[0063] In one embodiment, see Figure 1 , a display module 100 is provided, and the display module 100 includes a pixel layer 110, a detection module 120 and a control module 130.

[0064] The pixel layer 110 can be used to emit display light and medical light. Accordingly, in the pixel layer 110, the module that can emit display light is the display light emitting module 111, and the module that can emit medical light is the phototherapy light emitting module 112. It can be understood that the pixel layer 110 has both phototherapy and display functions. The phototherapy function and the display function can work at the same time, or one can work while the other stops.

[0065] The display light emitting module 111 can be used for light display. The light therapy light emitting module 112 can be used for light therapy beauty. Exemplarily, the display light may include visible light (for example, light with a wavelength of 400 nanometers to 800 nanometers is visible light), and the medical light may include invisible light (for example, light with a wavelength of 0 nanometers to 400 nanometers, or light with a wavelength of 800 nanometers to 1000 nanometers is invisible light).

[0066] The detection module 120 can be used to detect the phototherapy avoidance area. The phototherapy avoidance area includes an area that cannot be irradiated by medical light. Exemplarily, the phototherapy avoidance area may include the human eye area, the wound area, and the non-human area (for example, the non-human area may include jewelry, glasses, and clothing, etc.). Correspondingly, the area outside the phototherapy avoidance area may include the facial skin, the neck skin, and the hand skin, etc.

[0067] The phototherapy avoidance area may change. Therefore, the detection module 120 can detect and track the phototherapy avoidance area in real time, and the detection module 120 can also detect the phototherapy avoidance area at regular intervals. For example, the detection module 120 can detect the phototherapy avoidance area every ten seconds.

[0068] The control module 130 can be connected to the detection module 120, the display light module 111, and the phototherapy light module 112. After obtaining the phototherapy avoidance area, the control module 130 can control the phototherapy light module 112 to emit medical light to the area outside the phototherapy avoidance area, and can also control the display light module 111 to emit display light. It can be understood that in one possible example, the control module 130 can control the phototherapy light module 112 and the display light module 111 at the same time. In another possible example, the control module 130 can control either the phototherapy light module 112 or the display light module 111 to work, and the other to stop.

[0069] In this embodiment, firstly, by setting the detection module 120 to detect the phototherapy avoidance area, the control module 130 can control the phototherapy light-emitting module 112 to emit medical light to the area outside the phototherapy avoidance area. At this time, the medical light will not irradiate the phototherapy avoidance area (for example, the human eye area, etc.), and the user does not need to wear an additional shade during phototherapy, thereby reducing the cost of phototherapy beauty. Secondly, the control module 130 can also control the display light-emitting module 111 to emit display light, so that the display module 100 can perform both luminous display and phototherapy beauty, thereby increasing the function of the display module 100. This allows users to watch images while performing phototherapy beauty, thereby improving the utilization rate of the display module 100 and increasing the user experience.

[0070] In one embodiment, the detection module 120 is also used to detect abnormal skin areas.

[0071] The detection module 120 can detect the skin abnormality area while detecting the phototherapy avoidance area. Exemplarily, the skin abnormality area may include a skin area with acne, pimples, fine lines, and sagging. Further, the detection module 120 can also determine the skin abnormality type of the skin abnormality area. The skin abnormality type may include acne, pimples, fine lines, and sagging.

[0072] The detection module 120 may include a camera unit 121 and a processing unit 122. The camera unit 121 is used to obtain a light therapy target image. For example, the camera unit 121 may include a camera 1210, and the camera 1210 may be located at the upper frame of the display device. Figure 2 and Figure 3 , the camera 1210 may be located in the mobile phone ( Figure 2 shown), tablets, laptops ( Figure 3 In this case, the distance between the beauty camera 1210 and the skin can be between 30 cm and 50 cm.

[0073] The phototherapy target image may include an image corresponding to a part of the human body that needs phototherapy. The processing unit 122 is connected to the camera unit 121, and the processing unit 122 is used to process the phototherapy target image to detect phototherapy avoidance areas, skin abnormality areas, and skin abnormality types. Exemplarily, the processing unit 122 can more accurately determine the phototherapy avoidance areas, skin abnormality areas, and skin abnormality types through algorithms such as machine learning. In addition, the phototherapy target image may also include environmental background (such as walls, etc.). The processing unit 122 can distinguish the environmental background, etc. in the phototherapy target image through algorithms such as machine learning.

