Abstract

An electronic device includes: a front plate; a display panel on a rear surface of the front plate, the display panel having at least one camera hole therein; and a camera module including: a lens barrel including a head portion protruding toward the front plate and a protruding barrel space adjacent to the head portion, wherein the head portion has an optical opening therein; and a plurality of lenses aligned along an optical axis within the lens barrel, wherein the plurality of lenses includes a first nearest lens from an object-side and is in the protruding barrel space, and an outer diameter of a rib of the first nearest lens from the object-side is smaller than an outer diameter of the head portion.

First claim

What is claimed is:

1 . An electronic device comprising:
a front plate; a display panel on a rear surface of the front plate, the display panel having at least one camera hole therein; and a camera module comprising:
a lens barrel comprising a head portion protruding toward the front plate and a protruding barrel space adjacent to the head portion, wherein the head portion has an optical opening therein, and
a plurality of lenses aligned along an optical axis within the lens barrel,
wherein the plurality of lenses comprises a first nearest lens from an object-side and is in the protruding barrel space, and wherein an outer diameter of a rib of the first nearest lens from the object-side is smaller than an outer diameter of the head portion.

2 . The electronic device of claim 1 , wherein the plurality of lenses further comprises a second nearest lens from the object-side that is adjacent to the first nearest lens, and
wherein the outer diameter of the head portion is smaller than an outer diameter of a rib of the second nearest lens.

3 . The electronic device of claim 2 , wherein the at least one camera hole has a diameter that is greater than the outer diameter of the head portion and smaller than the outer diameter including the rib of the second nearest lens.

4 . The electronic device of claim 3 , wherein the first nearest lens contacts an inner surface of the lens barrel at a first contact point and a second contact point, and contacts the second nearest lens at a third contact point.

5 . The electronic device of claim 4 , wherein the second contact point is at a largest outer diameter of the first nearest lens.

6 . The electronic device of claim 4 , wherein the first contact point is in a non-effective diameter portion of an object-side surface of the first nearest lens, and
wherein the third contact point is in a non-effective diameter portion of an image-side surface of the first nearest lens.

7 . The electronic device of claim 4 , wherein each of a distance from the optical axis to the first contact point and a distance from the optical axis to the third contact point is smaller than a distance from the optical axis to the second contact point.

8 . The electronic device of claim 4 , wherein a contact length between the inner surface of the lens barrel and the first contact point of the first nearest lens is about 0.1 mm or less, a contact length between the inner surface of the lens barrel and the second contact point is about 0.1 mm or less, and a contact length between the second nearest lens from the object-side and the third contact point is about 0.1 mm or less.

9 . The electronic device of claim 4 , wherein the plurality of lenses further comprises a third nearest lens from the object-side that is adjacent to the second nearest lens, and
wherein the second nearest lens contacts the first nearest lens, contacts the inner surface of the lens barrel, and contacts the third nearest lens.

10 . The electronic device of claim 9 , wherein the second nearest lens contacts the first nearest lens at a fourth contact point at a position adjacent to the protruding barrel space in the lens barrel, contacts the inner surface of the lens barrel at a fifth contact point, and contacts the third nearest lens at a sixth contact point.

11 . The electronic device of claim 10 , wherein the fifth contact point is at a largest outer diameter of the second nearest lens.

12 . The electronic device of claim 10 , wherein the fourth contact point is in a non-effective diameter portion of an object-side surface of the second nearest lens, and
wherein the sixth contact point is in a non-effective diameter portion of an image-side surface of the second nearest lens.

13 . The electronic device of claim 10 , wherein each of a distance from the optical axis to the fourth contact point and a distance from the optical axis to the sixth contact point is each smaller than a distance from the optical axis to the fifth contact point.

14 . The electronic device of claim 10 , wherein a distance from the optical axis to the fourth contact point is smaller than a distance from the optical axis to the second contact point, and a distance from the optical axis to the sixth contact point is greater than the distance from the optical axis to the second contact point.

15 . The electronic device of claim 1 , wherein a field of view of the camera module is 90 degrees or greater.

16 . An electronic device comprising:
a front plate; a display panel on a rear surface of the front plate, the display panel having at least one camera hole therein; and a camera module comprising: a lens barrel comprising a head portion protruding toward the front plate and a protruding barrel space adjacent to the head portion, wherein the head portion has an optical opening therein, and a plurality of lenses aligned along an optical axis within the lens barrel, wherein the plurality of lenses comprises a first nearest lens from an object-side, a second nearest lens from the object-side, and a third nearest lens from the object-side wherein the first nearest lens contacts an inner surface of the lens barrel through a first contact point and a second contact point, and contacts the second nearest lens through a third contact point, wherein the second nearest lens contacts the first nearest lens through a fourth contact point, the inner surface of the lens barrel through a fifth contact point, and the third nearest lens through a sixth contact point, wherein each of a distance from the optical axis to the first contact point and a distance from the optical axis to the third contact point is smaller than the distance from the optical axis to the second contact point, wherein a distance from the optical axis to the fourth contact point is smaller than the distance from the optical axis to the second contact point, and wherein a distance from the optical axis to the sixth contact point is greater than the distance from the optical axis to the second contact point.

17 . The electronic device of claim 16 , wherein the outer diameter of the head portion of the lens barrel may be smaller than an outer diameter including a rib of the second nearest lens from the object-side.

18 . The electronic device of claim 16 , wherein the outer diameter of the head portion of the lens barrel is smaller than an outer diameter including a rib of the second nearest lens from the object-side.

19 . The electronic device of claim 16 , wherein the diameter of the at least one camera hole is greater than the outer diameter of the head portion of the lens barrel and smaller than the outer diameter including the rib of the second nearest lens from the object-side.

20 . The electronic device of claim 16 , wherein the FOV of the camera module is 90 degrees or greater.
