Touch sensitive display
First Claim
1. A display comprising a display screen, a plate of a substantially rigid transparent material, mounting means for mounting the plate on the display screen, force sensing transducer means receiving forces via the mounting means for producing a plurality of electrical signals in response to and representative of a force applied to the plate by a tactile stimulus of the plate, wherein:
- said mounting means comprises a film composed of a transparent, elastic, adhesive compound, having a similar refractive index to that of the display screen;
said adhesive compound being applied to one surface of said plate for bonding that surface to the display screen and transmitting said force applied to said force sensing transducer means.
