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.

First claim

What is claimed is:

1. A method comprising:
processing data to produce first content changing at a first rate and second content changing at a second rate, the first rate relatively faster than the second rate;
logically subdividing a LCD (Liquid Crystal Display) into a first zone corresponding to the first content and a second zone corresponding to the second content;
selecting a first mode of operation having a first pixel response time for the first zone; and
selecting a…
