In order to develop products using these forms of flexible displays, designers have to consider all of their practical limitations which includes the rigidity of elec- contents tronic components. These limitations are unique 2 Editorial: The First Days of Spring to eachDISPLAY specific WEEK 2016 application.PREVIEW AND FLEXIBLE AsTECHNOLOGY a result, for each n By Stephen P.

An essen- tial component of this capability is flexible TFT technology, which requires a materials set specifically designed to perform optimally under mechanical stress.

It started with 603/924-9628, [email protected] CES in January, when we saw a significant number of new Global Advertising Director: display achievements and continues through May, when we Stephen Jezzard, [email protected] all come together for the annual Display Week gathering – the largest and most complete convergence of display- Senior Account Manager Print & E Advertising: industry activities in the world. In between these two, Roland Espinosa we see many local and regional events (such as the China Display Conference and the 201-748-6819, [email protected] Electronic Displays Conference in Germany), all warming us up for Display Week.

Helge Seetzen We will talk more about Display Week shortly, but first let me discuss our technical TandemLaunch Technologies, Westmont, Quebec, focus for this issue, which is flexible displays – an area of R&D that is bringing a lot Canada of promising new capabilities to the marketplace. We have already seen curved and Allan Kmetz flexible displays in numerous consumer products – generally packaged as rigid or Consultant, U.S.A. mildly flexible solutions such as a phone that will not break if you put it in your back Larry Weber Consultant, U.S.A. pocket and sit on it. We have also seen a myriad of curved LCD (and a few OLED) TV-size screens shown and sold commercially. So, the concept is becoming more Guest Editors main stream, but a display that you can literally roll up or fold up still eludes us. Applied Vision Thanks to important product segments such as wearables and tablet computers, Martin Banks, University of California at Berkeley there is no shortage of commercial interest in the ultimate flexible-display solution. Automotive Displays We start off this month with three excellent Frontline Technology articles that Karlheinz Blankenbach, Pforzheim University address critical building blocks toward achieving true flexibility, for which we thank Digital Signage our terrific guest editor Ruiqing (Ray) Ma from Universal Display Corp. I recom- Gary Feather, NanoLumens mend that you start by reading Ray’s guest editorial titled “Flexible Displays Come in Display Materials Many Forms” to get his perspective on the context for these three key articles. Then John F. Wager, Oregon State University jump right in to enjoy “Enabling Wearable and Other Novel Applications through Emissive Displays Flexible TFTs” by Antonio Facchetti and his colleagues at Polyera, whose work in Qun (Frank) Yan, Sichuan COC Display Devices organic electronics has yielded organic TFT backplanes capable of near-endless Co., Ltd. bending. Their concept product, the “Wove Band,” is literally a wearable rectangular Flexible Technology wristband with an electrophoretic display and touch screen along the entire length.
