Problems solved by technology

[0005] However, although moiré can be reduced to some extent in the above techniques, crosstalk occurs in proportion to the moiré reduction
As a result, the visibility as 3D is significantly reduced

[0025] [Example of Configuration of Stereoscopic Image Display Device]

[0026] figure 1 is a view showing an example of the configuration of a stereoscopic image display device of an embodiment of the present disclosure.

[0027] The stereoscopic image display device 11 displays a stereoscopic image and a planar image while performing display switching between a three-dimensional stereoscopic image based on the parallax barrier method and a two-dimensional planar image as needed. The stereoscopic image display device 11 is configured to include a display unit 21 , a control unit 22 and a parallax barrier driving unit 23 .

[0028] The display unit 21 includes a backlight 31, a light modulation panel 32, and a parallax barrier 33, and displays images including an image for the right eye observed (perceived) by the right eye of the observer and an image for the left eye observed by the left eye of the observer. 2D planar image or 3D stereoscopic image.

[0102] [About the configuration of the filter area]

[0103] In addition, although the above describes the case where only one edge side of the filter area of ​​each sub-pixel is provided along the y-direction, the light-shield areas may also be provided on both edge sides of the filter area in the y-direction.

[0104] In this case, as Image 6 as shown in e.g. figure 2 In each sub-pixel of the light modulation panel 32 shown, the light-shielding area is set to sandwich the light-filtering area. in addition, Image 6 neutralize figure 2 Parts corresponding to the respective parts in are denoted by the same reference numerals, and explanations thereof will be appropriately omitted.

[0105] In addition, in Image 6 A portion of the light modulating panel 32 and the switching liquid crystal layer 84 are shown in . exist Image 6 In , the horizontal direction, vertical direction and depth direction represent the x, y and z directions, respectively. also, Image 6 In t...

[0118] [About the configuration of the filter area]

[0119] Although the above describes the case of displaying a stereoscopic image including an image for the left eye and an image for the right eye, the stereoscopic image display device 11 may also display a multi-viewpoint stereoscopic image including a plurality of images of three or more viewpoints.

[0120] In this case, for example, as Figure 7 As shown, sub-pixels having color filters of R, G, and B colors are arranged on the filter surface of the light modulation panel 32 . in addition, Figure 7 neutralize figure 2 Parts corresponding to the respective parts in are denoted by the same reference numerals, and explanations thereof will be appropriately omitted. in addition, Figure 7 In , the horizontal direction, vertical direction and depth direction are assumed to be x, y and z directions, respectively. In addition, in Figure 7 In the example shown, the switching liquid crystal layer 84 , ie the parallax b...

Abstract

A display device includes: a display unit having a region which emits color light for displaying a stereoscopic image including images of a plurality of viewing points; and a separation unit that separates optically the images of the respective viewing points from each other so that the images of different viewing points are observed by different eyes of a viewer, wherein in a visible region on the display unit in which the image of a predetermined viewing point observed by the viewer is displayed, the region which emits the color light is present at each position of the stereoscopic image in a parallax direction regardless of a viewing position of the viewer who observes the stereoscopic image.

Description

technical field [0001] The present disclosure relates to a display device, and in particular, to a display device capable of suppressing occurrence of moiré. Background technique [0002] In the prior art, there are known display devices that display stereoscopic images using a parallax barrier method, a lenticular method, and the like, without the aid of special glasses. [0003] In such a display device, image display is performed such that images having different viewpoints are observed by different eyes of respective observers. However, in such a display device, since a pixel region of the display device displaying an image and a non-pixel region of the display device not displaying an image are perceived by a viewer, moiré is generated. That is, when the brightness difference between the pixel area and the non-pixel area is large, moiré is generated. [0004] Therefore, there has been proposed a technique for reducing moiré in which, when displaying a stereoscopic ima...
