Abstract

PROBLEM TO BE SOLVED: To provide a three-dimensional image display device which has high definition and more pixels. SOLUTION: The lights emitted by a light source array 1 having light emission diodes(LED) arrayed longitudinally and laterally on a plane are transmitted through a liquid crystal display element 2 consisting of a polarizing plate and a liquid crystal layer. At this time, the pixels of the liquid crystal display element are spatially modulated with three-dimensional image data, so a group of modulated light beams is made incident on both the eyes of an observer, so that a stereoscopic image is recognized. Lights from the LEDs which illuminate at certain intervals pass through, for example, three pixels (nine pixels in two dimensions) of the liquid crystal display element 2, so that light beams a1 to a10 form one image. Alternate LEDs are made to illuminate and then alternate pixels of the liquid crystal display element are moved to, thereby forming a new screen. a sequence of operations like this is performed fast enough to obtain after-image effect and the gaps of the light beams a1 to a10 are filled with light beams (b1 to b10) and (c1 to c10) to obtain stereoscopy.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a three-dimensional image display device, and more particularly to a multi-view type three-dimensional image display device.

[0002]

2. Description of the Related Art FIG. 12 is a view for explaining a conventional three-dimensional image display system of a two-lens system. The structure and operation thereof will be described. A fine slit is provided in front of a display element 81 such as a liquid crystal display element. Are arranged in a one-dimensional lattice at a small pitch in parallel with each other, and a slit lattice 82 called a “parallel barrier” is provided slightly apart from the display element 81.

When an observer 83 looks in the direction of the paralags barrier 82 with the right eye from a predetermined observation position, an image I for the right eye, which is a set of strip images, is passed through the parallax barrier 82.
R is observed. Similarly, the parallax barrier 82 with the left eye
, The left-eye image IL, which is a set of strip images, is observed via the parallax barrier 82.

At this time, the image IL for the left eye cannot be observed with the right eye and the image IR for the right eye can be observed with the right eye, being blocked by the light shielding portion of the parallax barrier 82. In this state, when viewing the direction of the parallax barrier 82 with both eyes, different images are observed for each eye, and therefore, the images are recognized as a stereoscopic image due to the binocular parallax effect.

[0005] Such a stereoscopic image display system is called a "two-lens system". In this twin-lens system, since a motion parallax (a change in a three-dimensional image due to movement of an observation position) cannot be obtained, the three-dimensional effect is somewhat unnatural. There is also a disadvantage that the observation position is limited to a narrow range. As a stereoscopic display method for realizing the above-described motion parallax, a “multi-view method” is known.

FIG. 13 is a view for explaining a multi-view three-dimensional image display method. A plurality of images corresponding to different positions a, b, c, and d of the eyes of the observer 93 are prepared. Is divided into strips using the parallax barrier 92 and displayed on the image element 91. In this way, the stereoscopic image to be observed changes while realizing binocular parallax according to the movement of the observation position of the observer 93, and a more natural stereoscopic effect is realized as compared with the twin-lens system. Is done.

The multi-view system using the parallax barrier 2 is as follows.
It is also called "Parallax Panoramagram".

[0008]

The multi-view system (paralux panoramagram) improves the stereoscopic effect by increasing the number of images (the number of eyes) changing in accordance with the movement of the observation position in principle. It is a possible method.

However, when a multi-view three-dimensional display device is manufactured using a display element having a certain pixel density, the pitch of the slit lattice of the parallax barrier must be increased with an increase in the number of eyes. , The light-shielding portion of the parallax barrier becomes conspicuous. In order to solve this problem, if the pixel density of the display element is increased, the slit width becomes narrower, so that the light diffraction phenomenon becomes remarkable, and the stereoscopic image becomes blurred. That is,
With this method, it is difficult to realize continuous motion parallax while having high definition.

As described above, the problem that there is a trade-off between increasing the number of multi-views and increasing the definition of a three-dimensional image is not limited to the above-described parallax panoramic gram, but the multi-view lenticular method. The same is applied to the above.

