Abstract
A smaller sized flip dot display utilizes a magnetically actuated pixel that rotates between two orientations. The orientations display two different optical states. A simulated dot matrix design improves the aesthetics and consumer appeal, and also permits a flip dot display capable of producing a positive contrast display image with darker colored “ON” pixels contrasting with brighter background and “OFF” pixels by reducing the visibility of the spacing gap between each rotating pixel and the surrounding background. An interwoven configuration of magnetic actuators with a coil around each arm of a U-shaped core may result in lower power consumption, low production cost, and small size required for use in consumer and small mobile devices such as watches and mobile phones.
