Method for controlling a display comprising a group of pixels, and system, and display controller

摘要

The frame frequency necessary for known liquid cristal displays to get a good image quality without flickering can be reduced for saving memory capacity by splitting up a group of pixels into at least two subgroups of pixels comprising a first number of pixels located in rows and columns, by establishing per subgroup a second number of pixels which should be activated per time frame, by establishing per subgroup an order for pixels located in said subgroup, and by activating during subsequent time frames subsequent second numbers of pixels in accordance with said order. Said subsequent second numbers of pixels for example depend upon the grey level or colour level wanted for that subgroup. These two-dimensional subgroups allow the spreading of activations, which for example will reduce the flickering. <IMAGE>
