[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0009] 1. First embodiment 1 is a cross-sectional view schematically illustrating a camera-integrated display according to a first embodiment, and also includes arrows indicating the front and rear of the camera-integrated display.

[0010] The camera-integrated display 1 of the first embodiment shown in Fig. 1 displays an image facing forward and captures an image of the front side. The camera-integrated display 1 is incorporated into an in-vehicle device and housed in a housing 71 of the in-vehicle device. The camera-integrated display 1 may also be incorporated into a device other than an in-vehicle device.

[0011] As shown in FIG. 1, the camera-embedded display 1 comprises a transparent cover 11, a transparent window 12, a first light-shielding film 13, an optically clear adhesive (OCA) layer 14, a display panel 15, a camera 16, a second light-shielding film 17, a backlight 18, and a light-shielding body 19.

[0012] The transparent cover 11 has a plate-like shape. Therefore, the transparent cover 11 has a front surface 11a and a rear surface 11b. The front surface 11a and the rear surface 11b are on opposite sides, i.e., the front side and the rear side, respectively. The rear surface 11b is on the side where the display panel 15 is disposed. The transparent cover 11 transmits the image light L2 incident on the rear surface 11b and emits the transmitted image light L2 from the front surface 11a.

[0013] A first hole 11h is formed in the transparent cover 11. Therefore, the transparent cover 11 has a first inner surface 11c that faces the first hole 11h and defines the first hole 11h. The first hole 11h has a circular planar shape. The first hole 11h may have a planar shape other than a circular planar shape.

[0014] The transparent cover 11 is made of a transparent material. The transparent material is glass, and the transparent cover 11 is a glass cover. The transparent material may be a material other than glass, and the transparent cover 11 may be a cover other than a glass cover. For example, the transparent material may be plastic, and the transparent cover 11 may be a plastic cover.

[0015] The transparent window 12 has a plate-like shape. Therefore, the transparent window 12 has an incident surface 12a, an exit surface 12b, and a first side surface 12c. The incident surface 12a and the exit surface 12b are located on opposite sides, at the front and rear, respectively. The incident surface 12a is located at the same front-rear position as the front surface 11a of the transparent cover 11. The exit surface 12b is located on the side where the camera 16 is disposed. The transparent window 12 transmits subject light L3 incident on the incident surface 12a and emits the transmitted subject light L3 from the exit surface 12b.

[0016] The transparent window 12 has a circular planar shape. The transparent window 12 may have a planar shape other than a circular planar shape. The transparent window 12 has a planar shape that is slightly smaller than the planar shape of the first hole 11h. The transparent window 12 is inserted into the first hole 11h. The first side surface 12c of the transparent window 12 faces the first inner surface 11c of the transparent cover 11 and is slightly spaced from the first inner surface 11c radially inward of the first hole 11h and the transparent window 12.

[0017] The transparent window 12 is made of a transparent material. The transparent material is glass, and the transparent window 12 is a glass window. The transparent material may be a material other than glass, and the transparent window 12 may be a window other than a glass window. For example, the transparent material may be plastic, and the transparent window 12 may be a plastic window.

[0018] The transparent window 12 has a thickness greater than that of the transparent cover 11. Therefore, as shown in FIG. 1 , the transparent window 12 has an in-hole portion 21 and an out-hole portion 22. The in-hole portion 21 is disposed within the first hole 11h. The out-hole portion 22 is disposed outside the first hole 11h and is disposed on the rear side of the first hole 11h. The in-hole portion 21 has an incident surface 12a of the transparent window 12. The out-hole portion 22 has an exit surface 12b of the transparent window 12. Therefore, the exit surface 12b of the transparent window 12 is located rearward of the rear surface 11b of the transparent cover 11.

[0019] The first light-shielding film 13 is disposed on the first side surface 12c of the transparent window 12. The first light-shielding film 13 has a first end surface 13a and a first outer peripheral surface 13b. The first end surface 13a is located on the rear side. The first outer peripheral surface 13b is located radially outward. The first outer peripheral surface 13b faces the first inner surface 11c of the transparent cover 11 and is in close contact with the first inner surface 11c. The first light-shielding film 13 blocks glare light L4 and other light incident on the first outer peripheral surface 13b, thereby preventing the glare light L4 and other light from entering the transparent window 12. This allows the first light-shielding film 13 to prevent the glare light L4 and other light from reaching the camera 16 via the transparent cover 11 and the transparent window 12. The glare light L4 is generated by external light and causes glare.

