Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic image display device capable of observing a color stereoscopic image without using special glasses.

[0002]

2. Description of the Related Art Conventionally, a parallax barrier method as shown in FIG. 6 has been proposed as a method for displaying a stereoscopic image without using glasses.

In FIG. 6, 1 is a display panel such as a liquid crystal panel for displaying a color image, and 2 is a barrier substrate which allows a part of light from each picture element of the display panel 1 to pass therethrough. The arrangement pattern of the picture elements of the display panel 1 is, in order along the left-right direction, a red picture element R1 for the left eye and a green picture element G for the right eye.
2. A blue pixel B1 for the left eye, a red pixel R2 for the right eye, a green pixel G1 for the left eye, and a blue pixel B2 for the right eye are repeatedly arranged in this order.

The barrier substrate 2 is a slit-shaped substrate in which a plurality of vertically elongated openings 2a for transmitting light from each picture element of the display panel 1 are formed via barrier portions 2b for shielding light.

In the stereoscopic image display device having such a structure,
In the front of the display surface, only the light emitted from the left-eye picture elements R1, G1, and B1 enters through the opening 2a of the barrier substrate 2, and the right-eye picture elements R2, G2, The light emitted from B2 is blocked by the barrier portion 2b and does not enter, and vice versa, only the light emitted from the right-eye picture elements R2, G2, and B2 is the opening 2a of the barrier substrate 2. Light that passes through and is emitted from the left-eye picture elements R1, G1, and B1 is blocked by the barrier section 2b and does not enter the area 3
2 and are formed.

Then, the distance between the area 31 and the area 32 is set to be the human eye distance (for example, 65 mm), the observer's left eye is positioned in the area 31, and the right eye is set to the area. By arranging it at 32, the observer can recognize only the left-eye picture elements R1, G1, B1 with the left eye and the right-eye picture elements R2, G2, B2 with the right eye. , You can watch 3D images.

In the stereoscopic image display device as described above, the pitch between the left-eye picture element and the right-eye picture element of the display panel is set to P.
(Equal to the pixel pitch P), E is the human eye distance, t1 is the distance from the display surface of the display panel 1 to the barrier substrate 2,
When the suitable viewing distance from the barrier substrate 2 to the regions 31 and 32 is L1, P: t1 = E: L1 and the following equation 1 is established.

[0008]

[Equation 1]

That is, the optimum viewing distance L1 from the barrier substrate 2 to the regions 31 and 32 is inversely proportional to the pitch P between the left-eye picture element and the right-eye picture element. However, for example, the pixel pitch is 0.0175 mm and the glass substrate thickness is 0.85.
When a liquid crystal panel of mm (this value is an air-equivalent distance in consideration of the refractive index of the glass substrate) is used, and a barrier substrate is adhered to the glass substrate of the liquid crystal panel to form the stereoscopic image display device as described above. , P = 0.175 mm, t1 =
It becomes 0.85 mm, and the suitable viewing distance L1 becomes as large as 3 m or more. Therefore, there is a problem that the viewer cannot observe the stereoscopic image unless he is far away from the display screen, and cannot see the stereoscopic image with a sense of reality.

FIG. 7 shows a conventional stereoscopic image display device in which a barrier substrate 4 is arranged on the light incident side of the display panel 1. The barrier substrate 4 is a slit-shaped substrate in which a plurality of vertically elongated openings 4a for transmitting light from the flat light source 5 are formed via barrier portions 4b for shielding light.

In the stereoscopic image display device having such a structure,
The light emitted from the flat light source 5 becomes slit-shaped light that passes through the opening 4 a of the barrier substrate 4. This allows
In the front of the display panel 1, only the light passing through the left-eye picture elements R1, G1, and B1 of the slit-shaped light enters, and passes through the right-eye picture elements R2, G2, and B2. The area 61 where light does not enter, and vice versa, the picture elements R2 and G2 for the right eye,
Only the light that has passed through B2 enters, and the left-eye picture elements R1 and G
A region 62 is formed in which the light that has passed through 1 and B1 does not enter.

Then, the distance between the area 61 and the area 62 is set so as to be the human eye distance (for example, 65 mm), the observer's left eye is located in the area 61, and the right eye is located in the area. By positioning it at 62, the observer can recognize only the left-eye picture elements R1, G1, and B1 with the left eye and the right-eye picture elements R2, G2, and B2 with the right eye. , You can watch 3D images.

In the stereoscopic image display device as described above, the pitch between the left-eye picture element and the right-eye picture element is P (picture element pitch P
When the human eye distance is E, the distance from the barrier substrate 4 to the display panel 1 is t2, and the suitable viewing distance from the display panel 1 to the regions 61 and 62 is L2, P:
Since t2 = E: L2 + t2, the following equation 2 holds.

[0014]

[Equation 2]

That is, the suitable viewing distance L from the display panel 1 to the regions 61 and 62 is inversely proportional to the pitch P between the left-eye picture element and the right-eye picture element. However, for example, as in the case of the stereoscopic image display device shown in FIG.
A liquid crystal panel having a thickness of 75 mm and a glass substrate thickness of 0.85 mm (this value is an air-equivalent distance considering the refractive index of the glass substrate) is used. When the video display device is configured,
P = 0.175 mm, t1 = 0.85 mm, and the suitable viewing distance L2 is increased to 3 m or more. Therefore, there is a problem that the viewer cannot observe the stereoscopic image unless he is far away from the display screen, and cannot see the stereoscopic image with a sense of reality.

[0016]
