Abstract— The perceived resolution of matrix displays increases when the relative position of the color subpixels is taken into account. “Subpixel‐rendering” algorithms are being used to convert an input image to subpixel‐corrected display images. This paper deals with the consequences of the subpixel structure and the theoretical background of the resolution gain. We will show that this theory allows a low‐cost implementation in an image scaler. This leads to high flexibility, allowing different subpixel arrangements and a simple control over the trade‐off between perceived resolution and color errors.
