Description

Technical Field

[0001] This application relates to the field of display technologies, and particularly to a display screen and a display device. Background Art

[0002] With the rapid development of display technologies, display products, which can display rich and colorful information, have been increasingly applied in various fields. Currently, display devices with a specular reflection function usually adopt liquid crystal displays, and mainly rely on polarizers to achieve the specular reflection function.

[0003] However, the reflectivity of the polarizer is low, resulting in a poor specular reflection effect; moreover, the display brightness of the liquid crystal display is low, resulting in a poor display effect. Summary of the Invention

[0004] Embodiments of this application provide a display screen and a display device, which are used to at least solve the problem of low display brightness of display devices with a specular display function in related technologies.

[0005] On the one hand, embodiments of this application provide a display screen, which includes an array substrate, a plurality of micro light-emitting diodes, a plurality of lenses, and a specular reflection layer. The micro light-emitting diodes are disposed on the array substrate, and the plurality of lenses are disposed on a side of the plurality of micro light-emitting diodes away from the array substrate; the specular reflection layer is disposed on a side of the plurality of lenses away from the array substrate. Among them, the specular reflection layer has a plurality of openings for emitting at least part of the light emitted by the micro light-emitting diodes.

[0006] In some embodiments, the display screen further includes a first encapsulation layer disposed on the array substrate for encapsulating the plurality of micro light-emitting diodes. The thickness of the first encapsulation layer is not greater than the height of the micro light-emitting diodes, and the reflectivity of the first encapsulation layer to visible light is greater than or equal to 70%.

[0007] In some embodiments, the thickness of the first encapsulation layer is equal to the height of the micro light-emitting diodes.

[0008] In some embodiments, the display screen further includes a second encapsulation layer disposed on the first encapsulation layer. The second encapsulation layer covers the plurality of micro light-emitting diodes, and the plurality of lenses are disposed on the second encapsulation layer.

[0009] In some embodiments, the plurality of micro light-emitting diodes and the plurality of lenses are in one-to-one correspondence, and each micro light-emitting diode is located at the focal point of the corresponding lens.

[0010] In some embodiments, the display screen further includes a cover plate, the cover plate is disposed on a side of the plurality of lenses away from the array substrate, and is bonded to the second encapsulation layer, and the specular reflection layer is disposed on the cover plate.

[0011] In some embodiments, each of the openings is correspondingly disposed with one of the light-emitting diodes, and at least partially exposes the corresponding micro-light-emitting diode. Along the thickness direction of the display screen, the geometric center of the opening coincides with the geometric center of the corresponding micro-light-emitting diode.

[0012] In some embodiments, the opening completely exposes the corresponding micro-light-emitting diode, and the ratio of the orthographic projection area of the opening on the array substrate to the orthographic projection area of the corresponding micro-light-emitting diode on the array substrate is greater than or equal to 1 and less than or equal to 1.5.

[0013] In some embodiments, the array substrate includes a substrate and a driving circuit layer located on the substrate, and the plurality of micro-light-emitting diodes are electrically connected to the driving circuit layer.

[0014] In some embodiments, the specular reflection layer includes a first metal layer and a second metal layer that are sequentially stacked in a direction away from the array substrate. The first metal layer is a silver layer, and the second metal layer is an aluminum layer.

[0015] On the other hand, an embodiment of the present application further provides a display device, and the display device includes the display screen as described in any one of the above embodiments.

[0016] For the display screen provided by the embodiment of the present application, since the micro-light-emitting diode has a high luminous efficiency and can emit strong light with less energy consumption, after the micro-light-emitting diode is adopted, the display brightness of the display screen can be effectively improved. The micro-light-emitting diode has a high color purity, can present bright and vivid colors, and can improve the contrast of the display screen. Moreover, the micro-light-emitting diode has a small size, so that the pixel density in the display screen can be increased, thereby improving the resolution of the display screen. In addition, since the lens modulates the light output of the micro-light-emitting diode, the display brightness of the display screen can be further improved. On the other hand, since the micro-light-emitting diode has a small size, the size of the opening can be effectively reduced, thereby increasing the reflection area of the main body of the specular reflection layer, and further improving the specular reflection effect of the display screen. And, since the lens modulates the light output of the micro-light-emitting diode, the light emitted by the micro-light-emitting diode is converged and emitted within a smaller range, so that the size of the opening can be further reduced to further increase the reflection area of the main body of the specular reflection layer to improve the specular reflection effect of the display screen.

