Problems solved by technology

However, the above two methods currently have certain limitations
[0004] Among them, the first method is limited by its scanning method, which requires the BLU to be designed only for single short or double short, and the effect of improving Cross talk is not good.
The second method requires a higher refresh rate, usually 240Hz, because it needs to insert a black frame when the left and right eye signals are switched, which will reduce the charging time to half of 120Hz, causing the panel to be insufficiently charged risk, which in turn leads to the appearance of spots (Mura), which greatly affects the quality of liquid crystal display devices

Abstract

The invention discloses a liquid crystal display device as well as a pixel structure and a driving method thereof. According to the pixel structure, a first scanning line of the pixel structure transmits a first scanning signal for starting a first switching unit to charge a pixel electrode; when the charging is finished and the pixel electrode is at an electric quantity keeping state, a second scanning line transmits a second scanning signal for starting a second switching unit; and a public electrode wire is used for providing public voltage to the pixel electrode to tension the voltage of the pixel electrode to public voltage. With the adoption of the manner, on one hand, the charging time of the pixel electrode and the resolution of the liquid crystal display device are guaranteed; and on the other hand, a black insertion technology is realized and the effect of reducing 3D (Three Dimensional) cross talk is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device, a pixel structure and a driving method thereof. Background technique [0002] The 3D shutter (Shutter Glass) technology generally has the problem of large crosstalk. To solve this problem, there are currently two commonly used solutions in the existing technology: [0003] The first is the backlight scanning mode (BLU Scanning Mode), and its basic frequency is 120Hz; the second is the black insertion technology (Black Insertion), that is, the backlight blinking mode (BLU Blinking Mode), which is passed when the left and right eye signals are switched. It can be realized by inserting a black frame, for example, inserting a frame of black frame after the end of the right-eye frame, and then scanning the left-eye frame. However, the above two methods currently have certain limitations. [0004] Among them, the first method is limited by its scanni...
