Driving method for display panels

Abstract

The invention provides a driving method for display panels. According to the driving method for display panels of the invention, by making a first multiplexing signal, a second multiplexing signal, athird multiplexing signal, a fourth multiplexing signal, a fifth multiplexing signal and a sixth multiplexing signal generate a high-level pulse in a preset order in each first line period of a (2*i-1)th multiplexing period and making the first multiplexing signal, the second multiplexing signal, the third multiplexing signal, the fourth multiplexing signal, the fifth multiplexing signal and the sixth multiplexing signal generate a high-level pulse in order contrary to the preset order in each second line period of a (2*i)th multiplexing period, the fringe sense of the screen displayed on a display panel can be eliminated, and the display quality can be enhanced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of a display panel. Background technique [0002] With the development of display technology, liquid crystal display (Liquid Crystal Display, LCD) and other flat display devices have gradually replaced cathode ray tubes (CathodeRay Tube, CRT) display screens are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to inject liquid crystal molecules between the thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT...

Problems solved by technology

This driving method can reduce the area occupied by the fan-out routing of the data lines to achieve a narrow border. However, in each row period, the charging sequence of the multiple sub-pixels 110 is: the first and second columns of pixels 100 Red sub-pixel r, green sub-pixel g in the first and second columns of pixels 100, blue sub-pixel b in the first and second columns of pixels 100, red in the third and fourth columns of pixels 100 The sub-pixel r, the green sub-pixel g in the third column and the fourth column pixel 100, and the blue sub-pixel b in the third column and the fourth column pixel 100 are first charged when the pixel charge is insufficient and the common voltage fluctuates. The display effect of the charged sub-pixel 110 is better than that of the sub-pixel 110 charged later, so that the display effect of the red sub-pixel r in the first and second column pixels 100 is better than that of the third and fourth column pixels The display effect of the red sub-pixel r in 100, the display effect of the green sub-pixel g in the first column and the second column of pixels 100 is better than the display effect of the green sub-pixel r in the third and fourth column of pixels 100, The display effect of the blue sub-pixel b in the first column and the second column of pixels 100 is better than the display effect of the blue sub-pixel b in the third column and the fourth column of pixels 100, so that as image 3 As shown, there is a difference in luminance between the pixels 100 in the first and second columns and the pixels 100 in the third and fourth columns, which will eventually lead to stripes in the picture displayed on the display panel and affect the display effect.
