Unless otherwise stated, "a plurality of" means two or more.

[0137] Before explaining the technical solution of this application, the inventive concept of this application will be explained first.

[0138] Technological innovation has brought about a transformation in lifestyles. With the rapid development of technology, electronic devices such as smartphones, tablets, and smartwatches have become indispensable parts of daily life, influencing people's entertainment, work, and learning methods. However, the normal operation of electronic devices cannot be separated from a power supply. Therefore, users have placed higher demands on the battery life and charging convenience of electronic devices. Furthermore, with the upgrading of electronic devices, users are increasingly emphasizing their thinness and miniaturization. In the pursuit of portability and slim design, many electronic devices have adopted smaller batteries and more compact internal spaces, which directly affects their battery life.

[0139] To address the battery life issue of electronic devices, the inventors attempted to improve battery life by adding photoelectric converters to the non-display areas of the devices. These converters would transform solar energy into electrical energy for the device's use or storage in a battery, thus achieving a balance between miniaturization and extended battery life. However, while this approach improves battery life to some extent, the front of the device is the display panel. To avoid interfering with the display, the photoelectric converters must be placed in the non-display areas on the front or on the back of the device. This results in low solar energy utilization and a less than ideal improvement in battery life.

[0140] In view of this, embodiments of this application provide a photoelectric conversion module, a display component, an electronic device, and a power management method. The display component has an optical waveguide module on the display panel. The optical waveguide module transmits external light to the photoelectric conversion component, which then converts the light energy into electrical energy. This not only avoids affecting the display panel's display but also collects light energy and converts it into electrical energy to power the electronic device, thereby improving the electronic device's battery life. This allows for miniaturization of the electronic device while maintaining its battery life.

[0141] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0142] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the display component provided in an embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of the structure of the display components in terms of the direction of external light transmission; Figure 3This is a schematic diagram of the structure of a display component (with the photoelectric conversion element disposed on the side of the optical waveguide module facing away from the display panel) provided in an embodiment of this application. In a first aspect, this application discloses a display component 100, which includes a display panel 1, a photoelectric conversion element 2, and an optical waveguide module 3. The photoelectric conversion element 2 is disposed on the periphery of the display panel 1 and is configured to convert light energy into electrical energy. The optical waveguide module 3 is disposed on the display panel 1 and is configured to conduct external light to the photoelectric conversion element 2.

[0143] It should be noted that, in order to facilitate the illustration of the optical path in the optical waveguide module, the optical waveguide module is not filled in any of the figures in this application.

[0144] The display component 100 provided in this application embodiment can transmit external light to the photoelectric converter 2 via the optical waveguide module 3 on the display panel 1, and the photoelectric converter 2 converts light energy into electrical energy. On the one hand, since the optical waveguide module 3 is a transparent optical element with high light transmittance, it can avoid affecting the display of the display panel 1, thereby avoiding affecting the use function of the electronic device 200. On the other hand, by collecting light energy and converting it into electrical energy to power the electronic device 200, it is beneficial to improve the battery life of the electronic device 200. Thus, it is possible to achieve miniaturization of the electronic device 200 while also ensuring its battery life.

[0145] Understandably, because the light transmission path of display panel 1 when displaying an image is different from the light transmission path of photoelectric converter 2 when transmitting external light, the working states of photoelectric converter 2 and display panel 1 do not affect each other. That is, the display state and power generation state of display component 100 can be carried out simultaneously, or one of them can be carried out independently.

[0146] It is understandable that the above display state refers to the state of the display panel 1 displaying the screen; the above power generation state refers to the state in which the optical waveguide module 3 transmits external light to the photoelectric converter 2, and the photoelectric converter 2 converts light energy into electrical energy.

[0147] Optionally, the optical waveguide module 3 transmits external light to the photoelectric converter 2 by means of, for example, reflection, that is, the optical waveguide module 3 reflects external light to the photoelectric converter 2. Alternatively, it can also transmit external light by means of, for example, refraction, that is, the optical waveguide module 3 refracts external light to the photoelectric converter 2.

[0148] Optionally, the aforementioned photoelectric conversion element 2 may include solar cells, organic photovoltaic cells, etc., and this embodiment does not limit this.

[0149] For example, the photoelectric conversion element 2 includes a solar cell. Because solar cells have a long lifespan and low maintenance requirements, the photoelectric conversion element 2 also has a long lifespan, thereby improving the lifespan of the display assembly 100 and reducing maintenance costs. As another example, the photoelectric conversion element 2 includes an organic photovoltaic cell. Because organic photovoltaic cells are flexible, the photoelectric conversion element 2 is malleable, allowing its shape to be freely changed to meet the needs of the display assembly 100.

[0150] Optionally, when the photoelectric conversion element 2 includes a solar cell, the material of the photoelectric conversion element 2 may include monocrystalline silicon, perovskite, or gallium arsenide, etc., and this embodiment does not limit this.

[0151] For example, the photoelectric converter 2 can be made of monocrystalline silicon. Monocrystalline silicon typically has high conversion efficiency, good stability, and strong durability, which helps improve the utilization rate of external light transmitted by the optical waveguide module 3 and extends the lifespan of the photoelectric converter 2, thus improving the lifespan of the display component 100. Alternatively, the photoelectric converter 2 can be made of perovskite. Perovskite has high efficiency potential, low cost, and lightweight properties, which further improves the utilization rate of external light transmitted by the optical waveguide module 3, reduces the production cost of the display component 100, and allows it to be made into a flexible material, facilitating various innovative applications. Another example is the photoelectric converter 2 made of gallium arsenide. Gallium arsenide has extremely high efficiency and light weight, allowing the photoelectric converter 2 to maintain high efficiency even under low light conditions and reducing the overall weight of the display component 100.

[0152] Optionally, when the photoelectric conversion element 2 includes an organic photovoltaic cell, the material of the photoelectric conversion element 2 is an organic photovoltaic material, which can be an organic polymer, such as poly(3-hexene), poly(3,4-ethylenedioxythiophene), etc.; or it can be an organic small molecule, such as fullerene derivatives, organic dyes, etc. This embodiment does not limit this.

[0153] For example, the photoelectric conversion element 2 can be made of an organic polymer. Due to the flexibility, low-temperature processing, and tunable spectral absorption of organic polymers, the photoelectric conversion element 2 can be manufactured into a thin and lightweight photovoltaic module. It can also be processed at lower temperatures, which is beneficial for energy conservation and environmental protection, and reduces the production cost of the display module 100. Furthermore, by designing the chemical structure of the organic polymer, the absorption of specific wavelengths of light by the photoelectric conversion element 2 can be optimized, thus improving the photoelectric conversion efficiency. As another example, the photoelectric conversion element 2 can be made of small organic molecules. Due to the good electronic conductivity, ease of combination, and solubility of small organic molecules, the photoelectric conversion element 2 can achieve highly efficient energy conversion, thereby improving its photoelectric conversion efficiency. It can also combine small organic molecules with other materials (such as nanoparticles or polymers) to form composite materials, further improving the photoelectric conversion efficiency of the photoelectric conversion element 2. Simultaneously, by utilizing the solubility of small organic molecules, the photoelectric conversion element 2 can be prepared by dissolving the small organic molecules and then using methods such as spraying or printing, which helps reduce the manufacturing cost of the display module 100.

[0154] Optionally, the material of the photoelectric conversion element 2 can also be a hybrid material such as perovskite-organic hybrid material or gallium arsenide-organic hybrid material, and this embodiment does not limit this.

[0155] It is understood that the display panel 1 includes a display area 11 and a non-display area 12 surrounding the display area 11. The display area 11 is used to display images, text or video content, and the non-display area 12 is used to provide structural support for the display area 11 and provide certain protection.

[0156] Optionally, the optical waveguide module 3 is located in the display area 11.

[0157] Optionally, the optical waveguide module 3 is located in the non-display area 12.

[0158] Optionally, such as Figures 1 to 3 As shown, the optical waveguide module 3 covers both the display area 11 and the non-display area 12.

[0159] The aforementioned method of setting the optical waveguide module 3 in the display area 11 and the non-display area 12 has two advantages. First, the setting of the optical waveguide module 3 will not affect the display panel 1, regardless of whether it is set in the display area 11 or the non-display area 12, thus avoiding affecting the functionality of the electronic device 200. Second, by collecting light energy through the optical waveguide module 3 and converting the light energy into electrical energy by the photoelectric converter 2 to power the electronic device 200, it is beneficial to improve the battery life of the electronic device 200. Thus, it is possible to achieve the miniaturization design of the electronic device 200 while also ensuring its battery life.

[0160] It is worth noting that by simultaneously covering the display area 11 and the non-display area 12 with the optical waveguide module 3, the area of ​​the optical waveguide module 3 that collects external light can be increased, thereby increasing the light energy transmitted to the photoelectric converter 2, which is beneficial to increasing the amount of electricity converted by the photoelectric converter 2, and thus further improving the battery life of the electronic device 200.

[0161] Therefore, it can be seen that the use of optical waveguide module 3 can greatly improve the battery life of electronic devices.

[0162] It is understood that the projection of the photoelectric conversion element 2 onto the plane of the display panel 1 can be located within or outside the non-display area 12, and this embodiment does not limit this. For example, the projection of the photoelectric conversion element 2 onto the plane of the display panel 1 can be located within the non-display area 12. That is, the photoelectric conversion element 2 can be positioned corresponding to the non-display area 12 of the display panel 1, thereby eliminating the need to position the photoelectric conversion element 2 in any other location besides the display area 11 and the non-display area 12, which is beneficial for reducing the width of the display component 100.

[0163] Optionally, when the photoelectric conversion element 2 is located in the non-display area 12, the photoelectric conversion element 2 can be disposed outside the display panel 1 or inside the display panel 1; this embodiment does not limit this. For example, as shown... Figures 1 to 2 As shown, the photoelectric conversion element 2 is located in the non-display area 12, and the photoelectric conversion element 2 is located inside the display panel 1. By placing the photoelectric conversion element 2 inside the display panel 1, the thickness of the display assembly 100 can be reduced, thereby making the structure of the display assembly 100 more compact.

[0164] For example, when the photoelectric converter 2 is disposed inside the display panel 1, the photoelectric converter 2 can be disposed in the clearance position by, for example, setting a clearance position inside the display panel 1, while the cover plate of the display panel 1 covers the photoelectric converter 2.

