Display Apparatus Configured For Image Formation With Variable Subframes

摘要

This disclosure provides systems, methods, non-transitory computer readable media and apparatus for improving power efficiency of display devices. Control logic of a display device can reduce a number of subframes used to display a series of image frames. In some implementations, the control logic can detect a scene change in the series of image frames and reduce the number of subframes utilized for displaying a following image frame. Subsequently, the control logic can monotonically increase the number of subframes utilized for displaying a first set of successive image frames. In some implementations, the control logic may monotonically increase the number of subframes for a first set of image frames and then monotonically decrease the number of subframes for a second set of image frames.

主权项

1. An apparatus, comprising:
an input capable of receiving image data associated with a series of image frames in a video sequence; subfield derivation logic capable of, for each of the image frames in the video sequence, deriving at least one color subfield, wherein each of the at least one color subfields for each image frame identifies a color intensity value with respect to each of a plurality of display elements in a display; subframe generation logic capable of generating a number of subframes for each of the color subfields derived from the image frames in the video sequence, wherein each generated subframe indicates the states of each of the plurality of display elements in the display; and output logic capable of:
outputting to the subfield derivation logic and the subframe generation logic a monotonically increasing number of subframes to generate for a first set of the image frames; andcontrolling the timing of outputting the subframes generated by the subframe generation logic.
