Abstract
A holographic display device includes a backlight unit for emitting light and a spatial light modulator. The spatial light modulator includes a plurality of pixels and a color filter layer including a plurality of color filter groups. The pixels are arranged in a zigzag form and are configured to modulate at least one of the amplitude and phase of the light. Each of the color filter groups includes a first sub-group including a plurality of first color filters, a second sub-group including a plurality of second color filters, and a third sub-group including a plurality of third color filters, and each of the pixels is aligned with one of the first color filters, the second color filters, and the third color filters of the color filter layer.

A holographic display device comprising:
- a backlight unit for emitting light;
- and
- a spatial light modulator comprising:
- a plurality of pixels arranged in a zigzag form, the pixels being configured to modulate at least one of the amplitude and phase of the light;
- and
- a color filter layer comprising a plurality of color filter groups, each of the color filter groups comprising a first sub-group comprising a plurality of first color filters, a second sub-group comprising a plurality of second color filters, and a third sub-group comprising a plurality of third color filters,
- wherein each of the pixels is aligned with one of the first color filters, the second color filters, and the third color filters of the color filter layer.
A holographic display device comprising:
- a backlight unit for emitting light;
- a spatial light modulator comprising:
- a plurality of pixels configured to modulate at least one of the amplitude and phase of the light;
- and
- a plurality of first color filters, a plurality of second color filters, and a plurality of third color filters, the first, second, and third color filters being arranged in a zigzag form, each of the pixels being aligned with one of the first color filters, the second color filters, and the third color filters;
- and
- a field lens on the spatial light modulator, the field lens comprising a plurality of first pattern areas that correspond to the first color filters and allow light having a first color to be transmitted therethrough, a plurality of second pattern areas that correspond to the second color filters and allow light having a second color to be transmitted therethrough, and a plurality of third pattern areas that correspond to the third color filters and allow light having a third color to be transmitted therethrough.
