Problems solved by technology

[0004] Please refer to Fig. 3 again, it is the patent of U.S. Patent Publication No. (USPN) No. 5,969,850 announcement, and as can be seen from the aforementioned comparison, it removes one carrier plate 6 of the liquid crystal display 4, shortens the object distance d, so that the viewing distance D reaches about 35 cm, although it can meet the application range of small and medium-sized displays, it must carry out multiple processes such as coating, etching, and rubbing on both sides of the carrier 6. Obviously, it is different from the current There are considerable differences in the panel manufacturing process that only performs plating, etching, and alignment on one side of the carrier plate 6, so its production cost is quite high, which obviously does not meet the needs of mass production.

Embodiment Construction

[0024] In order to have a deeper understanding and recognition of the features, purposes, and effects of the present invention, the preferred embodiments are now listed and described in conjunction with the accompanying drawings as follows:

[0025] Please refer to FIG. 4 , which is a structural diagram of the first embodiment. The parallax barrier 20A is arranged on the outside of the display device 30. The parallax barrier 20A is arranged in sequence from the inside to the outside with a second polarizer 24 and a second carrier 23. , a liquid crystal layer 25, a first polarizer 21, and a first carrier plate 22, the first carrier plate 22 and the second carrier plate 23 have electrodes with specific patterns on one side near the liquid crystal layer 25 (not shown in the figure As shown), the two surfaces in contact with the liquid crystal layer 25 have undergone alignment treatment, and its function is to make the liquid crystal molecules of the liquid crystal layer 25 present...

Abstract

This invention disclose a display system capable of converting plane / stereo images including a display device and a parallax fence, which can be converted to a total penetration mode so as to convert the stereo images to plane images. This invented parallax fence is composed of a torsion nematic obstructor, a diffuser is set inside of carry plate replaced by a plastic base, so that the distance between the visual position of the fence and the display pixel of the display device is rather short to provide a shorter stereo image distance.

Description

technical field [0001] The present invention relates to a display system of stereoscopic images, in particular to a display system of convertible plane / stereoscopic images using a parallax barrier. Background technique [0002] Please refer to Fig. 1, which is a patent issued by US Patent Publication No. (USPN) No. 6,108,029, which discloses a display system capable of converting plane / stereo images. The backlight module 1 and the parallax barrier 2 are respectively placed on the display device. 3 (transmissive panel) on both sides, the parallax barrier 2 has two modes, such as a full transmissive mode (Transmissive Type) and a barrier (Barrier) mode, and the parallax barrier 2 is controlled by a switch 12, so that the parallax barrier 2 can Switch freely between the two modes of penetration mode and fence mode to convert plane images and stereo images. [0003] Please refer to FIG. 2 again, the display device is a liquid crystal display 4 (Liquid Crystal Display; LCD) with...
