi. The speaker lineup looks to be stellar as well. In our SID News department you can read more about the details of the event. And let’s be honest: what’s not to like about a trip to LA in early February, especially to spend a day at the Costa Mesa Country Club? Emissive Progress Our guest editor for this issue is Ruiqing (Ray) Ma, who is currently working as the director for QD devices at Nanosys. Ray has served both as a guest editor and contributing author for ID many times and continues to be one of our go-to experts for emissive technology. In his guest editorial for this issue, Ray expresses renewed excitement about the prospects for emissive technology to help define the future of The opinions expressed in editorials, columns, and displays. Whether through the further merging of quantum dots (QDs) and LCDs or feature articles do not necessarily reflect the opinions of through completely new emissive display architectures, the options are becoming the executive editor or publisher of Information Display more viable for breakthrough product designs. Thanks to Ray for all his hard work in magazine, nor do they necessarily reflect the position of the Society for Information Display. developing our technical lineup for this month.
