Title: Quantitative Analysis of Color Differences within High Contrast, Low Power Reversible Electrophoretic Displays

Abstract

Here, quantitative color analysis is performed on videos of high contrast, low power reversible electrophoretic deposition (EPD)-based displays operated under different applied voltages. This analysis is coded in an open-source software, relies on a color differentiation metric, ΔE^*₀₀, derived from digital video, and provides an intuitive relationship between the operating conditions of the devices and their performance. Time-dependent ΔE^*₀₀ color analysis reveals color relaxation behavior, recoverability for different voltage sequences, and operating conditions that can lead to optimal performance.

Correlating dynamic microstructure to observed color in electrophoretic displays via in situ small-angle x-ray scattering

Journal Article Bukosky, Scott C. ; Hammons, Joshua A. ; Giera, Brian ; ... - Physical Review Materials

Electrophoretic deposition (EPD) is an industrially relevant and scalable technique used to form particle deposits from colloidal suspensions. Highly concentrated particle suspensions generally prevent real-time in situ microscopy observations which limit the characterization of EPD films to ex situ, or postprocessed, laboratory techniques. For dynamic systems, such as tunable amorphous photonic crystals (APCs), only reversible deposits are formed during the EPD process. Since reversible deposits cannot be characterized with standard ex situ methods, the particle-particle and particle-field interactions that govern the displayed color and crystallinity of these systems are not well understood. In this paper, we present in situ small-anglemore »« less

Electrophoretic deposition of Y{sub 2}O{sub 3}-stabilized ZrO{sub 2} electrolyte films in solid oxide fuel cells

Journal Article Ishihara, Tatsumi ; Sato, Keiji ; Takita, Yusaku - Journal of the American Ceramic Society

An electrophoretic deposition (EPD) method was applied for the preparation of yttria-stabilized zirconia (YSZ) films for solid oxide fuel cell (SOFC) applications. Dense YSZ films with uniform thickness can be readily prepared with the EPD method by using acetylacetone or acetone as a solvent. The open-circuit voltages of SOFC, for which the YSZ films were prepared by the EPD method, increased with increasing repetitions of deposition and sintering. It was found that the open-circuit voltage exceeded 1.0 V after five repetitions. When the planar SOFC was fabricated using La{sub 0.6}Sr{sub 0.4}MnO{sub 3} as a cathode, and electroless plating Pt asmore »« less

Electrophoretic deposition of Y{sub 2}O{sub 3}-stabilized ZrO{sub 2} on the porous La{sub 0.8}Sr{sub 0.2}MnO{sub 3} cathode substrate for SOFC

Book Ishihara, Tatsumi ; Shimose, Kuninobu ; Takita, Yusaku ; ...

Preparation of YSZ film on La{sub 0.8}Sr{sub 0.2}MnO{sub 3} porous substrate was investigated using electrophoretic deposition (EPD) method. Since the electrical conductivity of La{sub 0.8}Sr{sub 0.2}MnO{sub 3} substrate is satisfactorily high at room temperature, YSZ powders were deposited electrophoretically on La{sub 0.8}Sr{sub 0.2}MnO{sub 3} substrate without any treatment such as metal coating. Open circuit voltage of SOFC where YSZ film prepared by EPD was applied, increased by repeating the deposition and calcination cycles. 6 or more times in repetitions were required to obtain YSZ film without gas leakage. A planar type SOFC fabricated by using Ni as anode, attained anmore »« less
Enhancing Electrophoretic Display Lifetime: Thiol-Polybutadiene Evaporation Barrier Property Response to Network Microstructure

Thesis/Dissertation Cook, Caitlyn Christian

An evaporation barrier is required to enhance the lifetime of electrophoretic deposition (EPD) displays. As EPD functions on the basis of reversible deposition and resuspension of colloids suspended in a solvent, evaporation of the solvent ultimately leads to device failure. Incorporation of a thiol-polybutadiene elastomer into EPD displays enabled display lifetime surpassing six months in counting and catalyzed rigid display transition into a flexible package. Final flexible display transition to mass production compels an electronic-ink approach to encapsulate display suspension within an elastomer shell. Final thiol-polybutadiene photosensitive resin network microstructure was idealized to be dense, homogeneous, and expose an elasticmore »« less
