Abstract: An optical device may include a lens assembly having multiple lenses aligned along an optical axis direction from an object-side toward an image-side, and a lens barrel configured to at least partially surround the lens assembly. Among the multiple lenses included the lens assembly, at least one of lenses positioned between the first lens and the last lens from the object-side may be configured such that a ratio of a height from a starting point of a non-effective diameter of the lens to a starting point of a seat surface of the lens, and a distance from the starting point of the non-effective diameter to a portion of the lens in contact with the inner surface (the outer diameter) of the barrel exceeds 0.5. The lens assembly may be various according to an embodiment. In addition, a lens assembly and an electronic device including the same according to the embodiment may be provided.

Abstract: According to an embodiment of the disclosure, a lens assembly and/or an electronic device including the same may include an image sensor and three lenses sequentially arranged along an optical axis from an object side to an image sensor side. In the three lenses, a first lens disposed on the object side may include an object side surface convex toward the object and an image sensor side surface convex toward the image sensor while having positive power, a second lens may include an object side surface concave toward the image sensor while having negative power, and a third lens may have negative power. The lens assembly may satisfy the condition below: 0.1

Abstract: An electronic device is provided. The electronic device includes a housing, a display panel, and a camera device. The housing may have an inner space. The display panel may be disposed in the inner space of the housing to be visible from an outside and may include a transmission area formed as a part of an active area thereof. The camera device may be disposed under the display panel such that the transmission area of the display panel is overlapped with an angle of view of the camera device. The transmission area contains a plurality of pixels or a plurality of wirings having an arrangement density lower than in a surrounding active area when the display panel is viewed from above. The display panel may include an opaque layer disposed thereunder, having a plurality of openings, and overlapped with the transmission area when the display panel is viewed from above.

Abstract: Disclosed herein is a lens assembly that includes an aperture stop and at least three lenses. The first lens is disposed closer to the image sensor than the aperture stop, the first lens including two convex surfaces. The second lens is disposed closer to the image sensor than the first lens, and includes convex and concave surfaces. And the third lens is disposed closer to the image sensor than the second lens. The lens assembly meets Equation 1: 0.1≤CT15/StopL≤0.4 wherein “CT15” denotes a distance between the object-side surface of the first lens and the object-side surface of the third lens measured along the optical axis, and “StopL” denotes a distance between an image forming surface of the image sensor and the aperture stop measured along the optical axis. Other various embodiments are also disclosed.
