Abstract
A panel structure for a Braun tube is described satisfying the following conditions:Rdo/(USDd×1.767)≧35 and 0.7≦(MMLHd/OAH)≦0.9,wherein Rdo denotes a radius of curvature of a panel in a cathode ray tube, USDd denotes a length of the effective surface part in a diagonal direction, MMLHd denotes a height from the seal edge line to the mold match line, and OAH denotes a total height of a panel, thereby suppressing implosion that occurs during or after fabrication of a Braun panel and securing an implosion proof characteristic.
