Description

Technology Field

[0001] Various embodiments of the present invention relate to an electronic device including a display and a camera device. Background Technology

[0003] Electronic devices, for example, portable electronic devices, are released in various sizes depending on their functions and user preferences, and may include a large touch screen display to ensure wide visibility and ease of operation. The electronic device may include at least one camera device. For example, the electronic device may include at least one camera device positioned around the display or through at least a part of the display. The problem to be solved

[0005] The electronic device may include a display positioned so as to be visible from the outside through at least a portion of a cover member (e.g., a front plate, a glass window, or a front cover). To meet the requirements for a large screen, the display area may be gradually expanded so as to be exposed through substantially the entire area of ​​the cover member (e.g., a front cover). In response to the expansion of the display area, the arrangement structure of various electronic components positioned through the cover member, such as at least one camera device, may also be modified accordingly. If the camera device is positioned in an area of ​​the cover member other than the display area (e.g., a black matrix (BM) area or an inactive area), there may be a limit to the expansion of the display area.

[0006] To expand the display area, the camera device may be placed below the active area of ​​the display. In this case, the area corresponding to the field of view of the camera device of the display may include a transparent area in which pixels and / or wiring are arranged at a lower density than the surroundings to perform the display function and simultaneously satisfy the transmittance required by the camera device.

[0007] However, this transparent area of ​​the display has a low placement density, and diffraction with various frequencies occurs due to pixels and / or wiring having an irregular arrangement structure. This results in the modulation transfer function (MTF) being non-linear and fluctuating as a sine wave (generally a decrease) due to destructive interference caused by the diffraction of light sources with various frequencies. Due to this cause, if a camera device is placed below the transparent area, the image quality of the camera device may be degraded.

[0008] According to various embodiments of the present invention, an electronic device including a display and a camera device can be provided.

[0009] According to various embodiments, an electronic device including a display and a camera device configured to improve image quality by controlling the diffraction characteristics of light entering from a transmission region can be provided. means of solving the problem

[0011] According to various embodiments, the electronic device comprises a housing, a display panel including a transparent area disposed in an internal space of the housing so as to be visible from the outside and disposed in at least a portion of an active area, and a camera device disposed below the display panel such that the transparent area overlaps with the viewing angle, wherein the transparent area includes a plurality of pixels and / or a plurality of wires having a lower arrangement density than a surrounding active area when viewed from above the display panel, and the display panel may include an opaque layer comprising a plurality of openings disposed below the display panel that overlap with the transparent area when viewed from above the display panel. Effects of the invention

[0013] Various embodiments of the present invention provide an opaque layer having a plurality of openings under a display panel, and by controlling the shape, size, arrangement density, and / or arrangement spacing of the plurality of openings, excellent MTF characteristics are exhibited, thereby inducing a reduction in the degree of diffraction of light entering from a transmission area, which can help provide an image of excellent quality through a camera device.

[0054] According to various embodiments, the camera device (500) may include a camera housing (510), a lens housing (520) disposed in the internal space (5101) of the camera housing (510) and protruding at least partially in the display direction (e.g., direction ①), a plurality of lenses (530: 531, 532, 533, 534) disposed at regular intervals in the internal space (5201) of the lens housing (520), and at least one image sensor (540) disposed in the internal space (5101) of the camera housing (510) to acquire at least a portion of the light that has passed through the plurality of lenses (530). According to one embodiment, when the camera device (500) includes an AF (auto focus) function, the lens housing (520) may be movable so that the distance from the display panel (431) is varied through a predetermined driving unit in the camera housing (510). According to one embodiment, a separate driving unit may be provided to change the position of at least one of the plurality of lenses (530) so that the camera device (500) performs an AF function. In another embodiment, the camera housing (510) of the camera device (500) may be omitted, and the lens housing (520) may be placed directly on the first support member (311) through a predetermined alignment process. According to one embodiment, in the case where it is placed directly on the first support member (311), the camera housing (510) may be omitted to reduce the camera placement space, and the lens housing (520) may be placed to be attached to one side of the first support member (311). According to one embodiment, the camera device (500) may be attached to the back surface of the first support member (311) through an adhesive member (312) (e.g., a bonding member or a tape member) after being aligned through the through hole (301) of the first support member (311).

