Method of manufacturing cover glass for flat panel display and articles thereof
The present invention relates to a method for manufacturing a cover glass of a flat panel display device and an article thereof, and more particularly, to manufacture a cover glass for forming an external appearance of a flat panel display in a short time, automatically and simply, easily and easily molded into a flat panel display. The present invention relates to a method for manufacturing a cover glass of a flat panel display and an article thereof, which can reduce production processes and reduce production costs.
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.
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 short time automatically and simply and easily molded to easily adhere to the flat panel display to reduce the work process At the same time to provide a cover glass manufacturing method of the flat panel display and the article that can reduce the production cost.

A method for producing a cover glass of a flat panel display according to the present invention by achieving the above object comprises: a cutting step of dividing the plate glass into equal parts at predetermined intervals; A cutting step of bending a guide groove at front, rear, left and right ends of the unit flat glass obtained after the cutting step; Heat-treating the unit plate after the cutting process; A bending step of pressing the V groove of the unit plate obtained by the step with a predetermined force; A cooling step of cooling the covergrass having the bending step; The cooled cover glass is placed on a flat panel display substrate, characterized in that the molding process of forming a gas tight.
In addition, in order to achieve the above object, the cover glass of the flat panel display is characterized in that the front and rear and left and right ends of the cover glass are molded and bonded to the flat panel display substrate.
Hereinafter, a method for manufacturing a cover glass of a flat panel display according to the present invention, and the most preferred embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention. If you explain it as follows.
Cover glass manufacturing method and structure of the flat panel display according to the present invention is completed after the process as shown in Figures 2 to 4 will be described as follows.
1st process (cutting process); It is cut to a predetermined interval by cutting to a predetermined size on a relatively thin, wide and long plate-like glass.
2nd process (edge chamfering process); Chamfer the angled parts of the cut unit flat glass so that the edges meet at right angles.
3rd process (cutting process); It is a cutting process for processing the bending guide groove in the front, rear, left and right ends of the unit plate glass obtained after the cutting process. The bending guide groove may be any one of the V-shaped, semi-circle, square, semi-ellipse to achieve a perpendicular maintenance of the bending point portion while making the bending of the edge of the unit plate glass in the bending process to be described later.
4th process (heat processing process); After the cutting process, the unit plate is heated to a predetermined temperature and heat treated.
5th process (banding process); The edges of the unit flat glass obtained by the heat treatment process step are bent at right angles.
6th process (cooling process); Cooling is carried out within a predetermined temperature so as to maintain a rectangular shape of the bent portion of the cover glass formed by the bending process.
7th process (molding process); The cooled covergrass is placed on a flat panel display substrate and a molding agent is applied to achieve airtightness.
By the above work process, the front, rear, left and right ends of the cover glass 10 are bent and bonded to the flat panel display substrate 12 to obtain the flat panel display device 14.
Therefore, the manufacturing of the cover glass installed on the front surface of the flat panel display device can be easily achieved, while achieving a mass production of cost reduction while reducing labor and labor by rapid and accurate molding.
Although the present invention has been described only in the above embodiments, it is not limited thereto and various modifications and changes may be made without departing from the scope and spirit of the present invention.
As described above, the present invention can be obtained by performing the chamfering, heat treatment, bending and cooling process of the cover glass so that the flat display can attach the cover glass to the substrate more conveniently and favorably. By adhering to a flat panel display substrate, a flat panel display device can be mass produced more conveniently and quickly. 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.
Therefore, the present invention has an effect of providing a cover glass manufacturing method of the flat display that can be attached to the flat panel display substrate in a quick and simple work process to achieve the convenience of operation and the reliability of the product and the article. .
