Embodiment 1

[0042] figure 1 It is a schematic diagram of the existing pixel structure; figure 2 for figure 1 Waveform diagram of a sub-pixel monochrome display.

[0043] Such as Figure 1-Figure 2 As shown, the liquid crystal display panel includes m data lines D1'-Dm' (data line) and n scanning lines G1'-Gn' (Gate line). The data lines extend vertically, and the scan lines extend horizontally to intersect to form a plurality of sub-pixels. The sub-pixels of the same color can be set in the vertical direction, and the sub-pixels in the horizontal direction are arranged circularly in the order of red, green, and blue sub-pixels. One data line charges two adjacent columns of sub-pixels in a staggered manner to realize column flip and dot flip connections.

[0044]When the pixel structure performs monochrome display, a data line simultaneously charges the two adjacent pixels R1 and R2 in the same column, wherein the sub-pixel R1 is low voltage (dark state) due to the voltage of the pre...

Embodiment 2

[0090] This embodiment provides a liquid crystal display panel, a driving method thereof, and a terminal, which include most of the technical features of Embodiment 1, and the difference is that each pixel group includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. Sub-pixels, in each of the pixel groups, in each of the pixel groups, when the first sub-pixel is located in the x-th row and the y-th column of the pixel matrix, the second sub-pixel is located in the row (x+2) and column (y-1) of the pixel matrix, and the third sub-pixel is located at row (x+4) and column (y-2) of the pixel matrix.

[0091] Figure 10 A schematic structural diagram of the first pixel group provided in Embodiment 2 of the present application; Figure 11 A schematic structural diagram of the second pixel group provided in Embodiment 2 of the present application.

[0092] Specifically, such as Figure 10-Figure 11 As shown, when the first sub-pixel 101 of the first pixel group 110...

Abstract

The invention discloses a liquid crystal display panel and a driving method thereof, and a terminal. The display panel comprises a pixel structure, the pixel structure comprises more than two sub-pixels arranged in a pixel matrix, and data lines and scanning lines which are arranged vertically and crosswise, wherein the colors of three adjacent sub-pixels located in the same row are different, all the sub-pixels in the same column have the same color, each scanning line is located between two adjacent rows of the sub-pixels, each data line is located between two adjacent columns of the sub-pixels, each data line is connected to at least two pixel groups, and each pixel group comprises at least one scanning line and at least one data line; each pixel group comprises three sub-pixels with different colors, wherein the three sub-pixels are sequentially connected with a data line. The display panel also comprises a first driving unit which is electrically connected with the scanning lines, wherein the first driving unit inputs scanning signals to the scanning lines in a preset sequence. According to the invention, while secondary overturning is realized, the sub-pixels in the first row and the second row in one scanning period are subjected to heavy-load charging, so that the problem of horizontal bright and dark lines is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a liquid crystal display panel, a driving method thereof, and a terminal. Background technique [0002] In a liquid crystal display panel (Liquid Crystal Display, LCD), the double-flip pixel structure causes obvious horizontal bright and dark lines due to different pixel charging levels, which seriously affects the quality of the display screen. Contents of the invention [0003] The object of the present invention is to provide a liquid crystal display panel, its driving method, and a terminal, so as to solve the technical problem of the horizontal bright and dark lines of the double-inverted pixel structure. [0004] In order to achieve the above object, the present invention provides a liquid crystal display panel, which includes a pixel structure, including more than two sub-pixels arranged in a pixel matrix, and data lines and scanning lines arranged perpend...
