Embodiment Construction

[0024] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve corresponding technical effects in the present invention. The embodiments of the present application and the various features in the embodiments can be combined with each other under the premise of no conflict, and the formed technical solutions are all within the protection scope of the present invention.

[0025] by right figure 1 The structure of the pixel unit shown is analyzed, and it can be found that the cause of the flickering and image retention of the LCD screen is mainly due to the influence of the parasitic capacitance of the switching element TFT3, combined below figure 1 Describe in detail.

[0026] figure 1 The pixel unit in is divided into two sub-pixel units, as shown in the area...

Abstract

The invention discloses a liquid crystal display panel. The liquid crystal display panel comprises an array substrate. A plurality of scanning lines, a plurality of data lines and a plurality of pixel units are distributed on the array substrate. Each pixel unit is composed of a first subpixel unit and a second subpixel unit which share the same data line and use different scanning lines respectively, wherein the first subpixel unit is started through the scanning voltage of the first scanning line, data signals of the data line are received, and the first pixel voltage is achieved; the second subpixel unit is started through the scanning voltage of the second scanning line in the driving period of the first subpixel unit, data signals of the data line are received, and the second pixel voltage is achieved. The drive of the second subpixel units is finished in the driving period of the first subpixel units. By means of the liquid crystal display panel, the effect of secondary coupling voltage to a liquid crystal display in the alternating current drive can be eliminated, the aperture ratio of the pixel unit is increased, and the display effect of the liquid crystal display can be improved.

Description

technical field [0001] The invention relates to the display field of liquid crystal displays, in particular to a liquid crystal display panel and a driving method thereof. Background technique [0002] In recent years, vertical alignment (Vertical Alignment, VA) liquid crystal displays have been more and more widely used due to their advantages of wide viewing angle, high contrast, and no need for rubbing alignment. The VA liquid crystal display performs domain division processing on the liquid crystal layer, so that the negative liquid crystal molecules in the vertical state are tilted under the action of the voltage applied by the two substrates, thereby achieving the purpose of improving the viewing angle and color shift of the liquid crystal display. [0003] Since only four-domain display can be formed at most physically, the liquid crystal display with eight-domain display is generally realized by controlling the rotation angle Φ of liquid crystal molecules. figure 1 ...
