Description

[0001] This application is a divisional application. The original application was filed on April 1, 2021; the application number is 202110355343.X; and the invention title is: Light-transforming element for camera module, camera module and electronic device. Technical Field

[0002] The present invention relates to a light-transforming element, a camera module, and an electronic device, particularly a camera module suitable for an electronic device and a light-transforming element for a camera module. Background Technology

[0003] With advancements in semiconductor technology, the performance of electronic image sensors has improved, allowing pixels to reach smaller sizes. Therefore, optical lenses with high image quality have become an indispensable component. Furthermore, with the rapid development of technology, mobile devices equipped with optical lenses are being used in a wider range of applications, leading to more diverse requirements for these lenses.

[0004] In recent years, electronic products have been trending towards thinner and lighter designs. However, traditional optical lenses, especially telephoto lenses, can no longer simultaneously meet the demands for miniaturization and high image quality. Existing telephoto lenses suffer from drawbacks such as excessive length, insufficient image quality, or excessive size, thus failing to meet current market demands. Therefore, by configuring optical lenses with optical axis reversal, the size in one direction can be reduced, thereby decreasing the overall volume. However, under diffraction-limited conditions, stray light generated by optical lenses has a significant impact on image quality, inherently limiting the resolution of optical lenses. Furthermore, in the injection molding process for manufacturing optical reversing elements, the conventional shape of these elements is prone to mold adhesion, which hinders mold release during molding and may result in uneven optical surfaces, reducing product yield and efficiency.

[0005] Therefore, how to improve optical lenses to reduce their size while simultaneously achieving the goals of blocking stray light and improving the feasibility of mold release during the molding of light-converting elements, in order to meet the high-specification requirements of today's electronic devices, has become an important issue in the relevant field. Summary of the Invention

[0085] The following detailed description of the features and advantages of the present invention in the embodiments is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Based on the disclosure of this specification, the scope of protection of the claims, and the accompanying drawings, any person skilled in the art can easily understand the related objects and advantages of the present invention. The following embodiments further illustrate the viewpoints of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

[0086] This invention provides an optical reversing element for a camera module, comprising an object-side surface, an image-side surface, at least one reflective surface, and at least one connecting surface. Imaging light entering the camera module is incident on the object-side surface of the optical reversing element, and the imaging light exits from the image-side surface of the optical reversing element. The imaging light is imaged onto the imaging surface of the camera module through the imaging lens. The imaging light may pass through the imaging lens of the camera module first and then through the optical reversing element, or it may pass through the optical reversing element first and then through the imaging lens; this invention is not limited to this. The optical reversing element may be made of plastic material.

[0087] The reflecting surface is used to reflect imaging light rays passing through the object side to the image side, and the connecting surface connects the object side, the image side, and the reflecting surface. The reflecting surface can reflect imaging light rays through a high-reflectivity film layer or through total internal reflection; this invention is not limited to these methods.

[0088] The optical reversing element has at least one recessed structure located on the connecting surface, and the recessed structure recesses from the connecting surface toward the interior of the optical reversing element. The recessed structure on the connecting surface includes a top portion, a bottom portion, and a tapered portion. The top portion is adjacent to an edge of the connecting surface, the bottom portion is opposite to the top portion, and the tapered portion connects the top portion and the bottom portion and is located between them. The tapered portion has two tapered edges on the connecting surface, connecting the top portion and the bottom portion, and the width of the tapered portion gradually decreases from the top portion to the bottom portion. The recessed structure can be formed in a trapezoidal shape or a triangular shape on the same plane as the connecting surface; this invention is not limited to this. The edge of the connecting surface can refer to the junction of the connecting surface and the object side, image side, or reflecting surface.

[0089] The light-reflecting element for camera modules disclosed in this invention features a recessed structure design that enables mold release during injection molding of the light-reflecting element. Furthermore, the recessed structure, which descends from the connecting surface, improves product yield and enhances the flatness of optical surfaces such as the object side, image side, and reflecting surface. In addition, this recessed structure can also shield stray light within the light-reflecting element.