[0074] The control module 130 is used to control the phototherapy light module 112 to emit medical light to the abnormal skin area.

[0075] After determining the skin abnormality area and the skin abnormality type, the control module 130 can control the light therapy light module 112 to emit medical light to the skin abnormality area to perform accurate medical beauty treatment on the skin abnormality area. Figure 4 When the skin A is an abnormal skin area, the A' of the display area 10 of the display device is the area where the light therapy light module 112 emits medical light. Figure 5 When the skin B is an abnormal skin area, the B' area of ​​the display area 10 of the display device is the area where the phototherapy light-emitting module 112 emits medical light.

[0076] The light therapy light module 112 includes infrared photon pixels and ultraviolet photon pixels. Figure 6, infrared photon pixels can emit infrared light (for example, light with a wavelength between 0.76 micrometers and 1000 micrometers is infrared light), and ultraviolet photon pixels can emit ultraviolet light (for example, light with a wavelength between 10 nanometers and 400 nanometers is ultraviolet light).

[0077] The control module 130 can be used to control infrared photon pixels or ultraviolet photon pixels to emit medical light to abnormal skin areas according to the type of skin abnormality. For example, infrared light can be used for skin abnormalities such as fine lines and sagging, and ultraviolet light can be used for skin abnormalities such as acne and acne. Exemplarily, infrared light has deep penetration ability, can penetrate deep into the skin, promote blood circulation, enhance metabolism, and help the skin maintain a healthy state. In addition, infrared rays can also stimulate the production of collagen, which helps to improve skin sagging and wrinkles. Ultraviolet light can help the skin synthesize vitamin D and promote the absorption and utilization of calcium. Moreover, ultraviolet rays have bactericidal and anti-inflammatory effects, which can reduce bacteria and inflammatory reactions on the skin surface. This is helpful for treating skin problems such as acne and acne.

[0078] Infrared and ultraviolet rays may cause damage to the phototherapy avoidance area (for example, the human eye area, etc.). For example, infrared rays may increase the possibility of radiation cataracts, fundus damage, eclipse retinopathy, etc. in the human eye. Ultraviolet rays may cause corneal damage and lens degeneration, leading to diseases such as cataracts and glaucoma, and may also cause discomfort symptoms such as dry eyes and fatigue. Therefore, the control module 130 controls the medical light emitted by the phototherapy light module 112 not to irradiate the phototherapy avoidance area (for example, the human eye area, etc.).

[0079] In this embodiment, the phototherapy avoidance area, the skin abnormality area, and the skin abnormality type are obtained through the camera unit 121 and the processing unit 122, and the infrared photon pixels or ultraviolet photon pixels are controlled to emit medical light to the skin abnormality area according to the skin abnormality type, thereby improving the efficiency of phototherapy.

[0080] See also Figure 7, the following is an exemplary description of the workflow of the detection module 120 and the control module 130. First, use the camera 1210 to take a photo of the face to obtain a phototherapy target image. Secondly, the phototherapy target image is processed to detect the phototherapy avoidance area, the skin abnormality area, and the skin abnormality type of the skin abnormality area. In this process, the position of the human eye and the like can be tracked continuously. Then, the display light module 111 can work normally, and at the same time, the control module 130 can control the phototherapy light module 112 to emit infrared light or ultraviolet light to the area outside the phototherapy avoidance area according to the skin abnormality type. For example, infrared light can be used for skin abnormality types such as fine lines and sagging, and ultraviolet light can be used for skin abnormality types such as acne and acne. In this process, the camera 1210 can track the phototherapy avoidance area, the skin abnormality area, and the skin abnormality area in real time, and can change the optical path of the medical light emitted by the phototherapy light module 112 in real time. In addition, during the use of the phototherapy function, the skin state can also be detected regularly (for example, every hour), and the phototherapy effect and subsequent phototherapy time can be judged based on the detection results. During the use of non-phototherapy functions (for example, only display functions), the camera 1210 can also be used to take pictures of the face and detect the skin condition regularly (for example, every other day), which is conducive to timely detection of skin abnormalities and phototherapy.

