[0085] Before introducing the embodiments of the present application, some terms that may be used in the following content are first explained and illustrated.

[0086] Light intensity, the luminous flux of light received per unit area.

[0087] Analog-to-digital converter (ADC or A / D), is a kind of device used to convert continuous signals in analog form into discrete signals in digital form. An analog-to-digital converter can provide signals for measurement. The working principle of an analog-to-digital converter can include three basic steps of sampling, quantization and coding.

[0088] Operational amplifier (op amp), simply called op amp, is a kind of high gain voltage amplifier with direct coupling, differential mode input and usually single-ended output. Operational amplifier can produce an output potential that is tens of thousands times larger than the input potential difference.

[0089] Direct current to direct current converter, also known as DC / DC converter, DC transformer or DC converter, is a kind of circuit or electromechanical device for converting electric energy, which can convert DC power into DC power with different voltage.

[0090] Polarizing optical filter (POL), also known as polarizer or polaroid, refers to an optical element that can convert natural light into polarized light.

[0091] Active area (AA), refers to the part of the display screen of an electronic device that users can actually see image content and interact with through touch. In simple terms, the active area does not include the screen frame, black border and any part without display or touch function.

[0092] Anti-reflective coating (AR), a kind of surface optical coating, which increases the transmittance by reducing the reflection of light. In complex optical systems, it can improve the contrast by reducing scattered light in the system.

[0093] Ultraviolet (UV), refers to electromagnetic radiation with a wavelength range of 10 nanometers to 400 nanometers. Ultraviolet is part of sunlight, but can also be emitted by other light sources such as electric arc, mercury lamp and black light, etc.

[0094] Optical clear adhesive (OCA), also known as optical clear adhesive, is an adhesive used for bonding transparent optical components. It is characterized by colorless transparency, high light transmittance and good bonding strength. Optical clear adhesive can be widely used in the manufacture of electronic devices such as mobile phones, tablets, laptops, bracelets and watches.

[0095] The film is formed by high transparency and low viscosity materials such as silicone.

[0096] In order to make the watch, bracelet, mobile phone and other electronic devices can more accurately test the intensity of light in the environment, the application embodiment provides a light intensity detection assembly, the solar conversion device in the light intensity detection assembly can generate an electrical signal while converting light energy into electrical energy, the detection device in the light intensity detection assembly can detect the intensity of the electrical signal, and the intensity of the electrical signal can be used to determine the intensity of the light in the environment.

[0097] Fig. 1 shows a schematic diagram of a light intensity detection assembly 10 provided by an embodiment of the application. The light intensity detection assembly 10 can include a light energy conversion device 11 and a detection device 12. The light energy conversion device 11 is connected in parallel with the detection device 12, or in other words, the two ends of the detection device 12 are respectively connected to the two ends of the light energy conversion device 11.

[0098] In some examples, the light energy conversion device 11 can be used to convert part or all of the light energy of the incident light (e.g. sunlight, light) into electrical energy. In some scenarios, the light energy conversion device can also be referred to as a solar conversion device, and the following examples are collectively referred to as a light energy conversion device.

[0099] Fig. 2 shows a schematic diagram of a structure of a light energy conversion device 11. The light energy conversion device 11 can be a layered structure. For example, the light energy conversion device 11 can include a functional layer 11A and a functional layer 11B. The functional layer 11A can be plate-shaped or film-shaped, and can be used to convert the light energy of the incident light into electrical energy. The functional layer 11B can be film-shaped, and can be used to increase the proportion of light energy absorption of the light energy conversion device 11.

[0100] In some examples, the functional layer 11A can be composed of a material capable of converting light energy into electrical energy. For example, the functional layer 11A can be composed of one or more of the following materials: single crystal silicon, polycrystalline silicon, amorphous silicon, gallium arsenide (GaAs), gallium aluminum arsenide (GaAlAs), indium phosphide (InP) or cadmium sulfide (CdS) and the like.

[0101] In some examples, the functional layer 11B, which can also be referred to as an anti-reflection layer 11B, can increase the proportion of light energy absorbed by the light energy conversion device 11 by reducing the reflectivity of the incident light rays incident on the light energy conversion device 11. By way of example, the functional layer 11B can be composed of one or more of the following materials: silicon dioxide, titanium dioxide, zirconium dioxide, or magnesium fluoride, etc. By way of example, the functional layer 11B can be composed of two layers of silicon dioxide and magnesium fluoride arranged in a stack.

[0102] When the light rays are incident on the light energy conversion device 11, the incident light rays can first pass through the functional layer 11B and then be incident on the functional layer 11A. With the anti-reflection effect of the functional layer 11B on the incident light rays, fewer light rays are reflected back into the environment when the light rays are incident on the functional layer 11B, and more light rays pass through the functional layer 11B and are incident on the functional layer 11A, thereby converting the light energy in the light rays into electrical energy via the functional layer 11A.

[0103] Referring to FIG. 1, in the case where a loop is formed at both ends of the light energy conversion device 11, the electrical energy formed by the light energy conversion device 11 by converting light energy can be output in the form of an electric current. The aforementioned detection device connected in parallel at both ends of the light energy conversion device 11 can detect the intensity of the electrical signal generated by the light energy conversion device 11.

[0104] In some examples, the detection device 12 can include an analog-to-digital converter 12A, which can be used to detect the intensity of the electrical signal in the loop formed by the aforementioned light energy conversion device 11. By way of example, the analog-to-digital converter 12A connected in parallel at both ends of the light energy conversion device 11 can convert the direct current signal generated by the light energy conversion device 11 into a voltage signal, which can be used to determine the intensity of the light rays incident on the light energy conversion device 11.

[0105] Here, the direct current signal generated by the light energy conversion device 11 can be an analog signal, and the voltage signal obtained after processing by the analog-to-digital converter 12A can be a digital signal. After subsequent processing, the digital signal can obtain information about the intensity of the aforementioned light rays incident on the light energy conversion device 11.

[0106] One possible scenario is that the intensity of the direct current signal generated by the light energy conversion device 11 is small, and the signal is relatively weak. After analog-to-digital conversion, the voltage signal formed by the signal is also relatively weak. The deviation between the light intensity determined using such a voltage signal and the actual light intensity can be large, or in other words, the accuracy of the light intensity detected by the component 10 for detecting the intensity of the light rays shown in FIG. 1 can be further improved.

