     BACKGROUND 
     Technical Field 
     The present disclosure relates to an optical imaging lens assembly, an image capturing unit and an electronic device, more particularly to an optical imaging lens assembly and an image capturing unit applicable to an electronic device. 
     Description of Related Art 
     In recent years, with the popularity of electronic devices having camera functionalities, the demand of miniaturized optical systems has been increasing. As advanced semiconductor manufacturing technologies have reduced the pixel size of sensors, and compact optical systems have gradually evolved toward the field of higher megapixels, there is an increasing demand for compact optical systems featuring better image quality. 
     For various requirements, the specifications of a camera module are strictly demanded so that the camera module can be applied to different kinds of electronic devices, such as advanced driver assistance systems (ADAS), dashboard cameras, lane departure warning systems (LDWS), vehicle backup cameras, blind spot detection systems, multiple lens devices, intelligent electronic devices, wearable devices, digital cameras, drones, sport cameras, network surveillance devices, human-computer interaction systems and other electronic imaging devices. 
     In conventional camera modules, due to the limitation to the shape of lens surfaces and the material selection, it is difficult to reduce the size thereof as well as satisfy the requirements of a smooth lens shape, easier lens assembling and low sensitivity. Furthermore, the capability of functioning normally under different environmental conditions while providing high quality images is an important factor for design of the camera modules. Take the aforementioned automotive devices for example, the camera modules can be disposed on the front side, the lateral side or other positions of a car in order to detect the objects in the surrounding environment. The angle of view of the camera modules can be determined according to its proposed sensing distance, direction and range. Moreover, the images captured by camera modules are processed by software to determine the condition of the environment, thereby achieving self-driving or driver assistance. The camera modules can work with telecommunication devices, radars, automatic high beam systems, blind spot detectors, pedestrian detectors, intelligent brake systems, road sign recognition systems or global positioning system (GPS) so as to improve traffic safety and bring convenience to daily life. To keep the automotive devices properly functioning in various kinds of conditions, such as driving in high temperature variation environments or encountering impacts while driving on unpaved roads, the camera modules should be designed to have high heat resistance, high corrosion resistance and high mechanical strength. 
     Therefore, there is a need to develop an optical system featuring wide field of view, compact size, high image quality and high resistance to environmental change.

     The first lens element can have an image-side surface being concave in a paraxial region thereof. Therefore, it is favorable for providing the optical imaging lens assembly with a retro-focus configuration for gathering light from large angle of view. 
     The second lens element has negative refractive power; therefore, it is favorable for balancing the refractive power distribution between the first lens element and the second lens element so as to gather light from large angle of view, and thereby broaden the field of view, such that the optical imaging lens assembly is applicable to more kinds of applications. The second lens element can have an object-side surface being convex in a paraxial region thereof; therefore, it is favorable for providing the optical imaging lens assembly with a wide-angle lens configuration so as to broaden the field of view. The second lens element can have an image-side surface being concave in a paraxial region thereof; therefore, it is favorable for correcting aberrations generated due to an overly large incident angle. 
     The third lens element can have positive refractive power; therefore, it is favorable for balancing the negative refractive power on the object side of the optical imaging lens assembly, so that light rays with large angle of view are properly refracted and propagated in the optical imaging lens assembly. The third lens element can have an image-side surface being convex in a paraxial region thereof; therefore, it is favorable for moderating the incident light rays with large angle of view and correcting aberrations on the object side of the optical imaging lens assembly. 
     The fourth lens element can have positive refractive power; therefore, it is favorable for balancing the negative refractive power on the object side of the optical imaging lens assembly, moderating the incident light with large angle of view, reducing sensitivity, and enhancing light convergence capability so as to reduce a total track length of the optical imaging lens assembly, thereby meeting the requirement of compactness. The fourth lens element can have an object-side surface being convex in a paraxial region thereof; therefore, it is favorable for correcting spherical aberration so as to improve the image quality. The fourth lens element can have an image-side surface being convex in a paraxial region thereof; therefore, it is favorable for keeping sufficient refractive power of the fourth lens element so as to reduce sensitivity. 
     The fifth lens element has negative refractive power; therefore, it is favorable for correcting chromatic aberration on the image side of the optical imaging lens assembly so as to improve the image quality. The fifth lens element can have an image-side surface being concave in a paraxial region thereof; therefore, it is favorable for correcting chromatic aberration to improve the image quality. 
