A cellular phone is an electronic device 30 equipped with a cellular communication module.

The technical scheme of this application mainly is to narrow limit screen, bang screen, water droplet screen, dig hole screen etc. 30's comprehensive screen structural scheme improve, further dwindles the leading camera area of screen, realizes that higher screen accounts for than.

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application. Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device 30 according to a first embodiment of the present application. The electronic device 30 of the present application may include a mobile phone, a tablet computer, a notebook computer, a wearable device, and the like. It should be noted that the figures are illustrated with a cell phone as an example, but not limited to a cell phone.

Referring to fig. 1 and 2, fig. 2 is a partial schematic structural diagram of an embodiment of a display assembly 20 according to the present application. An embodiment of the electronic device 30 of the present application includes: a camera assembly 310 and a display assembly 20. The display assembly 20 includes a transparent cover plate 210 and a display panel 10.

In an embodiment of the present application, the display panel 10 includes a light shielding assembly 120 and a functional layer 110, a through hole 1150 is disposed on the functional layer 110, the light shielding assembly 120 at least partially surrounds the through hole 1150, one end of the light shielding assembly is connected to the functional layer 110, and the other end of the light shielding assembly extends into the through hole 1150. For narrow-sided screens, bang screens, and dug screens, the shutter assembly 120 is positioned entirely around the through-hole 1150 because the camera through-hole 1150 is located entirely on the narrow side. And for a drip screen, the shutter assembly 120 partially surrounds the through-hole 1150 because the camera through-hole 1150 is partially abutted against the display area 220 of the display screen.

Referring to fig. 2 and 8, fig. 8 is a schematic structural diagram of the light shielding assembly 120 shown in fig. 1. The light shielding assembly 120 includes a polarizing layer 1210 and a light shielding layer 1230, which are stacked. The polarizing layer 1210 is used for selectively receiving light from the through hole 1150, and the light shielding layer 1230 is used for deflecting the light passing through the polarizing layer 1210 to prevent the light from being reflected out of the through hole 1150. Visible light is a transverse wave whose direction of vibration is perpendicular to the direction of propagation. The vibration direction of natural light is arbitrary in a plane perpendicular to the propagation direction; for polarization, the vibration direction is limited to a specific direction at a certain moment. The polarized light can be classified into three types, i.e., linearly polarized light, elliptically polarized light, and circularly polarized light. The more generally referred to polarization is linear polarization. The polarizing layer 1210 passes light vibrating in a specific direction, but does not pass light vibrating in other directions.

The functional layer 110 includes a connection layer 1110 and a substrate 1130, and the connection layer 1110 is used to connect the transparent cover 210 and the substrate 1130. The transparent cover 210 and the substrate 1130 are typically connected by an adhesive, and the adhesive is an optically transparent adhesive. The optical Clear adhesive of an embodiment of the present application is oca (optical Clear adhesive). The OCA has the advantages of being colorless and transparent, the light transmittance of more than 90 percent, and good bonding strength, is cured at room temperature or medium temperature, has the characteristics of small curing shrinkage and the like, and is a double-sided adhesive tape without a base material. The transparent cover 210 may be made of transparent glass or resin.

Referring to fig. 3, fig. 3 is an enlarged schematic view of a position Y shown in fig. 2. In an embodiment of the present disclosure, the substrate 1130 includes a first base layer 1131, a second base layer 1132 and a third base layer 1133, which are sequentially stacked and away from the light exit side of the through hole 1150. The first base layer 1131 is connected to the connecting layer 1110, and is mainly used for filtering light. The first base layer 1131 is a pol (polarizer) polarizer to dissipate surface reflection and scatter light to increase the viewing angle of the display screen. An electrode and a light emitting material are vapor deposited on the upper surface of the second substrate 1132. The third base layer 1133 is an auxiliary film for supporting, buffering and conducting electricity.

Referring to fig. 3 and 4, fig. 4 is a schematic partial structure view of the glass cover plate shown in fig. 2. In an embodiment of the present application, the shading assembly 120 may be disposed between the connection layer 1110 and the transparent cover plate 210.

That is, a sinking groove 2110 is formed on a side of the transparent cover 210 close to the through hole 1150, and the light shielding assembly 120 is attached to the sinking groove 2110. The size of the counter-sink 2110 matches the size of the shade assembly 120. One end face of the shading component 120 is attached to the sinking groove 2110 through glue, and the other end face is connected with the connecting layer 1110. Since the connecting layer 1110 is a liquid glue or a solid glue, the shading component 120 is only required to be disposed on the transparent cover 210.

