Embodiment Construction
[0030] 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.
[0031] 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...

The invention relates to a method for improving vertical bright and dark lines of a display panel and a device thereof. The device comprises the display panel, an ordering module, a scanning signal driving module and a data signal driving module; the display panel comprises a plurality of pairs of scanning lines, a plurality of data lines and a plurality of pixel units; the plurality of pairs of scan lines are arranged in a row direction; the plurality of data lines are arranged in a column direction; the plurality of pixel units are arranged between each pair of scan lines and arranged in a matrix, and each adjacent two columns of pixel units share a data line, the pixel unit sharing one data line is connected to different scan lines, and each column of pixel units is a pixel of the samecolor, and the pixel unit is regularly arranged in six columns; the ordering module is configured to change a color arrangement sequence of each adjacent six columns of pixel units to a preset sequence; the scanning signal driving module is configured to input a scan pulse signal to the scan lines; and the data signal driving module is used to input a square wave data signal to the data line to improve vertical bright and dark lines on the display panel.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a method and device for improving vertical bright and dark lines of a display panel. 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 ...
