| Abstract Scope |
Informational displays have seen rapid growth in recent years from backlit LCDs to low-powered energy efficient reflective electronic displays. Vibrant full-color reflective displays, however, are still underdeveloped because of the number of different charged pigmentary particles required to generate colors, and their subsequent charge separation that generates a several-second response time.
Herein, we demonstrate an electrophoretic display (EPD) based on engineered core-shell Fe2O3-SiO2 nanoparticles mixed with color enhancing additive particles that provide a combination of pigmentary color and structural colors in the active state. In this work, displays access an improved range of chromatic colors (green, purple, blue, orange) based on device architecture design and display spacing. Fast response time (30-100 ms) was measured at low operation voltages (±1-5 V), which yields a promising low-powered high-performance colored display.
Work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-ABS-850938. |
