    • A cathode ray tube (CRT) having a phosphor screen in which red, green, and blue phosphors are located in a black matrix in a pattern, at the inside of a panel, a low-reflectivity coating layer located at the outside of the panel, the low-reflectivity coating layer having a reflectivity of 2.0% or less near 480˜600 nm, wherein the panel is glass containing neodymium (Nd) in a concentration of 0.1˜1.5 wt % and praseodymium (Pr) in a concentration of 0.1˜0.7 wt %. The CRT has improved brightness and contrast characteristics, and has an enlarged color reproduction range. Also, the problem of the unattractive color of the CRT itself under an external illumination is solved.
    • 一种具有荧光屏的阴极射线管(CRT),其中红色,绿色和蓝色荧光体在图案的黑色矩阵中位于面板的内部,位于面板外侧的低反射率涂层 ,低反射率涂层在480〜600nm附近具有2.0%以下的反射率,其中面板为含有浓度为0.1〜1.5重量%的钕(Nd),浓度为0.1的镨(Pr) 〜0.7重量%。 CRT具有改善的亮度和对比度特性,并具有放大的色彩再现范围。 此外,解决了在外部照明下CRT本身的不吸引人的颜色的问题。
