Abstract: An electronic device (100) includes a display (106) configured to display a content, an input device (104) and a microprocessor (108) operatively coupled to the display (106) and the input device (104). The input device (104) includes a touch screen (112) and a key array (114) positioned on the touch screen (112). The touch screen (112) at least partially covers the display (106), and the key array (114) includes a plurality of keys. The input device (104) is configured to generate an input signal when at least one of the keys in the key array (114) is pressed to touch the touch screen (112). The microprocessor (108) is configured to control the content displayed on the display (106) in response to the input signal received from the input device (104).