[0020] A light-shielding object made of a tube, a wall, or the like has a large thickness and is self-supporting. Therefore, the light-shielding object made of a tube, a wall, or the like maintains its shape without being supported by other elements. If a light-shielding object made of a tube, a wall, or the like were provided instead of the first light-shielding film 13, the distance from the first side surface 12c of the transparent window 12 to the first inner surface 11c of the transparent cover 11 would be longer, and the area in which the image is displayed would be narrower. In contrast, the first light-shielding film 13 has only a small thickness and is not self-supporting. Therefore, the first light-shielding film 13 maintains its shape by being supported by the first side surface 12c. If the first light-shielding film 13 were provided instead, the distance from the first side surface 12c to the first inner surface 11c would be shorter, and the area in which the image is displayed would be wider.

[0021] The first light-shielding film 13 is made of, for example, a metal. The metal is, for example, tungsten or molybdenum. The first light-shielding film 13 has a thickness of, for example, several hundred nm or about 1 μm to several μm. The first light-shielding film 13 is formed by, for example, a physical vapor deposition (PVD) method.

[0022] The OCA layer 14 is disposed between the transparent cover 11 and the display panel 15. The OCA layer 14 bonds the transparent cover 11 to the display panel 15. The OCA layer 14 is made of a transparent material.

[0023] The display panel 15 has a plate-like shape. Therefore, the display panel 15 has a first main surface 15a and a second main surface 15b. The first main surface 15a and the second main surface 15b are located on opposite sides, i.e., the front side and the rear side, respectively. The first main surface 15a is located on the side where the transparent cover 11 and the OCA layer 14 are disposed. The second main surface 15b is located on the side where the backlight 18 is disposed. The display panel 15 modulates backlight light L1 incident on the second main surface 15b to generate image light L2, and emits the generated image light L2 from the first main surface 15a. The first main surface 15a is covered with the transparent cover 11.

[0024] A second hole 15h is formed in the display panel 15. Therefore, the display panel 15 has a second inner surface 15c that faces the second hole 15h and defines the second hole 15h. The second hole 15h has a circular planar shape. The second hole 15h may have a planar shape other than a circular planar shape.

[0025] The display panel 15 is a liquid crystal display (LCD) panel. Therefore, as shown in FIG. 1, the display panel 15 includes a first polarizing plate 31, a first substrate 32, a liquid crystal layer 33, a second substrate 34, and a second polarizing plate 35. The first polarizing plate 31, the first substrate 32, the liquid crystal layer 33, the second substrate 34, and the second polarizing plate 35 are stacked in the front-to-back direction. Therefore, the display panel 15 has many interfaces that cause stray light L5. The display panel 15 may be a display panel other than an LCD panel.

[0026] The camera 16 has a cylindrical shape. Therefore, the camera 16 has an incident surface 16a and a second side surface 16b. The camera 16 may have a shape other than a cylindrical shape. The incident surface 16a is on the side where the transparent window 12 is disposed. The camera 16 forms a subject image by focusing the subject light L3 incident on the incident surface 16a, and outputs an image signal corresponding to the formed subject image. The incident surface 16a faces the exit surface 12b of the transparent window 12 and is in close contact with the exit surface 12b. As a result, the camera 16 captures an image of the front side through the transparent window 12.

[0027] The camera 16 is not inserted into the first hole 11h but is located behind the first hole 11h. The camera 16 has a planar shape that is slightly smaller than the planar shape of the second hole 15h. The camera 16 is inserted into the second hole 15h. The second side surface 16b of the camera 16 faces the second inner surface 15c of the display panel 15 and is slightly spaced from the second inner surface 15c radially inward of the camera 16 and the second hole 15h of the display panel 15.

[0028] The camera 16 includes a lens, a lens barrel, an imaging element, an imaging element board, etc. (not shown). The lens, lens barrel, imaging element, imaging element board, etc. are integrated together to form a camera module.