[0037] The use of "suitable for" or "configured to" in the present application means open and inclusive language, which does not exclude devices suitable for or configured to perform additional tasks or steps. In addition, the use of "based on" means open and inclusive, because a process, step, calculation or other action "based on" one or more of the stated conditions or values can in practice be based on additional conditions or values beyond the stated ones.

[0038] The various embodiments of the present application are similar, and the features in different embodiments and / or different examples can be combined with each other.

[0039] Some embodiments of the present application provide a display screen, such as Figures 1 to 3 and Figure 6 As shown, the display screen 100 includes: an array substrate 10, a light-emitting device layer 20, a lens layer 30, and a specular reflection layer 40.

[0040] The light-emitting device layer 20 includes a plurality of micro light-emitting diodes 21 disposed on the array substrate 10. The micro light-emitting diodes 21 can be Micro LEDs (Light-Emitting Diodes) or Mini LEDs. When the micro light-emitting diodes 21 are Mini LEDs, the size of the micro light-emitting diodes 21 is greater than 100 μm and less than or equal to 300 μm. When the micro light-emitting diodes 21 are Micro LEDs, the size of the micro light-emitting diodes 21 is greater than or equal to 1 μm and less than or equal to 100 μm. In this embodiment, the micro light-emitting diodes 21 are selected as Micro LEDs. For example, the size of the Micro LEDs can be set in the range of 10 μm to 50 μm.

[0041] The lens layer 30 includes a plurality of lenses 31 disposed on the side of the light-emitting device layer 20 away from the array substrate 10. Each lens 31 can modulate the light emitted from the corresponding micro light-emitting diode 21, so that this part of the light is gathered and emitted at a smaller angle, thereby improving the display brightness of the display screen 100. Among them, each lens 31 can correspond to one or more micro light-emitting diodes 21.

[0042] The specular reflection layer 40 is disposed on the side of the lens layer 30 away from the array substrate 10. The specular reflection layer 40 has a plurality of openings 401 for emitting at least part of the light emitted by the micro light-emitting diodes 21.

[0043] For the display screen 100 provided by the embodiments of the present application, when the micro light-emitting diodes 21 are turned on, the light emitted by the micro light-emitting diodes 21 can be modulated by the corresponding lenses 31 and then emitted through the openings 401, thereby realizing the display function of the display screen 100. In addition, the main body of the specular reflection layer 40 outside the openings 401 can effectively reflect natural light, thereby realizing the specular reflection function of the display screen 100, so that the user can use the display screen 100 as a mirror. As an example, the display screen 100 can be used as a mirror when the micro light-emitting diodes 21 are turned off to avoid interference from the display screen of the display screen 100.

[0044] On the one hand, since the micro light-emitting diode 21 has a high luminous efficiency and can emit strong light with less energy consumption, after the micro light-emitting diode 21 is adopted, the display brightness of the display screen 100 can be effectively improved. The micro light-emitting diode 21 has a high color purity, can present bright and vivid colors, and can improve the contrast of the display screen 100. Moreover, the micro light-emitting diode 21 has a small size, so that the pixel density in the display screen 100 can be increased, thereby improving the resolution of the display screen 100. In addition, since the lens 31 modulates the light emitted by the micro light-emitting diode 21, the display brightness of the display screen 100 can be further improved.

[0045] On the other hand, since the micro light-emitting diode 21 has a small size, the size of the opening 401 can be effectively reduced, thereby increasing the reflection area of the main body of the mirror reflection layer 40, and further improving the mirror reflection effect of the display screen 100. Moreover, since the lens 31 modulates the light emitted by the micro light-emitting diode 21, the light emitted by the micro light-emitting diode 21 is converged and emitted in a smaller range, so that the size of the opening 401 can be further reduced to further increase the reflection area of the main body of the mirror reflection layer 40 to improve the mirror reflection effect of the display screen 100.

