Example Embodiment

[0015] The display area of ​​the display device is defined by a plurality of intersecting data lines and gate lines. Since the gate lines are scanned row by row, each row of the gate lines can also be called a scan line. During the scanning process, the scan always starts from the upper left corner of the image and moves forward horizontally, while the scanning point also moves down at a slower rate. When the scanning point reaches the right edge of the image, the scanning point quickly returns to the left, and then starts scanning the second line below the starting point of the first line. The return process between lines is called horizontal blanking. A complete image scanning signal consists of all the line signal sequences separated by the horizontal blanking interval, which is called a frame. After scanning a frame, the scanning point returns from the lower right corner of the image to the upper left corner of the image to start scanning a new frame. This time interval is ...

Abstract

The invention discloses a display device driving method and a display device. The display device comprises a grid driver and a source electrode driver. Scanning lines are sequentially unpacked one by one from scanning signals output by the grid driver, and the scanning lines in set number correspond to a frame picture. When the scanning lines are unpacked, data signals output from the source electrode driver are input into pixel units of the scanning lines through a data line, and a coupling capacitor is arranged between the data line and a public electrode. The display device driving method includes inputting set data signals into the data line for offsetting coupling action of the data line to the public electrode during unpacking the scanning line corresponding to the frame picture at the field blanking time before unpacking the first scanning line corresponding to one frame picture. Accordingly, the public electrode can be driven in a manner of fluctuation complementing with the data signals of the frame picture during unfolding the frame picture, and voltage of the public electrode is stabilized and stability of the picture is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving method of a display device and a display device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. With the rapid development of TFT-LCD, large-sized and low-cost high-load products, such as large-sized televisions (television, TV), appear. The emergence of this type of product puts forward higher requirements for picture quality. [0003] In the prior art, when a thin film transistor (Thin Film Transistor, TFT) pixel is working normally, the scanning lines corresponding to a frame of picture are sequentially turned on line by line, and when a scanning line is turned on, the data signal is input into the scanning line through the data line. pixel unit. However, there is usually a ...