[0029] The second light-shielding film 17 is disposed on the second side surface 16 b of the camera 16 .

[0030] The second light-shielding film 17 has a second end face 17a and a second outer peripheral face 17b. The second end face 17a is located on the front side. The second outer peripheral face 17b is located on the radially outer side. The second outer peripheral face 17b faces the second inner surface 15c of the display panel 15. The second light-shielding film 17 blocks stray light L5 and the like that is incident on the second outer peripheral face 17b, thereby preventing the stray light L5 and the like from reaching the camera 16. This allows the second light-shielding film 17 to prevent the stray light L5 and the like from reaching the camera 16.

[0031] A light-shielding object made of a tube, a wall, or the like has a large thickness and is self-supporting. Therefore, the light-shielding object made of a tube, a wall, or the like maintains its shape without being supported by other elements. If a light-shielding object made of a tube, a wall, or the like were provided instead of the second light-shielding film 17, the distance from the second side surface 16b of the camera 16 to the second inner surface 15c of the display panel 15 would be longer, and the area in which an image is displayed would be narrower. In contrast, the second light-shielding film 17 has only a small thickness and is not self-supporting. Therefore, the second light-shielding film 17 maintains its shape by being supported by the second side surface 16b. If the second light-shielding film 17 were provided instead, the distance from the second side surface 16b to the second inner surface 15c would be shorter, and the area in which an image is displayed would be wider.

[0032] The second light-shielding film 17 is made of, for example, a metal. The metal is, for example, tungsten or molybdenum. The second light-shielding film 17 has a thickness of, for example, several hundred nanometers or about 1 μm to several μm. The second light-shielding film 17 is formed by, for example, a PVD method.

[0033] The camera 16 has the same planar shape as the transparent window 12. Therefore, the second end surface 17a of the second light-shielding film 17 faces the first end surface 13a of the first light-shielding film 13. The first light-shielding film 13 reaches the rear end of the first side surface 12c of the transparent window 12, and the second light-shielding film 17 reaches the front end of the second side surface 16b of the camera 16, so that the incident surface 16a of the camera 16 is in close contact with the exit surface 12b of the transparent window 12. As a result, the second end surface 17a is in close contact with the first end surface 13a. The second end surface 17a may be slightly spaced from the first end surface 13a.

[0034] The backlight 18 faces the second main surface 15b of the display panel 15. The backlight 18 emits backlight light L1 toward the front. As a result, the backlight 18 irradiates the second main surface 15b with the backlight light L1. As a result, the backlight light L1 is incident on the second main surface 15b. The backlight 18 is an LED light source equipped with light-emitting diodes (LEDs). The backlight 18 may be a light source other than an LED light source.

[0035] A third hole 18h is formed in the backlight 18. The camera 16 is inserted into the third hole 18h.

[0036] The light shielding body 19 is disposed across the first outer peripheral surface 13b of the first light shielding film 13 and the second outer peripheral surface 17b of the second light shielding film 17. The light shielding body 19 is disposed continuously around the entire circumference on the first outer peripheral surface 13b and the second outer peripheral surface 17b. This prevents glare light L4, stray light L5, and the like from entering between the first end surface 13a and the second end surface 17a even when the first end surface 13a and the second end surface 17a are slightly spaced apart from each other. The light shielding body 19 is disposed outside the first hole 11h of the transparent cover 11 and behind the first hole 11h. The light shielding body 19 is made of, for example, a light-shielding resin.

[0037] 2. Second embodiment The following describes the differences between the second embodiment and the first embodiment. For points that are not described, the second embodiment also employs the same configuration as that employed in the first embodiment.

[0038] 2 is a cross-sectional view schematically illustrating a camera-integrated display according to a second embodiment, and also includes arrows indicating the front and rear of the camera-integrated display.

[0039] In the camera-integrated display 2 of the second embodiment shown in Fig. 2, the incident surface 16a of the camera 16 is spaced rearward from the exit surface 12b of the transparent window 12. Therefore, the second end surface 17a of the second light-shielding film 17 is spaced rearward from the first end surface 13a of the first light-shielding film 13. In addition, the light-shielding body 19 includes a first portion 41 disposed between the first end surface 13a and the second end surface 17a, and a second portion 42 disposed across the first outer peripheral surface 13b of the first light-shielding film 13 and the second outer peripheral surface 17b of the second light-shielding film 17. The first light-shielding film 13 and the second light-shielding film 17 are in close contact with the light-shielding body 19 and are in contact with each other via the light-shielding body 19.

