伊利诺州默尔罗斯的泽尼斯电子公司显象管分部试图依靠新式的彩色显象管使自己能立足于高分辨率电视行业。一般的看法是,显象管的屏幕越大,则电视图象看起来就越舒服。但是,当屏幕很大时,显象管的深度也太大,因此这种情况下必须用直角平面显示屏。泽尼斯公司是美国目前仅存的一家电视机制造商,它提出了自己的生产成本较低的彩色显象管的 The branch of the Zennese Telekom Imaging Division in Mollos, Ill., tried to rely on the new color picture tube to position itself in the high-definition television industry. The general view is that the bigger the screen of the picture tube, the more comfortable the television picture looks. However, when the screen is large, the depth of the picture tube is also too large, so a right-angle flat display screen must be used in this case. The Zenis company is the only remaining television manufacturer in the United States. It has proposed its own color picture tube with a lower production cost.
