Description
Technical Field
The present invention relates to an optical device, and more particularly, to an electrochromic lens module.
Background
A conventional vehicle includes a rear-view mirror (rear-view mirror) made of electrochromic (electrochromic) material. In the existing electrochromic rearview mirror device, an electrochromic material can provide a reflection picture with higher brightness in the daytime so as to observe a rear vehicle, and increase the light absorption rate at night so as to provide a function of preventing glare, so that the influence of the lamp of the rear vehicle on the driving vision is avoided.
However, in order to operate the above functions, the conventional electrochromic rearview mirror device is provided with a switch and an adjusting button on the lower edge of the rearview mirror device, for example, which makes the operation difficult. In addition, the electrochromic rearview mirror device arranges a switch and an adjusting button on the mirror surface of the rearview mirror, so that the driving of the vehicle behind the vehicle can be influenced by the operation process. Therefore, how to provide an electrochromic rearview mirror with a proper operation interface is one of the problems to be solved by those skilled in the art.
Meanwhile, the electrochromic material may also be made into a rear view mirror (also called a side view mirror), and the rear view mirror may be disposed at both sides of the outside of the vehicle. However, how to further increase the auxiliary function of such a rear-view mirror is also one of the problems to be solved by those skilled in the art.

Fig. 1 is a schematic perspective view of an electrochromic lens module according to an embodiment of the invention. Referring to fig. 1, an electrochromic lens module 100 according to an embodiment of the present invention provides a visible surface 101 through which a driver can view a rear scene, and the electrochromic lens module 100 can be mounted in a vehicle. For example, the electrochromic lens module 100 of the present embodiment may include the connection end 102, and the electrochromic lens module 100 may be mounted on a windshield of a vehicle through the connection end 102, but the present invention is not limited thereto.
In the embodiment, the connecting end 102 may be adhered to the windshield by an adhesive, or a bump may be additionally disposed to engage with a fixing groove on the windshield. The connection end 102 may include, for example, a rotation shaft, which may be located at a side connected to the windshield or at a side connected to the electrochromic lens module 100, and the rotation shaft may be, for example, a spherical rotation shaft, but the present invention is not limited thereto. On the other hand, the present invention is not limited to the shape and number of the connection terminals 102, and one skilled in the art can adjust the number and shape of the connection terminals 102 according to the requirement so that the electrochromic lens module 100 can be properly connected to the windshield of the vehicle.
On the other hand, referring to fig. 1, the electrochromic lens module 100 of the present embodiment may include a housing 103, for example. The housing 103 of the present embodiment may, for example, enclose a portion of the electrochromic lens module 100 behind the viewing surface 101. For example, the electrochromic lens module 100 of the present embodiment can provide a frameless visible surface 101, but the invention is not limited thereto. In other embodiments, the electrochromic lens module 100 may also provide the viewing surface 101 with a frame. The material of the housing 103 may be, for example, acryl with high hardness or other materials suitable for providing a supporting effect, but the invention is not limited thereto. The present invention is not limited to the shape, size and connection manner of the connection end 102 and the housing 103, and the detailed elements of the electrochromic lens module 100 in the embodiment will be described in further detail below.
Fig. 2 is a schematic cross-sectional view according to section line I of fig. 1. In the drawings, the size and thickness of layers, films, panels, regions, etc. have been exaggerated for clarity. Throughout the specification, the same or similar reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected" to another element, there are no intervening elements present. As used herein, "connected" may refer to physical and/or electrical connections. Further, an "electrical connection" or "coupling" may be the presence of other elements between the two elements.
Referring to fig. 2, in the present embodiment, the electrochromic lens module 100 includes a first transparent substrate 110, an opaque touch sensing layer 120, and an electrochromic device 130. The first transparent substrate 110 has a visible surface 101 and a back surface 111 opposite to the visible surface 101. The opaque touch sensing layer 120 and the electrochromic device 130 are disposed on the back surface 111 of the first transparent substrate 110. The opaque touch sensing layer 120 and the electrochromic device 130 are disposed at different positions on the back surface 111.
For example, the opaque touch sensing layer 120 is disposed at the periphery of the viewing surface 101 at the back 111, and the remaining portion of the viewing surface 101 corresponds to the electrochromic device 130. In other embodiments of the present invention, the position of the opaque touch sensing layer 120 disposed on the back surface 111 and the position of the electrochromic device 130 corresponding to the back surface 111 may partially overlap, so that the visible surface 101 corresponding to the electrochromic device 130 may also have a touch sensing function.
