ABSTRACT:
A solid electrochromic film is used on a semiconductor electrode in a display device permitting the user to write on the display using a light pen. Additional elements, including arrangement of the semiconductor electrodes transversely with respect to counter-electrodes, or providing an electrochromic film on the counter-electrodes, further enhance the versatility of the display device.
