Dynamic light scattering liquid crystal (DLS-LC) device with a low driving field is used to reduce the speckle in the laser pico-projector. The DLS-LC device produces the time-varying scattering patterns, which can eliminate the degrees of temporal and spatial coherences of the laser and achieve a very effective reduction in the speckle contrast.
