The moiré pattern is caused by the spatial interference of two regular pattern structures. In the case of an
autostereoscopic display, it's caused by the overlap of the parallax barrier and the black matrix among pixels of FPD. To
minimize the moiré effect, we simulate the relationship of brightness distribution and various design parameters of the
parallax barrier. According to the simulation results, a combination of multiple parameters was chose to obtain a moiré
free autostereoscopic display based on the concept of mutual compensation among the design parameters. After the
detailed simulation, experiments of the final design were made to verify the performance of the display.
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.
