Here, proceeding from a previous study, the deformation problem of a viscose fluid is analyzed under simplified conditions as regards the physical model. This viscose fluid is used as the light control organ in the light valve method of large-screen television projection. By using simple approximate relationship, the important properties, such as dynamic behavior, frequency response, stability behavior, and resolution limit of the control layer and their dependence on material and system parameter are discussed in detail. The theoretical knowledge obtained from this analysis agrees to a large extent with the experimental results.