     The sixth lens element has positive refractive power; therefore, it is favorable for the sixth lens element to work with the fifth lens element to correct off-axis aberrations and alleviate the influence of environmental temperature change on a back focal length of the optical imaging lens assembly, thereby reducing sensitivity and improving the image quality. The sixth lens element can have an object-side surface being convex in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof; therefore, it is favorable for reducing the angle of light rays incident in the image surface in the off-axis region so as to provide high illuminance and correct off-axis aberrations. 
     At least one of the image-side surface of the fifth lens element and the object-side surface of the sixth lens element can have at least one inflection point. Therefore, it is favorable for peripheral light rays being received by the image surface, thereby preventing stray light, which is generated due to an overly large incident angle, from degrading the image quality; furthermore, it is favorable for reducing the angle of light rays incident in the image surface in the off-axis region so as to provide high illuminance and further improve the image quality. 
     When a curvature radius of an object-side surface of the fifth lens element is R9, and a curvature radius of the image-side surface of the fifth lens element is R10, the following condition is satisfied: 0.0&lt;(R9+R10)/(R9−R10). Therefore, adjusting a shape of the fifth lens element is favorable for correcting off-axis aberrations on the image side of the optical imaging lens assembly so as to increase image brightness and improve the image quality. Preferably, the following condition can be satisfied: 0.60&lt;(R9+R10)/(R9−R10). More preferably, the following condition can also be satisfied: 0.65&lt;(R9+R10)/(R9−R10)&lt;2.50. When a focal length of the optical imaging lens assembly is f, and an entrance pupil diameter of the optical imaging lens assembly is EPD, the following condition is satisfied: f/EPD&lt;3.50. Therefore, it is favorable for gathering sufficient amount of incident light to increase illuminance on the image surface, so that an imaging capturing unit including the optical imaging lens assembly is able to capture enough image information in low light condition (for example, in the night) or short exposure photography (for example, dynamic photography), and thus an electronic device equipped with the imaging capturing unit is able to work under various conditions. Preferably, the following condition can be satisfied: f/EPD&lt;2.80. More preferably, the following condition can also be satisfied: 0.50&lt;f/EPD&lt;2.50.

Preferably, the following condition can also be satisfied: 0.10&lt;|f5/CT3|&lt;1.50. 
     When a focal length of the sixth lens element is f6, and a central thickness of the sixth lens element is CT6, the following condition can be satisfied: |f6/CT6|&lt;0.90. Therefore, it is favorable for the sixth lens element to have sufficient positive refractive power to correct off-axis aberrations on the image side of the optical imaging lens assembly, and reducing the total track length of the optical imaging lens assembly so as to achieve compactness for various applications. Preferably, the following condition can be satisfied: |f6/CT6|&lt;0.80. More preferably, the following condition can be satisfied: |f6/CT6|&lt;0.70. Much more preferably, the following condition can also be satisfied: 0.10&lt;|f6/CT6|&lt;0.65. 
     When an Abbe number of the fourth lens element is V4, and an Abbe number of the fifth lens element is V5, the following condition can be satisfied: V4−V5&lt;29.0. Therefore, selecting proper materials of the fourth lens element and the fifth lens element is favorable for reducing the sensitivity to the temperature variation among different environments, and correcting chromatic aberration so as to improve the image quality. Preferably, the following condition can be satisfied: V4−V5&lt;27.0. More preferably, the following condition can also be satisfied: 1.0&lt;V4−V5&lt;25.0. 
     When an axial distance between the image-side surface of the sixth lens element and an image surface is BL, and the central thickness of the third lens element is CT3, the following condition can be satisfied: BL/CT3&lt;1.0. Therefore, keeping a proper ratio of the back focal length to the central thickness of the third lens element is favorable for reducing the back focal length and propagating light with large angle of view in the optical imaging lens assembly, thereby obtaining a balance among low sensitivity, compactness and high illuminance. 
     When the central thickness of the third lens element is CT3, and a central thickness of the fourth lens element is CT4, the following condition can be satisfied: CT4/CT3&lt;1.0. Therefore, maintaining a proper ratio of the central thickness of the fourth lens element to the central thickness of the third lens element is favorable for gathering light from large angle of view and increasing the stability of the optical imaging lens assembly. Preferably, the following condition can also be satisfied: 0.10&lt;CT4/CT3&lt;0.70. 
     When half of a maximum field of view of the optical imaging lens assembly is HFOV, the following condition can be satisfied: 1/|tan(HFOV)|&lt;0.35. Therefore, it is favorable for increasing the field of view for more applications. 
