A newly designed curved beam microshutter display device with high aperture ratio

This paper reports a curved beam microshutter display device with a novel part-division design to achieve high aperture ratio. The part-division design which consists of two parts doing respective functions is a simple method to enhance performance of the curved beam microshutter. The proposed device accomplished 68% of the aperture ratio by the fixed shutter plate part and a thermal actuator on the actuator part enabled the device to be actuated with under 2V, which are greatly enhanced values compared with those of the conventional curved beam microshutters reported as 30% and 120V.
