    • The invention relates to a large-size image display panel for outdoor use. The image display panel related to the invention has a number of cathode ray tubes which are respectively provided with a plurality of red luminous bodies, green luminous bodies, and blue luminous bodies illuminating themselves by receiving irradiation of electron beams in the inside of the face plate, while each of those cathode ray tubes is also provided with a red filter, a green filter, and a blue filter which are disposed in the outside of the face plate in correspondence with red luminous bodies, green luminous bodies, and blue luminous bodies. Using these filters provided in correspondence with those luminous bodies, electron beams having specific wavelengths from respective luminous bodies are selectively filtered out. As a result, the image display panel related to the invention sufficiently secures the needed luminance intensity of image and reliably generates a satisfactory image exhibiting sharp contrast and high brilliance constantly.
    • 本发明涉及户外使用的大尺寸图像显示面板。 本发明的图像显示面板具有多个阴极射线管,它们分别设置有多个红色发光体,绿色发光体和蓝色发光体,通过接收面板内部的电子束的照射而自身照射 ,而这些阴极射线管中的每一个还设置有与红色发光体,绿色发光体和蓝色发光体对应地配置在面板的外侧的红色滤色器,绿色滤色器和蓝色滤色器。 使用与这些发光体对应地提供的这些滤光片,选择性地滤出来自各个发光体的具有特定波长的电子束。 结果,与本发明相关的图像显示面板充分确保了所需的图像亮度,并可靠地产生持续呈现出明显的对比度和高亮度的令人满意的图像。

    • An implosion protected cathode ray tube which comprises a glass envelope having a faceplate; and a layered protective structure deposited over and positioned frontwardly of the faceplate. The layered protective structure includes a first resin-coated layer held in contact with the faceplate, a hard coated layer for protecting the first resin-coated layer and a second resin-coated layer formed between the first resin-coated layer and the hard coated layer. The first resin-coated layer has a hardness which corresponds to 1H or lower of hardness of drafting pencil lead, and an elongation at breakage within the range of 65 to 85%. The first resin-coated layer also has a break strength of 3.5 kilograms per square millimeter or greater. The hard coated layer has a hardness which corresponds to 5H or higher of hardness of drafting pencil lead, and an elongation of 3% or smaller at breakage. The second resin-coated layer has a hardness generally intermediate between the hardness of the first resin-coated layer and that of the hard coated layer and also an elongation at breakage generally intermediate between the elongation of the first resin-coated layer at breakage and that of the hard coated layer at breakage.
    • 一种内爆保护阴极射线管,其包括具有面板的玻璃外壳; 以及沉积在面板的正上方并位于其上的分层保护结构。 分层保护结构包括与面板保持接触的第一树脂涂层,用于保护第一树脂涂层的硬涂层和形成在第一树脂涂层和硬涂层之间的第二树脂涂层 。 第一树脂涂层的硬度相当于牵伸铅笔的硬度的1H以下,断裂伸长率在65〜85%的范围内。 第一树脂涂层也具有3.5千克/平方毫米或更大的断裂强度。 硬涂层的硬度相当于牵伸铅笔的硬度为5H以上,断裂时的伸长率为3%以下。 第二树脂涂层的硬度通常介于第一树脂涂层的硬度与硬涂层的硬度之间,以及断裂伸长率通常介于第一树脂涂覆层的断裂伸长率之间, 的硬涂层破裂。
