본 발명은 평판디스플레이장치의 커버그라스에 관한 것으로서, 더욱 상세하게는 평판디스플레이의 외관을 형성하는 커버그라스의 제조를 모따기공정없이 평판유리의 외곽을 한 번의 공정으로 절곡하여 생산성을 향상하면서 미려한 외관을 얻을 수 있도록 하는 평판디스플레이의 커버그라스에 관한 것이다.The present invention relates to a cover glass of a flat panel display device, and more particularly, to manufacture a cover glass to form the appearance of a flat panel display by bending the outer surface of the flat glass in one step without a chamfering process to improve productivity while improving the beautiful appearance. It relates to a cover glass of a flat panel display that can be obtained.

종래 평판디스플레이장치에 적용되는 커버그라스는 도 1에서와 같이 평판디스프레이(1)의 전면과 외측면에 단익편상의 유리판(2)(2a)(2b)을 배치한 후 몰딩제로 몰딩처리하여 구성하고 있다. 이러한 유리판(2)(2a)(2b)은 규격이 다른 여러 개의 단위익편으로 절단한 후 평판디스플레이기판(1)의 전면에 배치되는 전면유리판(2) 둘레로 폭이 좁고 긴 단위의 유리판(2a)(2b)을 배치하기 때문에 배치작업에 세밀한 조정이 필요함과 동시에 접촉부위의 틈새를 몰딩제로 몰딩작업하기에는 작업의 불편과 공정의 복잡함으로 원가절감을 이루지 못하는 문제가 있었다.The cover glass applied to the conventional flat panel display device is configured by disposing a single blade piece glass plate (2) (2a) (2b) on the front and the outer surface of the flat panel display (1) as shown in FIG. have. The glass plates 2, 2a, and 2b are cut into several unit blade pieces having different specifications, and then the glass plates 2a of narrow and long units are formed around the front glass plate 2 disposed on the front surface of the flat panel display substrate 1. (2b) has to be finely adjusted in the batch operation and at the same time there is a problem that the cost reduction due to the inconvenience of the operation and the complexity of the process for molding the gap of the contact portion with the molding agent.

이와 같은 문제점을 해결하기 위해서, 커버그라스의 모서리를 모따기 한 다음에 절곡하는 기술이 본원 출원인에 의하여 특허등록출원 제98-53608호(출원일; 1998. 12. 08.)를 출원한 바 있다.In order to solve such a problem, a technique for chamfering and then bending a covergrass has been filed by the applicant of the patent application No. 98-53608 (filed date: Dec. 08. 1998).

그러나 상기한 종래의 커버그라스는 원판유리의 사각모서리를 각각 모따기 한다음에 열처리하고 이어서 밴딩한 후 모서리부위를 몰딩하여 평판디스플레이장치의 커버그라스를 형성하고 있기 때문에 각모서리의 모따기 공정과 밴딩 후 몰딩하여야 하므로 작업공정의 번거러움과 미관이 미려치 못하는 문제점이 있었다.However, the conventional cover glass is heat treated after chamfering the corner corners of the original glass and then banded, and then the corners are formed to form the cover glass of the flat panel display device. There was a problem that the cumbersome and aesthetics of the work process were not insignificant.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 평판디스플레이의 외관을 형성하는 커버그라스의 제조를 보다 빠른 시간에 자동적이며 간단하고도 용이하게 성형하여서 평판디스플레이에 간편하게 접착하므로 작업의 공정을 줄임과 동시에 생산원가를 저렴하게 할 수 있게 하고 미려한 외관을 이루게 하는 평판디스플레이의 커버그라스를 제공하는데 있다.The present invention has been made in order to solve the above problems, the production of the cover glass to form the appearance of the flat panel display in a faster time automatically and simply and easily molded easily adhered to the flat panel display process of work It is to provide a cover glass of flat panel display that can reduce production cost and at the same time reduce the cost of production.

상기한 목적으로 달성하기 의해 본 발명에 의한 평판디스플레이의 커버그라스는, 평판디스플레이장치의 전면에 기밀을 유지하는 커버그라스에 있어서,The cover glass of the flat panel display according to the present invention by achieving the above object, in the cover glass to maintain the airtight on the front surface of the flat panel display device,

상기 커버그라스의 전후와 좌우의 끝부위가 모따기기를 하지 않은 상태로 성형틀에서 한 공정으로 절곡되어 평판디스플레이기판과 몰딩접착됨을 특징으로 한다.The front, rear, left and right ends of the covergrass are bent in a molding process in a state without chamfering, and are characterized in that they are molded and bonded to the flat panel display substrate.

또한 상기 성형틀에서 한 공정으로 성형된 커버그라스의 모서리는 곡면으로 형성됨이 바람직하다.In addition, the edge of the cover glass molded in one process in the mold is preferably formed in a curved surface.

