본 고안은 칼라음극선관용 전자총에 관한 것으로, 보다 상세하게는 R.G.B전자빔이 통과하는 전자빔통과공의 내측 일정부위를 굴곡시켜, R.B.G전자빔 간에 전계의 간섭을 방지하고, 아울러 전계분포의 곡률을 완화시켜 해상도 및 포커스를 향상시키도록 한 칼라음극선관용 전자총에 관한 것이다.The present invention relates to an electron gun for a color cathode ray tube, and more particularly, to bend an inner portion of an electron beam through hole through which an RGB electron beam passes, to prevent interference of an electric field between RBG electron beams, and to reduce curvature of an electric field distribution. And an electron gun for a color cathode ray tube to improve focus.
첨부된 예시도면 도 1은 종래의 칼라음극선관용 전자총을 나타낸 도면인 바, 먼저 전자총(10)은 통상 3개의 캐소우드(12)가 설치되어 있고, 이 캐소우드(12) 앞에는 제 1∼5전극(14,16,18,20,22)이 순차적으로 배치되어 있다.1 is a view illustrating a conventional electron gun for a color cathode ray tube. First, the electron gun 10 is generally provided with three cathodes 12, and the cathodes 12 are first to fifth electrodes. 14, 16, 18, 20, and 22 are sequentially arranged.
그리고, 상기 캐소우드(12)를 일정한 온도로 가열시키게 되면, R.G.B전자빔(26,26,28)이 방출되어 제 1∼6전극(14,16,18,20,22,24)을 통과하게 되는데, 먼저 제 1,2전극(14,16)에서는 R.G.B전자빔(26,28,30)의 메인렌즈 입사각 및 입사높이를 조절하게 되며, 제 6전극(24)은 전자빔을 가속시켜 패널 내면에 도달되도록 하는 역할을 하게 되는 것이다.When the cathode 12 is heated to a constant temperature, the RGB electron beams 26, 26, 28 are emitted to pass through the first to sixth electrodes 14, 16, 18, 20, 22, and 24. First, the first and second electrodes 14 and 16 adjust the incidence angle and the incidence height of the main lens of the RGB electron beams 26, 28 and 30, and the sixth electrode 24 accelerates the electron beam to reach the inner surface of the panel.

As shown in FIG. 2, the curvature of the electric field distribution 36 is increased to increase the spherical aberration of the electrostatic lens, and accordingly, the RGB electron beams 26 and 28 passing through the electron beam through hole 32 are formed. 30) interference between the electric field distributions 36 is generated, and thus the focus state of the screen becomes unstable, and there is a problem that the resolution is lowered.

Only different points from the above will be described.
첨부된 예시도면 도 3을 참조하면, 먼저 전자총(10)은 통상 3개의 캐소우드(12)가 설치되어 있고, 이 캐소우드(12) 앞에는 제 1∼6전극(14,16,18,20,22,24)이 순차적으로 배치되어 있다.Referring to FIG. 3, first, the electron gun 10 is generally provided with three cathodes 12, and the first to sixth electrodes 14, 16, 18, 20, 22 and 24 are sequentially arranged.
여기서, 본 고안은 제 5전극(22) 내부에 형성된 전자빔통과공(40) 굴곡부(42)의 일끝을 내측으로 굴곡시킨 상태에서 R.G.B전자빔(26,28,30)이 통과되도록 설치되어 있다.Here, the present invention is installed so that the R.G.B electron beams 26, 28, 30 pass in a state in which one end of the bent portion 42 of the electron beam passing hole 40 formed in the fifth electrode 22 is bent inward.
한편, 도 4는 본 고안의 다른 실시예를 나타낸 것으로, 먼저, R.G.B전자빔(26,28,30)이 통과되도록 전자빔통과공(50)을 형성한 보조전극(52)을 제작하여 제 5전극(22)의 내부에 형성된 각 전자빔통과공(54)과 일치시킨 상태로 밀착.고정되도록 구성되어 있다.Meanwhile, FIG. 4 shows another embodiment of the present invention. First, a fifth electrode (5) is manufactured by forming an auxiliary electrode 52 having an electron beam through hole 50 to pass RGB electron beams 26, 28, and 30. It is configured to be in close contact with and fixed in a state coinciding with each of the electron beam through holes 54 formed in the inside of the 22).
상기와 같이 구성된 본 고안은 첨부된 예시도면 도 3에 도시된 바와 같이 먼저,The present invention configured as described above is first shown in Figure 3 attached to the accompanying drawings,
전자총(10) 제 5전극(22)의 전자빔통과공(40)으로 R.G.B전자빔(26,28,30)이 통과될 경우, 상기 각 전자빔통과공(26,28,30)은 이와 일체로 형성된 굴곡부(42)의 일끝부위가 내측으로 굴곡.형성되어 있어서, 각 전자빔통과공(40) 간에 전계분포(44)의 곡률을 적게시켜 정전렌즈의 구면수차를 적게함으로써, 상기 전자빔통과공(40)을 통과하는 R.G.B전자빔(26,28,30)간에 전계간섭을 방지하게 되어, 결국 R.G.B전자빔(26,28,30)의 안정화로 해상도를 향상하게 하는 것이다.When the RGB electron beams 26, 28, 30 pass through the electron beam passing holes 40 of the fifth electrode 22 of the electron gun 10, each of the electron beam passing holes 26, 28, 30 has a bent portion formed integrally therewith. One end portion of (42) is bent inward. The electron beam through hole 40 is formed by reducing the curvature of the electric field distribution 44 between the electron beam through holes 40 to reduce the spherical aberration of the electrostatic lens. This prevents electric field interference between the passing RGB electron beams 26, 28, and 30, thereby improving the resolution by stabilizing the RGB electron beams 26, 28, and 30.

The electron beam through hole 50 of the auxiliary electrode 52 and the fifth electrode 22 are inserted and fixed in a state coinciding with the respective electron beam through holes 54 formed in the five electrodes 22. The curvature of the electric field distribution 56 between the electron beam passing holes 54 is alleviated, and the influence of mutual interference between the RGB electron beams 26, 28, and 30 is reduced, thereby stabilizing the RGB electron beams 26, 28, and 30 passing therethrough. As a result, the resolution is improved.
