日本松下电器无线电研究所对二年半前研制的场致发光显示装置Ⅰ号机作了改进,制成了新型Ⅱ号机。该机的性能和扫描技术有很大提高。其亮度为10呎-朗伯,对比度为10:1～20:1,灰度为8级,分解力为150线。而Ⅰ号机则分别为1呎-朗伯,3:1～5:1,4～5 Japan’s Matsushita Electric Institute of radio on the two years and a half ago developed electroluminescent display unit No. I made improvements made to a new type II machine. The aircraft’s performance and scanning technology has greatly improved. Its brightness is 10 feet - Lambert, the contrast ratio is 10: 1 ~ 20: 1, the grayscale is 8, the decomposition force is 150 lines. On the other hand, I was 1 ft - Lambert, 3: 1 ~ 5: 1, 4 ~ 5 respectively
