Problems solved by technology

[0006] In the process of using the scanning drive circuit to control the opening of the TFT (Thin Film Transistor, thin film transistor) switch to control the charging of the pixel unit, for different pixel units, there will often be uneven charging due to the difference in the pre-charged potential. In this case, this will lead to a more obvious difference between the brightness and darkness of the overall picture, which will reduce the display quality of the display panel

Embodiment Construction

[0036] The word "embodiment" as used in this specification means serving as an example, instance or illustration. Furthermore, the article "a" as used in this specification and the appended claims may generally be construed to mean "one or more" unless specified otherwise or clear from context to refer to a singular form.

[0037] refer to Figure 1A and Figure 1B , Figure 1A is a schematic diagram of the first embodiment of the display panel of the present invention, Figure 1B for Figure 1A A schematic diagram of the signal.

[0038] The first embodiment of the display panel of this embodiment includes a color filter (CF, Color Filter) substrate, a liquid crystal (LC, Liquid Crystal) layer, and a thin film transistor array (TFT Array, Thin Film TransistorArray) substrate. The color filter substrate and the thin film transistor array substrate are superimposed and combined into one, and the liquid crystal layer is arranged between the color filter substrate and the thin fi...

Abstract

The invention discloses a display panel and a driving method thereof. The display panel includes: a color filter substrate; a liquid crystal layer; a thin film transistor array substrate, and the thin film transistor array substrate includes: a pixel unit array, a scanning line array, a data line array and a driving circuit; the pixel unit array includes at least two pixel rows and at least one pixel column combination, and the pixel column combination includes two pixel columns; the first scan line and the second scan line in the scan line combination of the scan line array are all connected to the pixels in the pixel row Unit connection; the data line in the data line array is connected to each pixel unit of the two pixel columns in the pixel column combination; the driving circuit is used to generate the second driving signal according to the first driving signal; in the pixel row, it is connected with the first scanning The pixel units connected with the line and the pixel units connected with the second scanning line are alternately arranged. The invention can balance the charging conditions of the pixel units in different pixel rows, and avoid uneven charging.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to a display panel and a driving method thereof. [0003] 【Background technique】 [0004] The traditional GOA (Gate driver On Array) technical solution is generally to form the scanning drive circuit on the thin film transistor array substrate in the existing manufacturing process of the thin film transistor array substrate, so as to realize the pixel array on the thin film transistor array substrate. line-by-line scan. [0005] In practice, the inventors found that the prior art has at least the following problems: [0006] In the process of using the scanning drive circuit to control the opening of the TFT (Thin Film Transistor, thin film transistor) switch to control the charging of the pixel unit, for different pixel units, there will often be uneven charging due to the difference in the pre-charged potential. In some cases, this will lead to obvious differences in br...
