介绍了研制成功的 YAG投影管及投影显示系统。在阴极电流为 5m A时 ,绿色投影管亮度大于 6.5× 1 0 5cd/ cm2 ,束斑直径在束流为 1 m A时小于 80μm。在 1 2 2 cm背投影机中可重现高质量图象 ,其水平分辨率为 1 0 0 0 TVL,峰值亮度为 1 50 0× 1 0 5cd/ cm2 ,对比度达 1 0 0。
Introduced the successful development of YAG projection tube and projection display system. At a cathode current of 5 m A, the green projection tube brightness is greater than 6.5 × 10 5 cd / cm 2 and the beam spot diameter is less than 80 μm at 1 m A beam. High-quality images can be reproduced in a 122 cm back projector with a horizontal resolution of 100 TVL and a peak brightness of 150 x 105 cm / cm2 with a contrast of 100.
