  • System and method for providing a variable refresh rate of an interferometric modulator display
    Patent number: 8878825
    Abstract: Embodiments includes methods and systems for updating display devices at a variable refresh rate. One embodiment includes a method of updating an image displayed on a display device. The method includes setting an indicator to a first state that indicates that image data has been received subsequent to a previous update of a display device and periodically updating at least a portion of the display device to display the image. The updating is deferred for at least one period when the indicator is in a state other than the first state. In another embodiment, updates of the display are substantially asynchronous and occur as the processor writes data to one or more shift registers. When a shift register is filled, for example, having received data for a row within the display, the data in the shift register is written to the display. Other embodiments include methods of manufacturing such devices.
