Problems solved by technology

[0003] In the prior art, a louver shielding film is usually added on the liquid crystal display panel or a liquid crystal display device with a double backlight system is used to switch between a wide viewing angle and a narrow viewing angle, but this will increase the thickness of the liquid crystal display panel and increase the control circuit. , and it is inconvenient to use

Abstract

The invention discloses a liquid crystal display device and a drive method thereof. A view angle controlling electrode is arranged on a second substrate (a color filter substrate) of the liquid crystal display device, and voltage is applied to the view angle controlling electrode when a narrow view angle is required, so that an electric filed perpendicular to the direction of a panel is generated among the view angle controlling electrode, and a pixel electrode and a public electrode which are arranged on a first substrate (an array substrate), liquid crystal molecules are subjected to an angle inclination change in the vertical direction, the objectives of inclined-view dark-state light leakage, reduction of the contrast, narrowing of the view angle, and narrow-view-angle display are realized. Accordingly, by adjusting the voltage applied to the view angle controlling electrode, switching between the mode of the wide view angle and the mode of the narrow view angle can be achieved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display technology continues to develop toward increasing the display viewing angle. The existing in-plane switching (IPS) and fringe field switching (FFS) can both realize a wider display viewing angle. The electrodes of the traditional TN-type liquid crystal display technology are on two opposite substrates, the direction of the applied electric field is perpendicular to the substrates, and the liquid crystal molecules move in parallel and vertical directions relative to the substrates; while the electrodes of the IPS-type liquid crystal display technology are set on On the same substrate, the electric field generated between the electrodes is horizontal, and positive liquid crystals are used at the same time (that is, the axial direction of the liquid crystal molecu...
