Abstract
A flat, high temperature membrane switch display having a display, a rigid substructure with a hole approximately of the dimensions of the display located approximately in its center, multiple switch layers with a hole approximately of the dimensions of the display located approximately in its center, an overlay with a display window approximately of the dimensions of the display located approximately in its center, and a clear part affixed to the overlay by an adhesive.
Claims17
A flat, high temperature membrane switch display window comprising:
- a display having a length dimension and a height dimension;
- a rigid substructure having a center hole of the approximate dimensions of said display located adjacent to the display;
- multiple switch layers having a center hole of the approximate dimensions of said display located adjacent to the rigid substructure;
- an overlay having a display window having the approximate dimensions of said display located approximately in the center of the overlay, said overlay further having an interior side and an exterior side wherein the interior side of the overlay is located adjacent to the multiple switch layers;
- and
- a rigid clear part affixed to said interior side of said overlay by an adhesive wherein the adhesive is affixed only to a peripheral edge of said clear part.
A flat, high temperature membrane switch display window comprising:
- a display;
- a rigid substructure with a center aperture located adjacent to the display;
- multiple switch layers with a center aperture located adjacent to the rigid substructure;
- an overlay with a display window located adjacent to the multiple switch layers;
- and
- means for preventing thermal distortion of said overlay wherein said means comprises a clear part and an adhesive layer affixing said clear part to said overlay, said adhesive layer applied only to a periphery of said clear part.
A flat membrane switch display assembly comprising:
- a display device;
- a rigid structure having an aperture therethrough through which said display device is visible from a front side thereof the rigid structure located adjacent to the display device;
- a flexible, thin, transparent overlay covering said front side of said structure and said aperture;
- a rigid transparent member secured relative to said structure and positioned in said aperture closely adjacent to said overlay to produce a minimal volume airspace between said member and said overlay in an area of said aperture;
- and
- means for sealing said airspace to prevent a leakage of air into or out of said airspace.
