Referring to fig. 1 and 2, fig. 1 is a partial schematic structural diagram of a conventional display device, and fig. 2 is a schematic structural diagram of a sensor in the display device provided in fig. 1 being tilted.
The display device in fig. 1 includes a cover plate 10, foam 11, an adhesive tape 12, a flexible circuit board 13, and a light sensor 14. The foam 11 is disposed on the surface of the cover plate 10, and the foam 11 has a first through hole 111. The adhesive tape 12 is disposed on the surface of the foam 11 away from the cover plate 10, and the adhesive tape 12 has a second through hole 121. The first through hole 111 communicates with the second through hole 121 and forms a light transmission hole 110. The flexible circuit board 13 is arranged on the surface of the adhesive tape 12 far away from the foam 11. The light sensor 14 is disposed on one side of the flexible circuit board 13 close to the cover plate 10 and located in the light hole 110. The surface of the foam 11 close to the adhesive tape 12 is a plane, and the surface of the adhesive tape 12 close to the foam 11 is a plane, that is, the foam 11 and the adhesive tape 12 are both flat structures, and the ideal state after assembly is shown in fig. 1; due to the insufficient contact area between the foam 11 and the adhesive tape 12, the phenomenon that the light sensor 14 is inclined during the assembly process is easy to occur, as shown in fig. 2. When the light sensor 14 is inclined, ambient light may enter from the gap between the foam 11 and the adhesive tape 12 and be recognized by the light sensor 14, so that the light sensing function is affected; since the light sensor 14 is fragile, the light sensor 14 is inclined seriously, and the light sensor 14 is crushed.
Referring to fig. 3, fig. 3 is a schematic partial structure diagram of a display device according to a first embodiment of the present disclosure.
The display device comprises a cover plate 1, a shading layer 2, a supporting layer 3, a flexible circuit board 4 and a light sensor 5. The light shielding layer 2 is disposed on one side of the cover plate 1, and the light shielding layer 2 has a first through hole 21. The support layer 3 is disposed on a side of the light shielding layer 2 away from the cover plate 1, and the support layer 3 has a second through hole 31. The first through hole 21 communicates with the second through hole 31 and forms a light transmission hole 200. The flexible wiring board 4 is disposed on a side of the support layer 3 away from the light-shielding layer 2. The light sensor 5 is disposed on one side of the flexible circuit board 4 close to the cover plate 1 and located in the light hole 200. Wherein the shading layer 2 is provided with a first opening 20, and/or the supporting layer 3 is provided with a second opening 30, part of the shading layer 2 is positioned in the second opening 30, and/or at least part of the supporting layer 3 is positioned in the first opening 20, so that the distance between the flexible circuit board 4 and the cover plate 1 is smaller than the sum of the thickness of the shading layer 2 and the thickness of the supporting layer 3. The display device provided by the present application further includes a screen body (not shown) connected to the flexible printed circuit 4, and a control panel (not shown). The cover plate 1 covers the screen body and is positioned on the light emergent side of the screen body. The control panel is provided with a time sequence control chip, a power supply, a driving chip, a connector and other devices, and the control panel is electrically connected with the screen body. One end of the flexible printed circuit 4 is connected to the control panel, and the other end of the flexible printed circuit 152 is disposed between the cover 12 and the display 13.
Specifically, the light shielding layer 2 is provided with a first opening 20, and the support layer 3 is partially disposed in the first opening 20; or, the support layer 3 is provided with a second opening 30, and the light shielding layer 2 is at least partially arranged in the second opening 30; alternatively, the light-shielding layer 2 is provided with the first opening 20, the support layer 3 is provided with the second opening 30, the light-shielding layer 2 is partially disposed in the second opening 30 of the support layer 3, and the support layer 3 is partially disposed in the first opening 20 of the light-shielding layer 2. By the arrangement mode, the distance between the flexible circuit board 4 and the cover plate 1 is smaller than the sum of the thickness of the shading layer 2 and the thickness of the supporting layer 3. It is understood that the thickness of the light shield layer 2 refers to the thickness thereof where the first opening 20 is not provided, and the thickness of the support layer 3 refers to the thickness thereof where the second opening 30 is not provided.