[0107] In order to improve the accuracy and reliability of the light intensity detection result, as shown in FIG. 3, the application provides another light intensity detection assembly 20. Similar to the light intensity detection assembly 10, the light intensity detection assembly 20 also includes a light energy conversion device 21 and a detection device 22. Different from the light intensity detection assembly 10, the detection device 22 of the light intensity detection assembly 20 can be provided with an operational amplifier 22B and an analog-to-digital converter 22A.

[0108] In the light intensity detection assembly 20, the light energy conversion device 21 can be used to convert the light energy of the incident light into electrical energy. The light energy conversion device 21 can have a layered structure. For example, the light energy conversion device 21 can include a functional layer 21A and a functional layer 21B. The functional layer 21A can be used to convert the light energy in the light into electrical energy. The functional layer 21B can be used to improve the proportion of the absorption of the light energy by the light energy conversion device 21.

[0109] In some examples, the functional layer 21A can be composed of a material capable of converting light energy into electrical energy, such as gallium arsenide, etc.

[0110] In some examples, the functional layer 21B can be used to reduce the reflectivity of the incident light incident on the light energy conversion device 21. For example, the functional layer 21B can be composed of a material such as magnesium fluoride.

[0111] The description of the light energy conversion device 21 can refer to the related content of the light energy conversion device 11 described above, which will not be repeated here.

[0112] The detection device 22 can be connected in parallel with the light energy conversion device 21. The detection device 22 can be used to detect the intensity of the electrical signal generated when the light energy conversion device 21 converts the light energy into electrical energy.

[0114] In other words, the electrical signal generated by the light energy conversion device 21 is input to the operational amplifier 22B, and the operational amplifier 22B outputs the amplified electrical signal to the analog-to-digital converter 22A.

[0115] In some examples, in the case that a loop is formed at both ends of the light energy conversion device 21, the electrical energy converted by the light energy conversion device 21 can be output in the form of a current, which can be captured by the operational amplifier 22B connected in parallel at both ends of the light energy conversion device 21. The operational amplifier 22B can amplify the aforementioned current signal input from the input end and output the amplified electrical signal (analog signal) to the analog-to-digital converter 22A. The analog-to-digital converter 22A can convert the input amplified electrical signal (analog signal) into a digital signal, which can be used to determine the intensity of the incident light.

[0116] In the foregoing examples, the detection device is connected in parallel at both ends of the light energy conversion device. In one possible case, the electrical properties (e.g., resistance value) of the light energy conversion device itself can change over time as the device is used. In this case, the intensity of the electrical signal detected by the detection device can change over time as the light energy conversion device is used, which can in turn cause the error in the detection result of the light intensity to increase. In addition, the light energy conversion device can be used as a packaged device.

The analog-to-digital converter 42A can convert the input amplified electrical signal (analog signal) into a digital signal, which can be used to determine the intensity of the incident light.

[0130] In some examples, in order to reduce the interference of other electronic components in the circuit on the electrical signal generated by the light energy conversion device 41, or in other words, in order to make the intensity of the electrical signal measured by the detection device 42 connected in parallel to the resistance 43 consistent with the intensity of the electrical signal generated by the light energy conversion device 41, the resistance 43 and the light energy conversion device 41 can be directly connected, or in other words, no other electronic components are connected between the resistance 43 and the light energy conversion device 41.

[0160] The light intensity detection assemblies provided in the foregoing examples can be used to detect the intensity of incident light or the intensity of part of the incident light (e.g., the target light or the light other than the target light). The light intensity detection assemblies provided in the following examples can be used to simultaneously detect the intensity of two or more types of light.

[0161] FIG. 10 shows another light intensity detection assembly 70 provided by the embodiments of the present application. The light intensity detection assembly 70 includes a light energy conversion device 71, a light energy conversion device 72, a detection device 73, and a single-pole double-throw switch 74.

[0162] The light energy conversion device 71 and the light energy conversion device 72 are connected in parallel. One end of the light energy conversion device 71 is connected to one end of the light energy conversion device 72. The other end of the light energy conversion device 71 is connected to a first contact of the single-pole double-throw switch 74. The other end of the light energy conversion device 72 is connected to a second contact of the single-pole double-throw switch 74. The common end of the single-pole double-throw switch 74 is connected to the end where the light energy conversion device 71 and the light energy conversion device 72 are connected to each other.

[0163] When the common end of the single-pole double-throw switch 74 is connected to the first contact, the light energy conversion device 71 can form a first loop. When the common end of the single-pole double-throw switch 74 is connected to the second contact, the light energy conversion device 72 can form a second loop.

[0164] One end of the detection device 73 is connected to the common end of the single-pole double-throw switch 74. The other end of the detection device 73 can be connected to the end of the light energy conversion device 71 away from the single-pole double-throw switch 74 and the end of the light energy conversion device 72 away from the single-pole double-throw switch 74, respectively.

[0165] In this example, when the common terminal of the single-pole double-throw switch 74 is connected with the first contact, or in other words, when the first loop is closed, the detection device 73 is connected in parallel across the light energy conversion device 71, in which case the detection device 73 can be used to detect the electrical signal generated by the light energy conversion device 71; when the common terminal of the single-pole double-throw switch 74 is connected with the second contact, or in other words, when the second loop is closed, the detection device 73 is connected in parallel across the light energy conversion device 72, in which case the detection device 73 can be used to detect the electrical signal generated by the light energy conversion device 72.

Details about the structure of the light energy conversion device 71 and the structure of the light energy conversion device 72 can be referred to the foregoing description, and will not be described here in detail.

[0167] The detection device 73 can include an analog-to-digital converter, which can be used to convert the electrical signal generated by the light energy conversion device 71 into a digital signal, thereby determining the intensity of the incident light rays, or which can be used to convert the electrical signal generated by the light energy conversion device 72 into a digital signal, thereby determining the intensity of the light rays other than the target light rays in the incident light rays.

[0168] In some examples, the detection device 73 can further include an operational amplifier, which can be used to amplify the electrical signal generated by the light energy conversion device 71 or the electrical signal generated by the light energy conversion device 72, and then input into the analog-to-digital converter of the detection device 73. After the electrical signal amplified by the operational amplifier, the subsequent analog-to-digital conversion process has less signal loss, and the signal detected by the detection device 73 is more authentic.

