    • 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 (30), includes an array controller (22) configured to assert a potential difference on said MEMS display element during a first portion (100) 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 (101) 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 (22) 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 (22) 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.

    • This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for tuning the white point of a display device. In one aspect, a display device includes a set of display elements configured to output light and electronics configured to drive the display elements. Each display element can have an on-state where a reflective surface can be positioned at a distance from a partially reflective surface such that the display element can reflect incident light. Each distance can be dependent on a bias voltage. At least one of the bias voltages for the display elements can be non-zero in the on-state, and one or more of the bias voltages may be adjustable to control a white point of the display device. The electronics can be electrically connected to the display elements to provide the at least one non-zero bias voltage.
    • 本公开提供了系统,方法和装置,包括在计算机存储介质上编码的计算机程序,用于调整显示装置的白点。 在一个方面,一种显示设备包括一组被配置为输出光的显示元件和被配置为驱动显示元件的电子元件。 每个显示元件可以具有导通状态,其中反射表面可以被定位在与部分反射表面一定距离处,使得显示元件可以反射入射光。 每个距离都可以取决于偏置电压。 显示元件的偏置电压中的至少一个在导通状态下可以非零,并且一个或多个偏置电压可以是可调节的,以控制显示装置的白点。 电子器件可以电连接到显示元件以提供至少一个非零偏置电压。

    • In certain embodiments, an apparatus includes a substrate (20), a first electrode layer (62) over the substrate, and a second electrode layer (63) over the first electrode layer. The second electrode layer includes a first portion (66) and a second portion (67). The first portion of the second electrode layer is configured to move between a relaxed position spaced away from the first electrode layer and an actuated position spaced closer to the first electrode layer than is the relaxed position. The second portion of the second electrode layer includes at least one electrical contact (70) having an end (71) extending generally away from the substrate.
