A Flexible 7.1-in. Active-Matrix Electrophoretic Display

We have developed a flexible 7.1-inch Quad-XGA active-matrix electrophoretic display using SUFTLA™. The whole panel circuitry including 7.3-milion transistors was successfully transferred onto a plastic substrate without damage. Integrating both scan- and data-drivers made it possible that 3-mega pixels are controlled with only 40 signal terminals. The developed panel fulfills major requirements for e-paper including true flexibility, thinness and lightness.