[0165] Optionally, such as Figures 1 to 2 As shown, the photoelectric conversion component 2 is disposed on the side of the optical waveguide module 3 near the display panel 1.

[0166] Optionally, such as Figure 3 As shown, the photoelectric conversion component 2 is disposed on the side of the optical waveguide module 3 away from the display panel 1.

Optionally, as Figure 5 As shown in (a) and (c), the photoelectric conversion element 2 is disposed on the side of the optical waveguide module 3 near the display panel 1 and on the side surface of the optical waveguide module 3.

[0169] Optionally, such as Figure 5 As shown in (b), the photoelectric conversion element 2 is disposed on the side of the optical waveguide module 3 away from the display panel 1 and on the side surface of the optical waveguide module 3.

[0170] Please combine Figure 6 , Figure 6 This is a schematic diagram of the structure of a display component (with photoelectric conversion element disposed on the side of the optical waveguide module close to the display panel and the side away from the display panel) provided in an embodiment of this application. Optionally, the photoelectric conversion element 2 is disposed on the side of the optical waveguide module 3 close to the display panel 1 and the side of the optical waveguide module 3 away from the display panel 1.

[0171] Please combine Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the display component (the photoelectric conversion element is disposed on the side of the optical waveguide module near the display panel, the side surface, and the side away from the display panel) provided in the embodiments of this application; Figure 8 This is a schematic diagram of the structure of the display component (coupling unit includes two) provided in the embodiments of this application. Optionally, the photoelectric conversion element 2 is disposed on the side of the optical waveguide module 3 near the display panel 1, the side surface of the optical waveguide module 3, and the side of the optical waveguide module 3 away from the display panel 1.

[0172] These methods enable the display component 100 to adapt to the application requirements of different electronic devices 200, thereby improving the applicability of the display component 100. Furthermore, by simultaneously placing the photoelectric converter 2 on the side surface of the optical waveguide module 3, on the side facing away from the display panel 1, and on the side close to the display panel 1, the photoelectric converter 2 can receive light transmitted from the optical waveguide module 3 to the side surface. This increases the area of ​​the photoelectric converter 2 that receives external light transmitted by the optical waveguide module 3, thereby further increasing the amount of electricity converted by the photoelectric converter 2, and consequently further improving the battery life of the electronic device 200.

[0173] It is understood that in the above embodiments, the photoelectric conversion element 2 includes one or more.

[0174] Optionally, such as Figure 5As shown in (a) and (c), the photoelectric conversion element 2 includes two components. One of the photoelectric conversion elements 2 is disposed on the side surface of the waveguide module 3, and the other photoelectric conversion element 2 is disposed on the side of the optical waveguide module 3 near the display panel 1.

[0175] Optionally, such as Figure 5 As shown in (b), the photoelectric conversion element 2 includes two components.

[0176] Optionally, such as Figure 6 As shown, the photoelectric conversion element 2 includes two components. One of the photoelectric conversion elements 2 is located on the side of the optical waveguide module 3 away from the display panel 1, and the other photoelectric conversion element 2 is located on the side of the optical waveguide module 3 close to the display panel 1.

[0177] Optionally, such as Figure 7 and Figure 8 As shown, the photoelectric conversion element 2 includes three components, which are respectively disposed on the side surface of the waveguide module 3, the side of the waveguide module 3 away from the display panel 1, and the side of the waveguide module 3 close to the display panel 1.

[0178] It is understood that when there are multiple photoelectric conversion elements 2, the multiple photoelectric conversion elements 2 can be arranged at intervals or connected to each other. This embodiment does not limit this.

[0179] Please see Figures 9 to 11 , Figure 9 This is a schematic diagram of the structure of the display component (photoelectric conversion element including a first part and a second part) provided in the embodiments of this application; Figure 10 This is a schematic diagram of the structure of a display component (photoelectric conversion element including a first part, a second part and a third part) provided in an embodiment of this application; Figure 11 This is a schematic diagram of the structure of a display component (the photoelectric conversion element includes a first part and a second part, and the coupling unit includes two parts) provided in the embodiments of this application. It can be understood that when the photoelectric conversion element 2 is provided on the side surface of the optical waveguide module 3, and when the photoelectric conversion element 2 is provided on at least one side of the optical waveguide module 3 away from the display panel 1 and the side of the optical waveguide module 3 close to the display panel 1, the photoelectric conversion element 2 may also include one part, which will be described in detail below.

[0180] Optionally, such as Figure 9As shown in (a) and (c), the photoelectric conversion element 2 includes a first part 21 and a second part 22 connected to the first part 21. The first part 21 is located on the side of the optical waveguide module 3 near the display panel 1, and the second part 22 is located on the side surface of the optical waveguide module 3. That is, the photoelectric conversion element 2 is L-shaped and disposed on the side of the optical waveguide module 3 near the display panel 1 and on the side surface of the optical waveguide module 3.

[0181] Optionally, such as Figure 9 As shown in (b), the photoelectric conversion element 2 includes a first part 21 and a second part 22 connected to the first part 21. The first part 21 is located on the side of the optical waveguide module 3 facing away from the display panel 1, and the second part 22 is located on the side surface of the optical waveguide module 3. That is, the photoelectric conversion element 2 is L-shaped and disposed on the side of the optical waveguide module 3 facing away from the display panel 1 and on the side surface of the optical waveguide module 3.

[0182] Optionally, such as Figure 10 and Figure 11 As shown, the photoelectric conversion component 2 includes a first part 21, a second part 22, and a third part 23 connected in sequence. The first part 21 is located on the side of the optical waveguide module 3 facing away from the display panel 1, the second part 22 is located on the side surface of the optical waveguide module 3, and the third part 23 is located on the side of the optical waveguide module 3 close to the display panel 1. That is, the photoelectric conversion component 2 is arranged in a U-shape on the side of the optical waveguide module 3 close to the display panel 1, the side surface of the optical waveguide module 3, and the side of the optical waveguide module 3 facing away from the display panel 1.

[0183] The second part 22 on the photoelectric converter 2 can receive light transmitted to the side surface from the optical waveguide module 3, which helps to increase the area of ​​the photoelectric converter 2 that receives external light transmitted by the optical waveguide module 3, thereby further increasing the amount of electricity converted by the photoelectric converter 2, and thus further improving the battery life of the electronic device 200. In addition, the integrated arrangement of the first part 21, the second part 22 and the third part 23 facilitates the assembly of the display component 100 and simplifies the assembly difficulty of the display component 100.

[0184] Some alternative implementations, such as Figure 4As shown, the optical waveguide module 3 includes a coupling unit 31 and an optical waveguide 32. The coupling unit 31 is configured to conduct external light to the optical waveguide 32, which is disposed on the display panel 1. The optical waveguide 32 is configured to conduct the external light transmitted by the coupling unit 31 to the photoelectric converter 2. By collecting external light through the coupling unit 31, the process of external light passing directly through the optical waveguide 32 and failing to be conducted to the photoelectric converter 2 for utilization is avoided. Simultaneously, the process of external light being conducted to the photoelectric converter 2 is achieved through the optical waveguide 32. Furthermore, the optical waveguide 32 reduces energy loss during the conduction of external light, which is beneficial for efficient conduction of external light and thus improves the conversion efficiency of the display component 100.

[0185] Some alternative implementations, such as Figures 9 to 11 As shown, the optical waveguide module 3 also includes a coupling unit 33, which is configured to transmit external light transmitted by the optical waveguide 32 to the photoelectric converter 2. Through the optical waveguide 32 and the coupling unit 33, the process of transmitting external light collected by the coupling unit 31 to the photoelectric converter 2 is realized. Furthermore, the coupling unit 33 allows external light to be transmitted from the side of the optical waveguide 32 closer to or away from the display panel 1 to the photoelectric converter 2, which improves the flexibility of the photoelectric converter 2's configuration and thus enhances the applicability of the display assembly 100.

[0186] Optionally, such as Figures 9 to 11 As shown, along the direction of external light transmission, the coupling unit 31 is positioned upstream of the optical waveguide 32, and the optical waveguide 32 is positioned upstream of the coupling unit 33. By sequentially arranging the coupling unit 31, optical waveguide 32, and coupling unit 33 along the direction of external light transmission, external light can be transmitted between the coupling unit 31, optical waveguide 32, and coupling unit 33. This facilitates smooth transmission of external light between different components, thereby optimizing the overall performance of the display component 100. Furthermore, this method effectively avoids light loss and scattering during transmission, thereby improving the transmission efficiency and signal quality of external light.

[0187] Optionally, such as Figure 10 and Figure 11 As shown, when the photoelectric conversion element 2 is disposed on the side of the optical waveguide 32 close to the display panel 1 and the side of the optical waveguide 32 away from the display panel 1, the coupling unit 33 may include one or more. For example, as Figure 10 As shown, the coupling unit 33 includes one unit. The coupling unit 33 is disposed on the side of the optical waveguide 32 near the display panel 1 or on the side of the optical waveguide 32 away from the display panel 1, corresponding to the photoelectric conversion element 2. The coupling unit 33 is located between the photoelectric conversion element 2 and the optical waveguide 32. For example, as... Figure 11As shown, the coupling unit 33 includes two units. The two coupling units 33 are respectively disposed on the side of the optical waveguide 32 close to the display panel 1 and the side of the optical waveguide 32 away from the display panel 1, corresponding to the photoelectric conversion element 2. Both coupling units 33 are located between the photoelectric conversion element 2 and the optical waveguide 32.

[0188] The specific configurations of the coupling-in unit 31, optical waveguide 32, and coupling-out unit 33 will be described in detail below with reference to the accompanying drawings. It should be noted that the specific configurations of the photoelectric conversion element 2 described above apply to the specific configurations of the coupling-in unit 31, optical waveguide 32, and coupling-out unit 33 described below. For ease of explanation, the accompanying drawings below will show an example where the photoelectric conversion element 2 is located on the side of the optical waveguide module 3 closest to the display panel 1.

