Abstract: A wireless positioning server using clock offset compensation and a wireless positioning method using the same. The wireless positioning server using clock offset compensation estimates a precise position of a tag requiring position information by effectively predicting information regarding a distance between a beacon for performing positioning and the tag requiring position information. An error in the positioning estimation result due to a clock offset is minimized by measuring a relative clock frequency ratio between beacons and by compensating for clock frequencies of the beacons when a distance between a beacon and a tag is estimated.

The mask includes a group of slits that are inclined at a predetermined angle with respect to a scan direction and a group of slits including slits inclined at a predetermined angle with respect to the former group of slits. The groups of slits are separated by an interval along the scan direction, and the substrate and/or mask is moved by the interval between irradiation by laser through the slits. Further, there are provided a method for crystallizing silicon using the mask and a display device. By reducing the number of grain boundaries that extend horizontally or vertically on the substrate, the invention obviates a design limitation associated with the directional anisotropy in sequential lateral solidification (SLS) technique.
