[0046] In recent years, with continuous technological advancements and economic development, beauty devices have become a popular part of women's lives. Simultaneously, due to the discovery of deep red light's cell repair capabilities, phototherapy products are increasingly being used in the medical field to promote wound healing, treat skin inflammation, and promote hair growth and beauty. Currently, beauty devices on the market primarily use LEDs as their light source. The advantages of LED light sources lie in their safety, ease of operation, and the therapeutic effects of specific wavelengths. LED beauty devices are simple to operate, allowing users to use them at home. However, LEDs are arranged in a discrete array of LED beads, resulting in relatively poor light uniformity.

[0047] Users want to avoid interfering with other activities while using beauty devices, such as looking at their phones, working, or doing housework. To prevent eye damage from light during the beauty process, eye protection is necessary. A shield should be placed near the eyes to protect them from the light. As shown in Figure 1, typical face mask beauty devices use a separate eye shield for protection, which can obstruct the user's view of the outside world during the treatment, resulting in poor convenience and user experience.

[0048] Based on this, the present invention provides a light-emitting panel 100. As shown in Figures 1 to 15, the light-emitting panel 100 is used in a mask-type beauty device. The light-emitting panel 100 is provided with an eye-avoiding opening 1001, and an anti-peeping area 1002 is provided around the eye-avoiding opening 1001. The light-emitting panel 100 includes a driving back plate 10, a pixel definition layer, a plurality of light-emitting devices 160, and at least two light-shielding layers 22. The pixel definition layer is located on one side of the driving back plate 10, and a plurality of pixel openings 151 are provided on the pixel definition layer. The plurality of light-emitting devices 160 are respectively located in different pixel openings 151. At least two light-shielding layers 22 are located on the side of the pixel definition layer away from the driving back plate 10. The light-shielding layers 22 are located in the anti-peeping area 1002, and light-transmitting openings 2201 are provided on the light-transmitting layers 2201. The orthographic projection of the light-transmitting openings 2201 on the driving back plate 10 overlaps with the orthographic projection of the light-emitting devices 160 on the driving back plate 10.

[0049] The light-emitting panel 100 is provided with an eye-avoidance opening 1001, and an anti-peeping area 1002 is provided around the eye-avoidance opening 1001. The light-emitting panel 100 includes a light-emitting device 160 and at least two light-shielding layers 22. The light-shielding layers 22 are located in the anti-peeping area 1002, and the light-shielding layers 22 are provided with light-transmitting openings 2201. The orthographic projection of the light-transmitting openings 2201 on the drive back plate 10 overlaps with the orthographic projection of the light-emitting device 160 on the drive back plate 10. Large-angle emitted light can be absorbed by at least two light-shielding layers 22, while small-angle emitted light is emitted through the light-transmitting openings 2201. The light-shielding layers 22 narrow the emitted light from the anti-peeping area 1002 along the light emission direction. When the mask-type beauty device is close to the face, no emitted light shines into the eyes at the eye position, which plays a role in protecting the eyes and can avoid affecting the user's ability to see external things during beauty treatments, resulting in better convenience and user experience.

[0050] The light-emitting panel 100 of the present invention will be described in detail below with reference to specific embodiments.

[0051] As shown in Figure 1, the light-emitting panel 100 may generally include a substrate 11 and a driving circuit layer 13. The driving circuit layer 13 is disposed on one side of the substrate 11. The light-emitting panel 100 may also include a buffer layer 12, which is disposed between the substrate 11 and the driving circuit layer 13.

[0052] The substrate 11 can be an inorganic material or an organic material. For example, in one embodiment of the present invention, the substrate 11 can be made of glass materials such as soda-lime glass, quartz glass, or sapphire glass, or it can be made of metal materials such as stainless steel, aluminum, or nickel.

[0053] In another embodiment of the present invention, the substrate 11 may also be a flexible substrate 11, for example, the material of the substrate 11 may be polyimide (PI). The substrate 11 may also be a composite of multiple materials. For example, in one embodiment of the present invention, the substrate 11 may include a bottom film, a pressure-sensitive adhesive layer, a first polyimide layer and a second polyimide layer stacked sequentially.