[0189] Please combine Figures 12 to 14 , Figure 12 This is a schematic diagram of the structure of the display component (the first diffraction grating is disposed on the side of the optical waveguide module away from the display panel) provided in the embodiment of this application; Figure 13 This is a schematic diagram of the structure of the display component (the first diffraction grating is disposed between the optical waveguide and the display panel) provided in the embodiment of this application; Figure 14 This is a schematic diagram of the display component (coupling unit includes a semi-transparent and semi-reflective structure) provided in an embodiment of this application. To improve the efficiency of light transmission from the coupling unit 33 to the photoelectric conversion element 2, the positional relationship between the coupling unit 33 and the photoelectric conversion element 2 is considered. Specifically, as shown... Figures 12 to 14 As shown, the coupling unit 33 and the photoelectric conversion element 2 are positioned close to the edge of the optical waveguide 32. This effectively reduces light reflection at the interface between the optical waveguide 32 and the air, thereby improving light transmission efficiency. Furthermore, by placing the photoelectric conversion element 2 close to the edge of the optical waveguide 32, it can be better matched to the optical waveguide 32, thus improving the coupling efficiency between the optical waveguide module 3 and the photoelectric conversion element 2.

[0190] Optionally, the projection of the coupling unit 33 onto the surface of the optical waveguide 32 is located within the projection range of the photoelectric converter 2 onto the surface of the optical waveguide 32. This prevents external light transmitted by the coupling unit 33 from falling outside the photoelectric converter 2, which improves light transmission efficiency, allows the photoelectric converter 2 to receive more light energy, and thus increases the amount of electricity converted by the photoelectric converter 2, further enhancing the battery life of the electronic device 200.

[0191] Optionally, when the display panel 1 includes a non-display area 12, the projection of the coupling unit 33 onto the display panel 1 is located in the non-display area 12. This avoids interference from the optical structure of the coupling unit 33 on the content displayed on the display panel 1, thereby improving user experience and visual effects. Furthermore, by effectively utilizing the non-display area 12, the overall design of the display assembly 100 becomes more compact, reducing its footprint on the display area 11 and helping to maintain the clarity and aesthetics of the display panel 1. Moreover, placing the coupling unit 33 in the non-display area 12 reduces interference from the display panel 1's optics on the light emitted by the coupling unit 33, improving light transmission efficiency and thus increasing the power conversion capacity of the photoelectric converter 2, further enhancing the battery life of the electronic device 200.

[0192] Optionally, the coupling unit 33 can be located outside or inside the display panel 1; this embodiment does not limit this. For example, as shown... Figure 12 As shown in (b), the coupling unit 33 is located inside the display panel 1, thereby reducing the thickness of the display component 100 and making the structure of the display component 100 more compact.

[0193] For example, when the coupling unit 33 is disposed inside the display panel 1, the coupling unit 33 and the photoelectric conversion element 2 can be stacked along the thickness direction of the display panel 1. For example, the coupling unit 33 can be disposed above the photoelectric conversion element 2, or the coupling unit 33 can be disposed below the photoelectric conversion element 2.

[0194] It is understood that the coupling unit 31 may include, for example, a first diffraction grating structure 311 or a semi-transparent and semi-reflective structure 312, etc., and this embodiment does not limit it.

[0195] Optionally, such as Figure 12 As shown, the coupling unit 31 includes a first diffraction grating structure 311, which is disposed on the side of the optical waveguide 32 away from the display panel 1.

[0196] Optionally, such as Figure 13 As shown, the coupling unit 31 includes a first diffraction grating structure 311, which is disposed between the optical waveguide 32 and the display panel 1.

[0197] Optionally, such as Figure 14 As shown, the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, which is disposed within the optical waveguide 32.

[0198] The aforementioned configuration of the coupling unit 31 as either a first diffraction grating structure 311 or a semi-transparent, semi-reflective structure 312 allows for the reflection of external light, enabling it to enter the optical waveguide 32 at a suitable incident angle, thereby achieving the purpose of collecting external light. Simultaneously, by adjusting the transmittance and reflectivity of the first diffraction grating structure 311 or the semi-transparent, semi-reflective structure 312, the transmission characteristics of external light entering the optical waveguide 32 can be more flexibly controlled, thus facilitating better realization of the optical performance of the coupling unit 31. Furthermore, placing the first diffraction grating structure 311 on the side of the optical waveguide 32 facing away from the display panel 1 allows external light to be directly coupled into the optical waveguide 32 through the first diffraction grating structure 311. This helps reduce energy loss of external light and avoids interference from the display panel 1 on the optical coupling, thereby improving the transmission efficiency of the coupling unit 31 for external light and further enhancing the power conversion of the photoelectric converter 2, ultimately improving the battery life of the electronic device 200. Furthermore, by placing the semi-transparent and semi-reflective structure 312 within the optical waveguide 32, the optical waveguide module 3 can be efficiently integrated, which helps to simplify the overall layout of the display component 100.

[0199] Correspondingly, such as Figures 12 to 14 As shown, the coupling unit 33 may include, for example, a second diffraction grating structure 331 or a reflection structure 332.

[0200] Optionally, such as Figure 12 (a) Figure 13 (a) and Figure 14 As shown in (a), the coupling unit 33 includes a second diffraction grating structure 331, which is disposed on the side of the optical waveguide 32 away from the display panel 1, and the second diffraction grating structure 331 is disposed corresponding to the photoelectric conversion element 2.

[0201] Optionally, such as Figure 12 (b) Figure 13 (b) and Figure 14 As shown in (b), the coupling unit 33 includes a second diffraction grating structure 331, which is disposed on the side of the optical waveguide 32 near the display panel 1, and the second diffraction grating structure 331 is disposed corresponding to the photoelectric conversion element 2.

[0202] Optionally, such as Figure 12 (c) Figure 13 (c) and Figure 14 As shown in (c), the coupling unit 33 includes a reflection structure 332, which is disposed within the optical waveguide 32 and corresponds to the photoelectric conversion unit 2.

[0203] By configuring the coupling unit 33 as either a second diffraction grating structure 331 or a reflection structure 332, light rays in the optical waveguide 32 can be reflected, thereby transmitting the light rays from the optical waveguide 32 to the photoelectric converter 2 to convert light energy into electrical energy. Simultaneously, by placing the second diffraction grating structure 331 on the optical waveguide 32, light rays can be effectively extracted from the optical waveguide 32, reducing light loss within the optical waveguide 32 and enabling more efficient coupling of light rays. Furthermore, through the diffraction effect, the propagation direction of the light rays can be adjusted, allowing them to better enter the photoelectric converter 2 and improving the conversion efficiency of the photoelectric converter 2. In addition, by placing the reflection structure 332 corresponding to the photoelectric converter 2 within the optical waveguide 32, light rays are reflected internally within the optical waveguide 32, effectively reducing interference from the external environment on light transmission, thus improving the system stability and reliability of the optical waveguide module 3.

[0204] Some alternative implementations, such as Figures 12 to 14 As shown, when the coupling unit 31 is the first diffraction grating, the coupling unit 33 can be the second diffraction grating structure 331 or the reflection structure 332.

[0205] For example, an exemplary one, such as Figure 12 As shown in (a), when the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 away from the display panel 1, the coupling unit 33 includes a second diffraction grating structure 331. The second diffraction grating structure 331 is disposed on the side of the optical waveguide 32 away from the display panel 1, corresponding to the photoelectric conversion element 2, and the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed adjacent to each other.

[0206] Another example, such as Figure 12 As shown in (b), when the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 away from the display panel 1, the coupling unit 33 includes a second diffraction grating structure 331. The second diffraction grating structure 331 is disposed on the side of the optical waveguide 32 away from the first diffraction grating structure 311, and the second diffraction grating structure 331 is disposed corresponding to the photoelectric conversion element 2.

[0207] Another example, such as Figure 12 As shown in (c), when the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 away from the display panel 1, the coupling unit 33 includes a reflection structure 332, which is disposed in the optical waveguide 32 and is disposed corresponding to the photoelectric conversion unit 2.

[0208] Another example, such as Figure 13As shown in (a), when the first diffraction grating structure 311 is disposed between the optical waveguide 32 and the display panel 1, the coupling unit 33 includes a second diffraction grating structure 331. The second diffraction grating structure 331 is disposed on the side of the optical waveguide 32 away from the first diffraction grating structure 311, and the second diffraction grating structure 331 is disposed corresponding to the photoelectric conversion element 2.

[0209] Another example, such as Figure 13 As shown in (b), when the first diffraction grating structure 311 is disposed between the optical waveguide 32 and the display panel 1, the coupling unit 33 includes a second diffraction grating structure 331. The second diffraction grating structure 331 corresponds to the photoelectric conversion element 2 disposed on the side of the optical waveguide 32 close to the display panel 1, and the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed adjacent to each other.

[0210] Another example, such as Figure 13 As shown in (c), when the first diffraction grating structure 311 is disposed between the optical waveguide 32 and the display panel 1, the coupling unit 33 includes a reflection structure 332, which is disposed within the optical waveguide 32 and corresponds to the photoelectric conversion unit 2.

[0211] Other alternative implementations, such as Figure 14 As shown, when the coupling unit 31 is a semi-transparent, semi-reflective structure 312, the coupling unit 33 can also be a second diffraction grating structure 331 or a reflection structure 332. For example, an exemplary design... Figure 14 As shown in (a), when the coupling unit 31 is a semi-transparent and semi-reflective structure 312, the coupling unit 33 includes a second diffraction grating structure 331, and the second diffraction grating structure 331 is disposed on the side of the optical waveguide 32 away from the display panel 1, corresponding to the photoelectric conversion element 2.

[0212] Another example, such as Figure 14 As shown in (b), when the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, the coupling unit 33 includes a second diffraction grating structure 331, and the second diffraction grating structure 331 is disposed on the side of the optical waveguide 32 close to the display panel 1, corresponding to the photoelectric conversion element 2.

[0213] Another example, such as Figure 14 As shown in (c), when the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, the coupling unit 33 includes a reflective structure 332. The reflective structure 332 is disposed within the corresponding photoelectric conversion element 2 disposed within the optical waveguide element 32, and the reflective structure 332 is located on the periphery of the semi-transparent and semi-reflective structure 312.

[0214] Through various structural combinations of the coupling unit 31 and the coupling unit 33, the optical waveguide module 3 possesses high flexibility, optimized performance, and compatibility. This allows the optical waveguide module 3 to adapt to different types of display panels 1 and photoelectric conversion requirements by adjusting different structural combinations of the coupling unit 31 and the coupling unit 33. Simultaneously, by selecting the most suitable combination, the light transmission efficiency and photoelectric conversion efficiency can be effectively improved. Furthermore, these various structural combinations enable the display component 100 to be well-matched with photoelectric conversion devices 2 of different specifications and types, which is beneficial for improving the adaptability and compatibility of the display component 100.

