A keyboard system with changeable key displays includes a keyboard having multiple keys, each key having a transparent housing and a display panel disposed inside the transparent housing. The display panels are capable of displaying different indicia based on different control signals triggered by a user of the keyboard system. The keyboard system includes a printed circuit board (PCB) membrane connected to each display panel using one or more connectors, such as spring loaded pins, solid connectors, or flexible connectors. The PCB membrane receives data signals relevant to the indicia of the key displays and processes the data signals for display of the indicia by the display panels.
