Abstract

The invention relates to the provision of a graphic compression method for pixel data for a display screen and particularly a display screen provided as part of a mobile device. The method includes the splitting of pixels data for the display into quadratic groups of pixels typically 2×2 pixels, and by encoding representing the same with respect to a number of color templates, with a reduced number of bits.
