We propose 2D/3D convertible display system with enhanced 3D viewing angle based on integral imaging. We use 3 LCD devices and a lens array in the proposed system. The LCD device 1is used for displaying an elemental image which turn into a 3D image through the lens array. The LCD device 2 is used as a polarization switcher to control the transparent and the opaque region of elemental image. The LCD device 3 is used as both mask pattern and 2D image displaying device. On the back glass of LCD device 3, we attach polarization-selective scattering film which makes LCD device 3 used as a mask pattern and a 2D display device at the same time. Behind of the LCD device 3, the lens array is located for displaying 3D image by the integral imaging method. The whole system is as compact as conventional integral imaging system. With the LCD device 2 and 3, the viewing angle of 3D image can be enhanced both vertically and horizontally according to the arrangement of elemental image. We prove the feasibility of proposed system by basic experiments.
