摘要： Provided is a highly efficient two-dimensional (2D)/three-dimensional (3D) image switchable stereoscopic display (30). The stereoscopic display apparatus (30) includes: a backlight unit (31) which has a reflective plate (37) disposed on a bottom surface thereof; a polarizer (32) which only transmits light of a specific polarization direction emitted from the backlight unit (31); a first birefringent element array (33) including a plurality of alternating first and second birefringent elements (33a,33b) that change the polarization direction of incident light; a second birefringent element array (34) including a plurality of alternating third and fourth birefringent elements (34a,34b) that change the polarization direction of incident light; a reflective polarizing sheet (35) which transmits light of a specific polarization direction transmitted by the second birefringent element array (34) while reflecting light of another polarization direction transmitted by the second birefringent element array (34); and a display panel (36) which displays an image.

摘要： An autostereoscopic display is provided which includes: a light source; a display panel which forms an image by controlling the transmittance of light incident from the light source; a display panel controller that controls the modulation of the display panel and that scans the display panel according to an image signal; a switching barrier that 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 transmitting light and masks blocking light; and a switching barrier controller that controls barrier modes of the slits and the masks to be changed in synchronization with the scanning of the display panel.
