Display And Input Device
First Claim
1. A display and input device, comprising:
- a substrate comprising a front surface and a rear surface;
a plurality of layers provided on the front surface of the substrate, the plurality of layers being operable as a display viewable from the front surface side of the device; and
circuitry connected to the substrate for detecting capacitive coupling between a user'"'"'s finger and the substrate such that the substrate is operable as a touchpad for sensing a user'"'"'s finger touching, or being located in close proximity to, the rear surface of the substrate.

Abstract
A display and input device, comprising a substrate (30), for example a flexible conducting foil, comprising a front surface (8) and a rear surface (10); a plurality of layers (32, 34, 35, 36, 37, 39) provided on the front surface (8) of the substrate (30), the plurality of layers (32, 34, 35, 36, 37, 39) being operable as a display, for example an electrophoretic display, viewable from the front surface side of the device; and circuitry (52, 54) connected to the substrate (30) for detecting capacitive coupling between a user'"'"'s finger (12) and the substrate (30) such that the substrate (30) is operable as a touchpad for sensing a user'"'"'s finger (12) touching, or being located in close proximity to, the rear surface (10) of the substrate (30).

10. Use of a display device as a combined display and input device, the display device comprising a substrate comprising a front surface and a rear surface and a plurality of layers provided on the front surface of the substrate the plurality of layers being operable as a display, wherein the use as a combined display and input device is implemented by using the rear surface of the substrate as a capacitive coupling sheet.
