The invention discloses a light scanning type positioning apparatus based on LCD characteristics. The apparatus herein has the characteristics of high positioning precision, easy installation, low cost, easy operation and maintenance. The method herein involves: 1. the light scanning type positioning apparatus herein includes a signal source which provides a positioning light and a mobile device which requires positioning; 2. the signal source can scan the ground by transmitting light beams to entire columns in lateral direction and entire rows in longitudinal direction; 3. the mobile device can receive light beams which are transmitted by the signal source, and calculate the time length from the beginning of the scanning and the time when an optical receiving module receives the light beams, wherein t1 is obtained by scanning entire rows from top to bottom, and t2 is obtained by scanning entire columns from left to right, so that the position of the mobile device can be determined through t1 and t2. 本发明公开了种基
