Keypad of Samsung phone displays different icons depending on how the phone is being used Samsung Electronics’ upcoming SGH-E950 phone has a feature that stands out from other models: a 1.2-inch OLED (organic light-emitting diode) keypad that can display different icons depending on how the phone is being used.When the slider E950 is not in use, the black-and-white OLED navigation keypad stays dark. Slide the phone open and it turns on, revealing five white icons: one each for music, messages, the phone book, the Internet, and Yahoo’s Messenger, e-mail, and mobile search services. Click through to any menu and the display changes again, offering four-way navigational buttons and an ‘OK’ button in the middle.The keypad also changes when a user activates the E950’s 3.2-megapixel camera, giving the option to zoom in for a closer shot. The center of the OLED keypad displays a camera icon that’s pressed when a user’s ready to take a picture. OLED screens have been used with other phones, usually as the smaller, secondary display on the outside of a clamshell case, rather than as a keypad.The use of OLED screens with keys was largely popularized by Russian designer Artemy Lebedev. Lebedev’s Optimus Maximus keyboard, which will ship later this year, tops each key with a small color OLED screen. These screens allow the keyboard’s keys to be quickly changed for different languages and functions.Samsung’s E950 was unveiled at the CommunicAsia exhibition in Singapore, and will go on sale in Asian markets starting next month. Pricing has not been announced. Technology Industry
