    • There is provided a cathode-ray tube including an envelope having a neck, a funnel and a panel fused to the funnel by using frit glass, the outside of the panel being near flat, the inside of the panel having a predetermined curvature, in which 1.7≦T2/T1≦2.3 when T1 is the thickness of the center of the panel and T2 is the thickness of the diagonal corner of the panel, and a panel inside tensile stress at the fused portion of the panel and funnel is less than −1.3876x+128.24 (Kgf/cm2) when the size of the effective picture area of the cathode-ray tube is x(unit: cm). The panel inside tensile stress at the fused portion of the panel and funnel is maintained below a predetermined value to mitigate breakage inside the furnaces that occurs when the cathode-ray tube having the panel whose outside is near flat and whose inside has a predetermined curvature is reproduced, thereby improving the salvage rate.
    • 提供了一种阴极射线管,其包括具有颈部,漏斗和通过使用熔结玻璃熔合到漏斗的面板的外壳,面板的外部接近平坦,面板的内部具有预定的曲率,其中 当T1是面板中心的厚度,T2是面板对角线的角度时,1.7 <= T2 / T1 <= 2.3,面板和漏斗的熔断部分的拉伸应力面板较小 当阴极射线管的有效图像面积的大小为x(单位:cm)时,比-1.3876x + 128.24(Kgf / cm 2)大。 在面板和漏斗的熔融部分处的拉伸应力内的面板保持在预定值以下,以减轻当具有外部接近平板且其内部具有预定曲率的面板的阴极射线管在炉内时的破裂 转载,从而提高打捞费率。
