Reliability of prototype microcapsule diffuser for speckle noise reduction in laser displays

Abstract

-A microcapsule diffuser of the transparent type is proposed to reduce the speckle noise generated on a laser display. This diffuser has a microcapsule that is secured between two transparent electrodes. The microcapsule contains light diffusion particles that are electrically charged. Because the particles in the microcapsules are moved by the electric field, the proposed device reduces speckle noise. This paper reports the results of one study of the device reliability.

Microcapsules diffuser screen for speckle noise reduction

“…To cope with these disadvantages, Okagaki et al published a paper proposing a microcapsule Diffuser containing electrically charged diffuser particles that moved about depending on an external electric field. 4 The paper also reported the basic configuration of the single microcapsule and its reliability.…”
