从某种程度上讲,显示器的发展史其实就是显像管的发展史。从最早的球面显像管到现在应用最多的平面直角显像管(FST),再到以SONY特丽珑(Trinitron)和三菱钻石珑(Diamondtron)为代表的柱面显像管,显像管的弧度已经越来越小,特丽珑显像管已经实现了垂直方向的零弧度,但在水平和垂直方向仍然没有达到完全的平面。“纯平”显像管(IFT)技术则使传统的CRT显示器终于走上了完全平面的坦途。下面我们分别看看其各自的特点。球面显像管这种显像管的显示平面类似球体的一部分,其水平与垂直方向都有弯曲,带来的结果就是屏幕的边缘会出现图像的失真变形。球面显像管一般是荫罩显像管,尺寸一般为偶数,常见的尺寸为14英寸、16英寸和20英寸。这种显像管在低端领域仍有一定市场。
To some extent, the history of the display is actually the history of the CRT. From the earliest spherical CRTs to the now most widely used flat right angle tubes (FST) to the cylindrical CRTs represented by SONY Trinitron and Diamondtron, the radii of CRTs have become smaller and smaller, Trinitron tubes have achieved zero radians in the vertical direction, but still do not reach full planes in both horizontal and vertical directions. The “flat-screen” tube (IFT) technology has finally brought the traditional CRT monitor to a completely flat surface. Below we look at their respective characteristics. Spherical picture tube This picture tube display plane similar to a part of the sphere, the horizontal and vertical bending, the result is that the edge of the screen will appear distortion of the image. Spherical CRTs are typically shadow mask tubes that are generally even-numbered and are typically 14-inch, 16-inch and 20-inch. This picture tube still has some markets in the low end.
