A newly developed liquid crystal display‐generated (LCD‐generated) parallax barrier method for an autostereoscopic three‐dimensional (3‐D) display is described. This system consists of two LCD panels constituting a 3‐D display and a slit barrier. Compared to a conventional parallax barrier method, the slit barrier is not fixed but variable electrically. Therefore, the method can be flexible for any desired multiviewpoint 3‐D image display system. The compatibility with the usual 2‐D image display is fully ensured. Also, both 2‐D and 3‐D images can simultaneously be displayed. A prototype 3‐D image display apparatus suitable for a personal computer has been demonstrated to indicate a strong feasibility for a new 3‐D image display application.
