A rollable, organic electrophoretic QVGA display with field-shielded pixel architecture

A 100-mu m thin QVGA display was made by combining a 25-mu m thin organic transistor active-matrix backplane with an electrophoretic display film. High contrast and low crosstalk was achieved by the addition of a field shield to the backplane. The display can be bent repeatedly to a radius of 2 mm without any performance loss. Extended mechanical tests at a radius of curvature of 7.5 mm show that the display can be rolled at least 30,000 times without noticeable degradation.
