Patent number: 7061172Abstract: A flat color cathode ray tube having excellent doming quality is obtained by improving the structure of a flat panel and by using a shadow mask made of AK (aluminum-killed) material. According to the cathode ray tube, an outer surface of a panel used for the cathode ray tube is substantially flat, and an inner surface thereof has a curvature, and a transmittance ratio of ending portion of an effective surface to central portion of the panel is in the range of 0.4 to 0.6, and the radius of diagonal curvature (Rd) of the inner surface of the panel is in the range of 1.29R to 4.35R (R=1.767×diagonal length of effective surface), and a shadow mask is made of AK material. The cathode ray tube embodying the principles of the present invention is very advantageous in that it has a price as low as half the price of the conventional cathode ray tube, yet its panel uses a shadow mask made of AK material which has a doming quality equivalent to that of a shadow mask made of Invar material.Type: GrantFiled: October 8, 2002Date of Patent: June 13, 2006Assignee: LG.Philips Displays Korea Co., Ltd.Inventor: Sung Han Jung
