Device and driving method thereof

摘要

To provide a display device and its driving method free from lack of writing time, which usually accompanies an increase in size of a display device and enhancement in definition. Therefore, there is provided a display device and a driving method in which x (x is a natural number equal to or larger than 4) data lines are placed in each column to simultaneously supply video signals to x pixels through the x data lines. The present invention makes it possible to supply video signals to x pixels simultaneously as opposed to conventional dot sequential driving where a signal is supplied to one pixel at a time. Furthermore, a display device of the present invention and its driving method make it possible to supply video signals to (xxn) pixels at once as opposed to conventional linear sequential driving where only n pixels in the first to last (the last column is the n-th column) columns receive signals simultaneously. Thus the present invention can make the speed of writing video signals in pixels x times faster than prior art.
