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.

Driver for a display device

A projection system that facilitates the use of in-situ detection of a change in wavelength, thereby enabling appropriate compensation or corrections to be applied on the fly to improve the quality of the image in the primary image region. In-situ detection in this manner can allow wavelength changes due to both temperature fluctuations and hardware variations to be compensated for simultaneously, thereby reducing the time and expense for end of line hardware testing, and removing the need to perform in-situ mapping of the wavelength as a function of temperature. In this way, the quality of the image provided to a user can be improved in a simpler, more efficient manner.