On the other hand, referring to fig. 1, in other embodiments of the invention, the distribution position of the opaque touch sensing layer 120 on the back surface 111 may be adjacent to one of the side edges (i.e., the top edge L1, the bottom edge L2, the side edge L3, and the side edge L4) of the visible surface 101.
The periphery of the viewing surface 101 is, for example, the area adjacent to the edge or corner of the periphery of the viewing surface 101, and the electrochromic element 130 can provide a high brightness reflective image or a low brightness reflective image.
Referring to fig. 2, the electrochromic lens module 100 of the present embodiment can be used as a rear view mirror on a vehicle, and the electrochromic lens module 100 can simultaneously provide a touch operation function around the visible surface 101 through the opaque touch sensing layer 120, so that a driver can control the electrochromic device 130 or other devices around the visible surface 101. At the same time, the driver may view the rear vehicle at other locations on the viewing surface 101 via the electrochromic element 130.
For example, the visible surface 101 of the electrochromic lens module 100 of the embodiment may be a plane, but the invention is not limited thereto. In other embodiments, the viewing surface 101 of the electrochromic lens module 100 may be planar, curved. In other embodiments of the present invention, the viewing surface 101 of the electrochromic lens module 100 may be a 2.5D surface. On the other hand, the shape of the visible surface 101 is rectangular in the above-described embodiment, but the present invention is not limited thereto. In other embodiments of the present invention, the shape of the viewing surface 101 of the electrochromic lens module 100 may be circular or elliptical or other polygonal shape. On the other hand, the periphery of the visible surface 101 forms a right angle in the above embodiments, but the invention is not limited thereto. In other embodiments, the perimeter of the viewing surface 101 may form a right angle, a rounded corner (corner r), or a 2.5D corner.
In other words, referring to fig. 2, the visible surface 101 of the present embodiment has an observation area a and an operation area B. The operation area B is distributed around the visible surface 101, and the observation area a is distributed in the middle of the visible surface 101. In the present embodiment, the area of the opaque touch sensing layer 120 projected onto the visible surface 101 is located in the operation area B, and the area of the electrochromic device 130 projected onto the visible surface 101 at least covers the observation area a. The viewing area a and the operating area B on the viewing surface 101 of the electrochromic lens module 100 of the present embodiment do not overlap with each other, and therefore the viewing area a is not shielded when the driver operates in the operating area B, and the driving safety can be further ensured.
On the other hand, since the visible surface 101 on the first transparent substrate 110 of the embodiment can provide the functions of observation and operation at the same time, the housing 103 of the electrochromic lens module 100 can be connected to the back surface 111 of the first transparent substrate 110, so that the electrochromic lens module 100 can provide a frameless visible surface 101, thereby improving the driving visual experience. The invention is not limited in this regard and in other embodiments the housing 103 may have sidewalls that may surround the perimeter of the first light transmissive substrate 110 and the sidewalls may have a front face that is flush with the viewing surface 101 such that the surface of the electrochromic lens module 100 facing the driver may be presented in a full-planar manner.
In detail, referring to fig. 1, the visible surface 101 of the present embodiment may be a rectangle, and includes a top side L1, a bottom side L2, and two side sides L3 and L4. The length of the top edge L1 and the bottom edge L2 is longer than the length of the side edges L3 and L4. Referring to fig. 2 again, in the present embodiment, the distribution positions of the opaque touch sensing layer 120 on the back surface 111 correspond to the positions of the visible surface 101 near the bottom edge L2.
In other words, in the embodiment, when the driver views the visible surface 101, the corresponding position of the opaque touch sensing layer 120 is located at the lower edge of the visible surface 101, so that the driver does not hide the area of the visible surface 101 corresponding to the electrochromic device 130 during the operation.
For example, in the embodiment, the width W1 of the position of the opaque touch sensing layer 120 corresponding to the visible surface 101 and perpendicular to the bottom edge L2 may be 6 millimeters (mm), but the invention is not limited thereto. In other embodiments, the width W1 of the opaque touch sensing layer 120 corresponding to the visible surface 101 at a position perpendicular to the bottom edge L2 may be 6 mm to 10 mm, and the width W1 may be further increased according to requirements. Therefore, the opaque touch sensing layer 120 can provide a good sensing area without occupying an excessively large area on the viewing surface 101.
On the other hand, the material of the first transparent substrate 110 may include glass, for example, but the invention is not limited thereto. In other embodiments, the material of the first transparent substrate 110 may further include transparent acryl or other transparent materials, and the material of the first transparent substrate 110 may also be a material that absorbs light of a specific spectrum, which is not limited herein.
