US 8,553,053 B2 · Adaptive control of display characteristics of pixels of a LCD based on video content

Abstract

Determining pixel behavior type of a pixel or a group of pixels of a LCD and triggering adjustment in drive power of the pixel or the group of pixels based on the pixel behavior type. The pixel behavior type indicates relative motion of areas on the LCD in a video. A pixel behavior determination module directs one or more selected pixels of the LCD to be driven relative slower or faster based upon content of video that the selected pixels display. Operations include identifying an active window from a plurality of windows corresponding to a plurality of applications running on the host device and setting the drive power of those pixels that correspond to the active window based on speed of a video displayed on the active window. Operation may also include adapting LCD drive power on a pixel by pixel basis based upon user input and/or remaining battery life.

Dependent claims

A system for adaptively controlling operation of a Liquid Crystal Diode (LCD) display, the system comprising:

a controller circuit operable to select a first zone of the LCD display for displaying a first video and to select a second zone of the LCD display for displaying a second video, the first video changing at a rate that is relatively faster than a rate at which the second video is changing;
and
pixel drive circuitry coupled to the controller circuit and the LCD display and operable to:
drive pixels of the first zone of the LCD display in a first mode corresponding to a first drive characteristic;
and
drive pixels of the second zone of the LCD display in a second mode corresponding to a second drive characteristic.
