The disclosure relates to displays. In one arrangement a plurality of pixels are provided. Each pixel comprises a first optical element reversibly switchable between at least two optical states, and a second optical element reversibly switchable between at least two optical states. The first optical element overlaps spatially with the second optical element in an overlap region when viewed from a viewing side of the display, such that an overall optical effect for the overlap region is defined by a combination of the optical state of the first optical element and the optical state of the second optical element. Row signal lines and column signal lines allow individual addressing of each pixel by applying a combination of a row control signal and a column control signal to the pixel. A driving controller applies the row control signals and the column control signals to the pixels. For each pixel, the same row signal line and column signal line can be used to switch the first optical element and the second optical element independently of each other.
