In this way, the substrate 22 can also be used to support the surface transparent lens 21, so as to improve the structural strength of the optical lens assembly 2, thereby preventing the surface transparent lens 21 from being damaged during the use process.

The substrate 22 is formed with at least one through hole 221. The at least one through hole 221 forms at least one first transmissive region 261 and/or at least one second transmissive region 262. In other words, the first light-transmitting region 261 is formed by the through-hole 221, and/or the second light-transmitting region 262 is formed by the through-hole 221. In some embodiments, the at least one through hole 221 formed in the substrate 22 forms at least one first light-transmitting region 261, and when the through hole 221 is plural, the plural through holes 221 form plural first light-transmitting regions 261.

First clear region 261 allows light to pass through to reach the first surface of surface clear lens 21. That is, the through holes 221 formed in the substrate 22 at least include a first through hole forming the first light-transmitting region 261, in other words, the first light-transmitting region of the light-crosstalk prevention layer is opposite to at least one through hole 221 formed in the substrate 22, so that the light emitted by the light-emitting element 1 can pass through the first through hole formed in the substrate 22 to reach the first surface of the surface layer light-transmitting lens 21, and meanwhile, the light-shielding layer 27 on the substrate 22 prevents the light from passing through the region other than the first through hole on the substrate 22 to cause the light crosstalk phenomenon, which interferes with the light received by the receiving element 3.

In the embodiment shown in fig. 6-8, two through holes 221 (first through holes) are formed in the substrate 22, and the two through holes 221 form two first light-transmitting regions 261 respectively opposite to the two light-emitting elements 1. Of course, in other embodiments, the at least one through hole 221 formed in the substrate 22 may further include at least one second through hole, and the second through hole forms the second light-transmitting area 262, so as to allow the light of the first surface of the surface light-transmitting lens 21 to pass through the second through hole to reach the receiving element 3.

Further, as shown in fig. 6 to 8, a light shielding region is provided at the periphery of at least a portion of at least one through hole 221. That is, the light shielding layer 27 is provided on the periphery of at least a part of the at least one through hole 221. In some embodiments, the light shielding layer 27 is disposed at the periphery of a portion of the at least one through hole 221 and between the first transparent region 261 and the second transparent region 262, so as to prevent light of the first transparent region 261 and light of the second transparent region 262 from being interfered with each other. In other embodiments, the light shielding layer 27 surrounds the periphery of the at least one through hole 221. For example, as shown in the rear view of the optical lens assembly 2 in fig. 8, the light shielding layer 27 is two annular light shielding layers respectively disposed around the two through holes 221 (first through holes) and located between the first transparent region 261 and the second transparent region 262, so as to effectively prevent light from passing from the first transparent region 261 to the second transparent region 262 or light from passing from the second transparent region 262 to the first transparent region 261 to interfere with the emission and reception of light.

Further, as shown in fig. 6-8, the inner sidewall surface of the through hole 221 is provided with a light shielding material 24, and the light shielding material 24 is used for preventing light from entering the substrate 22 from the sidewall of the through hole 221 and propagating along the substrate 22 to cause crosstalk. Optionally, the light shielding material 24 is a light shielding ink, and the light shielding ink is coated on the inner sidewall surface of the through hole 221. Preferably, the light-shielding ink is black, which has a better light-blocking effect.

In some embodiments, an ink layer may be further disposed on the first surface of the surface layer light-transmitting lens 21, the ink in the ink layer corresponds to the light-shielding region of the light-crosstalk-preventing layer, the ink layer is located between the surface layer light-transmitting lens 21 and the substrate 22, and is used for shielding the optical sensor inside the electronic device, and shielding the sight of the user, so as to prevent the user from seeing the optical sensor inside the electronic device through the surface layer light-transmitting lens 21 and the light-transmitting base 22, thereby improving the appearance consistency and the aesthetic property of the electronic device, and meanwhile, because the ink layer corresponds to the light-shielding region of the light-crosstalk-preventing layer, the setting of the ink layer can be prevented from affecting the transmission of light.

In other embodiments, the substrate 22 is an opaque plate, a plurality of through holes 221 are formed on the substrate 22, and the plurality of through holes 221 form the plurality of light-transmitting regions 26. Specifically, the base 22 is formed with at least one first through hole and at least one second through hole, the first through hole forms a first light-transmitting region 261 opposite to the light emitting element 1, and the second through hole forms a second light-transmitting region 262 opposite to the receiving element 3. The light reaches the first surface of the surface layer light-transmitting lens 21 through the first through hole, and the reflected light from the first surface of the surface layer light-transmitting lens 21 reaches the receiving element 3 through the second through hole.

