DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color display using a reflective display device operating in a birefringence mode.

[0002]

2. Description of the Related Art FIG. 1 schematically shows an example of a conventional color display device using a reflective display device. In this color display device, readout light emitted from a light source 7 (for example, a metal halide lamp) is separated into a P polarization component and an S polarization component by a polarization beam splitter 6. That is, the P-polarized component passes through the polarizing beam splitter 6 as it is, and the S-polarized component is reflected and bent toward the dichroic mirror 4. Dichroic mirror 4
Reflects only the wavelength component corresponding to the green light in the S-polarized component and supplies it to the reflective display device 1 for green.
Wavelength components corresponding to red light and blue light are transmitted. The red light and the blue light transmitted through the dichroic mirror 4 are further separated by the dichroic mirror 5 and the red light is supplied to the red reflective display device 2 and the blue light is supplied to the blue reflective display device 3.

Here, the reflective display devices 1, 2, and 3 for green, red, and blue respectively modulate and reflect the supplied color light as a difference in polarization state. The green light modulated and reflected by the reflective display device 1 for green is reflected again by the dichroic mirror 4 and enters the polarization beam splitter 6. The red light modulated and reflected by the reflective display device 2 for red is reflected again by the dichroic mirror 5, passes through the dichroic mirror 4, and enters the polarization beam splitter 6. The blue light modulated and reflected by the reflective display device 3 for blue passes through the dichroic mirror 5 and the dichroic mirror 4 and enters the polarization beam splitter 6. Then, the polarization beam splitter 6
Transmits only the P-polarized light component of each color light modulated as a difference in polarization state. This transmitted light is, for example, the projection lens 8
Thus, a color image is projected on a screen (not shown) and displayed.

[0004]

However, in the above-mentioned conventional color display device, the red light modulated by the reflective display device 2 for red light is reflected by the dichroic mirror 4.
Is transmitted to the polarization beam splitter 6, and the blue light modulated by the reflective display device 3 for blue is transmitted through the dichroic mirror 5 and the dichroic mirror 4 and guided to the polarization beam splitter 6. In addition, not only the efficiency of using light when passing through these dichroic mirrors is reduced, but also a phase shift occurs and a contrast ratio is reduced. Further, of the light emitted from the light source 7, only the S-polarized light component is reflected and separated by the polarizing beam splitter 6 and supplied to each reflection type display device, and the P-polarized light component cannot be used. There is a problem that the light use efficiency is extremely low because of the following. Furthermore,
In the display device described above, the back focus of the projection lens 8 needs to be set to be long because of the configuration in which three reflective display devices are provided corresponding to the three primary colors. Not only is there a big constraint,
Registration of the reflective display devices becomes difficult.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram schematically showing a schematic configuration of the first embodiment of the present invention. The readout light emitted from the light source 7 is guided to the dichroic mirror 11 as a substantially parallel light beam from which heat rays have been removed by the lens 14, the cold mirror 15, and the lens 16. Here, the dichroic mirror 11 reflects blue light and transmits green light and red light.
The green light and the red light transmitted through the dichroic mirror 11 are further separated by the dichroic mirror 12. That is, the dichroic mirror 12 reflects red light and transmits green light. The green light transmitted through the dichroic mirror 12 is further reflected by the dichroic mirror 13.
Here, the dichroic mirror 13 may be a total reflection mirror having no wavelength dependency.

Thus, the light emitted from the light source 7 is
The light is reflected by the dichroic mirrors 11, 12, and 13, respectively, and is separated into three primary colors of light. However, the reflecting surfaces of the dichroic mirrors are configured to be non-parallel to each other.
Each primary color light is incident on the polarization separation surface 6a of the polarization beam splitter 6 at a different angle (θ1, θ2, θ3). Therefore, the polarization beam splitter 6 reflects the S-polarized light component of each primary color light at angles of θ1, θ2, and θ3, and makes the light enter the reflection type display device 9.
Here, the polarization beam splitter 6 has the characteristics shown in FIG. 7 for the blue light incident at θ1, the red light incident at θ2, and the green light incident at θ3 as the characteristics of the polarization separation surface 6a. Has been granted. In FIG.

The reflective display device 9 selectively condenses each primary color light to a corresponding color pixel by utilizing a difference in incident angle of each primary color light. The configuration of the reflective display device 9 will be described later. Each primary color light condensed on each color pixel is modulated as a difference in polarization state, is reflected by a dielectric mirror 9b described later, and is incident on the polarization beam splitter 6 again. Then, the polarization beam splitter 6 transmits only the P-polarized component of each modulated primary color light and guides it to the projection lens 8. The projection lens 8 forms and displays a color image on a screen (not shown).

