摘要:
Apparatus and methods of actuating MEMS display elements are disclosed. The disclosed embodiments can be incorporated into other drive schemes for MEMS display elements. In one embodiment, an apparatus for controlling a MEMS display element to display a frame of video data, said MEMS display element comprising a portion of an array of MEMS display elements, includes an array controller configured to assert a potential difference on said MEMS display element during a first portion of a frame display write process to place the MEMS display element in a first display state, and to assert a potential difference on said MEMS display element during a second portion of the frame display write process to place the MEMS display element in a second display state to display the frame of the video data, where the first display state is different from the second display state. In another embodiment, an array controller asserts a large potential difference across a MEMS display element to affect charge build up and an offset voltage level. In another embodiment, an array controller asserts a series of pulses to rapidly switch the MEMS display element between states to overcome adverse conditions that may affect the operation of the MEMS display element.
