Abstract:
A liquid crystal display (LCD), comprising:an LCD panel including a plurality of gate lines, a plurality of data lines insulated from and intersecting the gate lines, and a plurality of TFTs each having a gate electrode connected to one of the gate lines and a source electrode connected to one of the data lines; a gate driver for sequentially supplying gate drive signals to the gate lines to turn the TFTs ON; and a data driver that groups the data lines into an X-number of blocks, each block having a predetermined number of data lines, and applies image signals to the data lines in an (n)th block, and precharging voltages to the data lines in the (n+j)th block, wherein the data driver comprises: a block select signal generator for generating block select signals to select one of the blocks; an image signal processor that generates the image signals for the data lines in a selected block; a precharging signal generator that generates the precharging voltages for the data lines in the selected block; the X-number of image signal select switch blocks for switching each of the image signals for application to one of the blocks; and the X-number of precharging select switch blocks for switching each of the precharging voltages for application to one of the blocks, wherein an (n)th block select signal generated from the block select signal generator simultaneously activates the (n)th image signal select switch block from an OFF state to an ON state and the (n+j)th precharging signal select switch block from an OFF state to an ON state.
