Abstract

The writing surface is at least partially transparent, with a flat display plate of the LCD type provided. The writing surface is placed on top of the LCD plate so that the two form a common plate for recording and reproduction. The common plate is combined with a flat thin casing to form a compact assembly. The casing incorporates electronic components controlled by the writing surface monitor, and is connected to the pen via a flexible electrical cable. Connection may accordingly be maintained with a main computer, word processor modem. The connection may be wire-less or by a cable. - The electronic components comprise writing surface logic, possibly a correlator, a micro-computer, an external memory and a display logic. The writing surface logic is connected to the pen via a cable. The display logic is connected to excitation inputs on the display plate.