On the other hand, in the present embodiment, the opaque touch sensing layer 120 forms a capacitor on the first transparent substrate 110, so that a sensing signal can be generated when a driver touches the visible surface 101. For example, the electrochromic lens module 100 of the present embodiment may include a processing unit, the processing unit is electrically connected to the opaque touch sensing layer 120, and the opaque touch sensing layer 120 may generate and process a position sensing signal corresponding to a driving contact by self-capacitive sensing or mutual capacitive sensing, for example, but the invention is not limited thereto.
Referring to fig. 2, in the present embodiment, the opaque touch sensing layer 120 may include a patterned metal electrode 121, and the patterned metal electrode 121 is disposed on the back surface 111 of the first transparent substrate 110, wherein the patterned metal electrode 121 has a hollow area C, and a plurality of electrode patterns 122 to 127 may be formed by the shape of the hollow area C. Referring to fig. 1, in the present embodiment, a plurality of electrode patterns 122-127 may be formed on the patterned metal electrode 121, wherein the electrode pattern 127 corresponds to a power source of the electrochromic device 130, the electrode pattern 126 corresponds to a guiding function of a vehicle, the electrode pattern 125 corresponds to a wireless transmission function, the electrode pattern 124 corresponds to a hands-free function, the electrode pattern 123 corresponds to a brightness adjustment function, and the electrode pattern 122 corresponds to a reset function. In other words, the electrochromic lens module 100 of the present embodiment can be further electrically connected to a control unit of the vehicle, and control a mobile phone, a wireless transmission module or a Global Positioning System (GPS) module in the vehicle by the touch function of the opaque touch sensing layer 120. That is to say, the electrochromic lens module 100 of the present embodiment not only allows the driving control of the electrochromic device 130 through the opaque touch sensing layer 120, but also provides an additional interface to control other functions of the vehicle.
On the other hand, the opaque touch sensing layer 120 of the embodiment of the invention can provide an easy and low-cost manufacturing method. The patterned metal electrode 121 and the connecting lines thereof of the present embodiment are plated on the back surface 111 of the first transparent substrate 110. For example, the patterned metal electrode 121 and the connecting circuit thereof of the present embodiment are fabricated on the back surface 111 of the first transparent substrate 110 by a photolithography process. The patterned metal electrode 121 is formed on the back surface 111 of the first transparent substrate 110 by, for example, physical vapor deposition or chemical vapor deposition, and then patterned by using a mask, photolithography, and the like, so that the metal layer is partially hollowed out to form a hollow area C. In other embodiments of the present invention, the hollow area C may further divide and cut the metal electrode into discrete touch-controllable operation areas, and simultaneously form a patterned pattern corresponding to each touch-controllable operation area to complete a corresponding button, and also complete a connection circuit of each button.
In other words, the buttons and the circuit in the opaque touch sensing layer 120 are completed simultaneously by one photomask. Therefore, the opaque touch sensing layer 120 of the present embodiment not only can provide a good operation interface, but also can be formed in a low-cost manner, thereby reducing the manufacturing cost of the entire electrochromic lens module 100. On the other hand, the opaque touch sensing layer 120 can be easily changed in size, width and position by the above manufacturing method, thereby providing a good customized function.
In detail, in the present embodiment, the material of the patterned metal electrode 121 may include aluminum, but the present invention is not limited thereto. In other embodiments, the material of the patterned metal electrode 121 may include a conductive material or a plating material. The coating material may include an alloy material composed of at least one or more of silver, molybdenum, copper, gold, titanium, platinum, nickel, or chromium. The patterned metal electrode 121 may be disposed on the back surface 111 of the first transparent substrate 110 by plating, printing, attaching or coating.
On the other hand, since the opaque touch sensing layer 120 is made of a reflective material, the visible surface 101 can be formed as a full mirror.
Referring to fig. 1, in the embodiment, the electrode patterns 122 to 127 are arranged on the bottom side L2 of the visible surface 101, but the invention is not limited thereto. In other embodiments, the electrode patterns 122-127 can be further arranged on the top edge L1 of the viewing surface 101.
On the other hand, referring to fig. 2, in the present embodiment, the electrochromic lens module 100 further includes an adhesive layer 140. The adhesive layer 140 and the opaque touch sensing layer 120 are disposed between the first transparent substrate 110 and the electrochromic device 130, so that the electrochromic device 130 can be adhered to the first transparent substrate 110.
