Display device.

摘要

A display device has a lattice of pixel elements (20) each selectably settable. A method of operating the device comprises the steps of receiving a signal representing a picture for display and time-multiplex addressing collections of pixel elements a plurality of address times for each picture. The addressing step includes setting a group of collections, said group consisting of a plurality of collections spaced apart in the addressing sequence such that the collections in said group form a series with adjacent collections having a temporal separation in the addressing sequence exhibiting a geometric progression with a common ratio N being an integer corresponding to 3 or more. The temporal separation is a logical consequence of the order in which the collections are scanned. Such an addressing step increases the number of grey levels which can be produced.
