A hidden display may be used in an apparatus to display information to a user. The display hardware is generally hidden within the apparatus and illuminated information appears on an outside surface of the apparatus to display the information. The hidden display may couple light into a display panel from the inside of the apparatus to provide the illuminated information on the outside surface of the display panel. The display panel may provide diffuse reflection of ambient light on the outside of the display panel such that the display hardware is not visible behind the display panel but without providing a mirror-like reflection. The display may be used in a variety of different apparatuses or devices including, but not limited to, clocks and clock audio devices.
