Description

[0001] This case is a divisional application. The parent case application number is 202110427653.8. The parent case application date is April 20, 2021. The parent case name is electronic device. Technical Field

[0002] The present disclosure relates to an electronic device, and more particularly to an electronic device with a solar cell. Background Art

[0003] With the development of technology, solar cells have been widely used in various electronic devices, such as smart glasses. However, since the energy that an electronic device can receive has an upper limit, when the ambient light is too strong (such as outdoors at noon), the energy provided by the solar cell may exceed the upper limit that the electronic device can receive. The excess energy will be converted into heat energy and concentrated at the solar cell, which is easy to cause damage.

[0004] Therefore, an improved electronic device is needed to improve the above problems. Summary of the invention

[0005] The present disclosure provides an electronic device, comprising a solar cell, a first light modulation layer, a transmittance adjustable lens and a control circuit. At least a portion of the first light modulation layer is disposed above the solar cell. The control circuit is electrically connected to the solar cell and the transmittance adjustable lens.

[0069] When read in conjunction with the accompanying drawings, the following embodiments are used to clearly demonstrate the above and other technical contents, features and / or effects of the present disclosure. Through the description of the specific implementation methods, people will further understand the technical means and effects adopted by the present disclosure to achieve the above-mentioned purposes. In addition, since the content disclosed in the present disclosure should be easy to understand and can be implemented by those skilled in the art, all equivalent substitutions or modifications that do not depart from the concepts of the present disclosure should be included in the claims.

[0070] It should be noted that, herein, unless specifically stated otherwise, “a” or “an” element is not limited to a single element but may refer to one or more elements.

[0071] In addition, ordinals such as "first" or "second" in the specification and claims are only used to describe the claimed elements, and do not represent or indicate that the claimed elements have any order, and are not the order between the claimed elements and another claimed element or between the steps of the manufacturing method. The use of these ordinals is only to distinguish one claimed element with a specific name from another claimed element with the same name.

[0072] Furthermore, the term "adjacent" in the specification and claims is used to describe being near each other, but does not necessarily mean being in contact with each other.

[0073] In addition, when an element or a film layer is referred to as being on another element or another film layer, or being referred to as being connected to another element or another film layer, it should be understood that the element or film layer is directly located on another element or another film layer, or is directly connected to another element or film layer, or there may be other elements or film layers between the two (indirectly). But on the contrary, when an element or a film layer is referred to as being "directly on" another element or film layer, or "directly connected to" another element or film layer, it should be understood that there is no intervening element or film layer between the two. When referring to "on" or "above", it includes the situation of direct contact, or there may be one or more other elements between the two, in which case the two may not be in direct contact.

[0074] In the present disclosure, the length and width can be measured by an optical microscope, and the thickness can be measured by a cross-sectional image in an electron microscope, but the method is not limited thereto. In addition, any two values ​​or directions used for comparison may have a certain error. If the first value is equal to the second value, it implies that there may be an error of about 10% between the first value and the second value; if the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0 degrees and 10 degrees.

[0075] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meanings as commonly understood by those skilled in the art to which the present disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined in the embodiments of the present disclosure.

[0076] In addition, the descriptions of "when..." or "when..." in this disclosure indicate situations such as "at the moment, before, or after", and are not limited to situations that occur at the same time, which is explained in advance. The descriptions of "disposed on..." and the like in this disclosure indicate the corresponding positional relationship between two elements, and are not limited to whether the two elements are in contact, unless otherwise specified, which is explained in advance. Furthermore, when the disclosure records multiple effects, if the word "or" is used between the effects, it means that the effects can exist independently, but it does not exclude that multiple effects can exist at the same time.

[0077] In addition, the term "connected" or "coupled" in the specification and claims refers not only to direct connection with another element, but also to indirect connection or electrical connection with another element. In addition, electrical connection includes direct connection, indirect connection or communication between two elements by radio signals.

[0078] In addition, in the specification and claims, the terms "about", "approximately", "substantially", and "roughly" generally mean within 10%, or within 5%, or within 3%, or within 2%, or within 1%, or within 0.5% of a given value or range. The number given here is an approximate number, that is, in the absence of specific instructions for "about", "approximately", "substantially", and "roughly", the meaning of "about", "approximately", "substantially", and "roughly" can still be implied. In addition, the terms "range is from a first value to a second value", "range is between a first value and a second value" mean that the range includes the first value, the second value, and other values ​​therebetween.

[0079] It should be understood that the following embodiments may replace, reorganize, or mix features in several different embodiments to complete other embodiments without departing from the spirit of the present disclosure. Features between embodiments may be mixed and matched as long as they do not violate the spirit of the invention or conflict with each other.

