An integrated key and a method of producing the integrated key, wherein the integrated key can be used on an electronic device. The integrated key includes an organic light-emitting layer and a plurality of electrodes, operatively connected to a power source, to activate the light-emitting layer in order to illuminate the key. Furthermore, the light-emitting layer and the electrodes can be arranged into a group of segments or pixels. The segments or pixels can be individually addressable so that they can be selectively activated to from a symbol or words. The key is implemented on a substrate and includes an encapsulation layer to form a cavity for filling with a gaseous species to protect the organic light-emitting layer in the key.

Integration of organic light-emitting components into the keyboard of an electronic device

A keyboard having a plurality of first keys on one side and second keys on the other, separated by a circuit board and a plurality of domes. The circuit board can be activated for entering information in an electronic device by pressing one or more keys on either side via the domes. The keyboard can be fixedly mounted on the cover of the electronic device such that the first keys can be used when the cover is closed and the second keys can be used when the cover is open. The keyboard can also be removably mounted so as to allow a user to change the keyboard side to be used. Alternatively, one side of the keyboard has a touch pad instead of keys.

Double-sided keyboard for use in an electronic device

An integrated keymat or keyboard to be used on an electronic device. The integrated keymat includes a plurality of individual emissive keypads each having a legend or symbol provided thereon. The emissive keypad has a light-emitting source and a plurality of electrodes, operatively connected to a power source, to activate the light-emitting source in order to illuminate the keypads, wherein the connection of the electrodes is controllable so that one or more keypads can be illuminated causing the key indicating marks on said one or more keypads to become more visible. Furthermore, the light-emitting source may include a plurality of segments of pixels which are individually addressable so that they can be selectively activated to form an alphanumeric symbol or pattern. Moreover, the integrated keymat further comprises one or more lens-like pads provided on the keypads to make the legend or symbol on the keypads more visible.

Arrangement for integration of key illumination into keymat of portable electronic devices

A double-sided keyboard having a first keymat and a second keymat located on two sides of a circuit board, wherein the first and second keymats share an activation mat located between the first keymat and the circuit board. The first keymat has a plurality of keys, and the second keymat has a plurality of keys so that any key can be used to activate the circuit board through the same activation mat. The double-sided keyboard can be used on the cover of an electronic device so that the first keymat is used to enter information in the electronic device when the cover is closed and the second keymat is used when the cover is open. Preferably,.the activation mat has a plurality of dome-shaped, electrically conducted sections which make contact with the circuit board when one of the keys is pressed.