[0215] In some optional embodiments, when both the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on the same side of the optical waveguide 32, the second diffraction grating structure 331 is disposed on the periphery of the first diffraction grating structure 311. That is, when both the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on the side of the optical waveguide 32 away from the display panel 1, the second diffraction grating structure 331 is disposed on the periphery of the first diffraction grating structure 311. Alternatively, when both the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on the side of the optical waveguide 32 close to the display panel 1, the second diffraction grating structure 331 is disposed on the periphery of the first diffraction grating structure 311.

[0216] In other optional embodiments, when the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on opposite sides of the optical waveguide 32, the first diffraction grating structure 311 covers the surface of the optical waveguide 32. That is, when the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 away from the display panel 1, and the second diffraction grating structure 331 is disposed on the other side of the optical waveguide 32 away from the first diffraction grating structure 311, the first diffraction grating structure 311 covers the surface of the optical waveguide 32. Alternatively, when the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 closer to the display panel 1, and the second diffraction grating structure 331 is disposed on the other side of the optical waveguide 32 away from the first diffraction grating structure 311, the first diffraction grating structure 311 covers the surface of the optical waveguide 32.

[0217] In some alternative embodiments, when the coupling unit 31 includes a first diffraction grating structure 311 and the coupling unit 33 includes a reflection structure 332, the first diffraction grating structure 311 covers the surface of the optical waveguide 32. That is, when the coupling unit 33 includes a reflection structure 332, the first diffraction grating structure 311 can cover the surface of the optical waveguide 32 opposite to the display panel 1, or it can cover the surface of the optical waveguide 32 close to the display panel 1. For example, when the coupling unit 33 includes a reflection structure 332 and the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 opposite to the display panel 1, the first diffraction grating structure 311 covers the surface of the optical waveguide 32. Alternatively, when the coupling unit 33 includes a reflection structure 332 and the first diffraction grating structure 311 is disposed on the side of the optical waveguide 32 close to the display panel 1, the first diffraction grating structure 311 covers the surface of the optical waveguide 32.

[0218] Through the above-mentioned various implementation methods, the first diffraction grating structure 311 can have a larger area, thereby effectively increasing the area of ​​the coupling unit 31 that collects external light, which in turn helps to improve the power conversion of the photoelectric conversion element 2 and further improve the battery life of the electronic device 200.

[0219] Optionally, when the coupling unit 31 includes a first diffraction grating structure 311, the first diffraction grating structure 311 includes, but is not limited to, a surface relief grating or a volume holographic grating.

[0220] Optionally, when the coupling unit 33 includes a second diffraction grating structure 331, the second diffraction grating structure 331 includes, but is not limited to, a surface relief grating or a volume holographic grating.

[0221] Optionally, when the coupling unit 31 includes a first diffraction grating structure 311, the first diffraction grating structure 311 includes, but is not limited to, a surface relief grating or a volume holographic grating, and when the coupling unit 33 includes a second diffraction grating structure 331, the second diffraction grating structure 331 includes, but is not limited to, a surface relief grating or a volume holographic grating. That is, the first diffraction grating structure 311 may include a surface relief grating, and the second diffraction grating structure 331 may include a surface relief grating. Alternatively, the first diffraction grating structure 311 may include a surface relief grating, and the second diffraction grating structure 331 may include a volume holographic grating. Alternatively, the first diffraction grating structure 311 may include a volume holographic grating, and the second diffraction grating structure 331 may include a surface relief grating. Alternatively, the first diffraction grating structure 311 may include a volume holographic grating, and the second diffraction grating structure 331 may include a volume holographic grating.

[0222] By using the first diffraction grating structure 311 and the second diffraction grating structure 331 as surface relief gratings, the manufacturing process of the coupling unit 31 can be simplified, making it relatively easy to manufacture and integrate onto the optical waveguide 32. Furthermore, the coupling angle of the light can be optimized by adjusting the structural parameters of the grating, thereby achieving efficient optical coupling, reducing light energy loss, and improving the power conversion efficiency of the photoelectric converter 2, thus enhancing the battery life of the electronic device 200. Alternatively, by using the first diffraction grating structure 311 and the second diffraction grating structure 331 as volume holographic gratings, multiple wavelengths of external light can be coupled simultaneously, thereby improving the transmission efficiency of external light. Moreover, due to the low-loss characteristics of volume holographic gratings, the scattering and absorption losses of the first diffraction grating structure 311 and the second diffraction grating structure 331 during the transmission of external light can be reduced, further improving the power conversion efficiency of the photoelectric converter 2 and thus enhancing the battery life of the electronic device 200.

[0223] Optionally, the aforementioned semi-transparent and semi-reflective structure 312 can be a semi-transparent and semi-reflective mirror, a dichroic mirror, etc., and this embodiment is not limited to this. As an example, the semi-transparent and semi-reflective structure 312 is a semi-transparent and semi-reflective mirror. The semi-transparent and semi-reflective mirror allows the display light of the display panel 1 to pass through the optical waveguide 32, and also couples external light into the optical waveguide 32. Furthermore, by adjusting the transmittance and reflectance of the semi-transparent and semi-reflective mirror, the light intensity of the transmitted light can be precisely controlled, which is beneficial to improving the quality of the transmitted light, thereby improving the conversion efficiency of the photoelectric converter 2, and thus improving the battery life of the electronic device 200. Another example is that the semi-transparent and semi-reflective structure 312 is a dichroic mirror. The dichroic mirror can selectively reflect or transmit light according to the wavelength of light, thereby coupling light of a specific wavelength in the external light into the optical waveguide 32, which is beneficial to improving the conversion efficiency of the photoelectric converter 2, and thus improving the battery life of the electronic device 200.

[0224] Optionally, the aforementioned reflective structure 332 can be a mirror, a photonic crystal, etc., and this embodiment is not limited to this. As an example, the reflective structure 332 is a mirror, which can effectively reflect external light transmitted by the optical waveguide 32 to the photoelectric converter 2; furthermore, it can reduce light loss during the coupling process and selectively enhance the coupling of light of the desired wavelength, which is beneficial to improving the light transmission efficiency, thereby improving the power converted by the photoelectric converter 2, and thus improving the battery life of the electronic device 200. Another example is a photonic crystal, whose periodic structure can reflect light of a specific wavelength, thereby achieving efficient wavelength-selective reflection, enhancing the coupling of light of the desired wavelength, which is beneficial to improving the light transmission efficiency, thereby improving the power converted by the photoelectric converter 2, and thus improving the battery life of the electronic device 200.

[0225] As an optional implementation, the material of the optical waveguide 32 may include glass, polymethyl methacrylate or plastic, etc., and this embodiment does not limit it.

[0226] The use of glass, polymethyl methacrylate, or plastic materials enables the waveguide 32 to have high transparency, thermal stability, and good mechanical properties, which is beneficial for the transmission of display light from the display panel 1 and for improving the overall structural stability of the display assembly 100.

[0227] As an optional implementation, the thickness of the optical waveguide 32 is 0.1mm-3mm. By setting the thickness range of the optical waveguide 32, the transmittance of visible light of the optical waveguide 32 can be within a relatively large range, avoiding the problem that the transmittance of visible light would be too small due to the excessive thickness of the optical waveguide 32, which would affect the transmission of display light, thereby improving the display effect of the display component 100.

[0228] Optionally, the thickness of the aforementioned optical waveguide 32 is 0.1mm-3mm, and can be, for example, 0.1mm, 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm, etc. This embodiment does not limit this.

[0229] Optionally, the thickness of the aforementioned optical waveguide 32 is 0.1mm-3mm, specifically 0.5mm-3mm. Alternatively, the thickness of the optical waveguide 32 can be 0.5mm-2.8mm, 0.5mm-2.6mm, 0.5mm-2.4mm, 0.5mm-2.2mm, 0.5mm-2mm, 0.5mm-1.8mm, 0.5mm-1.6mm, 0.5mm-1.4mm, or 0.5mm-1.2mm. Alternatively, the thickness of the optical waveguide 32 may be 0.5mm-1mm, etc., but this embodiment does not limit it.

[0230] Considering that the coupling unit 31, the optical waveguide 32, and the coupling unit 33 can be integrally formed or separately formed, in some embodiments, at least two of the coupling unit 31, the optical waveguide 32, and the coupling unit 33 are integrally formed. That is, the coupling unit 31 and the optical waveguide 32 can be integrally formed, and the coupling unit 33 can be spaced apart from the coupling unit 31 and the optical waveguide 32; the optical waveguide 32 and the coupling unit 33 can be integrally formed, and the coupling unit 31 can be spaced apart from the optical waveguide 32 and the coupling unit 33; the coupling unit 31 and the coupling unit 33 can be integrally formed, and the optical waveguide 32 can be spaced apart from the coupling unit 31 and the coupling unit 33; or, the coupling unit 31, the optical waveguide 32, and the coupling unit 33 can all be integrally formed. This embodiment does not limit this.

[0231] By integrating the components, the thickness of the optical waveguide module 3 can be reduced, which is beneficial to improving the overall compactness of the display component 100 and thus facilitating its modularity and integration. At the same time, it simplifies the assembly process of the display component 100. During the assembly process, it is not necessary to adjust the relative positions of the coupling unit 31, the optical waveguide 32, and the coupling unit 33, which is beneficial to improving the assembly efficiency of the display component 100.

[0232] It is understandable that the coupling unit 31, the coupling unit 33 and the optical waveguide 32 can be integrated by forming the coupling unit 31 and the coupling unit 33 on the optical waveguide 32 through methods such as etching, nanoimprinting or femtosecond direct writing; or they can be integrated through geometric optical waveguide technology.

[0233] Optionally, when the coupling unit 31 includes the first diffraction grating structure 311, the coupling unit 31 can be etched onto the optical waveguide 32, or the coupling unit 31 can be nanoimprinted onto the optical waveguide 32, or the coupling unit 31 can be femtosecond direct-write onto the optical waveguide 32.

[0234] Optionally, when the coupling unit 33 includes the second diffraction grating structure 331, the coupling unit 33 can be etched onto the optical waveguide 32, or the coupling unit 33 can be nanoimprinted onto the optical waveguide 32, or the coupling unit 33 can be femtosecond direct-write onto the optical waveguide 32.

[0235] Optionally, when the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, the coupling unit 31 is formed in the optical waveguide 32 by means of a geometric optical waveguide process.

