Abstract

The display system permits electrical inputs to be made. Such a system can, for example, be employed in conjunction with an airline reservation system, with a map being initially displayed and contacts closed adjacent to the origin and destination points. A calendar can then be displayed and a contact closed adjacent to the date for which the reservation is made.

Translucent Elastic Diaphragm Switch

The display system permits electrical inputs to be made. Such a system can, for example, be employed in conjunction with an airline reservation system, with a map being initially displayed and contacts closed adjacent to the origin and destination points. A calendar can then be displayed and a contact closed adjacent to the date for which the reservation is made.

The system consists of a glass screen 10 through which image 12 is projected by light source 14 and lens 16 onto the front surface of transparent, elastic diaphragm switching array 18. The latter is bonded to screen 10 and the screen and switching array are held together in frame 20.

The right-hand drawing is an expanded view of the display system portion enclosed in circle 22. Array 18 has a laminar construction with substrate 24 being adjacent to screen 10. Substrate 24 can be, for example, transparent MYLAR* having a conductive copper line 26 etched on it. Line 26 is thin enough so as not to interfere with the viewing of the image on screen 10. * Trademark of

Insulating separator sheet 28 of, for example, clear plastic overlays substrate
24. Sheet 28 has a plurality of apertures 30, one of which is shown. MYLAR diaphragm 32 having a thin copper line 34 etched on it overlays sheet 28. Since the junction of line 26 and line 34 can be difficult to detect because of the thinness of the lines, a thin, relatively large layer of hard gold...
