Abstract

The invention relates to a display device. A display panel comprises scanning lines, data lines, pixel units and active array switches. The scanning lines comprise 2n pairs of first scanning lines anda plurality of pairs of second scanning lines; The active array switches comprise first active array switches and second active array switches; The drain electrode of each first active array switch is connected with a corresponding pixel unit arranged between each pair of first scanning lines, the grid electrode of each first active array switch is connected with a corresponding first scanning line, and the source electrode of each first active array switch is connected with a data line; The drain electrode of each second active array switch is connected with a corresponding pixel unit arranged between each pair of second scanning lines, the grid electrode of each second active array switch is connected with a corresponding second scanning line, and the source electrode of each first active array switch is connected with a data line; The ratio of the channel width to the channel length of the first active array switch is greater than the ratio of the channel width to the channel length of the second active array switch.

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...
