ABSTRACT:
A dual-mode display system for 2D viewing and includes an image display device and an LCD panel. The image displaying device is used to show a regular 2D image for 2D viewing and to show an interleaved image composed from a right view and a left view of a scene for 3D viewing. The LCD panel having a plurality of linear sections is used to form a parallax barrier for 3D viewing. The same LCD panel can be turned off so that all the linear sections are clear to transmit light for 2D viewing. The image displaying device can be transmissive type and the LCD panel can be placed behind or in front of the displaying device. Preferably, a large-area illuminator is used to provide illumination to the transmissive displaying device. The image displaying device can also be emissive type and the LCD panel must be placed in front of the displaying device.
