Abstract:
Methods and systems relating generally to information displays, and more particularly to systems and methods for setting or dynamically adjusting the illumination pulses of a display or portions of a display on an individual color channel (typically R, G, B) basis. The illumination pulses may be adjusted for a plurality of frames at once, or on a frame by frame basis. The illumination pulses may be controlled for an entire image frame, or the illumination pulse may be controlled on a finer basis, for instance on separate areas or sub-regions of a display. Such adjustments can lead to improved sharpness, brightness, or useable lifetime of the display, and can eliminate or reduce discrepancies of visual artifacts in the visual field by providing separate or variable duty cycle capability on an individual color channel basis to the display for use in combination with display images, particularly for use with close-eye display orientations such as those used in augmented reality or virtual reality applications.
