BACKGROUND OF THE INVENTION 1. Field of the Invention The invention disclosed in this specification relates to a display device and a display method for displaying various kinds of information. In particular, the present invention relates to a display device and a display method that allow different images to be recognized by a plurality of observers.

For example, a method is known in which one screen is divided and a plurality of television programs are displayed at the same time, and a method in which a plurality of images are overlapped and displayed on one screen.

In the former method, since individual images are displayed independently, it is relatively easy to watch a large number of programs and images at the same time. However, the latter method has a problem that it becomes very difficult to see because a plurality of images overlap each other.

In both methods, a plurality of images are displayed at the same time, so that the viewer must select the object to be viewed.

This poses a problem when a plurality of people simultaneously see a plurality of different screens. For example, in the case of displaying an image that is visible to the observer A but not to the observer B, the above method cannot be used.

The scanning control is simultaneously performed, and each of the N peripheral circuits simultaneously performs vertical scanning control of the M active matrix regions.

In FIG. 2, M = 2 and N = in the above configuration.
The case of 3 is shown. In FIG. 2, (M = 2) × (N
= 3) active matrix regions 103 arranged in number,
104, 105, 106, 107 and 108 are shown.

Further, 2 + 3 peripheral circuits 101, 102, 109, 110, 111 are arranged as peripheral circuit regions for driving these active matrix circuits. Among these peripheral circuits, 101 and 102 are horizontal scanning control circuits. Reference numerals 109, 110, and 111 are vertical scanning control circuits.

In this case, it is necessary to use a color filter of RGB in each active matrix area to obtain a color image, or

As shown in FIG. 2, generally, M × N active matrix areas are arranged in a matrix.

Further, pixels are arranged in a matrix in the active matrix region, at least one thin film transistor is arranged in the pixel, and a signal applied to the source of the thin film transistor is supplied to each of M peripheral circuits. The signal applied to the gate of the thin film transistor is controlled by the vertical scanning control performed by each of the N peripheral circuits.

As the pixel in the above structure, for example, the region shown by the address (0,0), (1,0), ... (M, 0) shown in FIG. 2 can be mentioned. In the configuration shown in FIG.
One thin film transistor is arranged in each pixel.

The number of thin film transistors arranged in each pixel is not limited to one. As the arrangement method, a plurality of pieces may be connected in series or may be arranged in combination with a MOS capacitor. Further, not only the combinations of the same channel type but also the combinations of different channel types may be combined.

In the structure shown in FIG. 2, it is necessary for light to pass through the liquid crystal panel, so it is necessary to use a material having a light-transmitting property as the substrate. Specifically, it is necessary to use a glass substrate or a quartz substrate.

The thin film transistors arranged in the active matrix region and the thin film transistors forming the peripheral circuit are integrated on the same substrate. Such a structure is very useful for reducing the size and weight of the device and reducing the production cost.

An operation example of the configuration shown in FIG. 2 will be briefly described. In the configuration shown in FIG. 2, 109 to 1 depending on the operation clock of the vertical scanning control circuit indicated by CLKV.
The operation of the vertical scanning control circuit shown by 10 is basically controlled. The operation of the horizontal scanning control circuit indicated by 101 and 102 is basically controlled by the operation clock of the horizontal scanning control circuit indicated by CLKH.

In the following, a method of displaying an image in the active matrix area 103 will be described for the sake of simplicity. The operation of the other active matrix regions is also the same as that of the active matrix region 103.

First, the rising pulse of CLKV (operation clock of the vertical scanning control circuit) is the vertical scanning control circuit 10.
By inputting it to the flip-flop circuit 202 of No. 9, VSTA (vertical scanning timing enable signal) is punched out. At this time, the output of the flip-flop circuit 202 becomes H (high in logic level) level. Also, the output level of the other flip-flop circuit of the vertical scanning control circuit 109 remains L (Low at the logic level).

As a result, the gate signal line 211 indicated by the Y ₀ row becomes H level. And (0,0), (1,0), ...
・ All thin film transistors at address (m, 0) are turned on.

In this state, the horizontal scanning control circuit 10
In the flip-flop circuit 201 of No. 1, HSTA (horizontal scanning timing enable signal) is punched out by CLKH (horizontal scanning control circuit operation clock), and X ₀
The signal level at the point becomes H. At this time, points after X ₁ are L (Low at the logic level).

As a result, the image sampling signal line 208
The H signal is input to the sampling and holding circuit 204 via the, and the R image data signal is captured by the sampling and holding circuit 204.

