Abstract
The present invention relates to a liquid crystal display panel having an adjusting device and an adjusting method thereof. The adjusting device is configured to transmit a recovery voltage signal having a recovery voltage to a common electrode line corresponding to a scan line when a low-voltage scan signal is transmitted to the scan line, and form an adjusted voltage lower than the recovery voltage on the common electrode line when a high-voltage scan signal is transmitted to the scan line. The invention can reduce effectively flicker of a liquid crystal display panel and improve comfortableness of a user when viewing.
Claims24
A liquid crystal display panel, comprising:
- a plurality of scan lines;
- a plurality of data lines;
- a plurality of common electrode lines;
- and
- an adjusting device, wherein the adjusting device is configured to transmit a recovery voltage signal having a recovery voltage to a common electrode line corresponding to a scan line when a low-voltage scan signal is transmitted to the scan line, and form an adjusted voltage lower than the recovery voltage on the common electrode line when a high-voltage scan signal is transmitted to the scan line.
An adjusting method of a liquid crystal display panel, comprising:
- transmitting a scan signal in sequence to each scan line;
- forming an adjusted voltage on a corresponding common electrode line when a high-voltage scan signal is transmitted to a scan line;
- transmitting to the common electrode line, a recovery voltage signal having a recovery voltage higher than the adjusted voltage when a low-voltage scan signal is transmitted to the scan line;
- and
- compensating positively for a feedthrough voltage by a coupled voltage resulting from a voltage of the common electrode line and a pixel electrode on the scan line.
A liquid crystal display comprising:
- scan lines and data lines arranged in a matrix,
- a plurality of common electrode lines,
- a data driver coupled with the data lines,
- a scan driver coupled with the scan lines, and
- an adjusting device, wherein the adjusting device is configured to transmit a recovery voltage signal having a recovery voltage to a corresponding common electrode line when a low-voltage scan signal is transmitted to a scan line, and form an adjusted voltage lower than the recovery voltage on the common electrode line when a high-voltage scan signal is transmitted to the scan line.