In some embodiments, as shown in fig. 6-8, the cover lens 21 and the substrate 22 are connected by a glue layer 23.

In some embodiments, the thickness of the substrate 22 is greater than 0.5 mm, so that the thickness of the substrate 22 is greater than 0.5 mm, and thus the substrate 22 has stronger structural strength, and can support the surface transparent lens 21 more effectively, thereby improving the structural strength of the optical lens assembly 2.

Optionally, the substrate 22 is a glass lens, a sapphire lens, or a plastic sheet.

In some embodiments, the substrate 22 and the surface light-transmitting lens 21 are made of the same material, and the thickness of the substrate 22 is greater than that of the surface light-transmitting lens 21, so that the thickness of the substrate 22 is greater than that of the surface light-transmitting lens 21, and thus the substrate 22 has stronger structural strength compared with the surface light-transmitting lens 21, and can effectively support the surface light-transmitting lens 21.

The optical lens assembly 2 in the above embodiment is applied to an electronic device, as shown in fig. 9, the substrate 22 is located above the surface layer light-transmitting lens 21, one end of the light-sealing member 5 close to the optical lens assembly 2 abuts against the substrate 22, the fresnel pattern film 4 is fitted inside the light-sealing member 5 and located between the optical lens assembly 2 and the light-emitting element 1, light rays downwards sequentially pass through the fresnel pattern film 4, the through hole 221 (first through hole) of the substrate 22 and the surface layer light-transmitting lens 21, the light rays penetrate through the emitting positions of the fresnel pattern film 4 and the surface layer light-transmitting lens 21, and are blocked by the light-sealing member 5, the light-shielding layer 27 and the light-shielding material 24 coated on the side wall of the through hole 221 in the process, so that the occurrence of the crosstalk problem is effectively avoided.

In the following, an optical lens assembly 2 according to other embodiments of the present invention is described by way of example with reference to fig. 10.

In some embodiments, the optical lens assembly 2 further includes a light shielding component 211, as shown in fig. 10, the light shielding component 211 is disposed inside the surface light-transmitting lens 21 and extends along the thickness direction of the surface light-transmitting lens 21, for example, the light shielding component 211 may extend from the first surface to the second surface of the surface light-transmitting lens 21, or the light shielding component 211 may be located in a portion of the surface light-transmitting lens 21 in the thickness direction, for example, a certain distance from the first surface and/or the second surface, and may be specifically disposed according to a specific light crosstalk condition, which is not limited in the embodiments of the present disclosure. The light shielding member 211 is disposed at a boundary area between at least one light transmitting area among the plurality of light transmitting areas of the light crosstalk preventing layer and the light shielding area. The light shielding part 211 can isolate the light from the transverse light crosstalk inside the surface layer light-transmitting lens 21, so that the electronic device can more accurately measure the physiological parameters of the human body, such as blood oxygen, heart rate and the like. The light-crosstalk-preventing layer may be the light-crosstalk-preventing layer in any of the above embodiments, and is not limited herein.

As an example, the light shielding member 211 may have a ring shape, and the ring-shaped light shielding member 211 divides the surface layer light transmitting lens 21 into a first surface layer light transmitting lens and a second surface layer light transmitting lens, the first surface layer light transmitting lens being located inside the light shielding member 211, the first surface layer light transmitting lens being opposite to the first light transmitting area 261, that is, opposite to the light emitting element 1, and the second surface layer light transmitting lens being located outside the light shielding member 211, and opposite to the second light transmitting area 262, that is, opposite to the receiving element 3. The light emitted by the light emitting element 1 reaches the first surface of the first surface layer light transmission lens through the first light transmission region 261, and is emitted from the first surface to the second surface along the first surface layer light transmission lens, and in the process, due to the complete blocking of the light blocking part 211, the light cannot be transmitted to the second surface layer light transmission lens, so that the light reception is interfered.

Alternatively, the surface layer transmission lens 21 and the light shielding member 211 are integrally molded by a sintering process, that is, they are integrated.

Alternatively, the surface layer light-transmitting lens 21 and the light-shielding member 211 are made of the same material. The light shielding member 211 is made of glass, sapphire or plastic.