For ease of description, the following description will be based on the case where the electronic device is a smart glasses, but the present disclosure is not limited thereto.

[0081] Figure 1A 1 is a schematic diagram of an electronic device 1 according to some embodiments of the present disclosure, wherein the electronic device 1 is taken as an example of smart glasses, and when a user wears the electronic device 1, the user's line of sight is defined as the Z direction, and the lateral arrangement direction of the lenses is defined as the X direction.

[0082] like Figure 1A As shown, the electronic device 1 includes a solar cell 2, a light modulation module 3, at least one transmittance adjustable lens 4 and a control circuit 5, and the light modulation module 3 includes a first light modulation layer 31. The control circuit 5 can be disposed inside the electronic device 1. Figure 1AThe electronic device 1 only shows that the control circuit 5 is included, but does not mean that the control circuit 5 is placed outside the electronic device 1. When incident light in the environment is incident, the incident light first passes through the first light modulation layer 31 in the light modulation module 3 before reaching the solar cell 2. When the solar cell 2 receives the incident light, it can convert the received light energy into electrical energy and output the energy. The control circuit 5 is electrically connected to the solar cell 2 and can receive the energy provided by the solar cell 2. The control circuit 5 is also electrically connected to the transmittance adjustable lens 4 and can transmit a control signal to the transmittance adjustable lens 4.

[0083] In some embodiments, the solar cell 2 may include a plurality of photodiodes, and the photodiodes may form an array, but the disclosure is not limited thereto.

[0084] In some embodiments, the material of the first light modulation layer 31 may include, for example, a host-guest effect liquid crystal (GHLC), dye liquid crystal, twisted nematic liquid crystal (TN LC), super twisted nematic liquid crystal (STN LC), polymer dispersed liquid crystal (PDLC), cholesterol liquid crystal, polymer stabilized cholesterol liquid crystal structure thin film liquid crystal (PSCT LC), suspended particle material, electrochromic material or polymer network liquid crystal (PNLC), but is not limited thereto.

[0085] Here, the details of the first light modulation layer 31 and the light modulation module 3 are described. Figure 1B is a schematic diagram of the structure of the light modulation module 3 of the electronic device 1 in some embodiments of the present disclosure. Figure 1BAs shown, the first light modulation layer 31 is disposed above the solar cell 2. In addition, the light modulation module 3 includes the first light modulation layer 31, a first substrate 32, a second substrate 33, a first electrode layer 34 and a second electrode layer 35, wherein the first light modulation layer 31 is sandwiched between the first substrate 32 and the second substrate 33. In one embodiment, the second electrode layer 35 may be disposed on the second substrate 33, the first light modulation layer 31 may be disposed between the second electrode layer 35 and the first electrode layer 34, and the first electrode layer 34 may be disposed between the first substrate 32 and the first light modulation layer 31. In addition, the solar cell 2 and the first light modulation layer 31 may be separated by one of the substrates, for example, the solar cell 2 and the first light modulation layer 31 may be separated by the second substrate 33, and the present invention is not limited thereto. In addition, the transmittance of the first light modulation layer 31 can be controlled and adjusted. For example, by applying different voltages to the first electrode layer 34 and the second electrode layer 35, the first light modulation layer 31 can produce different driving states (such as black fog state, white fog state or different transmission states, etc., and not limited to this), and change the transmittance of the first light modulation layer 31. By adjusting the transmittance of the first light modulation layer 31, the energy received by the solar cell 2 (such as the incident amount of light) can be adjusted. In addition, although in the embodiment of Figure 1, the first light modulation layer 31 is disposed in the light modulation module 3, and the first light modulation layer 31 and the solar cell 2 are separated by the lower substrate 33, in other embodiments, the first light modulation layer 31 and the solar cell 2 can also be sandwiched between two substrates (please refer to Figure 8 Embodiment), but not limited thereto.

