Abstract:
A method of driving a group of pixels in a matrix display device, the method comprising:dividing the group of pixels in first and second subgroups of pixels, wherein pixels belonging to the first subgroup require a first change of voltage level and wherein pixels belonging to the second subgroup require a second change of voltage level; inductively coupling the first subgroup of pixels to an intermediate voltage level between a first voltage level and a second voltage level; inductively coupling a second subgroup of pixels to the said intermediate voltage level when the first group of pixels almost reaches the intermediate voltage level; decoupling the first group of pixels from the intermediate voltage level when the first group of pixels almost reaches the intermediate voltage level, wherein the first subgroup of pixels are kept in a high-impedance state after the decoupling; and decoupling the second group of pixels from the intermediate voltage level when the second group of pixels substantially reaches a local extreme voltage level relative to the intermediate voltage level.
