    There is currently significant interest in 3D fabrication in middle school classrooms. At its best 3D printing can be utilized in authentic design projects that integrate math, science, and technology, which facilitate deep learning by students. In essence, students are able to tinker in a virtual world using 3D design software and then tinker in the real world using printed parts. We describe a professional development activity we designed to enable middle school teachers who had taken part in a three-year Math Science Partnership program to authentically integrate 3D printing into design-based lessons. We include some examples of successful design-based lesson plans

    Flexible Flat Panel Displays A complete treatment of the entire lifecycle of flexible flat panel displays, from raw material selection to commercialization In the newly revised Second Edition of Flexible Flat Panel Displays, a distinguished team of researchers delivers a completely restructured and comprehensive treatment of the field of flexible flat panel displays. With material covering the end-to-end process that includes commercial and technical aspects of the technology, the editors have included contributions that introduce the business, marketing, entrepreneurship, and intellectual property content relevant to flexible flat panel displays. This edited volume contains a brand-new section on case studies using the Harvard Business School format that discusses current and emerging markets in flexible displays, such as an examination of the use of electronic ink and QD Vision in commercial devices. From raw material selection to device prototyping, manufacturing, and commercialization, each stage of the flexible display business is discussed in this insightful new edition. The book also includes: Thorough introductions to engineered films for display technology and liquid crystal optical coatings for flexible displays Comprehensive explorations of organic TFT foils, metallic nanowires, adhesives, and self-healing polymer substrates Practical discussions of flexible glass, AMOLEDs, cholesteric displays, and electronic paper In-depth examinations of the encapsulation of flexible displays, flexible batteries, flexible flat panel photodetectors, and flexible touch screens Perfect for professionals working in the field of display technology with backgrounds in science and engineering, Flexible Flat Panel Displays is also an indispensable resource for professionals with marketing, sales, and technology backgrounds, as well as senior undergraduates and graduate students in engineering and materials science.</p

    "Since the early 2000's there has been an explosion in interest in printed electronics and flexible displays both in terms of exploring the potential to develop new business opportunities and also in terms of developing the technology base. The opportunity to exploit flexible substrates in R2R production has been one that has excited the interest of the plastic films and associated processing and coating industries. To replace a rigid substrate such as glass however, a plastic substrate needs to be able to offer some or all of the properties of glass ie clarity, dimensional stability, thermal stability, barrier, solvent resistance, low coefficient of thermal expansion (CLTE) coupled with a smooth surface. In addition a further functionality such as a conductive layer might be required. No plastic film offers all these properties so any plastic based substrate replacing glass will almost certainly be a multilayer composite structure1,2,3. Not all applications however require such a demanding property set and over the past decade plastic films have found application in areas broader than the flexible OLED displays initially envisaged in the early days of the technology development. These include applications such as electrophoretic displays driven by TFT arrays printed on plastic film, printed memory and sensors. In addition there has been a smearing of the boundary between flexible devices and the use of printed electronics and or flexible substrates in rigid devices an example being the use of conductive films in touchscreens incorporated into smart phones and tablets."--Includes bibliographical references and index."Since the early 2000's there has been an explosion in interest in printed electronics and flexible displays both in terms of exploring the potential to develop new business opportunities and also in terms of developing the technology base.
