    • A structure of a slot feature for a shadow mask in which, on the assumption that the width at the point of ½ in a vertical direction in the feature of slots of the shadow mask is ‘Sw’, horizontal distances from a virtual vertical line passing an apex of a concave portion of a slot at a marginal portion to a protrusion portion formed at both upper and lower sides on the basis of the width Sw line are ‘M’ and ‘N’, and angles inclined in the direction of the protrusion portion from the virtual straight line passing the apex of the curved protrusion portion formed at the opposite side of the concave portion are ‘P’ and ‘Q’, there are at least one and more mask slot satisfying a formula of M>0, N>0, P>0°, Q>0°. The shape of electron beams by positions on the screen are identical to each other, and the shape of electron beam at the left and right sides of marginal portion can be maintained in a straight line in the vertical direction. Accordingly, a purity margin of the electron beam can be increased and brightness characteristics can be improved, and thus, a quality of color reproduction can be heightened.
    • 用于荫罩的槽特征的结构,其中,假设荫罩的槽的特征中的垂直方向上的1/2处的宽度为“Sw”,则距虚拟垂直线通过的水平距离 基于宽度Sw线,形成在上下两侧的突出部分的边缘部分的槽的凹部的顶点是“M”和“N”,并且在突起方向上倾斜的角度 通过形成在凹部的相对侧的弯曲突出部的顶点的虚拟直线的部分为“P”和“Q”,至少一个以上的掩模槽满足公式M> 0,N > 0,P> 0°,Q> 0°。 通过屏幕上的位置的电子束的形状彼此相同,并且边缘部分的左侧和右侧的电子束的形状可以在垂直方向上保持为直线。 因此,能够提高电子束的纯度裕度,提高亮度特性,能够提高色彩再现的品质。

    • Flat CRT panel including a substantially flat outside surface, and an inside surface of a fixed curvature, wherein the inside surface of the panel is formed to meet a condition of {(Rh+Rv)/2}×Rd being in the range of 8.0-10.3, where “Rd” denotes a representative diagonal sectional radius of curvature, “Rh” denotes a representative long-axis sectional radius of curvature, and “Rv” represents a representative short-axis sectional radius of curvature when an effective screen size of the panel is greater than 25″, thereby reducing thermal breakage, and permitting fabrication of lighter panel.
    • 扁平CRT面板包括基本上平坦的外表面和固定曲率的内表面,其中面板的内表面形成为满足{(Rh + Rv)/ 2}×Rd的条件为8.0- 10.3,其中“Rd”表示代表性的对角截面曲率半径,“Rh”表示代表性的长轴截面曲率半径,“Rv”表示当有效屏幕尺寸为 面板大于25“,从而减少热断裂,并允许制造更轻的面板。
