Flexible touch screen display

摘要

A touch sensitive active matrix display device is provided. The device includes a display fabricated on a first flexible substrate, said display having a viewing surface. The device further includes a touch sensitive sensor including a second flexible substrate, under said display. The touch sensor is operated by touching said viewing surface of said display, and said combined display and touch sensitive sensor is flexible.

主权项

1. A touch sensitive active matrix display device, the device comprising:
a display having a viewing surface; and a capacitive touch sensitive sensor integrated with and under said display, said touch sensitive sensor comprising a flexible substrate, and at least one conductive layer on said flexible substrate; and wherein said capacitive touch sensitive sensor is operable by touching said viewing surface of said display; wherein said display comprises an electronic paper display medium and has a backplane comprising an active matrix, said active matrix having an array of field-effect transistors comprising an organic semiconductor, said transistors configured to control said display; wherein said backplane is disposed on said at least one conductive layer with a dielectric isolation layer between said at least one conductive layer and electroactive layers of said backplane, with said dielectric isolation layer providing electrical insulation between said at least one conductive layer and said electroactive layers of said backplane; and wherein said display and capacitive touch sensitive sensor in combination have a flexibility greater than needed for functionality of operation of said capacitive touch sensitive sensor such that said display and capacitive touch sensitive sensor in combination is bendable as a whole.
