Optical system design

Abstract

This invention discloses an optical system design, which is used in a liquid crystal display apparatus. The optical system design at least comprises a light generation module, a circular polarization module and a liquid crystal light valve, wherein the light generation module is used to generate a light, the circular polarization module is used to modulate the polarization state of the light to a circular polarization state, and the liquid crystal light valve is used to modulate the polarization state of the light, so as to modulate the intensity of the light to show the image. The optical system design is able to solve the problem of fringing-field effects.
