Abstract :
In this paper, the conductive grids were flexographic printed with solvent based conductive ink. Elastomeric plate with 45° grid of 30μm line and pitch of 0.4mm was prepared. Surface resistance and optical transmittance of the printed film were characterized by two-electrode method and UV-VIS-NIR spectrophotometer respectively. At a comparable transmission level (83% measured at 600nm, without substrate), the sheet resistance obtained (11 ohm/square) by printed grid was about 50% lower than that of high conductivity ITO film (24 ohm/square).
