PAGE 2 PAGE 27 摘要 CRT电视机的结构是一根真空管,里面有一个或多个电子枪,电子枪射出电子束,电子束射到真空管前屏幕表面的内侧时,屏幕内侧的发光涂料受到电子束的击打而发光产生图像的技术。是电视中比较古老的一类。目前很新型显像技术都是在这个传统技术的基础上发展出来的。电视被称为二十世纪最伟大的发明之一,人类的生活因为电视而发生了深刻的变化。电视成为人们充实自己、了解世界的窗口,人们足不出户,便尽知天下事。作为当今世界最强有力的传媒之一,电视在人们的生活中不可或缺。即使是互联网等数字技术如此发达的今天,电视在传递信息、传播文化、大众娱乐等方面,仍然有不可替代的地位。 通过对5.5英寸CRT黑白电视机的组装与调试不仅可以让我们对电视显像技术有一定的了解,更重要的是可以提高我们的实际动手能力,对我们学习该类电器的组装调试与检修都有很重要的意义。 本文是对CRT黑白电视机元件的识别、组装、焊接、后期调试,对可能遇见的故障与解除故障的方法进行详细地说明与实施方案。 [关键字]:CRT;电视机;偏转线圈 ABSTRACT The luminous paint by the electron beam hitting the inside of the screen while the light-emitting structure of the CRT TV is a vacuum tube, there are one or more electron gun, electron gun injection electron beam, electron beam hitting the vacuum tube before the inside of the screen surface,generated image technology. The old TV. At present a new imaging technology on the basis of this traditional technology developed. TV is known as the greatest inventions of the twentieth century, human life because television has undergone a profound change.
