This is the oldest of over one thousand domestic television sets in our collection - and its still in working

It could only be used to receive programmes in and around London , the site of the only transmitter at that time. It also has a radio set in the top so this makes it one of the

5、earliest home entertainment centres. If you had bought this set in 1939 it would have cost as much as a small car. 8(1949 - 7 inch)This is one of the rarest 7 inch electrostatic sets. Like the Temple TV-1776, it has a built in magnifying lens, which is made of plastic and filled with mineral oil. Th

You can work out the price of the 55-inch version.12CRT显示器13vCRT的缺点：从大屏幕显示方面来讲，100cm以上的CRT质量要超过100kg，体积大，搬动困难，不能适应现代家庭对高清晰度电视（HDTV）和现代战争对大屏幕显示器的要求。在这种情况下平板显示技术应运面生，而且获得了迅速发展。平板显示在国际上尚没有严格的定义，一般是指显示器的厚度小于显示屏幕对角线尺寸四分之一的显示技术。这种显示器厚度较薄，看上去就像一块平板，平板显示因此而得名。14液晶L

8、CD平板显示器等离子体PDP平板显示器15v平板显示的种类较多，按显示媒质和工作原理分：有液晶显示（LCD）、等离子体显示（PDP）、电致发光显示（ELD）等。从目前的技术发展水平看，CRT每个像素的性能价格比要比其他显示器件高得多，因此它不会在短期内消失。LCD主要在微型和中小屏幕占优势。PDP由于制作工艺相对简单，易于制作大屏幕，是发展多媒体显示，壁挂式电视和HDTV最有竞争力的显示技术。随着RGB激光技术的迅速发展，激光电视技术已向我们靠近，它具有色域宽，色彩更逼真，且成像面积大的特点，是公众媒体及娱乐场所多媒体显示的又一发展方向。本章介绍几种主要的显示技术。1617Thats all.
