Abstract:
1. An autostereoscopic display comprising: a light source; a display panel which forms an image by controlling the transmittance of light incident from the light source, the display panel being scanned in a vertical direction thereof; a display panel controller which controls the modulation of the display panel and scans the display panel according to an image signal; a switching barrier which separates the viewing zone of an image beam incident from the display panel by electrically controlling light transmittance and which includes odd column cells and even column cells that are alternately arranged in a horizontal direction and are alternately switched between slits which transmit light and masks which block light, the switching barrier comprising: a first electrode connected to the odd column cells; a second electrode connected to the even column cells; and common electrodes respectively connected to n regions that are arranged in the vertical direction of the switching barrier; and a switching barrier controller which controls barrier modes of the slits and the masks to be changed in synchronization with the scanning of the display panel.
