Display device
First Claim
1. A method of converting of a first set of initial segments of an image into a second set of updated segments of the image, the method comprising iterative updates of intermediate segments being derived from respective initial segments, a particular update comprising determining whether a particular pixel being located at a border between a first one of the intermediate segments, and a second one of the intermediate segments, should be moved from the first one of the intermediate segments to the second one of the intermediate segments, on basis of a pixel value of the particular pixel, on basis of a first parameter of the first one of the intermediate segments and on basis of a second parameter of the second one of the intermediate segments, characterized in that first a number of iterative updates are performed for pixels of a first two-dimensional block of pixels of the image and after that the number of iterative updates are performed for pixels of a second two-dimensional block of pixels of the image.

Abstract
The invention relates to a display device comprising a liquid crystal material between a first substrate provided with row or selection electrodes and a second substrate provided with column or data electrodes, in which overlapping parts of the row and column electrodes define pixels, and drive means for driving the column electrodes in conformity with an image to be displayed. Such display devices are used in, for example portable apparatuses such as laptop computers, notebook computers and telephones.

- 7. A conversion unit for converting a first set of initial segments of an image into a second set of updated segments of the image, the conversion unit being arranged to perform iterative updates of intermediate segments being derived from respective initial segments, a particular update comprising determining whether a particular pixel being located at a border between a first one of the intermediate segments, and a second one of the intermediate segments, should be moved from the first one of the intermediate segments to the second one of the intermediate segments, on basis of a pixel value of the particular pixel, on basis of a first parameter of the first one of the intermediate segments and on basis of a second parameter of the second one of the intermediate segments, characterized in that the conversion unit comprises computation means for performing first a number of iterative updates for pixels of a first two-dimensional block of pixels of the image and for, after that, performing the number of iterative updates for pixels of a second two-dimensional block of pixels of the image.