[0046] It should be noted that for a display with a mirror reflection function, due to its usage scenario limitations, the ambient light usually has a relatively high intensity. And if the display function needs to be used under relatively high-intensity ambient light, the display needs to be adjusted to a relatively high brightness to reduce the interference brought by the ambient light when the user views the display screen. For the display screen 100 provided by the embodiments of the present application, on the one hand, it utilizes the characteristic of the high luminous efficiency of the micro light-emitting diode 21 itself, and on the other hand, combines the convergence of the light emitted by the micro light-emitting diode 21 by the lens 31, so as to achieve high-brightness display of the display screen 100, effectively reducing the interference of high-intensity ambient light on the user when viewing the display screen 100. Moreover, the main body of the mirror reflection layer 40 occupies a relatively large area, thus effectively ensuring that the display screen 100 can be used as a mirror.

[0047] In some embodiments, each opening 401 can be located above a plurality of micro light-emitting diodes 21, so as to emit the light emitted by the plurality of micro light-emitting diodes 21. In this case, the opening 401 has a relatively large size, so that the light output of the display screen 100 can be increased, which is beneficial to improving the display brightness of the display screen 100.

[0048] In some other embodiments, each opening 401 may be located above a micro - light - emitting diode 21 to emit the light emitted by the micro - light - emitting diode 21. As an example, each opening 401 may expose at least a part of the corresponding micro - light - emitting diode 21. For example, each opening 401 may expose a part (such as half of the micro - light - emitting diode 21) of the corresponding micro - light - emitting diode 21; or, each opening 401 may expose all of the corresponding micro - light - emitting diode 21.

[0049] When each opening 401 is located above a corresponding micro - light - emitting diode 21, the size of the opening 401 can be effectively reduced, so that the reflection area of the main body of the mirror reflection layer 40 is increased, thereby improving the mirror reflection effect of the display screen 100.

[0050] In some examples, multiple lenses 31 may correspond to multiple micro - light - emitting diodes 21 one by one. As an example, multiple micro - light - emitting diodes 21 may be arranged in an array. Correspondingly, multiple lenses 31 and multiple openings 401 are also arranged in an array respectively, so that a lens 31 and an opening 401 are sequentially provided above each micro - light - emitting diode 21, thereby ensuring that the light emitted by the micro - light - emitting diode 21 can be effectively emitted.

[0051] In some examples, multiple micro - light - emitting diodes 21 for emitting different - colored lights may form a light - emitting unit, and multiple light - emitting units are arranged in an array on the array substrate 10. Among them, each light - emitting unit may include, for example, multiple micro - light - emitting diodes 21 that respectively emit red light, green light, and blue light. In this way, the display screen 100 can display a color picture.

[0052] In some embodiments, as Figure 2 and Figure 3 shown, the display screen 100 further includes a first encapsulation layer 51 located on the array substrate 10 to encapsulate all micro - light - emitting diodes 21. The thickness of the first encapsulation layer 51 is not greater than the height of the micro - light - emitting diode 21, and the reflectivity of the first encapsulation layer 51 to visible light is greater than or equal to 70%.

[0053] With such a setting, on the one hand, the first encapsulation layer 51 can encapsulate the micro - light - emitting diode 21 to improve the stability and service life of the micro - light - emitting diode 21; on the other hand, it can also reflect the light laterally emitted by the micro - light - emitting diode 21 to forward emission, thereby significantly improving the light - emitting effect of the micro - light - emitting diode 21. In addition, when a part of the structure of the first encapsulation layer 51 is exposed by the opening 401, the first encapsulation layer 51 can also reflect ambient light, thereby improving the mirror reflection effect of the display screen 100.

[0054] As an example, the first encapsulation layer 51 includes a main material layer and a microsphere structure located within the main material layer. By controlling the particle size and arrangement of the microsphere structure, the reflectivity of the first encapsulation layer 51 to visible light can be adjusted. The material of the main material layer can be an organic material, such as polystyrene or polyimide, etc. Exemplarily, the microsphere structure can be nanoparticles, and the material of the microsphere structure can be selected as titanium dioxide.

[0055] In some examples, as Figure 2 shown, the thickness D1 of the first encapsulation layer 51 is less than the height D2 of the micro light-emitting diode 21. For example, the thickness D1 of the first encapsulation layer 51 can be greater than or equal to 1 / 2 of the height D2 of the micro light-emitting diode 21 and less than the height D2 of the micro light-emitting diode 21. Exemplarily, the thickness D1 of the first encapsulation layer 51 can be equal to 2 / 3, 3 / 4, or 4 / 5, etc. of the height D2 of the micro light-emitting diode 21.