[0086] Next, the transmittance adjustable lens 4 is described. Please refer to Figure 1A. In some embodiments, each transmittance adjustable lens 4 may also include a light modulating layer, wherein the material of the light modulating layer of the transmittance adjustable lens 4 may be the same as the material of the first light modulating layer 31, so it is not repeated here. The transmittance of the transmittance adjustable lens 4 can be adjusted by the control signal of the control circuit 5. In some embodiments, the control circuit 5 may predetermine the transmittance required by the transmittance adjustable lens 4. For example, the control circuit 5 may have a control logic (for example, but not limited to an algorithm) inside, so the transmittance required by the transmittance adjustable lens 4 can be set according to the ambient light around the electronic device 1, and the transmittance of the transmittance adjustable lens 4 can be changed by adjusting the voltage value or current value of the control signal, or the transmittance required by the transmittance adjustable lens 4 can also be a preset value, but not limited to this. In some embodiments, the electronic device 1 can be designed to allow the user to adjust the transmittance of the transmittance adjustable lens 4 by himself. For example, the control circuit 5 can receive the user's instruction and adjust the voltage value or current value of the control signal, thereby changing the transmittance of the transmittance adjustable lens 4, but not limited to this. In addition, in some embodiments, the transmittance of the adjustable transmittance lens 4 can be set to have an inverse relationship with the size of the control signal, that is, when the control signal is higher, the transmittance of the adjustable transmittance lens 4 will be lower, thereby presenting a lower brightness, but the present disclosure is not limited to this.

[0087] In some embodiments, the control circuit 5 has an energy requirement value (e.g., the energy required for each transmittance adjustable lens 4), so when the solar cell 2 provides energy to the control circuit 5, the control circuit 5 will receive energy of the energy requirement value from the solar cell 2, and the remaining energy will be converted into heat energy or dissipated in other forms. In some embodiments, the transmittance required by the transmittance adjustable lens 4 may change (e.g., through user adjustment or from the intensity of ambient light, but not limited to this), so the energy requirement value of the control circuit 5 may also be adjusted accordingly, so the energy requirement value is a variable value. In some embodiments, the energy requirement value may also be the upper limit of the energy that the control circuit 5 can receive. The present disclosure is not limited to this.

[0088] Incident light with too high energy may exceed the energy requirement value or energy upper limit value of the control circuit 5, thereby causing energy waste or accelerating the speed of damage to electronic components. In this regard, the electronic device 1 of the present disclosure has a light modulation module 3 (including a first light modulation layer 31) disposed on the solar cell 2, which can adjust the amount of incident light received by the solar cell 2 by changing the transmittance of its first light modulation layer 31, so that the energy provided by the solar cell 2 can appropriately meet the energy requirement value or energy upper limit value of the control circuit 5. In some embodiments, when the electronic device 1 is located in a high-brightness environment (such as an outdoor strong light environment), since the electronic device 1 of the present disclosure has a light modulation module 3 (including a first light modulation layer 31) disposed on the solar cell 2, it can adjust the amount of incident light received by the solar cell 2 by changing the transmittance of the first light modulation layer 31, for example, reducing the transmittance of the first light modulation layer 31, so that the amount of incident light received by the solar cell 2 is reduced. In some embodiments, when the electronic device 1 is located in a low-brightness environment, the transmittance of the first light modulation layer 31 can be increased, so that the solar cell 2 can receive enough energy and provide it to the control circuit 5, so that the control circuit 5 can control the transmittance adjustable lens 4 (for example, provide a control signal). In some embodiments, since the solar cell 2 can control the transmittance adjustable lens 4 in a low-brightness environment, the transmittance adjustable lens 4 can still achieve the required transmittance in a low-brightness environment. For example, when indoors, the transmittance adjustable lens 4 can be in a state of not being completely transparent (non-transmittance is 100%), so even indoors, the transmittance adjustable lens 4 has at least some effect of shielding the eyes, which is beneficial for shielding eye diseases or maintaining privacy.

[0089] In order to achieve the above functions, the electronic device 1 of the present disclosure may have a special architecture. Figure 2A is a schematic diagram of the architecture of the electronic device 1 of some embodiments of the present disclosure, and please also refer to Figure 1A and Figure 1B .in Figure 2A All the components with reference numbers are included in the electronic device 1. Figure 2A It is only for illustration, and not all the numbered components are located outside the electronic device 1 .

[0090] like Figure 2A As shown, in addition to the aforementioned solar cell 2 , light modulation module 3 (including the first light modulation layer 31 ), transmittance adjustable lens 4 and control circuit 5 , the electronic device 1 may further include a light modulation layer control circuit 6 .

[0091] The light modulation layer control circuit 6 is electrically connected to the solar cell 2 and the light modulation module 3. The light modulation layer control circuit 6 can also receive energy provided by the solar cell 2, and can transmit a light modulation layer control signal to the light modulation module 3 according to the received energy to adjust the transmittance of the first light modulation layer 31 of the light modulation module 3 so that the energy incident to the solar cell 2 is adjusted.

