Abstract
The present invention relates to a backplane device for a light source matrix. A light source is preferably a LED or an OLED. A pixel circuitry of the backplane device is assigned to a light source of the light source matrix for controlling the light source. One light source and one pixel circuitry constitute a pixel. The pixels of the light source matrix are classified according to a pixel characteristic. The order of switching the light sources on and/or off depends on the pixel characteristic and not necessarily on the location of the pixel on the backplane device. A current being applied to the light sources is controlled by at least one driver. The at least one driver is electrically connectable to at least one pixel. The at least one driver is not belonging to the pixel circuitry of the pixel.
