发明名称 METHOD AND APPRATUS FOR MINIMIZING FALSE IMAGE ARTIFACTS IN A DIGITALLY CONTROLLED DISPLAY MONITOR
摘要 <p>This invention is directed to improve visual effects on digital display devices that use time and space modulation methods to display grayscale values. A distributed line technique is utilized to provide grayscale capability. The grayscale display is illuminated by energizing pixels of a weighted grid of eight line addresses. The first grid line illuminates pixels based on the first selected bit of the grayscale value for those pixels, the second grid line pixels are illuminated based on the second selected bit of the grayscale value for those pixels, the third grid line pixels are base on the third selected bit of the grayscale value for those pixels, etc. until all pixels for all eight grid lines have been selected. Thereafter, a second set of grid lines is accessed during the second addressing period, a third set is accessed during the third addressing period, and so forth until all grid sets have been accessed. There are N grid sets where N is the number of time slots allocated per frame time. The visual grayscale brightness of each pixel is determined by the selection of the grid sets and the time slot allocated for the grid sets. The bit value selection, grid set allocation, and time slots are chosen such that the grayscale values are scattered in time and space so that the perception of visual disturbances and other perceived artifacts are avoided.</p>
