Paper Abstract

A high resolution and luminance projection display, which YAG (yttrium aluminum garnet) projection CRT is employed instead of conventional glass projection CRT, has been developed. The luminance of YAG projection CRT for green is more than 4.5 X 105 cd/m2 at the beam current of 5 mA. A 3-layer rear screen is adopted to obtain wide horizontal and vertical viewing angle without degrading the picture quality. In addition, the development of high resolution projection lens, wide bandwidth video circuit and high precision digital convergence system is realized. A fine quality of picture can be displayed, the horizontal resolution of the projection display is more than 1000 TVL, the peak brightness on the screen is about 1500 cd/m2 (48-in. rear projection display), the contrast ratio is 100. A multi-scanning system can adapt most current picture modes such as NTSC, PAL, SECAM and SVGA display etc.
