Patent ID: 8292140

Claim:
A flat display panel cutting method, comprising: feeding a flat display panel loaded on a conveyor to a cutting area and a spraying area; forming primary cracks on the cutting area by use of cutting means, the primary cracks including two or more first cracks spaced apart from each other in the X-axis direction and two or more second cracks spaced apart from each other in the Y-axis direction; and growing secondary cracks on the spraying area by use of spraying means by spraying a high temperature steam onto the first cracks or second cracks of the primary cracks formed on the flat display panel, further comprising adsorbing one portion of the flat display panel and separating the same from the flat display panel by use of a clamp area positioned after the cutting, wherein, in the growing, the cracks are grown while moving the spraying means in the Y-axis direction, wherein, in the growing, the cracks are grown by fixing the spraying means, wherein the spraying means comprises at least one steam bar disposed in one direction, wherein the steam bar is disposed at the same interval as the interval of the first cracks or second cracks, wherein, in the feeding, the conveyor is disposed such that the flat display panel can pass through the cutting area in the X-axis direction and pass through the spraying area in the Y-axis direction, wherein, in the formation of cracks, scribing wheel which rotates in tight contact with the flat display panel or a laser irradiation unit for irradiating a laser to the flat display panel is used as the cutting means, wherein, in the formation of cracks, the cutting means is positioned at least one of the upper and lower ends of the conveyor.
