Document Type and Number:
Japanese Patent JP5235896
Kind Code:
B2
Abstract:
The present invention relates to a blacking apparatus and method, which eliminate light leakage caused by impurities present in liquid crystal cells. The apparatus for blacking a liquid crystal panel according to the present invention includes a laser oscillation unit (100), a beam delivery unit (120), and a scan unit (130). The laser oscillation unit includes a plurality of laser oscillators, beam adjustment means for adjusting intensity of a laser beam emitted from each laser oscillator, beam formation means for converting a profile of the laser beam, and a half mirror having characteristics for selectively transmitting or reflecting the laser beam. The beam delivery unit switches a direction of the laser beam. The scan unit adjusts a direction of the laser beam so that the laser beam is radiated onto a region of the liquid crystal panel desired to be blacked.
