Abstract: An apparatus includes a light modulator configured to modulate light to display frames of images based on display image data, and a controller coupled to the light modulator. The controller is configured to obtain a sequence of image data to be displayed by the light modulator; produce the display image data based on the sequence of image data; transmit the display image data to the light modulator; determine, based on the sequence of image data, to enter one or more sleep modes that reduce power usage by the controller, the light modulator, or an interface between the controller and the light modulator compared to a normal operation mode; and enter one or more extended sleep modes that have lower power usage than the one or more sleep modes if an extended sleep mode signal is detected in the sequence of image data.

Abstract: A controller includes: a processor; and interface circuitry for multiple interfaces. The interface circuitry is coupled to the processor and is configured to: receive load sequences from the processor, the load sequences including a respective load sequence for each of the multiple interfaces, each load sequence including image data intervals and idle intervals; determine a duration for each of the idle intervals; and separately control a sleep mode for each of the multiple interfaces responsive to each of the idle intervals.
