Description

[Technical Field]

[0001] Embodiments of the disclosure described herein relate to an electronic device including a camera module for taking an image through at least a portion of a display.[Background Art]

[0002] A portable electronic device, such as a smartphone or a tablet computer, provides a wide screen by increasing the size of a display region while minimizing a bezel region. An image sensor for implementing a camera (e.g., a camera module), an illuminance sensor for sensing illuminance, and a fingerprint recognition sensor for fingerprint verification, together with a display device (e.g., a display), may be disposed on a front surface of the portable electronic device.

[0003] KR 2017 0126171 A discloses a lens assembly comprising a base having an inner through-hole, a second lens unit disposed in the through-hole, a second lens unit spaced from the first lens unit to be disposed in the through-hole, and a liquid lens unit disposed between the first lens unit and the second lens unit. The base is able to comprise an insertion tool where the liquid lens unit is inserted.

[0004] EP 3 508 911 A1 discloses a camera module comprising a holder; a first lens part disposed at an upper part of the holder, a second lens part disposed at an lower part of the holder, a liquid lens coupled to the holder and disposed between the first lens part and the second lens part, a substrate electrically connected to the liquid lens, and an image sensor disposed in the optical axis direction of the liquid lens and mounted on the substrate. A distance from a rear surface of the first lens part to a front surface of the second lens part on an optical axis is 1.8-2.1 times the thickness of the liquid lens.[Disclosure][Technical Problem]

[0005] In the electronic device, to use the display region to the maximum, the image sensor (e.g., a camera module) may be disposed to at least partially vertically overlap the display. To arrange the image sensor such that the image sensor vertically overlaps the display, the display may include a camera hole corresponding to the position of the image sensor. To minimize the size of the camera hole, an aperture stop may be disposed in the display. However, when a lens assembly vertically moves toward the display for auto focus (AF) in the state in which the aperture stop is disposed in the display, optical characteristics of the lens assembly may be changed.

[0006] Embodiments of the disclosure provide an electronic device including a camera module for performing AF through a variable lens without movement of a lens assembly, with an aperture stop disposed in a display.[Technical Solution]

[0007] The invention is defined by the appended claims.

[0008] An electronic device according to an embodiment of the disclosure includes a camera module including at least one lens, a display including a camera exposure region that at least partially overlaps the at least one lens when viewed in a direction corresponding to an optical axis of the at least one lens, and an aperture stop disposed in the camera exposure region. The camera module includes a variable lens having a curvature changed based on supplied electrical energy, a first lens that is disposed between the display and the variable lens and that has a positive focal length, and a second lens that is disposed farther away from the display than the first lens and that has a negative focal length. A ratio between a first distance from the aperture stop to the variable lens and a second distance from the first lens to the variable lens is set to have a magnitude within a specified range.

[0009] An electronic device according to an embodiment of the disclosure includes a first lens assembly including a first lens having a positive focal length, a second lens assembly including a second lens having a negative focal length, a variable lens that is disposed between the first lens assembly and the second lens assembly and that has a curvature changed based on supplied electrical energy, a display including a camera exposure region that at least partially overlaps the first lens when viewed in a direction corresponding to an optical axis of the first lens, and an aperture stop disposed in the camera exposure region. A ratio between a first distance from the aperture stop to the variable lens and a second distance from the first lens to the variable lens is set to have a magnitude within a specified range.[Advantageous Effects]

[0010] According to the embodiments of the disclosure, the aperture stop is located in the display, and thus the size of the camera hole may be minimized.

[0011] According to the embodiments of the disclosure, by performing auto focus (AF) through the variable lens without movement of the lens assembly, optical characteristics of the camera module may remain constant, with the aperture stop disposed in the display.

According to an embodiment, the first surface may be formed by a first plate (or, a front plate) 110 (e.g., a glass plate including various coating layers, or a polymer plate), at least a portion of which is substantially transparent. The second surface may be formed by a second plate (or, a back plate) that is substantially opaque. The second plate may be formed of, for example, coated or colored glass, ceramic, a polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the aforementioned materials.

In some embodiments, the back plate and the side bezel structure may be integrally formed with each other and may include the same material (e.g., a metallic material such as aluminum).

