Abstract: Embodiments are directed to a backlight integrated membrane for a keyboard. In one aspect, an embodiment includes a keyboard having a key cap. A feature plate may be positioned below the key cap and a membrane may be positioned below the feature plate. The membrane may include a transparent substrate optically coupled to a light emitting element. The membrane may also include electrical traces for a key switch disposed on the transparent substrate. The embodiment may further include a domed structure positioned on the membrane and configured to actuate the key switch when depressed.
