Abstract

The embodiment of the invention discloses a display device and a driving method of the display device. The display device comprises a plurality of driving chips, wherein the number of the data lines electrically connected with at least a part of the driving chips is different; the line synchronization signal periods of the driving chips are the same, and the time lengths of the effective synchronization pulse stages are the same. According to the display device provided by the embodiment of the invention, when the numbers of the lines electrically connected with the different driving chips aredifferent, the line synchronization signal periods of the driving chips are the same.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display device and a driving method for the display device. Background technique [0002] At present, display technology is widely used in televisions, mobile phones, advertising information, and vehicles. In display products such as display devices used for displaying advertisement information or display devices used in vehicle displays, they are generally large-sized display products. In large-size display products, because of the large screen, the load is relatively large, and it is often not enough to drive the display panel to display through the driving capability of one driver chip. Therefore, multiple driver chips are usually used for driving, that is, different The driver chips are respectively electrically connected to the data lines in the display panel. [0003] However, when the number of data lines electrically connected to different ...