Then, the image data flows through the image signal line 209. That is, the image data signal is applied to the source of the thin film transistor at the address indicated by (0,0), (0,1), (0,2) ... (0, n).

In this state, (0,0), (1,0), ...
・ All the thin film transistors at the address (m, 0) are in the ON state, and the image data signal is sent to the source of the thin film transistor at the address (0,0), (0,1), (0,2) ・ ・ ・ (0, n). Is being applied. Therefore, the image data is written in the pixel at the address (0,0).

Thereafter, the output of the flip-flop circuit 201 becomes L level at the next rising edge of the pulse of CLKH. That is, the point of X ₀ becomes the L level. On the other hand, in the flip-flop circuit 206, the C
By inputting the rising edge of the LKH pulse,
The output changes to H level. That is, the point of X ₁ becomes H level.

As a result, information is written at the address (1,0). In this way, the output of the flip-flop circuit X _m is sequentially set to H in accordance with the operation clock of CLKH.
Shift to levels. Then, the image information is sequentially written at the address (m, 0).

After the writing of information in the Y ₀ row is completed, C
At the rising edge of the LKV signal, the output level of the flip-flop circuit 202 becomes L and the output level of the flip-flop circuit 203 becomes H. As a result, the signal level of the Y ₁ row becomes H.

In line Y ₁ , (0,1), (1,1), (2,
1) ... Image data information is written in sequence to addresses (m, 1). In this way, one frame ends when the writing of information up to the address (n, m) is completed.

The above operation is performed at the same timing in the active matrix areas other than 103.

By using the integrated liquid crystal panel shown in FIG. 2, two color images of RGB can be obtained at the same time. Of course, the color images can have different contents.

Here, a structure in which six active matrix regions are integrated has been shown. However, it is possible to further increase the number of integrated active matrix regions. For example, RGB, R'G'B ', R ^,, G ^,, B
^,, and 9 active matrix regions can be integrated.

In this case, in the configuration shown in FIG. 2, it is only necessary to add one more horizontal scanning control circuit. In this case, three sets of color images can be obtained.

As described above, the integrated active matrix type liquid crystal panel whose basic structure is shown in FIG.
Even if the number of active matrix regions to be integrated is increased, it is not necessary to increase the number of peripheral drive circuits.

Specifically, if the number of active matrix regions to be integrated is M × N, the number of required peripheral drive circuits is M + N. This becomes very useful when the integration is further increased.

Further, each image projected from the optical system 508 is given a specific polarization state from the polarizing plates denoted by 512 and 513. Here, two linear polarization states different from each other by 90 ° are given.

As shown in FIG. 6, the image A _i B _i is composed of an image A _i for the right eye and an image B _i for the left eye. Here, i is a natural number including 0. The image A _i B _i becomes linearly polarized light having a predetermined direction by the polarizing plate 512 in FIG. 3 and is projected on the screen 510. Further, the image A _i and the image B _i are alternately displayed for each frame.

Similarly, the image C _i D _i is the image C for the right eye.
_i and the image D _i for the left eye. Here, i is a natural number including 0. The image C _i D _i is the polarizing plate 513 of FIG.
Results in a linearly polarized state having a direction that is 90 ° different from the image A _i B _i . Then, it is projected on the screen 510. The image C _i and the image D _i are alternately displayed for each frame.

The image A _i B _i and the image C _i D _i are superimposed and projected on the screen 510. That is, the image data of polarization state 1 and polarization state 2 shown on the display screen of FIG. 5 are displayed simultaneously.

This display is individually observed with the glasses 402 and 403. The glasses 402 include a polarizing plate 512.
It has polarizing plates 404 and 405 whose polarization directions are determined so as to transmit the polarization state given by. That is,
The polarizing plates 404 and 405 are composed of polarizing plates having the same polarization direction.

Thus, in the glasses 402, the polarizing plate 4
04 and 405 are A _0, B _0, A indicated by the polarization state 1 in FIG.
Images of _1, B _1, A _2, B ₂ ... Are transmitted.

The polarizing plates 404 and 405 are attached to the glasses 402.
Optical shutters (liquid crystal shutters in the present embodiment) 406 and 407 are provided behind. When using linearly polarized light, it is necessary to pay attention to the polarization direction of the polarizing plate arranged in the liquid crystal shutter. To avoid this problem, the liquid crystal shutter may be configured by using a dispersion type liquid crystal panel that does not use a polarizing plate.