[0040] In the camera-integrated display 2, as in the camera-integrated display 1, the area in which an image is displayed is widened, and it is possible to prevent glare light L4, stray light L5, etc. from reaching the camera 16.

[0041] 3 Third embodiment The following describes the differences between the third embodiment and the first embodiment. For points that are not described, the third embodiment also employs the same configuration as that employed in the first embodiment.

[0042] FIG. 3 is a cross-sectional view schematically illustrating a camera-integrated display according to the third embodiment.

[0043] The camera-integrated display 3 of the third embodiment shown in FIG.

[0044] In the camera-integrated display 3, the transparent window 12 has a thickness thinner than that of the transparent cover 11, and includes the in-hole portion 21 but no out-hole portion 22. Therefore, the in-hole portion 21 defines the exit surface 12b of the transparent window 12. Therefore, the exit surface 12b is located forward of the rear surface 11b of the transparent cover 11.

[0045] In addition, in the camera-integrated display 3, the front end of the camera 16 is inserted into the first hole 11h. The incident surface 16a of the camera 16 is in close contact with the exit surface 12b of the transparent window 12. The second end surface 17a of the second light-shielding film 17 is in close contact with the first end surface 13a of the first light-shielding film 13.

[0046] In the camera-integrated display 3, as in the camera-integrated display 1, the area in which an image is displayed is widened, and it is possible to prevent glare light L4, stray light L5, etc. from reaching the camera 16.

[0047] 4 Fourth embodiment The following describes the differences between the fourth embodiment and the first embodiment. For points that are not described, the fourth embodiment also employs the same configuration as that employed in the first embodiment.

[0048] FIG. 4 is a cross-sectional view schematically illustrating a camera-integrated display according to the fourth embodiment.

[0049] In the camera-integrated display 4 of the fourth embodiment shown in Fig. 4, the transparent window 12 has the same thickness as the transparent cover 11, and includes the in-hole portion 21 but not the out-hole portion 22. Therefore, the in-hole portion 21 defines the light exit surface 12b of the transparent window 12. Therefore, the light exit surface 12b is located at the same position in the front-rear direction as the rear surface 11b of the transparent cover 11. The first light-shielding film 13 may be located on the first inner surface 11c of the transparent cover 11 and supported by the first inner surface 11c, or may be located on the first side surface 12c of the transparent window 12 and supported by the first side surface 12c.

[0050] In the camera-integrated display 4, the incident surface 16a of the camera 16 is spaced rearward from the exit surface 12b of the transparent window 12. The second end surface 17a of the second light-shielding film 17 is spaced rearward from the first end surface 13a of the first light-shielding film 13.

[0051] In the camera-integrated display 4, the light blocking body 19 includes a portion 51 disposed between the first end face 13a and the second end face 17a.

[0052] In the camera-integrated display 4, as in the camera-integrated display 1, the area in which an image is displayed is widened, and it is possible to prevent glare light L4, stray light L5, etc. from reaching the camera 16.

[0054] FIG. 5 is a cross-sectional view schematically illustrating a camera-integrated display according to the fifth embodiment.

[0055] In the fifth embodiment of the camera-integrated display 5 shown in Figure 5, the light-shielding body 19 has a first portion 61 arranged between the first end face 13a of the first light-shielding film 13 and the second end face 17a of the second light-shielding film 17, and a second portion 62 arranged on the second outer peripheral surface 17b of the second light-shielding film 17.

[0056] In the camera-integrated display 5, as in the camera-integrated display 1, the area in which an image is displayed is widened, and it is possible to prevent glare light L4, stray light L5, etc. from reaching the camera 16.

[0057] The present disclosure is not limited to the above-described embodiments, and may be replaced with a configuration that is substantially the same as the configuration shown in the above-described embodiments, a configuration that has the same effect, or a configuration that can achieve the same purpose.
