Figure 2 This is a top view of a first film layer provided by an embodiment of the present invention, referring to Figure 1 and Figure 2The phototherapy device includes: a first substrate 100, a second substrate 300 and a light-emitting structure layer 200 located between the first substrate 100 and the second substrate 300; the first substrate 100 includes a first film layer 110 and a second film layer 120, and the second film layer 120 is arranged on a side of the first film layer 110 away from the light-emitting structure layer 200.

[0046] A first groove 10 is provided on the surface of the first film layer 110 adjacent to the second film layer 120, and the first groove 10 includes at least a first end 11 and a second end 12, and the first end 11 and the second end 12 both extend to the side of the first film layer 110 and pass through the side of the first film layer 110, and / or, a second groove 20 is provided on the surface of the second film layer 120 adjacent to the first film layer 110, and the second groove 20 includes at least a third end 21 and a fourth end 22, and the third end 21 and the fourth end 22 both extend to the side of the second film layer 120 and pass through the side of the second film layer 120; wherein, the side of the first film layer 110 is a surface of the first film layer 110 parallel to the thickness direction of the first film layer 110, and the side of the second film layer 120 is a surface of the second film layer 120 parallel to the thickness direction of the second film layer 120; the first groove 10 and the second groove 20 are used to accommodate cooling materials.

[0047] The light-emitting structure layer 200 may be an organic light-emitting structure layer or an inorganic light-emitting structure layer. The light-emitting structure layer 200 may include a first electrode layer, a second electrode layer, and a light-emitting layer disposed between the first electrode layer and the second electrode layer. When the light-emitting structure layer 200 is an organic light-emitting structure layer, the light-emitting layer is an organic light-emitting layer, and a first functional layer may be included between the first electrode layer and the light-emitting layer, and a second functional layer may be included between the second electrode layer and the light-emitting layer. When the first electrode layer is a cathode and the second electrode layer is an anode, the first functional layer may include an electron injection layer, an electron transport layer, and a hole blocking layer, etc., and the second functional layer may include a hole injection layer, a hole transport layer, and an electron blocking layer, etc. When the first electrode layer is an anode and the second electrode layer is a cathode, the second functional layer may include an electron injection layer, an electron transport layer, and a hole blocking layer, etc., and the first functional layer may include a hole injection layer, a hole transport layer, and an electron blocking layer, etc.

[0048] The light-emitting structure layer 200 can serve as a light source for phototherapy, irradiating the treatment area and achieving a phototherapy cosmetic effect. The light-emitting structure layer 200 can be configured as a blue light-emitting structure layer or a red light-emitting structure layer, depending on the desired phototherapy effect. The specific luminous color of the light-emitting structure layer 200 is not specifically limited in this embodiment.

[0049] The first groove 10 and the second groove 20 are used to accommodate a cooling material. The cooling material can be a material with a low boiling point. After the cooling material enters the first groove 10 and the second groove 20, it vaporizes and absorbs heat to achieve a cooling effect. In addition, the cooling material can also be other materials, which are not specifically limited in this embodiment. For example, the cooling material can include materials such as perfluoropentane (PFP). The boiling point of PFP is low. Liquid PFP can be passed into the first groove 10 and the second groove 20. The liquid PFP vaporizes after reaching the boiling point. The vaporization process absorbs the surrounding heat to achieve a cooling effect. The corresponding cooling material can be selected according to the cooling temperature requirements, so that the cooling material can reduce the surrounding temperature to a lower temperature, thereby relieving pain at the phototherapy site during phototherapy, and can also cool the light-emitting structure layer 200.

[0050] The first groove 10 may be provided only in the first film layer 110 , the second groove 20 may be provided only in the second film layer 120 , or both the first groove 10 and the second groove 20 may be provided in the first film layer 110 and the second film layer 120 .

[0051] One of the first end 11 and the second end 12 of the first groove 10 serves as an injection port for the cooling material, and the other serves as an outlet port for the cooling material. The cooling material can be introduced into the first groove 10 at a predetermined flow rate, and the cooling rate can be adjusted by adjusting the flow rate to achieve a better cooling and analgesic effect. Furthermore, the first groove 10 may include other ends, which can serve as both an injection port and an outlet port for the cooling material. Multiple ends are interconnected, enabling further adjustment of the injection and outlet rates of the cooling material.

