Patent Images

1. A method of generating images, comprising:

  • initializing driver circuitry in a display to receive image data corresponding to voltages to be delivered to pixels in the display at a first display refresh rate;

    transmitting the image data from a processor in an electronic device in which the display is located;

    receiving the image data at the driver circuitry;

    storing the image data in a frame buffer located in the driver circuitry;

    generating a first image for display on the display based on the image data;

    wherein when the image data is transmitted using a burst transmission over a high speed data connection, generating the first image for display comprises refreshing the first image at a second display refresh rate greater than the first display refresh rate;

    when the image data is transmitted using a transmission over a low speed data connection, generating the first image for display comprises refreshing the first image at the first display refresh rate;

    wherein the burst transmission comprises transmitting multiple frames of voltages that correspond to the first display refresh rate of the display during a first time period and allowing the processor to idle during a second time period; and

    displaying the first image on the display.