Here, two types of configurations of the reflective display device 9 will be described with reference to FIG. 4 or FIG. FIGS. 4A and 4B are diagrams schematically showing a first configuration example of the reflective display device 9. FIG. 4A is a partial cross-sectional view of the reflective display device 9, and FIG. FIG. As shown in FIG. 4A, in this configuration example, a dielectric mirror layer 9b and a liquid crystal layer 9c are provided between a pixel electrode 9a and a transparent electrode (ITO) 9d. 9a drives the liquid crystal layer. The pixel electrode 9a is composed of independent color pixel electrodes of a green pixel electrode 9aG, a red pixel electrode 9aR, and a blue pixel electrode 9aB, and a unit pixel is formed by three color pixel electrodes. Here, FIG.
As shown in (B), the unit pixel electrodes are repeatedly arranged in the row direction (horizontal direction) and repeatedly arranged in the same direction in the column direction (vertical direction). Further, a microlens (lenticular lens) 9e is formed corresponding to the arrangement of the unit pixel electrodes in each column. That is, in this configuration example of the reflection type display device, each primary color light coming at different angles θ1, θ2, θ3 is selectively condensed to the corresponding color pixel electrode by the action of the lenticular lens 9e. .

Next, a second configuration example of the reflective display device 9 will be described with reference to FIG. FIGS. 6A and 6B are diagrams schematically showing a second configuration example of the reflective display device 9. FIG. 6A is a partial sectional view of the reflective display device 9, and FIG. FIG. FIG.
As shown in (A), in this configuration example, a dielectric mirror layer 9b and a liquid crystal layer 9c are provided between the pixel electrode 9a and the transparent electrode (ITO) 9d, and the transparent electrode 9d and each pixel electrode 9a The liquid crystal layer is driven by the signal voltage applied during the period. The pixel electrode 9a is a green pixel electrode 9a.
G, a red pixel electrode 9aR, and a blue pixel electrode 9aB are configured by independent color pixel electrodes, respectively, and a unit pixel is formed by three color pixel electrodes. These points are the same as in the case of the first configuration example described above.

In this configuration example, the pixels in the even rows and the pixels in the odd rows are arranged out of phase by 0.5 pixel in the repetition cycle of the unit pixel. That is, as shown in FIG. 6B, the blue pixel electrodes 9aB and the green pixel electrodes 9aG in the odd-numbered rows are used.
Red pixel electrodes 9aR in even rows are arranged at intermediate positions of
An even-numbered blue pixel electrode 9aB is arranged at an intermediate position between the odd-numbered green pixel electrode 9aG and the red pixel electrode 9aR, and an even-numbered green pixel electrode 9aG is provided at an intermediate position between the odd-numbered red pixel electrode 9aR and the blue pixel electrode 9aB. Are arranged. The microlenses 9e for selectively condensing each primary color light on each color pixel electrode are formed in a honeycomb shape centering on the red pixel electrodes 9aR in each row. As described above, according to the configuration of the first embodiment, each primary color light modulated by the reflective display device 9 is guided to the projection lens 8 without passing through the dichroic mirrors 11, 12, and 13. Since the projection is performed, a high-contrast image can be displayed without a decrease in light utilization rate or a phase shift caused by the dichroic mirrors 11, 12, and 13. In the first embodiment described herein, the S-polarized light component reflected by the polarization splitting surface 6a of the polarization beam splitter 6 is used for reading. However, the reflection type display faces the emission surface of the P-polarized light component. The device 9 may be arranged to perform reading with the P-polarized component.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a diagram schematically showing a schematic configuration of the second embodiment of the present invention. Note that, in comparison with the above-described first embodiment, the present embodiment is an example in which a reflective display device 10 is provided in addition to the reflective display device 9 to configure a two-panel color display device. The description of the same configuration as that of the first embodiment is omitted. In the present embodiment, the P-polarized light component transmitted through the polarization beam splitter 6 is made incident on the reflective display device 10 as readout light so as to increase the use efficiency of light emitted from the light source 7. That is, the P-polarized light components of the primary color lights transmitted through the polarizing beam splitter 6 have different incident angles θ1, θ2,
When the light enters the reflective display device 10 at θ3, the reflective display device 10 selectively uses each primary color light to a corresponding color pixel using the difference in the incident angle of each primary color light, similarly to the reflective display device 9. Focus on Each primary color light condensed on each color pixel is modulated and reflected as a difference in polarization state, and is incident on the polarization beam splitter 6 again. The polarizing beam splitter 6 reflects the modulated S-polarized light component of each primary color light to guide it to the projection lens 8.

