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.
A backplane device for a light source matrix or for a light source matrix wherein a light source is a LED or an OLED, wherein a pixel circuitry of the backplane device is assigned to a light source of the light source matrix for controlling the light source, wherein one light source and one pixel circuitry constitute a pixel, wherein the pixels of the light source matrix are classified according to a pixel characteristic, wherein the order of switching the light sources on or off depends on the pixel characteristic and not necessarily on the location of the pixel on the backplane device, wherein a current being applied to the light sources is controlled by at least one driver, wherein the at least one driver is electrically connectable to at least one pixel and the at least one driver is not belonging to the pixel circuitry of the pixel.
A backplane device for a light source array or a backplane device for a light source matrix or a backplane device for a light source matrix in a display device for generating at least one of a two-dimensional and three-dimensional representation of a scene or of content, the light source array or the light source matrix comprising pixels having pixel addresses and being electronically controllable by the backplane device for assigning pixel values to the pixels, the backplane device comprising at least one light source for each pixel, at least one analog line and at least one pixel addressing means, wherein such a pixel addressing means comprises x-addressing lines and y-addressing lines, wherein every pixel is connected to an analog line, to an x-addressing line and to a y-addressing line, wherein as a pixel value assigning scheme a generating means is adapted to generate a current characteristic to be applied to the at least one analog line such that the current characteristic depends on the pixel values to be assigned to the pixels, wherein the backplane device is adapted such that the pixel addresses are determined depending on the generated current characteristic as a pixel addressing scheme and such that the generated current characteristic is applied to the at least one analog line for the purpose of assigning the pixels value to the pixels.
