A video projector with liquid crystal microdisplay based on FLCoS- structure is considered, and the new low-voltage ferroelectric liquid crystal (FLC) with a compensated helix as an electro-optical material providing physically realizable continuous gray scale hysteresis-free modulation characteristic is proposed to use in FLCoS. As light sources in RGB color channels the laser diodes of red, green and blue light are proposed to use. To prevent the interference of light beams resulting in the speckle noise appearance in output images it is proposed to input a despeckler – single FLC cell into an optical unit of information readout, in order this cell implemented fast electrically controlled spatially- inhomogeneous phase light modulation with a depth of ≥π. To form on a screen the large data blocks with information capacity of 10 8 …10 9 pixels and with different geometric configuration a two-dimensional scanner is proposed to use, which is optically coupled to a screen and optical unit of information readout. Possible technical results - increasing the frame rate up to 600 Hz as a minimum, the color gamut expansion, increasing a brightness of images, suppression of the speckle noise, - can be used not only in new devices of information visualization and displaying, but also in systems of data storage and processing and others. |
