Liquid crystal display panel and liquid crystal display device

The present invention relates to a liquid crystal display panel and a liquid crystal display device.

With the advancement of technology, display devices have been widely used in various fields, especially liquid crystal display devices, which have gradually replaced traditional cathode ray tube display devices due to their superior characteristics such as slimness, low power consumption and no radiation. It is used in many types of electronic products, such as mobile phones, portable multimedia devices, notebook computers, LCD TVs and LCD screens.

In the case of a liquid crystal display device, since the characteristics of the liquid crystal molecules cannot be fixed at a certain voltage all the time, otherwise the time is long, even if the voltage is canceled, the liquid crystal molecules cannot be rotated according to the change of the electric field due to the destruction of the characteristics. To form different gray levels. Therefore, at intervals, the voltage must be restored to the original state to avoid damage to the characteristics of the liquid crystal molecules. To solve this problem, there are currently three common types of voltage transition modes: column inversion, row inversion, and dot inversion.

Referring to FIG. 1 , FIG. 1 is a schematic diagram of a conventional liquid crystal display panel 10 including a plurality of scan lines 11 ₁ - 11 _n , a plurality of data lines 12 ₁ - 12 _{n ,} and a plurality of pixels 13 . Each of the pixels 13 includes a thin film transistor Q01 and a pixel capacitor C01, wherein the two ends of the pixel capacitor C01 are respectively coupled to the thin film transistor Q01 and a common electrode E01, and the thin film transistor Q01 is respectively connected to the pixel. The capacitor C01 and the corresponding scan line are coupled to the data line.

In the liquid crystal display panel 10, the pixels are arranged in an array, and the following is described by a row of pixels 14 and a column of pixels 15. Each of the pixels 13 in the line of pixels 14 is coupled to the same data line (here, the data line 12 _{1 is taken} as an example), and each of the pixels 13 in the column of pixels 15 is connected to the same scanning line (here The scan line 11 _{1 is} coupled as an example. In other words, in the conventional liquid crystal display panel 10, each pixel in each row of pixels 14 is coupled to the same data line, and each pixel in each column of pixels 15 is coupled to the same scan line.

2A to 2C, when the output signals of the voltage transition mode of the conventional liquid crystal display panel 10 are respectively line inversion (FIG. 2A), column inversion (FIG. 2B), and dot inversion (FIG. 2C). When driving, the voltage polarity inversion mode output from the data line driving circuit is the same as the voltage polarity inversion mode in which the pixel is driven.

The dot inversion driving mode can significantly reduce the phenomenon of crosstalk and flicker by the characteristics of different polarities of adjacent pixel units, thereby having better display quality. However, since the dot inversion driving mode requires a higher voltage and the voltage needs to be constantly reversed, there is a problem that power consumption is large. In addition, although the row inversion driving mode and the column inversion driving mode require only a relatively low voltage and are relatively power-saving, the phenomenon of picture crosstalk and flicker is conspicuous, and thus the display quality is inferior to the dot inversion driving mode.

In summary, a liquid crystal display panel and a liquid crystal display device according to the present invention change the voltage polarity inversion mode of the output signal of the data line driving circuit by changing the connection mode of each pixel and each scanning line. The voltage polarity inversion mode that the element is driven to display is different. Thereby, it is possible to reduce power loss while maintaining good display quality.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
