显像管是大屏幕彩电最重要的部件。世界驰名的显像管有素尼特丽珑,松下碧明,东芝晶丽……等,其性能、特点各有不同。一、平面直角(方角)显像管屏幕从表面形状,展扩来看多为球形、柱形、多曲面形管等几何形状,都有一个参数——曲率半径 R,量纲是公尺(米、m)。曲率半径愈大,屏幕愈平,如 R2.5(曲率半径2.5公尺)的屏幕,就比 R1.5(曲率半径
Picture tube is the most important part of the big screen color TV. Well known in the world have a picture tube Nepalese Longines, Panasonic Bi Ming, Toshiba Jingli ...... and so on, its performance, different characteristics. First, the plane right angle (square) CRT screen from the surface shape, expansion to see more spherical, cylindrical, curved surface geometry and other geometric shapes, there is a parameter - radius of curvature R, the metric is meters (meters, m). The larger the radius of curvature, the more flat the screen, as R2.5 (2.5m radius of curvature) of the screen, than R1.5 (radius of curvature
