Patent ID: 8115985

Claim:
A 2D/3D display device, comprising: a flat display device; and a parallax barrier panel disposed on a display surface of the flat display device, the parallax barrier panel comprising: a transparent substrate; a transparent conductive layer disposed on a surface of the transparent substrate; and a barrier pattern dispose on the transparent conductive layer, the barrier pattern comprising a first electrochromic material layer, a first transparent electrode, a second electrochromic material layer, and a second transparent electrode subsequently disposed on the transparent conductive layer; wherein the parallax barrier panel is switched between a 2D display mode and a 3D stereoscopic display mode, the barrier pattern is a transparent pattern when the parallax barrier panel is in the 2D display mode, and the first electrochromic material layer and the second electrochromic material layer are transparent when the parallax barrier panel is in the 2D display mode.