[0017] According to an embodiment, the electronic device 100 may include a printed circuit board therein. For example, a processor (e.g., a processor 1320 of FIG. 13 to be described below), a memory, and / or an interface may be mounted on the printed circuit board. The processor may include, for example, one or more of a central processing unit, an application processor, a graphic processing unit, an image signal processor, a sensor hub processor, or a communication processor. The memory may include, for example, a volatile memory or a non-volatile memory.

[0018] According to an embodiment, the electronic device 100 may include a display panel 120. For example, the display panel 120 may be coupled to one surface of a support member 130 and may be disposed between the first plate 110 and the support member 130. The first plate 110 may include the camera exposure region 110a formed in a position corresponding to the camera module 200 when the first plate 110 is viewed in the Z-axis direction. The camera exposure region 110a may be formed through the first plate 110, the display panel 120, and the support member 130. For example, the camera exposure region 110a may form an optical hole. A portion of the display panel 120 or the support member 130 that corresponds to the camera exposure region 110a may be filled with a transparent material 120a, or may have a through-hole formed therein. An aperture stop 201 is disposed in the camera exposure region 110a. For example, the aperture stop 201 may be disposed on one surface of the transparent material 120a or one surface of the first plate 110. The aperture stop 201 may be disposed to correspond to an optical axis of lenses (e.g., a first lens group 212 and a second lens group 242).

[0019] According to an embodiment, the camera module 200 may include the first lens assembly 210, a variable lens 220 (e.g., an active lens or a tunable lens), a first circuit board 230, the second lens assembly 240, a filter 250, the image sensor 260, a second circuit board 270, or a connector 280.

[0020] According to an embodiment, the first lens assembly 210 may include a first lens housing 211 and the first lens group 212 including at least one lens. The second lens assembly 240 may include a second lens housing 241 and the second lens group 242 including at least one lens. For example, the aperture stop 201, the first lens group 212, the variable lens 220, and the second lens group 242 may be disposed with respect to the same optical axis (e.g., the Z-axis) (or, to have the same optical axis).

[0021] According to an embodiment, the first lens group 212, the variable lens 220, and the second lens group 242 may collect light incident from the outside and may transmit the collected light to the image sensor 260 disposed under the second lens housing 241. For example, the first lens group 212 may be constituted by one or more lenses. For example, the first lens group 212 may include at least one lens that is convex toward the aperture stop 201 (or the camera exposure region 110a) and has a positive focal length. The second lens group 242 may be constituted by one or more lenses. For example, the second lens group 242 may include at least one lens that is concave toward the aperture stop 201 (or the camera exposure region 110a) and has a negative focal length. In another example, the second lens group 242 may include four or more lenses having a negative focal length. The first lens group 212, the variable lens 220, and the second lens group 242 may be disposed in positions corresponding to the camera exposure region 110a. The first lens assembly 210 may be coupled (or, fixed) to the second lens assembly 240.

[0022] According to an embodiment, the variable lens 220 may be disposed between the first lens assembly 210 and the second lens assembly 240. For example, the variable lens 220 may have a curvature changed based on supplied electrical energy and may serve as a lens. For example, the variable lens 220 may include a liquid lens.

[0023] According to an embodiment, the variable lens 220 may be connected, through the first circuit board 230, to the processor operationally connected with the camera module 200. For example, the variable lens 220 may be connected to the first circuit board 230. The first circuit board 230 may be connected to the second circuit board 270 through one surface of the second lens assembly 240. The second circuit board 270 may be connected to the connector 280 through a flexible printed circuit board (FPCB). The connector 280 may be operationally connected with the processor. The processor may change the curvature of the variable lens 220 through an electrical signal (e.g., voltage or current). The processor may perform an auto focus (AF) operation by controlling the variable lens. For example, the first circuit board 230 may include an FPCB.

[0024] According to an embodiment, the filter 250 may be disposed between the second lens assembly 240 and the image sensor 260. For example, the filter 250 may include an infrared filter that filters an infrared region from light incident through the lenses. For example, the filter 250 may be disposed between the second lens assembly 240 and the image sensor 260. In another example, the filter 250 may be disposed between the variable lens 220 and the second lens assembly 240. According to various embodiments, the filter 250 may be omitted from the camera module 200.

[0025] According to an embodiment, image data obtained by the image sensor 260 may be transmitted to the processor. For example, the image sensor 260 may be mounted on the second circuit board 270. The second circuit board 270 may be connected to the connector 280 through the FPCB. The connector 280 may be operationally connected with the processor.

