Abstract:
An apparatus for reduced display blur may include a display that displays consecutive frames. The apparatus may also include a backlight that intermittently illuminates the display, with variable timing, to render visible each of the consecutive frames. The apparatus may further include a prioritization element that, for each given frame within the consecutive frames, determines a field of interest within the display. The apparatus may additionally include a control element that, for each given frame within the consecutive frames and responsive to the field of interest determined by the prioritization element for the given frame, controls the timing with which the backlight illuminates the display such that the backlight illuminates the display after the display response time has passed for the field of interest within the display for the given frame and finishes illuminating the display before the field of interest within the display is modified for a subsequent frame.
