一、采用天线式掺氮消气剂(器)带来的问题 近年来,彩显管向高亮度、大屏幕、小管颈方向发展。直观式电视机的屏幕尺寸为26英寸,个别的已达32或60英寸。尤其大屏幕投影电视机,其放映图象的尺寸已达50～120英寸或更大。大的图象显示,不仅可供多人同时观看,而且映出的图象清晰,逼真动人,富有魅力,具有一定的立体感和临场感。但提高图象放大率,得到明亮的图象,势必要通过较大的电流并导致阳极电压迅速升高。目前从11～12KV,升高到18～20KV以
First, the use of antenna-type nitrogen nitrogen getter (device) brings problems In recent years, color display tube to high brightness, large screen, small tube neck direction. Intuitive televisions have a screen size of 26 inches and individual ones have reached 32 or 60 inches. In particular, large-screen projection TV sets have shown that the size of the images has reached 50 to 120 inches or more. Large image display, not only for many people to watch at the same time, but also reflect the image clear, vivid and attractive, full of charm, with a certain sense of three-dimensional and presence. However, to increase the image magnification and obtain a bright image, it is bound to pass a large current and cause the anode voltage to rise rapidly. Currently from 11 ~ 12KV, increased to 18 ~ 20KV
