Microcapsules as an electronic ink to fabricate color electrophoretic displays

Preparation of black pigment with the Couette–Taylor vortex for electrophoretic displays

“…EPDs have been intensively researched because of their advantages: high contrast, wide viewing angle, less eye fatigue, low power consumption, and excellent flexibility (Bert et al, 2006;Chen et al, 2003;Chung and Jean, 2007;Comiskey et al, 1998;Kim et al, 2005Kim et al, , 2014Lee et al, 2013;Oh et al, 2009;Park et al, 2013;Sim et al, 2012;Sun et al, 2013;Yin et al, 2011;Zhao et al, 2011). EPDs basically consist of two parallel electrodes, a dielectric fluid, and two charged pigments which are white and black.…”

Partially crosslinked P(SMA‐DMA‐St) copolymer in situ modified RGB tricolor pigment particles for chromatic electrophoretic display

“…Another CEPD composed of tricolor electronic ink units containing tricolor electrophoretic particles and corresponding suspension may be a reliable avenue to achieve CEPD with high brightness and contrast. [9][10][11] Studies were focused on the preparation of tricolor electrophoretic particles for CEPD recently. Both of the encapsulated-dye and modified-pigment were applied for synthesis of electrophoretic particles.…”

Surface modification of organic pigment particles for microencapsulated electrophoretic displays

“…Kang et al prepared polymer nanoparticles by free-radical polymerization of styrene and 4-vinylpyridine, encapsulating organic dyes such as Acid Blue 25, Acid Red 8, and Acid Yellow 76 [5]. Kim et al used laser printer toner particles modified with wax materials to fabricate colored microcapsules containing cyanewhite, magentaewhite and yellowewhite pigment pairs [6]. However, the weakness of inorganic [7,8] and polymer particles [9] in chroma and light reflectance was known to influence the color saturation of display.…”
