Image Projection System

摘要: A projection system comprises a light source, dichroic mirror for separating white into blue, green and red color beams, halfwave plate converting the direction of polarization, three valves forming optical images depending on picture signal, lenses projecting onto screen. By using plate, p-polarized component or s-polarized emitted from is entered liquid crystal panel. The gradient width spectral distribution entering panel smaller, nonuniformity projected image by changes transmittance characteristic with respect to incident angle reduced.