[0056] In other examples, as Figure 3 shown, the thickness D1 of the first encapsulation layer 51 is equal to the height D2 of the micro light-emitting diode 21. In this case, the surface of the first encapsulation layer 51 on the side away from the array substrate 10 is flush with the surface of the micro light-emitting diode 21 on the side away from the array substrate 10. Therefore, the light emitted from the side of the micro light-emitting diode 21 can be reflected by the first encapsulation layer 51 as much as possible and exit from the front of the micro light-emitting diode 21, so that the front light extraction efficiency of the micro light-emitting diode 21 can be improved. And, through the reflection of the first encapsulation layer 51, the light emitted from the side of the micro light-emitting diode 21 entering the light extraction position of the adjacent micro light-emitting diode 21 can also be effectively reduced, thereby avoiding the problem of light crosstalk between adjacent multiple micro light-emitting diodes 21. In addition, the top planes of the first encapsulation layer 51 and the micro light-emitting diode 21 can form a continuous surface, so that the lens layer 30 can be directly arranged on this continuous surface, which is beneficial to reducing the thickness of the display screen 100.

[0057] In some embodiments, please continue to refer to Figure 2 and Figure 3 , the display screen 100 further includes a second encapsulation layer 52 located on the first encapsulation layer 51. The second encapsulation layer 52 covers multiple micro light-emitting diodes 21, and multiple lenses 31 are disposed on the second encapsulation layer 52. Among them, the second encapsulation layer 52 is made of a transparent material to ensure that the light emitted by the micro light-emitting diodes 21 can be smoothly extracted.

[0058] By providing the second encapsulation layer 52, the top of the micro light-emitting diode 21 can be encapsulated and protected, avoiding risks such as the micro light-emitting diode 21 being vulnerable to water and oxygen erosion. In addition, the second encapsulation layer 52 can also form a planarized surface, which is beneficial for the fabrication of the lens 31. On the other hand, the thickness of the second encapsulation layer 52 can be adjusted as needed. In this way, the distance between the micro light-emitting diode 21 and the corresponding lens 31 can be adjusted, so that the micro light-emitting diode 21 achieves a better light-emitting effect.

[0059] In some embodiments, as Figure 4 shown, each micro light-emitting diode 21 is located at the focal point F of the corresponding lens 31. Such an arrangement can make the light emitted by the micro light-emitting diode 21 form parallel light after passing through the corresponding lens 31, so that the light can smoothly exit through the corresponding opening 401, thereby improving the light-emitting efficiency of the micro light-emitting diode 21. Moreover, the lens 31 also makes the light converging effect better and the light intensity distribution more uniform, thereby improving the display effect of the display screen 100.

[0060] It should be noted that since the second encapsulation layer 52 is provided on the first encapsulation layer 51 and the thickness of the second encapsulation layer 52 is adjustable, it can be ensured that each micro light-emitting diode 21 is located at the focal point F of the corresponding lens 31.

[0061] As an example, the geometric center O2 of each micro light-emitting diode 21 coincides with the focal point F of the corresponding lens 31. This can further improve the light-emitting efficiency of the micro light-emitting diode 21 and the display effect of the display screen 100.

[0062] In some embodiments, as Figures 1 to 3 and Figure 6 shown, each opening 401 is correspondingly arranged with a micro light-emitting diode 21 and at least partially exposes the corresponding micro light-emitting diode 21. For example, each opening 401 can expose a part of the structure of the corresponding micro light-emitting diode 21; or each opening 401 can completely expose the corresponding micro light-emitting diode 21.

[0063] In this embodiment, each opening 401 completely exposes the corresponding micro light-emitting diode 21, which can improve the light extraction efficiency of the opening 401 for the micro light-emitting diode 21.

[0064] In some examples, as Figure 4 shown, along the thickness direction of the display screen 100, the geometric center O1 of the opening 401 coincides with the geometric center O2 of the corresponding micro light-emitting diode 21. That is to say, the extension direction of the line connecting the geometric center O1 of the opening 401 and the geometric center O2 of the corresponding micro light-emitting diode 21 is parallel to the thickness direction of the display screen 100.

[0065] In this case, the light emitted by the micro light-emitting diode 21 forms a light beam through the convergence of the corresponding lens 31. In this light beam, the center of the spot with the maximum intensity coincides with the geometric center O1 of the opening 401, so that the light emitted by the micro light-emitting diode 21 can be effectively emitted from the corresponding lens 31, thereby improving the light extraction efficiency of the micro light-emitting diode 21.

