Abstract
A hologram display device includes a light generator generating light, a spatial light modulator forming an interference pattern to interfere with the light, and a controller providing interference data to the spatial light modulator to form the interference pattern. The spatial light modulator includes a first area in which pixels are arranged in a first pattern, and a second area in which pixels are arranged in a second pattern. The controller includes a data generator generating first interference data for the first area and second interference data for the second area, a compensator generating first correction data based on the first interference data and second correction data by correcting the second interference data, and an output unit generating the interference data based on the first correction data and the second correction data.
