<A: First Embodiment>
FIG. 1 is a block diagram showing a configuration of a display device according to the first embodiment of the present invention. As shown in the figure, the display device 100 includes a lighting device 10, a liquid crystal device 20, and a driving device 50. The illumination device 10 is installed on the back side of the liquid crystal device 20 to illuminate the display device 100.

  The liquid crystal device 20 includes a first substrate 21 and a second substrate 22 that face each other. Liquid crystal (not shown) is sealed in the gap between the first substrate 21 and the second substrate 22. A liquid crystal that responds at high speed such as an OCB (Optically Compensated Bend) mode is preferably used. On the surface of the second substrate 22 facing the liquid crystal, a plurality of pixel electrodes 24 corresponding to each pixel of the image are arranged in a matrix over the X and Y directions intersecting each other. The orientation of the liquid crystal sandwiched between the first substrate 21 and the second substrate 22 changes according to the potential difference between each pixel electrode 24 and the counter electrode (not shown) on the surface of the first substrate 21. Therefore, the ratio (transmittance) of the amount of light transmitted to the observation side in the emitted light from the illumination device 10 is controlled for each pixel electrode 24. A colored layer (color filter) is not formed in the liquid crystal device 20.

  FIG. 2 is a plan view and a side view showing the configuration of the illumination device 10. As shown in the figure, the illumination device 10 includes a light source 12, a light guide 14, a liquid crystal shutter 16, and an optical body 18. In FIG. 1, the liquid crystal shutter 16 and the optical body 18 are not shown.

  The light guide 14 is a rectangular plate material facing the second substrate 22 of the liquid crystal device 20. The light source 12 is disposed so as to face the side surface of the light guide 14 and illuminates the side surface. The light source 12 includes a plurality of light emitters 13 (13r, 13g, 13b) each emitting monochromatic light corresponding to a different color. The light emitter 13r emits monochromatic light (red light) having a wavelength corresponding to red. Similarly, the light emitter 13g emits green light, and the light emitter 13b emits blue light. The light guide 14 emits incident light from the light source 12 from the entire surface on the liquid crystal device 20 side.

  The liquid crystal shutter 16 of FIG. 2 is inserted in a gap between the liquid crystal device 20 and the light guide 14 (for example, a surface of the light guide 14 facing the liquid crystal device 20). The liquid crystal shutter 16 is configured by sealing liquid crystal between opposing substrates, and the transmittance of the liquid crystal is individually controlled by the plurality of regions AR and the plurality of regions AL. Each area AR and each area AL extends in the Y direction and is alternately arranged along the X direction. Light emitted from the light guide 14 passes through each area AR or each area AL and is emitted to the liquid crystal device 20 side.

  The optical body 18 is inserted in the gap between the liquid crystal device 20 and the liquid crystal shutter 16. As shown in FIG. 2, the optical body 18 is a light transmissive member in which a plurality of lenticular lenses 182 extending in the Y direction are arranged in the X direction. When viewed from the direction perpendicular to the light emitting surface (XY plane), one lenticular lens 182 overlaps the region AR and the region AL adjacent to each other in the X direction in the liquid crystal shutter 16. As shown in FIG. 2, each lenticular lens 182 advances the light emitted from the area AR in the direction DR and advances the light emitted from the area AL in the direction DL. The outgoing light in the direction DR passes through the liquid crystal device 20 and reaches the right eye of the observer. The outgoing light in the direction DL reaches the left eye of the observer after passing through the liquid crystal device 20.

  As shown in FIG. 1, an input image signal SIN is supplied to the driving device 50 from an external device (not shown). The input image signal SIN is a signal that designates the display color of each pixel for each of the right-eye image and the left-eye image that have parallax. The input image signal SIN designates the gradation individually for each of the three kinds of primary color components (red, green and blue) constituting the display color of the pixel. That is, the input image signal SIN includes a gradation GR_r of a red component (hereinafter referred to as “R component”), a gradation GR_g of a green component (hereinafter referred to as “G component”), and a blue component (hereinafter referred to as “B component”). For each pixel, and for the left-eye image, an R component gradation GL_r, a G component gradation GL_g, and a B component gradation GL_b are specified for each pixel.

