Abstract:
A method for controlling light output of a matrix display in a frame period, the matrix display consisting of a plurality of cells,the light generation of the cells being done in small pulses, the frame period being subdivided into a number of sub-fields having at least partly different weights, each of the sub-fields consisting of at least an addressing, sustaining and erasing period, wherein the display panel is subdivided in at least two sections, the cells of one section being addressed in a dedicated corresponding address period, wherein, to each section is assigned a separate addressing period within a sub-field, and an address operation in one section may not overlap in time with a sustain operation in another section, wherein the time distance between the at least two successive addressing periods of the at least two sections is constant within one sub-field, but varies from one sub-field to the other, in particular for the sub-fields with higher weights and wherein the time distance increases in the direction from lower sub-field weight to higher sub-field weight.
