Abstract

Provided are a display device and an electronic device that can suppress complication of an internal structure and facilitate effective reduction in an amount of processed data in consideration of human vision in a display region. A display device includes a display unit having a display region in which a plurality of pixel columns is arranged. Each of the plurality of pixel columns has a plurality of pixels arranged in a ring shape. In the display unit, the plurality of pixel columns is concentrically arranged along a plane direction of the display region, around, as a center, a reference position in the display region. In a case where a pixel column arranged at a predetermined position in the plurality of pixel columns is defined as a reference pixel column and a pixel forming the reference pixel column is defined as a reference pixel, a pixel forming a pixel column arranged on an outer side of the reference pixel column has a similar shape obtained by enlarging a shape of the reference pixel.

First claim

1 . A display device comprising:
a display unit having a display region in which a plurality of pixel columns is arranged, wherein each of a plurality of the pixel columns has a plurality of pixels arranged in a ring shape, in the display unit, a plurality of the pixel columns is concentrically arranged along a plane direction of the display region, the plurality of the pixel columns being arranged around, as a center, a reference position in the display region, and in a case where a pixel column among the pixel columns arranged at a predetermined position in a plurality of the pixel columns is defined as a reference pixel column, and each of the pixels forming the reference pixel column is defined as a reference pixel, each of the pixels forming each of the pixel columns arranged on an outer side of the reference pixel column has a similar shape obtained by enlarging a shape of the reference pixel.

2 . A display device comprising:
a display unit having a display region in which a plurality of pixel columns is arranged, wherein each of a plurality of the pixel columns has a plurality of pixels arranged in a ring shape, in the display unit, a plurality of the pixel columns is concentrically arranged along a plane direction of the display region, the plurality of the pixel columns being arranged around, as a center, a reference position in the display region, in a case where the display region is sectioned into a plurality of sectioned regions with a boundary between the pixel columns adjacent to each other, the pixels arranged in a same sectioned region among the sectioned regions have areas equal to each other, have lengths made equal to each other along a direction orthogonal to an alignment direction of the pixels, and have pitches made equal to each other, and among the sectioned regions adjacent to each other, a pitch of the pixels arranged in each of the sectioned regions arranged on an inner side is smaller than a pitch of the pixels arranged in each of the sectioned regions arranged on an outer side.

3 . The display device according to claim 1 , wherein
among the pixel columns adjacent to each other arranged on an outer side of the reference pixel column, a similarity ratio of a size of each of the pixels forming each of the pixel columns on an outer side to a size of each of the pixels forming each of the pixel columns on an inner side coincides with a similarity ratio of a size of each of the pixels forming each of the pixel columns adjacent to the reference pixel column on an outer side of the reference pixel column to a size of the reference pixel.

4 . The display device according to claim 1 , wherein
each of the pixels has sub-pixels of a plurality of color types, and for every color type of the sub-pixels, each of the sub-pixels arranged on an outer side of the reference pixel column has shape of a similar shape obtained by enlarging a shape of each of the sub-pixels forming the reference pixel.

5 . The display device according to claim 4 , wherein
for every color type of the sub-pixels, among the pixel columns adjacent to each other arranged on an outer side of the reference pixel column, a similarity ratio of a size of each of the sub-pixels forming each of the pixel columns on an outer side to a size of each of the sub-pixels forming each of the pixel columns on an inner side coincides with a reference similarity ratio that is defined as a similarity ratio of a size of each of the sub-pixels forming each of the pixel columns adjacent to the reference pixel column on an outer side of the reference pixel column to a size of each of the sub-pixels forming the reference pixel column, and the reference similarity ratio coincides between the sub-pixels of different color types.

6 . The display device according to claim 1 , wherein each of the pixels has sub-pixels of a plurality of color types, and
for every color type of the sub-pixels, among the pixel columns adjacent to each other arranged on an outer side of the reference pixel column, each of the sub-pixels forming one of the pixel columns is arranged at a position avoiding a position to be aligned, in an inner and outer direction, with a position of each of the sub-pixels forming another one of the pixel columns.

7 . The display device according to claim 1 , wherein
the reference pixel column is a pixel column among the pixel columns arranged at a position closest to the reference position.

8 . The display device according to claim 1 , wherein
inner pixels defined as the pixels arranged on an inner side of the reference pixel column have areas equal to each other, the inner pixels having lengths made equal to each other along a direction orthogonal to an alignment direction of the pixels in each of the pixel columns, and pitches of the inner pixels are equal to each other.

9 . The display device according to claim 8 , wherein
each of the pixels has sub-pixels of a plurality of color types, and for every color type of the sub-pixels, the sub-pixels forming the inner pixels have areas equal to each other, and have lengths made equal to each other along a direction orthogonal to an alignment direction of the pixels in each of the pixel columns.

10 . The display device according to claim 1 , wherein
each of the pixels has sub-pixels of a plurality of color types, and for every color type of the sub-pixels, among the pixel columns arranged adjacent to each other on an inner side of the reference pixel column, each of the sub-pixels forming one of the pixel columns is arranged at a position avoiding a position to be aligned, in an inner and outer direction, with a position of each of the sub-pixels forming another one of the pixel columns.

11 . The display device according to claim 2 , wherein a number of the sectioned regions is three or more.

12 . The display device according to claim 2 , wherein
each of the pixels has sub-pixels of a plurality of color types, and for every color type of the sub-pixels, the sub-pixels forming the pixels arranged in a same sectioned region among the sectioned regions have areas equal to each other and have lengths made equal to each other along a direction orthogonal to an alignment direction of the pixels in each of the pixel columns.

13 . The display device according to claim 1 , wherein
each of the pixels has a plurality of sub-pixels, and for one of the pixels, a plurality of the sub-pixels is arranged in each direction among an alignment direction of the pixels forming each of the pixel columns and a direction orthogonal to the alignment direction.
