[0031] The present disclosure provides an imaging lens assembly module comprising an optical lens assembly and a single-layer light-blocking plate. The optical lens assembly defines an optical axis. The single-layer light-blocking plate is formed by a uniform medium and has a plurality of particles distributed within the uniform medium. The single-layer light-blocking plate comprises an object-side surface, an image-side surface, and a light-blocking surface. The image-side surface is oriented relative to the object-side surface and adjoins an image side of the imaging lens assembly module. The light-blocking surface connects the object-side surface and the image-side surface, and the light-blocking surface is closer to the optical axis than either the object-side surface or the image-side surface is to the optical axis.The appearance of the light-blocking surface is wavy. If the developed interfacial ratio of the light-blocking surface is Sdr and the arithmetic mean of the peak curvature of the light-blocking surface is Spc, then the following conditions are met: 1.5 < Sdr < 25; and 15000 mm. -1 < Spc < 150000 mm -1 In particular, the deformation problem of the light-blocking plate after hardening or assembly can be solved by forming the single-layer light-blocking plate using a uniform medium; however, the present disclosure is not limited to this. If the foregoing conditions are met, the light-blocking surface has a suitable surface roughness. If the surface roughness is too high or too low, light leakage from the imaging lens assembly module or non-imaging light can easily occur.

[0032] In particular, the orientation along the optical axis can be configured to define the object side and the image side of the imaging lens assembly module. The object-side surface, image-side surface, and light-blocking surface of the single-layer light-blocking plate are formed by the uniform medium in which the particles are distributed. This differs from prior art light-blocking plates based on sandwich principles, such as PET, PI, PC, and PMMA sandwiches. The object-side and image-side surfaces of the single-layer light-blocking plate can also be treated by coating, paint coating, laser treatment, or sandblasting to further improve the blocking of non-imaging light.

[0033] The developed interfacial ratio of the present disclosure denotes the incremental ratio of the developed area of ​​the defined region relative to the area of ​​the defined region, and the area of ​​the defined region can be 1000 µm². 2 The present disclosure is not limited to this. The arithmetic mean of the tip curvature of the present disclosure denotes the mean principal curvature of the surface tip.

[0034] A portion of the particles can be exposed via the light-blocking surface. Based on the appearance of the light-blocking surface, which has been treated by embossing, the particle protrusions, the craters left after particle removal, the indentations at the particle edges formed after pressing, and the remaining fragments formed by the split particles are exposed on the light-blocking surface, resulting in a wavy appearance. This prevents the reflection of non-image-generating light from the aforementioned surfaces, thus eliminating glare. It should be noted that the particles are distributed throughout the uniform medium of the single-layer light-blocking plate, not across its surface.

[0035] If the developed interfacial area ratio of the light-blocking surface is Sdr, the following condition is met: 3 < Sdr < 15. Therefore, mass production can be improved under the condition that ensures optical quality. Furthermore, the following condition can be met: 5 < Sdr < 13. Additionally, the following condition can be met: 5.104 ≤ Sdr ≤ 11.45.

[0036] If the arithmetic mean of the tip curvature of the light-blocking surface is Spc, then the following condition is met: 20000 mm -1 < Spc < 100000 mm -1 Therefore, mass production can be improved provided that optical quality is ensured. Furthermore, the following condition can be met: 22000 mm -1 < Spc < 95000 mm -1 Furthermore, the following condition can be met: 25000 mm -1 < Spc < 90000 mm -1 Furthermore, the following condition can be met: 28314.597 mm -1≤ Spc ≤ 72862.323 mm -1 .

[0037] If the diameter of each particle is D, the following condition is met: 0.5 µm < D < 22 µm. Specifically, the diameter is the maximum distance between the particle boundaries, without restriction of direction. If the above condition is met, the roughness of the light-blocking surface can be controlled within a suitable range. If the diameter of each particle is too large or too small, the light-blocking surface may be too smooth or too rough to form non-imaging light. Furthermore, the following condition can be met: 1.0 µm < D < 16 µm. Additionally, the following condition can be met: 1.807 µm < D < 11.110 µm.

[0038] The aforementioned particles can contain silicon dioxide or acrylate material. Therefore, the original material properties of the uniform medium can be modified by adding these particles to increase the hardness of the single-layer light-blocking plate and improve the material's stability.

