Microcapsules diffuser screen for speckle noise reduction

We make a proposal about the microcapsule diffuser screen with the purpose of reducing the speckle noise on a laser display. This microcapsule diffuser screen has a screen surface in which microcapsules containing charged diffuser particles are applied, where an electric field is charged from the outside, and, thus, the diffuser particles in the capsule are randomly agitated to reduce the speckle noise. In this paper, the speckle noise reducing effect of this screen is studied as well as the reducing effect with respect to the conditions such as the drive conditions and amount of the diffuser particle in the microcapsule.