[0054] The driving circuit layer 13 is provided with a driving circuit for driving the light-emitting device 160. The driving circuit is located in the display area, and any driving circuit may include a transistor, which may be a thin-film transistor (TFT). The TFT may be selected from top-gate TFTs, bottom-gate TFTs, or dual-gate TFTs. Taking a top-gate TFT as an example, the driving circuit layer 13 may include a first active layer 131, a first gate insulating layer 1321, a first gate 1331 layer, a second gate insulating layer 1322, a second gate 1332 layer, and a first source / drain metal layer, sequentially disposed along a direction away from the substrate 11, wherein:

[0055] The first active layer 131 is disposed on one side of the substrate 11. The material of the first active layer 131 can be amorphous silicon semiconductor material, low-temperature polycrystalline silicon semiconductor material, metal oxide semiconductor material, organic semiconductor material, or other types of semiconductor material. Therefore, the thin film transistor can be an N-type thin film transistor or a P-type thin film transistor. The first active layer 131 may include a channel region and two doped regions of different doping types located on both sides of the channel region.

[0056] The first gate insulating layer 1321 is disposed on the side of the active layer 131 away from the substrate 11. The first gate insulating layer 1321 can cover the active layer 131 and the substrate 11. The first gate 1331 layer can include the first gate 1331. The first gate 1331 is disposed on the side of the first gate insulating layer 1321 away from the substrate 11 and is directly opposite to the active layer 131. That is, the projection of the first gate 1331 on the substrate 11 is located within the projection range of the active layer 131 on the substrate 11. For example, the projection of the first gate 1331 on the substrate 11 coincides with the projection of the channel region of the active layer 131 on the substrate 11. The second gate insulating layer 1322 is disposed on the side of the first gate 1331 away from the substrate 11. The second gate insulating layer 1322 can cover the first gate 1331 and the first gate insulating layer 1321. The second gate 1332 layer can include the second gate 1332, which is disposed on the side of the second gate insulating layer 1322 away from the substrate 11 and is directly opposite the active layer 131. The materials of the first gate insulating layer 1321 and the second gate insulating layer 1322 are both insulating materials such as silicon oxide.

[0057] The thin-film transistor may further include an interlayer dielectric layer 134, which is disposed on the side of the second gate 1332 away from the substrate 11, and may cover the second gate 1332 and the second gate insulating layer 1322. A first source / drain metal layer is disposed on the surface of the interlayer dielectric layer 134 away from the substrate 11, and may include a first source 135 and a drain 136, which are connected to the first active layer 131. For example, the first source 135 and the drain 136 are respectively connected to two doped regions of the corresponding first active layer 131 through vias. A protective layer 137 may also be provided on the side of the first source 135 away from the substrate 11, and the protective layer 137 covers the first source 135 and the drain 136. The driving circuit layer 13 may also include a planarization layer group 139, which includes a first planarization layer 1391. The first planarization layer 1391 is disposed on the side of the protective layer 137 away from the substrate 11, and the first planarization layer 1391 covers the protective layer 137.

[0058] The driving circuit layer 13 may further include a second source / drain metal layer, which is disposed on the side of the first planarization layer 1391 away from the substrate 11. The second source / drain metal layer may include a second source 138, which is connected to the first source 135. The planarization layer group 139 may further include a second planarization layer 1392, which is disposed on the side of the second source 138 away from the substrate 11. The second planarization layer 1392 covers the second source 138 and the first planarization layer 1391.

[0059] The light-emitting panel 100 may further include a pixel defining layer 15 and a light-emitting layer 16. The pixel defining layer 15 is disposed on the side of the first planarization layer 1391 or the second planarization layer 1392 away from the array substrate. The pixel defining layer 15 includes a plurality of pixel defining portions 152, and a pixel opening 151 is formed between two adjacent pixel defining portions 152. The light-emitting layer 16 may include a plurality of light-emitting devices 160, and the light-emitting devices 160 are organic light-emitting diodes, with more uniform light distribution.

[0060] Multiple light-emitting devices 160 are respectively disposed within different pixel openings 151. Each light-emitting device 160 may include a pixel electrode 161, a light-emitting unit 162, and a common electrode 163. The pixel electrode 161 is located on the surface of the first planarization layer 1391 or the second planarization layer 1392 away from the substrate 11. The light-emitting unit 162 is disposed on the surface of the pixel electrode 161 away from the substrate 11. The common electrode 163 is disposed on the surface of the light-emitting unit 162 away from the substrate 11. The light-emitting unit 162 can be driven to emit light through the pixel electrode 161 and the common electrode 163 to display an image.

