Abstract

In a gas panel display device in which information is generated for display by coincident selection or orthogonal electrodes, a manual entry device enables the operator to communicate with the computer to which it is attached and to edit the display, prior to transmission to the computer, without an alphanumeric keyboard. Gas panel 1, having a predetermined area for character display, includes a transparent overlay area 3 on the panel surface in which elemental areas of stannous oxide film are positioned to correspond to the predetermined character configuration of the display. Each area 3 is connected through conductors 5 and 7 to one side of edge connector 9. The other side of connector 9 is connected through lines 11 and timing and control circuit 13 to computer 15. Information tables 17.

Gas Panel Manual Entry Device

In a gas panel display device in which information is generated for display by coincident selection or orthogonal electrodes, a manual entry device enables the operator to communicate with the computer to which it is attached and to edit the display, prior to transmission to the computer, without an alphanumeric keyboard. Gas panel 1, having a predetermined area for character display, includes a transparent overlay area 3 on the panel surface in which elemental areas of stannous oxide film are positioned to correspond to the predetermined character configuration of the display. Each area 3 is connected through conductors 5 and 7 to one side of edge connector 9. The other side of connector 9 is connected through lines 11 and timing and control circuit 13 to computer 15. Information tables 17. Positioned at one side or on corners of panel 1, are also overlays which include alphanumeric or special characters utilized in the display. Grounded electrical pen 19, connected through conductor 21 to computer 15, is adapted to erase information positioned in elemental area to which such pen is brought into contact. When pen 19 is applied to a selected character area within table 17 and then reapplied to the specified area 3, it causes the character selected from table 17 to be inserted in the specified area 3. When pen 13 is used to erase or insert a character from table 17, a signal is transmitted through circuit 13 directing computer 15 to g...
