Patent ID: 8860659

Claim:
A display apparatus for displaying two-dimensional /three-dimensional (2D/3D) images comprising: a display panel; and a parallax barrier plate including a plurality of parallax barrier cells, wherein each of the parallax barrier cells comprises: a receiver; a plurality of charged pigment particles filled in the receiver; and a switch electrode disposed at one side of the receiver for driving the charged pigment particles to move, wherein the charged pigment particles are dispersed in the receiver when the display apparatus is in a 3D image displaying mode, and the switch electrode is electrically connected to a voltage for driving the charged pigment particles to move toward the inner sidewall of the receiver; wherein the parallax barrier plate includes a first parallax barrier layer and a second parallax barrier layer, and the second parallax barrier layer is disposed between the display panel and the first parallax barrier layer for reflecting the light from the display panel; wherein the first parallax barrier layer comprises the plurality of charged pigment particles, and the second parallax barrier layer comprises a plurality of charged reflection particles, and the first parallax barrier layer and the second parallax barrier layer are transparent when the display apparatus is switched to a 2D image displaying mode.
