    Abstract: Keyboard assemblies having reduced thicknesses and methods of forming the same. A keyboard assembly may include a printed circuit board (PCB) and a single membrane sheet adhered directly to the PCB. The single membrane sheet may substantially cover the PCB. The keyboard assembly may also include a group of dome switches coupled directly to the single membrane sheet. Another keyboard assembly may include a group of conductive pads and a group of membrane pads. Each of the group of membrane pads may be adhered directly to a corresponding one of the group of conductive pads. The keyboard assembly may also include a group of dome switches coupled directly to the membrane pads. Each of the group of dome switches may be coupled directly to a corresponding one of the group of membrane pads.

    Abstract: Systems and methods for selective keyboard backlighting with reduced driver circuitry are provided. In one example embodiment, a method includes, inter alia, simultaneously controlling, with a control signal, an output of a first light emitting element that illuminates only one key of a plurality of keys of a keyboard and an output of a second light emitting element that illuminates only one key of the plurality of keys, and maintaining, with a current mirror circuit, uniformity between the output of the first light emitting element and the output of the second light emitting element.