[0090] The width of the top end of the concave structure is Wt, and the width of the bottom end is Wb, which satisfies the following condition: 0 ≤ Wb / Wt < 1. This provides higher release efficiency and increases production capacity. When the concave structure is triangular, the width of the bottom end is zero, i.e., Wb = 0. Please refer to... Figure 7 The diagram illustrates parameters Wt and Wb according to the first embodiment of the present invention.

[0091] The two tapered edges of the tapered section form an included angle α, which satisfies the following condition: 2 degrees ≤ α ≤ 150 degrees. This provides the necessary release angle for mold release, reducing the chance of mold sticking. Please refer to... Figure 7 The diagram illustrates a parameter α according to the first embodiment of the present invention.

[0092] The optical switching element may be provided with a light-absorbing layer, and at least a portion of the light-absorbing layer is disposed in a recessed structure. This improves the efficiency of blocking stray light. The light-absorbing layer is an opaque material with a specific optical density, and it can be deposited on the surface of the optical switching element by coating, ink coating, or development. Furthermore, the light-absorbing layer can be a blackened coating layer, a black ink coating layer, or a photoresist layer, but the invention is not limited thereto. The photoresist layer can be further divided into positive photoresist and negative photoresist, and appropriate processes can be selected according to different design requirements.

[0093] The recessed structure can have two slopes, which approach each other from the two tapered edges toward the interior of the light-transforming element. This facilitates the application of the light-absorbing layer and improves the uniformity of the light-absorbing layer's coverage over the recessed structure.

[0094] The light-absorbing layer may surround at least one of the object side, the image side, and the reflecting surface. This reduces the probability of non-imaging light being generated around the optical surface.

[0095] The optical transducer can have two connecting surfaces, which are arranged opposite to each other. Furthermore, it can have two recessed structures, each located on one of the two connecting surfaces. In other words, the optical transducer can include two connecting surfaces, respectively located on the object-side surface, the image-side surface, and the reflecting surface, and both connecting surfaces have recessed structures. This symmetrical design of the recessed structures helps to provide a more balanced release force, thus maintaining the optical quality of the optical transducer.

[0096] The two recessed structures can be interconnected to form a groove between them. This improves the structural strength of the optical switching element and reduces its weight.

[0097] The depth of the trench is Dg, and the distance between the top and bottom ends of the single concave structure is D, which satisfies the following condition: Dg / D ≤ 1. Therefore, the trench design maintains a high production yield. Please refer to... Figure 7 The diagram illustrates parameters Dg and D according to the first embodiment of the present invention.

[0098] The groove can be located between two of the object-side, image-side, and reflecting surfaces. This reduces residual internal stress in the optical reversing element while maintaining image quality. The optical reversing element can have multiple reflecting surfaces, and the groove can be located between two of these reflecting surfaces.

[0099] The number of recessed structures can be two, and both recessed structures are located on a single connecting surface and are positioned opposite each other, with the two top portions of the two recessed structures respectively adjacent to the two opposite edges of the single connecting surface. This reduces manufacturing tolerances, thereby providing higher dimensional accuracy.

[0100] The tapering directions of the two tapering sections of the two concave structures can be opposite to each other. This allows for the feasibility of upper and lower mold disassembly during the molding of the light-transmitting element, simplifies the complexity of the mold, and thus reduces the production cost of the product.

[0101] The two tapered sections of the two concave structures can be connected to each other. This ensures the structural integrity of the concave structures and reduces the probability of shrinkage deformation during the molding of the light-transmitting element.

[0102] The number of reflective surfaces can be at least two. This allows for the design of a suitable optical path configuration based on optical and structural requirements, achieving miniaturization. Please refer to [reference needed]. Figure 1 and Figure 5 The diagram illustrates a camera module according to a first embodiment of the present invention. The light-transforming element 13 in the first embodiment includes four reflective surfaces 133a, 133b, 133c, and 133d. The object-side surface 131 is coplanar with one of the reflective surfaces 133b, and the image-side surface 132 is coplanar with another reflective surface 133c.

[0103] The light-transforming element can be manufactured by injection molding, and the light-transforming element has at least one injection mark located on the bonding surface. This provides manufacturability of the plastic light-transforming element.