이하, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시 할 수 있을 정도로 본 발명에 의한 평판디스플레이의 커버그라스를 가장 바람직한 실시예를 첨부도면에 의거 상세하게 설명하면 다음과 같다.Hereinafter, the covergrass of the flat panel display according to the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. same.

본 발명에 의한 평판디스플레이의 커버그라스는 도 2 은 내지 도 4에서와 같이 커버그라스(10)는 전후와 좌우의 끝부위가 모따기기를 하지 않은 상태로 성형틀(12)에 올려 넣은 다음에 한 공정으로 절곡한 다음에 평판디스플레이기판(14)과 몰딩접착하여 구성된다.The cover glass of the flat panel display according to the present invention, as shown in Figures 2 to 4, the cover glass 10 is placed on the mold 12 without the chamfered front and rear and left and right sides After bending in the step, the flat panel substrate 14 is molded and bonded.

여기서 상기 성형틀(12)에서 한 공정으로 성형된 커버그라스(10)의 모서리(16)는 곡면으로 형성되고 전후와 좌우의 절곡된 부위는 소정높이로 밴딩되어 구성되어 평판디스플레이기판(14)위에 올려 놓고 몰딩하여 완성된다.Here, the edge 16 of the cover glass 10 formed in one step in the molding die 12 is formed into a curved surface, and the bent portions of the front, rear, left, and right sides are formed by bending at a predetermined height on the flat panel display substrate 14. It is finished by placing and molding.

이와 같은 본 발명의 커버그라스(10)는 비교적 얇고 넓으며 긴 판상의 유리를 소정크기로 재단하여 소정간격으로 절단하고, 단위 평판을 소정온도로 가열하여 열처리한 다음 단위 평판유리를 성형틀(12)에 올려 놓고 한번의 공정으로 전후 및 좌우를 절곡부위가 직각이 될 수 있도록 한다. 이어서 상기 커버그라스를 평판디스플레이 기판(14) 위에 올려놓고 기밀유지를 이루도록 몰딩제를 도포한다.The cover glass 10 of the present invention is cut to a predetermined interval by cutting a relatively thin, wide and elongated plate-shaped glass to a predetermined size, and heat the unit flat plate to a predetermined temperature and then heat the unit flat glass mold 12 ) So that the bending part can be right angle to front, rear, left and right in one process. Subsequently, the cover glass is placed on the flat panel display substrate 14 and a molding agent is applied to achieve airtightness.

상기와 같은 작업공정으로 커버그라스(10)의 전후와 좌우의 끝부위가 절곡되어 평판디스플레이기판(14)과 몰딩접착하여서 평판디스플레이장치를 얻을 수 있게 된다.By the above work process, the front, rear, left and right ends of the cover glass 10 are bent to be bonded to the flat panel display substrate 14 to obtain a flat panel display device.

따라서 평판디스플레이장치의 전면에 설치되는 커버그라스의 제조를 평판유리의 모서리에 모따기 작업을 하지 않고 성형틀에서 한 번의 공정으로 간단하게 제작을 이룰 수 있으면서 외관이 미려한 커버그라스를 제공한다.Therefore, the cover glass, which is installed on the front surface of the flat panel display apparatus, can be easily manufactured in a single process in a molding frame without chamfering the edge of the flat glass, and provides a beautiful cover glass.

이상의 설명에서와 같이 본 발명은, 평판디스플이 기판에 커버그라스를 보다 편리하고 양호하게 부착시킬 수 있도록 커버그라스의 가장자리를 모따기하지 않고 성형틀에서 한 번의 공정으로 커버그라스를 절곡하여 커버그라스를 평판디스플레이기판에 접착하므로 보다 편리하고 신속하며 외관히 미려한 평판디스플레이장치를 양산할 수 있는 것이다. 또한 이러한 커버그라스를 이용하면 다량생산을 신속하게 이룰 수 있으면서 작업공정도 간소화되면서 작업비용도 대폭적으로 절감할 수 있고, 아울러 커버그라스의 규격이 변화지 않게 양산하는 특성이 있다.As described in the above description, the present invention is to cover the cover glass by bending the cover glass in one step in the molding frame without chamfering the edge of the cover glass so that the flat panel display can attach the cover glass to the substrate more conveniently and satisfactorily. Since it adheres to a flat panel display substrate, it is possible to mass-produce a flat panel display device that is more convenient, faster and beautifully. In addition, the use of the cover glass can achieve a large amount of production quickly, while simplifying the work process and significantly reducing the work cost, and also has the characteristic of mass-production without changing the specifications of the cover glass.

따라서 본 발명은, 평판디스플레이기판에 부착하는 커버그라스가 신속하면서 간단한 작업공정으로 부착되어 작업의 편리성과 제품의 신뢰성 및 외관의 미려함을 이룰 수 있는 평판디스플레이의 커버그라스를 제공하는 효과가 있는 것이다.Therefore, the present invention has an effect of providing a cover glass of a flat panel display that can be attached to the flat panel display substrate in a quick and simple work process to achieve the convenience of work, the reliability of the product and the beauty of the appearance.