[0052] Similarly, the third end 21 and the fourth end 22 of the second groove 20 serve as an injection port for the cooling material, and as an outlet port for the cooling material. The cooling material can be introduced into the second groove 20 at a predetermined flow rate, and the cooling rate can be adjusted by adjusting the flow rate to achieve a better cooling and analgesic effect. Furthermore, the second groove 20 may include other ends, which can serve as both an injection port and an outlet port for the cooling material. Multiple ends can be interconnected to further adjust the injection and outlet rates of the cooling material.

[0053] also, Figure 3 is a top view of a second film layer provided by an embodiment of the present invention, Figure 2 and Figure 3 The structures of the first film layer 110 and the second film layer 120 are shown only as examples. Figures 1-3The first end 11 and the second end 12 of the first groove 10 can pass through the same side of the first film layer 110 or different sides of the first film layer 110, and can be specifically arranged according to the location where cooling and pain relief are required. The third end 21 and the fourth end 22 of the second groove 20 can pass through the same side of the second film layer 120 or different sides of the second film layer 120, and can be specifically arranged according to the location where cooling and pain relief are required.

[0054] In addition, one or more first grooves 10 can be set in the first film layer 110 according to the needs of the pain relief area, and one or more second grooves 20 can also be set in the second film layer 120. This embodiment does not specifically limit the number of grooves.

[0055] The phototherapy device provided by the embodiment of the present invention includes: a first substrate 100, a second substrate 300, and a light-emitting structure layer 200 located between the first substrate 100 and the second substrate 300. The first substrate 100 includes a first film layer 110 and a second film layer 120. A first groove 10 is provided on the surface of the first film layer 110 adjacent to the second film layer 120, and / or a second groove 20 is provided on the surface of the second film layer 120 adjacent to the first film layer 110. The first groove 10 and the second groove 20 are used to accommodate cooling materials. In the phototherapy device of the embodiment of the present invention, the light-emitting structure layer 200 is a light source for phototherapy. By providing cooling materials in the first groove 10 and the second groove 20, the cooling materials can cool the phototherapy position and the entire phototherapy device. Therefore, the phototherapy device of this embodiment can avoid excessive temperature when the phototherapy device is working, and can achieve the effect of cooling and relieving pain at the phototherapy position while performing phototherapy, thereby enriching the functions of the phototherapy device and improving the user experience.

[0056] Optional, Figure 4 This is a top view of another first film layer provided by an embodiment of the present invention, referring to Figure 4 The first groove 10 includes at least one first extension portion 01, at least one second extension portion 02 and at least one third extension portion 03. The first extension portion 01, the second extension portion 02 and the third extension portion 03 all extend to the side of the first film layer 110 and penetrate the side of the first film layer 110. Each first extension portion 01 is connected to a second extension portion 02 and / or a third extension portion 03; the first extension portion 01 is used to inject the first cooling material into the first groove 10, the second extension portion 02 is used to inject the second cooling material into the first groove 10, and the third extension portion 03 is used to discharge the material after the first cooling material and the second cooling material are mixed; wherein, the first cooling material and the second cooling material are cooled after mixing.

[0057] Figure 5 This is a top view of another second film layer provided by an embodiment of the present invention, referring to Figure 5The second groove 20 includes at least one fourth extension portion 04, at least one fifth extension portion 05 and at least one sixth extension portion 06. The fourth extension portion 04, the fifth extension portion 05 and the sixth extension portion 06 all extend to the side of the second film layer 120 and penetrate the side of the second film layer 120. Each fourth extension portion 04 is connected to a fifth extension portion 05 and / or a sixth extension portion 06; the fourth extension portion 04 is used to inject the first cooling material into the second groove 20, the fifth extension portion 05 is used to inject the second cooling material into the second groove 20, and the sixth extension portion 06 is used to discharge the material mixed with the first cooling material and the second cooling material.