[0236] Optionally, when the coupling unit 33 includes a reflective structure 332, the coupling unit 33 is formed within the optical waveguide 32 by a geometric optical waveguide process.

[0237] It should be noted that the above-mentioned geometric optical waveguide process refers to the following steps: First, waveguide prisms of various specifications are obtained by cutting substrates such as glass, polymethyl methacrylate, or plastic. Then, the prisms are rough-ground, fine-ground, and polished. Next, thin films of different film systems are deposited on the prisms to obtain different reflection / transmission ratios. Finally, the prisms are glued together and fixed in the smooth optical waveguide component 32. The waveguide component is then tested using instruments such as a goniometer and an interferometer.

[0238] Optionally, when the coupling unit 31 includes a first diffraction grating structure 311 and the coupling unit 33 includes a reflection structure 332, the coupling unit 33 can be formed in the optical waveguide 32 by a geometric optical waveguide process, and the coupling unit 31 can be etched onto the optical waveguide 32; or, the coupling unit 33 can be formed in the optical waveguide 32 by a geometric optical waveguide process, and the coupling unit 31 can be nanoimprinted onto the optical waveguide 32; or, the coupling unit 33 can be formed in the optical waveguide 32 by a geometric optical waveguide process, and the coupling unit 31 can be femtosecond direct writing onto the optical waveguide 32.

[0239] Optionally, when the coupling unit 31 includes a semi-transparent and semi-reflective structure 312 and the coupling unit 33 includes a second diffraction grating structure 331, the coupling unit 31 can be formed in the optical waveguide 32 by a geometric optical waveguide process, and the coupling unit 33 can be etched onto the optical waveguide 32; or, the coupling unit 31 can be formed in the optical waveguide 32 by a geometric optical waveguide process, and the coupling unit 33 can be nanoimprinted onto the optical waveguide 32; or, the coupling unit 31 can be formed in the optical waveguide 32 by a geometric optical waveguide process, and the coupling unit 33 can be femtosecond direct writing onto the optical waveguide 32.

[0240] By forming the coupling unit 31 and coupling unit 33 on the optical waveguide 32 through etching, nanoimprinting, femtosecond direct writing, or geometric waveguide technology, the overall compactness of the display component 100 is further improved, which is conducive to the further modularization and integration of the display component 100. On the other hand, high-precision processing of the coupling unit 31 and coupling unit 33 can be achieved, and the geometry and surface characteristics of the coupling unit 31 and coupling unit 33 can be precisely controlled, thereby ensuring that the size and shape of the coupling unit meet the design requirements. This is beneficial to improving the coupling efficiency and transmission efficiency of the optical waveguide module 3 to external light, which in turn is beneficial to improving the power conversion of the photoelectric conversion element 2 and improving the battery life of the electronic device 200.

[0241] Please combine Figure 15 , Figure 15 This is a schematic diagram of the structure of the display component (including the cover plate) provided in an embodiment of this application. As an optional implementation, such as... Figure 15 As shown in (a), the display assembly 100 also includes a cover plate 4, which is disposed between the display panel 1 and the optical waveguide module 3. The cover plate 4 can protect the display panel 1, which helps to reduce the risk of scratches and damage to the display panel 1 and extend the service life of the display panel 1. Furthermore, by selecting appropriate materials and coatings, the light transmittance and reflection characteristics of the cover plate 4 can be improved, thereby enhancing the clarity and brightness of the image of the display assembly 100 and improving the viewing experience.

[0242] Optionally, such as Figure 15 As shown in (b), the cover plate 4 is disposed on the side of the optical waveguide module 3 facing away from the display panel 1. Thus, the cover plate 4 can also provide an additional buffer layer for the optical waveguide module 3, which can absorb external impacts and help reduce the risk of damage to the display component 100 when dropped or bumped.

[0243] To improve the collection and conduction of external light, multiple optical waveguide modules 3 can be provided, arranged sequentially along the thickness direction of the display panel 1. By stacking multiple optical waveguide modules 3, the design can be optimized for external light of different wavelengths, thereby improving the overall optical coupling efficiency of the display component 100, reducing the loss of external light during conduction, thus improving the power conversion of the photoelectric conversion element 2, and consequently improving the battery life of the electronic device 200.

[0244] Please see Figure 16 , Figure 16 This is a schematic diagram of the structure of the electronic device provided in the embodiments of this application. Secondly, the embodiments of this application also disclose an electronic device 200, including a power module 202 and a display component 100 as described in the first aspect above, wherein the power module 202 is electrically connected to the display component 100. The electronic device 200 having the display component 100 described in the first aspect can also prevent the optical waveguide module 3 from affecting the display of the display panel 1, thereby avoiding affecting the functionality of the electronic device 200; and can improve the battery life of the electronic device 200, thus facilitating the miniaturization of the electronic device 200 while maintaining its battery life.

[0245] Optionally, the aforementioned electronic device 200 includes a terminal device or an electronic billboard. A terminal device or electronic billboard having the display component 100 described in the first aspect can also prevent the optical waveguide module 3 from affecting the display panel 1, and can improve the battery life of the terminal device or electronic billboard. The terminal device may include, but is not limited to, smartwatches, smart bracelets, smart glasses, mobile phones, tablets, etc.

[0246] It is understandable that this electronic billboard can be an outdoor electronic billboard, thus achieving outdoor display while also collecting solar energy through the display component 100, and then performing photoelectric conversion to power the electronic billboard. In this case, the electronic billboard does not need a built-in battery and is directly powered by the display component 100. Alternatively, the electronic billboard can also be equipped with a built-in battery, thereby being powered and charged through the display component 100.

[0247] It is understandable that the terminal product can be a mobile phone, so that when the mobile phone is used outdoors, it can display information through the display component 100, and can also collect solar energy through the display component 100, and then perform photoelectric conversion to power the mobile phone. In this case, when the power consumption of the mobile phone is lower than the power generation of the display component 100, the display component 100 can power and charge the mobile phone.

[0248] It is understood that the aforementioned power module 202 may be an amplifier, oscillator, mixer, filter, heat sink, lamp assembly, etc., and this embodiment does not limit it.

[0249] Of course, the electronic device 200 may also include a power supply module 201, which is electrically connected to the power consumption module 202 and the display component 100. The power supply module 201 can supply power to the power consumption module 202 and the display panel 1.

[0250] It is understood that the power supply module 201 mentioned above can be a lead-acid battery, a nickel-metal hydride battery, a nickel-cadmium battery, a lithium battery, a solid-state battery, etc., and this embodiment does not limit it.

[0251] As an optional implementation method, such as Figure 16 As shown, the electronic device 200 also includes a power management system 203, which is electrically connected to the power supply module 201, the power consumption module 202, and the display component 100. The power management system 203 is used to detect the power generation of the photoelectric converter 2 and the power consumption of the power consumption module 202 and the display panel 1. When the power generation is greater than or equal to the power consumption, the power management system 203 controls the photoelectric converter 2 to supply power to the power consumption module 202 and the display panel 1. The portion of the power generation of the photoelectric converter 2 that exceeds the power consumption module 202 and the display panel 1 is used to supply power to the power supply module 201. When the power generation is less than the power consumption, the power management system 203 controls the photoelectric converter 2 to supply power to the power consumption module 202 and the display panel 1, and the power management system 203 controls the power supply module 201 to supply power to the power consumption module 202 and the display panel 1.

[0252] The power management system 203 can rationally allocate the power generation of the photoelectric converter 2 in the display component 100. By prioritizing the power generation for the power-consuming module 202 and the display panel 1, the dependence of the power-consuming module 202 and the display panel 1 on the power supply module 201 can be reduced, extending the service life of the power supply module 201 and reducing losses caused by frequent charging and discharging. Furthermore, directly supplying the power generation to the power-consuming module 202 and the display panel 1 shortens the transmission path of the power generation from the photoelectric converter 2, reducing power loss during transmission and further improving the battery life of the electronic device 200. In addition, effective power management can prevent instability in the power system of the electronic device 200 due to power fluctuations, thereby improving the overall reliability and stability of the electronic device 200.

[0253] It is understood that the power management system 203 described above may include control circuits, microcontrollers or single-chip microcomputers and sensors, etc., and this embodiment does not limit it.

[0254] Thirdly, this application also discloses a power management method, which can be implemented by the electronic device 200 described in the second aspect above.

[0255] Please combine Figure 17 , Figure 17 This is a first schematic diagram of a power management method provided in an embodiment of this application. When the electronic device includes a power supply module, the power management method includes the following steps:

[0256] 301. Detect the power generation of the photoelectric conversion component and the power consumption of the power module and display panel.

[0257] During the use of the electronic device 200, the power management system 203 on the electronic device 200 detects the power generation of the photoelectric conversion element 2 and the power consumption of the power consumption module 202 and the display panel 1, and determines the relationship between the power consumption and the power generation.

[0258] 302. If the power generation of the photoelectric converter is greater than or equal to the power consumption of the power module and the display panel, control the photoelectric converter to supply power to the power module and the display panel.

[0259] When the power management system 203 determines that the power generation of the photoelectric converter 2 is equal to the power consumption of the power-consuming module 202 and the display panel 1, the power management system 203 controls the power converted by the photoelectric converter 2 to be directly transmitted to the power-consuming module 202 and the display panel 1 for their use. When the power management system 203 determines that the power generation of the photoelectric converter 2 is greater than the power consumption of the power-consuming module 202 and the display panel 1, the power management system 203 controls a portion of the power converted by the photoelectric converter 2 to be directly transmitted to the power-consuming module 202 and the display panel 1 for their use, while the remaining power is directly transmitted to the power supply module 201 to charge the power supply module 201.

[0260] Among them, a portion of the electrical energy converted by the photoelectric conversion element 2 is equal to the electrical energy consumed.

[0261] Please combine Figure 18 , Figure 18 This is a second schematic diagram of the power management method provided in this application embodiment. In another embodiment, when the electronic device includes a power supply module, the power management method includes the following steps:

[0262] 301. Detect the power generation of the photoelectric conversion component and the power consumption of the power module and display panel.

[0263] During the use of the electronic device 200, the power management system 203 on the electronic device 200 detects the power generation of the photoelectric conversion element 2 and the power consumption of the power consumption module 202 and the display panel 1, and determines the relationship between the power consumption and the power generation.

