Development of Laser TV that Uses Visible Laser Light Source

Abstract

We have successfully developed a new category of television, a laser TV, which uses a visible-ray laser. Our new laser TV has a color gamut that is approximately twice that of conventional liquid crystal TVs owing to the monochromaticity of the laser, which is one of the specifi c features of the laser system. The high efficiency of laser energy conversion, together with the optical systems optimized to our developed laser, managed to reduce the power consumption of the new laser TV to a level less than a half that of a liquid crystal television of the same size. On the other hand, the high coherency of the laser causes scintillation, and this degrades the quality of pictures. To solve this problem, we have succeeded in developing a new moving screen, which greatly contributes to the production of a laser TV system with high image quality.
