IMAGE INPUT/OUTPUT DEVICE
First Claim
1. An image input/output device comprising:
- a switching element formed on a substrate;
a display portion that is formed on the substrate and that includes a display layer and a first pixel electrode and a first common electrode, the first pixel electrode and the first common electrode sandwiching the display layer;
a photoelectric conversion portion that is formed on the substrate and that includes a photoelectric conversion layer and a second pixel electrode and a second common electrode, the second pixel electrode and the second common electrode sandwiching the photoelectric conversion layer; and
an amplification portion that amplifies an output signal from the photoelectric conversion portion,wherein the first pixel electrode of the display portion and the second pixel electrode of the photoelectric conversion portion are electrically connected to each other,the switching element can switch, between an “
on”
state and an “
off”
state, a connection between the first pixel electrode and the second pixel electrode electrically connected to each other and the amplification portion, andthe first common electrode can switch between a constant potential state and a floated state.

Abstract
An image input/output device is provided that can instantaneously write an image by applying an optical pattern and that can acquire information on the written image as image data. This image input/output device includes a TFT (10); a photoelectric conversion portion (20) including a photoelectric conversion layer (21), a photoelectric conversion pixel electrode (22) and a photoelectric conversion common electrode (23); a display portion (30) including a display layer (33), a display pixel electrode (31) and a display common electrode (32); and a charge sensing amplifier (71) that amplifies an output signal from the photoelectric conversion portion (20). The display pixel electrode (31) and the photoelectric conversion pixel electrode (22) are electrically connected to each other; the TFT 10 can switch between the display pixel electrode (31) and the photoelectric conversion pixel electrode (22) electrically connected to each other and the charge sensing amplifier (71); and a display common electrode (32) can switch between a constant potential state and a floated state.