[0264] 303. If the power generation of the photoelectric conversion device is less than the power consumption of the power module and the display panel, control the photoelectric conversion device to supply power to the power module and the display panel, and control the power supply module to supply power to the power module and the display panel.

[0265] When the power management system 203 determines that the power generation of the photoelectric converter 2 is less than the power consumption of the power consumption module 202 and the display panel 1, the power management system 203 controls the power converted by the photoelectric converter 2 to be directly transmitted to the power consumption module 202 and the display panel 1 for their use; and the power management system 203 controls the power supply module 201 to supply power to the power consumption module 202 and the display panel 1 to ensure the normal operation of the power consumption module 202 and the display panel 1.

[0266] For example, during the use of electronic device 200, power management system 203 detects the power generation of photoelectric conversion element 2 and the power consumption of power module 202 and display panel 1. When the power generation, for example, is 0.006kWh, is greater than the power consumption, for example, is 0.005kWh, power management system 203 controls 0.005kWh of the power generation (0.006kWh) to be directly transmitted to power module 202 and display panel 1 for their use. The remaining 0.001kWh of power is directly transmitted to power supply module 201 to charge power supply module 201.

[0267] If the power generation, say 0.003 kWh, is less than the power consumption, say 0.005 kWh, then the power management system 203 controls all of the 0.003 kWh of power generation to be directly transmitted to the power consumption module 202 and the display panel 1 for their use. In addition, the power management system 203 controls the power supply module 201 to supply 0.002 kWh of power to the power consumption module 202 and the display panel 1 to ensure the normal operation of the power consumption module 202 and the display panel 1.

[0268] Please see Figures 19 to 21 , Figure 19 This is a schematic diagram of the structure of the photoelectric conversion module provided in the embodiments of this application; Figure 20 yes Figure 19 A schematic diagram of the direction of external light transmission in the photoelectric conversion module; Figure 21This is a schematic diagram of the structure of the photoelectric conversion module (photoelectric conversion element disposed on the first surface) provided in the embodiments of this application. In a fourth aspect, embodiments of this application also disclose a photoelectric conversion module 400, including a photoelectric conversion element 2 and an optical waveguide module 3. The photoelectric conversion element 2 is configured to convert light energy into electrical energy. The optical waveguide module 3 includes an input unit 31, an optical waveguide element 32, and an output unit 33. The input unit 31 is configured to conduct external light to the optical waveguide element 32. The optical waveguide element 32 is configured to conduct the external light transmitted by the input unit 31 to the output unit 33. The output unit 33 is configured to conduct the external light transmitted by the optical waveguide element 32 onto the photoelectric conversion element 2.

[0269] The photoelectric conversion module 400 provided in this application embodiment enables the utilization of solar energy and can be applied to the display component 100 and the electronic device 200. This photoelectric conversion module 400 collects external light through the coupling unit 31, preventing external light from directly passing through the optical waveguide 32 and failing to be conducted to the photoelectric conversion module 2 for utilization. Simultaneously, the process of external light being conducted to the photoelectric conversion module 2 is realized through the optical waveguide 32 and the coupling unit 33. Furthermore, the optical waveguide 32 reduces energy loss during the conduction of external light, facilitating efficient conduction of external light, thereby increasing the amount of electricity converted by the photoelectric conversion module 2, and consequently improving the power supply efficiency of the photoelectric conversion module 400.

[0270] Optionally, such as Figure 20 and Figure 21 As shown, the coupling unit 31, optical waveguide 32, and coupling unit 33 transmit external light to the photoelectric converter 2. This can be achieved, for example, through reflection; that is, the coupling unit 31, optical waveguide 32, and coupling unit 33 transmit external light to the photoelectric converter 2 through gradual reflection. Alternatively, it can be achieved, for example, through refraction; that is, the coupling unit 31, optical waveguide 32, and coupling unit 33 transmit external light to the photoelectric converter 2 through gradual refraction. Furthermore, it can also transmit external light through a combination of reflection and refraction, which will not be elaborated upon in this embodiment.

[0271] Optionally, the aforementioned photoelectric conversion element 2 may include solar cells, organic photovoltaic cells, etc., and this embodiment does not limit this.

[0272] For example, the photoelectric conversion element 2 includes a solar cell. Because solar cells have a long lifespan and low maintenance requirements, the photoelectric conversion element 2 also has a long lifespan, thereby improving the lifespan of the display assembly 100 and reducing maintenance costs. As another example, the photoelectric conversion element 2 includes an organic photovoltaic cell. Because organic photovoltaic cells are flexible, the photoelectric conversion element 2 is malleable, allowing its shape to be freely changed to meet the needs of the display assembly 100.

[0273] Optionally, when the photoelectric conversion element 2 includes a solar cell, the material of the photoelectric conversion element 2 may include monocrystalline silicon, perovskite, or gallium arsenide, etc., and this embodiment does not limit this.

[0274] For example, the photoelectric converter 2 can be made of monocrystalline silicon. Monocrystalline silicon typically has high conversion efficiency, good stability, and strong durability, which helps improve the utilization rate of external light transmitted by the optical waveguide module 3 and extends the lifespan of the photoelectric converter 2, thus improving the lifespan of the display component 100. Alternatively, the photoelectric converter 2 can be made of perovskite. Perovskite has high efficiency potential, low cost, and lightweight properties, which further improves the utilization rate of external light transmitted by the optical waveguide module 3, reduces the production cost of the display component 100, and allows it to be made into a flexible material, facilitating various innovative applications. Another example is the photoelectric converter 2 made of gallium arsenide. Gallium arsenide has extremely high efficiency and light weight, allowing the photoelectric converter 2 to maintain high efficiency even under low light conditions and reducing the overall weight of the display component 100.

[0275] Optionally, when the photoelectric conversion element 2 includes an organic photovoltaic cell, the material of the photoelectric conversion element 2 is an organic photovoltaic material, which can be an organic polymer, such as poly(3-hexene), poly(3,4-ethylenedioxythiophene), etc.; or it can be an organic small molecule, such as fullerene derivatives, organic dyes, etc. This embodiment does not limit this.

[0276] For example, the photoelectric conversion element 2 can be made of an organic polymer. Due to the flexibility, low-temperature processing, and tunable spectral absorption of organic polymers, the photoelectric conversion element 2 can be manufactured into a thin and lightweight photovoltaic module. It can also be processed at lower temperatures, which is beneficial for energy conservation and environmental protection, and reduces the production cost of the display module 100. Furthermore, by designing the chemical structure of the organic polymer, the absorption of specific wavelengths of light by the photoelectric conversion element 2 can be optimized, thus improving the photoelectric conversion efficiency. As another example, the photoelectric conversion element 2 can be made of small organic molecules. Due to the good electronic conductivity, ease of combination, and solubility of small organic molecules, the photoelectric conversion element 2 can achieve highly efficient energy conversion, thereby improving its photoelectric conversion efficiency. It can also combine small organic molecules with other materials (such as nanoparticles or polymers) to form composite materials, further improving the photoelectric conversion efficiency of the photoelectric conversion element 2. Simultaneously, by utilizing the solubility of small organic molecules, the photoelectric conversion element 2 can be prepared by dissolving the small organic molecules and then using methods such as spraying or printing, which helps reduce the manufacturing cost of the display module 100.

[0277] Optionally, the material of the photoelectric conversion element 2 can also be a hybrid material such as perovskite-organic hybrid material or gallium arsenide-organic hybrid material, and this embodiment does not limit this.

[0278] Optionally, such as Figure 20 and Figure 21 As shown, along the direction of external light transmission, the coupling unit 31 is positioned upstream of the optical waveguide 32, the optical waveguide 32 is positioned upstream of the coupling unit 33, and the coupling unit 33 is positioned upstream of the photoelectric conversion module 2. By sequentially arranging the coupling unit 31, optical waveguide 32, coupling unit 33, and photoelectric conversion module 2 along the direction of external light transmission, external light can be transmitted between these components. This facilitates smooth transmission of external light between different components, thereby optimizing the power supply performance of the photoelectric conversion module 400. Furthermore, this method effectively avoids light loss and scattering during transmission, thereby improving the transmission efficiency and signal quality of external light, and ultimately enhancing the power supply efficiency of the photoelectric conversion module 400.

[0279] The specific configurations of the photoelectric conversion element 2, the coupling unit 31, the optical waveguide 32, and the coupling unit 33 will be described in detail below with reference to the accompanying drawings.

[0284] Please combine Figure 23 , Figure 23 This is a schematic diagram of the structure of a photoelectric conversion module (with photoelectric conversion components disposed on the first and second surfaces of an optical waveguide) provided in an embodiment of this application. Optionally, the optical waveguide 32 has a first surface 401 and a second surface 402 facing away from the first surface 401, and the photoelectric conversion component 2 is disposed on the first surface 401 and the second surface 402.

[0285] Please combine Figure 24 and Figure 25 , Figure 24 This is a schematic diagram of the structure of the photoelectric conversion module (the photoelectric conversion element is disposed on the side surface, the first surface and the second surface of the optical waveguide) provided in the embodiment of this application; Figure 25 This is a schematic diagram of the structure of the photoelectric conversion module (coupling unit includes two) provided in the embodiments of this application. Optionally, the optical waveguide 32 has an optical waveguide 32 and a second surface 402 facing away from the first surface 401, and the photoelectric conversion element 2 is disposed on the side surface of the first surface 401, the second surface 402 and the optical waveguide 32.

[0286] These methods enable the photoelectric conversion module 400 to adapt to the application requirements of different display components 100 and electronic devices 200, thereby improving the applicability of the photoelectric conversion module 400. Furthermore, by simultaneously placing the photoelectric conversion element 2 on different surfaces of the optical waveguide 32, the area of ​​the photoelectric conversion element 2 receiving external light transmitted by the optical waveguide 32 can be increased, thereby further increasing the amount of electricity converted by the photoelectric conversion element 2, and consequently further improving the battery life of the electronic device 200.

[0287] It is understood that in the above embodiments, the photoelectric conversion element 2 includes one or more.

[0288] Optionally, such as Figure 22 As shown in (a) and (c), the photoelectric conversion element 2 includes two photoelectric conversion elements 2, one of which is disposed on the side surface of the optical waveguide 32, and the other photoelectric conversion element 2 is disposed on the second surface 402.

[0289] Optionally, such as Figure 22 As shown in (b), the photoelectric conversion element 2 includes two photoelectric conversion elements 2. One photoelectric conversion element 2 is disposed on the side surface of the optical waveguide 32, and the other photoelectric conversion element 2 is disposed on the first surface 401.