[0039] If the mean arithmetic height of a surface of the light-blocking surface is Sa, the following condition is met: 0.3 µm < Sa < 2.3 µm. This ensures the appropriate roughness is achieved so that stray light does not easily occur in the imaging lens assembly module. Furthermore, the following condition can be met: 0.45 µm < Sa < 1.8 µm. Additionally, the following condition can be met: 0.636 µm ≤ Sa ≤ 1.144 µm.

[0040] If the gloss difference between the object-side surface and the image-side surface is GL, the following condition is met: 1 GU < GL < 30 GU. Thus, a higher yield rate can be achieved through the manufacturing process of the single-layer light-blocking plate, further improving the assembly yield of the imaging lens assembly module. In detail, gloss is the physical quantity that assesses the ability to reflect light at the material surface under a set of geometrically defined conditions. Gloss is the direction-selective reflective characteristic, and in this disclosure, a gloss meter with a 60-degree angle measurement is selected for measurement. According to ISO 2813, Coatings - Determination of gloss value at 20°, 60° and 85°, 20° is suitable for measuring high-gloss surfaces, 60° for measuring semi-glossy surfaces, and 85° for measuring matte surfaces.Furthermore, the following condition can be met: 2GU < GL < 20GU. Furthermore, the following condition can be met: 3GU < GL < 18GU. It should be noted that surfaces with a matte gloss are relatively rough, and surface static build-up occurs relatively easily on surfaces with a higher gloss value that are relatively smooth. However, deformation or adhesion to other elements during assembly of the single-layer light-blocking panel is possible at extremely low or extremely high gloss levels. Therefore, the above condition is more suitable for the surface of the single-layer light-blocking panel of the present disclosure.

[0041] The light-blocking surface extends continuously around the optical axis to form a light-transmitting aperture in the single-layer light-blocking plate, and the aperture is approximately circular. The aperture can be a polygon formed by connecting a multitude of edges, which may be segments with straight or curved lines; however, the present disclosure is not limited to this. Furthermore, the aperture is approximately circular and can be composed of specific edges such that stray light can be effectively blocked.

[0042] The imaging lens assembly module can further include a light-folding element located on the optical axis, and the light-folding element is configured to fold the optical axis at least once. The single-layer light-blocking plate is positioned on the light-folding element relative to one direction of the optical axis. Therefore, stray light can be blocked within the light-folding element.

[0043] Furthermore, the light-blocking surface can extend in one direction along the optical axis after folding.

[0044] If the surface resistance of the single-layer light-blocking plate is R, the following condition is met: 10 3 Ω / sq < R < 10 8 Ω / sq. The single-layer light-blocking plate consists of uninsulated material, which can be conductive or static-dissipating. Furthermore, the following condition can be met: 10 5Ω / sq < R < 10 7 Ω / sq. Furthermore, if 10 3 Ω / sq < R < 10 5 Ω / sq is fulfilled, the single-layer light-blocking plate is made of conductive material. If 10 6 Ω / sq < R < 10 8 If the Ω / sq requirement is met, the single-layer light-blocking plate consists of statically dissipating material.

[0045] If the thickness of the single-layer light-blocking plate is TH, the following condition is met: 10 µm < TH < 45 µm. If the single-layer light-blocking plate is too thin, the light-blocking effect is reduced. If the single-layer light-blocking plate is too thick, the imaging lens assembly module is too large and heavy. Therefore, by using a single-layer light-blocking plate of a suitable thickness, deformation during assembly or manufacturing can be avoided, and the aforementioned problem can also be prevented. Furthermore, the following condition can be met: 20 µm < TH < 30 µm.

[0046] The present disclosure provides an electronic device comprising the aforementioned imaging lens assembly module.

[0047] The present disclosure provides an imaging lens assembly module comprising an optical lens assembly and a variable aperture module. The optical lens assembly defines an optical axis. The variable aperture module comprises a plurality of single-layer light-blocking plates arranged around a circumferential direction of the optical axis to form a light-transmitting aperture, the size of which is variable. Each of the single-layer light-blocking plates is formed by a uniform medium and has a plurality of particles distributed within the uniform medium. Each of the single-layer light-blocking plates comprises an object-side surface, an image-side surface, and a light-blocking surface. The image-side surface is arranged relative to the object-side surface and adjoins an image side of the imaging lens assembly module.The light-blocking surface connects the object-side surface and the image-side surface. The light-blocking surface extends around the circumference of the optical axis and is connected to another light-blocking surface when viewed along a direction of the optical axis. The light-blocking surface appears wavy. In detail, the deformation problem of the light-blocking plate after hardening or assembly can be solved by forming the single-layer light-blocking plate using a uniform medium; however, the present disclosure is not limited to this.