[0169] Since the intensity of the incident light rays or the intensity of the light rays in the incident light rays can be different at different times, in order to enable the detection device 73 to more authentically detect the intensity of the electrical signal generated by the incident light rays at the same time or close to the same time and the intensity of the electrical signal generated by the light rays other than the target light rays in the incident light rays, the common terminal of the foregoing single-pole double-throw switch 74 can be quickly switched to be connected with the first contact or the second contact.

[0170] For example, the common terminal of the single-pole double-throw switch 74 can be connected to the second contact at p1+△p, or the second loop is connected at p1+△p, where △p is less than or equal to the preset time length.

[0171] The light intensity detection assembly 70 can determine the intensity of the incident light and the intensity of the light other than the target light in the incident light, and then the intensity of the target light can be calculated. The specific calculation method of the intensity of the target light will be described in detail below, and will not be expanded here.

In the case of the first loop connection, the detection device 83 can detect the intensity of the electrical signal passing through the resistor 84, or in other words, in this case, the detection device 83 can detect the intensity of the electrical signal corresponding to the electrical energy generated by the light energy conversion device 81 (i.e. the electrical signal corresponding to the incident light). In the case of the second loop connection, the detection device 83 can detect the intensity of the electrical signal passing through the resistor 84, or in other words, in this case, the detection device 83 can detect the intensity of the electrical signal corresponding to the electrical energy generated by the light energy conversion device 82 (i.e. the electrical signal corresponding to the light other than the target light in the incident light).

[0178] The detection device 83 can include an analog-to-digital converter 83A, which can be used to convert the electrical signal generated by the light energy conversion device 81 into a digital signal, thereby determining the intensity of the incident light, or which can be used to convert the electrical signal generated by the light energy conversion device 82 into a digital signal, thereby determining the intensity of the light other than the target light in the incident light.

[0179] In some examples, the detection device 83 can further include an operational amplifier 83B, which can be used to amplify the electrical signal generated by the light energy conversion device 81 or the electrical signal generated by the light energy conversion device 82 before inputting into the analog-to-digital converter 83A of the detection device 83. After the electrical signal amplified by the operational amplifier 83B, the subsequent analog-to-digital conversion process has less signal loss, and the authenticity of the signal detected by the detection device 83 is better.

[0180] In some examples, the resistor 84 can be directly connected to the light energy conversion device 81 or the light energy conversion device 82, or in other words, no other electronic components are connected between the resistor 84 and the light energy conversion device 81 or the light energy conversion device 82.

[0181] Similar to the single-pole double-throw switch 74 in FIG. 10, the common terminal of the single-pole double-throw switch 85 in the light intensity detection assembly 80 can be quickly switched to be connected to the first contact or the second contact, thereby obtaining the intensity of the incident light and the intensity of the light other than the target light in the incident light at the same time as much as possible, and improving the accuracy of light intensity detection.

[0194] Fig. 14 shows a structure of a light intensity detection assembly 200 according to an embodiment of the present application. Similar to the light intensity detection assembly 100 in Fig. 13, the light intensity detection assembly 200 includes a light energy conversion device 210A, a light energy conversion device 210B, a detection device 220A, a detection device 220B, a resistor 230A and a resistor 230B.

[0198] The light ray intensity detection assembly 200 in FIG. 14 can be used to detect the intensity of the incident light rays and the intensity of the target light rays, or can be used to detect the intensity of the target light rays and the intensity of the light rays other than the target light rays in the incident light rays. The intensity of the light rays other than the target light rays in the incident light rays can be calculated from the intensity of the incident light rays and the intensity of the target light rays, and the intensity of the incident light rays can also be calculated from the intensity of the target light rays and the intensity of the light rays other than the target light rays in the incident light rays.

[0199] The intensity of the electrical signal generated by the light energy conversion device is related to the intensity of the light rays incident on the light energy conversion device on the one hand, and is also related to the performance of the light energy conversion device on the other hand. A larger area of the light energy conversion device can capture more energy of the light rays in a unit of time, and thus the intensity of the electrical signal generated is stronger. Generally, the size of a single light energy conversion device is limited. In order to obtain a stronger electrical signal and improve the accuracy and reliability of the light ray intensity detection assembly in detecting the intensity of the light rays, a plurality of one kind of light energy conversion devices can be connected in parallel in the light ray intensity detection assembly. Based on this, FIG. 15 exemplarily provides a light ray intensity detection assembly 300.

[0200] As shown in FIG. 15, the light ray intensity detection assembly 300 can include a plurality of first light energy conversion devices (G1, G2…G n ) and a plurality of second light energy conversion devices (V1, V2…V m), m, n are positive integers. The plurality of first light energy conversion devices are connected in parallel to form a first light energy conversion device group, and the first light energy conversion device group is connected in series with the resistor R1 to form a first loop. The plurality of second light energy conversion devices are connected in parallel to form a second light energy conversion device group, and the second light energy conversion device group is connected in series with the resistor R2 to form a second loop.

[0201] The first light energy conversion device and the second light energy conversion device can be any two of the light energy conversion device 11, the light energy conversion device 51, and the light energy conversion device 61.

[0202] Exemplarily, the structure of the first light energy conversion device can be similar to that of the light energy conversion device 11 in the foregoing examples, and is used to convert the light energy of the incident light into electrical energy. The structure of the second light energy conversion device can be similar to that of the light energy conversion device 61 in the foregoing examples, and can be used to convert the light energy of the light other than the target light in the incident light into electrical energy.

[0203] Exemplarily, the structure of the first light energy conversion device can be similar to that of the light energy conversion device 11, and is used to convert the light energy of the incident light into electrical energy; the structure of the second light energy conversion device can be similar to that of the light energy conversion device 51, and can be used to convert the light energy of the target light in the incident light into electrical energy.

[0204] Exemplarily, the structure of the first light energy conversion device can be similar to that of the light energy conversion device 61 in the foregoing examples, and can be used to convert the light energy of the light other than the target light in the incident light into electrical energy. The structure of the second light energy conversion device can be similar to that of the light energy conversion device 51 in the foregoing examples, and can be used to convert the light energy of the target light in the incident light into electrical energy.

[0205] The physical structure and circuit implementation of the light intensity detection assembly provided by the embodiments of the present application are described above, and the method for detecting the light intensity by using the light intensity detection assembly is described below. It should be noted that the following method is only exemplary, and based on the electrical signal generated by the light energy conversion device, those skilled in the art can also use other more methods to determine the light intensity, which is not limited in the present application.

