Abstract
A pattern forming apparatus for a light guide panel is provided. The apparatus may include a pattern design system, a control system, a header moving unit including an XY moving unit and a header unit, a laser system, beam splitters, and an optical unit. The pattern design system may have an input of data on a pattern. The control system may connect with the pattern design system and transmits a position signal. The XY moving unit may mechanically move up/down and left/right in response to the position signal. The header unit may be coupled with the XY moving unit and reflects a scanned laser beam. The laser system may output a laser beam by a pulse signal. The beam splitters may split a laser beam into two or more laser beams. The optical unit may reflect and collect the two or more laser beams.
