Abstract

There is an urgent need for change to meet the requirements of green technology for printed circuits for printed electronics and displays. In this paper, a novel and simple process to manufacture electrodes of fluidic base display at room temperature was proposed. Following our prior researches, the processes combined self-assembly polyelectrolyte (SAP) layer deposition, ink-jet patterning of palladium catalyst, and electroless plating to form an electrode pattern on a polyimide substrate. The patterned, high conductive circuit is applied to fluid based displays, such as cholesterol liquid crystal or electro-wetting displays, which are also color patterned by the printing process to discharge the individual color media onto predetermined flexible substrates. This study demonstrates the ink-jet printing electrodes for a 10.4” cholesterol liquid crystal display on a polycarbonate substrate. The thickness and resistivity of the electrode pattern were measured at about 400±50 nm and o.15 ohm/square, respectively. The Flexure-angular examination indicated, after a 2 mm curvature and 2000 tests, that the variation of resistivity variation was less than 1%.