  The driving device 50 in FIG. 1 is a circuit that drives the illumination device 10 and the liquid crystal device 20 based on an input image signal SIN. The drive device 50 includes an illumination drive circuit 52 that drives the illumination device 10 and a liquid crystal drive circuit 54 that drives the liquid crystal device 20. In addition, the aspect of mounting the driving device 50 is arbitrary. For example, a configuration in which the illumination drive circuit 52 is mounted on the illumination device 10 and the liquid crystal drive circuit 54 is mounted on the liquid crystal device 20 or a configuration in which the illumination drive circuit 52 and the liquid crystal drive circuit 54 are mounted on a single integrated circuit is adopted. Is done.

  FIG. 3 is a timing chart for explaining the operation of the display device 100. Note that the symbol R in FIG. 3 means a right-eye image, and L means a left-eye image. The symbol r means the R component, the symbol g means the G component, and the symbol b means the B component. Therefore, for example, the symbol “R-r” in FIG. 3 means a monochromatic image of the R component of the right-eye image.

  The unit period F (F1, F2, F3,...) In FIG. 3 is a period (frame) used for displaying one image stereoscopically viewed by the observer. As shown in FIG. 3, one unit period F is divided into a period FR for displaying a right-eye image and a period FL for displaying a left-eye image. Each of the period FR and the period FL is composed of three subfields SF (SF1 to SF3) corresponding to different primary color components. Each subfield SF includes a writing period PW and a display period PD. Monochromatic images of the primary color components constituting the right eye image are sequentially displayed in the subfields SF1 to SF3 of the period FR, and the monochromatic images of the primary color components constituting the left eye image are displayed in the subfields SF1 to SF3 of the period FL. The driving device 50 drives the illumination device 10 and the liquid crystal device 20 so that the images are sequentially displayed.

  The liquid crystal driving circuit 54 determines the potential of each pixel electrode 24 of the liquid crystal device 20 for the primary color component in the writing period PW of the subfield SF in which the primary color component of the left-eye image or right-eye image is to be displayed. The data potential is set according to the gradation specified by the input image signal SIN. For example, in the writing period PW of the subfield SF (for example, the subfield SF1 of the period FR in the unit period F1) in which the R component monochromatic image is to be displayed in the period FR, the liquid crystal driving circuit 54, as shown in FIG. Then, a data potential corresponding to the gradation GR_r of the R component of the right-eye image is supplied to each pixel electrode 24 (R-r writing). Further, in the writing period PW of the subfield SF (for example, the subfield SF3 of the period FL in the unit period F1) in which the B component monochrome image is to be displayed in the period FR, the liquid crystal driving circuit 54 performs the B component of the left eye image. Is supplied to each pixel electrode 24 (L-b writing). The transmittance of the liquid crystal in the immediately subsequent display period PD is determined according to the data potential set for the pixel electrode 24 in the writing period PW.

  As shown in FIG. 1, the illumination driving circuit 52 includes a light source driving unit 522 that controls the light source 12 and a direction switching unit 524 that controls the liquid crystal shutter 16. The light source driving unit 522 selectively turns on the light emitters 13 corresponding to the primary color components of the single color image to be displayed in each subfield SF in the display period PD of the subfield SF. For example, as shown in FIG. 3, in the display period PD of the subfield SF in which the R component single color image of the right eye image or the left eye image is to be displayed, the light source driving unit 522 causes the light emitter 13r to emit light and the light emitter. 13g and the light emitter 13b are turned off. Similarly, the light source driving unit 522 emits only the light emitter 13g in the display period PD of the subfield SF in which the G component is to be displayed, and the light emitter 13b in the display period PD of the subfield SF in which the B component is to be displayed. Only emit light.

  The direction switching unit 524 in FIG. 1 sets the emitted light from the illumination device 10 in either the direction DR or the direction DL by individually controlling the transmittance of the liquid crystal shutter 16 in each area AR and each area AL. Means. More specifically, as shown in FIG. 3, the direction switching unit 524 increases the transmittance of each area AR in the display period PD of each subfield SF (period FR) in which the monochromatic image for the right eye is to be displayed. (ON) and the transmittance of each region AL is decreased (OFF), and the transmittance of each region AL is increased in the display period PD of each subfield SF (period FL) where the monochromatic image for the left eye is to be displayed. And the transmittance of each area AR is reduced.