When the reflective display devices 9 and 10 having the configuration shown in FIG. 4 described in the first embodiment are used, as shown in FIG. The pixels are relatively shifted in the horizontal direction by 5 pixels. In FIG. 5, a solid line indicates the lenticular lens and each pixel electrode of the reflective display device 9, and a broken line indicates the lenticular lens and each pixel electrode of the reflective display device 10, respectively. In this way, by arranging the reflective display device 9 and the reflective display device 10 equivalently shifted in the horizontal direction, the resolution in the horizontal direction can be adjusted to the single-panel color display device of the first embodiment described above. It can be effectively doubled in comparison. When the reflective display devices 9 and 10 having the configuration of FIG. 6 described in the first embodiment are used, one of the reflective display devices is perpendicular to the other reflective display device. They are equivalently shifted by one line. Thus, the horizontal repetition period of each color pixel is １ ／ compared to the single-plate configuration, and the horizontal resolution can be effectively doubled. Furthermore, the reflective display device 9 having the configuration of FIG.
When 10 is used, the horizontal resolution can be effectively doubled even if the configuration is shifted by 0.5 times the pitch of the unit pixels in the horizontal direction.

As described above, according to the configuration of the second embodiment, the S-polarized light component of each primary color light separated by the polarization beam splitter 6 is modulated by the reflective display device 9 and separated by the polarization beam splitter 6. Since the P-polarized light component of each primary color light is modulated by the reflective display device 10 and guided to the projection lens 8, the light utilization by the dichroic mirrors 11, 12, and 13 is the same as in the first embodiment. In addition to obtaining a high contrast without causing a decrease in phase or causing a phase shift, a P-polarized light component that cannot be used in the color display device described in the first embodiment can be effectively used. It is possible to display an image with twice the brightness as compared with.

Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 8 is a diagram schematically showing a schematic configuration of the third embodiment of the present invention. In this embodiment, when compared with the above-described first embodiment, the polarizing beam splitter 6 in the first embodiment is omitted, and the dichroic mirrors 11, 12, and 13 have a function as a polarizing beam splitter. It is provided. That is, in the present embodiment, the light radiated from the light source 7 is converted into its light by the dichroic polarization beam splitter 21 that reflects blue light.
The polarized light component is reflected, and the P-polarized light component of the light in the other band and the blue light is transmitted. Then, only the S-polarized light component of the red light of the light transmitted through the dichroic polarizing beam splitter 21 is reflected by the dichroic polarizing beam splitter 22 that reflects the red light, and then passes through the dichroic polarizing beam splitter 21 described above. The remaining blue light and red light P-wave and green light pass through the dichroic polarizing beam splitter 22, and the S-polarized component of green light is reflected by the dichroic polarizing beam splitter 23 that reflects green light, and the dichroic polarizing beam splitter 21. 22 and proceed. The luminous fluxes of the primary color lights reflected and separated by the dichroic polarizing beam splitters 21, 22, and 23 have different incident angles θ1, θ2, respectively.
At the angle θ3 (in the example of the figure, the incident angle θ2 of the green light coincides with the normal line of the device and θ2 = 0), and the light goes toward the reflective display device 9. Here, the reflective display device 9 is the same as that described in the first embodiment with reference to FIG. 4 or FIG.

Therefore, the luminous flux of each primary color light enters the microlens at different angles θ1, θ2, θ3, and is selectively focused on the corresponding color pixels. The light beams of the primary colors modulated in this way are reflected polarization beam splitters 21 and 2.
The light is reflected toward 2 and 23, only the respective P waves are extracted, and a color image is projected on the screen by the projection lens 8. As described above, in this embodiment, the optical system can be made compact by configuring the polarizing beam splitter and the dichroic mirror for color separation with one member, and at the same time, the film can be designed for each primary color light. A color display device having a further improved ratio can be constructed.

[0021]

As described above, according to the first aspect of the invention, each primary color light modulated by the reflective display device is guided to the projection lens without passing through the dichroic mirror and projected. Therefore, a high-contrast image can be displayed without lowering the light utilization rate or phase shift due to the dichroic mirror.

According to the second aspect of the present invention, since the polarizing beam splitter and the dichroic mirror for color separation are constituted by one member, the optical system can be compactly formed, and at the same time, each primary color light can be separately provided. Since the film can be designed, a color display device with an improved contrast ratio can be realized.

Further, according to the third aspect of the present invention,
Each primary color light modulated by the reflective display device is guided and projected to the projection lens without passing through the dichroic mirror, so that it is high without causing a decrease in light utilization rate or phase shift by the dichroic mirror. Not only can a contrast be obtained, but also a P-polarized light component that cannot be used in a conventional three-plate type color display device can be effectively used, and an image with twice the brightness as compared with a conventional color display device can be displayed. Things. According to the fourth and fifth aspects of the present invention, the resolution in the horizontal direction can be effectively doubled by disposing the two reflective display devices so as to be shifted from each other.
