Abstract
An apparatus for forming a pattern is provided. The apparatus includes a pattern storing unit, a controller, a laser oscillating unit, an X-Y driver, a header unit, and a stage. The pattern storing unit stores data on a light guide pattern. The controller reads out the data on the light guide pattern, and transmits a position signal of each light guide pattern to the X-Y driver and simultaneously, transmits a switching signal to the laser oscillating unit. The laser oscillating unit outputs a laser beam synchronized with a movement of a header unit. The X-Y driver moves the header unit and the stage. The header unit moves along a fixed first guide rail in the left and right direction of the light guide panel. The stage moves along a fixed second guide rail in the front and rear direction of the light guide panel.