In another embodiment, the opening (4321) formed in the POL (432) may be filled with a material (e.g., index matching material) to match the refractive index due to increased interfacial reflection. In another embodiment, the area corresponding to the plurality of lenses (530) of the POL (432) may not have an opening (4321) formed and may have a high transmittance. For example, at least some area of ​​the POL (432) (e.g., the area corresponding to the plurality of lenses (530)) may be formed of a material having a transmittance different from that of other areas of the POL (432), or may be composed of other materials capable of increasing transmittance.

According to one embodiment, the display panel (431) may include a transparent area (A1) that is positioned in an area that overlaps with the angle of view (θ) of a camera device (500) positioned below it, at least in part of the active area, when the display (400) is viewed from above. According to one embodiment, the transparent area (A1) may be formed to have a higher transmittance than the surrounding active area (A2). For example, the transparent area (A2) may be formed to have a transmittance in the range of 5% to 20% through the rearrangement of a plurality of pixels and / or wiring within the display panel (431). According to various embodiments, the transparent area (A1) may include an opaque layer (e.g., opaque layer (460) of FIG. 6) that includes a plurality of openings (e.g., openings (461) of FIG. 6) positioned below the display panel (431). According to one embodiment, the transmittance of the transmission area (A1) can be determined by controlling at least one of the shape, size, placement density, and / or placement spacing of a plurality of openings (e.g., openings (461) in FIG. 6) formed in an opaque layer (e.g., opaque layer (460) in FIG. 6).

[0060] FIG. 6 is a partial cross-sectional view of a display panel with an enlarged area of ​​FIG. 5b according to various embodiments of the present invention.

[0061] Referring to FIG. 6, the display panel (431) may include a substrate layer (431a), an intermediate layer (431b) laminated on the substrate layer (431a), and a protective layer (431c) laminated on the intermediate layer (431b).

According to one embodiment, the organic light-emitting layer may be disposed between a pair of common layers that are stacked vertically. According to one embodiment, one common layer may include a hole injection layer (HIL) and / or a hole transport layer (HTL). According to one embodiment, the other common layer may include an electron transport layer (ETL) and / or an electron injection layer (EIL). However, it is not limited thereto, and the common layer may include various additional functional layers while including the organic light-emitting layer. According to one embodiment, the first to third colors described above may each be red, green, and blue. In another embodiment, various combinations of other colors other than the combination of red, green, and blue may be used, provided that white light can be emitted.

[0064] According to various embodiments, the counter electrode (4313) may be composed of a transparent or translucent electrode, may include one or more materials selected from silver (Ag), aluminum (Al), magnesium (Mg), lithium (Li), calcium (Ca), copper (Cu), LiF / Ca, LiF / Al, MgAg, or CaAg, and may be formed as a thin film having a thickness of several to tens of nanometers. According to one embodiment, light emitted from the first to third organic light-emitting layers included in the first to third organic layers (4312a, 4312b, 4312c) may be emitted directly or reflected by the first to third pixel electrodes (4311a, 4311b, 4311c) toward the counter electrode (4313).

[0065] According to various embodiments, the substrate layer (431a) may include an electrical connection member electrically connected to each of the first to third pixel electrodes (4311a, 4311b, 4311c). According to one embodiment, the electrical connection member may include a thin film transistor (TFT) or a low temperature passivation transistor (LTPS). According to one embodiment, an encap layer (431c) may be disposed on top of the opposing electrode (4313) to protect it. In another embodiment, an additional base layer disposed on the lower side of the substrate layer may be further included. According to one embodiment, the substrate layer (431a) and / or the base layer may include a transparent insulating substrate. For example, the substrate layer (431a) and / or the base layer may be composed of a glass substrate, a quartz substrate, or a transparent resin substrate. In this case, the transparent resin substrate may include a polyimide-based resin, an acryl-based resin, a polyacrylate-based resin, a polycarbonate-based resin, a polyether-based resin, a sulfonic acid-based resin, or a polyethyleneterephthalate-based resin.

