[0059] In recent years, with the continuous progress of science and technology and the continuous development of economy, beauty instrument has become a popular part of the lives of women. At the same time, with the discovery of the cell repair ability of deep red light, light therapy products are increasingly used in the medical field to promote wound healing, skin inflammation treatment and hair growth beauty, etc. The beauty instrument on the market at present takes LED as the main light source. The advantage of LED light source is its safety, simple operation and specific wavelength treatment effect. LED beauty instrument is simple to operate, and users can use it at home. However, LED is a discrete lamp bead arrangement, and the light uniformity is poor.

[0060] 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 the light during the beauty process, eye protection is necessary. Areas close to the eyes should be shielded to protect them from the light's harmful effects. Figure 1 As shown, typical face mask beauty devices only have an additional eye mask for eye protection, which affects the user's ability to see the outside world during the beauty treatment, resulting in poor convenience and experience.

[0061] Based on this, the present invention provides a light-emitting panel 100. For example... Figures 1 to 15 As shown, the light-emitting panel 100 is used in a mask-type beauty device. The light-emitting panel 100 has 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 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 a light-transmitting opening 2201 is provided on the light-transmitting layer 2201. The orthographic projection of the light-transmitting opening 2201 on the driving back plate 10 overlaps with the orthographic projection of the light-emitting device 160 on the driving back plate 10.

[0062] 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.

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.

[0065] The substrate 11 can be a substrate of inorganic material or a substrate of organic material. For example, in an embodiment of the present application, the material of the substrate 11 can be a glass material such as soda-lime glass, quartz glass, sapphire glass, or a metal material such as stainless steel, aluminum, nickel, etc.

[0066] In another embodiment of the present application, the substrate 11 can also be a flexible substrate 11, for example, the material of the substrate 11 can be polyimide (PI).

The first gate 1331 can be arranged on the side of the first gate insulating layer 1321 away from the substrate 11, and is opposite to the active layer 131, i.e., the projection of the first gate 1331 on the substrate 11 is 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 arranged on the side of the first gate 1331 away from the substrate 11, and can cover the first gate 1331 and the first gate insulating layer 1321.

The materials of the first gate insulating layer 1321 and the second gate insulating layer 1322 are both insulating materials such as silicon oxide.

[0070] The thin film transistor can further include an interlayer dielectric layer 134 arranged on the side of the second gate 1332 away from the substrate 11, and the interlayer dielectric layer 134 can cover the second gate 1332 and the second gate insulating layer 1322.

A protective layer 137 can be arranged 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 planarization layer group 139 can further include a second planarization layer 1392 arranged on the side of the second source 138 away from the substrate 11, and the second planarization layer 1392 covers the second source 138 and the first planarization layer 1391.

[0072] The light-emitting panel 100 can further include a pixel defining layer 15 and a light-emitting layer 16.

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 by the pixel electrode 161 and the common electrode 163, so as to display an image.

[0074] The pixel electrode 161 is connected to the first source 135 or the second source 138. The pixel electrode 161 is disposed on the side of the pixel defining layer 15 away from the substrate 11. When the thin film transistor only includes the first source 135, the pixel electrode 161 is connected to the first source 135, and the pixel defining layer 15 covers the pixel electrode 161 and the first planarization layer 1391. When the thin film transistor further includes the second source 138, the pixel electrode 161 is connected to the second source 138, and the pixel defining layer 15 covers the pixel electrode 161 and the second planarization layer 1392.

For example, the light-emitting unit 162 can include a hole injection layer, a hole transport layer, a light generating layer, an electron transport layer, and an electron injection layer, which are sequentially stacked on the pixel electrode 161. It should be noted that 600-700 nm is the most concentrated waveband of cosmetic efficacy, so the light-emitting device 160 is used to emit red light. Considering the effective depth of the emitted light in the cosmetic treatment, the depth of the red light waveband is 6 mm.