The present invention has been made in view of the above-described circumstances, and provides a three-dimensional image display device which has a high definition, a large number of multi-views, and a continuous motion parallax can be obtained. It is.

[0012]

An array, comprising: an image display unit that spatially modulates the light from the light source array based on three-dimensional screen data in synchronization with the light emitting operation of the light emitting pattern. The number of multi-viewpoints is large, and continuous motion parallax in both vertical and horizontal directions is obtained.

According to a second aspect of the present invention, in the first aspect, the light source array comprises a planar light source and a two-dimensional shutter array.
A two-dimensional light source array capable of achieving the same high definition as the image display unit is provided, and a three-dimensional image with higher definition is obtained.

According to a third aspect of the present invention, in the second aspect of the present invention, an image forming means is provided between the planar light source and the two-dimensional shutter array. In addition to the control, the light use efficiency of the light source is improved by increasing the amount of light directed to the observer.

According to a fourth aspect of the present invention, there is provided a light source array having a plurality of linear light sources arranged in a vertical direction on a plane, and having a predetermined temporal and spatial light emitting pattern. An image display unit that spatially modulates light from the light source array based on three-dimensional image data in synchronization with the light emitting operation of the light emitting pattern. Are large and a more continuous lateral motion parallax is obtained.

According to a fifth aspect of the present invention, in the fourth aspect, the light source array is constituted by a one-dimensional shutter array in which a planar light source and slit-shaped openings are arranged on a plane. Thus, a one-dimensional light source array capable of achieving high definition in the horizontal direction at the same level as the image display unit is provided, and a three-dimensional image with higher definition can be obtained.

According to a sixth aspect of the present invention, in the fifth aspect of the invention, an image forming means is provided between the planar light source and the one-dimensional shutter array. In addition to the control, the amount of light directed to the observer is increased to improve the light use efficiency of the light source.

According to a seventh aspect of the present invention, in any one of the first to sixth aspects of the present invention, the light sources of the light source array include light sources of three primary colors of RGB that are periodically turned on sequentially. Thus, color display in which color separation of an image does not occur at an observation position is realized.

According to an eighth aspect of the present invention, in the fourth aspect of the present invention, each of the liquid crystal spatial modulation elements of the image display unit independently modulates light of three primary colors of RGB arranged in a vertical direction with respect to a viewer. It has three possible regions, so that color display can be performed more easily while preventing color separation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (Invention of Claim 1) FIG. 1A is a sectional view of a main part of a three-dimensional display device according to the present invention, in which 1 denotes an arrangement of light emitting diodes (LEDs) 1a in the vertical and horizontal directions. Done 2
Two-dimensional light source array, two polarizing plates 2a and 2c, a liquid crystal layer 2
b is a liquid crystal display element that constitutes a transmission type image display unit composed of b. FIG. 1B is a diagram showing an LED array of a two-dimensional light source array. These LEDs are numbered from 1 to 9 for explaining multi-view display.

In the case of performing multi-view display with three eyes at the top, bottom, left and right, each of the LEs numbered 1 to 9 in FIG.
An operation is performed to repeat a cycle in which D is sequentially turned on in numerical order. It is desirable that the repetition frequency be as high as possible to reduce flickering to the eyes.
The liquid crystal display element is operated to switch the display screen as if the lighting position of the LED is changed.

This situation will be described with reference to FIGS. 2, 3, and 4 are diagrams illustrating the three-dimensional display device of FIG. 1 in correspondence with the operation of nine eyes, respectively, showing a state where three eyes are displayed laterally to an observer. Represents.

First, in FIG. 2, light emitted at a predetermined divergence angle from each LED of the two-dimensional light source array 1 illuminated at a fixed interval emits light at three pixels (for an observer) Spatial modulation corresponding to three-dimensional image data is performed by the vertical direction, that is, nine pixels in consideration of the direction perpendicular to the paper surface. As a result, three images (nine images in the vertical direction with respect to the observer, that is, nine images in consideration of the direction perpendicular to the paper surface) that are distinguished by the light emitting directions are simultaneously displayed. For example, in FIG. 2, the light beams a1 to a10 constitute one image to be displayed in that direction.

