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 present application relates to a display device, including a display panel, a scanning signal driving module, and a data signal driving module; the display panel includes scanning lines, several data lines, pixel units, and a black matrix; the scanning lines include 2n pairs of first scanning lines and several For the second scanning line; the pixel units are arranged between each pair of scanning lines and arranged in a matrix; the black matrix is ​​arranged on the surface of the pixel units between each pair of first scanning lines to block the light emission of the pixel units; scanning signal The driving module is used to simultaneously input the scan pulse signal to the scanning line connected to the Nth pixel unit and the scanning line connected to the N+4nth pixel unit; the data signal driving module is used to input a square wave data signal to the data line , to charge the Nth pixel unit and the N+4nth pixel unit sharing one data line, so as to improve the vertical bright and dark lines on the display panel.

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...