[0080] As Figures 2 to 4As shown, the light-emitting panel 100 is provided with an eye-avoiding opening 1001, and the light-emitting region around the periphery of the eye-avoiding opening 1001 is provided with a privacy area 1002. The light-emitting panel 100 can further include a light-shielding layer 22, which is located in the privacy area 1002 and is arranged on the side of the encapsulation layer 17 away from the driving backboard 10. The light-shielding layer 22 is provided with a light-transmitting opening 2201, and the orthographic projection of the pixel opening 151 on the driving backboard 10 is located within the orthographic projection of the light-transmitting opening 2201 on the driving backboard 10. The emitted light of each light-emitting device 160 of the light-emitting layer 16 exits through the corresponding light-transmitting opening 2201. The light with a small viewing angle exits through the light-transmitting opening 2201, while the light with a large viewing angle is absorbed by the part other than the light-transmitting opening 2201. When the mask-type beauty instrument is close to the face, no light exits towards the eyes at the eye position, thereby protecting the eyes. The part of the light-emitting region other than the privacy area 1002 is a normal area 1003, and the normal area 1003 is not provided with the light-shielding layer 22.

[0081] The light-shielding layer 22 includes at least two layers of light-shielding layers 22, and the orthographic projections of the light-transmitting openings 2201 on the driving backboard 10 of any two layers of light-shielding layers 22 overlap with each other. As shown in FIG. 2B, Figure 5 The light-shielding layer 22 includes a first light-shielding layer 221 and a second light-shielding layer 222. The first light-shielding layer 221 is arranged on the side of the pixel definition layer away from the driving backboard 10, and the second light-shielding layer 222 is arranged on the side of the first light-shielding layer 221 away from the driving backboard 10. The first light-shielding layer 221 is provided with a first light-transmitting opening 2211, and the second light-shielding layer 222 is provided with a second light-transmitting opening 2221. The orthographic projection of the second light-transmitting opening 2221 on the driving backboard 10 overlaps with the orthographic projection of the first light-transmitting opening 2211 on the driving backboard 10. As shown in FIG. 2C, Figure 6 The light-shielding layer 22 can further include a third light-shielding layer 223, and the third light-shielding layer 223 is provided with a third light-transmitting opening 2231. The orthographic projection of the third light-transmitting opening 2231 on the driving backboard 10 overlaps with the orthographic projection of the second light-transmitting opening 2221 on the driving backboard 10. The light-shielding layer 22 has less than or equal to four layers, so as to avoid peeling between the layers of the light-emitting panel 100 due to too many layers of the light-shielding layer 22.

[0082] The light-emitting panel 100 further includes a plurality of microlenses 23, which are arranged on the side of the light-shielding layer 22 away from the driving backboard 10. The orthographic projection of the microlens 23 on the driving backboard 10 covers the orthographic projection of the light-transmitting opening 2201 on the driving backboard 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 ratio of the thickness L2 to the width L1 of the microlens 23 is more ideal in the range of 0.3-1. The refractive index of the microlens 23 is greater than or equal to 1.6. The distance between adjacent two pixel openings 151 is 100-1000 μm, and the distance between adjacent two microlenses 23 can be 100-1000 μm.

[0083] As shown in Figure 7 , the light-emitting panel 100 can further include a light control film 25, a normal projection of which on the driving backboard 10 covers a normal projection of the peep-proof area 1002 on the driving backboard 10. The part of the light-emitting area other than the peep-proof area 1002 is a normal area 1003, which is not provided with the light control film 25. As shown in Figure 8 and Figure 9 , the light control film 25 includes a plurality of grating strips 251, which are arranged in parallel to each other. The thickness t of the grating strip 251 is 0.2-1 mm, the width w of the grating strip 251 is 30-50 mm, the distance d between adjacent grating strips 251 is 50-1000 μm, and the refractive index of the grating strip 251 is greater than or equal to 1.6. A slit is formed between two adjacent grating strips 251, which allows only the light rays perpendicular to the normal direction of the plane of the light control film 25 to be emitted. The light control film 25 can also control the direction of the emitted light, so as to protect the eyes.

