ABSTRACT:
An electronic device such as a personal digital assistant (PDA), a data terminal, a computer (particularly a portable computer) or a television (particularly a portable television), having a display (10) and a display driver (20). An ambient radiation sensor element (12) senses ambient radiation incident on the display; and an ambient radiation modulation measuring element (104) measures a frequency of modulation of ambient radiation sensed by the ambient modulation sensor element (12) The display driver (20) provides a display scanning signal to the display (10) at a frame rate synchronized to the modulation frequency of the ambient radiation.