  Since the driving device 50 operates as described above, in the display period PD of the subfield SF in which the single-color image of each primary color component of the right-eye image is to be displayed, the single-color light of the primary color component is directed from each area AR in the direction DR. In the display period PD of the subfield SF where the monochromatic image of each primary color component of the left eye image is to be emitted and transmitted through the liquid crystal device 20, the monochromatic light of the primary color component is emitted from each area AL in the direction DL. And passes through the liquid crystal device 20. The observer perceives the color right-eye image by sequentially viewing each single-color image of the right-eye image with the right eye in the subfields SF1 to SF3 in the period FR, and in the subfields SF1 to SF3 in the period FL. In this way, each monochrome image of the left-eye image is sequentially viewed with the left eye to perceive a color left-eye image. Therefore, the observer perceives a color image with a stereoscopic effect for each unit period F.

  As shown in FIG. 3, the driving device 50 is configured so that the order of the primary color components of the monochromatic image displayed in each of the period FR and the period FL is different in the unit periods F that follow each other. And the liquid crystal device 20 is driven. For example, as shown in FIG. 2, in the period FR and the period FL of the unit period F1, the single-color images of the right-eye image and the left-eye image are displayed in the order of R component → G component → B component, In the unit period F2, monochromatic images are displayed in the order of G component → B component → R component, and in the unit period F3, monochromatic images are displayed in the order of B component → R component → G component. For each unit period F subsequent to the unit period F3, the same order as the unit periods F1 to F3 is repeated.

  As described above, in this embodiment, since the order of the display colors of each single-color image (particularly, the first display color of the period FR or the period FL) changes for each unit period F, the order of the display colors of the single-color images. Compared with a configuration in which the unit is fixed over all unit periods F, color breaks perceived by the observer can be reduced.

  Further, in the present embodiment, each of the right-eye image and the left-eye image is displayed in a time-sharing manner using all the pixels of the liquid crystal device 20, and therefore, a configuration in which a parallax barrier is installed on the front side of the liquid crystal device 20 (right eye It is possible to increase the resolution of the image perceived by the observer as compared to the configuration in which the image for the left eye and the image for the left eye are displayed on the liquid crystal device 20 simultaneously. Furthermore, since a color image is displayed by the frame sequential method, the liquid crystal device 20 does not need to display a plurality of primary color components simultaneously. Therefore, the effect that an image with a high resolution is displayed becomes particularly remarkable.

<B: Second Embodiment>
Next, a second embodiment of the present invention will be described. In addition, about each element which an effect | action and a function are equivalent to 1st Embodiment in each form illustrated below, the same code | symbol as above is attached | subjected and each detailed description is abbreviate | omitted suitably.

  In the first embodiment, the single-color images of the right-eye image are sequentially displayed in the period FR that is continuous within the unit period F, and the single-color images of the left-eye image are displayed in the period FL that is continuous within the unit period F. A configuration for sequentially displaying was illustrated. In this embodiment, each single-color image of the right-eye image and each single-color image of the left-eye image are alternately displayed in each subfield SF within the unit period F.

  FIG. 4 is a timing chart for explaining the operation of the display device 100. As shown in the figure, each unit period F is divided into six subfields SF1 to SF6. In each display period PD of the odd-numbered subfield SF (SF1, SF3, SF5), the single-color images of the primary color components of the right-eye image are sequentially displayed, and the even-numbered subfield SF (SF2, SF4, SF6) is displayed. In each display period PD, monochromatic images of the primary color components of the left eye image are sequentially displayed. In each unit period F, single-color images of three primary color components are displayed for each of the right-eye image and the left-eye image.

  The driving device 50 drives the illuminating device 10 and the liquid crystal device 20 so that the order of the primary color components of the monochromatic images displayed in the subfields SF1 to SF6 is different in the unit period F that follows. That is, as shown in FIG. 4, the single-color images of the right-eye image and the left-eye image are displayed in the order of R component → G component → B component → R component → G component → B component in the unit period F1. In the period F2, G component → B component → R component → G component → B component → R component are displayed in the order, and in the unit period F3, B component → R component → G component → B component → R component → G component in this order. Is displayed. Therefore, the same effects as those of the first embodiment can be obtained in this embodiment.

