1 环保型彩电 传统的彩电使用的CRT彩色显象管工作在2万5千多伏的阳极高压下,会激发出微量的X射线,当人体离彩电过近就会受到X射线的影响,并且彩电的画面也会闪烁,从而影响人的视力。 环保型彩电采用了新型显象管和新技术,其内藏式电子枪中设置了X射线吸收电路,从而使其对外有害辐射降低为零。同时,该类显象管也采用了新型的偏转,并在阴罩栅与玻璃壳之间填充了宽色彩再现 An environment-friendly color TV CRT color picture tube used in the traditional color TV tube work under an anodic pressure of 25,000 volts, will stimulate a trace of X-ray, when the human body is too close to the color TV will be X-ray effects, and TV screen will flicker, thus affecting people’s eyesight. Environmentally friendly color TV with a new type of CRT and new technology, its built-in electron gun X-ray absorption circuit is set, so that its harmful external radiation to zero. At the same time, this type of tube also uses a new type of deflection, and between the shadow mask and glass filled with a wide color reproduction
