SUBSTANCE: to bring separate single-pixel indicators and separate logic pixels into conformity, a control table is used, which determines the order of displaying image data on the screen of a display device. One single-pixel indicator and one logic pixel correspond to an arbitrary element of the control table.

Selection of these data from the logic pixel and activation of that single-pixel indicator are repeated at high speed. The order of arrangement on the image data plane of geometric centres of non-overlapping or partially overlapping groups from the plurality of logic pixels coincides with the order of arrangement on the surface of the screen of the display device of conditional geometric centres of non-overlapping groups from the plurality of single-pixel indicators, which (groups from a plurality of single-pixel indicators) correspond to those groups from the plurality of logic pixels. Each group from the plurality of logic pixels mutually explicitly corresponds to a group from the plurality of single-pixel indicators. To increase brightness of the image displayed on the screen of the display device, that screen contains white-colour single-pixel indicators which are activated to generate light flux according to data calculated based on data contained in logic pixels which correspond to those white-colour single-pixel indicators.