[0061] Pixel electrode 161 is connected to either the first source 135 or the second source 138. A pixel defining layer 15 is provided on the side of pixel electrode 161 away from the substrate 11. When the thin-film transistor includes only the first source 135, pixel electrode 161 is connected to the first source 135, and pixel defining layer 15 covers pixel electrode 161 and the first planarization layer 1391. When the thin-film transistor also includes the second source 138, pixel electrode 161 is connected to the second source 138, and pixel defining layer 15 covers pixel electrode 161 and the second planarization layer 1392.

[0062] The common electrode 163 can serve as the cathode, and the pixel electrode 161 can serve as the anode. Light emission from the light-emitting unit 162 can be driven by applying a signal to the pixel electrode 161; the specific light emission principle will not be detailed here. The light-emitting unit 162 may contain electroluminescent organic light-emitting materials and can be formed using processes such as vapor deposition. For example, the light-emitting unit 162 may include a hole injection layer, a hole transport layer, a light generation layer, an electron transport layer, and an electron injection layer sequentially stacked on the pixel electrode 161. It should be noted that 600nm-700nm is the wavelength range where cosmetic therapeutic effects are most concentrated; therefore, the light-emitting device 160 is used to emit red emitted light. Considering the effective depth of the emitted light during cosmetic procedures, the depth of the red light band is 6mm. It should be noted that the depth of light refers to the ratio of radiation or light that is scattered or absorbed along its transmission path.

[0063] Furthermore, the light-emitting panel 100 of the present invention may also include an encapsulation layer 17, which is disposed on the side of the light-emitting layer 16 away from the substrate 11, thereby covering the light-emitting layer 16 and preventing water and oxygen corrosion. The encapsulation layer 17 may be a single-layer or multi-layer structure, and the material of the encapsulation layer 17 may include organic or inorganic materials, without special limitation. In this embodiment, the encapsulation layer 17 may include a first inorganic encapsulation layer 171, an organic encapsulation layer 172, and a second inorganic encapsulation layer 173. The first inorganic encapsulation layer 171 is disposed on the side of the light-emitting layer 16 away from the substrate 11, the organic encapsulation layer 172 is disposed on the side of the first inorganic encapsulation layer 171 away from the substrate 11, and the second inorganic encapsulation layer 173 is disposed on the side of the organic encapsulation layer 172 away from the substrate 11.

[0064] The light-emitting panel 100 also includes a touch control layer 18, which can be a mutual capacitive touch control layer. The touch control layer 18 includes a first touch control layer 181 and a second touch control layer 182. The first touch control layer 181 is a metal mesh layer (MM), and the second touch control layer 182 is a bridge metal layer (BM). The metal mesh is located in the display area and can be divided into touch-driving (Tx) metal mesh and touch-sensing (Rx) metal mesh according to the horizontal and vertical directions. One of the touch-sensing (Rx) metal mesh and the touch-driving (Tx) metal mesh is interconnected, while the other is connected through the bridge metal layer.

[0065] The first tactile control layer 181 is disposed on the side of the substrate 11 away from the encapsulation layer 17, and the second tactile control layer 182 is disposed between the first tactile control layer 181 and the encapsulation layer 17. The tactile control layer 18 may further include a touch blocking layer 183 and a touch isolating layer 184, with the touch blocking layer 183 disposed between the encapsulation layer 17 and the second tactile control layer 182, and the touch isolating layer 184 disposed between the first tactile control layer 181 and the second tactile control layer 182.

[0066] The first tactile control layer 181 may include a plurality of first touch units 1811, which are spaced apart. The orthographic projection of the first touch unit 1811 on the substrate 11 is located between the orthographic projections of two adjacent light-emitting devices 160 on the substrate 11. The second tactile control layer 182 may include a plurality of second touch units 1821, whose orthographic projections on the substrate 11 overlap with the orthographic projections of the first touch units 1811 on the substrate 11.

