Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In one aspect of the invention, a screen cover is provided. Referring to fig. 1 and 2 (fig. 2 is a cross-sectional view along direction AA' of fig. 1), the screen cover 1000 includes: the image sensor includes a substrate 100 and an ink layer 200, where the substrate 100 defines a camera area 110 and a camera frame area 120, the camera frame area 120 is disposed around the camera area 110, the ink layer 200 covers the camera frame area 120 (for example, referring to fig. 2, the ink layer 200 covers the camera frame areas 120A and 120B), a light transmittance of the ink layer 200 is not greater than 10%, and the ink layer 200 has light guide particles 10. Therefore, when the screen cover 1000 is used in an electronic device, on one hand, the ink layer 200 can shield the edges of the camera body and the visible film material around the camera hole, and prevent light leakage caused by hole digging on the display screen, and on the other hand, the light guide particles 10 in the ink layer 200 can guide light emitted by the display screen outwards, change the light propagation direction and enable the light to be emitted from the upper side of the camera frame area 120, so that the range of the camera frame is visually reduced, the appearance effect of a narrow frame or even no frame of the camera assembly is achieved, the range of the display screen is expanded, and the visual impact effect and the product expressive force of the electronic device are improved (even the light emitted by the display screen near the camera frame area 120A or 120B is directed to the camera area).
For convenience of understanding, the following describes the principle that the screen cover according to the embodiment of the present invention can achieve the above technical effects:
as mentioned above, in the current electronic device with an in-screen camera, a screen cover plate is usually disposed above a display screen, and a shielding ink layer is printed on the screen cover plate in an area corresponding to a camera frame to shield the edges of a camera body and a visible film material below the screen cover plate and prevent light leakage caused by hole digging on the display screen. The back in the display screen is installed to the camera subassembly, and from the vision, the diameter in camera hole equals transparent camera lens body diameter and the width on camera frame district printing ink layer to the camera hole looks very big, is unfavorable for the screen design of camera narrow frame and no frame, reduces the visual impact effect of display screen. According to the screen cover plate provided by the embodiment of the invention, through designing the ink layer of the screen cover plate, on one hand, the light transmittance of the ink layer is not more than 10%, namely, the ink layer can better shield the camera main body around the camera hole and the edge of the visible film material, and prevent light leakage and the like caused by hole digging on the display screen; on the other hand, when the screen cover 1000 is used in an electronic device (the display screen of the electronic device can be located below the substrate 100 shown in fig. 2), referring to fig. 2, the light-guiding particles 10 in the ink layer 200 can guide the light emitted from the display screen (not shown) outwards (i.e. when the light near the edge of the display screen of the camera frame is incident on the light-guiding particles 10, the light can be diffused in all directions, the outward conduction refers to the light emitted from the edge of the display screen near the camera frame is emitted from the direction far away from the display screen on the substrate 100, i.e. from the camera frame area 120), the light propagation direction is changed and the light is emitted from the top of the screen cover (the light propagation direction refers to the directions shown by the dotted lines and arrows in fig. 2), so that the light and the image at the edge of the display screen seen by the user can be extended outwards from the view, even if the range of the display screen is expanded to the camera frame areas 120A and 120B, the range of the display screen is visually expanded, and the range of the camera frame (namely the range of the camera frame area 120) is reduced, so that the appearance effect of a camera assembly with a narrow frame or even no frame is achieved, the visual impact effect and the product expressive force of electronic equipment are improved, and the method is simple in manufacturing process and does not influence the use performance of the camera and the reliability of the display screen.
According to an embodiment of the present invention, the substrate 100 is formed of a transparent material, and particularly, may be formed of glass, transparent plastic, or the like. According to the embodiment of the present invention, the substrate 100 defines the camera area 110 and the camera frame area 120, the camera frame area 120 is disposed around the camera area 110, when the screen cover is used in an electronic device, the camera hole is exposed on the outer surface of the display screen of the electronic device, that is, the transparent camera area 110 on the substrate 100 is disposed above the camera hole, so that the camera hole can shoot through the transparent camera area 110 above, and the camera frame area 120 can shield the edges of the camera body and the visible film material, and prevent light leakage caused by the hole digging on the display screen.
