Patent ID: 7067968

Claim:
A cathode ray tube including a color selection apparatus mounted between a phosphor screen and an electron gun installed within a vacuum tube assembly of the cathode ray tube, and one or more support members for supporting the color selection apparatus in the vacuum tube assembly, each of the one or more support members being formed by a spring comprising: a fixed section secured to the color selection apparatus; a locking section connected to the vacuum tube assembly; and a center section formed between the fixed section and the locking section, wherein the fixed section and the center section are separated by a bend at a first folding trace, and the center section and the locking section are separated by a bend at a second folding trace, wherein the spring is only bent between the locking section and the fixed section at the first folding trace and the second folding trace, and wherein if a direction along a width of the spring is X, a direction along a length of the springs is Y, the first folding trace has an angle θ 1 with a straight line drawn on the fixed section along direction X, and the second folding trace has an angle θ 2 with a straight line drawn on the center section along direction X, the angle θ 2 is greater than the angle θ 1.