[0290] Optionally, such as Figure 23 As shown, the photoelectric conversion element 2 includes two photoelectric conversion elements 2, one of which is disposed on the first surface 401 and the other of which is disposed on the second surface 402.

[0291] Optionally, such as Figure 24 and 25 As shown, the photoelectric conversion element 2 includes three components, which are respectively disposed on the side surface, the first surface 401 and the second surface 402 of the optical waveguide 32.

[0292] It is understood that when there are multiple photoelectric conversion elements 2, the multiple photoelectric conversion elements 2 can be arranged at intervals or connected to each other. This embodiment does not limit this.

[0293] Please see Figures 26 to 28 , Figure 26 This is a schematic diagram of the structure of the photoelectric conversion module (the photoelectric conversion component includes a first part and a second part) provided in the embodiments of this application; Figure 27 This is a schematic diagram of the structure of the photoelectric conversion module (the photoelectric conversion component includes a first part, a second part, and a third part) provided in the embodiment of this application; Figure 28 This is a schematic diagram of the structure of the photoelectric conversion module (the photoelectric conversion element includes a first part, a second part, and a third part, and the coupling unit includes two parts) provided in the embodiments of this application. It can be understood that when the side surface of the optical waveguide 32 is provided with the photoelectric conversion element 2, and when at least one of the first surface 401 and the second surface 402 is provided with the photoelectric conversion element 2, the photoelectric conversion element 2 may also include one part, which will be described in detail below.

[0294] Optionally, such as Figure 26As shown in (a) and (c), the photoelectric conversion element 2 includes a first part 21 and a second part 22 connected to the first part 21. The first part 21 is located on the second surface 402, and the second part 22 is located on the side surface of the optical waveguide 32. That is, the photoelectric conversion element 2 is L-shaped and disposed on the second surface 402 and the side surface of the optical waveguide 32.

[0295] Optionally, such as Figure 26 As shown in (b), the photoelectric conversion element 2 includes a first part 21 and a second part 22 connected to the first part 21. The first part 21 is located on the first surface 401, and the second part 22 is located on the side surface of the optical waveguide 32. That is, the photoelectric conversion element 2 is L-shaped and disposed on the first surface 401 and the side surface of the optical waveguide 32.

[0296] Optionally, such as Figure 27 and Figure 28 As shown, the photoelectric conversion element 2 includes a first part 21, a second part 22, and a third part 23 connected in sequence. The first part 21 is located on the first surface 401, the second part 22 is located on the side surface of the optical waveguide 32, and the third part 23 is located on the second surface 402. That is, the photoelectric conversion element 2 is arranged in a U-shape on the first surface 401, the side surface of the optical waveguide 32, and the second surface 402.

[0297] The second part 22 on the photoelectric converter 2 can receive light transmitted to the side surface from the optical waveguide 32, which helps to increase the area of ​​the photoelectric converter 2 that receives external light transmitted by the optical waveguide module 3, thereby further increasing the amount of electricity converted by the photoelectric converter 2 and thus further improving the battery life of the electronic device 200. In addition, the integrated arrangement of the first part 21, the second part 22 and the third part 23 facilitates the assembly of the photoelectric converter module 400 and simplifies the assembly difficulty of the photoelectric converter module 400.

[0298] Optionally, such as Figure 27 and Figure 28 As shown, when the photoelectric conversion element 2 is disposed on the first surface 401 and the second surface 402, the coupling unit 33 may include one or more. For example, as Figure 27 As shown, the coupling unit 33 includes one unit, which is disposed on the first surface 401 or the second surface 402 corresponding to the photoelectric conversion element 2, and the coupling unit 33 is located between the photoelectric conversion element 2 and the optical waveguide element 32. For example, as... Figure 28 As shown, the coupling unit 33 includes two units, which are respectively disposed on the first surface 401 and the second surface 402 corresponding to the photoelectric conversion element 2, and both coupling units 33 are located between the photoelectric conversion element 2 and the optical waveguide element 32.

[0299] It should be noted that, for the convenience of the detailed description of the coupling unit 31, the optical waveguide 32, and the coupling unit 33 below, the accompanying drawings will be shown with the photoelectric conversion element 2 disposed on the second surface 402 of the optical waveguide 32 as an example.

[0300] Please combine Figures 29 to 31 , Figure 29 This is a schematic diagram of the structure of the photoelectric conversion module (with a first diffraction grating disposed on the first surface) provided in the embodiment of this application; Figure 30 This is a schematic diagram of the structure of the photoelectric conversion module (with a first diffraction grating disposed on the second surface) provided in the embodiment of this application; Figure 31 This is a schematic diagram of the photoelectric conversion module (coupling unit includes a semi-transparent and semi-reflective structure) provided in the embodiments of this application. To improve the efficiency of light transmission from the coupling unit 33 to the photoelectric conversion element 2, the positional relationship between the coupling unit 33 and the photoelectric conversion element 2 is considered. Specifically, as shown... Figures 29 to 31 As shown, the coupling unit 33 and the photoelectric conversion element 2 are positioned near the edge of the first surface 401. This effectively reduces light reflection at the interface between the optical waveguide 32 and the air, thereby improving light transmission efficiency. Furthermore, by placing the photoelectric conversion element 2 near the edge of the optical waveguide 32, it can be better matched to the optical waveguide 32, thus improving the coupling efficiency between the optical waveguide module 3 and the photoelectric conversion element 2.

[0301] Optionally, the projection of the coupling unit 33 on the first surface 401 is located within the projection range of the photoelectric converter 2 on the first surface 401. This prevents external light transmitted by the coupling unit 33 from falling outside the photoelectric converter 2, which improves light transmission efficiency, allows the photoelectric converter 2 to receive more light energy, and thus increases the amount of electricity converted by the photoelectric converter 2, further improving the power supply efficiency of the photoelectric conversion module 400.

[0302] It is understood that the coupling unit 31 may include, for example, a first diffraction grating structure 311 or a semi-transparent and semi-reflective structure 312, etc., and this embodiment does not limit it.

[0303] Optionally, such as Figure 29 As shown, the coupling unit 31 includes a first diffraction grating structure 311, which is disposed on the first surface 401.

[0304] Optionally, such as Figure 30 As shown, the coupling unit 31 includes a first diffraction grating structure 311, which is disposed on the second surface 402.

[0305] Optionally, such as Figure 31As shown, the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, which is disposed within the optical waveguide 32.

[0306] The aforementioned configuration of the coupling unit 31 as either a first diffraction grating structure 311 or a semi-transparent, semi-reflective structure 312 allows for the reflection of external light, enabling it to enter the optical waveguide 32 at a suitable incident angle, thereby achieving the purpose of collecting external light. Simultaneously, by adjusting the transmittance and reflectivity of the first diffraction grating structure 311 or the semi-transparent, semi-reflective structure 312, the transmission characteristics of external light entering the optical waveguide 32 can be more flexibly controlled, thus facilitating better realization of the optical performance of the coupling unit 31. Furthermore, placing the semi-transparent, semi-reflective structure 312 within the optical waveguide 32 allows for efficient integration of the optical waveguide module 3, simplifying the overall layout of the photoelectric conversion module 400.

[0307] Correspondingly, such as Figures 29 to 31 As shown, the coupling unit 33 may include, for example, a second diffraction grating structure 331 or a reflection structure 332.

[0308] Optionally, such as Figure 29 (a) Figure 30 (a) and Figure 31 As shown in (a), the coupling unit 33 includes a second diffraction grating structure 331, which is disposed on the first surface 401 and is disposed corresponding to the photoelectric conversion element 2.

[0309] Optionally, such as Figure 29 (b) Figure 30 (b) and Figure 31 As shown in (b), the coupling unit 33 includes a second diffraction grating structure 331, which is disposed on the second surface 402 and is disposed corresponding to the photoelectric conversion element 2.

[0310] Optionally, such as Figure 29 (c) Figure 30 (c) and Figure 31 As shown in (c), the coupling unit 33 includes a reflection structure 332, which is disposed within the optical waveguide 32 and corresponds to the photoelectric conversion unit 2.

[0311] By configuring the coupling unit 33 as either a second diffraction grating structure 331 or a reflection structure 332, light rays in the optical waveguide 32 can be reflected, thereby guiding the light rays in the optical waveguide 32 to the photoelectric converter 2 to convert light energy into electrical energy. Simultaneously, by placing the second diffraction grating structure 331 on the optical waveguide 32, light rays can be effectively extracted from the optical waveguide 32, reducing light loss within the optical waveguide 32 and enabling more efficient coupling of light rays. Furthermore, through the diffraction effect, the propagation direction of the light rays can be adjusted, allowing them to better enter the photoelectric converter 2 and improving the conversion efficiency of the photoelectric converter 2. In addition, by placing the reflection structure 332 corresponding to the photoelectric converter 2 within the optical waveguide 32, light rays are reflected internally within the optical waveguide 32, effectively reducing interference from the external environment on light transmission, thus improving the system stability and reliability of the optical waveguide module 3.

[0312] In some alternative implementations, when the coupling unit 31 is a first diffraction grating, the coupling unit 33 can be a second diffraction grating structure 331 or a reflection structure 332. For example, an exemplary embodiment... Figure 29 As shown in (a), when the first diffraction grating structure 311 is disposed on the first surface 401, the coupling unit 33 includes a second diffraction grating structure 331. The second diffraction grating structure 331 is disposed on the first surface 401 corresponding to the photoelectric conversion element 2, and the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed adjacent to each other.

[0313] Another example, such as Figure 29 As shown in (b), when the first diffraction grating structure 311 is disposed on the first surface 401, the coupling unit 33 includes a second diffraction grating structure 331, which is disposed on the second surface 402 and is disposed corresponding to the photoelectric conversion element 2.

[0314] Another example, such as Figure 29 As shown in (c), when the first diffraction grating structure 311 is disposed on the first surface 401, the coupling unit 33 includes a reflection structure 332, which is disposed within the optical waveguide 32 and corresponds to the photoelectric conversion unit 2.

[0315] Another example, such as Figure 30 As shown in (a), when the first diffraction grating structure 311 is disposed on the second surface 402, the coupling unit 33 includes a second diffraction grating structure 331, which is disposed on the first surface 401 and is disposed corresponding to the photoelectric conversion element 2.