[0081] In this embodiment, the detection module 120 is set to detect the phototherapy avoidance area, the skin abnormality area, and the skin abnormality type in real time, so as not only to protect the phototherapy avoidance area but also to perform targeted phototherapy on the skin condition.

[0082] In one embodiment, please read Figures 8 to 11 , the pixel layer 110 includes a light-emitting layer 113 and a filter layer 114 .

[0083] The light emitting layer 113 is used to emit light and may include a plurality of light emitting units arranged at intervals.

[0084] The filter layer 114 is used to filter out the color of light. The filter layer 114 is located on one side of the light-emitting layer 113, and the filter layer 114 may include a display pixel color resist 1140 and a phototherapy pixel color resist 1141 arranged opposite to the light-emitting unit. Each light-emitting unit has a corresponding display pixel color resist 1140 or a phototherapy pixel color resist 1141. It can be understood that the light emitted through the display pixel color resist 1140 is the display light, and the light emitted through the phototherapy pixel color resist 1141 is the medical light. At this time, the display light-emitting module 111 and the phototherapy light-emitting module 112 can be arranged in the same layer.

[0085] Exemplarily, the light-emitting layer 113 is a white light layer that emits white light. The white light layer may include an OLED layer 1130 and a pixel definition unit 1131, and the film layer between adjacent pixel definition units 1131 is the OLED layer 1130. In addition to the display pixel color resist 1140 and the phototherapy pixel color resist 1141, the filter layer 114 may also include a plurality of black matrices 1142 (BlackMatrix) arranged at intervals. Between adjacent black matrices 1142 are display pixel color resists 1140 or phototherapy pixel color resists 1141. The black matrix 1142 and the pixel definition unit 1131 may be arranged correspondingly. The display pixel color resist 1140 includes a three-primary color filter, and the phototherapy pixel color resist 1141 includes a medical light filter. Among them, the three-primary color filter includes a color filter having three basic colors of red, green and blue, and the medical light filter includes an infrared filter 11410 and an ultraviolet filter 11411. The infrared filter 11410 includes an infrared color blocking material, and the white light emitted by the white light layer can be converted into infrared light at room temperature through the infrared filter 11410. Similarly, the ultraviolet filter 11411 includes an ultraviolet color blocking material, and the white light emitted by the white light layer can be converted into ultraviolet light at room temperature through the ultraviolet filter 11411.

[0086] In addition, the display module 100 may further include a pixel driving layer 140 (Thin Film Transistor, TFT) and an encapsulation layer 150. The pixel driving layer 140 is located on the side of the light emitting layer 113 away from the filter layer 114, and the pixel driving layer 140 is used to drive the light emitting layer 113 to emit light. It can be understood that if no skin abnormality is detected, the pixel driving layer 140 can control the light emitting unit corresponding to the phototherapy pixel color resistor 1141 not to emit light, and if skin abnormality is detected, the pixel driving layer 140 can control the light emitting unit corresponding to the phototherapy pixel color resistor 1141 to emit light. The encapsulation layer 150 is located between the light emitting layer 113 and the filter layer 114, and the encapsulation layer 150 is used to protect the light emitting layer 113 and prevent water, oxygen, etc. from entering the protective light emitting layer 113. The encapsulation layer 150 can also reduce the stress between the light emitting layer 113 and the filter layer 114. The encapsulation layer 150 can have a flat upper surface, which is conducive to the preparation of the encapsulation layer 150.

[0087] Of course, the display module 100 may further include structures such as a cover plate 160 . The cover plate 160 covers the light control layer 170 to protect the display module 100 from damages such as external impacts and scratches.

[0088] In this embodiment, firstly, the brightness of the display module 100 is improved by setting the light-emitting layer 113 and the display pixel color resist 1140. Secondly, the light-emitting layer 113 is set to emit white light, and the display light and the medical light are obtained through the display pixel color resist 1140 and the phototherapy pixel color resist 1141, so that the display light-emitting module 111 and the phototherapy light-emitting module 112 can be prepared in the same layer, which reduces the difficulty of preparing the display light-emitting module 111 and the phototherapy light-emitting module 112.