     When a central thickness of the first lens element is CT1, and the central thickness of the third lens element is CT3, the following condition can be satisfied: 0.10&lt;CT1/CT3&lt;0.65. Therefore, keeping a proper ratio of the central thickness of the first lens element to the central thickness of the third lens element is favorable for properly refracting light rays with large angle of view so as to reduce sensitivity. Preferably, the following condition can also be satisfied: 0.20&lt;CT1/CT3&lt;0.65.

Therefore, properly arranging the refractive power of the six lens elements to obtain the wide-angle lens configuration is favorable for increasing the imaging range for various applications. According to the present disclosure, a refractive power of a single lens element is a ratio of the focal length of the optical imaging lens assembly to the focal length of the single lens element. 
     When the focal length of the fifth lens element is f5, the central thickness of the third lens element is CT3, and the central thickness of the sixth lens element is CT6, the following condition can be satisfied: |f5/CT6|+|f5/CT3|&lt;2.0. Therefore, it is favorable for obtaining good space utilization so as to obtain a balance among compactness, low sensitivity and high manufacturing yield rate. Preferably, the following condition can also be satisfied: 0.10&lt;|f5/CT6|+|f5/CT3|&lt;1.45. 
     When a focal length of the first lens element is f1, a focal length of the second lens element is f2, and a focal length of the third lens element is f3, the following conditions can be satisfied: |f2|&lt;|f1|; and |f2|&lt;|f3|. Therefore, properly arranging the refractive power of the lens elements on the object side of the optical imaging lens assembly is favorable for obtaining the wide-angle lens configuration so as to broaden the field of view, such that the optical imaging lens assembly is applicable to more kinds of applications. 
     When an Abbe number of the third lens element is V3, the Abbe number of the fourth lens element is V4, and the Abbe number of the fifth lens element is V5, the following condition can be satisfied: 30&lt;V3+V4+V5&lt;105. Therefore, the materials of the third, the fourth and the fifth lens elements are properly selected so as to prevent f-theta (f-θ) distortion due to the optical imaging lens assembly having wide field of view, thereby preventing image distortion and increasing image resolution. 
     When a central thickness of the fifth lens element is CT5, and the central thickness of the sixth lens element is CT6, the following condition can be satisfied: 0.50&lt;CT6/CT5&lt;5.0. Therefore, controlling a ratio of the central thickness of the sixth lens element to the central thickness of the fifth lens element is favorable for balancing the space arrangement of the optical imaging lens assembly, thereby ensuring high image quality. Preferably, the following condition can also be satisfied: 1.0&lt;CT6/CT5&lt;3.75. 
     When a curvature radius of the object-side surface of the sixth lens element is R11, and a curvature radius of the image-side surface of the sixth lens element is R12, the following condition can be satisfied: |R11/R12|&lt;0.50. Therefore, in cooperation with the fifth lens element, a shape of the sixth lens element is favorable for correcting off-axis aberrations, and preventing stray light generated on the image side of the optical imaging lens assembly so as to increase illuminance on the image surface and improve the image quality. Preferably, the following condition can also be satisfied: |R11/R12|&lt;0.45. 
     According to the present disclosure, the optical imaging lens assembly further includes an aperture stop.

Therefore, controlling the position of the aperture stop is favorable for simultaneously increasing image-sensing efficiency of the image sensor and maintaining sufficient field of view. 
     According to the present disclosure, both the image-side surface of the fifth lens element and the object-side surface of the sixth lens element can be aspheric, and the fifth lens element and the sixth lens element can be cemented to each other. When a refractive index of the fifth lens element is N5, and a refractive index of the sixth lens element is N6, the following condition can be satisfied: 3.0&lt;N5+N6&lt;3.30. Therefore, selecting proper materials of the fifth and the sixth lens elements is favorable for minimizing manufacturing cost and reducing the total track length; furthermore, the fifth lens element and the sixth lens element being cemented to each other on their aspheric surfaces is favorable for reducing the impact of temperature variation on the optical imaging lens assembly and correcting off-axis aberrations. 
     When a displacement in parallel with an optical axis from an axial vertex of the image-side surface of the fifth lens element to a maximum effective radius position of the image-side surface of the fifth lens element is SAG52, and a displacement in parallel with the optical axis from an axial vertex of the object-side surface of the sixth lens element to a maximum effective radius position of the object-side surface of the sixth lens element is SAG61, the following condition can be satisfied: SAG52&lt;SAG61. Therefore, adjusting the shapes of the image-side surface of the fifth lens element and the object-side surface of the sixth lens element is favorable for enhancing the shape design flexibility of the lens surfaces and correcting off-axis aberrations. Please refer to  FIG. 23 , which shows a schematic view of SAG52 and SAG61 according to the 1st embodiment of the present disclosure. When the direction from the axial vertex of one surface to the maximum effective radius position of the same surface is facing towards the image side of the optical imaging lens assembly, the value of SAG52 or SAG61 is positive; when the direction from the axial vertex of the surface to the maximum effective radius position of the same surface is facing towards the object side of the optical imaging lens assembly, the value of SAG52 or SAG61 is negative. 