According to the embodiment of the invention, the light transmittance of the ink layer 200 is not more than 10%, so that the ink layer 200 can better shield the edges of the camera main body and the visible film material, prevent light leakage and the like caused by hole digging on the display screen, and improve the appearance and the service performance of the display screen. Specifically, the light transmittance of the ink layer 200 may be not greater than 8%, may be not greater than 5%, may be not greater than 2%, and the like. According to an embodiment of the present invention, the ink layer 200 may be formed of a shielding ink, that is, an ink having a small light transmittance (for example, a light transmittance of not more than 10%), and specifically, the color of the shielding ink is not particularly limited, and may be black, or may be gray, white, or the like. Specifically, after the light of the display screen is emitted from the upper side of the camera frame area 120 through the scattering of the light guide particles 10, when the ink layer 200 is formed by white shielding ink, the white shielding ink does not interfere with the emitted light and the extended image at the edge of the display screen, thereby further improving the visual effect of the electronic device.
According to the embodiment of the present invention, the ink layer 200 has the light-guiding particles 10, and specifically, the specific type and size of the light-guiding particles 10 are not particularly limited as long as the good "light-guiding" effect can be achieved, i.e., the propagation direction of light incident from the edge of the display screen to the light-guiding particles can be changed, and light can be emitted from the upper side of the camera frame area 120. Specifically, the light guide particles 10 may be transparent light guide powder, such as silicone resin particles, and after the light guide particles formed from the transparent light guide powder are added into the shielding ink to form the ink layer 200, the light guide particles 10 are colorless, transparent or translucent, so that the overall color and appearance of the ink layer 200 are not affected by the incorporation of the light guide particles 10, and the appearance integrity of the electronic device is further improved. Specifically, the light guide particles 10 may have a particle size of several nanometers to several micrometers, so that the light guide particles have a better use effect. According to the embodiment of the present invention, the content of the light guide particles 10 in the shielding ink may be 1 to 30 wt%, specifically, 2 wt%, 5 wt%, 8 wt%, 10 wt%, 12 wt%, 15 wt%, 20 wt%, 25 wt%, or the like, and thus, when the addition ratio of the light guide particles 10 (i.e., the weight percentage of the light guide particles 10 in the shielding ink) is within the above range, a good light guide effect may be obtained, and the appearance effect of the ink layer 200 itself may not be affected.
According to an embodiment of the present invention, the arrangement manner of the light-guiding particles 10 in the ink layer 200 is not particularly limited, and for example, as described above, the light-guiding particles 10 may be directly added to the shielding ink so as to form the ink layer 200. Specifically, referring to fig. 3, the ink layer 200 may further include a light-guiding ink sublayer 210 disposed on one side of the substrate 100 (i.e., disposed below the substrate 100), and a shielding sublayer 220 disposed on one side of the light-guiding ink sublayer 210 away from the substrate 100 (i.e., disposed below the light-guiding ink sublayer 210) having the light-guiding particles 10 therein. Therefore, the shielding sublayer 220 can better shield the edges of the camera body and the visual film material, and prevent light leakage and the like caused by hole digging on the display screen, the light guide ink sublayer 210 with the light guide particles 10 can guide light emitted from the edges of the display screen outwards, change the light propagation direction and enable light rays to be emitted from the upper part of the camera frame area 120, and visually reduce the range of the camera frame, so that the appearance effect of the camera assembly with a narrow frame or even no frame is achieved, the range of the display screen is expanded, and the visual impact effect and the product expressive force of electronic equipment are improved.
According to the embodiment of the present invention, the specific material and the forming manner of the shielding sublayer 220 are not particularly limited as long as the light transmittance of the shielding sublayer 220 is low (for example, the light transmittance is not more than 10%), which can better shield the edges of the camera body and the visible film material, and prevent light leakage caused by hole digging on the display screen, and the like. Specifically, the shielding sub-layer 220 may be formed of shielding ink or a shielding film. That is, the shielding sublayer 220 may be formed by printing shielding ink on the surface of the light guide ink sublayer 210 away from the substrate 100, or may be formed by directly adhering a shielding film material to the surface of the light guide ink sublayer 210 away from the substrate 100, specifically, the shielding film material may be a film material on which shielding ink and the like are printed in advance, and when the screen cover according to the embodiment of the present invention is manufactured, the shielding film material may be directly adhered to the surface of the light guide ink sublayer 210 away from the substrate 100. Specifically, the light transmittance of the shielding sublayer 220 may be not more than 10%, and the color of the shielding sublayer 220 may be black, or gray, white, or the like.
