This is an example of a graphic overlay that has dual texture (window glossed for character clarity). Transparent tinted windows are included to suit different LED colours. The graphic colours have been screen printed and matched to our customers exact specification. The material used in the production of this overlay is hard wearing and suitable for the environment the equipment has to cope with.
This graphic overlay has been digitally printed primarily to offer a low cost alternative for short run requirements. These types of overlay can be pillow embossed to help finger location and maximise click button response. The rear of this panel has an extra polyester film behind the buttons to greatly improve switch button durability.
This example of a non-tactile flexi membrane* switch panel has a different dual texture combination. The base material is a hard coat gloss polyester which offers a scratch resistant surface for LCD windows and button tops. The rest of the front has a very tough UV MR (Mark Resist) texture screen printed over it. This panel also has UV embossing around the button perimiter to enhance finger locations.
This example shows a metal dome tactile membrane* construction that has pillow embossed button tops for easy finger location. This pillow embossing gives both a better click feel from the metal domes below and also enhances the overall styling of the panel greatly.
Polydome tactile button embossing is ideally suited to high volume manufacturing by keeping production costs lower while offering good click button response. This membrane also has SMD LEDs embedded into the panel. Polydome tactile membrane* switch construction can also offer all the features of dual texturing, transparent windows and window tints.
This example shows a polydome tactile button construction including dual texturing. The base material of the graphic layer is a hard gloss polyester for clarity of view through to the large display below with UV MR texture covering the rest of the front. Behind the large clear window are tiny UV dots which keep the rear of the graphic away from the rigid transparent panel below. The assembly of the "flexi membrane switch panel" and the rigid clear backing panel is carried out in a clean room environment with de-ionised air to eliminate "inclusions" during the construction of the membrane here at Screentec.
