Article Synopsis
- A novel particle-based display medium and driving mechanism have been created for electronic paper displays, utilizing polarized particles that form chains through dipole interactions in an electric field.
- The study involved measuring optical properties, such as transmittance and reflectance, of varying particle concentrations and thicknesses in a display medium primarily made of polystyrene particles suspended in water.
- Results indicated that applying electric fields significantly enhanced the reflectance and contrast of the display, demonstrating potential for improved image clarity in programmable electronic displays.
Transmittance tuning by particle chain polarization in electrowetting-driven droplets.
Biomicrofluidics
December 2010
A tiny droplet containing nano∕microparticles commonly handled in digital microfluidic lab-on-a-chip is regarded as a micro-optical component with tunable transmittance at programmable positions for the application of micro-opto-fluidic-systems. Cross-scale electric manipulations of droplets on a millimeter scale as well as suspended particles on a micrometer scale are demonstrated by electrowetting-on-dielectric (EWOD) and particle chain polarization, respectively. By applying electric fields at proper frequency ranges, EWOD and polarization can be selectively achieved in designed and fabricated parallel plate devices.
