Keyboard graphic overlay
GGI International
MAIN FUNCTION:
The function of the graphic overlay is to display the cosmetic portion of the assembly, such as texts, colors, pictograms, display windows, key functions, selective texturing, etc.
This component acts as an intermediary between the user and the machine by depicting individual functions of a particular assembly.
Tactile interaction: Through touch, carefully designed embossing patterns and surface treatments.
Visual perception: Using colours, backlighting, textures, various fonts and embossing patterns.
SECONDARY FUNCTION:
The graphic overlay also protects the underlying functional layers of the membrane switch keypad. Certain graphic raw materials can also contribute to shielding the keypad assembly (such as polyester).
MANUFACTURING:
Membrane switch keypad graphic overlays designed by GGI International range from polycarbonate, polyester and poly blends available in a wide range of thicknesses and surface finishes. Graphics and colors are applied to the overlay raw material by using the following processes:
Silkscreen printing (Either UV or conventional)
4-color process screen printing
Digital printing
GGI International also offers a wide range of embossing/ forming possibilities as well as CNC and laser-cutting.