On the other hand, in the present embodiment, the electrochromic element 130 includes a first control electrode 132, an electrochromic layer 133, and a second control electrode 134. The electrochromic layer 133 is disposed between the first control electrode 132 and the second control electrode 134, and a distance between the first control electrode 132 and the first transparent substrate 110 is smaller than a distance between the second control electrode 134 and the first transparent substrate 110.
For example, the material of the first control electrode 132 and the second control electrode 134 in the present embodiment includes a light-transmitting conductive material, for example. The light-transmitting conductive material may include indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, titanium oxide, or a stacked layer of at least two of the foregoing, and the present invention is not limited thereto. In other words, the material of the first control electrode 132 and the second control electrode 134 includes at least one material selected from the group consisting of indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, and fluorine-doped tin oxide.
The electrochromic lens module 100 applies a voltage to the first control electrode 132 and the second control electrode 134 to apply an electric field to the electrochromic layer 133. The electrochromic layer 133 includes an electrochromic material, and optical properties (reflectivity, transmittance, absorption, etc.) of the electrochromic material may be stably and reversibly changed by an electric field. Accordingly, the first and second control electrodes 132 and 134 may control the optical properties of the electrochromic layer 133. Further, in the present embodiment, the reflectivity of the electrochromic lens module 100 to the incident light i1 is greater than 40%.
Further, in the present embodiment, the transmittance of the electrochromic layer 133 to incident light is greater than 15%.
For example, the electrochromic layer 133 of the present embodiment is an organic material. The organic material is, for example, a high molecular polymer of ethylenedioxythiophene monomer (EDOT) or william monomer (Viologen) or acryl monomer (PMMA). In other embodiments of the present invention, the electrochromic layer 133 is a self-luminous material.
On the other hand, the material of the first control electrode 132 and the second control electrode 134 may include at least one selected from the group consisting of indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, titanium oxide, indium germanium zinc oxide, and fluorine-doped tin oxide, or a composite material of at least two.
Still further, in the present embodiment, the electrochromic device 130 further includes a second transparent substrate 131 and a reflective substrate 135, and the reflective substrate 135 is opposite to the second transparent substrate 131. The distance between the second transparent substrate 131 and the viewing surface 101 of the present embodiment is smaller than the distance between the reflective substrate 135 and the viewing surface 101. The first control electrode 132 is disposed on the surface of the second light-transmitting substrate 131 facing the electrochromic layer 133, and the second control electrode 134 is disposed on the surface of the reflective substrate 135 facing the electrochromic layer 133. The incident light i1 may penetrate through the second light-transmitting substrate 131 to reach the electrochromic layer 133, and the light passing through the electrochromic layer 133 may be reflected by the reflective substrate 135, so that the electrochromic element 130 may provide the reflected light i 2.
For example, in the present embodiment, the second transparent substrate 131 is, for example, a glass substrate, and the reflective substrate 135 is, for example, a metal or non-metal substrate, or a glass substrate plated with a metal surface to provide a reflective surface. In other embodiments, a reflective layer may also be formed on the reflective substrate 135, and the material of the reflective layer may include a plating material. The coating material may include at least one of silver, copper, aluminum, titanium, molybdenum, etc., or an alloy material composed of a plurality of these materials. The present invention is not limited to the material of the reflective substrate 135.
For another example, when the vehicle is driven in the daytime, the electrochromic layer 133 can reduce the absorption rate or increase the transmittance by the electric field generated by the first control electrode 132 and the second control electrode 134, so as to increase the intensity of the reflected light i2, thereby allowing the user to clearly observe the scene behind the vehicle. When the vehicle is driven in a dark environment, the electrochromic layer 133 can increase the absorption rate or decrease the transmittance by the electric field generated by the first control electrode 132 and the second control electrode 134, so that the brightness of the reflected light i2 is decreased, and the occurrence of glare caused by the lamps behind the vehicle and the resulting disturbance, discomfort or impaired vision of the user is avoided.
On the other hand, referring to fig. 2, in the present embodiment, the electrochromic lens module 100 may further include a carrier substrate 150, and the electrochromic device 130, the opaque touch sensing layer 120 and the first transparent substrate 110 are sequentially disposed on the carrier substrate 150 along the direction d 1.
In detail, the carrier substrate 150 of the present embodiment may be, for example, a glass substrate or a metal substrate to provide a proper supporting effect, but the invention is not limited thereto.
