Patent number: 8764427Abstract: An apparatus for forming a pattern using a laser 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 light guide patterns of a discontinuous straight line shape. The controller transmits position signal of the light guide patterns 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 the header unit. The X-Y driver moves the header unit and the stage. The header unit moves along a first guide rail. The stage moves along a fixed second guide rail in the front and rear direction of the light guide panel.Type: GrantFiled: July 12, 2010Date of Patent: July 1, 2014Assignee: HB Technology Co., Ltd.Inventors: Deukil Park, Choongyop Rhew, Daisoung Park, Wonmyeong Kang