[0104] This invention provides a camera module comprising an imaging lens, the aforementioned light-deflecting element, and an electronic image sensor. The light-deflecting element is located on the object side or image side of the imaging lens, and the electronic image sensor is disposed on the imaging surface of the imaging lens. The electronic image sensor is used to receive imaging light and convert the imaging light into electronic image signals. This configuration is suitable for use in telephoto camera modules, meeting the requirement of a small camera module size while maintaining good image quality.

[0105] The various technical features of the present invention used in the light-transforming element of the camera module can be combined and configured to achieve the corresponding effects.

[0106] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.

[0109] In this embodiment, the camera module 10 includes an imaging lens 11, a light deflection element 13, and an electronic photosensitive element 15. The light deflection element 13 is located on the image side of the imaging lens 11, and the electronic photosensitive element 15 is disposed on the imaging surface of the imaging lens 11. The electronic photosensitive element 15 is used to receive imaging light L and convert the imaging light L into an electronic image signal.

[0110] The light-shifting element 13 includes an object-side surface 131, an image-side surface 132, four reflecting surfaces 133a, 133b, 133c, and 133d, and two connecting surfaces 134a and 134b. The imaging ray L entering the camera module 10 is incident on the object-side surface 131 and exits from the image-side surface 132, whereby the imaging ray L is imaged onto the imaging surface by the imaging lens 11. In this embodiment, the imaging ray L first passes through the imaging lens 11 and then through the light-shifting element 13.

[0111] Reflecting surfaces 133a, 133b, 133c, and 133d are used to reflect the imaging ray L passing through the object-side surface 131 to the image-side surface 132, wherein the imaging ray L passes through the object-side surface 131, reflecting surface 133a, reflecting surface 133b, reflecting surface 133c, reflecting surface 133d, and image-side surface 132 in sequence. Reflecting surface 133b is coplanar with the object-side surface 131 and faces opposite directions, and reflecting surface 133c is coplanar with the image-side surface 132 and faces opposite directions.

[0112] Connecting surfaces 134a and 134b connect the object side 131, the image side 132, and the reflecting surfaces 133a, 133b, 133c, and 133d. The two connecting surfaces 134a and 134b are arranged opposite each other, meaning they are respectively located on either side of the object side 131, the image side 132, and the reflecting surfaces 133a, 133b, 133c, and 133d.

[0113] The optical transition element 13 has eight recessed structures 135a, 135b, 135c, 135d, 135e, 135f, 135g, and 135h. Four of these recessed structures 135a, 135b, 135c, and 135d are located on the connecting surface 134a, while the other four recessed structures 135e, 135f, 135g, and 135h are located on the connecting surface 134b. Each of the recessed structures 135a, 135b, 135c, 135d, 135e, 135f, 135g, and 135h recesses from either the connecting surface 134a or the connecting surface 134b into the interior of the optical transition element 13. In this embodiment, the recessed structures 135a, 135b, 135c, 135d, 135e, 135f, 135g, and 135h are each formed as a trapezoid on the same plane as the connecting surface 134a or the connecting surface 134b.

[0114] The recessed structures 135a, 135b, 135c, 135d, 135e, 135f, 135g, and 135h each include a top portion 1351, a bottom portion 1353, and a tapered portion 1355 on the connecting surface 134a or 134b. The top portion 1351 is adjacent to the edge of the connecting surface 134a or 134b, the bottom portion 1353 is disposed opposite to the top portion 1351, and the tapered portion 1355 connects the top portion 1351 and the bottom portion 1353 and is located between the top portion 1351 and the bottom portion 1353. The tapered portion 1355 has two tapered edges 1356 located on the connecting surface 134a or the connecting surface 134b. The two tapered edges 1356 connect the top end portion 1351 and the bottom end portion 1353, and the width of the tapered portion 1355 tapers from the top end portion 1351 to the bottom end portion 1353. The recessed structures 135a, 135b, 135c, 135d, 135e, 135f, 135g, and 135h each have two inclined surfaces 1357, and the two inclined surfaces 1357 extend from the two tapered edges 1356 into the interior of the light-transmitting element 13.

[0115] The recessed structures 135b and 135f are interconnected and form a groove 1358a therebetween, with the groove 1358a located between the reflecting surfaces 133b and 133d. Furthermore, the recessed structures 135c and 135g are interconnected and form a groove 1358b therebetween, with the groove 1358b located between the reflecting surfaces 133a and 133c.
