EMBOSSING AS AN OPTION
The ergonomy and practicability of the keyboard can be additionaly perfected by selective embossing of keyboard's graphic foil's active surfaces – keys. By so doing the keys become more attainable and the switching feeling better. It also enhances the attractiveness and appearance of the entire application. The shape of the embossed areas is arbitrary.
TRANSPARENT SURFACES
Indispensable parts of almost any interface between the user and the device are the display and the neccessary light signalization. A broad specter of various treatments of a graphic foil enables the integration of transparent surfaces of different quality within every membrane keyboard. Selective adjustment of graphic foil's certain surfaces makes possible for the use of LCD and LED displayes. A perfect clearness and transparency of the keyboard can be achieved if needed as well as only semi - transparency in various colour shades.
CHANGEABLE INFORMATION
By inserting information stripe pockets adjusting of inscriptions and funtions of any key and changing of arbitrary inscriptions on the keyboard in possible. This way the feasibility of making a basic keyboard type which can be modified separately on any device is formed. The pocket is equipped with a transparent window on a graphic foil and with an entry for the carrier of changable signs. One can find the entry on the side or at the back of the keyboard which preserves IP standards. The pocket position is conditionally arbitrary and depends on the keyboard configuration. In some types of keyboards the pocket can be found at the position of keys.
ELECTRONIC COMPONENTS INTEGRATION
Miniaturisation of electronic components has additionaly improved the usefullness of mebrane keyboards because it enabled their insertion in the keyboard. The insertion of SMD LED diodes simplificates the mechanic construction of the device and is very widespread.
The additional increase in level of integration brings the option of combining the membrane keyboard with PCB which is the carrier of conductive connections between keys and which enables the integration of other electronic components.