[0058] The first cooling material may include perfluoropentane (PFP), and the second cooling material may include nitrogen. The first and second cooling materials, when mixed, can achieve a cooling effect. Because PFP has a boiling point between 28°C and 30°C, the introduction of dry nitrogen promotes its evaporation and vaporization. As PFP vaporizes, it absorbs surrounding heat, lowering the temperature of the surrounding area and thus achieving a cooling and analgesic effect. Furthermore, because PFP has a boiling point between 28°C and 30°C, it can maintain the operating temperature of the light-emitting structure layer, preventing the screen from overheating.

[0059] Specifically, nitrogen and PFP mix at the intersection of the first extension 01 and the second extension 02. The amount of nitrogen and PFP at this location is the largest, and the cooling rate after mixing is the fastest, resulting in the lowest temperature. Therefore, the intersection of the first extension 01 and the second extension 02 forms a pain relief zone. Multiple pain relief zones can be provided as needed.

[0060] Figure 6 This is a top view of another first film layer provided by an embodiment of the present invention, referring to Figure 6 There can be multiple first extensions 01 for injecting the first cooling material, and multiple second extensions 02 for injecting the second cooling material. Multiple first extensions 01 intersect with multiple second extensions 02 to form multiple pain-relieving zones, enhancing the pain-relieving effect. Furthermore, multiple third extensions 03 can be provided to discharge the mixed nitrogen and PFP. This allows for a faster discharge rate of the mixed nitrogen and PFP, allowing for better regulation of the nitrogen and PFP injection rate, and thus the cooling rate, thereby enhancing the pain-relieving effect.

[0061] Figure 7 This is a top view of another second film layer provided by an embodiment of the present invention, referring to Figure 7There can be multiple fourth extensions 04 for injecting the first cooling material, and multiple fifth extensions 05 for injecting the second cooling material. Multiple fourth extensions 04 intersect with multiple fifth extensions 05 to form multiple pain relief zones, enhancing the pain relief effect. Furthermore, multiple sixth extensions 06 can be provided to discharge the mixed nitrogen and PFP. This allows for a faster discharge rate of the mixed nitrogen and PFP, allowing for better regulation of the nitrogen and PFP injection rate, and thus the cooling rate, thereby enhancing the pain relief effect.

[0062] Optionally, the injection flow rate of the first cooling material is 200-600 μl / min, and the injection pressure of the second cooling material is 10-50 kPa.

[0063] Among them, the first cooling material is PFP, and the second cooling material is nitrogen. After PFP and liquid nitrogen are mixed, the liquid PFP evaporates rapidly, thereby achieving a cooling effect. The evaporation rate of PFP determines the temperature of the analgesic area after cooling, and the flow ratio between nitrogen and PFP determines the evaporation rate of PFP. The greater the evaporation rate of liquid PFP, the lower the temperature of the analgesic area after cooling. By adjusting the injection ratio and injection rate of PFP and nitrogen flowing into the evaporation chamber, the temperature of the analgesic area after cooling can be precisely controlled. By setting the injection flow rate of PFP to 200-600μl / min and the injection pressure of nitrogen to 10-50kpa, the temperature of the analgesic area is within a suitable temperature range, achieving a better cooling and analgesic effect without damaging the area to be analgesic.

[0064] Optional, Figure 8 This is a structural diagram of another phototherapy device provided by an embodiment of the present invention, referring to Figure 1 and Figure 8 , the first film layer 110 is provided with a first groove 10, and the second film layer 120 is not provided with a second groove ( Figure 8 ), or, the first film layer is not provided with the first groove, and the second film layer is provided with the first groove (not shown in the figure), or, the vertical projection of the first groove 10 on the first film layer 110 does not overlap with the second groove 20 ( Figure 1 ), the depths of the first groove 10 and the second groove 20 are both 10 μm-550 μm, and the widths of the first groove and the second groove are both 10 μm-100 μm; Figure 9 This is a structural diagram of another phototherapy device provided by an embodiment of the present invention, referring to Figure 9When the vertical projection of the first groove 10 on the second film layer 120 coincides with the second groove 20, the sum of the depths of the first groove 10 and the second groove 20 is 10 μm-550 μm, and the widths of the first groove 10 and the second groove 20 are both 10-100 μm; the thicknesses of the first film layer 110 and the second film layer 120 are both 60 μm-600 μm.

