Abstract

A display apparatus may include a display panel including a first area corresponding to a first resolution, a second area corresponding to a second resolution lower than the first resolution, and a third area corresponding to a third resolution lower than the second resolution, and a sensor disposed under the panel to overlap at least a portion of the third area. Pixels are disposed in the first area based on a first arrangement corresponding to a first pixel group including sub-pixels. Pixels are disposed in the second area based on a second arrangement corresponding to a second pixel group in which at least one of the sub-pixels of the first pixel group is omitted. Pixels are disposed in at least a part of the third area based on the first arrangement. A light transmittance portion is disposed in another part of the third area.

Claims (40)

1 . A display apparatus, comprising:

a panel including a first area corresponding to a first resolution, a second area corresponding to a second resolution lower than the first resolution, and a third area corresponding to a third resolution lower than the second resolution; and

a sensor disposed under the panel to overlap at least a portion of the third area,

wherein:

a plurality of pixels are disposed in the first area based on a first arrangement corresponding to a first pixel group including a plurality of sub-pixels;

a plurality of pixels are disposed in the second area based on a second arrangement corresponding to a second pixel group which is different from the first pixel group by omitting at least one sub-pixel from among the plurality of sub-pixels of the first pixel group;

a plurality of pixels are disposed in at least a part of the third area, based on the first arrangement;

a light transmittance portion is disposed in another part of the third area;

in the second area, a touch insulating layer overlapping at least one pixel among the plurality of pixels and a touch sensor overlapping at least a portion of the touch insulating layer are disposed; and

in the third area, the touch insulating layer extending from the second area is disposed.

2 . The display apparatus of claim 1 , wherein the plurality of sub-pixels of the first pixel group comprises one red sub-pixel, two green sub-pixels, and one blue sub-pixel.

3 . The display apparatus of claim 2 , wherein a shape of each of the red sub-pixel and the blue sub-pixel corresponds to a rectangle, and a shape of each of the two green sub-pixels corresponds to an ellipse or a circle.

4 . The display apparatus of claim 2 , wherein the second pixel group is a pixel group which is different from the first pixel group by omitting one green sub-pixel from among the plurality of sub-pixels of the first pixel group.

5 . The display apparatus of claim 2 , wherein the red sub-pixel and the blue sub-pixel are arranged in a first row along an x-axis direction, and the two green sub-pixels are arranged in a second row separated from the first row along the x-axis direction.

6 . The display apparatus of claim 2 , wherein the two green sub-pixels are arranged to be symmetrical with respect to a y-axis direction.

7 . The display apparatus of claim 2 , wherein one of the two green sub-pixels is arranged in a first diagonal direction with an inclination of 45° with respect to an x-axis direction, and the other one of the two green sub-pixels is arranged in a second diagonal direction with an inclination of −45° with respect to the x-axis direction.

8 . The display apparatus of claim 7 , wherein the second pixel group is a pixel group which is different from the first pixel group by omitting the one of the two green sub-pixels arranged in the first diagonal direction from among the plurality of sub-pixels of the first pixel group.

9 . The display apparatus of claim 7 , wherein the second pixel group is a pixel group which is different from the first pixel group by omitting the other one of the two green sub-pixels arranged in the second diagonal direction is omitted from among the plurality of sub-pixels of the first pixel group.

10 . The display apparatus of claim 1 , wherein the second area is disposed between the first area and the third area.

11 . The display apparatus of claim 1 , wherein the third area comprises a first pixel and a second pixel corresponding to the first arrangement, and the light transmittance portion is disposed between the first pixel and the second pixel.

12 . The display apparatus of claim 1 , wherein the sensor comprises at least one of an optical sensor, a camera sensor, an infrared sensor, and an ultraviolet sensor.

13 . The display apparatus of claim 1 , wherein a plane of the light transmittance portion corresponds to a circle or a polygon.

14 . The display apparatus of claim 1 , wherein a plane of the third area corresponds to a circle or a polygon.

15 . The display apparatus of claim 1 , wherein the second area surrounds a perimeter of the third area while being adjacent to the third area, and the first area surrounds a perimeter of the second area while being adjacent to the second area.

16 . The display apparatus of claim 1 , wherein a distance between the first area and the third area corresponds to a length of a unit pixel.

17 . A display panel, comprising:

a first area corresponding to a first resolution;

a second area corresponding to a second resolution lower than the first resolution; and

a third area corresponding to a third resolution lower than the second resolution,

wherein:

a plurality of pixels are disposed in the first area based on a first arrangement corresponding to a first pixel group including a plurality of sub-pixels;

a plurality of pixels are disposed in the second area based on a second arrangement corresponding to a second pixel group which is different from the first pixel group by omitting at least one sub-pixel from among the plurality of sub-pixels of the first pixel group;

a plurality of pixels are disposed in at least a part of the third area, based on the first arrangement;

a light transmittance portion is disposed in another part of the third area;

in the second area, a touch insulating layer overlapping at least one pixel among the plurality of pixels and a touch sensor overlapping at least a portion of the touch insulating layer are disposed; and

in the third area, the touch insulating layer extending from the second area is disposed.

18 . The display panel of claim 17 , wherein the plurality of sub-pixels of the first pixel group comprises one red sub-pixel, two green sub-pixels, and one blue sub-pixel.

19 . The display panel of claim 18 ,

wherein a shape of each of the red sub-pixel and the blue sub-pixel corresponds to a rectangle, and a shape of each of the two green sub-pixels corresponds to an ellipse or a circle.

20 . The display panel of claim 18 , wherein the second pixel group is a pixel group which is different from the first pixel group by omitting one green sub-pixel from among the plurality of sub-pixels of the first pixel group.
