본 발명은 컬러모니터(Color Display Tube)에 관한 것으로, 더욱 상세하게는 섀도우마스크와 형광면상의 형광체도트형상을 정육각형으로 형성하여 동일한 트랙피치(Track Picth)를 가지면서 도트상의 빛이 투과하는 면적을 크게 하므로써 높은 해상도를 유지함과 동시에 휘도를 향상시킬 수 있도록 한 컬러모니터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color display tube, and more particularly, to form a shadow dot and a phosphor dot shape on a fluorescent surface in a regular hexagon, so as to have a large area where light of a dot is transmitted while having the same track pitch. Therefore, the present invention relates to a color monitor capable of improving brightness while maintaining high resolution.

일반적으로, 컬러모니터(10)는 제1도에 도시된 바와 같이, 네트(Neck)(12)부분에 적(Red), 녹색(Green), 청(Blue)색의 전자빔을 주사하는 3개의 전자총(14)이 설치되고, 패널(16)부분에는 그 내측의 형광면(18)으로 부터 약 10mm 떨어진 위치에 색선별 기능을 갖는 섀도우마스크(20)가 설치된 구조로 이루어져 있는바, 이같은 칼라브라운관(10)에서는 제2도에 도시된 바와 같이, 상기 각 전자총(14)에서 주사된 적, 녹, 청의 세가지 전자빔이 상기 섀도우마스크(20)에 바르게 배열된 미세한 빔조사공(22)을 통하여 패널(16)의 내측면에 도포된 적, 녹, 청색의 형광체도트(24)에 정확히 충돌되도록 하여 발광시키므로써 컬러영상을 생성시키도록 되어 있다.In general, the color monitor 10 has three electron guns that scan red, green, and blue electron beams on the neck 12, as shown in FIG. 14 is provided, and the panel 16 has a structure in which a shadow mask 20 having a color discrimination function is provided at a position about 10 mm away from the inner fluorescent surface 18 thereof. In FIG. 2, as shown in FIG. 2, three electron beams of red, green, and blue that are scanned by the electron guns 14 are disposed on the panel 16 through the fine beam irradiating holes 22 correctly arranged in the shadow mask 20. The color image is generated by emitting light by accurately colliding with the red, green, and blue phosphor dots 24 coated on the inner surface of the C.

이와 같은 컬러모니터의 해상도는 형광체도트의 중심점에서 동일색을 갖는 최인접 형광체 도트까지의 거리인 트랙피치(Track Picth)에 의해 정해지며, 이같은 형광체의 형상은 섀도우마스크 형상에 의해 텔레비전용 브라운관에 적용되는 슬릿(Slit)형과 제3도에 도시된 바와 같은 고정세 모니터용 브라운관에 적용되는 도트형으로 구분된다.The resolution of the color monitor is determined by Track Picth, which is the distance from the center point of the phosphor dot to the nearest phosphor dot having the same color, and the shape of the phosphor is applied to the CRT tube by the shadow mask shape. It is divided into a slit type and a dot type applied to a high definition monitor CRT as shown in FIG.

따라서, 고정세 모니터용 컬러브라운관은 슬릿형보다 도트형을 사용하여 해상도를 향상시키고 있지만 텔레비전용 브라운관에 적용되는 형광체 도트형상을 슬릿형으로부터 도트형으로 변화시키면 트랙피치가 감소됨에 따라 해상도를 높일 수는 있으나, 이 경우 전자빔이 통과하는 섀도우마스크의 저공위 면적이 작아지기 때문에 좁은 도트면적에 전자빔을 포커싱(Focussing)하기 위해서는 전자빔의 량이 감소되므로 휘도가 저하된다는 문제점이 있었다.Therefore, the color CRT for high-definition monitors uses a dot type rather than a slit type to improve the resolution. However, if the phosphor dot shape applied to the CRT for television is changed from a slit type to a dot type, the resolution can be increased as the track pitch decreases. However, in this case, since the low airspace area of the shadow mask through which the electron beam passes is small, in order to focus the electron beam on a narrow dot area, the amount of the electron beam is reduced, thereby reducing the luminance.