[0065] Among them, the depth and width of the first groove 10 and the second groove 20 affect the injection speed of the first cooling material and the second cooling material. By setting the depth and width of the first groove 10 and the second groove 20 to adopt the above-mentioned range, the adjustable range of the injection speed of the first cooling material and the second cooling material is larger, and the injection speed can be better adjusted to achieve a better cooling and analgesic effect.

[0066] Optional, Figure 10 This is a structural diagram of another phototherapy device provided by an embodiment of the present invention, referring to Figure 10 The phototherapy device also includes: a first cooling material injection device 400, a second cooling material injection device 500 and a temperature sensor 900; the temperature sensor 900 is arranged on the light-emitting side of the light-emitting structure layer 200, and the temperature sensor 900 is used to collect the surface temperature of the phototherapy device.

[0067] When the first film layer 110 is provided with a first groove 10, the first cooling material injection device 400 is connected to the first extension part 01 through a first injection pipeline, and the second cooling material injection device 500 is connected to the second extension part 02 through a second injection pipeline; the first cooling material injection device 400 is used to adjust the injection speed of the first cooling material into the first extension part 01 according to the surface temperature, and the second cooling material injection device 500 is used to adjust the injection speed of the second cooling material into the second extension part 02 according to the surface temperature.

[0069] The first cooling material injection device 400 can inject PFP into the first extension part 01 through the first injection pipeline and into the fourth extension part 04 through the third injection pipeline. The second cooling material injection device 500 can inject nitrogen into the second extension part 02 through the second injection pipeline and into the fifth extension part 05 through the fourth injection pipeline. The injection pipelines can be sealed to each extension part.

[0070] Specifically, the surface temperature of the phototherapy device collected by the temperature sensor 900 on the non-light-emitting side of the light-emitting structure layer 200, that is, the side of the phototherapy device adjacent to the user, is the temperature of the surface of the phototherapy device adjacent to the user's skin. When the surface temperature is too low, the injection speed of the first cooling material and the second cooling material can be reduced to reduce the cooling speed so that the surface temperature rises to an appropriate range. When the surface temperature is too high, the injection speed of the first cooling material and the second cooling material can be increased to increase the cooling speed so that the surface temperature falls to an appropriate range. By setting the temperature sensor 900, the surface temperature of the phototherapy device adjacent to the user can be accurately determined, thereby determining the temperature of the location to be relieved of pain, and adjusting the injection speed of the first cooling material and the second cooling material according to the surface temperature so that the surface temperature is within an appropriate range, thereby better relieving pain at the location to be relieved of pain.

[0076] Optional, continue to refer to Figure 10 The first substrate 100 is disposed on the non-light-emitting side of the light-emitting structure layer 200 ; the temperature sensor 900 is disposed on the surface of the second substrate 300 away from the light-emitting structure layer 200 .

[0077] Among them, the non-light-emitting side of the light-emitting structure layer 200 is the side that does not emit light. The light emitted by the light-emitting structure layer 200 is emitted through the second substrate 300. The surface of the second substrate 300 is away from the light-emitting structure layer 200, that is, the surface of the phototherapy device facing the user. The temperature sensor 900 is set on the surface of the second substrate 300 away from the light-emitting structure layer 200, so that the temperature sensor 900 is close to the position to be relieved. The collected temperature is the same as or not much different from the temperature of the position to be relieved, so that after the surface temperature measured by the temperature sensor 900 is adjusted to the injection speed of the cooling material, the pain in the position to be relieved can be better relieved.

[0078] Setting the first substrate 100 on the non-light-emitting side of the light-emitting structure layer 200 can prevent the cooling material in the first film layer 110 and the second film layer 120, as well as the unevenness of the first film layer 110 and the second film layer 120 from affecting the light emitting structure layer 200, thereby ensuring that the phototherapy device has a better phototherapy effect.

[0079] Optionally, the first substrate is a base substrate and the second substrate is a packaging substrate, or the first substrate is a packaging substrate and the second substrate is a base substrate.

