Abstract:
1. A liquid crystal display device, comprising: a liquid crystal display panel having a plurality of gate lines and a plurality of data lines; a timing controller operable to control switching of a light transmission area and a light absorption area for a frame interval; a liquid crystal shutter operable to selectively absorb and transmit a light irradiated onto a pixel for the frame interval, wherein a plurality of electrode lines are provided in a horizontal direction and are symmetrically arranged at a front side of the liquid crystal display panel, and wherein the plurality of electrode lines include a pair of positioned at a front side of the pixel in the horizontal direction; and a shutter driver operable to alternately supply a current to the pair of electrode lines positioned at the front side of the pixel in response to a control of the timing controller, wherein the liquid crystal shutter includes an upper transparent substrate, a lower transparent substrate, absorbing polarizers attached onto the upper transparent substrate and the lower transparent substrate respectively and a liquid crystal for delaying a phase of the light in accordance with a voltage is injected between the upper transparent substrate and the lower transparent substrate, wherein the frame interval is 120 Hz ( 1/20 second), wherein the plurality of electrode lines is parallel to the plurality of gate lines, wherein the shutter driver is operable to shut off a current application into one electrode line to which a current is fed at the previous frame, for a pair of electrode lines positioned at the front side of each pixel and operable to apply a current to another electrode line in response to a control of the timing controller.
