Abstract

The computer modelling of projection TV screen with additive and subtractive multicolor formation was made. The neutral polarizers with phase compensator films were shown to be suitable for LC subtractive color systems instead of color polarizers. The advantages of such construction of subtractive color systems include the application of three identical STN cells. This approach considerably simplifies the technology and results in a lower price of the color projection systems. The additive LC screen can be also produced on the basis of neutral polarizers and phase retardation plates instead of the conventionally used microfilters. The phase retardation plates can be generated, using photoanisotropic polymer films. According to calculations, the proposed construction of an additive LC screen enable to increase the brightness several times as much as compared with usual configurations.