[0026] According to an embodiment, the lenses included in the camera module 200 may satisfy Equation 1. For example, the aperture stop 201 may be spaced apart from a first lens surface included in the first lens assembly 210 (a lens surface closest to the display panel 120) by a specified distance. For example, the distance between the aperture stop 201 and the variable lens 220 (or a first surface of the variable lens 220 (a surface closest to the display panel 120)) in the Z-axis direction may have a first length L1. The distance between the first lens surface of the first lens assembly 210 and the variable lens 220 (or the first surface of the variable lens 220) in the Z-axis direction may have a second length L2. The first length L1 and the second length L2 may have a relationship as in Equation 1. 1.1 ≤ L 1 L 2 ≤ 2.0

[0027] According to an embodiment, the lenses included in the camera module 200 may satisfy Equation 2. For example, the size (e.g., diameter) of the aperture stop 201 may be smaller than the effective diameter of the variable lens 220. The effective diameter may be defined as the distance between two points at which the border where the curvature of the lens starts and a straight line passing through the center of the lens meet. For example, the size of the aperture stop 201 may have a third length L3. The effective diameter of the variable lens 220 may have a fourth length L4. The third length L3 and the fourth length L4 may have a relationship as in Equation 2. 0.2 ≤ L 3 L 4 ≤ 1.0

[0028] According to an embodiment, the lenses included in the camera module 200 may satisfy Equation 3. For example, the ratio of the effective diameter of a first lens (e.g., a lens closest to the display module 120) among the lenses included in the first lens assembly 210 to the diagonal length of the image sensor 260 may have a specified ratio. For example, the effective diameter of the first lens may have a fifth length L5. The diagonal length of the image sensor 260 may have a sixth length L6. The fifth length L5 and the sixth length L6 may have a relationship as in Equation 3. 0.2 ≤ L 5 L 6 ≤ 0.8

[0029] According to an embodiment, the lenses included in the camera module 200 may satisfy Equation 4. For example, as in Equation 4, the ratio of the distance (e.g., the first length L1) between the aperture stop 201 and the variable lens 220 in the Z-axis direction to the diagonal length (e.g., the sixth length L6) of the image sensor 260 may have a specified ratio. 0.3 ≤ L 1 L 6 ≤ 2.0

[0030] According to an embodiment, the lenses included in the camera module 200 may satisfy Equation 5. For example, the ratio of the thickness of the center of the variable lens 220 to the distance from the aperture stop 201 to an image surface of the image sensor 260 may have a specified ratio. For example, the thickness of the center of the variable lens 220 may have a seventh length L7. The distance from the aperture stop 201 to the image surface of the image sensor 260 may have an eighth length L8. The seventh length L7 and the eighth length L8 may have a relationship as in Equation 5. 0.02 ≤ L 7 L 8 ≤ 0.3

[0031] According to an embodiment, the lenses included in the camera module 200 may satisfy Equation 6. In Equation 6, f may represent the composite focal length of the lenses included in the camera module 200, and fmax may represent the focal length of a lens having the highest focal length among the lenses included in the camera module 200. 0.3 < f fmax < 3.0

[0032] According to an embodiment, the camera module 200 may include at least one aspheric lens including at least one point of inflection. According to various embodiments, the camera module 200 may include three or more injection-molded plastic aspheric lenses.

[0033] According to various embodiments (not illustrated), the electronic device 100 may include a rollable display. The camera module 200 may be disposed to vertically overlap a portion of the rollable display. In the rollable display, a partial region of a glass window (e.g., the first plate 110) constituting the display may be deformed due to repeated operations such as extension or retraction. The camera module 200 may control the curvature of the variable lens 220 in response to the deformation of the glass window and may obtain a constant-quality image irrespective of the deformation of the glass window.

A portion of the through-hole that corresponds to the support member 130 may be an empty space 420b. The aperture stop 201 may be disposed in a band shape on one surface of the transparent member 410.

[0037] Referring to a third embodiment 403 of FIG. 4, a through-hole may be formed through the display panel 120 and the support member 130 that correspond to the camera exposure region 110a. The through-hole may be an empty space 430. The aperture stop 201 may be disposed in a band shape on one surface of the first plate 110.