[0084] In the embodiment, the angle between the normal direction of the plane of the light control film 25 and the line of sight of the eyes is 5-45°. As the angle between the normal direction of the plane of the light control film 25 and the line of sight of the eyes increases, the emitted light gradually weakens. As shown in Figure 10 , when the angle θ between the normal direction of the light control film 25 and the line of sight of the eyes is 0°, the light transmission area is the largest, and the non-transmission area is the smallest. As shown in Figure 11 , when the angle θ between the normal direction of the light control film 25 and the line of sight of the eyes is 10°, the light transmission area is smaller than that when the angle θ between the normal direction of the light control film 25 and the line of sight of the eyes is 0°, and the non-transmission area is larger than that when the angle θ between the normal direction of the light control film 25 and the line of sight of the eyes is 0°. As shown in Figure 12 , when the angle θ between the normal direction of the light control film 25 and the line of sight of the eyes is 30°, the light transmission area is 0, and the non-transmission area is the largest, i.e. the light is completely not transmitted. The angle θ between the normal direction of the light control film 25 and the line of sight of the eyes can be used to control the brightness of the emitted light observed by the eyes.

[0085] As shown in Figure 5 , Figure 6 and Figure 13 , the light-emitting panel 100 further includes a lens protection layer 24, which covers the side of the plurality of micro-lenses 23 away from the driving backboard 10, fills the space between two adjacent micro-lenses 23, and is in contact with the light-shielding layer 22. The lens protection layer 24 can protect the lenses and make the side of the micro-lenses 23 away from the driving backboard 10 flat.

[0086] As shown in Figure 14As shown, the lens protection layer 24 includes a first protection part 241. The first protection part 241 is filled between two adjacent micro-lenses 23, and the refractive index of the first protection part 241 is less than that of the micro-lens 23. When the light rays emitted from the light-emitting device 160 at a large viewing angle enter the first protection part 241 from the micro-lens 23, the incident angle is A1 and the refraction angle is A2. Since the refractive index of the first protection part 241 is less than that of the micro-lens 23, A2 > A1. After the light rays emitted at a large viewing angle enter the first protection part 241, they converge towards the middle, which can further prevent the light rays from hitting the eyes, providing better eye protection.

[0087] The lens protection layer 24 further includes a second protection part 242. The second protection part 242 is provided on the side of the micro-lens 23 away from the driving backplane 10, and the second protection part 242 is provided between two adjacent first protection parts 241. The refractive index of the second protection part 242 is greater than that of the micro-lens 23. When the light rays emitted from the light-emitting device 160 at a small viewing angle enter the second protection part 242 from the micro-lens 23, the incident angle is B1 and the refraction angle is B2. Since the refractive index of the first protection part 241 is less than that of the micro-lens 23, B2 < B1. After the light rays emitted at a small viewing angle enter the second protection part 242, they converge towards the middle, which can further prevent the light rays from hitting the eyes, providing better eye protection.

[0088] To ensure that the light rays emitted at a large viewing angle are all incident on the first protection part 241, causing the light rays emitted at a large viewing angle to converge towards the middle, the angle C between the connection line of the center of the micro-lens 23 and the edge of the first protection part 241 and the bottom surface of the micro-lens 23 is set to be less than or equal to 60 degrees.

[0089] As Figure 15 shown, it is also possible to set the second protection part 242 to cover the first protection part 241, that is, the first protection part 241 covers the micro-lens 23 and the first protection part 241 between adjacent micro-lenses 23. The refractive index of the second protection part 242 is greater than that of the first protection part 241. After the light rays emitted at a large viewing angle are first converged by the first protection part 241, they enter 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 light rays emitted at a large viewing angle after the first convergence are secondarily converged, further preventing the light rays emitted at a large viewing angle from hitting the eyes at the eye position, providing better protection for the eyes.