[0066] According to various embodiments, the display panel (431) may include a plurality of pixels (P) that are repositioned to have a lower placement density than the surrounding active area in an intermediate layer (431b) between the substrate layer (431a) and the protective layer (431c) of the transparent area (A1). In this case, the intermediate layer (431b) may remain in the transparent area (A1) or be omitted. According to one embodiment, the display panel (431) may include an opaque layer (460) disposed below (e.g., on the back side) of the display panel (431) in the transparent area (A1). According to one embodiment, the opaque layer (460) may include a colored (e.g., black) metal layer. In another embodiment, at least a portion of the opaque layer (460) may be disposed in the boundary area between the transparent area (A1) and the surrounding active area (A2). According to one embodiment, the metal layer may be formed on the back side of the display panel (431) through a deposition process. According to one embodiment, the opaque layer (460) may include a plurality of openings (461), and the transmittance of the transparent area (A1) may be determined by controlling the shape, size, arrangement density, and / or arrangement spacing of the plurality of openings (461). According to one embodiment, the plurality of openings (461) may be formed to have shapes, sizes, arrangement structures, and / or arrangement spacings that are identical or different from each other. According to one embodiment, a plurality of pixels (P) and / or a plurality of wires (dP e.g., wires (B) in FIG. 7a) may be arranged so as to overlap with an area (e.g., non-transparent area) where the plurality of openings (461) are avoided when viewed from above on the display panel (431). In another embodiment, a plurality of pixels (P) and / or a plurality of wires (e.g., wires (B) in FIG. 7a) may be arranged so as to overlap at least partially with the plurality of openings (461) when viewed from above on the display panel (431).

[0067] According to various embodiments, the display panel (431) may be formed to have a transmittance corresponding to a pixel placement density in the range of about 100 ppi (pixels per inch) to 300 ppi through a plurality of openings (461) in the transmission area (A1). According to one embodiment, the display panel (431) may be formed to have a transmittance in the transmission area (A1) through a plurality of openings (461) that exceeds the transmittance of the surrounding active area and is less than or equal to a transmittance corresponding to a pixel placement density in which one pixel (P) is placed in an area where 16 pixels (P) are to be placed. According to one embodiment, the display panel (431) may be formed to have a transmittance corresponding to a pixel placement density in which one pixel (P) is placed in an area where 4 pixels (P) are to be placed through a plurality of openings (461) in the transmission area (A1). According to one embodiment, the display panel (431) may be formed such that the ratio (transparent portion / non-transparent portion) of the transparent portion formed through the opening (461) in the transparent area (A1) and the non-transparent portion formed by the opaque layer includes a range of about 1 to 500.

[0069] FIGS. 7a to 9b are drawings illustrating the shape of an opening and the modulation transfer function (MTF) graph according to various embodiments of the present invention.

[0070] The openings (461, 811, 911) of FIGS. 7a through 9a are at least partially similar to the openings of FIG. 6, or may include other embodiments of the openings.

[0071] Referring to FIGS. 7a and 7b, the opaque layer (460) may include a plurality of openings (461) arranged at regular intervals. According to one embodiment, a display panel (e.g., the display panel (431) of FIG. 6) may include a plurality of pixels (P) arranged at a position overlapping with a non-transparent portion where the plurality of openings (461) are avoided, and a plurality of wirings (B) electrically connecting the plurality of pixels (P). In another embodiment, the plurality of pixels (P) and the plurality of wirings (B) may be arranged to overlap at least partially with the plurality of openings (461). According to one embodiment, the plurality of openings (461) may be formed to have at least partially straight sides. In this case, the plurality of openings (461) may be formed in a shape having at least one interior angle through at least one side. According to one embodiment, at least one of the interior angles may be formed to be 90 degrees or more.