[0206] For example, in the case where the light intensity detection assembly only contains one light energy conversion device, the intensity of the electrical signal detected by the detection device in the light intensity detection assembly is denoted as x, the area of the light energy conversion device in the light intensity detection assembly is denoted as s, the intensity of the light absorbed by the light energy conversion device can be denoted as y, and the test result of the light intensity determined by using the standard light intensity test method at the same time is denoted as z.

[0207] By measuring the intensity of the electric signal and the test result of the intensity of the standard light corresponding to the electric signal for multiple times, a conversion relationship between the two physical quantities can be established, for example, On this basis, in the case that the intensity of the detected electric signal is x0, the light intensity y0 output by the light intensity detection assembly can be calculated by using the aforementioned calculation formula, i.e.

[0208] For example, assuming that the incident light in FIG. 1 incident on the light energy conversion device 11 is sunlight, the area of the light energy conversion device 11 for receiving the sunlight is A1, the intensity of the electric signal detected by the detection device 12 at time t1 is x1, and the intensity y1 of the sunlight detected by the light intensity detection assembly 10 at time t1 can be approximately wherein f1 can be used to indicate the conversion relationship between the intensity x of the electric signal determined by the above method and the intensity z of the sunlight determined by the standard method.

[0209] For example, assuming that the light intensity detection assembly 50 in FIG. 7 is used to detect the intensity of ultraviolet light, i.e., the target light in FIG. 7 is ultraviolet light. The light energy conversion device 51 can be used to convert the light energy of the ultraviolet light in the sunlight into electric energy, the area of the light energy conversion device 51 is A2, the intensity of the electric signal detected by the detection device 52 at time t2 is x2, and the intensity y2 of the ultraviolet light detected by the light intensity detection assembly 50 at time t2 can be approximately wherein f2 can be used to indicate the conversion relationship between the intensity x of the electric signal determined by the above method and the intensity z of the ultraviolet light determined by the standard method.

[0210] For example, in the case that two light energy conversion devices are included in the light intensity detection assembly, the area of one light energy conversion device in the light intensity detection assembly is denoted as s1, the area of the other light energy conversion device is denoted as s2, the intensity of the electric signal corresponding to the light energy conversion device with the area s1 in the electric signal detected by the detection device is denoted as x1, and the intensity of the electric signal corresponding to the light energy conversion device with the area s2 is denoted as x2. The intensity of the incident light absorbed by the light energy conversion device, the intensity of the target light, and the intensity of the other light in the incident light other than the target light can be denoted as y1, y2, y3, respectively, and the test results of the intensity of the incident light, the intensity of the target light, and the intensity of the other light in the incident light other than the target light determined by the standard light intensity test method at the same time are denoted as z1, z2, z3, respectively.

[0211] In the case where the light energy conversion device with an area of s1 is used to convert the light energy of the incident light into electric energy and the light energy conversion device with an area of s2 is used to convert the light energy of the light other than the target light into electric energy, the conversion relationship between (z1, z2, z3) and (x1, x2, x3, s1, s2, s3) can be established by measuring the intensity of the electric signal and the intensity of the standard light multiple times.

[0212] Exemplarily,

[0213] On this basis, in the case where the intensity of the detected electric signal is a and b respectively, the light intensity y output by the light intensity detection component can include the intensity y1 of the incident light, the intensity y2 of the target light and the intensity y3 of the light other than the target light in the incident light, respectively:

[0214] In the case where the light energy conversion device with an area of s1 is used to convert the light energy of the incident light into electric energy and the light energy conversion device with an area of s2 is used to convert the light energy of the target light, the conversion relationship between (z1, z2, z3) and (x1, x2, x3, s1, s2, s3) can be established by measuring the intensity of the electric signal and the intensity of the standard light multiple times.

[0215] Exemplarily,

[0216] On this basis, in the case where the intensity of the detected electric signal is a and b respectively, the light intensity y output by the light intensity detection component can include the intensity y1 of the incident light, the intensity y2 of the target light and the intensity y3 of the light other than the target light in the incident light, respectively:

[0217] In the case where the light energy conversion device with an area of s1 is used to convert the light energy of the target light into electric energy and the light energy conversion device with an area of s2 is used to convert the light energy of the light other than the target light into electric energy, the conversion relationship between (z1, z2, z3) and (x1, x2, x3, s1, s2, s3) can be established by measuring the intensity of the electric signal and the intensity of the standard light multiple times.

[0218] Exemplarily,

[0219] On this basis, in the case where the intensity of the detected electric signal is a and b respectively, the light intensity y output by the light intensity detection component can include the intensity y1 of the incident light, the intensity y2 of the target light and the intensity y3 of the light other than the target light in the incident light, respectively:

[0220] For example, assume that the light intensity detection component 100 in FIG13 can be used to detect the intensity of sunlight and ultraviolet light. That is, the incident light in FIG13 is sunlight and the target light is ultraviolet light. The light energy conversion device 110A is used to convert the light energy of sunlight into electrical energy, and the light energy conversion device 110B is used to convert the light energy of sunlight other than ultraviolet light into electrical energy.

[0221] The area of ​​the light energy conversion device 110A is A3, the area of ​​the light energy conversion device 110B is A4, the intensity of the electrical signal detected by the detection device 120A at time t3 is x3, and the intensity of the electrical signal detected by the detection device 120B at time t3 is x4. The intensity y1 of the sunlight detected by the light intensity detection component 100 at time t3 can be The intensity of ultraviolet light y2 can be

[0222] Among them, g1 can be used to indicate the relationship between the intensity of the electrical signal of the photoelectric conversion device 110A determined by the above method and the intensity of sunlight determined by the standard method, and g2 can be used to indicate the relationship between the intensity of the electrical signal of the photoelectric conversion device 110A determined by the above method, the intensity of the electrical signal of the photoelectric conversion device 110B and the intensity of ultraviolet light determined by the standard method.

[0223] For example, in the light intensity detection component 300 shown in FIG15 , there are multiple photosynthetic energy conversion devices of the same type connected in parallel. The ratio of the total intensity of the electrical signal generated by the photosynthetic energy conversion device detected by the detection device to the total area of ​​the photosynthetic energy conversion device can be used to determine the intensity of the electrical signal generated by the photosynthetic energy conversion device per unit area, and then perform corresponding calculations.

