| Summary: | A 96-hour thermal accelerated ageing test was carried out to investigate the stability and failure mode of the water/fluoropolymer/indium tin oxide contact in electrowetting display systems. Three different types of commercial amorphous fluoropolymer were used to prepare the test specimens and 2.7-inch electrowetting display samples. A single fluoropolymer layer design of the electrowetting display sample was adopted in this study. The I-V characteristics of the test specimens and electrowetting display samples during and after the aging test were studied. Optical microscope, scanning electron microscope and energy dispersive spectrum were used to analyze the defect in the water/fluoropolymer/indium tin oxide contact. The failure mode of the fluoropolymer coated indium tin oxide electrode in electrowetting displays in the thermal accelerated ageing test was proposed.
