Claim Text:
1. A liquid crystal display (LCD) for displaying three-dimensional stereo images, comprising: a backlight source; a first polarizer arranged on the backlight source; a first liquid crystal panel arranged on the first polarizer and comprising a first transparent electrode, a first indium tin oxide (ITO) film, a first orientation film, a liquid crystal layer, a second orientation film, a second ITO film, a second transparent electrode, and a color filter all sequentially arranged between two glass substrates, where the first liquid crystal layer is controlled by a first electrical field to produce a first polarization direction of light that passes through the first liquid crystal panel when a left-eye image is displayed and is controlled by a third electrical field to produce a third polarization direction of light that passes through the first liquid crystal panel when a right-eye image is displayed, wherein a first controller computes a first signal that applies the first electrical field to produce the first polarization direction and adjust a brightness of the left-eye image when the first signal takes a first value and applies the third electrical field to produce the third polarization direction and adjust a brightness of the right-eye image when the first signal takes a second value; a second polarizer arranged on the first liquid crystal panel, wherein a polarization direction of the second polarizer is perpendicular to a polarization direction of the first polarizer; and a second liquid crystal panel including a super twist nematic (STN) liquid crystal panel arranged on the second polarizer and comprising a second liquid crystal layer that is controlled by a second electrical field to produce a second polarization direction of light that passes through the second liquid crystal panel when a left-eye image is displayed and is controlled by a fourth electrical field to produce a fourth polarization direction of light that is deflected 270 degrees from the second polarization direction of light and that passes through the second liquid crystal panel when the right-eye image is displayed, wherein a second controller computes a second signal that applies the second electrical field to produce the second polarization direction and applies the fourth electrical field to produce the fourth polarization direction.
