MOLECULAR CRYSTALS AND LIQUID CRYSTALS, v.424, pp.65 - 73
Abstract
Fabrication process of electrophoretic display panels was investigated by ulilizing transparent soft mold press, which enables to guide uniform packing of charged TiO2 particles 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 similar to 3.0 Kg(f)/cm(2) of pressure at 60 similar to 90degreesC, the photosensitive film was exposed to UV light at 865 nm in the range of 800 similar to 2,000 mJ/cm(2). The transparant 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
