Abstract

The invention discloses a method for driving a display device. The display device comprises scanning lines, data lines, pixels, a first source driving circuit and a second source driving circuit, wherein the scanning lines are sequentially positioned in a first region, a middle region and a second region; and each data line is divided into two line segments which are electrically disconnected with each other. The method for driving the display device comprises the following steps of: simultaneously conducting one of the scanning lines in the first region and one of the scanning lines in the second region; supplying data to the pixels electrically connected to the conducted scanning line in the first region from the first source driving circuit through the data lines, and supplying data to the pixels electrically connected to the conducted scanning line in the second region from the second source driving circuit through the data lines; scanning all the scanning lines in the first region and the second region, and then conducting one of the scanning lines in the middle region; and supplying data by the first source driving circuit or the second source driving circuit according to positions of the two electrically disconnected line segments of each data line.

Description

【Technical field】 [0001] The present invention relates to the technical field of display devices, in particular to a driving method of a display device. 【Background technique】 [0002] see figure 1 , which is an existing display device 10, the display device 10 includes several scanning lines 100 (also called gate lines), several data lines 102 (also called source lines) and several pixels 104, each pixel 104 is controlled to be on or off by a corresponding scan line 100 and data is provided by a corresponding data line 102 . [0003] The driving method of the traditional display device 10 is to turn on one scanning line 100 sequentially from top to bottom, and then write data into the pixels 104 controlled by the turned-on scanning line 100 through the data line 102, that is to say, the traditional driving method One scan line 100 is turned on at a time, and the first scan line 100 is driven sequentially after the last scan line 100 is turned on. [0004] In order to spe...
