Two-phase microfluidic flow modeling in an electrowetting display microwell

The European Physical Journal E, 2016
Digital microfluidics provides precise control of a single microdroplet, producing more opportunities for bio-molecule studies, chemical reaction and optofluidics applications. By manipulating the surface of droplets, light can be focused, scattered, or reflected toward different positions.

Electrowetting-Based Displays: Bringing Microfluidics Alive On-Screen

19th IEEE International Conference on Micro Electro Mechanical Systems, 2006
We present the use of electrowetting as a technology for very bright and energy-efficient displays. The intrinsic nature of the system as an optical switch provides an excellent starting point upon which a wide variety of display configurations can be based.

53.2: Recent Improvements of Droplet‐Driven Electrowetting Displays

SID Symposium Digest of Technical Papers, 2008
Abstract A new display technology based on droplet moving by electro‐wetting was introduced in 2007. Major improvements were made regarding hydrophobic layer, fluids, pixel layout, driving electronics and system design resulting in an operating voltage of less than 20 V for a 2 mm droplet.

Three-color electrowetting display device for electronic paper

Applied Physics Letters, 2010
Three-color electrowetting (EW) reflective display devices have been achieved using a vertical stack structure with colored oils. Fundamental properties (interface tension and geometry) of the EW process were investigated. Arrays of ∼1000–2000 pixels were constructed with pixel sizes of 200×600 and 300×900 μm2.

Lightweight electrowetting display on ultra‐thin glass substrate

Journal of the Society for Information Display, 2013
AbstractMobile display devices that use ultra‐thin (≤100 µm) glass substrates offer a combination of attractive characteristics: lightweight, high quality device fabrication process, thermal and dimensional stability, and mechanical flexibility. Electrowetting (EW) devices fabricated on ultra‐thin glass are demonstrated in this paper.

62.3: Production Considerations for Bistable Droplet Driven Electrowetting Displays

SID Symposium Digest of Technical Papers, 2012
Abstract The electrowetting displays are widely discussed within the last years. A colored liquid is deformed or moved from a visible to a non‐visible position. The production aspects of such microfluidic structures has to cover microfluidic channel structures, filling procedures, sealing, temperature stability and ‐ electrodes for ...

Open-structure electrowetting display with capacitive sensing feedback system

2015 28th IEEE International Conference on Micro Electro Mechanical Systems (MEMS), 2015
We report an open-structure electrowetting-based reflective display with capacitive sensing feedback that enables an effective self-dosing of ink, high contrast, and the precise control of color level. EWOD-based reflective display [1, 2] has been considered as a promising display technology due to high speed and contrast for e-paper application, but ...

51.4: Development of Flexible Electrowetting Displays for Stacked Color

SID Symposium Digest of Technical Papers, 2009
Abstract Electrowetting displays show promise for realizing vividly colorful electronic paper using stacked color layers to obtain high reflectivity. We develop and demonstrate technologies needed to realize stacked displays including (1) strategies for controlling colorant location, (2) incorporating spacers, black surround, and thin
