20110063533METHOD OF DISPLAYING STEREOSCOPIC IMAGES MIXED WITH MONOSCOPIC IMAGES AND MONO/STEREOSCOPIC IMAGE DISPLAY APPARATUS CAPABLE OF PERFORMING THE METHOD - An image display apparatus is provided that can display one or both of 2D imagery and 3D imagery in respective but randomly selectable display areas of the apparatus. The apparatus a display panel, a driving circuit part, a polarization switch panel and a lens. The driving circuit part processes received frame image data representing two-dimensional (2D) imagery and three-dimensional (3D) imagery to thus provide the display panel with the processed frame image. The polarization switch panel is disposed above the display panel. The polarization switch panel is switched into a first polarization mode in correspondence with 2D imagery being displayed by the display panel and it is switched into a second polarization mode in correspondence with 3D imagery being displayed by the display panel. The lens is reacts differently to light rays having the effect of the first polarization mode imparted to them and to light rays having the effect of the second polarization mode imparted to them. More specifically, the lens strongly refracts light rays that are imparted with the second polarization mode (3D imagery light) and weakly or not at all refracts light rays that are imparted with the first polarization mode (2D imagery light). Thus, both the 2D image and the 3D image may be displayed on one screen.03-17-2011
