Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display screen and a display device. Background Technology

[0002] With the rapid development of display technology, display products, capable of displaying rich and varied information, are increasingly being used in various fields. Currently, display devices with specular reflection capabilities typically use liquid crystal displays (LCDs), which mainly rely on polarizers to achieve specular reflection.

[0003] However, the polarizer has a low reflectivity, resulting in poor specular reflection; and the LCD's low brightness results in poor display quality. Summary of the Invention

[0004] This application provides a display screen and a display device to at least solve the problem of low display brightness in display devices with mirror display function in the related art.

[0005] On one hand, this application provides a display screen, which includes an array substrate, a plurality of micro light-emitting diodes (LEDs), a plurality of lenses, and a specular reflective layer. The LEDs are disposed on the array substrate, and the plurality of lenses are disposed on the side of the LEDs away from the array substrate; the specular reflective layer is disposed on the side of the lenses away from the array substrate. The specular reflective layer has a plurality of openings for emitting at least a portion of the light emitted by the LEDs.

[0006] In some embodiments, the display screen further includes a first encapsulation layer on the array substrate for encapsulating a plurality of micro light-emitting diodes, wherein 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 diode.

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

[0009] In some embodiments, a plurality of micro-light-emitting diodes and a plurality of lenses correspond one-to-one, 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 disposed on the side of the plurality of lenses away from the array substrate and bonded to the second encapsulation layer, wherein the specular reflective layer is disposed on the cover plate.

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

[0012] In some embodiments, the opening fully exposes the corresponding micro-LED, and the ratio of the orthographic projection area of ​​the opening on the array substrate to the orthographic projection area of ​​the corresponding micro-LED 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 mirror reflective layer includes a first metal layer and a second metal layer sequentially stacked along a direction away from the array substrate, wherein the first metal layer is a silver layer and the second metal layer is an aluminum layer.

[0015] On the other hand, embodiments of this application also provide a display device, which includes a display screen as described in any of the above embodiments.

[0016] For the display screen provided in this application embodiment, since the micro-light-emitting diode (LED) has high luminous efficiency, it can emit strong light with less energy consumption. Therefore, the display brightness of the screen can be effectively improved after using the micro-LED. The micro-LED has high color purity, enabling it to display vivid and realistic colors, thus improving the screen's contrast. Furthermore, the micro-LED has a small size, which increases the pixel density in the display screen, thereby improving the screen's resolution. In addition, since the lens modulates the light emitted by the micro-LED, the display brightness can be further improved. On the other hand, since the micro-LED has a small size, the size of the aperture can be effectively reduced, thereby increasing the reflective area of ​​the main body of the specular reflective layer, and thus improving the specular reflection effect of the display screen. Furthermore, since the lens modulates the light emitted by the micro-LED, the light emitted by the micro-LED is focused into a smaller range, which further reduces the size of the aperture, further increasing the reflective area of ​​the main body of the specular reflective layer to improve the specular reflection effect of the display screen.

[0034] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The described technical solutions are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are only used to distinguish different technical features. The term "multiple" and similar words indicate two or more, unless otherwise expressly defined.

[0036] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0037] The use of "applies to" or "configured to" in this application implies open and inclusive language, which does not exclude the applicability to or configuration to devices performing additional tasks or steps. Additionally, the use of "based on" implies openness and inclusivity, because processes, steps, calculations, or other actions "based on" one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

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

[0039] Some embodiments of this application provide a display screen, such as Figures 1 to 3 as well as 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 mirror 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 either Micro LEDs (Light-Emitting Diodes) or Mini LEDs. When the micro-light-emitting diode 21 is a Mini LED, its size is greater than 100 μm and less than or equal to 300 μm. When the micro-light-emitting diode 21 is a Micro LED, its size is greater than or equal to 1 μm and less than or equal to 100 μm. In this embodiment, Micro LEDs are selected as the micro-light-emitting diodes 21. For example, the size of a Micro LED 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 its corresponding micro-light-emitting diode 21, so that the light is focused to a smaller angle for emission, thereby improving the display brightness of the display screen 100. Each lens 31 may correspond to one or more micro-light-emitting diodes 21.

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

[0043] In the display screen 100 provided in this embodiment, when the micro-light-emitting diode 21 is turned on, the light emitted by the micro-light-emitting diode 21 can be modulated by the corresponding lens 31 and then emitted through the opening 401, thereby realizing the display function of the display screen 100. Furthermore, the main body of the specular reflective layer 40 located outside the opening 401 can effectively reflect natural light, thereby realizing the specular reflection function of the display screen 100, allowing the user to 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 diode 21 is turned off to avoid interference with the displayed image.

