Array substrate and liquid crystal display

Abstract

The invention provides an array substrate and a liquid crystal display. The array substrate comprises a plurality of pixel units arranged in an array manner, a data driver and a plurality of data cables, wherein each pixel unit comprises a plurality of sub-pixels arranged along the row direction and having different colors, and the data driver provides drive voltage for the plurality of sub-pixels through the plurality of data cables. In the same frame of picture, the polarities of driving voltages of the adjacent sub-pixels of the same pixel unit are opposite, and the polarities of driving voltages of the sub-pixels having the same color of each two adjacent pixel units in the same row are opposite. Through the above method, the darkness and brightness change of the array substrate is homogenized, so that the problem that when pure color or special points are displayed, the display is poor, or the quality of the product is reduced, is solved, and the display effect is optimized.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate and a liquid crystal display. Background technique [0002] The LCD panel industry has experienced decades of development. The VA (vertical alignment) display mode has become a common display mode for large-size TV TFT-LCDs due to its advantages such as wide viewing angle, high contrast, and no need for frictional alignment. Large size, high ppi (pixels per inch) products are the consistent pursuit of the display industry, and high ppi will lead to extremely low penetration rate, such as the current 60-inch 8kTV on the market, the penetration rate is only about 2%, it needs to be matched with The extremely high brightness backlight greatly increases the product cost. For this reason, WRGB technology came into being, changing the traditional RGB color resistance combination into WRGB, which can effectively increase the penetration rate of the pro...

AI Technical Summary

Problems solved by technology

[0003] The current WRGB panel often appears when displaying a solid color or a special point, and the driving voltage of the entire row or column of pixels is often the same polarity, which will have a coupling effect with the voltage of the common electrode and is very obvious, and the potential of the common electrode will change with time. Coupled with the transition of the driving data signal, it will cause problems such as misalignment or flickering on the panel, and reduce product quality.
