    • In a flat cathode ray tube, a flat glass tube is of three-element structure includes a screen panel integrally provided with skirt portions which are erected from the screen panel along the front end and the opposite side portions thereof continuously, a front panel or a back panel of a sheet-like configuration, and a funnel portion having a neck portion. The screen panel, front panel and funnel portion are combined through frit glasses, and a phosphor screen is formed on the inner surface of the screen panel. An electron gun is disposed within the neck portion, so that an electron beam generated from the electron gun collides with molecules within the flat glass tube to generate negative ions. The negative ions are accelerated and irradiated at the center portion on the skirt portion provided at the front end of the screen panel, whereby the phosphor screen is prevented from being burned by the ions and degradation of the frit glass due to impact of the negative ions is prevented.
    • 在平面阴极射线管中,扁平玻璃管是三元件结构,包括整体设置有从屏幕面板沿着前端竖立的裙部和连续的相对侧部的屏幕面板,前面板或 片状构造的后面板和具有颈部的漏斗部。 屏幕面板,前面板和漏斗部分通过玻璃料玻璃组合,荧光屏形成在屏幕面板的内表面上。 电子枪设置在颈部内,使得从电子枪产生的电子束与平板玻璃管内的分子相撞,产生负离子。 负离子被加速并照射在设置在屏幕面板前端的裙部的中心部分,由此防止荧光屏被离子燃烧并且由于负离子的冲击导致的玻璃料的劣化 被阻止
