By integrating light guides and scattering elements, BOPLA offers optimal lighting results for night design and daylight. The portfolio of illuminated membrane keypads consists of various designs and technologies which guarantee homogeneous, efficient and energy-saving illumination. In bad light conditions, the illuminated membrane keypads make work much easier, and in this way they ensure a reduction in errors by minimising incorrect operations. Even in dark rooms, this guarantees 100% secure operability. In doing this, the number of keys and their positions, the shape of the keys and the graphic design can be adapted individually to the relevant requirements.

Backlit Profiline for the highest standards
Whether vehicle technology, payment systems or medical technology – thanks to its long operating life, low energy consumption and optimal ease of use, the backlit Profiline membrane keypad is at home in many sectors. The space-saving technology used here incorporates dual-function key inlays which also act as a light guide. A special RGB LED allows a key to light up in various colours – a very wide range of mixed colours in addition to red, green and blue. In this way, different displays are possible inside a single key.

Even light distribution
In addition, with its NLF backlight (Night-Light-Foil) and EL foils (electro-luminescence foils) BOPLA offers two more technologies for even light distribution.. With the use of LEDs, NLF technology makes it possible to realise almost all back-lighting requirements in robust, compact and effective ways, from the single key to a large area. A low mechanical height and mechanical flexibility are additional advantages. EL foils also emit homogeneous light over the entire surface. Normally EL membranes are less than 0.3 mm thick, so they are extremely space-saving.
