This disclosure describes techniques for reducing power consumption of a display device. According to these techniques a display device is configured to determine whether an image to be displayed by the display device has become static. In response to identifying such a static image the display device may operate in a static image mode. According to the static image mode the display device may read a current frame of image data modify the current frame of image data to generate a modified frame of image data with a reduced size and store the modified image data in memory. The display device may read the modified image data from memory to present the static image which may reduce power consumption of the display device.
