Abstract

A display apparatus includes: a substrate; a first display area at which a plurality of main sub-pixels are on the substrate; and a second display area at which a base unit is on the substrate, the base unit comprising a plurality of pixel groups including auxiliary sub-pixels and transmission portions, wherein the pixel groups and the transmission portions are alternately arranged along a first direction, and auxiliary sub-pixels included in one pixel group among the pixel groups are provided in two rows, and a size of an emission area of a first auxiliary sub-pixel among the auxiliary sub-pixels is greater than a size of an emission area of a first main sub-pixel exhibiting a same color as that of the first auxiliary sub-pixel among the main sub-pixels.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate;
a first display area at which a plurality of main sub-pixels are on the substrate; and
a second display area at which a base unit is on the substrate, the base unit comprising a plurality of pixel groups including auxiliary sub-pixels and transmission portions,
wherein the pixel groups and the transmission portions are alternately arranged along a first direction, and auxiliary sub-pixels included in one pixel group among the pixel groups are provided in two rows, and
a size of an emission area of a first auxiliary sub-pixel among the auxiliary sub-pixels is greater than a size of an emission area of a first main sub-pixel exhibiting a same color as that of the first auxiliary sub-pixel among the main sub-pixels, while gaps and relative positions between the auxiliary sub-pixels of the pixel groups of the second display area are equal to corresponding gaps and relative positions between corresponding groups of sub-pixels of the main sub-pixels.

2. The display apparatus of claim 1 , wherein a number of the auxiliary sub-pixels included in the one pixel group among the pixel groups is three, and each of the auxiliary sub-pixels is arranged at a vertex of a virtual triangle.

3. The display apparatus of claim 1 , wherein a number of the auxiliary sub-pixels included in the base unit is ⅜ of a number of the main sub-pixels included in a corresponding unit having a same area as that of the base unit in the first display area.

4. The display apparatus of claim 1 , wherein the one pixel group and two of the transmission portions are arranged in a second direction intersecting the first direction.

5. The display apparatus of claim 1 , wherein a number of the auxiliary sub-pixels included in the one pixel group among the pixel groups is four, and each of the auxiliary sub-pixels is arranged at a vertex of a virtual rectangle.

6. The display apparatus of claim 5 , wherein the virtual rectangle is a parallelogram.

7. The display apparatus of claim 5 , wherein a number of the auxiliary sub-pixels included in the base unit is ¼ of a number of the main sub-pixels included in a corresponding unit having a same area as that of the base unit in the first display area.

8. The display apparatus of claim 5 , wherein the pixel groups are apart from each other in the base unit.

9. The display apparatus of claim 1 , wherein the transmission portions each have a circular shape.

10. The display apparatus of claim 1 , wherein opposite electrodes integrally provided in the main sub-pixels and the auxiliary sub-pixels are arranged in the first display area and the second display area, and the opposite electrodes each comprise an opening corresponding to one of the transmission portions.

11. The display apparatus of claim 1 , further comprising an inorganic insulating layer on the substrate,
wherein the inorganic insulating layer comprises openings corresponding to the transmission portions.

12. The display apparatus of claim 1 , further comprising a lower electrode layer between the substrate and the auxiliary sub-pixels,
wherein the lower electrode layer comprises lower holes corresponding to the transmission portions.

13. A display apparatus comprising:
a substrate comprising a first display area in which main sub-pixels are provided and a second display area in which a pixel group including auxiliary sub-pixels and a transmission portion are provided;
a first pixel electrode and a first emission layer, each configured to implement a first main sub-pixel among the main sub-pixels;
a second pixel electrode and a second emission layer, each configured to implement a first auxiliary sub-pixel exhibiting a same color as that of the first main sub-pixel among the auxiliary sub-pixels; and
an opposite electrode integrally arranged in the first display area and the second display area,
wherein the auxiliary sub-pixels included in the pixel group are provided in two rows, and
a size of an emission area of the first auxiliary sub-pixel is greater than a size of an emission area of the first main sub-pixel, while gaps and relative positions between the auxiliary sub-pixels of the pixel groups of the second display area are equal to corresponding gaps and relative positions between corresponding groups of sub-pixels of the main sub-pixels.

14. The display apparatus of claim 13 , further comprising a functional layer arranged between the first pixel electrode and the opposite electrode,
wherein the functional layer is arranged to correspond to the transmission portion.

15. The display apparatus of claim 13 , further comprising a lower electrode layer arranged between the substrate and the second pixel electrode,
wherein the lower electrode layer comprises lower holes corresponding to the transmission portion.

16. The display apparatus of claim 13 , further comprising a pixel defining layer comprising a first opening and a second opening configured to expose central portions of the first pixel electrode and the second pixel electrode, respectively,
wherein the emission area of the first main sub-pixel is defined by the first opening, and the emission area of the first auxiliary sub-pixel is defined by the second opening.

17. The display apparatus of claim 13 , further comprising an inorganic insulating layer arranged on the substrate,
wherein the inorganic insulating layer comprises openings corresponding to the transmission portion.

18. The display apparatus of claim 13 , wherein the first display area and the second display area are sealed by an encapsulation substrate arranged to face the substrate.

19. The display apparatus of claim 13 , further comprising a thin-film encapsulation layer comprising a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer, which are sequentially arranged on the opposite electrode.

20. The display apparatus of claim 13 , further comprising an image sensor arranged below the second display area.
