Abstract

An electronic device including a panel and a light control unit is provided. The panel includes a first light-emitting region and a transparent region disposed adjacent to the first light-emitting region. The light control unit is disposed on the panel, wherein the light control unit is overlapped with the first light-emitting region.

First claim

What is claimed is:

1. An electronic device, comprising:
a substrate;
a first display unit disposed on the substrate, the first display unit comprising a first light-emitting element and a second light-emitting element disposed adjacent to the first light-emitting element along a first direction, wherein the first light-emitting element and the second light-emitting element emits different colors;
a second display unit disposed on the substrate, the second display unit comprising a third light-emitting element and a fourth light-emitting element;
a third display unit disposed on the substrate, the third display unit comprising a fifth light-emitting element,
wherein the third light-emitting element and the fourth light-emitting element are disposed adjacently along the first direction, the third light-emitting element and the fifth light-emitting element are disposed adjacently along a second direction perpendicular to the first direction,
wherein the third light-emitting element and the fourth light-emitting element emits different colors, the second light-emitting element of the first display unit is disposed adjacent to the third light-emitting element of the second display unit along the first direction, and the second light-emitting element and the third light-emitting element are spaced apart by a space;
a transparent portion, wherein in the top view, the transparent portion is disposed between the second light-emitting element of the first display unit and the third light-emitting element of the second display unit, and the transparent portion is overlapped with the space between the second light-emitting element and the third light-emitting element; and
a light-shielding layer, wherein in the top view, a first part of the light-shielding layer is overlapped with the first display unit, a second part of the light-shielding layer is overlapped with the second display unit, wherein a third part of the light-shielding layer is overlapped with at least a portion of the transparent portion, and the first part of the light-shielding layer is connected to and extends to the third part of the light-shielding layer along the first direction,
wherein a length of the third part of the light-shielding layer along the first direction is greater than a width of the third part of the light-shielding layer along the second direction, and
wherein a fourth part of the light-shielding layer is overlapped with the third display unit, the second part of the light-shielding layer is connected to and extends to the fourth part of the light-shielding layer along the second direction.

2. The electronic device as claimed in claim 1 , wherein the light-emitting element is an organic light-emitting element.

3. The electronic device as claimed in claim 1 , wherein the first light-emitting element and the second light-emitting element of the first display unit emit colors of red, green, or blue.

4. The electronic device as claimed in claim 1 , wherein the third light-emitting element and the fourth light-emitting element of the second display unit emit colors of red, green, or blue.

5. The electronic device as claimed in claim 1 , further comprising:
a pixel definition layer comprising a first opening, wherein the first light-emitting element is disposed in the first opening.

6. The electronic device as claimed in claim 5 , wherein the pixel definition layer further comprises a second opening, and the transparent portion is disposed corresponding to the second opening.

7. The electronic device as claimed in claim 6 , wherein the pixel definition layer is patterned to include the first opening, the second opening and a plurality of pixel definition patterns, and
wherein the second light-emitting element and the transparent portion are separated by a pixel definition pattern of the plurality of pixel definition patterns.

8. The electronic device as claimed in claim 1 , further comprising:
a pixel definition layer comprising a second opening, and the transparent portion is disposed corresponding to the second opening.

9. The electronic device as claimed in claim 1 , wherein the first light-emitting element and the third light-emitting element emit a first color.

10. The electronic device as claimed in claim 9 , wherein the second light-emitting element and the fourth light-emitting element emit a second color different from the first color.

11. The electronic device as claimed in claim 1 , further comprising:
a light conversion layer, overlapping at least a portion of the light-shielding layer.

12. The electronic device as claimed in claim 1 , further comprising:
a first active device and a second active device disposed on the substrate;
a first electrode pattern disposed on and electrically connected to the first active device, wherein the second light-emitting element of the first display unit is disposed on the first electrode pattern; and
a second electrode pattern disposed on and electrically connected to the second active device, wherein the third light-emitting element of the second display unit is disposed on the second electrode pattern.