[0066] In some embodiments, each opening 401 completely exposes the corresponding micro light-emitting diode 21, and the ratio of the orthographic projection area of the opening 401 on the array substrate 10 to the orthographic projection area of the corresponding micro light-emitting diode 21 on the array substrate 10 is greater than or equal to 1 and less than or equal to 1.5.

[0067] By setting the ratio of the orthographic projection area of the opening 401 on the array substrate 10 to the orthographic projection area of the corresponding micro light-emitting diode 21 on the array substrate 10 within the range of 1 to 1.5, it is possible to effectively avoid the problem that the light extraction efficiency of the micro light-emitting diode 21 decreases due to the too small area of the opening 401, resulting in a poor display effect of the display screen 100; at the same time, it can also avoid the problem that the area of the main part of the specular reflection layer 40 becomes relatively small due to the too large area of the opening 401, resulting in a poor specular reflection effect of the display screen 100.

[0068] In some embodiments, the shape of the orthographic projection of the opening 401 on the array substrate 10 may be the same as the shape of the orthographic projection of the micro light-emitting diode 21 on the array substrate 10. In this way, the amount of light emitted by the micro light-emitting diode 21 exiting from the corresponding opening 401 can be further increased, thereby improving the light extraction efficiency of the micro light-emitting diode 21 and enhancing the display brightness of the display screen 100.

[0069] In some other embodiments, the shape of the orthographic projection of the opening 401 on the array substrate 10 may be different from the shape of the orthographic projection of the micro light-emitting diode 21 on the array substrate 10. In this case, the opening 401 may expose a part of the structure of the first encapsulation layer 51. At this time, the first encapsulation layer 51 can also reflect the ambient light, thereby further improving the specular reflection effect of the display screen 100.

[0070] In some examples, the ratio of the orthographic projection area of the opening 401 on the array substrate 10 to the orthographic projection area of the corresponding micro light-emitting diode 21 on the array substrate 10 is greater than 1 and less than or equal to 1.5. In this case, the opening 401 may expose a part of the structure of the first encapsulation layer 51. At this time, the first encapsulation layer 51 can also reflect the ambient light, thereby further improving the specular reflection effect of the display screen 100.

[0071] For example, the ratio of the orthographic projection area of the opening 401 on the array substrate 10 to the orthographic projection area of the corresponding micro light-emitting diode 21 on the array substrate 10 can be 1.1, 1.2, 1.3, 1.4, 1.5, etc.

[0072] In some embodiments, as Figure 5 shown, any two adjacent openings 401 are arranged at intervals. By spacing the adjacent openings 401 from each other, the problem of crosstalk of the light emitted by two adjacent micro light-emitting diodes 21 at the position of the corresponding opening 401 can be effectively avoided, thereby improving the display effect of the display screen 100.

[0073] It should be noted that Figure 5 the circular opening 401 is used as an example for illustration. The opening 401 can also be rectangular, rounded rectangular or regular polygonal, etc., and the embodiments of the present application do not limit this.

[0074] In some embodiments, the specular reflection layer 40 can be made of a metal material. The metal material can be, for example, at least one of aluminum and silver. These materials have a high reflectivity, so as to achieve a good specular reflection effect. In addition, the specular reflection layer 40 can be obtained after patterning a metal layer formed by a metal material.

[0075] In some embodiments, as Figure 6 shown, the specular reflection layer 40 includes a first metal layer 41 and a second metal layer 42 that are sequentially stacked in a direction away from the array substrate 10. The first metal layer 41 is a silver layer, and the second metal layer 42 is an aluminum layer.

[0076] The reflectivity of aluminum to visible light is compared with that of silver to visible light, and both are usually less than 98%. In the embodiments of the present application, the aluminum layer and the silver layer are usually stacked, so that the reflectivity of the specular reflection layer 40 to visible light can be effectively improved, and the reflectivity of the specular reflection layer 40 to visible light can reach more than 98%, thereby improving the specular reflection effect. In addition, the aluminum layer can also prevent the silver layer from being oxidized after forming a dense oxide film, so as to effectively protect the silver layer and prevent the problem that the specular reflection effect of the specular reflection layer 40 is weakened due to the oxidation of the silver layer.

