Optical device and electronic device including the same

An optical device comprising:

• a first display device comprising first pixels configured to emit light of a first color;
• a second display device comprising second pixels configured to emit light of a second color different from the first color;
• a first reflection member configured to reflect light of the first color while transmitting light of other colors than the first color;
• a second reflection member configured to reflect light of the second color while transmitting light of other colors than the second color;
• a spatial light modulator comprising third pixels configured to display a light modulation pattern to modulate a phase of light passing through the first reflection member and the second reflection member;
• and
• a controller configured to control the first pixels, the second pixels, and the third pixels based on an input image.

An electronic device comprising:

• a light source comprising a plurality of first pixels configured to emit light;
• a spatial light modulator comprising a plurality of second pixels configured to display a light modulation pattern to modulate a phase of light output from the light source;
• a memory;
• and
• a processor,
• wherein the processor is configured to generate light intensity data for the plurality of first pixels and light modulation data for the plurality of second pixels based on an input image.
