REVIEW OF PAPER-LIKE DISPLAY TECHNOLOGIES (Invited Review)

Abstract

Abstract-With the advancement of wireless networks and cloud computing, people are becoming increasingly surrounded by a variety of displays -rich electronic devices: TV, Phone, Pad, Notebook and other portable or wearable devices. These electronic products put high demands on the quality of the visual interface. Paper-like displays are reflective and do not require a backlight. They have received much attention after electrophoretic-based electronic paper displays were commercialized in 2004. Paper-like displays combine excellent reading experience with ultra-low power consumption. In particular, their outdoor readability is superior to transmissive liquid crystal displays (LCDs) and organic light emitting devices (OLEDs). In this paper, we give an overview on various paper-like display technologies with emphasis of the status and future development of electrophoretic display and electrofluidic display principles. We focus on both technologies because electrophoretic displays have been commercialized successfully, and electrofluidic display has high potential to deliver video and full color.

Bistable and Reconfigurable Photonic Crystals—Electroactive Shape Memory Polymer Nanocomposite for Ink‐Free Rewritable Paper

“…Recent attempts to create and popularize rewritable paper can greatly lessen the heavy environmental burden brought about by traditional pulp and paper industry . Currently, paper‐replacement effort is developing around several distinct technologies: electrophoretic inks, electrowetting inks, cholesteric liquid crystals, reprintable coatings on paper, and responsive photonic crystals . Microencapsulated electrophoretic display was first introduced by an MIT group in 1998, which quickly enabled the commercially successful, monochromic e‐readers popular for their low power consumption due to its bistability and paper‐like legibility under illumination.…”

“…Current proposals either suffer from significant reflected light intensity loss due to color filters or require complex manufacturing processes to create subpixels with different colors and convoluted charging system . Electrowetting displays are another commercialized electronic paper that was invented by Liquavista in 2003 . They were capable of frame rates suitable for video play with their fast switching speed through applied voltages .…”

Direct Assembly of Magnetic Janus Particles at a Droplet Interface

“…Therefore, the estimated response time is around (µa/γ 12 ) × 3 × 10 3 ≈ 4 × 10 −7 s ≈ 400ns, which is fast enough to satisfy the requirements of responsive materials for advanced sensor or display technology. 24 For a possible experimental relization of our system, we note that surface nanodroplets can be produced through a solvent exchange process in experiments. 25,26 Multiple magnetic Janus particles.…”

P‐139: High Optical Contrast Reflective Display with Electrochromism

“…Considering these requirements, reflective display is more suitable than emissive display for this application. Emissive displays have normally low contrast ratio and high power consumption under the strong ambient light condition due to their driving mechanism of current based light generation [1][2].…”