[0067] As shown in Figures 2 to 4, the light-emitting panel 100 has an eye-avoidance opening 1001, and the light-emitting area surrounding the eye-avoidance opening 1001 has a privacy zone 1002. The light-emitting panel 100 may also include a light-shielding layer 22, which is located in the privacy zone 1002. The light-shielding layer 22 is located on the side of the encapsulation layer 17 away from the driving backplate 10, and has a light-transmitting opening 2201. The orthographic projection of the pixel opening 151 on the driving backplate 10 is located within the orthographic projection of the light-transmitting opening 2201 on the driving backplate 10. The emitted light from each light-emitting device 160 of the light-emitting layer 16 exits through the corresponding light-transmitting opening 2201. The emitted light with a small viewing angle exits through the light-transmitting opening 2201, while the emitted light with a large viewing angle is absorbed by the portion other than the light-transmitting opening 2201. When the mask-type beauty device is in close contact with the face, no emitted light is directed towards the eyes at the eye position, thus protecting the eyes. The area excluding the privacy zone 1002 is the normal zone 1003, and the normal zone 1003 is not equipped with a light-shielding layer 22.

[0068] The light-shielding layer 22 includes at least two light-shielding layers 22, and the orthographic projections of the light-transmitting openings 2201 on any two light-shielding layers 22 on the driving backplate 10 overlap with each other. As shown in FIG5, it includes a first light-shielding layer 221 and a second light-shielding layer 222. The first light-shielding layer 221 is disposed on the side of the pixel definition layer away from the driving backplate 10, and the second light-shielding layer 222 is disposed on the side of the first light-shielding layer 221 away from the driving backplate 10. The first light-shielding layer 221 has a first light-transmitting opening 2211, and the second light-shielding layer 222 has a second light-transmitting opening 2221. The orthographic projection of the second light-transmitting opening 2221 on the driving backplate 10 overlaps with the orthographic projection of the first opening on the driving backplate 10. As shown in Figure 6, the light-shielding layer 22 may further include a third light-shielding layer 223. The third light-shielding layer 223 has a third light-transmitting opening 2231. The orthographic projection of the third light-transmitting opening 2231 on the driving back plate 10 overlaps with the orthographic projection of the second opening on the driving back plate 10. The light-shielding layer 22 has no more than four layers to avoid peeling between the layers of the light-emitting panel 100 due to a large number of light-shielding layers 22.

[0069] The light-emitting panel 100 also includes a plurality of microlenses 23, which are disposed on the side of the light-shielding layer 22 away from the driving backplate 10. The orthographic projection of the microlenses 23 on the driving backplate 10 covers the orthographic projection of the light-transmitting opening 2201 on the driving backplate 10. The ratio of the thickness to the width of the microlens 23 is greater than 0 and less than or equal to 1. The ideal range for the ratio of the thickness L2 to the width L1 of the microlens 23 is between 0.3 and 1. The refractive index of the microlens 23 is greater than or equal to 1.6. The distance between two adjacent pixel openings 151 is 100 to 1000 μm, and the distance between two adjacent microlenses 23 can also be 100 to 1000 μm.

[0070] As shown in Figure 7, the light-emitting panel 100 may further include a light control film 25. The orthographic projection of the light control film 25 onto the driving backplate 10 covers the orthographic projection of the privacy area 1002 onto the driving backplate 10. The portion of the light-emitting area other than the privacy area 1002 is the normal area 1003, which is not provided with the light control film 25. As shown in Figures 8 and 9, the light control film 25 includes multiple grating strips 251 arranged parallel to each other. The thickness t of the grating strips 251 is 0.2–1 mm, the width w is 30–50 mm, the distance d between adjacent grating strips 251 is 50–1000 μm, and the refractive index of the grating strips 251 is greater than or equal to 1.6. A slit is formed between two adjacent grating strips 251. The slit only allows light rays perpendicular to the normal direction of the plane of the light control film 25 to exit. The light control film 25 can also control the direction of light emission to protect the eyes.

[0071] In this embodiment, the included angle between the normal direction of the light control film 25 plane and the eye line of sight direction is 5 to 45°. As the included angle between the normal direction of the light control film 25 plane and the eye line of sight direction increases, the emitted light gradually weakens. As shown in FIG. 10, when the included angle θ between the normal direction of the light control film 25 and the eye line of sight direction is 0°, the light transmission area is the largest and the non-transmission area is the smallest. As shown in FIG. 11, when the included angle θ between the normal direction and the eye line of sight direction is 10°, the light transmission area is smaller than when the included angle θ between the normal direction and the eye line of sight direction is 0°, and the non-transmission area is larger than when the included angle θ between the normal direction and the eye line of sight direction is 0°. As shown in FIG. 12, when the included angle θ between the normal direction of the light control film 25 and the eye line of sight direction is 30°, the light transmission area is 0 and the non-transmission area is the largest, that is, it is completely opaque. The brightness of the emitted light observed by the eye can be controlled by the included angle θ between the normal direction of the light control film 25 and the eye line of sight direction.