이에 따라, 최근에는 고정세 컬러브라운관에서 휘도를 향상시키기 위하여 전자총을 개량하려는 시도가 있으나, 이 경우 개량되는 전자총의 특성에 맞추어 다른 부품도 개량해야 되기 때문에 비용이 많은 소요된다는 문제점이 있었다.Accordingly, in recent years, there has been an attempt to improve the electron gun in order to improve the brightness in a high-definition color CRT, but in this case, there is a problem in that it takes a lot of cost because other components have to be improved according to the characteristics of the improved electron gun.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 컬러브라운관에 적용되는 섀도우마스크의 도트의 형상과, 패널내면에 형성되는 형광체도트의 형상을 반지름(R)을 갖는 원에 외접하는 정육각형으로 형성하여 동일한 트랙피치를 갖게 하고 도트의 면적을 크게하므로써 고정세를 유지하면서 휘도를 향상시킬 수 있도록 한 새로운 컬러브라운관을 제공하고자 하는데 목적이 있다.The present invention is to solve the conventional problems as described above, the shape of the dot of the shadow mask applied to the color brown tube and the shape of the phosphor dot formed on the inner surface of the panel in a regular hexagon to circumscribe the circle with a radius (R) It is an object of the present invention to provide a new color CRT which can improve luminance while maintaining high definition by forming the same track pitch and increasing the dot area.

이하, 첨부된 도면에 의하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

본 발명은 제4도에 도시된 바와 같이, 컬러브라운관(10)에 적용되는 섀도우마스크(20)와 패널(18)내면에 도포되는 형광체도트(24)의 형상을 일정한 반지름을 갖는 원에 외접하는 정육각형으로 형성하여 된 특징을 갖는다.As shown in FIG. 4, the shape of the shadow mask 20 applied to the color brown tube 10 and the phosphor dot 24 applied to the inner surface of the panel 18 is circumscribed to a circle having a constant radius. It is characterized by being formed into a regular hexagon.

이와 같은 본 발명의 작용은 다음과 같다.Such action of the present invention is as follows.

제5도에 도시된 바와 같이, 본 발명에 따라 섀도우마스크(20)의 도트 형상을 반지름 R을 가지는 원형상으로부터 그 원에 외접하는 정육각형상으로 변화를 시키면, 이 정육각형상과 종래 원형 도트와의 면적은 다음과 같다.As shown in FIG. 5, when the dot shape of the shadow mask 20 is changed from a circular shape having a radius R to a regular hexagon circumscribed to the circle, according to the present invention, The area is as follows.

이와 같은 본 발명의 정육각형도트와 종래의 원형도트와의 면적차 C는,The area difference C between the regular hexagonal dot of the present invention and the conventional circular dot is

이고, 종래 원형도트의 면적에 대한 본 발명에 따른 정육각형도트의 면적의 증가율은The increase rate of the area of the regular hexagonal dot according to the present invention with respect to the area of the conventional circular dot is

이 된다.Becomes

이에 따라서 본 발명에 따른 정육각형도트를 적용하는 경우 종래의 원형도트와 동일한 트랙피치를 갖기 때문에 고정세화를 유지할 수 있고, 면적이 종래의 것보다 10% 이상 증가됨에 따라 빛이 투과하는 량도 종래에 비해 10% 이상 증가되므로 휘도가 향상된다는 효과가 있다.Accordingly, when the regular hexagonal dot according to the present invention has the same track pitch as the conventional circular dot, it is possible to maintain a high definition, and the amount of light transmitted as the area is increased by 10% or more than the conventional one Compared to 10% or more, the brightness is improved.

또한, 일반적으로 새로운 브라운관을 개발하는 경우 트랙피치를 미리 설정하고, 그에 따른 섀도우마스크의 도트크기 및 전자총과 패널사이의 거리등 제반변수를 결정하여야 되나, 본 발명의 경우에는 이러한 과정을 거치지 않고, 단순히 기존의 섀도우마스크의 도트형상을 정육각형상으로 바꾸어주기만 하면 되므로 최적 컬러브라운관설계를 거치지 않고서도 쉽게 제조가 가능하다는 효과가 있다.In general, when developing a new CRT, the track pitch must be set in advance, and the shadow variables, such as the dot size and the distance between the electron gun and the panel, should be determined. Simply change the dot shape of the existing shadow mask into a regular hexagon shape, so that it can be easily manufactured without going through the optimal color CRT design.