[0072] According to various embodiments, the size (e.g., area) of each of the plurality of openings (461) may be determined to have a range of about 1 / 10 to 1 / 2 of the size of a unit pixel (P). According to one embodiment, the spacing (d) between adjacent openings (461) among the plurality of openings (461) may be determined to have a range of about 1 / 10 to 1 / 2 of the size of a unit pixel (P).

[0073] According to various embodiments, a plurality of openings (461) may each be formed in the shape of a regular octagon. According to one embodiment, a plurality of openings (461) having a regular octagonal shape may be formed in a size that satisfies the aforementioned transmittance. In this case, as shown in FIG. 7b, a camera device (e.g., camera device (500) of FIG. 5a) can obtain an MTF curve that matches the limit diffraction curve of the lens of the camera device through a transmission region having transmittance by the plurality of openings (461), which may mean that camera performance with a contrast of about 0.3 or higher in the low frequency band is achieved (region 701).

[0075] Referring to FIGS. 8a and 8b, the opaque layer (810) may include a plurality of openings (811) arranged at regular intervals. According to one embodiment, the plurality of openings (811) may be formed in a square shape arranged at regular intervals. According to one embodiment, through the plurality of openings (811) formed in a square shape, a higher transmittance may be exhibited in the transmission region than in the case of FIG. 7a. In this case, as shown in FIG. 8b, a camera device (e.g., the camera device (500) of FIG. 5a) can obtain an MTF curve that matches the limit diffraction curve of the camera device's lens through the transmission region having transmittance due to the plurality of openings (811). This may mean that an image with better resolution can be obtained through a curve that is more linearly exhibited in the low-frequency band than in the case of FIG. 7b.

[0077] Referring to FIGS. 9a and 9b, the opaque layer (910) may include a plurality of openings (911) arranged at regular intervals. According to one embodiment, the plurality of openings (911) may be formed in a regular pentagonal shape arranged at regular intervals. In this case, as shown in FIG. 9b, a camera device (e.g., the camera device (500) of FIG. 5a) can obtain an MTF curve that generally matches the limit diffraction curve of the lens of the camera device through a transmission region having transmittance through the plurality of openings (911), which may mean that camera performance is exhibited in the low frequency band.

[0079] According to various embodiments, high diffraction may occur in the transmission area of ​​a display panel through the shape of a plurality of openings. For example, the width of the openings along the x-axis and / or y-axis may affect the diffraction angle, thereby serving to collect or disperse the diffracted energy. For example, the spacing between the openings may cause destructive interference between the diffracted light sources to generate a second peak, thereby narrowing or widening the spacing of the diffraction pattern. For example, the shape of the openings may change the diffraction angle, thereby affecting the shape of the diffraction pattern. When the diffracted light passes through the lens of a camera device and reaches the image sensor, it may degrade the image quality as stray light. Depending on the shape of the openings, when the diffracted light is concentrated, it may form a shape such as a cross, a double image may appear where the image appears in two or three layers around the image shape, or a phenomenon in which the image appears blurry may occur.

[0080] According to an exemplary embodiment of the present invention, by appropriately adjusting the shape, size, arrangement structure, and / or arrangement spacing of a plurality of openings, a transmission area of ​​a display capable of reducing the degree of diffraction while maintaining the MTF performance of a camera device can be provided.

[0082] FIGS. 10a to 12b are drawings showing simulation images of the shape of the opening due to the difference in transmission density and the corresponding degree of light diffraction according to various embodiments of the present invention.

[0083] Referring to FIG. 10a, the opaque layer (1010) may include a plurality of openings (1011) arranged at regular intervals. According to one embodiment, the plurality of openings (1011) may be formed in a hexagonal shape arranged at regular intervals.