[0224] For example, assuming that in FIG15 , the specifications of the same type of light energy conversion devices are the same, that is, the area of ​​each light energy conversion device in the same type of light energy conversion device is the same. n ) is A0, the total number of the first light energy conversion devices is n, and the total intensity of the electrical signal generated by the light energy conversion of the first light energy conversion device is x g The second light energy conversion device (V1, V2...V m ) is B0, the total number of the second light energy conversion devices is m, and the total intensity of the electrical signal generated by the light energy conversion of the second light energy conversion devices is x v , m and n are positive integers. Here, the first light energy conversion device is used to convert sunlight energy into electrical energy, and the second light energy conversion device is used to convert sunlight energy other than ultraviolet rays into electrical energy.

[0225] In this case, the intensity of the sunlight detected by the light intensity detection assembly 300 can be denoted as The intensity of the ultraviolet light detected can be denoted as

[0226] Wherein, g1 can be used to indicate the relationship between the intensity of the electrical signal generated by the first light energy conversion device determined by the above method and the intensity of the sunlight determined by the standard method, and g2 can be used to indicate the relationship between the intensity of the electrical signal generated by the second light energy conversion device determined by the above method and the intensity of the ultraviolet light determined by the standard method.

[0227] As shown in FIG. 16, another light intensity detection assembly 400 provided by the embodiments of the present application can include a test module 410 and a battery 430.

[0228] Wherein, the test module 410 can be used to test the intensity of the light. For example, the test module 410 can be any one of the light intensity detection assemblies in FIGS. 1, 5, 11, 13 or 15. The battery 430 can be used to store the electrical energy converted by the light energy conversion device in the test module 410.

[0229] In some examples, the light intensity detection assembly 400 can further include a DC / DC converter 420, which can adjust the electrical energy generated by the light energy conversion device in the test module 410 and input it to the battery 430 for storage.

[0230] In some examples, when the light intensity detection assembly 400 is installed on an electronic device, the electrical energy stored in the battery 430 can be used to power the electronic device.

[0231] The various light intensity detection assemblies provided by the embodiments of the present application can be applied to electronic devices such as watches, bracelets, mobile phones and smart glasses. As an example, the light intensity detection assembly can be assembled in the display module of an electronic device with a display screen such as a watch or a mobile phone. The following describes the setting method of the light intensity detection assembly in the display module.

[0232] As shown in FIG. 17, the display module 500 provided by the embodiments of the present application is a structural schematic diagram of a display module provided with a light intensity detection assembly. The display module 500 can include a screen cover plate 510, a light intensity detection assembly 520, a light filter 530 and a display screen 540.

[0233] The light intensity detection assembly 520 can be any one or more of the various light intensity detection assemblies provided in the above embodiments, such as one or more of the light intensity detection assembly 50, the light intensity detection assembly 100, the light intensity detection assembly 300, or the light intensity detection assembly 400, and the like.

[0234] The screen cover plate, also known as cover glass or outer screen, is located at the outermost layer of the display module. When a user operates the display module, the user can directly contact the screen cover plate. The screen cover plate can protect the inner layer structure (such as the display screen and the touch screen) of the display module. The filter, also known as the polarizing filter, can be used to modulate the light emitted by the display screen of the display module to improve the display effect of the display module. The display screen is used to convert electrical signals into visual image information to realize visual interaction between the user and the device.

[0235] Referring to FIG. 17, the screen cover plate 510, the light intensity detection assembly 520, the filter 530, and the display screen 540 are sequentially stacked in the thickness direction (z-axis direction in the figure) of the display module 500. Specifically, the light intensity detection assembly 520 is arranged between the screen cover plate 510 and the filter 520, and the display screen 540 is arranged on the side of the filter 530 away from the screen cover plate 510.

[0236] In some examples, in order to better protect the light intensity detection assembly 520 and improve the reliability and stability of the light energy conversion device structure in the light intensity detection assembly 520, a support layer 525 can be arranged in the display module 500. The support layer 525 can be arranged between the light intensity detection assembly 520 and the filter 530. The mechanical properties of the support layer 525 can meet certain requirements so that the light intensity detection assembly 520 can be supported on the support layer 525. For example, the flexural modulus of the support layer 525 can be greater than or equal to a predetermined threshold value.

[0237] The support layer 525 can be composed of a transparent material, or in other words, the light transmittance of the support layer 525 can be greater than or equal to a predetermined threshold value, so that the light emitted by the display screen 540 can pass through the support layer 525 without being blocked by the support layer 525.

[0238] In some examples, the support layer 525 can be composed of one or more of the following materials: polyimide, polyether ether ketone, polyphenylene sulfide, or polytetrafluoroethylene, and the like.

[0239] One possible case is that, as shown in FIG. 17, part of the area in the support layer 525 can be used to support the light intensity detection assembly 520, and part of the area can be vacant (i.e., not supporting the light intensity detection assembly).

[0240] In one possible case, as shown in FIG. 18, the entire area of the support layer 525 is used to carry the light intensity detection assembly 520, or in other words, the support layer 525 is only arranged below the light intensity detection assembly 520.

[0241] Referring to FIG. 17 or FIG. 18, in order to better protect the light intensity detection assembly 520, reduce the probability of damage to the light intensity detection assembly 520 during assembly and the like, and improve the production efficiency of the display module 500, an adhesive layer 515 can be further arranged between the light intensity detection assembly 520 and the screen cover plate 510 and between the light intensity detection assembly 520 and the optical filter 530. The adhesive layer 515 can be used to achieve the relative fixation of the light intensity detection assembly 520 and the screen cover plate 510, and the relative fixation between the light intensity detection assembly 520 and the optical filter 530.

[0242] In the case where the light intensity detection assembly 520 is carried on the support layer 525, the adhesive layer 515 described above can be partially arranged between the support layer 525 and the optical filter 530, for the relative fixation of the support layer 525 and the optical filter 530.

[0243] Referring to FIG. 17 and FIG. 18, the adhesive layer 515 can also be partially arranged at positions where the light intensity detection assembly 520 is at the same height and no light intensity detection assembly is arranged.

[0244] Referring to FIG. 18, in the case where the support layer 525 is only arranged below the light intensity detection assembly 520, part of the adhesive layer 515 can also be arranged at positions where the support layer 525 is at the same height and no support layer 525 is arranged.

