Development of a new LC rear-projection display with an aspherical mirror projection system

We have developed a new projection system that consists of an aspherical mirror projection system. This system realizes the small depth that cannot be achieved with the conventional rear projection lens. Furthermore, we have developed a new screen that realizes high brightness, good uniformity within the whole image area, a wide viewing angle, and reduction of the ghost image by obtaining the ideal conditions between each blaze angle of the Fresnel screen and the projected rays onto the screen.
