The present invention relates to a keyboard with a plurality of keys with key switches that are covered by a flexible display for displaying individual labels of the keys whereby the label can be changed during operation of the keyboard by appropriate control of the keyboard. The flexible display is pre-shaped into a non-planar shape to fit on top of the key switches so that each key switch can be activated by depressing the area of the flexible display displaying the key label of the key switch in question. Each key may have a key cap with a transparent top surface with the flexible display mounted underneath the key cap for displaying the individual label of the key viewable through the transparent top surface of the key cap. The keyboard provides tactile feedback similar to a conventional high quality keyboard.