[0245] In some examples, the adhesive layer 515 can be composed of optical transparent glue. In other words, optical transparent glue can be arranged between the light intensity detection assembly 520 and the screen cover plate 510, between the light intensity detection assembly 520 and the optical filter 530, around the light intensity detection assembly 520, and around the support layer 525.

[0246] In one possible implementation, in the production process, a piece of optical transparent glue with a prefabricated shape can be adhered to one side of the optical filter 530 facing the screen cover plate 510, another piece of optical transparent glue with a prefabricated shape can be adhered to one side of the screen cover plate 510 facing the optical filter 530, then the light energy conversion device in the light intensity detection assembly 520 is attached to any one or both of the pieces of optical transparent glue, and the screen cover plate 510 with optical transparent glue and the optical filter 530 with optical transparent glue are covered together, so as to obtain the display module 500 shown in FIG. 17 or FIG. 18.

[0247] In some examples, the light intensity detection component 520 may include one or more light energy conversion devices. The light intensity detection component 520 in the display module 500 is disposed between the screen cover 510 and the filter 530. In some scenarios, it can also be understood that the one or more light energy conversion devices in the display module 500 are disposed between the screen cover 510 and the filter 530. The light intensity detection component 520 is carried on a support layer 525. In some scenarios, it can also be understood that the one or more light energy conversion devices in the display module 500 are carried on the support layer 525.

[0248] 19 is a schematic structural diagram of another display module 600 provided with a light intensity detection component according to an embodiment of the present application. The display module 600 may include a screen cover 610, a light intensity detection component 620, a filter 630, and a display screen 640.

[0249] The light intensity detection component 620 can be any one or more of the various light intensity detection components provided in the above embodiments, for example, one or more of the light intensity detection component 50, the light intensity detection component 100, the light intensity detection component 300 or the light intensity detection component 400.

[0250] The screen cover, also known as cover glass or outer screen, is the outermost layer of the display module. Users come into direct contact with the screen cover when operating the display module, protecting the module's internal structures (such as the display and touchscreen). Filters, also known as polarizing filters, modulate the light emitted by the display module to enhance the display quality. The display screen converts electrical signals into visible image information, enabling visual interaction between the user and the device.

[0251] 19 , the screen cover 610, the light intensity detection component 620, the filter 630, and the display screen 640 are stacked in sequence along the thickness direction (z-axis direction in the figure) of the display module 600. Specifically, the light intensity detection component 620 is disposed between the screen cover 610 and the filter 620, and the display screen 640 is disposed on the side of the filter 630 away from the screen cover 610.

[0252] In some examples, to better protect the light intensity detection component 620, a support layer 625 may be provided within the display module 500. The support layer 625 may be disposed between the light intensity detection component 620 and the optical filter 630. The mechanical properties of the support layer 625 may meet certain requirements so that the light intensity detection component 620 can be supported on the support layer 625. For example, the flexural modulus of the support layer 625 may be greater than or equal to a preset threshold.

[0253] The support layer 625 can be composed of a transparent material, or in other words, the light transmittance of the support layer 625 can be greater than or equal to a preset threshold, so that the light emitted by the display screen 640 can pass through the support layer 625 without being blocked by the support layer 625.

[0254] In some examples, the support layer 625 can be composed of one or more of the following materials: polyimide, polyether ether ketone, polyphenylene sulfide, or polytetrafluoroethylene.

[0255] One possible case is that, as shown in FIG. 19, part of the area in the support layer 625 can be used to carry the light intensity detection component 620, and part of the area can be vacant (i.e., not carrying the light intensity detection component).

[0256] One possible case is that, as shown in FIG. 20, the entire area of the support layer 625 is used to carry the light intensity detection component 620, or in other words, the support layer 625 is only arranged below the light intensity detection component 620.

[0257] In order to improve the operability of the light intensity detection component 620 in the production process of the display module 600 (for example, cutting, moving, etc.), and improve the efficiency of assembly and production of the display module 600, the display module 600 can further include a film layer 616, which can be arranged between the light intensity detection component 620 and the screen cover plate 610.

[0258] In the production process, one possible implementation is to process multiple light energy conversion devices into a specific shape through cutting, splicing, etc., and then move the film-shaped, sheet-shaped or plate-shaped light energy conversion device into a clamp, and inject a material with high transparency and low viscosity such as silicone into the clamp, so that the material can be bonded with the light energy conversion device to form a sheet structure. This sheet structure has good processability, and with the help of this sheet structure, the light energy conversion device is less damaged during the moving operation in the production process. The structure formed by the material with high transparency and low viscosity such as silicone in the sheet structure is the aforementioned film layer.

[0259] In some examples, the display module 600 can further include an adhesive layer 613, which can be arranged between the aforementioned film layer 616 and the screen cover plate 610, for realizing the relative fixation of the film layer 616 and the screen cover plate 610. The adhesive layer 616 can also be arranged between the support layer 625 and the optical filter 630, for realizing the relative fixation of the support layer 625 and the optical filter 630.

[0260] In some examples, the adhesive layer 613 can be composed of optical transparent adhesive. In other words, the film 616 and the screen cover plate 510, and the support layer 625 and the optical filter 530 can be filled with optical transparent adhesive.

[0261] In some examples, the light intensity detection assembly 620 in the display module 600 can include one or more light energy conversion devices, and the light intensity detection assembly 620 in the display module 600 can be disposed between the screen cover plate 610 and the light filter 630. In some scenarios, the one or more light energy conversion devices in the display module 600 can also be understood to be disposed between the screen cover plate 610 and the light filter 630. The light intensity detection assembly 620 is carried on the support layer 625, and in some scenarios, the one or more light energy conversion devices in the display module 600 can also be understood to be carried on the support layer 625.

[0262] Taking the display module 600 shown in FIG. 19 as an example, in combination with FIG. 21, the display screen 640 can include an effective area 642 and a screen bezel 644. The effective area 642 is located in the middle region of the display screen 640, and the screen bezel 644 is located at the outer periphery of the effective area 642.

[0263] In some examples, the light intensity detection assembly 620 or the light energy conversion device in the display module 600 can be disposed without blocking the effective area 642 of the display screen 640, or in other words, the light emitted by the display screen 640 in the effective area 642 does not enter the light energy conversion device.

[0264] In some examples, the light intensity detection assembly 620 or the light energy conversion device included in the light intensity detection assembly 620 can be disposed at the outer periphery of the display module 600, and the projection of the light intensity detection assembly 620 in the plane of the display screen 640 does not fall within the effective area 642 of the display screen 640.