[0044] On the one hand, because the micro-LED 21 has high luminous efficiency, it can emit strong light with less energy consumption. Therefore, the display brightness of the display screen 100 can be effectively improved after adopting the micro-LED 21. The micro-LED 21 has high color purity, which can present vivid and realistic colors, thereby improving the image contrast of the display screen 100. Furthermore, the micro-LED 21 has a small size, which can increase the pixel density in the display screen 100, thereby improving the resolution of the display screen 100. In addition, since the lens 31 modulates the light emitted by the micro-LED 21, the display brightness of the display screen 100 can be further improved.

[0045] On the other hand, since the micro-LED 21 has a small size, the size of the opening 401 can be effectively reduced, thereby increasing the reflective area of ​​the main body of the specular reflective layer 40 and improving the specular reflection effect of the display screen 100. Furthermore, since the lens 31 modulates the light emitted by the micro-LED 21, the light emitted by the micro-LED 21 is concentrated into a smaller range, which further reduces the size of the opening 401, thereby further increasing the reflective area of ​​the main body of the specular reflective layer 40 and improving the specular reflection effect of the display screen 100.

[0046] It is worth noting that for displays with specular reflection capabilities, ambient light is typically quite intense due to limitations in their usage scenarios. If the display function needs to be used under high-intensity ambient light, the display needs to be adjusted to a higher brightness to reduce interference from ambient light when the user views the screen. However, the display screen 100 provided in this embodiment utilizes the high luminous efficiency of the micro-light-emitting diode 21 and combines this with the lens 31 to focus the light emitted by the micro-light-emitting diode 21, thereby achieving high brightness and effectively reducing interference from high-intensity ambient light when the user views the display screen 100. Furthermore, the main body of the specular reflection layer 40 occupies a relatively large area, effectively ensuring that the display screen 100 functions as a mirror.

[0047] In some embodiments, each opening 401 may be located above a plurality of micro-light-emitting diodes 21, thereby emitting light emitted by the plurality of micro-light-emitting diodes 21. In this case, the opening 401 has a relatively large size, thereby increasing the amount of light emitted by the display screen 100, which is beneficial to improving the display brightness of the display screen 100.

[0048] In other embodiments, each opening 401 may be located above a micro LED 21, thereby emitting light emitted by that micro LED 21. As an example, each opening 401 may expose at least a portion of its corresponding micro LED 21. For example, each opening 401 may expose a portion of its corresponding micro LED 21 (such as half of the micro LED 21); or, each opening 401 may expose the entire corresponding micro LED 21.

[0049] With each opening 401 located above a corresponding micro light-emitting diode 21, the size of the opening 401 can be effectively reduced, thereby increasing the reflective area of ​​the main body of the specular reflective layer 40 and improving the specular reflection effect of the display screen 100.

[0050] In some examples, multiple lenses 31 can correspond one-to-one with multiple micro-light-emitting diodes 21. As an example, multiple micro-light-emitting diodes 21 can be arranged in an array, and correspondingly, multiple lenses 31 and multiple openings 401 are also arranged in an array, so that each micro-light-emitting diode 21 is provided with a lens 31 and an opening 401 above it in sequence, 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 emitting different colors of light can constitute a light-emitting unit, and multiple light-emitting units are arranged in an array on the array substrate 10. Each light-emitting unit may include, for example, multiple micro-light-emitting diodes 21 emitting red, green, and blue light respectively. This allows the display screen 100 to display color images.

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

[0053] With this configuration, the first encapsulation layer 51 can encapsulate the micro-LED 21, thereby improving its stability and lifespan. Furthermore, it can reflect the side-emitted light from the micro-LED 21 to the front-emitted light, significantly improving its light emission performance. Additionally, with part of the structure of the first encapsulation layer 51 exposed by the opening 401, the first encapsulation layer 51 can also reflect ambient light, thus enhancing the specular reflection effect of the display screen 100.

[0054] As an example, the first encapsulation layer 51 includes a main material layer and microsphere structures located within the main material layer. By controlling the particle size and arrangement of the microsphere structures, 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. Exemplarily, the microsphere structures can be nanoparticles, and the material of the microsphere structures can be titanium dioxide.

[0055] In some examples, such as Figure 2 As shown, the thickness D1 of the first encapsulation layer 51 is less than the height D2 of the micro LED 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 LED 21, and less than the height D2 of the micro LED 21. Exemplarily, the thickness D1 of the first encapsulation layer 51 can be equal to 2 / 3, 3 / 4, or 4 / 5 of the height D2 of the micro LED 21, etc.