In other embodiments, the sinking groove 2110 may not be formed on the transparent cover 210, and the light shielding assembly 120 may be attached to a predetermined position. It should be noted that the connection relationship between the light shielding assembly 120 and the transparent cover 210 in the embodiments of the present application is only described in two embodiments, and other embodiments between the light shielding assembly 120 and the transparent cover 210, which can be easily found by those skilled in the art, are also within the scope of the present application.

With reference to fig. 3, the light is transmitted through the glass cover plate and received by the camera module 310 in the through hole 1150, and under the condition that the angle of view of the camera module is kept unchanged, the diameter of the opening of the through hole 1150 is equal to the diameter a of the opening of the transparent area and the distance B (assuming that there is no gap between the distance B and the distance a) through which the light shielding assembly 120 extends, and B includes B1 and B2 shown in the figure. B1 and B2 are directed toward the inside of the aperture 1150, and the functional layer 110 is directed toward the camera assembly 310, and burrs and the like may be present to reflect light entering through the shutter assembly 120 and then propagate upward from the area of the aperture 1150 under B1 and B2 to be further received by the shutter assembly 120.

Referring to fig. 8 and 9, fig. 9 is a schematic diagram of the light shielding assembly 120 shown in fig. 8. The light shielding layer 1230 of the light shielding assembly 120 is a quarter-wavelength retardation layer, and when external light passes through the polarization layer 1210 from the outside of the through hole 1150, linearly polarized light in one direction is formed, and then when the linearly polarized light passes through the quarter-wavelength retardation layer, the linearly polarized light is converted into right-handed circularly polarized light. When the optical path difference delta is

When passing through the quarter-wave phase difference layer, the light is circularly polarized light

When looking at the propagation direction of light, the rotation direction of the emergent light is clockwise, i.e. the emergent light is right-handed polarized light. When in use

When looking at the direction of light, the rotating direction of the emergent light is anticlockwise, and the emergent light is left-handed circularly polarized light. In an embodiment of the present application, when the propagation direction of the incident light is right-handed circular polarization, the delta value changes after the light is reflected by the functional layer 110, that is, after the light is reflected by the burr and other components in the through hole 1150 regions in B1 and B2, that is, the delta value changes

Become into

The corresponding right-hand polarized light becomes left-hand polarized light, and then the left-hand polarized light becomes linear polarized light after passing through the quarter-wavelength phase difference layer, and the vibration direction of the polarized light at this time is parallel to the absorption axis of the polarizing layer 1210, and the light cannot pass through, thereby ensuring that the burr at the edge of the functional layer 110 in the through-hole 1150 is not visible. Referring to fig. 5, fig. 5 is a schematic diagram of a structure for shielding light by using ink in the prior art. That is, ink is disposed between the transparent glass and the connecting layer 1110, the ink at least partially surrounds the through hole 1150, and an avoiding distance needs to be reserved between the ink and the camera assembly 310 due to silk-screen tolerance of the ink itself or assembly tolerance between the display screen and the camera assembly 310, that is, an avoiding distance exists between a and B, referring to a in the figure, and the diameter of the through hole 1150 needs to be increased due to the existence of the distance a. The distance b in the figure is also larger, and the distance b is the boundary distance of the screen black edge. So arranged, the diameter of the through-hole 1150 may become large. As can be seen from fig. 3 and 5, the present invention eliminates the relief distance, so that the diameter of the through hole 1150 can be reduced, and the burrs at the edge of the functional layer 110 can be eliminated. In the embodiment of the present application, the projection of the maximum field of view boundary of the camera assembly 310 on the transparent glass and the shading assembly 120 on the transparent cover plate 210The projections are at least partially coincident. That is, there is at least no gap between B1 and B2 and the opening diameter a of the via 1150, or at least partial coincidence between the opening diameter a of the via 1150 and B1 and B2. Therefore, when light entering the through hole 1150 is reflected by the functional layer 110 or other components, no gap exists between the A, the B1 and the B2, so that the reflected light can penetrate out of the through hole 1150, and burrs on the edge of the functional layer 110 are not visible.

Referring to fig. 6 and 7, fig. 6 is a partial schematic structural view of another embodiment of the display module 20 of the present application, and fig. 7 is a partial schematic structural view shown in fig. 6. In another embodiment of the present application, the light shielding member 120 may be disposed between the connection layer 1110 and the substrate 1130.

