Driving method for display panel

The present disclosure relates to a display technology field, and particular to a driving method for the display panel.

With development of display technology, because liquid crystal displays (LCDs) and such flat-panel display devices have advantages of high picture quality, power savings, thin bodies and wide application range, having gradually replaced cathode ray tube (CRT) display screen and being widely applied in mobile phones, televisions, personal digital assistants, laptops, desktop computers and such consumer electronics, having be the mainstream display devices.

Most LCDs in the current market are backlight LCDs, which include a liquid crystal display panel and a backlight module. The working principle of a liquid crystal display panel is to dispose liquid crystal molecules between a thin film transistor (TFT) array substrate and a color filter (CF) substrate, and applying a driving voltage between the two substrates to control a rotational direction of liquid crystal molecules to refract light out of the backlight module to generate images.

In a driving structure of a tradition liquid crystal display, there are data lines and gate lines on each pixel electrode respectively, this method can well control the opening of the gate electrode on each of the scan lines and the data input on each of the data lines. However, with improvement of resolution of a liquid crystal display panel, the number of data lines and gate lines also increases, as a result, the area occupied by the fan-out route of the data lines increases, which affects a penetration rate and display effect. To solve this problem, a multiplexing driving structure is applied widely, such as one-to-six demultiplexer (De-mux) driving structure, the so-called one-to-six De-mux driving structure refers to the technology of using a data signal to charge six columns of pixels using the principle of time-division multiplexing. Please refer to FIG. 1 , a display panel of a current one-to-six De-mux driving structure includes a plurality of driving units. Each of the driving units includes a plurality of pixels 100 which are arranged in a plurality of rows and four columns, twelve data lines 200 , a plurality of scan lines 300 and a demultiplexing module 400 . Each of the pixels 100 includes three subpixels 110 which are arranged in one of the rows, and the three subpixels 110 are a red subpixel r, a green subpixel g and a blue subpixel b sequentially. The colors of the subpixels 110 in a same column are same. One of the data lines 200 is correspondingly connected to a column of the subpixels 110 , and one of the scan lines 300 is correspondingly connected to one row of the subpixels 110 . The demultiplexing module 400 includes twelve thin film transistors T 10 which respectively correspond to the subpixels 110 , the drain electrodes of the thin film transistors T 10 are respectively connected to the data lines 200 which are connected to their corresponding columns of subpixels 110 . The source electrodes of the thin film transistors T 10 corresponding to the odd integer column subpixels 110 are accessed to a 2N+1th data signal D2N+1, where N is a natural number, and the source electrodes of the thin film transistors T 10 corresponding to the even integer column subpixels 110 are accessed to a 2Nth data signal D2N. A gate electrode of the thin film transistors T 10 which the red subpixels r of the first column pixels 100 and the second column pixels 100 correspond to is accessed a first demultiplexing signal DEMUX 10 ; a gate electrode of the thin film transistors T 10 which the green subpixels g of the first column pixels 100 and the second column pixels 100 correspond to is accessed a second demultiplexing signal DEMUX 20 ; a gate electrode of the thin film transistors T 10 which the blue subpixels b of the first column pixels 100 and the second column pixels 100 correspond to is accessed a third demultiplexing signal DEMUX 30 ; a gate electrode of the thin film transistors T 10 which the red subpixels r of the third column pixels 100 and the fourth column pixels 100 correspond to is accessed a fourth demultiplexing signal DEMUX 40 ; a gate electrode of the switch elements which the green subpixels g of the third column pixels 100 and the fourth column pixels 100 correspond to is accessed a fifth demultiplexing signal DEMUX 50 ; a gate electrode of the thin film transistors T 10 which the blue subpixels b of the third column pixels 100 and the fourth column pixels 100 correspond to is accessed a sixth demultiplexing signal DEMUX 60 .

During driving, the display panel includes a plurality of frame periods which are sequentially performed, each of the frame periods includes a plurality of row periods, the plurality of scan lines 300 are in a high electric level sequentially in the plurality of row periods. Please refer to FIG. 2 , in each of the row periods, the first demultiplexing signal DEMUX 10 , the second demultiplexing signal DEMUX 20 , the third demultiplexing signal DEMUX 30 , the fourth demultiplexing signal DEMUX 40 , the fifth demultiplexing signal DEMUX 50 and the sixth demultiplexing signal DEMUX 60 sequentially generate a high-level pulse to open the corresponding thin film transistors T 10 to transmit the data signal to the corresponding subpixels 110 . This driving method can reduce the area of the space occupied by fan-out route of the data lines to realize a narrow bezel. However, in the prior art, when scanning each of the row periods in each of the frame periods, a charging sequence of the plurality of the subpixels 110 is: first charging the pixels 100 of the first column and the second column, and then charging the pixels 100 of the third column and the fourth column. When the pixel is undercharged and the common voltage fluctuates, the display effect of the pixels 100 charged first is better than the display effect of the pixels 100 charged afterwards. Eventually, when the actual display is performed, a significant difference in brightness between the pixels 100 of the first column and the second column and pixels 100 of the third column and the fourth column as illustrated in FIG. 3 occurs, thereby stripes appearing on the images displayed by the display panel to affect the display effect.
