TW436842B - Shadow mask positioning structure of color cathode ray and method of the same - Google Patents

Abstract

The present invention is a shadow mask positioning structure of color cathode ray and method of the same. There is disposed securely at least a shadow mask positioning device at the corresponding position of any side of the glass envelope of the cathode ray tube and the peripheral frame of a shadow mask, and the material of the positioning device is the same with the shadow mask. One end of the device is fixed directly on the frame of the shadow mask along the vertical direction, and the other end thereof is fixed inside the glass envelope along the vertical direction by the convex cylinder. The section between two fixed ends is bent into two reversely symmetric first middle part and second middle part, so that the positioning device can compensate the heat expansion generated by itself when the RGB electron beam of the color cathode ray tube performs the image developing scan and thereby heats the shadow mask. The shadow mask can therefore keep an expectable position and direction to avoid the occurrence of rotational shift of the shadow mask centered at the center position of the cathode ray tube effectively, which ensures that the aperture of the shadow mask can make the RGB electron beam be projected accurately onto the phosphor deposit at the corresponding position inside the display screen and enhances the color purity of the video image effectively.

The mask positioning structure within the scope of patent application, wherein the positioning element can be bent between the two fixed ends to form at least two t-sections which are mutually symmetrical. 6. The shadow mask positioning structure of the color cathode ray tube according to item 1, 2, 3, 4 or 5 of the patent application scope, wherein the material of the positioning element is the same as the shadow mask. 7. The shadow mask positioning structure of a color cathode ray tube as described in item 4 of the scope of the patent application, wherein the positioning element is connected between the two fixed ends by welding with two first and second oppositely symmetrical first middle portions unit. 8. A method for positioning a shadow mask of a color cathode ray tube, the positioning method is to vertically fix one or more positioning elements made of a metal material between a shadow mask frame of the color cathode ray tube and a glass envelope body At the corresponding position on any side, the three-color electron beam of the color cathode-ray tube is scanned for development, and when the shadow mask is heated, the positioning element can compensate for the thermal expansion generated by itself, so that the shadow mask Keep in a predictable position and direction. 9. The shadow mask positioning method for a color cathode ray tube as described in item 8 of the scope of the patent application, wherein the positioning element is bendable between the two fixed ends into two or more middle portions that are mutually symmetrical. 10. The shadow mask positioning method for a color cathode ray tube according to item 8 or 9 of the scope of patent application, wherein the material of the positioning element is the same as the shadow mask. 第13頁Page 13
