Sealing apparatus and method of manufacturing flat display device using the same
View Patent ↗A sealing apparatus and a method of manufacturing a flat display device using the sealing apparatus. The sealing apparatus to attach a first substrate and a second substrate to each other using an attachment member disposed between the first and second substrates, the sealing apparatus comprises a stage on which the first substrate is seated, a halogen lamp irradiating light, and a reflector reflecting light irradiated from the halogen lamp to the attachment member.
1. A method of manufacturing a flat display device using a sealing apparatus that attaches a first substrate and a second substrate with an attachment member and has a halogen lamp, the method comprising:
disposing the attachment member between the first substrate and the second substrate;
attaching the first substrate and the second substrate to each other;
seating the attached first substrate and second substrate on a stage of the sealing apparatus;
converging the light irradiated from the halogen lamp onto the attachment member in a manner that the light is irradiated to the attachment member in a whole section area of the first substrate and the second substrate in one direction along a surface of the second substrate at the same time;
irradiating light to the attachment member while moving the halogen lamp in a direction crossing the one direction; and
hardening the attachment member melted by the irradiated light to attach the first substrate and the second substrate to each other,
wherein the light is irradiated to the attachment member while the light passing through the first substrate and the second substrate is reflected by a reflecting plate disposed between the first substrate and the stage.
2. The method of manufacturing the flat display device of claim 1 , wherein in the converging the light irradiated from the halogen lamp and the irradiating the light onto the attachment member, the light is reflected and converged by a reflector, and is irradiated onto the attachment member.
3. The method of manufacturing the flat display device of claim 1 , wherein in the converging the light irradiated from the halogen lamp and irradiating the light to the attachment member, the one direction along a surface of the second substrate is a lengthwise direction of a side of the second substrate.
4. The method of manufacturing the flat display device of claim 1 , wherein the irradiating light to the attachment member while moving the halogen lamp in a direction crossing the one direction is irradiating light to the attachment member while moving the halogen lamp in a direction perpendicular to the one direction.
5. The method of manufacturing the flat display device of claim 1 , wherein the attachment member is composed of a frit material.
6. The method of manufacturing the flat display device of claim 1 , further comprising disposing a light-blocking member on the second substrate, the light-blocking member allowing light irradiated from the halogen lamp to pass therethrough to the attachment member, and not allowing light to pass therethrough to areas not coated with the attachment member, between the seating the first substrate and the second substrate that are attached to each other on a stage of the sealing apparatus and the converging the light irradiated from the halogen lamp and irradiating the light to the attachment member.
7. The method of manufacturing the flat display device of claim 6 , wherein the light-blocking member is disposed apart from the second substrate by a predetermined gap.
8. The method of manufacturing the flat display device of claim 1 , wherein an output power of the halogen lamp is about 2 to 10 KW.
