Embodiment Construction

[0027] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a display device including a display panel, a scan signal driving module, and a data signal driving module. The display panel includes a scan line, a plurality of data lines,and a plurality of pixel units. The scan line includes 2n pairs of first scan lines and a plurality of pairs of second scan lines; a plurality of data lines are arranged in a column direction; a plurality of pixel units are disposed between each pair of second scan lines and arranged in a matrix mode; each adjacent two columns of pixel units share one data line, adjacent pixel units of the same row are connected to different scan lines, the pixel units with one pixel unit interval for each other in the same row are connected to the same scan line, the scan signal driving module is configured to simultaneously input a scan pulse signal to the Nth scan line and the N+4nth scan line; the data signal driving module is configured to input a square wave data signal to the data line, the pixel unit connected to the Nth+4n scan line is pre-charged, and the vertical bright line on the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for driving a display panel and a display device. Background technique [0002] Existing liquid crystal display devices usually have three driving structures: standard speed driving type, double speed driving type and triple speed driving type. When the resolution of the display device is 1366*768, the standard rate drive type has 4098 data lines and 768 scan lines; the double rate drive type has 2049 data lines and 1536 scan lines; the triple rate drive type has 2049 data lines and 1536 scan lines; The driving type has 1366 data lines and 2304 scanning lines. [0003] When the data signal charges the pixels of the display panel through the data line, due to the existence of impedance, the charging time of the data signal to adjacent pixels is different, resulting in insufficient charging rate of some pixels, and vertical bright and dark lines appear on t...
