尽管竞争对手液晶和发光二极管之类的技术在不断提高,但阴极射线显示管仍然是显示器的支柱。早先的显示器均采用电视显象管,现在大多数已为能满足矩阵显示专门要求的显示管所代替。笔者于1985年完成设计定型的14SG 2Y管(5.5英寸高分辨率显示管)即属此类管型。在14SG2Y管的研制过程中,曾设定三套电子光学系统的实验研究方案。孔径加速极与孔径调制极分别为0.5,0.28毫米;0.320.28毫米;0.28,0.28毫米相配合的发射系统。预聚焦透镜和主聚焦透镜均相同(见图1)。
Although competitors such as liquid crystal and light-emitting diode technology continues to improve, but the cathode ray display tube is still the backbone of the display. Earlier displays were made of TV picture tubes, and most have now been replaced by display tubes that meet the specific requirements of the matrix display. I completed the design and stereotyped in 1985 14SG 2Y tube (5.5-inch high-resolution display tube) that is the type of tube. In the 14SG2Y tube development process, has set three sets of experimental experimental optical electronic systems. Aperture accelerator pole and aperture modulation pole were 0.5,0.28 mm; 0.320.28 mm; 0.28,0.28 mm with the launch system. The prefocus lens and the main focus lens are the same (see Figure 1).
