Abstract

A display unit includes: a display section including a plurality of pixels and a black matrix formed between the adjacent pixels, and displaying n-number of perspective images having respective perspectives through allocating the n-number of perspective images to n-number of adjacent pixels, respectively, where n is an integer of 2 or larger; and a parallax device including a plurality of separation elements, two or more adjacent separation elements of the plurality of separation elements being arranged in correspondence with the n-number of adjacent pixels, the parallax device separating the n-number of perspective images into respective n-number of directions. A single specific separation element of the two or more adjacent separation elements allows a single specific perspective image of the plurality of perspective images to be viewed from a specific perspective position, and the rest allow the black matrix to be viewed from the specific perspective position.

Claims

1. A display unit comprising:

a display section including a plurality of pixels and a black matrix formed between the adjacent pixels, and displaying n-number of perspective images having respective perspectives through allocating the n-number of perspective images to n-number of adjacent pixels, respectively, thereby allowing each of the plurality of pixels to be allocated to any one of the n-number of perspective images, where n is an integer of 2 or larger; and

a parallax device including a plurality of separation elements, two or more adjacent separation elements of the plurality of separation elements being arranged in correspondence with the n-number of adjacent pixels, the parallax device separating the n-number of perspective images displayed on the display section into respective n-number of directions that are different from one another, wherein

a single specific separation element of the two or more adjacent separation elements allows a single specific perspective image of the plurality of perspective images to be viewed from a specific perspective position, and rest of the two or more adjacent separation elements allow the black matrix to be viewed from the specific perspective position.

2. The display unit according to claim 1, wherein the parallax device is disposed, at a distance from the display section, on a viewer side of the display section to oppose the display section, the distance being shorter or longer than a value of d represented by following expression,

d=Z·

P/(E+P)

where Z is a viewing distance, E is an interocular distance, and P is a pixel pitch.

3. The display unit according to claim 1, wherein the parallax device is arranged, having an arrangement interval of the adjacent separation elements, on a viewer side of the display section to oppose the display section, the arrangement interval being smaller than a value of L represented by following expression,

L=nP·

E/(E+P)

where n is number of the perspectives, E is an interocular distance, and P is a pixel pitch.

4. The display unit according to claim 1, wherein the parallax device is arranged, at a distance from the display section, on an opposite side of the display section from a viewer to oppose the display section, the distance being shorter or longer than a value of d represented by following expression,

d=Z·

P/(E−

P)

where Z is a viewing distance, E is an interocular distance, and P is a pixel pitch.

5. The display unit according to claim 1, wherein the parallax device is arranged, having an arrangement interval of the adjacent separation sections, on an opposite side of the display section from a viewer to oppose the display section, the arrangement interval being smaller than a value of L represented by following expression,

L=nP·

E/(E−

P)

where n is number of the perspectives, E is an interocular distance, and P is a pixel pitch.

6. The display unit according to claim 1, wherein the parallax device is a lenticular lens including a plurality of lens elements that serve as the separation elements.

7. The display unit according to claim 1, wherein the parallax device is a parallax barrier including a plurality of openings that serve as the separation elements.

8. An electronic apparatus with a display unit, the display unit comprising:

a display section including a plurality of pixels and a black matrix formed between the adjacent pixels, and displaying n-number of perspective images having respective perspectives through allocating the n-number of perspective images to n-number of adjacent pixels, respectively, thereby allowing each of the plurality of pixels to be allocated to any one of the n-number of perspective images, where n is an integer of 2 or larger; and

a parallax device including a plurality of separation elements, two or more adjacent separation elements of the plurality of separation elements being arranged in correspondence with the n-number of adjacent pixels, the parallax device separating the n-number of perspective images displayed on the display section into respective n-number of directions that are different from one another, wherein

a single specific separation element of the two or more adjacent separation elements allows a single specific perspective image of the plurality of perspective images to be viewed from a specific perspective position, and rest of the two or more adjacent separation elements allow the black matrix to be viewed from the specific perspective position.