In another embodiment of the present invention, the electrochromic lens module may further include a color fill layer. Fig. 3 is a schematic cross-sectional view of an electrochromic lens module according to another embodiment of the invention. Referring to fig. 3, the electrochromic lens module 100A of the present embodiment is substantially similar to the electrochromic lens module 100 described above, and the same elements and connection relationships are not described herein again, but the electrochromic lens module 100A of the present embodiment further includes a color filling layer 160. In the present embodiment, the patterned metal electrode 121 of the opaque touch sensing layer 120 is disposed between the color filling layer 160 and the first transparent substrate 110. For example, the color filling layer 160 of the embodiment is white, and the hollow area C in the patterned metal electrode 121 of the opaque touch sensing layer 120 exposes a portion of the color filling layer 160, so that the driver can see the white color through the gap in the patterned metal electrode 121 on the visible surface 101 of the first transparent substrate 110, so that the driver can further clearly see the shape of the patterned metal electrode 121.
In yet another embodiment of the present invention, the color-filling layer 160 of the electrochromic lens module 100A may further include a light-emitting element. The Light emitting element is, for example, a Light Emitting Diode (LED), but the invention is not limited thereto. The light-emitting element of the color filling layer 160 can also provide a backlight function behind the patterned metal electrode 121, so that the light source can be transmitted to the visible surface 101 through the hollow area C, and the driver can clearly see the shape of the patterned metal electrode 121 in a low-brightness environment. Further, the light emitting elements of the color filling layer 160 can provide different colors of light corresponding to different positions, so that the driver can clearly recognize the pattern of the patterned metal electrode 121.
For example, the material of the patterned metal electrode 121 of the present embodiment may include a conductive material or a plating material. The coating material comprises at least one of silver, copper, titanium, molybdenum, chromium, nickel, aluminum and the like or an alloy material consisting of a plurality of materials.
In another embodiment of the present invention, the electrochromic lens module may have other configurations of the opaque touch sensing layer. Fig. 4 is a schematic plan view of an electrochromic lens module according to yet another embodiment of the invention. Referring to fig. 4, the electrochromic lens module 100B of the present embodiment is substantially similar to the electrochromic lens module 100 described above, and the same elements and connection relationships are not described herein again, but the difference is that the positions of the light-proof touch sensing layer 120 on the back surface of the electrochromic lens module 100B, which correspond to the positions of the visible surface 101, may also be adjacent to the two side edges L3 and L4.
In detail, referring to fig. 4, in the present embodiment, the positions of the opaque touch sensing layer 120 forming the electrode patterns 122-127 corresponding to the visible surface 101 may be adjacent to the side L4 close to the driving, the bottom L2 and the side L3 far from the driving, wherein the corresponding positions of the electrode patterns 123-127 required to facilitate driving operation may be adjacent to the side L4 or the bottom L2, and the corresponding position of the electrode pattern 122 required to avoid driving mistouch may be adjacent to the side L3.
In yet another embodiment of the present invention, the electrochromic lens module may further have other configurations of the opaque touch sensing layer. Fig. 5 is a schematic plan view of an electrochromic lens module according to yet another embodiment of the present invention. Referring to fig. 4, the electrochromic lens module 100C of the present embodiment is substantially similar to the electrochromic lens module 100B described above, and the same elements and connection relationships are not repeated herein, except that the distribution position of the light-proof touch sensing layer 120 on the back surface of the electrochromic lens module 100C corresponding to the position of the visible surface 101 may be also adjacent to the top edge L1.
Fig. 5 is a schematic plan view of an electrochromic lens module according to yet another embodiment of the present invention. In detail, referring to fig. 5, in the present embodiment, the position of the opaque touch sensing layer 120 forming the electrode patterns 122-127 corresponding to the visible surface 101 may be also adjacent to the top edge L1 away from the driver. Thus, it is possible to further avoid operating a part of the functions while driving. For example, the electrode pattern 124 corresponding to the call and the electrode pattern 125 corresponding to the wireless transmission are located near the top edge L1 to remind the driver not to perform these functions while the vehicle is driving, thereby further enhancing safety. In the embodiment, the electrode patterns 122-127 are not equidistantly distributed on the top edge L1, the bottom edge L2, the side edges L3, and the side edges L4 of the visible surface 101, but the invention is not limited thereto, and in other embodiments, the electrode patterns 122-127 may also be equidistantly distributed on the top edge L1, the bottom edge L2, the side edges L3, and the side edges L4 of the visible surface 101.
Fig. 6 is a schematic plan view of an electrochromic lens module according to another embodiment of the invention. Referring to fig. 6, in the present embodiment, the opaque touch sensing layer 120D of the electrochromic lens module 100D includes continuous operation areas. The opaque touch sensing layer 120D further includes a patterned metal electrode 121, and a button pattern is formed by the hollow area D.
