Abstract
An information handling system comprising a hardware processor, a data storage device, and a power management unit includes a split keyboard stack structure having a removable tactile input layer and a keyboard sensing hardware structure formed on a multi-layer flexible printed circuit board or on a thin two-sided substrate membrane below a sealed input surface that forms a top surface of a keyboard chassis and onto which a removable tactile input layer is installed. The keyboard sensing hardware structure detects capacitive changes to capacitive fields above the sealed input surface with capacitive sensor pads of a capacitive pads layer and includes a plurality of shielding pads, a light-emitting diode (LED) layer comprising a plurality of LEDs formed coplanar with the capacitive sensor pads, wherein the sealed input surface has a light guide layer integrated to transmit light emitted from the plurality of LEDs up through the removable tactile input layer.