[0092] In some embodiments, the light modulation layer control circuit 6 may pre-set an energy threshold value, and compare the energy provided by the solar cell 2 (e.g., the energy provided to the control circuit 5) with the energy threshold value, thereby determining the adjustment method of the transmittance of the first light modulation layer 31. In some embodiments, the energy threshold value may be the energy requirement value or the energy upper limit value of the control circuit 5.

[0093] In some embodiments, the incident light may be indoor incident light or outdoor incident light. For example, the energy of outdoor incident light is 10 to 30 times that of indoor incident light. Therefore, in an outdoor environment, the energy incident to the solar cell 2 may be much higher than the energy threshold value. At this time, the light modulation layer control circuit 6 may reduce the transmittance of the first light modulation layer 31 through the light modulation layer control signal, so that the intensity of the incident light incident to the solar cell 2 is reduced, and the energy provided by the solar cell 2 to the control circuit 5 is reduced; while indoors, the intensity of the incident light incident to the solar cell 2 may be less than the energy threshold value. At this time, the light modulation layer control circuit 6 may increase the transmittance of the first light modulation layer 31 through the light modulation layer control signal, so that the intensity of the incident light incident to the solar cell 2 is increased, and the energy provided by the solar cell 2 is increased. The present disclosure is not limited to this.

[0094] In some embodiments, since the energy requirement of the control circuit 5 may change, the control circuit 5 may transmit the energy requirement to the light modulation layer control circuit 6 so that the light modulation layer control circuit 6 may adjust the energy threshold according to the energy requirement. The present disclosure is not limited thereto.

[0095] Figure 2B 1 is a schematic diagram of the structure of the electronic device 1 of some embodiments of the present disclosure, and please refer to FIG. Figure 2A .in Figure 2B All the components with reference numbers are included in the electronic device 1. Figure 2B This is only for illustration and does not mean that all the numbered components are located outside the electronic device 1 .

[0096] Figure 2BThe control circuit 5 of the embodiment may include a maximum power point tracking (MPPT) circuit 6a, and the maximum power point tracking circuit 6a may be electrically connected to the light modulation module 3. The maximum power point tracking circuit 6a has a maximum power point tracking (MPPT) function, so it can automatically adjust the transmittance of the first light modulation layer 31 of the light modulation module 3 according to the ambient light. Since the control circuit 5 of this embodiment includes the maximum power point tracking circuit 6a, the electronic device 1 may not have Figure 2A The light modulation layer control circuit 6 in the embodiment. In addition, in some embodiments, the maximum power point tracking circuit 6a may be disposed above the solar cell 2. The present disclosure is not limited thereto.

[0097] Based on the above description, the basic structure of the electronic device 1 can be understood.

[0098] Next, more details of the light modulation module 3 and the transmittance adjustable lens 4 will be described. Figure 3A is a schematic diagram of the light modulation module 3 and the transmittance adjustable lens 4 of some embodiments of the present disclosure, and please also refer to Figure 1A to Figure 2B .

[0099] like Figure 3A As shown, the electronic device 1 may include two lenses (a transmittance adjustable lens 4R and a transmittance adjustable lens 4L) on the left and right. Each transmittance adjustable lens 4R or 4L may include a first lens area 41 and a second lens area 42. The first lens area 41 may be located at the side of the transmittance adjustable lens 4, for example, adjacent to the eyeglass tripod 8 or farther away from the solar cell 2, for blocking incident light from the side. The second lens area 42 may be located in an area closer to the solar cell 2.

[0100] In some embodiments, according to the functions of the first lens area 41 and the second lens area 42, the first lens area 41 may have a lower transmittance, such as being similar to a black fog state, to reduce light penetration, while the second lens area 42 may have a higher transmittance to allow the user to see normally, but the present invention is not limited thereto. In some embodiments, the transmittances of the first lens area 41 and the second lens area 42 may also be the same, but the present invention is not limited thereto.

[0101] Since the first lens area 41 and the second lens area 42 may have different transmittances, the control circuit 5 may transmit different control signals to the first lens area 41 and the second lens area 42 to respectively control the transmittances of the first lens area 41 and the second lens area 42. For example, the control signal may include a first control signal and a second control signal, the first control signal is used to control the first lens area 41, and the second control signal is used to control the second lens area 42. The present disclosure is not limited thereto.

[0102] In some embodiments, the transmittance of the first lens area 41 may be between 0.01% and 99.99%, but not limited thereto. In some embodiments, the transmittance of the second lens area 42 may be between 0.01% and 99.99%, but not limited thereto. In some embodiments, the transmittance of the first lens area 41 may be substantially the same as the transmittance of the second lens area 42, but not limited thereto. In some embodiments, the transmittance of the first lens area 41 may be different from the transmittance of the second lens area 42, for example, the transmittance of the first lens area 41 is less than the transmittance of the second lens area 42, but not limited thereto.

