Problems solved by technology

[0006] The above-mentioned parallax barrier method, when originally invented, had the following problem: since the parallax barrier is arranged between the pixels and the eyes, it becomes an eyesore and results in low visibility
In particular, because the lenses are two-dimensionally arranged in the fly-eye lens, bright and dark banded images intersect two-dimensionally, and bright and dark grainy images appear on the displayed image, thereby reducing the display quality

Embodiment Construction

[0043] Because in the existing three-dimensional image display device of the lenticular method, the striped figure on the chassis is seen and overlaid on the display image, so that the quality of the display image recognized by the viewer is reduced and thus This strip pattern becomes an eyesore in image observation. Then, the inventors of the present invention put themselves into research on the lens pitch L of the cylindrical lens of the double-sided lens and the visibility of the band pattern appearing on the three-dimensional image, and found that when external light is reflected on the lens surface , you will see a ribbon graph.

[0044] The total width of the bright and dark portions of the stripe pattern is equal to the lens pitch L of the cylindrical lenses, and the width of each of the bright and dark portions varies according to the characteristics of external light. Figure 5A is a standard view showing the reflection of light at the surface of the lens when the ext...

Abstract

A three-dimensional image display device is provided with a liquid crystal display panel, where a plurality of pixels for the right eye displaying an image for the right eye and a plurality of pixels for the left eye displaying an image for the left eye are arrayed, and a lenticular lens that is arranged on a side of the liquid crystal display panel, which faces a viewer, and whose surface facing the liquid crystal display panel is flat and surface facing the viewer has a plurality of hog-backed cylindrical lenses formed thereon so as to be parallel with each other, in which the lens pitch of the cylindrical lenses of the lenticular lens is set to 0.2 mm or less.

Description

technical field [0001] The present invention relates to a three-dimensional image display device and a portable terminal device including an optical unit basically including a plurality of lenses such as a double-sided lens and a fly-eye lens, and a double-sided lens, and particularly relates to a A three-dimensional image display device, a portable terminal device, and a double-sided lens, wherein a banded figure generated by the shape of the lens does not appear in a three-dimensional image recognized by a viewer, thereby improving display quality. Background technique [0002] Conventionally, display devices capable of displaying three-dimensional images are being studied. Regarding binocular vision, in 280 BC, the Greek mathematician Euclid (Euclid) believed that "binocular vision is the feeling obtained when the right eye and the left eye watch different images of the same object from different directions at the same time" (Refer to the first page of the document "Thre...
