    • The present invention relates to a backplane device (16) for a spatial light modulator (12), especially a spatial light modulator (12) in a display device for generating a two-dimensional and/or three-dimensional representation of a scene or of content. The spatial light modulator (12) comprises pixels (14) having pixel addresses and being electronically controllable by the backplane device (16) for assigning pixel values (15) to the pixels (14). The backplane device (16) comprises at least one electrode (500) for each pixel (14), at least one analog line (22) and at least one pixel addressing means (24). Such a pixel addressing means (24) comprises x-addressing lines (26) and y-addressing lines (28). Every pixel (14) is connected to an analog line (22), to an x-addressing line (26) and to a y-addressing line (26). As a pixel value (15) assigning scheme a generating means is adapted to generate a voltage characteristic (10) to be applied to the at least one analog line (22) such that the voltage characteristic (10) depends on the pixel values (15) to be assigned to the pixels (14). The backplane device (16) is adapted such that the pixel addresses are determined depending on the generated voltage characteristic (10) as a pixel addressing scheme and such that the generated voltage characteristic (10) is applied to the at least one analog line (22) for the purpose of assigning the pixels value (15) to the pixels (14).Furthermore, the present invention relates to a method for operating a backplane device(16) for a spatial light modulator(12).
