Abstract
A Braun tube including a shadow mask, a panel for supporting the shadow mask, stud pins fitted between the shadow mask and the panel, and a frame of substantially rectangular form having a long side with a height in a range of (0.8-0.9)×(a height from a center of the stud pin to a central point of an inside surface of the panel), and a short side and a corner side each with a height in a range of (0.7-0.85)×(the height of the long side), thereby making the Braun tube stable from influences from doming, howling, and geomagnetism by optimizing respective heights of the frame to satisfy various requirements for the Braun tube at the same time when an overall size of the frame is increased, and permitting convenience of design.