[0080] When the first substrate is a base substrate and the second substrate is a packaging substrate, the first film layer and the second film layer can be flexible substrates, and the flexible substrate material can be an organic polymer such as polyester (PET), polyethylene naphthalate (PEN), polyimide (PI), etc. The following describes the manufacturing process of the phototherapy device with reference to the accompanying drawings:

[0081] Figure 11 is a top view of a glass substrate structure provided by an embodiment of the present invention, with reference to Figure 11 , the glass substrate 700 can be etched into a certain pattern by chemical etching or ion etching, such as Figure 11 The white part in the middle is a raised part. Three patterns are listed in the figure, and other patterns can also be etched. The raised part on the glass substrate 700 is used to shape the first groove of the first film layer. Figure 12 This is a structural diagram of another phototherapy device provided by an embodiment of the present invention, referring to Figure 12 A first film layer 110 is formed on a glass substrate 700 by slit coating, spin coating, or the like. A water-blocking layer 800 is deposited on the side of the base substrate away from the glass substrate 700 to prevent water and oxygen from corroding the light-emitting structure layer 200. The water-blocking layer 800 is made of any one or a combination of at least two of silicon nitride, silicon oxide, silicon oxynitride, epoxy resin, or polyolefin, and is prepared by one or a combination of ALD, PECVD, IJP, screen printing, or sputtering.

[0082] Then, a first electrode layer 210 is prepared. The material of the first electrode layer 210 can be indium tin oxide (ITO) and / or indium zinc oxide (IZO), or indium tin oxide (ITO) / silver (Ag) / indium tin oxide (ITO); then, an organic light-emitting structure layer 220 is prepared. The organic light-emitting structure layer 220 includes a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, an electron blocking layer, an electron transport layer and an electron injection layer stacked in sequence; then, a second electrode layer 230 is prepared. The material of the third electrode 230 includes at least one of silver (Ag), aluminum (Al) and magnesium (Mg).

[0083] Then prepare the second substrate 300 (packaging substrate). The function of the packaging substrate is to prevent water and oxygen from corroding the light-emitting structure layer 200. The material of the packaging substrate includes any one or a combination of at least two of silicon nitride, silicon oxide, silicon oxynitride, epoxy resin or polyolefin, and the preparation method is one or more of ALD, PECVD, IJP, screen printing or sputtering.

[0084] Then, attach the temperature sensor 900 to the packaging substrate. Finally, remove the glass substrate 700 and glue the second film layer to the first film layer. The bonding area is the protrusion of the first film layer, and the second film layer completely covers the surface of the first film layer. This creates a first groove between the first and second film layers. Alternatively, prepare the second film layer using the same method as the first film layer, and after forming the second groove in the second film layer, attach it to the first film layer.

[0085] Specifically, the first film layer 110 can be separated from the glass substrate 700 by laser, or a sacrificial layer can be added between the first film layer 110 and the glass substrate 700, and the bonding between the sacrificial layer and the first film layer 110 can be changed mechanically or by immersing in water or an organic solvent, or the sacrificial layer can be removed to achieve separation of the first film layer 110 from the sacrificial layer.

[0086] When the first substrate is a packaging substrate and the second substrate is a base substrate, the second substrate, the light-emitting structure layer and the first substrate can be directly prepared in sequence on the flat glass substrate surface. When preparing the first substrate, a first packaging material layer can be first made on the surface of the light-emitting structure layer, and then a first groove in the shape of the first packaging material layer can be etched on the surface of the first packaging material layer to form a first film layer with a first groove, and then the second film layer is attached to the surface of the first film layer by glue. The second film layer can be made of a flexible substrate material or other materials. The second film layer with a second groove can be prepared on a glass substrate with a convex structure. It should be noted that in order to ensure the packaging effect of the packaging substrate on the light-emitting structure layer 200, the packaging substrate can be provided with a plurality of packaging film layers, and one or more other packaging film layers can be provided on the side of the first packaging material layer adjacent to the light-emitting structure layer 200.

[0087] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved. This is not limited herein.

[0088] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
