14 . The device of claim 1 , wherein the touch sensor is resistive, capacitive, ultrasonic, infrared, or a combination thereof.
15 . The device of claim 1 , wherein at least a portion of the device is flexible.
16 . The device of claim 1 , wherein the display layer is pre-written.
17 . The device of claim 1 , wherein the display is reflective, transmissive, or transflective.
18 . The device of claim 1 , wherein the imaging material is liquid crystal.
19 . An electronically updatable device comprising one or more of the devices of claim 1 .
20 . The device of claim 19 , wherein the device is a calculator, personal digital assistant, touchpad, writing tablet, notation board, drawing pad, kiosk, menu-driven interface, keyboard overlay, industrial controller, data input device, informational signage, video game, toy, watch, or electronic book.