[0089] In one embodiment, the display light emitting module 111 includes a plurality of display sub-pixels 1110 , and the light therapy light emitting module 112 includes a plurality of light therapy sub-pixels 1120 .

[0090] Exemplarily, the pixel layer 110 includes a plurality of rows of sub-pixels arranged periodically, and each period includes at least two rows of display sub-pixels 1110 and a row of phototherapy sub-pixels 1120. Each row of display sub-pixels 1110 includes red display sub-pixels, green display sub-pixels, and blue display sub-pixels arranged in sequence. Each row of phototherapy sub-pixels 1120 includes infrared light sub-pixels and ultraviolet light sub-pixels arranged alternately. The row of phototherapy sub-pixels 1120 can be located on one side of the two rows of display sub-pixels 1110, or in the middle of the two rows of display sub-pixels 1110.

[0091] For further information, see Fig. 9 , the pixel layer 110 includes a light-emitting layer 113 and a filter layer 114, the filter layer 114 includes multiple rows of color resists arranged periodically, and each period includes at least two rows of display pixel color resists 1140 and a row of phototherapy pixel color resists 1141. The display pixel color resists 1140 include display pixel filters. Each row of display pixel color resists 1140 includes a red pixel filter 11400, a green pixel filter 11401, and a blue pixel filter 11402 arranged in sequence. Each row of phototherapy pixel color resists 1141 includes an infrared filter 11410 and an ultraviolet filter 11411 arranged alternately. The row of phototherapy pixel color resists 1141 can be located on one side of the two rows of display pixel color resists 1140, or in the middle of the two rows of display pixel color resists 1140.

[0092] In this embodiment, each cycle is set to include at least two rows of display sub-pixels 1110 and one row of light therapy sub-pixels 1120 to ensure the display effect of the display light emitting module 111. In this embodiment, the display light emitting module 111 and the light therapy light emitting module 112 can also be cross-set, so as to facilitate the integrated formation of the display module 100 and improve the display range and aesthetics of the display module 100.

[0093] In another embodiment, the display light-emitting module 111 and the phototherapy light-emitting module 112 can be independently provided. The display light-emitting module 111 can include a light-emitting diode capable of emitting display light, and the phototherapy light-emitting module 112 can include a film layer capable of directly emitting medical light. In this case, the display light-emitting module 111 and the phototherapy light-emitting module 112 can be prepared independently. In another embodiment, one area of ​​the display module 100 can be set as the display light-emitting module 111, and another area can be set as the phototherapy light-emitting module 112, thereby reducing the difficulty of preparing the display module 100.

[0094] In one embodiment, the display module 100 further includes a light control layer 170 .

[0095] The light control layer 170 can be used to control the light path of the light emitted by the light emitting layer 113. The light control layer 170 can be located on one side of the pixel layer 110. Specifically, the light control layer 170 can be located on the side of the filter layer 114 away from the light emitting layer 113.

[0096] The light control layer 170 may include a plurality of convex cavity structures 171 and partition structures 172. The convex cavity structures 171 are located between adjacent partition structures 172. The convex cavity structures 171 protrude along the thickness direction of the display module 100. The light emitted by the light emitting layer 113 may be refracted at the convex cavity structures 171, so that the convex cavity structures 171 may control the direction of light emitted by the display light emitting module 111 and the light therapy light emitting module 112.

[0097] The convex cavity structure 171 may include a fixed convex cavity structure 1711 and a variable convex cavity structure 1712. The fixed convex cavity structure 1711 is arranged opposite to the display light-emitting module 111, and the variable convex cavity structure 1712 is arranged opposite to the phototherapy light-emitting module 112, so that the light emitted by the phototherapy light-emitting module 112 can avoid the phototherapy avoidance area more accurately, and at the same time, the light emitted by the phototherapy light-emitting module 112 can be more concentrated on the skin abnormality area.

