Abstract: The present disclosure provides a drive circuit for a liquid crystal display device, including: a main reference table, having an entry for a drive voltage applied to a pixel at a border of a partitioned area; a sub reference table, having an entry for a drive voltage applied to a pixel in the partitioned area; and an area determining circuit element, for determining the partitioned area for a pixel according to a value of an input image signal for the pixel and determining whether the drive voltage is obtained by using the main reference table or by using the sub reference table, according to the partitioned area determined. Therefore, an appropriate over drive voltage may be obtained and the number of the entries may be lowed.
