1. An electronic-blackboard type display system comprising:
- a sheet member onto which information is input;
position coordinate detecting means, formed as a body separate from the sheet member and arranged behind the sheet member, for detecting a position of information input on the sheet member; and
control means, to which output data of the position coordinate detecting means is transferred, for processing the information input to the sheet member, wherein the position coordinate detecting means includes a resistor film type, pressure sensitive touch panel and wherein the sheet member prevents the resistor film type, pressure sensitive touch panel from being seen by viewers viewing the electronic-blackboard type display system, wherein the sheet member includes a plurality of information input surfaces.

Abstract
A display system includes a sheet member onto which information is input, and a position coordinate detector such as a pressure sensitive touch panel. The position coordinate detector is formed as a body separate from the sheet member and is arranged behind the sheet member. It detects the position of information input on the sheet member. A computer, to which the output data of the position coordinate detector is transferred, processes the information input to the sheet member. When the sheet member is used as a projection screen, the computer connects to a projector to project the input information onto the sheet member.
