Abstract

Fabrication process of electrophoretic display panels was investigated by utilizing transparent soft mold press, which enables to guide uniform packing of charged TiO2particles and colored particles for color e-Paper display. For this process, transparent soft mold was prepared by reacting silicone solution(silicone prepolymer/curing agent = 10/1 wt./wt.)into the base mold. While pressed with the transparent soft mold under 1.5 ∼ 3.0 Kgf/cm2of pressure at 60 ∼ 90°C, the photosensitive film was exposed to UV light at 365 nm in the range of 800 ∼ 2,000 mJ/cm2. The transparent soft mold was demolded by rolling up to give electrophoretic display panels with precise geometry. The process of obtaining colored electrophoretic display was also discussed.
