A 9-inch Flexible Color Electrophoretic Display with Projected Capacitive Touch Panel and Integrated Amorphous-Silicon Gate Driver Circuits

摘要

In order to bring Ebook reader to the next stage, we have developed a prototype and concept design that combine flexible color electrophoretic display (EPD), flexible projected capacitive touch panel (TP) and amorphous-silicon gate driver circuit on array (GOA) technologies. This prototype has been fabricated successfully with the white reflectivity of 23.5%, contrast ratio of 16:1 and 16 gray-level color images. In terms of the flexible TP, it is capable of detecting multi-touch events and transmittance is more than 73.2%. GOA circuit operation is also verified with a 9-inch flexible color EPD.
