Abstract:
A method and system is disclosed for improving the response time of displays, such as liquid crystal displays (LCDs). The method includes receiving a target picture frame and comparing it to a current picture frame. If the comparison shows that a display may be unable to transition from a current pixel intensity level to a target pixel intensity level within a specified time period, then the pixels that correspond to those current pixel intensities that may not be reach target pixel intensities may be overdriven. This overdriving of one or more pixels may allow the pixel to reach the target pixel intensity within the specified time period.