[0103] In some embodiments, the light modulation layer of the first lens area 41 and the second lens area 42 of the transmittance adjustable lens 4R or 4L may be made of the same material, but not limited thereto. In some embodiments, the light modulation layer of the first lens area 41 and the second lens area 42 may also be made of different materials. For example, the material of the light modulation layer of the first lens area 41 may include cholesterol liquid crystal, such as polymer stabilized cholesterol liquid crystal structure thin film liquid crystal (PSCT LC), to achieve the effect of color change at different temperatures, but not limited thereto. The material of the light modulation layer of the second lens area 42 may include host-guest effect liquid crystal (GHLC), but not limited thereto. In some embodiments, the first lens area 41, the second lens area 42 of the transmittance adjustable lens 4R or 4L and the first light modulation layer 31 of the light modulation module 3 may be made of the same material, but not limited thereto. In some embodiments, the first lens area 41, the second lens area 42 of the transmittance adjustable lens 4R or 4L and the first light modulation layer 31 of the light modulation box 3 may be made of different materials, but not limited thereto. In one embodiment, the first lens region 41 and the second lens region 42 may share the same light modulation layer, but this is not limited.

[0104] In some embodiments, cholesterol liquid crystal may be disposed on a portion of the eyeglass stand 8 so that the portion of the eyeglass stand 8 may also achieve a color-changing effect at different temperatures, but the invention is not limited thereto.

[0105] Next, the internal structure of the transmittance adjustable lens 4R or 4L is described. Figure 3B is a cross-sectional schematic diagram of the light modulation module 3 and the transmittance adjustable lens 4 along the user's line of sight (Z direction) of some embodiments of the present disclosure, and please also refer to Figures 1A to 3A .in, Figure 3B It can be three independent areas, such as the transmittance adjustable lens 4R, the light modulation module 3 and the transmittance adjustable lens 4L. For the convenience of description, the transmittance adjustable lens 4R is used for description below.

[0106] like Figure 3BAs shown, the first lens region 41 of the transmittance adjustable lens 4R may include a second light modulation layer 411, a third substrate 412, a fourth substrate 413, a third electrode layer 414 and a fourth electrode layer 415, wherein the fourth electrode layer 415 is disposed on the fourth substrate 413, the second light modulation layer 411 is disposed on the fourth electrode layer 415, the third electrode layer 414 is disposed on the second light modulation layer 411, and the third substrate 412 is disposed on the third electrode layer 414.

[0115] like Figure 4A As shown, along the user's line of sight (Z direction), the second light modulation layer 411 of the first lens area 41 has a first thickness d1, wherein the first thickness d1 can be the average thickness of the second light modulation layer 411 in the user's line of sight (Z direction), wherein the average thickness can be obtained by taking the average value of three points in a cross section.

In some embodiments, the first thickness d1 is different from the second thickness d2, for example, the first thickness d1 is less than the second thickness d2. In some embodiments, the first thickness d1 can be between 3 and 500 micrometers (μm) (3μm≦d1≦500μm), and the first thickness d1 is less than the second thickness d2, but the present disclosure is not limited thereto.

In addition, in this embodiment, the third light modulation layer 421 and the fifth electrode layer 424 have an arc-shaped raised area 426 raised along the user's line of sight (Z direction). By combining the arc-shaped raised area 426 with the transmittance of the second lens area 42, the incident focal length of the light in the second lens area 42 can be adjusted, which can be like the effect of a myopia lens or a hyperopia lens. Figure 4B is a cross-sectional schematic diagram of the first lens area 41 and the second lens area 42 of some embodiments of the present disclosure, and please also refer to Figures 1A to 4A For the sake of convenience, the following uses the transmittance adjustable lens 4R as an example.

In some embodiments, the sixth electrode layer 425 includes annular electrodes 425a of different sizes, and the annular electrodes 425a are arranged in order according to size and surround each other, so that the second lens area 42 can form an effect like a Fresnel lens, so when different voltages (such as electrical control) or light energies (such as light control) are applied to the sixth electrode layer 425, the second lens area 42 can produce an effect like a convex lens or a concave lens, which can be like the effect of a myopia lens or a hyperopia lens.

[0119] In some embodiments, there is a gap r1 between every two adjacent annular electrodes 425a, wherein the gap r1 may be between 1.5 and 4.5 micrometers (μm) (i.e., 1.5 μm≦r1≦4.5 μm), but is not limited thereto.