The liquid crystal shutter 407 displays images A _0, A _1, A ₂
... is opened and closed in synchronization with the display so as to pass through.

Further, the liquid crystal shutter 406 displays images B _0, B _1,
It opens and closes in synchronization with the display so that B ₂ ... Is transmitted.

As a result, A _0,
The images indicated by A _1, A _2, ... Appear selectively, and the glasses 4
In the left-eye portion of 02, the images indicated by B _0, B _1, B ₂ ... Are selectively visible.

In this way, the glasses 402 use the three-dimensional image A _i B
You can see _i selectively.

On the other hand, in the glasses 403, a polarizing plate 408
And 409 have their polarization directions set so that they transmit the image in the polarization state provided by the polarizing plate 513. Therefore, C _0, D _0, C is transmitted through the polarizing plates 408 and 409.
_The image is represented by _1, D ₂ ...

Then, by operating the liquid crystal shutters 410 and 410 at the timings shown in FIG. 6,
The images of C _0, C ₁ ... Are selectively viewed in the right eye portion of the glasses 403, and D _0, D ₁
・ ・ You can selectively see images.

Thus, the glasses 403 use the three-dimensional image C _i D
You can see _i selectively.

In this way, the glasses 402 and 403 are
Different three-dimensional images can be viewed at the same time by the person who wears.

In the present embodiment, the polarization state given is linearly polarized light. However, when linearly polarized light is used, there is a problem that the plane of polarization shifts when the glasses are tilted, and the filter effect thereof deteriorates. To solve this problem, right-handed circularly polarized light and left-handed circularly polarized light may be used as the polarization states.

That is, right-handed circularly polarized light is given to the images A _i B _i, and left-handed circularly polarized light is given to the images C _i D _i.
The right-handed circularly polarized light may be selectively transmitted, and the glasses 403 may be configured to selectively transmit the left-handed circularly polarized light.

Further, in order to make the image easier to see, it is effective to set the time for which the liquid crystal shutter is opened to be shorter than the display time of the time-divided image of one frame.

The structure shown in this embodiment is the same as the ordinary
It becomes a three-dimensional image display device. That is, the configuration 2 shown in FIG.
By switching the 2D image and the 3D image with the D / 3D image switching unit, it is possible to display a normal TV image or a video image.

Also in this case, two independent images can be displayed. In the case of displaying two independent images in the normal display of a two-dimensional image, the liquid crystal shutters of the eyeglasses should be kept open and the time-division display should not be performed.

The positional relationship between the liquid crystal shutter and the polarizing plate in this embodiment may be reversed. Even if the positional relationship between the liquid crystal shutter and the polarizing plate is reversed, the image finally seen by the right eye or the left eye does not change.

In this embodiment, the glasses are provided with the polarizing plate and the liquid crystal shutter plate. However, since the polarizing plates 404 and 405 have the same direction, one large polarizing filter may be arranged in front of the person wearing the glasses without equipping the glasses.

In this case, even if the linearly polarized light is used, there is a significance that the filter effect by the polarizing plate does not change even if the line of sight of the person wearing the glasses is inclined. However, there is also a drawback that the visual position of the person wearing the glasses is limited.

In the operation method shown in FIG. 5, the time division display is stopped, that is, the images for the right and left eyes such as A _{i and} B _i are stopped, and the A _i B _i image and the C _i D _i image are further stopped. Have the same function as an ordinary TV receiver or display.

[Embodiment 2] In this embodiment, a plurality of three-dimensional images are separated by using time division display, and the three-dimensional image displayed by itself is further used for the right eye image by using polarization characteristics. And an image for the left eye.

When the configuration shown in this embodiment is used, it becomes possible for two or more observers to see different three-dimensional images.

FIG. 4 shows an outline of the structure shown in this embodiment.
As shown in the figure, also in this embodiment, an image is formed using the projection type display device shown in FIG. 3 which uses the liquid crystal panel shown in FIG.

In the structure shown in FIG. 6, the image displayed on the screen 510 is a pair of glasses 6 having a liquid crystal shutter and a polarizing plate.
01, 606, and 611, different three-dimensional images can be seen. The opening and closing of the liquid crystal shutter is controlled at the same time as the timing of the image displayed on the screen 510. Although a liquid crystal shutter is used here as an optical shutter, other means may be used as long as it has a predetermined operation speed and is lightweight enough not to be a burden in use.