According to the embodiment of the present invention, the light guide ink sub-layer 210 may be transparent, that is, the light transmittance of the light guide ink sub-layer 210 may be not less than 90%, may be not less than 95%, and the like, so that, on one hand, the light guide ink sub-layer 210 may better enable incident light at the edge of the display screen to be emitted from above the camera frame region 120, thereby improving the visual effect of the display screen; on the other hand, the transparent light-guiding ink sub-layer 210 does not interfere with the color, appearance and the like of the lower shielding sub-layer 220, and the appearance effect of the electronic device is further improved. According to an embodiment of the present invention, the light guiding ink sub-layer 210 may have a thickness of 2 to 20 μm, for example, 5 μm, 10 μm, 15 μm, etc., and the shielding sub-layer 220 may have a thickness of 4 to 40 μm, for example, 5 μm, 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, etc. Therefore, the light guide ink sublayer 210 and the shielding sublayer 220 with the thickness can better shield the edges of the camera main body and the visible film material, prevent light leakage and the like caused by hole digging on the display screen, and enable light rays at the edges of the display screen to be emitted from the upper side of the camera frame area 120, so that the range of the camera frame area 120 is visually reduced, the narrow frame or even frameless design of the camera assembly is realized, and the visual effect of the electronic equipment is improved. According to an embodiment of the present invention, the content of the light-guiding particles in the light-guiding ink sub-layer 210 may be 30 to 80 wt%, for example, may be 40 wt%, may be 50 wt%, may be 60 wt%, may be 70 wt%, and the like. Therefore, when the ink layer comprises the light guide ink sub-layer and the shielding sub-layer, the content of light guide particles in the ink layer can be higher, so that the light guide performance is further improved, the range of the camera frame area is further smaller visually, and the visual effect of the electronic equipment is improved.
According to an embodiment of the present invention, the orthographic projection of the shielding sublayer 220 on the substrate 100 may cover the camera frame region 120, the light-guiding ink sublayer 210 may cover the camera frame region 120 (as shown in fig. 3), and the light-guiding ink sublayer 210 may also cover at most a portion of the camera frame region 120 away from the camera region 110 (as shown in reference to fig. 4). Specifically, the light guide ink sublayer 210 only covers at most a part of the area of the camera frame area 120 far from the camera area 110, that is, the light guide particles are not disposed on the camera frame area 120 close to the camera area 110, so that, on one hand, the area of the light guide ink sublayer 210 is covered on the camera frame area 120, and the light guide particles 10 therein can better conduct the light on the screen edge close to the camera frame area 120, so as to visually reduce the range of the camera frame area 120 and improve the visual effect of the display screen; on the other hand, the area of the camera frame area 120 not covered by the light guide ink sublayer does not contain light guide particles, so that the light guide intensity of the area is not large (i.e., the amount of light emitted from the area at the edge of the screen is not large), and therefore, the imaging effect of the camera is not affected, i.e., the imaging is not affected by external light, and the use performance of the camera assembly using the screen cover plate and the electronic device is further improved.
