Embodiment Construction

[0037] First, the concept of the present invention will be described.

[0038] In the scribing system and method according to the present invention, a technique is provided in which the scribing process can be performed in the opposite direction without raising the wheel.

[0039] That is, in the scribe line forming method shown in FIG. The direction is preset for the Y scribe on the substrate. Next, for a second scribing operation along dotted line 202 , the wheel is raised and the head is moved from position b to position c in the direction indicated by dotted line 221 . The wheel then performs a second scribing operation from position c to position d in the Y direction shown by solid line 212 .

[0040]When the wheel reaches position h after repeating this operation, the head on which the wheel is mounted is raised and then moved to position i in the direction shown by dot-dash line 222 for marking in the X direction.

[0041] Next, the wheel mounted on the head performs...

Abstract

Provided is a scribing system and method for forming a scribe line on a substrate using a wheel mounted on a head, the scribing method including: a first process of forming a scribe line in a first direction of the substrate; a second process of switching the direction of the wheel into a second direction different from the first direction in a dummy region of the substrate, and then moving the wheel a predetermined distance; a third process of switching the direction of the wheel into a third direction reverse to the first direction in the dummy region of the substrate, and then forming a scribe line; and a fourth process of switching the direction of the wheel into the second direction in the dummy region of the substrate, and then moving the wheel a predetermined distance, wherein the first to fourth processes are continuously performed. Using the scribing method described above, it is possible to reduce operation time required for scribe lines.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of Korean Patent Application No. 2007-0079943 filed on Aug. 9, 2007, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a scribing system and method, and more particularly to a scribing system using wheels mounted on It also relates to a scribing method using the scribing system to continuously form scribing lines. Background technique [0004] In a display device using a flat display panel such as a liquid crystal display panel, a plasma display panel, an organic electroluminescent (EL) display panel, etc., two sheets of brittle glass are bonded together to constitute the panel. When manufacturing such a panel, a mother glass substrate (hereinafter, referred to as "substrate") is cut into a predetermined shape. In this cutting process, scribe lines are formed along the lines to be scribed on the substra...
