Abstract

An autostereoscopic display apparatus includes a backlight unit, a polarizing plate disposed in front of the backlight unit; a display panel displaying a left eye image and a right eye image by interlacing pixel lines of the left and right eye images alternately and sequentially; a lenticular lens sheet, disposed between the polarizing plate and the display panel, separating light emitted from the backlight unit into a left eye zone and a right eye zone; and a polarization switch controlling a polarization direction of light proceeding towards the left eye viewing zone so that light is incident on pixel lines of the display panel displaying the left eye image and a polarization direction of light proceeding towards the right eye viewing zone so that light is incident on pixel lines of the display panel displaying the right eye image, in synchronization with a vertical scanning time of the display panel.

Description

technical field [0001] Apparatus consistent with the present invention relates to a high-resolution autostereoscopic display, and more particularly to a high-resolution autostereoscopic display with no reduction in resolution and no crosstalk when displaying images in an interlaced method. Stereoscopic display device. Background technique [0002] The autostereoscopic display device is for displaying an image for the left eye and an image for the right eye exhibiting binocular parallax to the left and right eyes of the viewer, respectively. A viewer can recognize a left-eye image and a right-eye image provided by the autostereoscopic display device through the retinas of both eyes, thereby seeing a 3D image. Autostereoscopic display devices include devices using a parallax barrier method and devices using a lenticular method. [0003] According to the parallax barrier method, images to be seen by left and right eyes are alternately displayed in a vertical mode, and the dis...