[0098] In one possible example, see Fig.10 and Fig.11 , the variable convex cavity structure 1712 may include transparent charged particles 17121 and a control electrode 17122. Under the control of the control electrode 17122, the distribution of the transparent charged particles 17121 in the variable convex cavity structure 1712 may be changed.

[0099] The transparent charged particles 17121 may include first charged particles 17121A and second charged particles 17121B. For example, the first charged particles 17121A may be positively charged, and the second charged particles 17121B may be negatively charged. The first charged particles 17121A and the second charged particles 17121B have different refractive indices. For example, the first charged particles 17121A may have a specified refractive index, and the second charged particles 17121B may have no refractive index. For another example, the first charged particles 17121A may have a first refractive index, and the second charged particles 17121B may have a second refractive index.

[0100] The control electrode 17122 may surround the transparent charged particles 17121. At this time, the control electrode 17122 may include a first electrode 17122A and a second electrode 17122B, wherein the first electrode 17122A is located at both ends of the variable convex cavity structure 1712 in the first direction, and the second electrode 17122B is located at both ends of the variable convex cavity structure 1712 in the second direction. For example, the first direction is the direction of gravity, the second direction is a direction parallel to the display module 100, and the first direction intersects with the second direction. The material of the first electrode 17122A includes a reflective material, which has a total reflection property and can reflect light. The material of the second electrode 17122B includes a transparent material, so that light is emitted.

[0101] Of course, the control electrode 17122 may also be located inside the transparent charged particles 17121. For example, the control electrode 17122 may extend along the gravity direction, and the transparent charged particles 17121 may surround the control electrode 17122.

[0102] In this embodiment, after the detection module 120 detects the type of skin abnormality, the control module 130 can control the working voltage of the control electrode 17122 according to the type of skin abnormality (the working voltage may include the polarity of the control electrode 17122 and the voltage intensity of the control electrode 17122), thereby changing the distribution of the transparent charged particles 17121, and then changing the optical path of the light emitted by the phototherapy light-emitting module 112, so that the light emitted by the phototherapy light-emitting module 112 can more accurately avoid the phototherapy avoidance area. At the same time, the light emitted by the phototherapy light-emitting module 112 can also be more concentrated on the skin abnormality area, thereby improving the phototherapy effect.

[0103] In another possible example, the variable convex cavity structure 1712 may include magnetic particles and variable magnetic poles, etc. In this case, the distribution of the magnetic particles may be changed by changing the variable magnetic poles, thereby changing the optical path of the light emitted by the light therapy light emitting module 112.

[0104] Based on the same inventive concept, in one embodiment, please refer to Fig.12, a control method of a display module is provided. The display module 100 may include a pixel layer 110, and the pixel layer 110 includes a display light emitting module 111 and a phototherapy light emitting module 112. Among them, the module capable of emitting display light is the display light emitting module 111, and the module capable of emitting medical light is the phototherapy light emitting module 112. The control method of the display module 100 includes:

[0105] Step S2: Detecting the phototherapy avoidance area.

[0106] Step S4: Control the phototherapy light-emitting module 112 to emit therapeutic light to areas outside the phototherapy avoidance area.

[0107] Step S6: Control the display light emitting module 111 to emit light for display.

[0108] In step S2, the phototherapy avoidance area includes an area that cannot be irradiated by medical light. For example, the phototherapy avoidance area may include a human eye area, a wound area, and a non-human area.

[0109] In step S4 and step S6 , the display module 100 may further include a pixel driving layer 140 , and the pixel driving layer 140 may drive the light therapy light module 112 and the display light module 111 to emit light.

[0110] Areas outside the phototherapy avoidance zone may include the skin on the face, neck, and hands, etc.

[0111] In one example, the light therapy light module 112 can be controlled to emit medical light to an area outside the light therapy avoidance area while the display light module 111 can be controlled to emit light. In another example, the light therapy light module 112 can be controlled to work and the display light module 111 can be controlled to stop, or the display light module 111 can be controlled to work and the light therapy light module 112 can be controlled to stop.