[0265] Referring to FIG. 21, for example, the size of the light intensity detection assembly 620 in the x-axis direction is substantially the same as the size of the screen bezel 644 of the display screen 640 in the x-axis direction, or in other words, the projection of the light intensity detection assembly 620 in the plane of the display screen 640 can coincide with the range of the screen bezel 644 of the display screen 640.

[0266] Referring to FIG. 22, for example, the size of the light intensity detection assembly 620 in the x-axis direction can be longer than the size of the screen bezel 644 of the display screen 640 in the x-axis direction, or in other words, the outside of the projection of the light intensity detection assembly 620 in the plane of the display screen 640 can be located outside the range of the screen bezel 644 of the display screen 640, or in other words, the light intensity detection assembly 620 at least partially protrudes out of the screen bezel 644 of the display screen 640. For ease of description, the part of the light intensity detection assembly 620 protruding out of the screen bezel 644 can be referred to as a protruding part.

[0267] In some examples, referring to FIG. 23, the display module 600 can further be provided with an extension part 650 in the case where the size of the light intensity detection assembly 620 in the x-axis direction is longer than the size of the screen bezel 644 of the display screen 640 in the x-axis direction. The extension part 650 can serve to support the protruding part of the light intensity detection assembly 620 to a certain extent.

[0268] One possible case is that the extension part 650 can be a separate component provided for the display module 600, or the extension part 650 can be jointly composed of other structures located on the side of the light intensity detection assembly 620 away from the screen cover plate 610 and extending to the outer periphery of the screen bezel 644 by a certain distance, for example, the extension part 650 can be jointly composed of the light filter 630 and the screen bezel 644 extending to the outside of the screen bezel 644 by a certain length.

[0269] Referring to FIG. 24, exemplarily, the size of the light intensity detection assembly 620 in the x-axis direction can be shorter than the size of the screen bezel 644 of the display screen 640 in the x-axis direction, or in other words, the projection of the light intensity detection assembly 620 in the plane where the display screen 640 is located can be located within the range of the screen bezel 644 of the display screen 640, but not coincide with the range of the screen bezel 644.

[0270] The size of the screen cover plate 610 of the display module 600 in the x-axis direction can be longer than the size of the display screen 640 in the x-axis direction, or in other words, the outer periphery of the screen cover plate 610 can extend to the outside of the display screen 640, or in other words, the projection of the display screen 640 in the plane where the screen cover plate 610 is located can fall within the range of the screen cover plate 610.

[0271] Taking the display module 600 in FIG. 19 as an example, the screen cover plate 610 can include a contact surface and an adhesive surface, the adhesive surface can be used to bond the adhesive film layer 616, and the contact surface is located on the outside of the screen cover plate 610 and is arranged opposite to the adhesive surface.

[0272] In some examples, the part of the adhesive surface of the screen cover plate 610 extending to the outside of the display screen 640 can serve as an adhesive area 611, which can be used to fixedly connect the display module 600 with the shell of the electronic device. Referring to FIG. 25, the adhesive area 611 is located at the outer periphery of the adhesive surface of the screen cover plate 610.

[0273] In one possible implementation, the light intensity detection component 620 is arranged outside the display module 600 (e.g., the Ar region shown in FIG. 25), or in other words, the light intensity detection component 620 is arranged separately from the display module 600. In this case, light needs to pass through the outer peripheral region of the screen cover plate 610 before being incident on the light intensity detection component 620. The outer peripheral region can be coated with adhesive material for bonding, which can refract or reflect the incident light. Thus, in order to enable more light to be incident on the light intensity detection component 620, the bonding region 611 shown in FIG. 25 needs to have a larger area.

[0274] Compared with the above manner, in the embodiments of this application, the light intensity detection component 620 can be arranged inside the bonding region 611 of the screen cover plate 610 (i.e., the middle region of the screen cover plate 610), or in other words, the light intensity detection component 620 can be arranged inside the display module 600. Light can be incident on the light intensity detection component 620 via the middle region of the screen cover plate 610, without occupying the outer peripheral region of the screen cover plate 610. In other words, the overall size of the screen cover plate 610 can be smaller. In addition, since the area of the middle region of the screen cover plate 610 is much larger than the area of the outer peripheral region of the screen cover plate 610, more light can be incident on the light intensity detection component 620, and the detection result of the light intensity detection component 620 for the light intensity is relatively more accurate.

[0275] In the above examples, the arrangement of the light intensity detection component in the electronic device is described by taking the arrangement of the light intensity detection component in the display module of the electronic device as an example. In some examples, the light intensity detection component can also be arranged in other regions of the electronic device other than the display module.

[0276] In some examples, as shown in FIG. 26, the electronic device can be a bracelet or a watch. In this case, the light intensity detection component can be arranged in the display module of the bracelet or the watch (i.e., the outer peripheral region of the effective region of the display screen) as described above, or can be arranged on the watchband, the watch ear, or other components of the bracelet or the watch.

[0277] Exemplarily, for a bracelet or a watch, in a case where the light intensity detection component is arranged at the periphery of the active area of the display screen in the display module, a plurality of light energy conversion devices can be arranged in the light intensity detection component. For example, referring to FIG. 27, the light intensity detection component can be provided with 4 light energy conversion devices (2701, 2702, 2703 and 2704), of which 3 light energy conversion devices (2701, 2702 and 2703) can be used to convert the light energy of sunlight into electrical energy, and 1 light energy conversion device (2704) can be used to convert the light energy of light other than ultraviolet light in sunlight into electrical energy. On this basis, the bracelet or the watch containing the light intensity detection component can simultaneously detect the intensity of sunlight and the intensity of ultraviolet light in sunlight.

[0278] In some examples, as shown in FIG. 28, the electronic device can be smart glasses, in which case the light intensity detection component can be arranged on the frame, the temple or other components of the smart glasses.

[0279] In some examples, as shown in FIG. 29, the electronic device can be a mobile phone, in a case where the mobile phone contains a "forehead" area, the light intensity detection component can be arranged at the periphery of the active area of the display screen in the display module of the mobile phone as described above, or can be arranged in the "forehead" area of the mobile phone. The "forehead" area here specifically refers to the non-display area of the top edge of the screen of the electronic device, which is located between the display screen and the frame of the electronic device, and can be used to accommodate electronic components such as cameras and earpieces. For example, the Ar area shown in FIG. 25. In some scenarios, the "forehead" area can also be referred to as a sensor accommodation area.

