Although a naked-eye 3D display is more convenient to watch for a viewer, so far and in the near future the image quality of a stereo display watched with special glasses is still much better than the former. e.g. the viewing angle, the crosstalk, the resolution, etc. While focusing on the glasses-type stereo display, the image performance of a time multiplexed shutter-glasses-type 3D display should be better than that of a spatial multiplexed polarization-encoded 3D display. Shutter-glasses-type 3D display was implemented many years ago by CRT. However, due to the generation supersedure the CRT was replaced by LCD, the shutter-glasses solution couldn't work for several years as a result of the long response time of LCD. Thanks to the development of over-drive technology, the response time of LCD is getting faster, and a 100-120Hz panel refresh rate is possible. Therefore, 3D game fans have a very good opportunity to watch full resolution, large viewing angle and low crosstalk stereo LCDs again. In this paper, a 120Hz LCD and an LED dynamic backlight to overcome the hold-type characteristic of an LCD are used to implement a time-multiplexed 3D display. A synchronization circuit is developed to connect the time scheme of the vertical sync. signal from the display card, the scanning backlight and the shutter glasses. The crosstalk under different scanning conditions is measured.
