Abstract
A method, a digital driving circuit and a LED display where images to be displayed in successive frames are converted from an n-bit digital image to a (m+1)-bit digital image, where m<n, by truncating, for each pixel, the (n−m) least significant bits or most significant bits of the n-bit digital image, and encoding in the (m+1) bit an indication. Each pixel of the (m+1)-bit digital image is supplied with a first drive current if the (n−m) least significant bits are truncated, and each pixel of the (m+1)-bit digital image with a second drive current if the (n−m) most significant bits are truncated, where the ratio of the first drive current to the second drive current is such that it results in a brightness ratio of 2{circumflex over ( )}(n−m), and where the indication provides information on the drive current to be used.
