Lightweight flat screen color cathode ray tube

Abstract:

A color cathode ray tube includes: a panel whose outer surface is substantially flat and whose inner surface has a predetermined curvature; a funnel coupled with the panel; and a deflection yoke installed on an outer circumference of the funnel, wherein the panel has an aspect ratio of about 4:3 and a diagonal length USD of a viewable image size of the panel is less than about 520 mm. The panel satisfies the following relationship: 0.44 ≤ OAH TOR ≤ 0.56 where TOR is distance between an end of the deflection yoke adjacent to the panel and a coupling surface between the panel and the funnel, and where OAH is distance between center of the outer surface of the panel and the coupling surface between the panel and the funnel.

Abstract(Chinese):

彩色阴极射线管包括：外表面基本平坦且内表面具有预定曲率的面板; 与面板连接的漏斗; 以及安装在漏斗的外圆周上的偏转系统，其中所述面板具有约4:3的纵横比，并且面板的可见图像尺寸的对角线长度USD小于约520mm。面板满足以下关系： $0.44<=其中TOR是与面板相邻的偏转线圈的端部与面板和漏斗之间的耦合表面之间的距离，并且其中OAH是面板的外表面的中心与其间的耦合表面之间的距离面板和漏斗。Public/Granted literature US20050067940A1
