<p>A display device has a lattice of pixel elements each selectably settable. A method of operating the display device comprises the steps of receiving a signal representing a picture for display during a display period and illuminating the lattice to produce, during a first interval within the display period, a first light output from the lattice having a first predetermined colour characteristic and to produce at least one additional light output from the lattice. Each said additional light output has a different predetermined colour characteristic and a respective interval within the display period separate from the first interval. The method further comprises the step of time-multiplex addressing blocks of pixel elements a plurality of address times during each interval. The addressing step includes setting a group of blocks, the group consisting of a plurality of blocks spaced apart in the addressing sequence such that the blocks in the group form a series with adjacent blocks having a temporal separation in the addressing sequence exhibiting a geometric progression with a common ratio N being an integer equal to 2 or more. In this way, addressing of the lattice occurs simultaneously with its illumination by the appropriate colour, allowing a greater proportion of the frame time for the addressing operation so that additional addressing information can be utilised.</p> |