[0084] Referring to FIG. 11a, the opaque layer (1110) may include a plurality of continuously formed hexagonal openings (1111). According to one embodiment, the arrangement density of the plurality of openings (1111) may be higher than the arrangement density of the plurality of openings in FIG. 10.

[0085] Referring to FIGS. 10b and FIGS. 11b, it can be seen that the degree of light diffraction is smaller in a transmission area (e.g., transmission area (A1) of FIG. 6) containing a plurality of openings (1111) of FIG. 11a having a relatively high arrangement density than in a transmission area (e.g., transmission area (A1) of FIG. 6) containing a plurality of openings (1011) of FIG. 10a having a low arrangement density, which may mean that the quality of the image captured by the camera device (e.g., camera device (500) of FIG. 5a) is better in the case of FIG. 11a.

[0086] Referring to FIG. 12a, the opaque layer (1210) may include a plurality of openings (1211) arranged at regular intervals. According to one embodiment, the plurality of openings (1211) may be arranged at regular intervals and formed in a pentagonal shape having a lower arrangement density than in FIG. 10a.

[0087] In this case, as shown in FIG. 12b, it can be seen that the degree of light diffraction is greater than in the case of FIG. 11b, which may mean that the quality of the image captured by the camera device (e.g., the camera device (500) of FIG. 5a) is less superior than in the case of FIG. 11a.

[0089] FIGS. 13a to 14b are drawings showing simulation images of openings having different shapes and the same area according to various embodiments of the present invention and the corresponding degree of light diffraction.

[0090] Referring to FIG. 13a, the opaque layer (1310) may include a plurality of openings (1311) arranged at regular intervals. According to one embodiment, the plurality of openings (1311) may be formed in a regular shape arranged at regular intervals.

[0091] Referring to FIG. 14a, the opaque layer (1410) may include a plurality of hexagonal openings (1411) formed at regular intervals. According to one embodiment, the size of each of the plurality of openings (1411) may be the same as each of the plurality of openings (1311) of FIG. 13a, differing only in shape.

[0092] Referring to FIGS. 13b and FIGS. 14b, it can be seen that even if a transmission region (e.g., transmission region (A1) of FIG. 6) has the same size and only differs in shape, the degree of diffraction varies depending on the shape of the opening. For example, it can be seen that a transmission region (e.g., transmission region (A1) of FIG. 6) containing a plurality of openings (1411) of FIG. 14a, which has a shape favorable for scattering light, has a smaller degree of light diffraction than a transmission region (e.g., transmission region (A1) of FIG. 6) containing a plurality of openings (1311) of FIG. 13a, which has a shape favorable for scattering light, and this may mean that the quality of the image captured by the camera device (e.g., camera device (500) of FIG. 5a) is superior in the case of FIG. 14a.

[0094] FIGS. 15a to 20c are drawings showing MTF graphs and corresponding simulation images of the degree of light rotation according to the presence or absence of a protrusion of the opening according to various embodiments of the present invention.

[0095] According to various embodiments, a plurality of openings disposed in a transmission region must be formed in various shapes having straight sides to prevent degradation of MTF performance; however, a problem may arise in which the degree of light diffraction increases due to the presence of specific patterns on these straight sides. According to an exemplary embodiment of the present invention, various shapes of a plurality of openings can be presented to reduce the degree of light diffraction while maintaining MTF performance.

[0096] Referring to FIG. 15a, the opaque layer (1510) may include a plurality of openings (1511) arranged at regular intervals. According to one embodiment, the plurality of openings (1511) may be formed in a cross shape arranged at regular intervals. According to one embodiment, the plurality of openings (1511) may be formed in a cross shape through straight sides (1511a).

