Systems and methods for display systems with dynamic power control

摘要

Methods and systems to dynamically adjust a voltage supply of a display are provided. Systems are provided to receive a digital data input indicative of an amount of luminance to be emitted from the display, to determine a desired supply voltage to supply to the display based on the received digital data, and to adjust an adjustable voltage supply according to the determined desired supply voltage. Furthermore, the methods and systems disclosed herein provide for dynamically separately controlling supply voltages supplied to distinct subsections of the display. Systems and methods are also provided for operating a display device in an idle mode by turning off subsections of the display that would otherwise be shown dark and thereby save energy required to program the subsections with display information.

1. A system for driving a display, the system comprising:
multiple pixel circuits arranged in an array, each of said pixel circuits comprising a light emitting device and a driving transistor for conveying a driving current through the light emitting device; a controller for determining when said display is to be in a standby mode; and multiple frame buffers pre-loaded with image data for programming only selected pixel circuits when the display is in a standby mode.