That is, the light shielding element 120 connected to the connection layer 1110 is disposed on the side of the substrate 1130 near the light exit side of the through hole 1150, one end surface of the light shielding element 120 is connected to the substrate 1130 through an adhesive, and the other end is connected to the connection layer 1110. In the embodiment of the present application, the light shielding element 120 is connected to the connection layer 1110 and the substrate 1130 respectively by adhesion, in other embodiments, a sinking groove 2110 may be formed on a side of the substrate 1130 near the light exit side of the through hole 1150, and the light shielding element 120 is attached to the sinking groove 2110. It is understood that the substrate 1130 having the sinking groove 2110 or directly connected to the shading assembly 120 is only two embodiments of the present application, and the connection relationship between the substrate 1130 and the shading assembly 120 is not limited herein, and other connection embodiments between the shading assembly 120 and the substrate 1130 that can be easily obtained by those skilled in the art are also within the scope of the present application.

In other embodiments, the display area 220 is disposed adjacent to the non-display area 230, and the non-display area 230 is disposed around the through hole 1150. It can be concluded that the smaller the non-display area 230 of the display panel 10, the higher the screen occupancy of the display panel 10, which is more beneficial for realizing a full screen or nearly a full screen. Referring to fig. 11, for the narrow-edge screen, the display area 220 is disposed adjacent to the non-display area 230, and the non-display area 230 surrounds the through hole 1150. Referring to fig. 13, for the hole-digging screen, the display area 220 includes a non-display area 230, and the non-display area 230 surrounds the through hole 1150. Referring to fig. 12, for the droplet screen, the display area 220 is disposed adjacent to the non-display area 230, and the non-display area 230 partially surrounds the through hole 1150. Referring to fig. 10, for the bang screen, the display area 220 is disposed adjacent to the non-display area 230, and the non-display area 230 surrounds the through hole 1150. The above-mentioned fig. 10 to 13 are only partial illustrations of the embodiments, and not all embodiments of the present application, if all other embodiments obtained by those skilled in the art without any inventive work fall within the protection scope of the present application.

With continued reference to fig. 1, 2, and 5, the electronic device 30 includes a camera assembly 310, wherein the camera assembly 310 is disposed adjacent to the through hole 1150, and the polarizing layer 1210 at least partially coincides with a projection of a maximum viewing field boundary of the camera assembly 310 on the transparent cover 210, so that light received by the through hole 1150 passes through the light shielding assembly 120 and is not reflected out of the through hole 1150. It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or may alternatively include other steps or elements inherent to such process, method, article, or apparatus.

Specifically, the through hole 1150 functions to allow the camera assembly 310 to collect light, the camera assembly 310 has a viewing angle, the viewing angle of the standard lens is 45 degrees, and a light collecting area is formed at one end of the light emitting side of the through hole 1150 for the camera, and the boundary of the light collecting area corresponds to the maximum viewing field boundary formed by the camera through the through hole 1150. The projection of the polarizing layer 1210 and the maximum viewing field boundary of the camera assembly 310 on the transparent cover plate 210 covering the through hole 1150 is at least partially overlapped, so that light received by the through hole 1150 passes through the light shielding assembly 120 and is not reflected out of the through hole 1150.

In summary, the electronic device 30 provided in the present application includes a camera assembly 310 and a display assembly 20, wherein the display assembly 20 includes a transparent cover 210 and a display panel 10, and the display panel 10 further includes a functional layer 110 and a light shielding assembly 120. The through hole 1150 is disposed in the functional layer 110, and the transparent cover plate 210 is connected to the functional layer 110. The camera assembly 310 receives external light through the through hole 1150 to form an image, and the projection of the maximum field boundary of the camera assembly 310 on the transparent cover plate 210 at least partially coincides with the light shielding assembly 120, so that the light entering the through hole 1150 passes through the light shielding assembly 120 and is not reflected out of the through hole 1150. The light reaches the burr at the edge of the functional layer 110 after passing through the light blocking member 120, and then the light is reflected to the light blocking member 120, but the light reflected outward from the through hole 1150 is extinguished by the light blocking member 120 to block the burr at the edge of the functional layer 110. Compared with the traditional ink design on the transparent cover plate 210, there is a certain distance between the edge of the ink and the maximum field angle of the camera head assembly 310, and the distance makes the diameter of the through hole 1150 become larger, thereby affecting the screen occupation ratio. The maximum view field boundary of the shading component 120 and the camera component 310 adopted by the application is at least partially overlapped with the projection of the transparent cover plate 210, so that the diameter of the through hole 1150 is reduced while the burrs of the functional layer 110 are eliminated, and the screen occupation ratio is further improved.