By arranging the first through hole 21 on the light shielding layer 2 and the second through hole 31 on the supporting layer 3, the first through hole 21 and the second through hole 31 cooperate to form the light transmitting hole 200, and the light sensor 5 recognizes the light change of the ambient light incident through the cover plate 1 through the light transmitting hole 200, so as to adjust the display brightness of the display device. The aperture size of the first and second through holes 21 and 31 is determined by the light acceptance angle of the light sensor 5 and the associated assembly tolerance.
By providing the first opening 20 in the light shielding layer 2 and/or the second opening 30 in the support layer 3, the distance between the flexible wiring board 4 and the cover plate 1 can be made smaller than the sum of the thickness of the light shielding layer 2 and the thickness of the support layer 3. The smaller the distance between the flexible wiring board 4 and the cover plate 1, the smaller the distance between the cover plate 1 and the photosensor 5 disposed on the side of the flexible wiring board 4 close to the cover plate 1. It can be understood that when the structure and the size of the light sensor 5 are determined, the light receiving angle of the light sensor 5 is determined, and the light receiving area a of the light sensor 5 is tapered, and the width of the light receiving area a is wider along the incident direction of the ambient light of the light sensor 5 (the incident direction of the ambient light is perpendicular to the extending direction of the cover plate 1) and further away from the light sensor 5 (as shown in fig. 3); the distance between the light sensor 5 and the cover plate 1 is reduced, which is beneficial to reducing the aperture of the first through hole 21 and further beneficial to increasing the attaching area between the light shielding layer 2 and the supporting layer 3, thereby reducing the probability of the inclination of the light sensor 5 caused by the insufficient contact area between the light shielding layer 2 and the supporting layer 3 in the installation and use processes. That is, according to the light sensation FOV characteristic of the light sensor 5, the smaller the distance between the flexible wiring board 4 and the cover plate 1 is, the smaller the size of the aperture of the first through hole 21 on the light shielding layer 2 can be.
The first opening 20 is formed in the light shielding layer 2 and/or the second opening 30 is formed in the supporting layer 3, so that the attaching area and the bonding firmness between the light shielding layer 2 and the supporting layer 3 can be further increased, the light sensor 5 is prevented from inclining as much as possible, and the phenomenon that environmental light enters the light sensor 5 from other ways to affect the function of the light sensor and crush the light sensor due to the inclination of the light sensor.
The photo sensor 5 is fixed to the flexible wiring board 4 through the light shielding layer 2 and the support layer 3. The supporting layer 3 protects the light sensor 5 while fixing the light sensor 5, so that the light sensor 5 is prevented from being broken. The structures of the cover plate 1, the light-shielding layer 2, the support layer 3, the flexible wiring board 4, and the photo sensor 5 are not limited and can be selected as needed. Optionally, the light shielding layer 2 is made of foam, and the supporting layer 3 is an adhesive tape. The thickness of the light shading layer 2 is 0.1mm-0.3mm, the thickness of the supporting layer 3 is 0.5mm-1.0mm, and the thicknesses of the light shading layer 2 and the supporting layer 3 are specifically designed according to needs, which is not limited in the application.
