Fabrication of electrophoretic display panel using prepatterned barrier rib
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.
