Abstract
There is provided a driver for a spatial light modulator comprising a plurality of pixels. The driver is configured to receive a hologram of a picture and drive the spatial light modulator to display the hologram on a group of pixels of the plurality of pixels. The driver is further configured to apply a series of phase offsets to the spatial light modulator displaying the hologram, wherein each phase offset of the series of phase offsets is applied to each pixel of the group of pixels for a respective predetermined period of time.

A driver for a spatial light modulator comprising a plurality of pixels, wherein the driver is configured to:
- receive a hologram of a picture;
- drive the spatial light modulator to display the hologram on a group of pixels of the plurality of pixels;
- determine, for each pixel of the group of pixels, a respective voltage offset to be applied to the pixel to achieve a particular phase offset of a series of phase offsets;
- and
- apply the series of phase offsets to the spatial light modulator displaying the hologram, wherein each phase offset of the series of phase offsets is applied to each pixel of the group of pixels for a respective predetermined period of time, and wherein each phase offset applied to the group of pixels causes a phase delay of that group of pixels to be modified by a same value.
A holographic projector comprising:
- a spatial light modulator comprising a plurality of pixels;
- and
- a driver configured to:
- (i) receive a hologram of a picture, (ii) drive the spatial light modulator to display the hologram on a group of pixels of the plurality of pixels, (iii) determine, for each pixel of the group of pixels, a respective voltage offset to be applied to the pixel to achieve a particular phase offset of a series of phase offsets;
- and (iv) apply the series of phase offsets to the spatial light modulator displaying the hologram, wherein each phase offset of the series of phase offsets is applied to each pixel of the group of pixels for a respective predetermined period of time, and wherein each phase offset applied to the group of pixels causes a phase delay of that group of pixels to be modified by a same value.
A method for driving a spatial light modulator comprising a plurality of pixels, wherein the method comprises:
- receiving a hologram of a picture;
- driving the spatial light modulator to display the hologram on a group of pixels of the plurality of pixels;
- determining, for each pixel of the group of pixels, a respective voltage offset to be applied to the pixel to achieve a particular phase offset of a series of phase offsets;
- and
- applying the series of phase offsets to the spatial light modulator displaying the hologram, wherein each phase offset of the series of phase offsets is applied to each pixel of the group of pixels for a respective predetermined period of time, wherein each phase offset applied to the group of pixels causes phase delays of that group of pixels to be modified by a same value.
