Problems solved by technology

[0004] 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

[0032] 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.

[0033] refer to Figure 1A with Figure 1B , Figure 1Ais 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.

[0034] 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 Transistor Array) 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...

Abstract

The invention discloses a display panel and a drive method thereof. The display panel comprises a color filter substrate, a liquid crystal layer, and a film transistor array substrate. The film transistor array substrate comprises a pixel unit array, a scanning line array, a data line array, and a drive circuit. The pixel unit array comprises at least two pixel rows and at least a pixel row combination. The pixel row combination comprises two pixel rows. The first scanning line and the second scanning line in the scanning line combination of the scanning line array are connected with the pixel units in the pixel rows. The data lines in the data line array are connected with each of the pixel unit in the two pixel rows in the pixel row combination. The drive circuit is used to generate a second drive signal according to a first drive signal. In the pixel row, the pixel units connected with the first scanning line and the pixel units connected with the second scanning line are arranged in a staggered manner. The display panel can make charging condition of the pixel units in different pixel rows balanced, preventing uniform charging.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel and a driving method thereof. 【Background technique】 [0002] 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. [0003] In practice, the inventors found that the prior art has at least the following problems: [0004] 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 brightness and da...
