Method for providing gray scale images to the visible limit on liquid crystal displays

摘要

A method for displaying grey-scale images at a desired grey scale resolution on a display having a matrix of pixels, comprises the steps of: defining a control matrix having a size smaller than the entire display and equal to the desired grey scale resolution of the display, each position in the control matrix having an address assigned such that unintended artifacts in the display are controlled; horizontally and vertically mapping the control matrix into the display such that each pixel in the matrix of pixels in the display corresponds to an address in a control matrix mapped into the display; comparing control matrix address of each pixel in a frame of an image to be displayed on the display to a range of address values and turning that pixel on if the grey scale value of that pixel is within the range of address values, the range of address values arranged in a circular queue and being equal to the grey scale value of that pixel; and shifting the range of address values in the circular queue for successive frame by an amount equal to the grey scale value of the pixel to be displayed.
