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:
a first plurality of pixel circuits arranged in an array, each of the first plurality of pixel circuits comprising a light emitting device and a driving transistor for conveying a driving current through the light emitting device; a first plurality of supply lines each associated with one or more of the first plurality of pixel circuits, the first plurality of supply lines providing driving currents to the one or more of the first plurality of pixel circuits associated therewith; an adjustable voltage supply configured to provide a supply voltage to at least one of the first plurality of supply lines; a controller for determining, based on digital data indicative of an amount of luminance to be emitted from the first plurality of pixel circuits, an output level from the adjustable voltage supply to apply to the at least one of the first plurality of supply lines, the output level being sufficient to enable the one or more of the first plurality of pixel circuits associated with the at least one of the first plurality of supply lines to emit light according to the digital data.
