Abstract

A display panel and a display apparatus. The display panel includes: a base plate, an interconnection structure including at least two connection blocks and connection lines for connecting the at least two connection blocks; and a plurality of first sub-pixels located at a side of the interconnection structure away from the base plate and each including a first electrode, a first light-emitting structure and a second electrode stacked in sequence along a direction away from the interconnection structure; in which at least a part of the first electrode is located at a side of the connection block away from the base plate and electrically connected with the connection block, and an orthographic projection of the connection block on the base plate is at least partially staggered with an orthographic projection of the first light-emitting structure on the base plate.

Claims (26)

1 . A display panel, comprising:

a base plate;

an interconnection structure located at a side of the base plate and comprising at least two connection blocks and connection lines for connecting the at least two connection blocks; and

a plurality of first sub-pixels located at a side of the interconnection structure away from the base plate and each first sub-pixel comprising a first electrode, a first light-emitting structure and a second electrode stacked in sequence along a direction away from the interconnection structure, wherein:

at least a part of the first electrode is located at a side of the connection block away from the base plate and electrically connected with the connection block away from the base plate,

an orthographic projection of the connection block on the base plate is at least partially staggered with an orthographic projection of the first light-emitting structure on the base plate,

each connection block of the at least two connection blocks comprises a body portion and a hollow portion enclosed by the body portion, and

an orthographic projection of the hollow portion on the base plate at least partially overlaps the orthographic projection of the first light-emitting structure on the base plate.

2 . The display panel according to claim 1 , wherein the orthographic projection of the first light-emitting structure on the base plate is located within an orthographic projection of the first electrode on the base plate, and the orthographic projection of the connection block on the base plate is at least partially staggered with the orthographic projection of the first electrode on the base plate.

3 . The display panel according to claim 1 , wherein the orthographic projection of the first light-emitting structure on the base plate is located within the orthographic projection of the hollow portion on the base plate.

4 . The display panel according to claim 3 , wherein a distance between an edge of the orthographic projection of the first light-emitting structure on the base plate and an edge of the orthographic projection of the hollow portion on the base plate is in a range from 0.5 μm to 1.5 μm.

5 . The display panel according to claim 1 , wherein an orthographic projection of the body portion on the base plate at least partially overlaps an orthographic projection of the first electrode on the base plate.

6 . The display panel according to claim 1 , wherein the orthographic projection of the hollow portion on the base plate is located within an orthographic projection of the first electrode on the base plate.

7 . The display panel according to claim 6 , wherein a distance between an edge of the orthographic projection of the hollow portion on the base plate and an edge of the orthographic projection of the first electrode on the base plate is in a range from 1.0 μm to 3.5 μm.

8 . The display panel according to claim 1 , wherein an orthographic projection of the first electrode on the base plate is located within an area enclosed by an outer edge of the orthographic projection of the connection block on the base plate.

9 . The display panel according to claim 8 , wherein a distance between an edge of the orthographic projection of the first electrode on the base plate and the outer edge of the orthographic projection of the connection block on the base plate is in a range from 1.0 μm to 3.0 μm.

10 . The display panel according to claim 1 , wherein a material of at least one of the connection block and the connection line comprises a light-transmitting conductive material.

11 . The display panel according to claim 10 , wherein at least a portion of the connection block and the connection line are arranged in a same layer and made of a same material, and materials of the portion of the connection block and the connection line both comprise a light-transmitting material.

12 . The display panel according to claim 1 , further comprising:

a first display area and a second display area, wherein a light transmittance of the first display area is greater than a light transmittance of the second display area, and the interconnection structure and the first sub-pixels are located in the first display area; and

a first driving circuit located in the second display area, wherein the interconnection structure is connected with the first driving circuit through the connection lines.

13 . The display panel according to claim 12 , further comprising:

second sub-pixels located in the second display area; and

a second driving circuit configured to drive the second sub-pixels to display, wherein each second sub-pixel comprises a third electrode, a fourth electrode, and a second light-emitting structure located between the third electrode and the fourth electrode, and each third electrode is directly connected with the second driving circuit through a signal line.

14 . The display panel according to claim 1 , wherein the connection line is configured to connect four connection blocks, and first light-emitting structures corresponding to the four connection blocks emit lights of a same color.

15 . A display apparatus, comprising the display panel according to claim 1 .
