Embodiment approach 1

[0088] The display device 10 according to the present embodiment will be described below. The display device 10 according to the present embodiment is provided with the bar-shaped light-shielding region 136 forming a partially shielded light emitted from the display panel 11 (refer to Figure 16A The first shading area 136a in and Figure 16B The second light shielding area 136b) in the light shielding unit 13 (refer to Figure 14 ), and dynamically switch the extending direction of the light-shielding region 136 between the first direction x and the second direction y according to the switching of the display direction of the image. This switching prevents color moiré from occurring.

[0089] Figure 11A and Figure 11B It is a perspective view of the electronic device 1 having the display device 10 . Figure 11A It shows the state where the electronic device 1 is placed in a horizontal posture, Figure 11B A state where the electronic device 1 is placed in a vertical p...

Embodiment approach 2

[0132] In Embodiment 1, two viewpoints were described as an example, but the shading control in Embodiment 1 can be applied to more than two viewpoints, not limited to two viewpoints. In the present embodiment, a case is described in which the display device 10 performs image display for multi-viewpoints of more than two viewpoints. It should be noted that, since the same reference numerals are used in the drawings, the contents that overlap with Embodiment 1 will not be described again.

[0133] Before describing the present embodiment, related technologies related to image display for multi-viewpoints and problems thereof will be described. Figure 26A and Figure 26B Image display for multiple viewpoints is depicted. Figure 26A and Figure 26B A case where image display for two viewpoints is performed similarly to Embodiment 1 and a case where image display for eight viewpoints is performed differently from Embodiment 1 are respectively shown.

Embodiment approach 3

[0153] In the present embodiment, a case where 3D display is performed according to the position of the observer will be described.

[0154] Figure 34 It is a block diagram showing an example of the configuration of the display device 10 . The display device 10 according to the present embodiment is provided with the position detection unit 28 . The position detection unit 28 includes, for example, a camera or the like that images the space in front of the electronic device 1 , recognizes the position of the observer's eyes through image recognition processing, and applies the recognition result to the control unit 21 .

[0155] Figure 35A and Figure 35B The outline of the 3D display process according to the third embodiment is shown. In the naked-eye 3D display method, the optimal position where the observer observes the parallax image is usually set in advance. For example, as Figure 35A As shown, the optimal viewing position is set to a position in front of the ce...

Abstract

The invention relates to a display device, electronic equipment and a display method. A display device (10), comprising: a display panel including a plurality of pixels arranged along a first direction and a second direction; an allocation unit configured to display pixels corresponding to each of a plurality of viewpoints light emitted by each pixel of the parallax image; and a light shielding unit disposed between the display panel and the distribution unit. The distributing unit distributes the light emitted from each pixel to a plurality of viewpoints along the first direction in a first display state in which the display panel displays a parallax image, or stops distributing the emitted light in a second display state in which the display panel displays a planar image . The light-shielding unit forms a plurality of first light-shielding regions respectively extending along the second direction along the first direction in the case of the first display state and blocks a part of the emitted light in the case of the second display state, and stops forming the first light-shielding regions in the case of the second display state. shaded area.

Description

technical field [0001] The invention relates to a display device, electronic equipment and a display method. Background technique [0002] Display devices that display three-dimensional stereoscopic images without using glasses for three-dimensional stereoscopic display have been proposed (for example, Japanese Patent Application Laid-Open No. 2013-55695 and Japanese Patent Application Laid-Open No. 2014-41355). Furthermore, display devices having a function of displaying three-dimensional stereoscopic images or two-dimensional images (hereinafter appropriately referred to as 3D display devices) have been proposed. Three-dimensional stereoscopic image display is called "3D (three-dimensional) display", and two-dimensional image display is called "2D display". [0003] With a 3D display device, at the time of 2D display, image quality degradation may occur due to unevenness in display colors (so-called color moiré). Contents of the invention [0004] An object of one aspe...