Referring to fig. 3, in the first embodiment of the display device, the support layer 3 includes a ring-shaped body. The first openings 20 comprise annular grooves 22 provided in the surface of the opacifying layers 2 adjacent to the support layer 3. The supporting layer 3 is partially arranged in the annular groove 22; the portion of the support layer 3 not disposed in the annular groove 22 protects the optical sensor 5. That is, the support layer 3 is disposed in the annular groove 22, and the depth of the annular groove 22 is smaller than the thickness of the support layer 3. Specifically, the surface of the support layer 3 close to the light shield layer 2 is a plane, that is, the support layer 3 is a flat structure; the surface of the support layer 3 adjacent to the light-shielding layer 2 abuts against the bottom surface of the annular groove 22; along the thickness direction of the support layer 3, the support layer 3 is partially disposed in the annular groove 22. The annular width D1 of the support layer 3 may be set to match the width D2 of the annular groove 22, so that the support layer 3 can be fitted into the annular groove 22. In another embodiment, the width D2 of the annular groove 22 is greater than the annular width D1 of the support layer 3, and the side surface of the support layer 3 may be spaced from the side surface of the annular groove 22 in a state where the support layer 3 is assembled in the annular groove 22, and the spacing distance is set to facilitate the assembly of the support layer 3 in the annular groove 22, so as to reduce the difficulty of assembling the support layer 3 in the annular groove 22.
By arranging the support layer 3 in the annular grooves 22 on the light-shielding layers 2, the contact area between the support layer 3 and the light-shielding layers 2 is increased, and this arrangement can avoid the inclination of the photo sensors 5, and thus avoid the problem of breakage caused by the inclination of the photo sensors 5. And the supporting layer 3 is disposed in the annular groove 22 on the light shielding layer 2, so that the ambient light can hardly enter the light sensor 5 through the gap between the supporting layer 3 and the light shielding layer 2, the sealing performance of the light transmitting hole 200 can be ensured to the maximum, and the light sensor 5 can only receive the light (such as the ambient light shown in fig. 3) transmitted from the front surface of the cover plate 1, thereby reducing the influence of other factors on the light sensing test of the light sensor 5.

The first aperture 20 comprises a first annular recess 23 provided in the surface of the opacifying layer 2 adjacent the support layer 3, the first annular recess 23 communicating with the first through-hole 21. The supporting layer 3 is partially arranged in the first annular recess 23; that is, the support layer 3 is disposed in the first annular recess 23, and the depth of the first annular recess 23 is smaller than the thickness of the support layer 3.
Specifically, the surface of the support layer 3 close to the light shield layer 2 is a plane, that is, the support layer 3 is a flat structure; the surface of the support layer 3 adjacent to the light-shielding layer 2 is at least partially in contact with the bottom surface of the first annular recess 23; along the thickness direction of the support layer 3, the support layer 3 is partially arranged in the first annular recess 23. The annular width D1 of the support layer 3 may be set to match the width D3 of the first annular recess 23 in the radial direction thereof, so that the support layer 3 can be fitted into the first annular recess 23. In an embodiment, the inner diameter R1 of the support layer 3 is larger than the inner diameter R2 of the first annular recess 23 and smaller than the outer diameter R2 of the first annular recess 23; the external diameter R1 of supporting layer 3 slightly is less than the external diameter R2 of first annular sunken 23 to in supporting layer 3 assembles in first annular sunken 23, and no matter be in ideal assembled state, supporting layer 3 always overlap joint in first annular sunken 23, increased the area of contact of supporting layer 3 with light shield layer 2, and this kind of mode of setting can avoid the slope of light sensor 5, and then avoid the broken problem that the slope of light sensor 5 caused. And the supporting layer 3 is assembled in the first annular recess 23, the ambient light can hardly enter the light sensor 5 through the gap between the supporting layer 3 and the light shielding layer 2, the sealing performance of the light transmitting hole 200 can be ensured to the maximum, the light sensor 5 can only receive the light (the ambient light shown in fig. 4) transmitted from the front surface of the cover plate 1, and the influence of other factors on the light sensing test of the light sensor 5 is reduced.
It is understood that, according to the light sensing FOV characteristic of the light sensor 5, the aperture of the first through hole 21 may be larger than or equal to the aperture of the second through hole 31, without preventing the light sensor 5 from receiving the ambient light.
Referring to fig. 5, fig. 5 is a schematic partial structure diagram of a display device according to a third embodiment of the present application.
In the third embodiment of the display device, the structure of the display device is substantially the same as that of the display device in the first embodiment, except that: the first opening 20 and/or the second opening 30 are disposed in different manners, and the same portions are not described again.