[0048] In particular, the variable aperture module can be arranged on the outermost object side of the optical lens arrangement or between optical lens elements of the optical lens arrangement; however, the present disclosure is not limited to this.

[0049] The object-side surface, image-side surface, and light-blocking surface of each of the single-layer light-blocking plates are formed entirely by the uniform medium in which the particles are distributed. This differs from prior art light-blocking plates based on sandwich principles, such as PET sandwiches, PI sandwiches, PC sandwiches, and PMMA sandwiches. The object-side and image-side surfaces of each of the single-layer light-blocking plates can also be treated by coating, paint coating, laser treatment, or sandblasting to further improve the blocking of non-image-emitting light.

[0050] A portion of the particles can be exposed via the light-blocking surface. Based on the appearance of the light-blocking surface, which has been treated by embossing, the particle protrusions, the craters left after particle removal, the indentations at the particle edges formed after pressing, and the remaining fragments formed by the split particles are exposed on the light-blocking surface, resulting in a wavy appearance. This prevents the reflection of non-image-generating light from the aforementioned surfaces, thus eliminating glare. It should be noted that the particles are uniformly distributed throughout each of the single-layer light-blocking plates, rather than being distributed across a single surface. The light-blocking surface surrounds the optical axis to form the light-transmitting aperture.

[0051] Each of the single-layer light-blocking plates can further include a positioning aperture and a rotation aperture. The positioning aperture can be configured to position the single-layer light-blocking plates on the variable aperture module, and the rotation aperture is configured to provide a movement path to ensure that the single-layer light-blocking plates are movable, allowing the size of the light-transmitting aperture to be changed.

[0052] Furthermore, a positioning aperture differs from a rotating aperture in that the positioning aperture can be a round opening and the rotating aperture can be a strip-shaped opening that extends in one direction of the light transmission aperture.

[0053] If the developed surface area ratio of the light-blocking surface is Sdr, the following condition is met: 1 < Sdr < 25. This allows the light-blocking surface to have the appropriate surface roughness. If the roughness is too high or too low, light leakage from the imaging lens assembly module or non-imaging light can easily occur. Furthermore, the following condition may be met: 3 < Sdr < 15. Additionally, the following condition may be met: 5 < Sdr < 13.

[0054] If the arithmetic mean of the tip curvature of the light-blocking surface is Spc, then the following condition is met: 15000 mm -1 < Spc < 150000 mm -1This allows the light-blocking surface to have the appropriate surface roughness. If the roughness is too high or too low, light leakage from the imaging lens assembly module or non-image light can easily occur. Furthermore, the following condition may be met: 20,000 mm -1 < Spc < 100000 mm -1 Furthermore, the following condition can be met: 22000 mm -1 < Spc < 95000 mm -1 Furthermore, the following condition can be met: 25000 mm -1 < Spc < 90000 mm -1 .

[0055] If the diameter of each particle is D, the following condition is met: 0.5 µm < D < 22 µm. This allows the roughness of the light-blocking surface to be controlled within a suitable range. If the diameter of each particle is too large or too small, the light-blocking surface may be too smooth or too rough to form non-imaging light. Furthermore, the following condition can be met: 1.0 µm < D < 16 µm.

[0056] The aforementioned particles can contain silicon dioxide or acrylate material. Therefore, the original material properties of the uniform medium can be modified by adding these particles to increase the hardness of each single-layer light-blocking plate and improve the material's stability.

[0057] If the mean arithmetic height of a surface of the light-blocking surface is Sa, the following condition is met: 0.3 µm < Sa < 2.3 µm. This ensures the appropriate roughness is achieved so that stray light does not easily occur in the imaging lens assembly module. Furthermore, the following condition can also be met: 0.45 µm < Sa < 1.8 µm.

[0058] If the surface resistance of each of the single-layer light-blocking plates is R, then the following condition is met: 10 3 Ω / sq < R < 10 8 Ω / sq. Each of the single-layer light-blocking plates consists of uninsulated material, which can be conductive or static-dissipating. Furthermore, the following condition can be met: 10 5 Ω / sq < R < 10 7 Ω / sq. Furthermore, if 10 3 Ω / sq < R < 10 5 Ω / sq is satisfied, each of the single-layer light-blocking plates made of conductive material. If 10 6Ω / sq < R < 10 8 If the Ω / sq requirement is met, each of the single-layer light-blocking plates consists of statically dissipating material.