Next, in FIG. 3, the lit LED moves to the next one in FIG. 2, and the liquid crystal display element switches to a new screen in synchronization with this. Assuming that the LED to be lit at this time is, for example, lit in FIG. 2 and the LED is represented by the number “1” in FIG.
This corresponds to the one represented by “2”. As in FIG. 2, in this state, images are displayed in three different directions.

Next, in FIG. 4, the LED to be turned on is
It moves to the position represented by "3" in (B) and switches the display image of the liquid crystal display element to new screen information in synchronization with this. Thus, the position of the LED to be turned on is shown in FIG.
While moving from “1” to “9” in (B), a series of operations of switching the display contents of the liquid crystal display element to those required for multi-view display at each time point are repeatedly performed. By performing such an operation, it is possible to improve the pixel density of an image formed by a group of light rays traveling in a specific direction.

As can be seen from FIGS. 2 to 4, this embodiment uses a three-lens display in the horizontal direction.
In each state, the pixel density of the image in each direction is one third of the pixel density of the liquid crystal display element, as in the conventional multi-lens lenticular or parallax panoramic gram.

According to the first aspect of the present invention, by performing a series of operations (a) to (c) at a speed at which the afterimage effect of the eye can be obtained, for example, the gap between the light beams a1 to a10 can be reduced from b1 to b.
The effective pixel density in the effective row can be improved by filling with light rays 10 and c1 to c10. In this sense, the images displayed in this direction are from a1 to a1
0, b1 to b10, and c1 to c10. At this time, light rays modulated by pixels of different liquid crystal display elements are incident on the two eyes of the observer, thereby realizing binocular parallax, that is, stereoscopic vision. Then, when the observer moves the observation position, as can be seen from FIGS. 2 to 4,
The light rays entering the observer's eyes change, which results in motion parallax.

(Invention of Claim 2) In the method of the present invention, it is desirable that the density of the LED and the pixel density of the liquid crystal display element be the same or approximately the same. When an attempt is made to use a high-resolution liquid crystal display element to obtain an image, the same density of 2 is used.
Implementing a two-dimensional LED array is technically difficult. Therefore, in the second aspect of the invention, a combination of one light source (backlight) and a transmission type two-dimensional shutter array is used as the two-dimensional light source array having the same density as the liquid crystal display element.

FIG. 5 is a sectional view of an essential part of a three-dimensional image apparatus for explaining an embodiment of the second aspect of the present invention.
Is a planar light source, 11b is a polarizing plate, 11c is a liquid crystal layer (transmission type liquid crystal spatial modulation element... Two-dimensional shutter array), and these constitute a two-dimensional light source array 11. 12a and 12
c is a polarizing plate, 12b is a liquid crystal layer, and these constitute a liquid crystal display element 12 which is an image display unit of a three-dimensional image display device.

The configuration of the two-dimensional light source array 11 is almost the same as that of a normal transmission type liquid crystal display device. The difference from the ordinary one is that a two-dimensional light source array 11, a polarizing plate 11 is arranged to face the planar light source 11a, and a liquid crystal layer (transmission type liquid crystal spatial light modulator) is arranged to face the polarizing plate 1b. Since only one polarizer is required in the space between the liquid crystal display element 12 and the two-dimensional light source array 11 which is an image display unit of the three-dimensional display device, the liquid crystal of the two-dimensional light source array is therefore required. The polarizer is not required on the exit side of the spatial light modulator.

In such a configuration, the liquid crystal layer (liquid crystal spatial modulation element) 11c used in the two-dimensional light source array may have the same specifications as the liquid crystal display element 12 constituting the display part of the three-dimensional display device. In this case, the two-dimensional light source array density and the pixel density of the display element are inevitably equal. Therefore, it is easy to improve the quality of a three-dimensional image by using a high-definition display element.