[0097] Referring to FIG. 16a, the opaque layer (1610) may include a plurality of openings (1611) arranged at regular intervals. According to one embodiment, the plurality of openings (1611) may be based on the plurality of openings (1511) of FIG. 15a, where a straight side (1511a) is replaced by a plurality of protrusions (1611a). According to one embodiment, the plurality of protrusions (1611a) may include a continuous plurality of protrusions (1611a) protruding outward from a virtual straight line (L) formed at least partially of the plurality of openings (1611). According to one embodiment, the plurality of protrusions (1611a) may be formed to have the same or different radii of curvature. According to one embodiment, each of the plurality of protrusions (1611a) may be formed to have a radius of curvature of at least 1 / 40 of the length of one side.

[0098] Referring to FIGS. 15b and FIGS. 16b, it can be seen that the degree of diffraction in a transmission region (e.g., transmission region (A1) of FIG. 6) varies depending on the presence or absence of a plurality of protrusions (1611a). For example, it can be seen that the degree of diffraction of light is smaller in a transmission region (e.g., transmission region (A1) of FIG. 6) that includes a plurality of openings (1611) of FIG. 16a, which has a shape favorable for scattering light by including a plurality of protrusions (1611a), than in a transmission region (e.g., transmission region (A1) of FIG. 6) that includes a plurality of openings (1511) of FIG. 15a, which has a shape favorable for scattering light by having a straight side (1511a), and this may mean that the quality of the image captured by the camera device (e.g., camera device (500) of FIG. 5a) is superior in the case of FIG. 16a.

[0099] In this case, referring to FIG. 15c and FIG. 16c, it can be seen that the MTF performance of the transmission area through the two openings (1511, 1611) remains unchanged regardless of the presence or absence of the plurality of protrusions (1611a).

[0101] Referring to FIG. 17a, the opaque layer (1710) may include a plurality of openings (1711) arranged at regular intervals. According to one embodiment, the plurality of openings (1711) may be based on the plurality of openings (1511) of FIG. 15a, where a straight side (1511a) is replaced by a plurality of protrusions (1711a). According to one embodiment, the plurality of protrusions (1711a) may be formed as a polygon (e.g., a triangle) consisting of two straight-shaped small sides. In this case, each small side may have a length of at least 1 / 20 of the length of one side of the plurality of openings (1711), and the interior angle of the plurality of protrusions (1711a) may be formed to be at least 10 degrees. In another embodiment, the plurality of protrusions (1711a) may be formed as polygonal shapes such as squares or pentagons, rather than triangles.

[0102] Referring to FIGS. 15b and FIGS. 17b, it can be seen that the degree of diffraction in a transmission region (e.g., transmission region (A1) of FIG. 6) varies depending on the presence or absence of a plurality of protrusions (1711a). For example, it can be seen that the degree of diffraction of light is smaller in a transmission region (e.g., transmission region (A1) of FIG. 6) that includes a plurality of openings (1711) of FIG. 17a, which has a shape favorable for scattering light by including a plurality of protrusions (1711a), than in a transmission region (e.g., transmission region (A1) of FIG. 6) that includes a plurality of openings (1511) of FIG. 15a, which has a shape favorable for scattering light by having a straight side (1511a), and this may mean that the quality of the image captured by the camera device (e.g., camera device (500) of FIG. 5a) is superior in the case of FIG. 16a.

[0103] In this case, referring to FIG. 15c and FIG. 17c, it can be seen that the MTF performance of the transmission area through the two openings (1511, 1711) remains unchanged regardless of the presence or absence of the plurality of protrusions (1711a).

[0105] Referring to FIG. 18a, the opaque layer (1810) may include a plurality of openings (1811) arranged at regular intervals. According to one embodiment, the plurality of openings (1811) may include a plurality of protrusions (1811a) having a curved shape based on the plurality of openings (1611) of FIG. 16a, and a straight side (1811b) connecting at least partially the plurality of protrusions (1811a). According to one embodiment, substantially most of the side of the plurality of openings (1811) may be formed with a plurality of protrusions (1811a) having a curved shape, and only a portion of the area may be formed to have a straight side (1811b). According to one embodiment, this partial straight side (1811b) may help prevent MTF performance degradation.

