Abstract: A gate driving unit connected to odd-numbered gate lines and a gate driving unit connected to even-numbered gate lines are sequentially operated, and a common voltage signal is inverted when the operation states of the two gate driving units are changed, thereby minimizing a number of changes in the voltage level of the common voltage signal supplied to a display panel during one frame, reducing power consumption of the display device, and allowing pixels of the display panel to perform line inversion.

Abstract: The present invention relates to a three-dimensional (3D) pen with a novel structure which enables filaments having various colors to be easily selected and used. According to the 3D pen according to the present invention, a user laterally rotates the adjustment lever (25) to allow the driving motor (24) to be connected to different transfer rollers (22), thereby selectively transferring and discharging a plurality of different filaments (1) forward. Therefore, the 3D pen has a very simple structure and has an advantage in that the filaments (1) having various colors can be easily selected to manufacture objects having various colors.