In a third embodiment of the display device, the support layer 3 comprises a ring-shaped body. The second opening 30 includes a second annular recess 32 provided in the support layer 3 near the surface of the light shield layer 2, and the second annular recess 32 is away from the second through hole 31. That is, the second annular recess 32 is located on a side of the annular body away from the second through hole 31. The light shielding layer 2 is at least partially disposed in the second annular recess 32.
Specifically, the surface of the light shielding layer 2 close to the support layer 3 is a plane, that is, the light shielding layer 2 is a flat structure; the surface of the light shielding layer 2 close to the supporting layer 3 is at least partially abutted against the bottom surface of the second annular recess 32; the light shielding layer 2 is at least partially disposed in the second annular recess 32 along the thickness direction of the light shielding layer 2. The thickness of the light shielding layer 2 is matched with the depth of the second annular recess 32 along the axial direction; optionally, the thickness of the light shielding layer 2 is the same as the depth of the second annular recess 32 in the axial direction thereof, so that the light shielding layer 2 is completely disposed in the second annular recess 32 in the thickness direction thereof.
The aperture of the first through hole 21 of the light shielding layer 2 may be matched with the inner diameter r3 of the second annular recess 32, and the light shielding layer 2 may be fitted into the second annular recess 32.

And the light shielding layer 2 is arranged in the second annular recess 32, the ambient light can hardly enter the light sensor 5 through the gap between the supporting layer 3 and the light shielding layer 2, the sealing performance of the light transmitting hole 200 can be ensured to the maximum, the light sensor 5 can only receive the light (the ambient light shown in fig. 5) transmitted from the front surface of the cover plate 1, and the influence of other factors on the light sensing test of the light sensor 5 is reduced.
Referring to fig. 6 to 8, fig. 6 is a schematic partial structure diagram of a display device according to a fourth embodiment of the present disclosure, fig. 7 is a schematic structure diagram of a light shielding layer in fig. 6, and fig. 8 is a schematic structure diagram of a supporting layer in fig. 6.
In a fourth embodiment of the display device, the structure of the display device is substantially the same as that of the display device in the first embodiment, except that: the first opening 20 and/or the second opening 30 are disposed in different manners, and the same portions are not described again.
In a fourth embodiment of the display device, the shading layer 2 is provided with first openings 20 and the support layer 3 is provided with second openings 30. The first opening 20 includes a first annular recess 23 provided on a surface of the light shield layer 2 adjacent to the support layer 3, and the first annular recess 23 communicates with the first through hole 21. The support layer 3 includes an annular body, the second opening 30 includes a second annular recess 32 provided on a surface of the support layer 3 close to the light shielding layer 2, and the second annular recess 32 is away from the second through hole 31, that is, the second annular recess 32 is located on a side of the annular body away from the second through hole 31.
Specifically, a first annular recess 23 is provided on the surface of the light-shielding layer 2 close to the support layer 3, so that a step structure is formed on the light-shielding layer 2; that is, the light shielding layer 2 is formed by the side wall 231 of the first annular recess 23 and the bottom wall 232 of the first annular recess 23, and the side wall 231 of the first annular recess 23 and the bottom wall 232 of the first annular recess 23 cooperate to form a stepped structure (as shown in fig. 7). A second annular recess 32 is formed on the surface of the support layer 3 close to the light shield layer 2, so that a step structure is formed on the support layer 3; that is, the support layer 3 is composed of the side wall 321 of the second annular recess 32 and the bottom wall 322 of the second annular recess 32, and the side wall 321 of the second annular recess 32 and the bottom wall 322 of the second annular recess 32 cooperate to form a stepped structure (as shown in fig. 8). When the light-shielding layer 2 is assembled with the support layer 3, the side wall 321 of the second annular recess 32 abuts against the bottom wall 232 of the first annular recess 23; specifically, the end surface a of the side wall 321 of the second annular recess 32 abuts against the bottom surface b of the first annular recess 23.