[0072] As shown in FIGS. 5, FIG. 6 and FIG. 13, the light emitting panel 100 further includes a lens protection layer 24. The lens protection layer 24 covers the side of the plurality of microlenses 23 away from the driving backplane 10. The lens protection layer 24 fills between adjacent two microlenses 23 and contacts the light shielding layer 22. The lens protection layer 24 can play a certain protective role for the lens and flatten the surface of the microlenses 23 away from the driving backplane 10.

[0073] As shown in FIG. 14, the lens protection layer 24 includes a first protection portion 241. The first protection portion 241 fills between adjacent two microlenses 23, and the refractive index of the first protection portion 241 is less than that of the microlenses 23. When the emitted light of the light emitting device 160 at a large viewing angle enters the first protection portion 241 from the microlenses 23, the incident angle is A1 and the refraction angle is A2. Since the refractive index of the first protection portion 241 is less than that of the microlenses 2, 3, so A2 > A1. The emitted light at a large viewing angle converges towards the middle after entering the first protection portion 241, which can further prevent the emitted light from hitting the eyes and has a better protection effect on the eyes.

[0074] The lens protection layer 24 further includes a second protection portion 242. The second protection portion 242 is provided on the side of the microlenses 23 away from the driving backplane 10, and the second protection portion 242 is provided between adjacent two first protection portions 241. The refractive index of the second protection portion 242 is greater than that of the microlenses 23. When the emitted light of the light emitting device 160 at a small viewing angle enters the second protection portion 242 from the microlenses 23, the incident angle is B1 and the refraction angle is B2. Since the refractive index of the first protection portion 241 is less than that of the microlenses 23, so B2 < B1. The emitted light at a small viewing angle converges towards the middle after entering the second protection portion 242, which can further prevent the emitted light from hitting the eyes and has a better protection effect on the eyes.

[0075] To ensure that the outgoing light rays at a large viewing angle are all incident on the first protection part 241, causing the outgoing light rays at a large viewing angle to converge towards the middle, the included angle C between the connection line of the center of the microlens 23 and the edge of the first protection part 241 and the bottom surface of the microlens 23 is set to be less than or equal to \(60^{\circ}\).

[0076] As shown in FIG. 15, the second protection part 242 can also be provided to cover the first protection part 241, that is, the first protection part 241 covers the first protection part 241 between the microlens 23 and the adjacent microlens 23. The refractive index of the second protection part 242 is greater than that of the first protection part 241. After the outgoing light at a large viewing angle is first converged by the first protection part 241, it enters the second protection part 242 from the first protection part 241. The incident angle is \(A3\), and the refraction angle is \(A4\), \(A4 < A3\). The outgoing light rays at a large viewing angle after the first convergence are converged a second time, further preventing the outgoing light rays at a large viewing angle from reaching the eyes at the eye position and playing a better protective role for the eyes.

[0077] The embodiment of the present invention also provides a mask-type beauty device. As shown in FIGS. 3 and 7, the mask-type beauty device can include the light-emitting panel 100 of any one of the above embodiments of the present invention. The specific structure and beneficial effects of the light-emitting panel 100 have been described in detail above, so they will not be elaborated here.

[0078] The mask-type beauty device can also include a housing 200. The housing 200 can be provided with a fixing groove, and the light-emitting panel 100 can be installed in the fixing groove. To facilitate fixation with the face, lugs can also be provided on both sides of the housing 200, and strip-shaped holes can be provided on the lugs. Elastic bands can be provided in the strip-shaped holes, and the elastic bands are used to fix with the user's head.

[0079] It should be noted that in addition to the light-emitting panel 100, the mask-type beauty device also includes other necessary components and compositions, such as a circuit board, a power cord, etc. Those skilled in the art can supplement them accordingly according to the specific use requirements of the mask-type beauty device, which will not be elaborated here.