     When a curvature radius of an object-side surface of the third lens element is R5, and a curvature radius of the image-side surface of the third lens element is R6, the following condition can be satisfied: |R6/R5|&lt;1.50. Therefore, adjusting a shape of the third lens element is favorable for correcting aberrations generated by large incident angle and reducing sensitivity. 
     According to the present disclosure, at least three of the six lens elements of the optical imaging lens assembly can be made of plastic material, and all object-side surfaces and image-side surfaces of the at least three lens elements can be aspheric. Therefore, the materials of the lens elements are properly selected so as to reduce manufacturing cost; furthermore, the aspheric surfaces are favorable for meeting the requirement of compactness and improving the image quality. 
     According to the present disclosure, when the fifth lens element and the sixth lens element are cemented to each other, a central thickness of an adhesive layer between the image-side surface of the fifth lens element and the object-side surface of the sixth lens element is D, and the following condition can be satisfied: 0.02 [mm]≤D&lt;0.05 [mm]. Therefore, a proper thickness of the adhesive layer is favorable for maintaining a good manufacturing yield rate; furthermore, the fifth lens element and the sixth lens element being cemented to each other on their aspheric surfaces is favorable for reducing the impact of temperature variation on the optical imaging lens assembly and correcting off-axis aberrations. Please refer to  FIG. 24 , which shows an adhesive layer AL between an image-side surface  152  of a fifth lens element  150  and an object-side surface  161  of a sixth lens element  160 , and the central thickness D of the adhesive layer AL, according to the 1st embodiment of the present disclosure. 
     According to the present disclosure, an absolute value of the curvature radius of the image-side surface of the fifth lens element and an absolute value of the curvature radius of the object-side surface of the sixth lens element are both smaller than the absolute values of the curvature radii of the other lens surfaces of the six lens elements. That is, both the image-side surface of the fifth lens element and the object-side surface of the sixth lens element have smaller absolute value of curvature radius than the object-side surfaces and the image-side surfaces of the first through the fourth lens elements, the object-side surface of the fifth lens element, and the image-side surface of the sixth lens element. Therefore, a proper arrangement of the curvature radii of the lens surfaces of the six lens elements is favorable for correcting off-axis aberrations, increasing illuminance on the image surface and improving the image quality. 
     When the displacement in parallel with the optical axis from the axial vertex of the image-side surface of the fifth lens element to the maximum effective radius position of the image-side surface of the fifth lens element is SAG52, and the displacement in parallel with the optical axis from the axial vertex of the object-side surface of the sixth lens element to the maximum effective radius position of the object-side surface of the sixth lens element is SAG61, the following condition can be satisfied: 0.03 [mm]&lt;|SAG52−SAG61|×100. Therefore, adjusting the shapes of the image-side surface of the fifth lens element and the object-side surface of the sixth lens element is favorable for enhancing the shape design flexibility of the lens surfaces and correcting off-axis aberrations. Preferably, the following condition can also be satisfied: 0.05 [mm]&lt;|SAG52−SAG61|×100&lt;6.0 [mm]. 
     When a refractive index of the first lens element is N1, and a refractive index of the fourth lens element is N4, the following condition can be satisfied: 1.70≤(N1+N4)/2&lt;2.80. Therefore, selecting proper materials of the first lens element and the fourth lens element is favorable for the optical imaging lens assembly to be applicable to different environmental conditions, so the optical imaging lens assembly is capable of functioning normally under different environmental conditions, such as environments having different temperature and humidity, while providing high quality images. 
     According to the present disclosure, the aforementioned features and conditions can be utilized in numerous combinations so as to achieve corresponding effects. 
     According to the present disclosure, the lens elements thereof can be made of glass or plastic material. When the lens elements are made of glass material, the distribution of the refractive power of the optical imaging lens assembly may be more flexible to design. When the lens elements are made of plastic material, the manufacturing cost can be effectively reduced. Furthermore, surfaces of each lens element can be arranged to be aspheric, since the aspheric surface of the lens element is easy to form a shape other than spherical surface so as to have more controllable variables for eliminating the aberration thereof, and to further decrease the required number of the lens elements. Therefore, the total track length of the optical imaging lens assembly can also be reduced. 