[0112] In this embodiment, by determining the phototherapy avoidance area, the phototherapy light emitting module 112 is controlled to emit medical light to the area outside the phototherapy avoidance area, so that the medical light will not irradiate the phototherapy avoidance area, and the user does not need to wear an additional light-shielding eye mask during phototherapy, thereby reducing the cost of phototherapy beauty. Moreover, this embodiment can also control the display light emitting module 111 to emit display light, so that the display module 100 can perform both light display and phototherapy beauty, thereby increasing the function of the display module 100. Furthermore, this embodiment can control the display light emitting module 111 to emit display light while controlling the phototherapy light emitting module 112 to emit medical light to the area outside the phototherapy avoidance area. This allows users to watch images while performing phototherapy beauty, thereby improving the utilization rate of the display module 100 and enhancing the user experience.

[0113] In one embodiment, step S2 includes:

[0114] Step S20: Acquire a phototherapy target image.

[0115] Step S22: Processing the phototherapy target image to detect the phototherapy avoidance area.

[0116] In step S20 to step S22, a phototherapy target image may be acquired through the camera 1210, etc. The phototherapy target image may include an image corresponding to the skin that needs phototherapy.

[0117] Exemplarily, the method for processing the phototherapy target image may include performing grayscale processing, sharpening, and other image processing processes on the phototherapy target image to obtain a phototherapy target image with higher definition. Then, a phototherapy avoidance area (e.g., the position of a part such as a human eye) is determined in the phototherapy target image with higher definition. This process may use algorithms such as machine learning to obtain an accurate phototherapy avoidance area.

[0118] In this embodiment, the phototherapy target image is processed to accurately obtain the phototherapy avoidance area. In addition, this embodiment can also obtain the phototherapy target image in real time to track the phototherapy avoidance area.

[0119] In one embodiment, step S22 also includes:

[0120] Step S220: Detect abnormal skin areas.

[0121] Accordingly, step S4 includes:

[0122] Step S40: Control the phototherapy light-emitting module 112 to emit therapeutic light to the abnormal skin area.

[0123] In step S220, illustratively, the skin abnormality area may include a skin area with pimples, acne, fine lines, sagging, etc. Further, the detection module 120 may also determine the skin abnormality type of the skin abnormality area.

[0124] Of course, while detecting skin abnormality areas, skin abnormality types can also be detected. Skin abnormality types can include acne, pimples, fine lines, and sagging.

[0125] In step S40, the phototherapy light-emitting module 112 can emit medical light to the abnormal skin area to perform accurate medical beauty treatment on the abnormal skin area.

[0126] The phototherapy light-emitting module 112 includes infrared photon pixels and ultraviolet photon pixels. When the phototherapy light-emitting module 112 emits medical light to the skin abnormal area, it controls the infrared photon pixels or ultraviolet photon pixels to emit medical light to the skin abnormal area according to the skin abnormality type. For example, infrared light can be used for skin abnormalities such as fine lines and sagging, and ultraviolet light can be used for skin abnormalities such as acne and acne.

[0127] In addition, the display module 100 further includes a light control layer 170 located on one side of the pixel layer 110, and the light control layer 170 includes a fixed convex cavity structure 1711 and a variable convex cavity structure 1712. The fixed convex cavity structure 1711 is arranged opposite to the display light-emitting module 111, and the variable convex cavity structure 1712 is arranged opposite to the light therapy light-emitting module 112. The variable convex cavity structure 1712 includes transparent charged particles 17121 and a control electrode 17122. After detecting the type of skin abnormality, it also includes:

[0128] Step S8: Control the operating voltage of the control electrode 17122 according to the type of skin abnormality.

[0129] The working voltage of the control electrode 17122 may include the polarity of the control electrode 17122 and the voltage intensity of the control electrode 17122. By controlling the working voltage of the control electrode 17122, the distribution of the transparent charged particles 17121 is changed, and then the optical path of the light emitted by the phototherapy light-emitting module 112 is changed, so that the light emitted by the phototherapy light-emitting module 112 can avoid the phototherapy avoidance area more accurately, and at the same time, the light emitted by the phototherapy light-emitting module 112 can be more concentrated on the abnormal skin area, thereby improving the phototherapy effect.
