Patent ID: 8592718

Claim:
An apparatus for forming a pattern using a laser, the apparatus comprising: a pattern storing unit for storing data on light guide patterns of a discontinuous straight line shape to be formed in a light guide panel; a controller for reading out position signals of the light guide patterns to be formed in the light guide panel, from the pattern storing unit, and transmitting the read-out position signals to an X-Y driver and simultaneously, transmitting a switching signal, which is generated on the basis of length information of the light guide patterns, to a laser oscillating unit; the laser oscillating unit for outputting a laser beam synchronized with a movement of a header unit, on the basis of the switching signal received from the controller; the X-Y driver for moving the header unit and a stage, on the basis of the position signals received from the controller; the header unit moving along a first guide rail in the left and right direction of the light guide panel by way of the X-Y driver, and forming the light guide patterns in the light guide panel by vertically downwardly reflecting and concentrating the laser beam output from the laser oscillating unit; and the stage moving along a fixed second guide rail in the front and rear direction of the light guide panel by way of the X-Y driver, and fixing the light guide panel, wherein the controller controls to provide a predetermined phase difference between an odd number line and even number line of the light guide patterns by adding a predetermined calibration value to X coordinates of position signals of the light guide patterns read out from the pattern storing unit, and the control is performed for at least one or more of the odd number line and the even number line.
