Abstract
Systems, apparatuses and methods are provided for increasing the aperture ratio of a display by increasing the total travel distance of respective light modulating bodies in a display while maintaining fast switching speeds. Increasing the total travel distance allows for a larger aperture ratio in a display, which provides greater power savings and increased display brightness. The total travel distance of a light modulating body includes the distance the body travels from an open position to a closed position, and vice-versa. In one example, the travel distance of a light modulating body (e.g., any of the light modulators as described above) is asymmetric: from a neutral position, the body travels a greater distance in a first direction than in a second direction.
