Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a three-dimensional display device in which display patterns with different liquid crystal alignment treatments are formed within the same liquid crystal display panel.

Conventional configurations and their problems In recent years, the development of display devices such as video devices has been very active, and remarkable progress has been made in various fields. The demand for this is increasing.

Conventional stereoscopic image display devices are optically decomposed into line images at the imaging station and directly sent and received by the television system. By aligning the lenticular plate with the reproduced line image on the monitor screen, the reproduced stereoscopic line image can be observed with the divine eye. In this case, there was a problem in that the image was observed in a striped manner and was very unsightly.

Another example is an image ★6\. from a different direction on a monitor TV. ．． There is a system in which the transmission is performed alternately at about OHZ level, and a chanotar mechanism is provided in front of the observer's eyes for the left and right eyes at the same frequency as the frequency of the Hara transmission. In this case, there was a problem that the striped image could not be observed (flickering of the display was very noticeable).

OBJECTS OF THE INVENTION It is an object of the present invention to completely eliminate these conventional drawbacks and provide a completely new stereoscopic display device using liquid crystal that consumes very little power.

Structure of the Invention In order to achieve this object, the stereoscopic display device of the present invention forms display patterns with different liquid crystal alignment treatments in the same liquid crystal display panel, and one of them is a left-eye pattern,
The other one is a right-eye putter/binder, and the three-dimensional image can be viewed simultaneously with the left and right eyes, respectively.

With this configuration, it is possible to see a three-dimensional image that is easy to see without striped images or flickering.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a three-dimensional display device according to an embodiment of the present invention using a twisted nematic type liquid crystal. In FIG. 1, 1 and 2 are polarizing devices having windows, 3 and 4 are transparent substrates having electrodes, and 6 is a twisted nematic type liquid crystal layer.

FIG. 2 is an exploded perspective view showing the principle of the stereoscopic display device. In FIG. 2, 11L and 2a are the windows of the polarizers 1 and 2, respectively, 6 and 7 are arrows indicating the vibration directions of the transmitted light in the polarizers 1 and 2, respectively, and 8 and 9 are the transparent substrates 3.
10.11 is an arrow indicating the rubbing direction of the upper surface of the transparent substrate 4, 12.13 is a display pattern, 14.15 is a polarizing device on the viewer's side, 16.
17 are arrows indicating the vibration directions of the transmitted light in the polarizers 14 and 15, respectively.

According to such a stereoscopic display device, a display pattern 12 oriented in the directions of arrows 8 and 10 and a display pattern 13 oriented in the directions of arrows 9 and 11 are formed in the same liquid crystal display panel, and the display pattern 12 is oriented in the directions of arrows 9 and 11. A polarizing device 2 that transmits light vibrating in the direction of the arrow 6 is installed on the upper and lower surfaces of the pattern 12, and a polarizing device 1 that transmits the light that vibrates in the direction of the arrow 6 is installed on the upper and lower surfaces of the display pattern 13. Therefore, a polarizer 14 that transmits light vibrating in the direction of arrow 16, which is the same direction as arrow 7, is installed in front of the observer's left eye, and a polarizer 14 that transmits light that vibrates in the direction of arrow 17, which is the same direction as arrow 6, is installed in front of the observer's right eye. Polarizing device 15'fr that transmits light: When installed, the pattern displayed by the display pattern 12 cannot be observed with the right eye because the lights are always orthogonal, but it can be observed with the left eye because the light vibrating in the same direction is transmitted. can. Similarly, the pattern displayed as display pattern 13 cannot be observed with the left eye, but can be observed with the right eye. That is, when the left-eye pattern is displayed on the display turn 712 and the right-eye pattern is displayed on the display turn 13, the observer simultaneously observes the left-eye pattern with his left eye and the right-eye pattern with his right eye. You can see 3D images.

In the above embodiment, a twisted nematic type liquid crystal was used for the liquid crystal layer, but the guest. Host type (7) Liquid crystal'
By using this method, you can view a 3D image simply by installing a polarizer that transmits light perpendicular to the alignment direction of the liquid crystal on at least one of the top and bottom surfaces of the liquid crystal display. It was confirmed through experiments that this device can be used.

Effects of the Invention As described above, the stereoscopic display device of the present invention has a structure in which display patterns with different liquid crystal alignment treatments are formed in the same liquid crystal display panel, so that the pattern for the left eye on one side and the pattern for the right eye on the other side are formed. : displayed and can be viewed simultaneously with the left and right eyes, respectively, allowing you to see a 3D image without flickering and without image unevenness. 1. Because images observed from different directions can be reproduced in the same place,
You can view stereoscopic images more naturally. Since it is composed of a single-layer liquid crystal display panel, it is possible to have a thin and compact structure, which is of great industrial value in the field of liquid crystal display, which will continue to develop.