[0280] Based on the electronic device provided by the embodiments of the present application and provided with the light intensity detection component, the embodiments of the present application further provide a light intensity detection method. In a case where there is a network connection or no network connection, the electronic device can detect the intensity of light in the environment by using the light intensity detection component in response to the operation of the user.

[0281] S101, obtaining an operation of the user to update light intensity information.

[0282] As shown in FIG. 30, the first interface M100 of a "weather" application of an electronic device provided by the embodiments of the present application is a schematic diagram, which can be used to display the weather information of a location selected by the user, including but not limited to one or more of the following: temperature, rainfall condition, air quality condition, temperature condition at different time periods of the day or weather condition of multiple days, etc.

[0283] In some examples, the first interface M100 can also display first information M110, which can be used to indicate the light intensity information and / or the ultraviolet intensity information of the selected location. As shown in FIG. 30, the first information M110 is used to indicate that the light intensity and the ultraviolet intensity of the B-1 district in A city are weak.

[0284] For example, in response to a user's pull-down operation on the first interface M100, the electronic device can update the information displayed on the first interface M100, such as updating the first information M110. In some scenarios, the aforementioned user's pull-down operation on the first interface M100 can be regarded as an operation of updating the light intensity information.

[0285] For example, the electronic device can also periodically and automatically update the information displayed on the first interface M100, such as automatically updating the first information M110. In some scenarios, the user can set the time interval for updating the first interface M100, and in some scenarios, the operation of the electronic device automatically updating the first information M110 can also be regarded as an operation of updating the light intensity information.

[0286] It should be noted that the aforementioned time interval can be set with a default value, in other words, the user does not need to manually set the time interval, and the first information M110 and the like on the first interface M100 can also be periodically updated.

[0287] As shown in FIG. 31 is a schematic diagram of a second interface M200 of a "desktop" application of an electronic device provided by an embodiment of the present application, which can be used to display the icons of one or more applications installed on the electronic device, and can also be used to display the desktop plug-ins and the like of the applications on the electronic device.

[0288] In some examples, the second interface M200 can display a "light intensity information" plug-in M210, or second plug-in M210. The second plug-in M210 can be used to display the light intensity information of the selected location, for example, in FIG. 31, the second plug-in M210 can be used to display that the ultraviolet intensity level of the selected location is weak.

[0289] For example, the second plug-in M210 can be provided with a "data update" button M211, and in response to the user's operation of clicking the "data update" button M211, the electronic device can update the light intensity information displayed on the second plug-in M210. In some scenarios, the user's operation of clicking the "data update" button M211 can be regarded as an operation of updating the light intensity information.

[0290] In a possible implementation, the first information M110 on the first interface M100 and the information on the second plug-in M210 of the second interface M200 can be obtained from a network, for example, from an information platform of a professional meteorological service company through the network.

[0291] In another possible implementation, the first information M110 on the first interface M100 and the information on the second plug-in M210 of the second interface M200 can be obtained through a sensor inside the electronic device, for example, obtained through the component test of the light intensity detection provided in the embodiments of the present application.

[0292] In some examples, as shown in FIG. 32, a third interface M300 of a “weather” application provided in the embodiments of the present application is a schematic diagram, which can be used to display controls for selecting a data source for determining light intensity information, for example, the controls can be used to determine a data source for updating the information displayed on the first information M110 or the first plug-in M210.

[0293] For example, the third interface M300 can include a first control M310, which can be used to select a data source for the electronic device to update the information of the ultraviolet level. For example, the first control M310 can display a first option M311 and a second option M312, the first option M311 is used to indicate that the data source of the information of the ultraviolet level is a sensor (for example, the component for light intensity detection provided in the embodiments of the present application), and the second option M312 is used to indicate that the data source of the information of the ultraviolet level is network data.

[0294] For example, the third interface M300 can include a second control M320, which can be used to select a data source for the electronic device to update the information of the light intensity. For example, the second control M320 can display a first option M321 and a second option M322, the first option M321 is used to indicate that the data source of the information of the light intensity is a sensor (for example, the component for light intensity detection provided in the embodiments of the present application), and the second option M322 is used to indicate that the data source of the information of the light intensity is network data.

[0295] S102, in response to the operation of the user, calling the intensity of the light in the component test environment of the light intensity detection.

[0296] In some examples, in response to the user selecting the first option M311 in the first control M310, when detecting the operation of the user updating the light intensity information, the electronic device can update the information of the ultraviolet level by calling the sensor data; similarly, in response to the user selecting the first option M321 in the second control 320, when detecting the operation of the user updating the light intensity information, the electronic device can update the information of the light intensity by calling the sensor data.

[0297] In some examples, in response to the user selecting the second option M312 in the first control M310, when detecting the operation of the user updating the light intensity information, the electronic device can update the information of the ultraviolet level through the network; similarly, in response to the user selecting the second option M322 in the second control 320, when detecting the operation of the user updating the light intensity information, the electronic device can update the information of the light intensity through the network.

[0298] A possible case is that, in the case that the user selects the second option M312 of the aforementioned first control M310 and / or the second option M322 of the second control M320, and the electronic device is in a state without network connection, in response to the operation of the user updating the light intensity information, the electronic device can display a prompt control M400 as shown in FIG. 33, which can be used to prompt that the light intensity information cannot be updated through the network at present, and the user can update the light intensity information through the sensor.

[0299] For example, the prompt control M400 can display the prompt information: “Cannot update the UV level information through the network, do you want to update through the sensor?” In response to the confirmation operation of the user, the electronic device can call the sensor to update the UV level information. In response to the cancel operation of the user, the electronic device can prompt that the UV level information will be automatically updated in the case that the network connection is restored.

[0300] S103, display a user interface containing updated light intensity information.

[0301] For example, in response to the user's pull-down operation on the first interface M100, the electronic device can update the first information M110 displayed on the first interface M100, for example, the light intensity in the first information M110 can be updated from “weak” to “weakest”.

[0302] For example, in response to the user's operation of clicking the “data update” button M211 of the first plug-in M210 of the second interface M200, the electronic device can update the information of the ultraviolet intensity displayed on the second plug-in M210, for example, the ultraviolet intensity displayed on the second plug-in M210 can be updated from “weakest” to “stronger”.