[0077] In some examples, the first metal layer 41 has a plurality of first sub-openings 410, and the second metal layer 42 has a plurality of second sub-openings 420. Each first sub-opening 410 and a corresponding second sub-opening 420 form an opening 401. A filling portion 43 is also provided at the inner side wall of the first sub-opening 410, and the material of the filling portion 43 is the same as the material of the second metal layer 42. That is to say, the filling portion 43 is made of aluminum material.

[0078] With such a setting, the filling portion 43 can be attached to the inner sidewall of the first sub-opening 410, thereby effectively protecting the silver layer.

[0079] It should be noted that the size of the first sub-opening 410 is smaller than that of the corresponding second sub-opening 420. After the filling portion 43 is disposed on the inner sidewall of the first sub-opening 410, the filling portion 43 can define an opening having the same size as the corresponding second sub-opening 420.

[0080] In some embodiments, as Figure 1 shown, the display screen 100 further includes a flat layer located on the side of the lens layer 30 away from the array substrate 10. The flat layer can provide a flat surface for the specular reflection layer 40 so that the specular reflection layer 40 is disposed on the flat layer.

[0081] In other embodiments, as Figure 2 and Figure 3 shown, the display screen 100 further includes a cover plate 60. The cover plate 60 is located on the side of the plurality of lenses 31 (i.e., the lens layer 30) away from the array substrate 10 and is bonded to the second encapsulation layer 52. The specular reflection layer 40 is disposed on the cover plate 60.

[0082] In this embodiment, the cover plate 60 can provide a flat surface, thereby ensuring the effective production of the specular reflection layer 40. On the other hand, the film layer on the cover plate 60 and the film layer on the array substrate 10 can be produced separately, which is conducive to improving the production efficiency of the display screen 100.

[0083] In some examples, the specular reflection layer 40 is disposed on the side of the cover plate 60 away from the array substrate 10. With such a setting, the loss of natural light when hitting the specular reflection layer 40 can be effectively reduced or avoided, thereby improving the specular reflection effect of the display screen 100.

[0084] In other examples, the specular reflection layer 40 is disposed on the side of the cover plate 60 close to the array substrate 10. With such a setting, the encapsulation of the specular reflection layer 40 can be achieved after the cover plate 60 is bonded to the second encapsulation layer 52, thereby alleviating the problem that the specular reflection effect of the display screen 100 is weakened due to the oxidation of the specular reflection layer 40.

[0085] As an example, the cover plate 60 can be made of a transparent glass material, thereby ensuring that the display screen 100 has a good display effect. In addition, the cover plate 60 and the second encapsulation layer 52 can be bonded through an adhesive. For example, the adhesive can be an optical adhesive. In this case, the cover plate 60 can be installed by a frame pasting method. That is, the adhesive is arranged around the cover plate 60 and is pasted and fixed to the second encapsulation layer 52.

[0086] In some embodiments, as Figure 1As shown, the array substrate 10 includes a substrate 11 and a driving circuit layer 12 located on the substrate 11. A plurality of micro light-emitting diodes 21 are electrically connected to the driving circuit layer 12. Through the driving circuit layer 12, some or all of the micro light-emitting diodes 21 can be driven to realize the display function of the display screen 100.

[0087] It is worth noting that the driving circuit layer 12 is made of a metal material, which can cooperate with the mirror reflection layer 40 (or the mirror reflection layer 40 and the first encapsulation layer 51) to reflect ambient light, thereby improving the mirror reflection effect of the display screen 100.

[0088] For the specific structure of the driving circuit layer 12, reference can be made to the structure of the existing driving circuit layer for driving the micro light-emitting diodes 21, and details will not be elaborated here.

[0089] As an example, all the micro light-emitting diodes 21 can be transferred to the array substrate 10 through a bonding process to realize the electrical connection and fixation between the micro light-emitting diodes 21 and the driving circuit layer 12.

[0090] In some examples, the substrate 11 can be made of glass material.

[0091] Some embodiments of the present application further provide a display device. As Figure 7 shown, the display device 1000 includes the display screen 100 described in any of the above embodiments.

[0092] Since it includes the display screen 100, the display device 1000 has the above technical effects of the display screen 100, and details will not be elaborated here. The display device 1000 provided by the embodiments of the present application can be used as a mirror and can also display images.

[0093] In some embodiments, please continue to refer to Figure 7 , the display device 1000 further includes a mounting bracket 200, and the display screen 100 is fixed on the mounting bracket 200 for the convenience of users.