[0316] Another example, such as Figure 30As shown in (b), when the first diffraction grating structure 311 is disposed on the second surface 402, the coupling unit 33 includes a second diffraction grating structure 331. The second diffraction grating structure 331 is disposed on the second surface 402 corresponding to the photoelectric conversion element 2, and the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed adjacent to each other.

[0317] Another example, such as Figure 30 As shown in (c), when the first diffraction grating structure 311 is disposed on the second surface 402, the coupling unit 33 includes a reflection structure 332, which is disposed within the optical waveguide 32 and corresponds to the photoelectric conversion unit 2.

[0318] In other alternative embodiments, when the coupling unit 31 is a semi-transparent, semi-reflective structure 312, the coupling unit 33 can also be a second diffraction grating structure 331 or a reflective structure 332. For example, an exemplary embodiment... Figure 31 As shown in (a), when the coupling unit 31 is a semi-transparent and semi-reflective structure 312, the coupling unit 33 includes a second diffraction grating structure 331, and the second diffraction grating structure 331 is disposed on the first surface 401 corresponding to the photoelectric conversion element 2.

[0319] Another example, such as Figure 31 As shown in (b), when the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, the coupling unit 33 includes a second diffraction grating structure 331, and the second diffraction grating structure 331 is disposed on the second surface 402 corresponding to the photoelectric conversion element 2.

[0320] Another example, such as Figure 31 As shown in (c), when the coupling unit 31 includes a semi-transparent and semi-reflective structure 312, the coupling unit 33 includes a reflective structure 332. The reflective structure 332 is disposed within the corresponding photoelectric conversion element 2 disposed within the optical waveguide element 32, and the reflective structure 332 is located on the periphery of the semi-transparent and semi-reflective structure 312.

[0321] Through various structural combinations of the coupling-in unit 31 and the coupling-out unit 33, the optical waveguide module 3 possesses high flexibility, optimized performance, and compatibility. This allows the optical waveguide module 3 to adapt to the application requirements of different types of display components 100 or electronic devices 200 by adjusting different structural combinations of the coupling-in unit 31 and the coupling-out unit 33. Simultaneously, by selecting the most suitable combination, the light transmission efficiency and photoelectric conversion efficiency can be effectively improved. Furthermore, these various structural combinations enable the display component 100 to be well-matched with photoelectric conversion devices 2 of different specifications and types, which is beneficial to improving the adaptability and compatibility of the photoelectric conversion module 400.

[0322] In some optional embodiments, when both the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on the first surface 401 or the second surface 402, the second diffraction grating structure 331 is disposed on the periphery of the first diffraction grating structure 311. That is, when both the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on the first surface 401, the second diffraction grating structure 331 is disposed on the periphery of the first diffraction grating structure 311. Alternatively, when both the first diffraction grating structure 311 and the second diffraction grating structure 331 are disposed on the second surface 402, the second diffraction grating structure 331 is disposed on the periphery of the first diffraction grating structure 311.

[0323] In some alternative embodiments, when one of the first diffraction grating structure 311 and the second diffraction grating structure 331 is disposed on the first surface 401 and the other is disposed on the second surface 402, the first diffraction grating structure 311 covers the surface on which it is disposed. That is, when the first diffraction grating structure 311 is disposed on the first surface 401 and the second diffraction grating structure 331 is disposed on the second surface 402, the first diffraction grating structure 311 covers the first surface 401. Alternatively, when the first diffraction grating structure 311 is disposed on the second surface 402 and the second diffraction grating structure 331 is disposed on the first surface 401, the first diffraction grating structure 311 covers the second surface 402.

[0324] In some alternative embodiments, when the coupling unit 31 includes a first diffraction grating structure 311 and the coupling unit 33 includes a reflection structure 332, the first diffraction grating structure 311 is disposed over either the first surface 401 or the second surface 402. That is, when the coupling unit 33 includes a reflection structure 332, the first diffraction grating structure 311 can be disposed over either the first surface 401 or the second surface 402. For example, when the coupling unit 33 includes a reflection structure 332 and the first diffraction grating structure 311 is disposed over the first surface 401, the first diffraction grating structure 311 covers the first surface 401. Alternatively, when the coupling unit 33 includes a reflection structure 332 and the first diffraction grating structure 311 is disposed over the second surface 402, the first diffraction grating structure 311 covers the second surface 402.

[0325] Through the above-mentioned various implementation methods, the first diffraction grating structure 311 can have a larger area, thereby effectively increasing the area of ​​the coupling unit 31 that collects external light, which in turn helps to improve the amount of electricity converted by the photoelectric conversion element 2 and further improves the power supply efficiency of the photoelectric conversion module 400.

[0326] Optionally, when the coupling unit 31 includes a first diffraction grating structure 311, the first diffraction grating structure 311 includes, but is not limited to, a surface relief grating or a volume holographic grating.

[0327] Optionally, when the coupling unit 33 includes a second diffraction grating structure 331, the second diffraction grating structure 331 includes, but is not limited to, a surface relief grating or a volume holographic grating.

[0328] Optionally, when the coupling unit 31 includes a first diffraction grating structure 311, the first diffraction grating structure 311 includes, but is not limited to, a surface relief grating or a volume holographic grating, and when the coupling unit 33 includes a second diffraction grating structure 331, the second diffraction grating structure 331 includes, but is not limited to, a surface relief grating or a volume holographic grating. That is, the first diffraction grating structure 311 may include a surface relief grating, and the second diffraction grating structure 331 may include a surface relief grating. Alternatively, the first diffraction grating structure 311 may include a surface relief grating, and the second diffraction grating structure 331 may include a volume holographic grating. Alternatively, the first diffraction grating structure 311 may include a volume holographic grating, and the second diffraction grating structure 331 may include a surface relief grating. Alternatively, the first diffraction grating structure 311 may include a volume holographic grating, and the second diffraction grating structure 331 may include a volume holographic grating.

[0329] By using the first diffraction grating structure 311 and the second diffraction grating structure 331 as surface relief gratings, the manufacturing process of the coupling unit 31 can be simplified, making it relatively easy to manufacture and integrate onto the optical waveguide 32. Furthermore, the coupling angle of the light can be optimized by adjusting the structural parameters of the grating, thereby achieving efficient optical coupling, reducing light energy loss, and improving the electrical charge converted by the photoelectric converter 2, thus improving the power supply efficiency of the photoelectric conversion module 400. Alternatively, by using the first diffraction grating structure 311 and the second diffraction grating structure 331 as volume holographic gratings, multiple wavelengths of external light can be coupled simultaneously, thereby improving the transmission efficiency of external light. Moreover, due to the low-loss characteristics of volume holographic gratings, the scattering and absorption losses of the first diffraction grating structure 311 and the second diffraction grating structure 331 during the transmission of external light can be reduced, which is beneficial to improving the electrical charge converted by the photoelectric converter 2, and thus further improving the power supply efficiency of the photoelectric conversion module 400.

[0330] Optionally, the aforementioned semi-transparent and semi-reflective structure 312 can be a semi-transparent and semi-reflective mirror, a dichroic mirror, etc., and this embodiment is not limited to this. As an example, the semi-transparent and semi-reflective structure 312 is a semi-transparent and semi-reflective mirror, which can couple external light into the optical waveguide 32; and by adjusting the transmittance and reflectance of the semi-transparent and semi-reflective mirror, the intensity of the transmitted light can be precisely controlled, which is beneficial to improving the quality of the transmitted light, thereby improving the conversion efficiency of the photoelectric converter 2, and further improving the power supply efficiency of the photoelectric conversion module 400. Another example is that the semi-transparent and semi-reflective structure 312 is a dichroic mirror, which can selectively reflect or transmit light according to the wavelength of light, thereby coupling light of a specific wavelength in the external light into the optical waveguide 32, thereby improving the conversion efficiency of the photoelectric converter 2, and further improving the power supply efficiency of the photoelectric conversion module 400.

[0331] Optionally, the aforementioned reflective structure 332 can be a mirror, a photonic crystal, etc., and this embodiment is not limited to this. As an example, the reflective structure 332 is a mirror, which can effectively reflect external light transmitted by the optical waveguide 32 to the photoelectric converter 2; furthermore, it can reduce light loss during the coupling process and selectively enhance the coupling of light of the desired wavelength, which is beneficial to improving the light transmission efficiency, thereby improving the electrical charge converted by the photoelectric converter 2, and thus improving the power supply efficiency of the photoelectric conversion module 400. Another example is a photonic crystal, whose periodic structure can reflect light of a specific wavelength, thereby achieving efficient wavelength-selective reflection, enhancing the coupling of light of the desired wavelength, which is beneficial to improving the light transmission efficiency, thereby improving the electrical charge converted by the photoelectric converter 2, and thus improving the power supply efficiency of the photoelectric conversion module 400.

[0332] Considering that the coupling unit 31, the optical waveguide 32, and the coupling unit 33 can be integrally formed or separately formed, in some embodiments, at least two of the coupling unit 31, the optical waveguide 32, and the coupling unit 33 are integrally formed. That is, the coupling unit 31 and the optical waveguide 32 can be integrally formed, and the coupling unit 33 can be spaced apart from the coupling unit 31 and the optical waveguide 32; the optical waveguide 32 and the coupling unit 33 can be integrally formed, and the coupling unit 31 can be spaced apart from the optical waveguide 32 and the coupling unit 33; the coupling unit 31 and the coupling unit 33 can be integrally formed, and the optical waveguide 32 can be spaced apart from the coupling unit 31 and the coupling unit 33; or, the coupling unit 31, the optical waveguide 32, and the coupling unit 33 can all be integrally formed. This embodiment does not limit this.

[0333] By integrating the components, the thickness of the optical waveguide module 3 can be reduced, which helps to improve the overall compactness of the photoelectric conversion module 400, thus facilitating its modularity and integration. At the same time, it simplifies the assembly process of the photoelectric conversion module 400. During the assembly process, it is not necessary to adjust the relative positions of the coupling unit 31, the optical waveguide 32, and the coupling unit 33, which helps to improve the assembly efficiency of the photoelectric conversion module 400.

[0334] It is understandable that the coupling unit 31, the coupling unit 33 and the optical waveguide 32 can be integrated by forming the coupling unit 31 and the coupling unit 33 on the optical waveguide 32 through methods such as etching, nanoimprinting or femtosecond direct writing; or they can be integrated through geometric optical waveguide technology.
