Thin (0.1mm) electroluminescent DFLX lamps easily fit between metal dome arrays and keypads of mobile phones, remote controls, and other keypad devices.
The lamps provide uniform backlighting directly-under each key without affecting the tactile feel of actuation. The lamps feature a durable rubber composition that reportedly survives over a million keypad actuations without degrading. A small IC driver with low current powers the lamps, so little heat is generated.