[0106] Referring to FIG. 15b and FIG. 18b, it can be seen that the degree of diffraction in the transmission region (e.g., transmission region (A1) of FIG. 6) varies depending on the presence or absence of a plurality of protrusions (1811a). For example, it can be seen that a transmission area (e.g., transmission area (A1) of FIG. 6) comprising a plurality of openings (1811) of FIG. 18a, which has a shape favorable for scattering light by including a plurality of protrusions (1811a) and a relatively small straight side (1811b), has a smaller degree of light diffraction than a transmission area (e.g., transmission area (A1) of FIG. 6) comprising a plurality of openings (1511) of FIG. 15a, which has a shape favorable for scattering light by having a straight side (1511a), and this may mean that the quality of the image captured by the camera device (e.g., camera device (500) of FIG. 5a) is better in the case of FIG. 16a.

[0107] In this case, referring to FIG. 15c and FIG. 18c, it can be seen that the MTF performance of the transmission area through the two openings (1511, 1811) remains unchanged regardless of the presence or absence of the plurality of protrusions (1711a).

[0108] Referring to FIG. 18d, the opaque layer (1812) may include a plurality of openings (1812) arranged at regular intervals. According to one embodiment, the plurality of openings (1812) may include a plurality of protrusions (1812a) having a curved shape based on the plurality of openings (1811) of FIG. 18a, and at least one curved side (1812b) having a radius of curvature different from that of the plurality of protrusions (1812a). According to one embodiment, the plurality of openings (1812) may be formed such that substantially most of the side is formed by a plurality of protrusions (1812a) having a curved shape, thereby exhibiting performance similar to the plurality of openings (1811) of FIG. 18a.

[0110] Referring to FIG. 19a, the opaque layer (1910) may include a plurality of openings (1911) arranged at regular intervals. According to one embodiment, the plurality of openings (1911) may be formed to have a straight edge surface (1911a) with four corners cut diagonally based on a plurality of openings (1311) having a square shape of FIG. 13a.

[0111] Referring to FIG. 20a, the opaque layer (2010) may include a plurality of openings (2011) arranged at regular intervals. According to one embodiment, the plurality of openings (2011) may be based on the plurality of openings (1911) of FIG. 19a, and all straight sides including the edge surface (1911a) may be replaced with a plurality of protrusions (2011a).

[0112] Referring to FIGS. 19b and FIGS. 20b, it can be seen that the degree of diffraction in a transmission region (e.g., transmission region (A1) of FIG. 6) varies depending on the presence or absence of a plurality of protrusions (2011a). For example, it can be seen that a transmission region (e.g., transmission region (A1) of FIG. 6) containing a plurality of openings (2011) of FIG. 20a, which has a shape favorable for scattering light by including a plurality of protrusions (2011a), has a smaller degree of light diffraction than a transmission region (e.g., transmission region (A1) of FIG. 6) containing a plurality of openings (1911) of FIG. 19a, which has an edge surface (1911a) and a shape relatively unfavorable for scattering light, and this may mean that the quality of the image captured by a camera device (e.g., camera device (500) of FIG. 5a) is superior in the case of FIG. 20a.

[0113] In this case, referring to FIG. 19c and FIG. 20c, it can be seen that the MTF performance of the transmission area through the two openings (1911, 2011) remains unchanged regardless of the presence or absence of the plurality of protrusions (1611a).

[0114] According to various embodiments, by appropriately adjusting the shape, size, placement density, and / or placement spacing of a plurality of openings (e.g., a plurality of openings (461) of FIG. 6) of an opaque layer (e.g., an opaque layer (460) of FIG. 6) disposed on a display panel (e.g., a display panel (431) of FIG. 6), a camera device (e.g., a camera device (500) of FIG. 5a) can provide an improved image by reducing the degree of diffraction of light entering from a transmission area (e.g., a transmission area (A1) of FIG. 6) while maintaining high MTF characteristics in a transmission area (e.g., a transmission area (A1) of FIG. 6).