According to an embodiment of the present invention, referring to fig. 5 and fig. 6 (fig. 6 is a schematic cross-sectional structure along the direction BB' in fig. 5), a display area 130 and a non-display area 140 may be further defined on the substrate 100, the non-display area 140 is disposed around the display area 130, the camera area 110 and the camera frame area 120 are disposed in the display area 130, and the ink layer 200 covers the camera frame area 120 and the non-display area 140. Therefore, when the screen cover 1000 is used in an electronic device, on one hand, as described above, the ink layer 200 disposed in the camera frame region 120 (refer to the camera frame regions 120A and 120B shown in fig. 6) can not only shield the edges of the camera body and the visible film material around the camera hole, and prevent light leakage and the like caused by hole digging on the display screen, but also the light guide particles 10 in the ink layer 200 can guide light emitted by the display screen outward, change the light propagation direction, and make light emit from above the camera frame region 120, so as to visually reduce the range of the camera frame, thereby achieving the appearance effect of the camera assembly being a narrow frame or even a frame-less frame, expanding the range of the display screen, and improving the visual impact effect and product expressive force of the electronic device; on the other hand, the ink layer 200 disposed in the non-display area 140 (refer to the non-display areas 140A and 140B shown in fig. 6) can shield the driving circuit routing, the package frame, and the like around the display screen, and the light guide particles 10 in the ink layer 200 can guide the light emitted by the display screen outwards, change the propagation direction of the light, and emit the light from above the non-display area 140, so that the frame range of the screen is visually reduced, thereby achieving the appearance effect of a narrow frame or even no frame of the display screen, and further improving the visual impact effect and the product expressive force of the electronic device.
In another aspect of the present invention, a method of making a screen cover is provided. According to an embodiment of the present invention, the screen cover manufactured by the method may be the screen cover described above, and thus, the screen cover manufactured by the method has all the features and advantages of the screen cover described above, and will not be described herein again. In general, when the screen cover plate manufactured by the method is used in electronic equipment, the range of a camera frame of a camera assembly in a screen can be visually reduced, so that the appearance effect of a narrow frame or even no frame of the camera assembly is achieved, the range of a display screen is expanded, and the visual impact effect and the product expressive force of the electronic equipment are improved. Specifically, referring to fig. 7, the method includes:
s100: providing a substrate
In this step, a substrate is provided. According to an embodiment of the present invention, a specific type of the substrate is not particularly limited, and the substrate may be formed of a transparent material, specifically, glass, transparent plastic, or the like.

S200: printing ink on a substrate to form an ink layer
In this step, ink is printed in the camera frame area of the substrate described previously so as to form an ink layer. According to the embodiment of the invention, the light transmittance of the ink layer is not more than 10%, and the ink layer is provided with the light guide particles. Therefore, the light guide particles can guide light emitted by the display screen outwards, change the light propagation direction and enable the light to be emitted from the upper side of the camera frame area, the range of the camera frame is visually reduced, the appearance effect of a camera narrow frame or even no frame is achieved, the range of the display screen is expanded, and the visual impact effect and the product expressive force of electronic equipment are improved. According to the embodiment of the present invention, the method for making the ink layer is not particularly limited, for example, the light guide particles may be added to the masking ink to form a raw material for making the ink layer, and then the masking ink with the light guide particles added thereto may be printed on the camera frame area of the substrate, specifically, the ink may be printed on the substrate by screen printing. Specifically, the specific type, size, and addition ratio of the light-guiding particles may be the same as those described above, and will not be described herein again, for example, the addition ratio of the light-guiding particles (i.e., the weight percentage of the light-guiding particles in the shielding ink) may be 1-30 wt%.
According to further embodiments of the present invention, referring to fig. 8, printing an ink layer on a substrate may also include the steps of:
s210: forming a light-guiding ink sub-layer
In this step, the light-directing ink is printed in the camera frame area of the previously described substrate to form a light-directing ink sub-layer. Specifically, the light guide ink sub-layer may be formed by a screen printing method. According to an embodiment of the present invention, the light-guiding ink has the light-guiding particles described above therein. Therefore, the light guide ink sublayer can enable incident light at the edge of the display screen to be emitted from the upper side of the camera frame area well, and the visual effect of the display screen is improved. Specifically, the specific type of the light guide ink sublayer may be the same as that described above, and is not described herein again, specifically, the light guide ink sublayer may be transparent, the light transmittance of the light guide ink sublayer may be not less than 90%, the thickness of the light guide ink sublayer may be 2 to 20 μm, and the light guide ink sublayer may only cover a part of the region of the camera frame region away from the camera region, and the like. According to embodiments of the present invention, the light-guiding particles may be present in the light-guiding ink sub-layer in an amount of 30 to 80 wt%.

Specifically, the masking film may be a film on which masking ink or the like is printed in advance, and may be, for example, a polyethylene terephthalate (PET) film on which masking ink is printed in advance. Specifically, the shielding sub-layer may be formed by a screen printing method.
