Display driver circuit including high power/low power interfaces and display system

Abstract

A display driver circuit can include an input selector circuit configured to receive first display data from a high power processor circuit and configured to operate in a normal mode in which the first display data is provided and in a dormant mode in which no image data is provided to the input selector circuit and configured to receive second display data from a low power processor circuit that is configured provide the second display data when the high power processor circuit is in the dormant mode. A controller circuit, can be coupled to switch the first display data or the second display data through the input selector circuit based on the mode of operation of the high power processor circuit.
