摘要： The present invention provides a method and apparatus for storing image data for successive frames in a frame buffer. Specifically, the method and apparatus allow for a display-sized frame buffer to be utilized where a host system provides image data in a format different from that which the display requires to be written to it while retaining the beneficial aspects of concurrent read and write operations from and to the frame buffer. Using this method a buffer controller receives image data from a host system in a first format (e.g. row-by-row) and writes it to the frame buffer in the first format. When the buffer is completely filled with the first frame, it is read out in a second format (e.g. column-by-column) by the buffer controller and provided to a display driver that writes the data to the display. As the first frame is read out in the second format, the buffer controller receives image data for a second frame from the host system in the first format, but rotates it before writing it to the frame buffer such that it is written to the frame buffer in the second format. This rotation allows the buffer controller to write to the frame buffer and the display driver to read from the frame buffer concurrently, despite the different image data format requirements of the host system and display. When the second frame is completely written to the buffer in the second format, the buffer controller then reads the buffer in the first format, and writes it to the display. At this point the process repeats. Thus, the benefits of concurrent read and write are preserved.

摘要： Systems and methods for improving frame rate in a bi-stable display, e.g. MEMS display devices, are disclosed. Lines are selected for skipping during updates based on the desired frame rate and the visual effect of skipping the particular line. In order to determine the amount of time to update a row a physical parameter, such as temperature or the accumulated charge applied to a row or column, is measured. The drive schedule itself involves skipping a row or column based upon a priority value being associated with at least one row or column. The priority may be set based on colour or when the row or column was last scanned.

摘要： Electromechanical devices such as MEMS can be controlled by "drive schemes" comprising electrical signals applied to the display to cause selective actuation or release of the electromechanical devices. In some drive schemes, all pixels on a line are released during a phase when a release voltage is applied along the common line. In some invention embodiments, the release phase sets the common line voltage to the maximum segment drive voltage for a portion of the release phase and the minimum segment drive voltage for the remainder of the release phase. This ensures that all electromechanical devices have a resulting voltage of zero during a portion of the release phase sufficient to release the devices without regard to the segment line voltages. This scheme eliminates slow and no release problems and also eliminates the need for additional voltage transitions on the segment lines.
摘要翻译：诸如MEMS的机电装置可以通过包括施加到显示器的电信号的“驱动方案”来控制，以引起机电装置的选择性地启动或释放。在一些驱动方案中，沿着公共线施加释放电压的相位期间，一行中的所有像素被释放。在一些发明实施例中，释放阶段将释放阶段的一部分的公共线路电压设置为最大段驱动电压，并且在释放阶段的其余部分设置最小段驱动电压。这确保所有机电装置在释放阶段的一部分期间具有零的所得电压，足以释放器件而不考虑线段电压。该方案消除了缓慢和无释放问题，也消除了对分段线路上额外的电压转换的需要。
