Orthogonal-polarized directional backlight-based three-dimensional display with high horizontal resolution and low crosstalk

An orthogonal-polarized directional backlight-based three-dimensional (3D) display is proposed. This backlight consists of an orthogonal-polarized backlight and a parallax barrier, so it can project light with different polarized directions to different spatial directions. The backlight can project the pixels with different polarized directions on the two-dimensional display in different directions and form 3D images. With this backlight, the proposed display can provide double horizontal resolution. A prototype of this display is developed. Experiment results show that this display with double horizontal resolution can provide a better display effect than the conventional one, and it can decrease crosstalk to a low level.
