| 摘要 |
The present invention relates to a device for processing a light guide plate and comprises a laser generation unit generating a laser beam; a diffraction grid holder unit comprising a diffractive optical element (DOE) lens which passes and splits the laser beam; and a focus lens holder unit comprising a focus lens positioned in the lower part of the diffraction grid holder unit. The diffraction grid holder unit comprises a plurality of diffraction grids that the number of splitting beam is different. The diffraction grids are moved to a transparent position that the laser beam selectively passes. |