This embodiment operates according to the operation timing chart shown in FIG. First, on the screen 510, six types of images as shown in the display screen of FIG. 7 are displayed. Here, A ₀₁ and A ₀₂ are displayed in a state of being overlapped at the same time. Further, B ₀₁ and B ₀₂ , and further C ₀₁ and C ₀₂ are displayed at the same time in an overlapping state.

In the figure, one frame is preferably set to 1/100 second or less in order to maintain the image quality. Also,
In order to maintain the image quality equivalent to or higher than that of a normal TV image, it is preferable to set the length of one frame to 1/180 seconds or less.

A ₀₁ and A ₀₂ are a right-eye image and a left-eye image forming a three-dimensional image, respectively.
Further, B ₀₁ and B ₀₂ are an image for the right eye and an image for the left eye for forming a three-dimensional image. Similarly, C ₀₁ and C ₀₂ are an image for the right eye and an image for the left eye that form a three-dimensional image.

In FIG. 7, the display screen 1 is shown in FIG.
10 is a color image formed by 103 to 105 active matrix regions. The display screen 2 is a color image formed in the active matrix areas 106 to 108 in FIG.

A feature of the operation method shown in the present embodiment is that the RGB images formed by the active matrix regions 103 to 105 and 106 to 108 in FIG. 2 are time-divided three-dimensional images. There is an image for the right eye and an image for the left eye.

That is, the active matrix regions 103 to
In 105, after forming one frame of the right eye image A ₀₁ of the three-dimensional image A, one frame of the right eye image B ₀₁ of the three-dimensional image B is formed in the next frame. After that, one frame of the right-eye image C ₀₁ of the three-dimensional image C is formed. It works like that.

On the other hand, the active matrix region 106-
In 108, after one frame of the left eye image A ₀₂ of the three-dimensional image A is formed, one frame of the left eye image B ₀₂ of the three-dimensional image B is formed in the next frame. After that, one frame of the right-eye image C ₀₂ of the three-dimensional image C is formed. It works like that.

Therefore, a set of active matrix regions 103 to 1 controlled by the common horizontal scanning control circuit 101.
Even if only the image formed in 05 is viewed, the image for the right eye of the time-divided three-dimensional image is only visible.

Similarly, a set of active matrix regions 106 to 10 controlled by a common horizontal scanning control circuit 102.
Even if only the image formed in 8 is viewed, the time-divided three-dimensional image for the left eye is only visible.

Such an operation is performed by the horizontal scanning control circuit 101.
Images for the right eye of a plurality of three-dimensional images are formed in a time-division manner in the active matrix region commonly controlled by, and for the left eye of the plurality of three-dimensional images in the active matrix region commonly controlled by the horizontal scanning control circuit 102. It can be said that this is an operation of forming the image in time division.

Then, an image for the right eye and an image for the left eye are simultaneously displayed on the screen 510, and three kinds of such displays are time-divisionally displayed.

Further, the active matrix regions 103 to
The image formed by 105 is linearly polarized in a predetermined direction by the polarizing plate 512 of the display device shown in FIG.

In addition, the active matrix region 106-
The image formed by 108 is linearly polarized by the polarizing plate 513 of the display device shown in FIG. 3 at an angle different from the predetermined direction given by the polarizing plate 512 by 90 °.

That is, A ₀₁ , B ₀₁ , C ₀₁ , A ₁₁ , B ₁₁ , C
_The image indicated by ₁₁ ... Is linearly polarized in a predetermined direction. In addition, A ₀₂ , B ₀₂ , C ₀₂ , A ₁₂ , B ₁₂ , C ₁₂
The image indicated by ... Is linearly polarized in a direction different from the predetermined direction by 90 °.

Then, the image displayed on the screen 510 is converted into special glasses 601 equipped with a liquid crystal shutter and a polarizing plate.
At 606 and 611, three observers see. At this time, the liquid crystal shutters arranged on each pair of glasses are simultaneously opened and closed by the left and right eyes at a predetermined timing as shown in FIG.

For example, the liquid crystal shutter 60 of the eyeglasses 601.
Reference numerals 4 and 605 open and close to selectively transmit the three-dimensional image A. By the operation of the shutters 604 and 605, the overlapping images of the images A ₀₁ and A ₀₂ are incident on the polarizing plates 602 and 603. The polarization state of this image A ₀₁ is the polarizing plate 51.
2 is a linearly polarized state having a predetermined direction. Further, the polarization state of the image A ₀₂ is a linear polarization state having a direction different by 90 ° from the predetermined polarization state by the polarizing plate 513.

