Abstract:
1. An autostereoscopic 3D display device, comprising: a display panel for displaying an image; a backlight to provide light to the display panel; and a switching panel attached to the display panel for selectively implementing a 3D image mode and a 2D image mode according to whether an electric signal is supplied, the switching panel being divided into a transmission region and a non-transmission region, the switching panel comprising: a glass substrate; a transparent electrode layer formed on an entire surface of the glass substrate; electrochromic material pattern portions repetitively formed at regular intervals on the transparent electrode layer to define non-transmission regions and transmission regions, the non-transmission regions being respectively formed of portions of the transparent electrode layer with the electrochromic material pattern portions thereon, the transmission regions being respectively formed of portions of the transparent electrode layer without the electrochromic material pattern portions thereon, the electrochromic material pattern portions being doped with conductive materials such that the electrochromic material pattern portions having the conductive materials change color in accordance with the electric signal, and the non-transmission patterns obtain a desired color by an electric current; and a single non-transmission pattern connecting line formed along an outer edge of the glass substrate in a first direction, to electrically connect only one common side of the electrochromic material pattern portions and to supply the electric signal to the electrochromic material pattern portions, wherein each of the electrochromic material pattern portions extend in a second direction from the single non-transmission pattern connecting line; wherein, when the electric signal is supplied to the electrochromic material pattern portions, the switching panel implements an autostereoscopic 3D display device, and wherein, when the electric signal is not supplied to the electrochromic material pattern portions, the electrochromic material pattern portions become transmitting to display a 2D image.
