对于较小尺寸的彩色电视机,需要尽量简化显象管及其偏转元件,因为这里可节约钱,使携带式电视机比家用电视机便宜得多。因此需要找到新的工艺,以大大简化显象管及其偏转元件。第一种生产成熟的管子是索尼公司的单枪三束管。简化小尺寸彩色显象管的另一种方法是日本东芝公司提出的所谓“RIS”管。这种管子的电子枪不是三角形排列的,而是排成一字形。但是荫罩孔仍为圆形的孔,只是不再按三角形排列,而是直线排列而已。

For smaller size color televisions, the picture tube and its deflection elements need to be as simple as possible because money can be saved here, making the portable televisions much cheaper than home televisions. There is therefore a need to find new processes that greatly simplify the kinescope and its deflection elements. The first production of mature tube is Sony’s single gun three tubes. Another method of simplifying a small size color picture tube is the so-called “RIS” tube proposed by Toshiba of Japan. The electron guns of this tube are not arranged in a triangle, but arranged in a straight line. However, the mask hole is still a circular hole, but no longer arranged by a triangle, but arranged in a straight line.
