前言我厂显象管的荧光屏发光亮度曾一度停留在较低水平上,14英寸显象管同引进线生产管相比,屏中心亮度低24％,17英寸显象管同进口管(如东芝显象管)相比,屏中心亮度低15％。在国产原料和现有设备基础上,我们重新在涂屏、涂膜、铝化上下功夫,使荧光屏发光亮度达到了进口管和引进生产管的同等水平,17英寸显象管屏中心亮度达到121尼特,14英寸显象管屏中心亮度达到140尼特(见表1)。 Foreword Our factory CRT screen luminescence brightness once stayed at a low level, 14-inch CRT with the introduction of the production line compared to 24% lower screen brightness, 17-inch CRT with the importation of tubes (such as Toshiba CRT) compared to 15% lower screen center brightness. Based on the domestic raw materials and existing equipment, we re-painted screen, coating, aluminum work hard to make the luminescent screen brightness reached the same level of imported tubes and the introduction of production tubes, 17-inch CRT screen brightness of 121 Nite, 14-inch CRT screen center brightness reached 140 nits (see Table 1).