On the other hand, the polarizing plate 60 provided in the eyeglasses 601.
The polarization direction of the polarizing plate 3 is set so as to selectively transmit the polarization state of the image A ₀₁ which has been polarized by the polarizing plate 512.

On the other hand, the polarizing plate 60 provided in the eyeglasses 601.
The polarization direction of the polarizing plate 2 is set so as to selectively transmit the polarization state of the image A ₀₂ which has been polarized by the polarizing plate 513.

That is, the polarizing plates 602 and 603 are arranged so that their polarization directions differ by 90 °.

The images A ₀₁ and A ₀₂ have a polarization direction of 9
It has linear polarization states different by 0 °. Therefore, the image A ₀₂ is selectively transmitted through the polarizing plate 602. But image A ₀₁
Does not pass through the polarizing plate 602.

On the other hand, the image A ₀₁ selectively passes through the polarizing plate 603. However, the image A ₀₂ does not pass through the polarizing plate 603.

As a result, the person wearing the eyeglasses 601 can selectively see the image A ₀₁ in his right eye and A _{02 in} his left eye.
The images in will appear selectively.

According to the same principle, the images transmitted through the liquid crystal shutters 609 and 610 of the eyeglasses 606 are B ₀₁ and B ₀₂ , and the polarizing plate 607 is arranged so as to selectively transmit the image B ₀₂ . The polarizing plate 608 is arranged so as to selectively transmit the image B ₀₁ . Then, to the person wearing the glasses 606, the image of B ₀₁ is selectively seen in the right eye,
The image of B ₀₂ is selectively visible to the left eye.

According to the same principle, the person wearing the eyeglasses 611 can selectively see the image of C ₀₁ in his right eye and the image of C _{02 in} his left eye. That is, only the image of the C ₀₁ is visible to the invisible image of the C ₀₂ in the right eye, a state in which only an image of the C ₀₂ is visible without visible image C ₀₁ in the left eye. In this way, each person wearing the glasses 601, 606, 611 can selectively see the different three-dimensional images A to C.

In this embodiment, three images are time-divided, so that three different three-dimensional images can be viewed. However, if two images are time-divided, two different three-dimensional images can be seen as in the first embodiment. Also,
By forming three or more time division screens, more different three-dimensional images can be viewed.

As the liquid crystal shutter control means,
It is preferable to use a wireless method using electromagnetic waves or infrared rays from the viewpoint of ease of use.

Further, the positional relationship between the liquid crystal shutter and the polarizing plate in this embodiment may be reversed. Even if the positional relationship between the liquid crystal shutter and the polarizing plate is reversed, the image finally seen by the right eye or the left eye is the same.

For example, the polarizing plate 602 in the eyeglasses 601.
Let us consider a case where 603 and 603 are on the screen 510 side. In this case, the images transmitted through the polarizing plate 602 are A ₀₂ and B.
_02, C _02, A ₁₂ , B _12, C ₁₂ . In addition, the polarizing plate 60
The image transmitted through 3 is A ₀₁ , B _01, C _01, A ₁₁ , B _11, C
_Eleven . Further, the liquid crystal shutters 604 and 605 selectively transmit A ₀₁ and A ₀₂ . That is, A with the right eye
₀₁ images can be viewed selectively, and A _{02 on the} left eye
You can selectively see the images of.

Further, in the present embodiment, the configuration is such that the polarizing plate and the liquid crystal shutter are arranged on the spectacles. However, since the liquid crystal shutters arranged in one pair of glasses operate at the same timing, one large liquid crystal shutter is arranged in front of the person wearing the glasses without equipping the glasses. It may be configured to.

In this case, the spectacles are characterized in that only the polarizing plate is arranged, and the constitution for controlling the liquid crystal shutters arranged in the spectacles is unnecessary.

The structure shown in FIG. 6 can be used as it is as a TV receiver or a display for displaying a normal two-dimensional image. Also, 3 as shown by A ₀₁ and A ₀₂
If the image for the right eye and the image for the left eye for the two-dimensional image are the same, it is possible to realize a configuration in which a plurality of observers can observe a normal two-dimensional screen.

Since the switching of various display methods as described above can be performed by the control portion shown in FIG. 1, it is significant that it is not necessary to prepare a different device for use.

Further, such significance becomes more useful by using the liquid crystal panel integrated as shown in FIG. That is, as shown in FIG. 2, the peripheral circuits are made common, and the active matrix circuit and the peripheral drive circuit are integrated, thereby simplifying the configuration required for switching some display systems as described above. be able to. This is extremely significant in terms of reduction of manufacturing cost and improvement of reliability.