According to a third aspect of the present invention, a lens is disposed between the light source (backlight) and the two-dimensional shutter array (a liquid crystal spatial light modulator) according to the second aspect of the present invention. By forming a real image on the observer side,
The divergence angle of light emitted from each pixel of the liquid crystal spatial modulation element is controlled, and the amount of light directed toward the observer is increased.

FIG. 6 shows a three-dimensional image display apparatus according to an embodiment of the present invention in which the divergence angle of light emitted from each pixel of the liquid crystal spatial modulation element is controlled to increase the amount of light directed toward the observer. It is a principal part explanatory drawing, In the figure, 21 is a light source, 22 is a Fresnel lens, 23 is a two-dimensional liquid crystal spatial modulation element, 24
Is a liquid crystal display element, and 25 is an observer.

A Fresnel lens 2 is disposed between a light source (backlight) 21 and a two-dimensional shutter (liquid crystal spatial light modulator) 23.
2 and a solid line of the light source 21 is formed on the viewer 25 side via the liquid crystal display element 24.

As can be seen from FIGS. 2 to 4, when the divergence angle of the light emitted from one of the light sources in the light source array is larger than necessary, light rays other than those shown in the drawing are unnecessary in displaying a three-dimensional image. It becomes a ray. However, since this light ray is outside the reproduction area of the three-dimensional image, it is not observed as long as the three-dimensional image is observed. The presence of such a light beam indicates that the light of the light beam (backlight) is not being used effectively.

If an optical system is formed such that a real image of the light source 21 is formed at a predetermined magnification through the lens 22, unnecessary light rays can be effectively removed. In an optical system in which three polarizing plates are inserted as in the embodiment of the second aspect of the present invention shown in FIG. 5, light absorption is increased, and it is important to effectively use light in this manner. It is.

(Invention of Claim 4) The invention described above is
Although a three-dimensional image display is performed by giving a parallax image in both vertical and horizontal directions to the observer, since the human eyes are arranged in the horizontal direction, it is not possible to obtain a stereoscopic effect only with the horizontal parallax image. It is possible. Eliminating the vertical parallax information in this manner has the effects of reducing the amount of information required for reproducing a three-dimensional image and simplifying the configuration of the device. Therefore, in the invention of claim 4, the light source array is a one-dimensional array of linear light sources, so that parallax in the vertical direction is removed, and the above-mentioned effect is obtained.

FIG. 7A is a sectional view of a main part of a three-dimensional image display device in which a light source array is a one-dimensional array.
1 is a one-dimensional (LED) array in which linear light sources 31a extending in the vertical direction are arranged in the horizontal direction, and 32 is polarizing plates 32a and 3
2c, a liquid crystal display element 32 constituting an image display section composed of a liquid crystal layer 32b. FIG. 7B is a diagram showing an array in which the linear light sources 31a are arranged in the horizontal direction.

The operation of the three-dimensional image display device is the same as the operation of displaying a parallax image in the horizontal direction (FIGS. 2 to 4).
In the one-dimensional (LED) array shown in FIG. 7, while repeating the operation of sequentially lighting the numbers from 1 to 3,
The display content of the liquid crystal display element is switched.
As a result, it is possible to display a higher-resolution horizontal parallax image as compared with a conventional multi-view lenticular or parallax panoramic gram.

(Invention of claim 5) Also in the invention of claim 4, if a high-definition liquid crystal display element is to be used, the above-mentioned density of the one-dimensional light source array becomes a technical problem. Therefore, in the invention of claim 5, the one-dimensional light source array is realized by a combination of a slit-shaped one-dimensional shutter array (one-dimensional liquid crystal spatial modulation element) and one light source.

