Abstract
본 발명은 전화면에서 균등한 크기의 전자빔 스포트를 얻기 위한 칼라 음극선관용 더블 다이나믹 포커싱 전자총에 관한 것이다.The present invention relates to a double dynamic focusing electron gun for color cathode ray tubes for obtaining electron beam spots of uniform size in full screen.
본 발명은, 삼극부를 이루는 캐소오드, 제1,2그리이드와, 유니포텐셜 포커스 렌즈를 이루는 제3,4,5그리이드와, 바이포텐셜 포커스 렌즈를 이루는 제5,6그리이드와, 메인 렌즈를 형성하는 제6,7그리이드를 구비한 칼라 음극선관용 더블 다이나믹 전자총에 있어서, 상기 제4그리이드에는 R,G,B연속된 한 개의 횡장형의 완두껍질형 전자빔 통과공이, 상기 제5그리이드의 입사평면에는 세개의 원형의 전자빔 통과공이, 그 출사평면에는 세개의 종장형의 상기 중원사각형 전자빔 통과공이, 그리고 그출사평면에는 세 개의 원형의 중원사각형 전자빔 통과공이, 그리고 상기 제6그리이드의 입사평면에는 R,G,B연속된 한개의 횡장형의 완두껍질형 전자빔 통과공이, 그출사명면에는 세개의 원형의 전자빔 통과공이, 그리고 상기 제7그리이드의 세 개의 원형의 전자빔 통과공이 형성되고, 상기 제3,5그리이드에는 소정의 포커스 전압이, 상기 제4,6그리이드에는 상기 포커스 전압을 기저전압으로 하며 편향 신호에 동기하여 변조되는 다이나믹 포커스 전압이 인가되는 것을 특징으로 한다.The present invention relates to a cathode, a first grid, a second grid, a third, a fourth grid, a fifth grid, and a fifth, six grid, a bipotential focus lens, and a main lens. A double dynamic electron gun for a color cathode ray tube having a sixth and seventh grid, which is formed in the fourth grid, wherein the fourth grid includes one horizontally-penetrated pea shell electron beam through-hole, which is continuous with R, G and B. Three circular electron beam through-holes are formed in the incidence plane of the id, three long-circuit electron beam through-holes are formed in the exit plane, and three circular medium-square electron beam through-holes are shown in the emission plane and the sixth grid. In the plane of incidence of R, G, B, one continuous row-shaped pea-penetrated electron beam through-hole, its exit surface has three circular electron beam through-holes, and the seventh grid has three circular electron-beam through-holes. A hole is formed, and a dynamic focus voltage modulated in synchronization with a deflection signal is applied to the third and fifth grids, and a predetermined focus voltage is applied to the fourth and sixth grids. It is done.
