Integration of LCD and Drive Electronics onto Plastic Film

A new liquid crystal display module integrating a LC cell of reflective type, printed circuits and a driver IC on a piece of plastic (polyethersulfone) is developed for automotive dashboard instrumentation. The module, which includes an LC cell with 22 leads to display, can be interfaced directly to a microprocessor with only 8 external leads. The module is flexible so that compact assembly with the systems is possible.