     According to the present disclosure, when a lens surface is aspheric, it means that the lens surface has an aspheric shape throughout its optically effective area, or a portion(s) thereof. 
     According to the present disclosure, each of an object-side surface and an image-side surface has a paraxial region and an off-axis region. The paraxial region refers to the region of the surface where light rays travel close to the optical axis, and the off-axis region refers to the region of the surface away from the paraxial region. Particularly, unless otherwise stated, when the lens element has a convex surface, it indicates that the surface is convex in the paraxial region thereof; when the lens element has a concave surface, it indicates that the surface is concave in the paraxial region thereof. Moreover, when a region of refractive power or focus of a lens element is not defined, it indicates that the region of refractive power or focus of the lens element is in the paraxial region thereof. 
     According to the present disclosure, an inflection point is a point on the surface of the lens element at which the surface changes from concave to convex, or vice versa. 
     According to the present disclosure, an image surface of the optical imaging lens assembly, based on the corresponding image sensor, can be flat or curved, especially a curved surface being concave facing towards the object side of the optical imaging lens assembly. 
     According to the present disclosure, an image correction unit, such as a field flattener, can be optionally disposed between the lens element closest to the image side of the optical imaging lens assembly and the image surface for correction of aberrations such as field curvature. The optical properties of the image correction unit, such as curvature, thickness, index of refraction, position and surface shape (convex or concave surface with spherical, aspheric, diffractive or Fresnel types), can be adjusted according to the demand of an image capturing unit. In general, a preferable image correction unit is, for example, a thin transparent element having a concave object-side surface and a planar image-side surface, and the thin transparent element is disposed near the image surface. 
     According to the present disclosure, the optical imaging lens assembly can include at least one stop, such as an aperture stop, a glare stop or a field stop. Said glare stop or said field stop is set for eliminating the stray light and thereby improving the image quality thereof. 
     According to the present disclosure, an aperture stop can be configured as a front stop or a middle stop. A front stop disposed between an imaged object and the first lens element can provide a longer distance between an exit pupil of the optical imaging lens assembly and the image surface to produce a telecentric effect, and thereby improves the image-sensing efficiency of an image sensor (for example, CCD or CMOS). A middle stop disposed between the first lens element and the image surface is favorable for enlarging the viewing angle of the optical imaging lens assembly and thereby provides a wider field of view for the same. 
     According to the present disclosure, an image capturing unit includes the aforementioned optical imaging lens assembly and an image sensor, wherein the image sensor is disposed on the image surface of the optical imaging lens assembly. In some embodiments, the image capturing unit can further include a barrel, a holder member or a combination thereof. 
     According to the present disclosure, the aforementioned image capturing unit may be installed in, but not limited to, an electronic device. Please refer to  FIG. 25 ,  FIG. 26  and  FIG. 27 , an image capturing unit  10  can be applied to electronic devices, such as a vehicle backup camera ( FIG. 25 ), a network surveillance device ( FIG. 26 ) or a dashboard camera ( FIG. 27 ). In some embodiments, the electronic device can further include, but not limited to, a control unit, a display unit, a storage unit, a random access memory unit (RAM), a read only memory unit (ROM) or a combination thereof. 
     According to the present disclosure, the optical imaging lens assembly can be optionally applied to optical systems with a movable focus. Furthermore, the optical imaging lens assembly features good capability in aberration corrections and high image quality, and can be applied to 3D (three-dimensional) image capturing applications, in products, such as advanced driver assistance systems (ADAS), lane departure warning systems (LDWS), blind spot detection systems, multiple lens devices, smart phones, smart televisions, digital cameras, drones, sport cameras, mobile devices, digital tablets, network surveillance devices, motion sensing input devices, wearable devices and other electronic imaging devices. The aforementioned electronic devices are only exemplary for showing the image capturing unit of the present disclosure installed in an electronic device and are not limited thereto.

     In Table 1, the curvature radius, the thickness and the focal length are shown in millimeters (mm). Surface numbers 0-18 represent the surfaces sequentially arranged from the object side to the image side along the optical axis. In Table 2, k represents the conic coefficient of the equation of the aspheric surface profiles. A4-A12 represent the aspheric coefficients ranging from the 4th order to the 12th order. The tables presented below for each embodiment are the corresponding schematic parameter and aberration curves, and the definitions of the tables are the same as Table 1 and Table 2 of the 1st embodiment. Therefore, an explanation in this regard will not be provided again.