  By the way, in the configuration in which the monochromatic images of the right-eye image and the left-eye image are displayed in a time-division manner as in each of the above embodiments, the light emitted from the liquid crystal device 20 is intermittently applied to each of the observer's right eye and left eye. To reach. That is, the image does not reach the left eye of the observer when displaying each monochrome image of the right eye image, and the image does not reach the right eye of the observer when displaying each monochrome image of the left eye image. In the configuration in which the monochromatic image of the right-eye image and the monochromatic image of the left-eye image are alternately displayed for each subfield SF as in the present embodiment, a plurality of monochromatic images constituting the right-eye image are continuously displayed in the period FR. In addition, as compared with the first embodiment in which a plurality of single-color images constituting the left-eye image are continuous in the period FL, the period in which the emitted light from the liquid crystal device 20 reaches one eye of the observer is shortened. Therefore, according to the present embodiment, there is an advantage that it is difficult for an observer to perceive periodic brightness fluctuation (flicker) of the liquid crystal device 20.

<C: Third Embodiment>
Next, a third embodiment of the present invention will be described. In the first embodiment and the second embodiment, the configuration in which single-color images of three kinds of primary color components are displayed for each of the right-eye image and the left-eye image is exemplified. In this embodiment, single-color images of a plurality of color components extracted from the display color specified by the input image signal SIN are displayed for the right-eye image and the left-eye image.

  FIG. 5 is a block diagram illustrating a configuration of the display device 100. As shown in the figure, the display device 100 of the present embodiment includes an image processing device 40 in addition to the elements of the first embodiment. The image processing device 40 generates and outputs a separated image signal S from the input image signal SIN. The separated image signal S is a signal that designates the gradation of each component when the display color designated by the input image signal SIN is separated into a plurality of color components for each pixel of the right-eye image and the left-eye image. The separated image signal S of this embodiment includes a cyan (C) component, a yellow (Y) component, a magenta (M) component, and a white component in addition to the gradations of the three primary color components similar to those in the first embodiment. The (W) component is designated for the right-eye image and the left-eye image.

  Part (a) of FIG. 6 shows a specific example of the gradation (GR_r, GR_g, GR_b) of each primary color component that the input image signal SIN designates for one pixel of the right-eye image. The image processing apparatus 40 sets the minimum value Gmin of the gradations (GR_r, GR_g, GR_b) of the three kinds of primary color components specified for one pixel by the input image signal SIN as the gradation GR_w of the white component. Further, the image processing apparatus 40 separates the G component and the B component remaining after the extraction of the white component into the mixed color (C component) and the B component as shown in the part (b) of FIG. The gradation (GR_c, GR_b) is designated by the separated image signal S. If the R component and the G component remain after extraction of the white component, the gradation of the Y component is specified by the separated image signal S. If the B component and the R component remain, the M component level is determined. The tone is specified by the separated image signal S. Moreover, although the image for right eyes was illustrated in FIG. 6, it processes similarly about the image for left eyes.

  FIG. 7 is a timing chart illustrating the order of the display colors of the single-color image for each of the right-eye image and the left-eye image. Each of the period FR and the period FL in the unit period F is divided into seven subfields SF (SF1 to SF7). In FIG. 7, the writing period PW is not shown.

  As illustrated in FIG. 7, the driving device 50 controls the illumination device 10 and the liquid crystal device 20 based on the separated image signal S, so that a plurality of color components (a white component and three kinds of primary colors) constituting the right-eye image. Component and three types of mixed color components) are sequentially displayed in the subfields SF1 to SF7 of the period FR. Similarly, in the subfields SF1 to SF7 in the period FL, the single color images of a plurality of color components constituting the left eye image are sequentially displayed.

  The driving device 50 changes the order of display colors of the single-color images for each unit period F. For example, in the unit period F1, the monochrome images of the right eye image and the left eye image are displayed in the order of W component → R component → Y component → G component → C component → B component → M component. In the unit period F2, monochromatic images are displayed in the order of R component → Y component → G component → C component → B component → M component → W component. Therefore, the same effects as those of the first embodiment can be obtained in this embodiment.

  Furthermore, since the monochromatic image of the white component and the mixed color component is sequentially displayed in addition to the primary color component, it is possible to suppress color breakup compared to the configuration of the first embodiment in which only the monochromatic image of the primary color component is displayed. Is possible. Note that the configuration of this embodiment that displays a monochromatic image of a mixed color component or a white component extracted from the input image signal SIN may be adopted in the second embodiment. For example, a single color image of a plurality of color components (white component, three primary color components, and three types of mixed color components) of the right eye image and a single color image of the plurality of color components of the left eye image are alternately displayed for each subfield SF. A display configuration is adopted.
