Zusammenfassung: | PURPOSE: A shadow mask vibration absorbing structure is provided to prevent deterioration of color purity by effectively reducing the vibration energy transmitted to the shadow mask from an external source. CONSTITUTION: A shadow mask vibration absorbing structure comprises a shadow mask(3) having a plurality of fine holes for passage of electron beams; a frame(5) for supporting the shadow mask, and where a vibration energy is transmitted from an external source; and a skirt portion(20) having an end extended from an effective surface of the shadow mask and the other end coupled to the frame, wherein the skirt portion has a bent section formed between both ends of the skirt portion. Thus, the shadow mask vibration absorbing structure reduces the vibration energy transmitted to the frame by absorbing the vibration energy. The bent section of the skirt portion is shaped as a square C, and includes an outer part coupled to the frame, an inner part extended toward the shadow mask, and a lower end interposed between the outer part and the inner part.
음극선관의 새도마스크 진동흡수 구조체에 관한 것으로, 전자빔이 통과하는 다수의 미세홀을 가진 새도마스크, 외부로부터의 진동에너지가 전달되며 새도마스크를 지지하기 위한 프레임, 그리고 일단은 새도마스크의 유효면으로부터 연장되고 타단은 프레임에 결합되며 일단과 타단 사이에 절곡부를 갖는 스커트부를 포함하여, 외부로부터 프레임으로 전달되는 진동에너지를 흡수하여 외부의 진동 등의 영향이 새도마스크로 전달되는 것을 방지하는 새도마스크 진동흡수 구조체이다. |