FIG. 8 is a sectional view of a main part of a three-dimensional image display device in which a one-dimensional light source array is combined with a slit-like one-dimensional shutter array (one-dimensional liquid crystal spatial modulation element) and one light source. Is a planar light source, 41b is a deflecting plate, 41
c is a liquid crystal layer (one-dimensional liquid crystal spatial modulation element: slit-shaped 1)
A one-dimensional light source array 41 is constituted by these components, and a reference numeral 42 denotes a liquid crystal display element constituting an image display unit including polarizing plates 42a and 42c and a liquid crystal layer 42b.

The operation of the fifth aspect of the present invention is the same as that of the third aspect of the present invention. By using the one-dimensional liquid crystal spatial modulation element, the same density as that of the liquid crystal display element can be obtained. Thus, a high-definition three-dimensional image can be displayed by using a high-definition liquid crystal display element.

(Invention of claim 6) According to the invention of claim 6, a lens is arranged between the light source (backlight) and the one-dimensional shutter array (one-dimensional liquid crystal spatial modulation element) in the invention of claim 5, By forming a real image of the light source on the observer side, it is possible to control the divergence angle of light emitted from each slit-shaped opening of the one-dimensional liquid crystal spatial modulation element and to increase the amount of light directed toward the observer. It was done.

FIG. 9 shows an embodiment of the three-dimensional image display apparatus according to the sixth aspect of the present invention, which suppresses the divergence angle of light emitted from each pixel of the liquid crystal spatial light modulator and increases the amount of light directed toward the observer. In the figure, 51 is a light source, 52 is a Fresnel lens, 53 is a one-dimensional liquid crystal spatial modulation device, 54 is a liquid crystal display device, and 55 is a viewer.

The operation of the three-dimensional image display device is basically the same as that of the device according to the third aspect of the present invention. As a result, the same effect as that of the third aspect can be obtained in a system using only the horizontal parallax.

Next, the colorization of the three-dimensional image display device according to the present invention will be considered. The simplest means for colorization is to use an image display unit in which pixels for independently modulating the three primary colors of RGB are arranged. However, when the light source is white, the light flux transmitted through each of the RGB pixels in the image display unit is enlarged at the observation position, and a phenomenon called color separation occurs.

(Invention of Claim 7) Therefore, in the invention of Claim 7, color display by time division is performed by periodically changing the wavelength of the light source.

FIG. 10 is a sectional view of a main part of a three-dimensional image display apparatus for performing colorization according to an embodiment of the present invention. In FIG. 10, reference numeral 61 denotes a color light source of three primary colors, and 62 denotes a diffusion plate. ,
63 is a Fresnel lens, 64 is a liquid crystal spatial modulation element, 65
Is a liquid crystal display element capable of only monochrome intensity modulation.

The light emitted from the three primary color light sources 61 is
Diffusion plate 62, Fresnel lens 63, liquid crystal spatial modulator 6
After 4, the image is displayed on the liquid crystal display element 65. The basic operations of the liquid crystal spatial modulation element 64 and the liquid crystal display element 65 are the same as those already described. In this embodiment, the light sources R, G, and B of the three primary colors R, G, and B are sequentially turned on, and the display content of the image display unit is switched in synchronization with the light sources, thereby performing time-division color display. I have. Since each of the RGB images is displayed by the same optical system, the RGB light beams are completely overlapped and displayed, and color separation does not occur.

(Invention of claim 8) Although the RGB colors cannot be completely overlapped as in the invention of claim 7, the three-dimensional image display device using the horizontal parallax of the invention of claim 4 cannot be used. By using an image display unit in which RGB pixels are arranged in a vertical direction, color display can be more easily performed.

FIG. 11 is an explanatory view of a main part of a three-dimensional image display device for performing colorization according to an embodiment of the present invention. In FIG. 11, reference numeral 71 denotes a light source, 72 denotes a lens, and 73 denotes a one-dimensional image. A liquid crystal spatial modulation device, 74 is a liquid crystal display device, and 75 is an observer. The operation of this embodiment is the same as that shown in FIG. There is no optical difference with respect to the color difference in the horizontal direction in which the parallax image is displayed, so that color three-dimensional image display can be performed without causing color separation.
