Abstract:
1. A three-dimensional (3D) image display device, comprising: a display panel displaying an image; a lens panel positioned on the display panel, the lens panel comprising: a lens panel driver supplying a first driving voltage to the first electrode and a second driving voltage to the second electrode of the lens panel; responsive to one of the first driving voltage or the second driving voltage swinging from a first potential to a second potential, the other driving voltage is maintained at a potential equal to the first potential during a 3D mode of the 3D display device or the other driving voltage is maintained at a potential equal to the second potential during a two-dimensional (2D) mode of the 3D display device; wherein during the 3D mode of the 3D display device, the lens panel driver generates a voltage difference in the first driving voltage and the second driving voltage by outputting the first driving voltage at the first potential and the second driving voltage at the second potential and switching by a frame unit of at least N, where N is an integer of 1 or greater, to outputting the first driving voltage at the second potential and the second driving voltage at the first potential; wherein a refractive index of the lens layer and a refractive index of the electrolyte layer are varied according to the first driving voltage and the second driving voltage supplied to the lens panel.
