Touch Control Light Display Panels

Modular touch control display panels have design flexibility, reduced part number inventories and enhanced performance. Such panels can be used as standard components of different man/machine interactive display panel assemblies; e.g. for various computer consoles, terminals, etc.

Typical modular panel assembly 8 consists of compartmentalized housing 10, translucent plastic overlay screen 12, translucent touch switch array 14, plug-in adapted light modules 16 and plug-in adapted connectors 18. The connectors provide predetermined via cables 20 to not shown logic circuits. Overlay screen 12 contains printed nomenclature and outlines of touch-switching areas and light- indicating areas. Such areas may coincide; e.g. at back-lit switch points.

Touch-switch array 14 consists of orthogonal conductors separated by a dielectric medium having openings at cross-over points. Touch switch connections are established through such openings by elastic diaphragm switch (EDS) elements located at the cross-overs. Light modules employ light emitting diodes (LED's) to provide area illumination or alphameric indication. The connectors and logic circuits provide various electronic translation functions between the conductors of switch array 14 and the LED's.