[0056] In other examples, such as Figure 3 As shown, the thickness D1 of the first encapsulation layer 51 is equal to the height D2 of the micro-LED 21. In this case, the surface of the first encapsulation layer 51 away from the array substrate 10 is flush with the surface of the micro-LED 21 away from the array substrate 10. Therefore, light emitted from the side of the micro-LED 21 can be reflected by the first encapsulation layer 51 as much as possible and exit from the front of the micro-LED 21, thus improving the front light emission efficiency of the micro-LED 21. Furthermore, the reflection by the first encapsulation layer 51 can effectively reduce the amount of light emitted from the side of the micro-LED 21 entering the light emission position of adjacent micro-LEDs 21, thereby avoiding the problem of light crosstalk between multiple adjacent micro-LEDs 21. In addition, the top plane of the first encapsulation layer 51 and the micro-LED 21 can form a continuous surface, so that the lens layer 30 can be directly arranged on this continuous surface, which helps to reduce the thickness of the display screen 100.

[0057] In some embodiments, please continue reading Figure 2 and Figure 3 The display screen 100 also includes a second encapsulation layer 52 located on the first encapsulation layer 51. The second encapsulation layer 52 covers a plurality of micro light-emitting diodes 21, and a plurality of lenses 31 are disposed on the second encapsulation layer 52. 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 easily extracted.

[0058] By providing a second encapsulation layer 52, the top of the micro-LED 21 can be encapsulated and protected, preventing the micro-LED 21 from being susceptible to risks such as water and oxygen corrosion. Furthermore, the second encapsulation layer 52 can form a planarized surface, which facilitates the fabrication of the lens 31. On the other hand, the thickness of the second encapsulation layer 52 can be adjusted as needed. This allows for adjustment of the distance between the micro-LED 21 and the corresponding lens 31, thereby enabling the micro-LED 21 to achieve better light emission.

[0059] In some embodiments, such as Figure 4 As shown, each micro-LED 21 is located at the focal point F of its corresponding lens 31. This arrangement ensures that the light emitted by the micro-LED 21 forms parallel light after passing through the corresponding lens 31, allowing the light to pass smoothly through the corresponding opening 401 and thus improving the light extraction efficiency of the micro-LED 21. Furthermore, the lens 31 also provides better light focusing and more uniform light intensity distribution, thereby improving the display effect of the display screen 100.

[0060] It is worth noting that since the first encapsulation layer 51 is provided with a second encapsulation layer 52, and the thickness of the second encapsulation layer 52 is adjustable, it can be ensured that each micro-LED 21 is located at the focal point F of the corresponding lens 31.

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

[0062] In some embodiments, such as Figures 1 to 3 as well as Figure 6 As shown, each opening 401 is provided corresponding to a micro LED 21 and at least partially exposes the corresponding micro LED 21. For example, each opening 401 may expose a portion of the structure of the corresponding micro LED 21; or, each opening 401 may completely expose the corresponding micro LED 21.

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

[0064] In some examples, such as Figure 4 As 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, 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 LED 21 is converged by the corresponding lens 31 to form a beam. In this beam, the center of the light spot with the greatest intensity coincides with the geometric center O1 of the opening 401. This allows the light emitted by the micro LED 21 to be effectively emitted from the corresponding lens 31, thereby improving the light emission efficiency of the micro LED 21.

[0066] In some embodiments, each opening 401 fully exposes the corresponding micro-LED 21, and the ratio of the orthogonal projection area of ​​the opening 401 on the array substrate 10 to the orthogonal projection area of ​​the corresponding micro-LED 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 projected area of ​​the opening 401 on the array substrate 10 to the projected area of ​​the corresponding micro-light-emitting diode 21 on the array substrate 10 to be in the range of 1 to 1.5, the problem of reduced light emission efficiency of the micro-light-emitting diode 21 due to the opening 401 being too small, thus resulting in a deterioration of the display effect of the display screen 100, can be effectively avoided. At the same time, the problem of relatively small area of ​​the main body of the specular reflection layer 40 due to the opening 401 being too large, thus resulting in a deterioration of the specular reflection effect of the display screen 100, can also be avoided.

[0068] In some embodiments, the shape of the orthographic projection of the opening 401 on the array substrate 10 can be the same as the shape of the orthographic projection of the micro-light-emitting diode 21 on the array substrate 10. This can further increase the amount of light emitted by the micro-light-emitting diode 21 that exits from the corresponding opening 401, 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 other embodiments, the shape of the orthographic projection of the opening 401 onto the array substrate 10 may differ from the shape of the orthographic projection of the micro-light-emitting diode 21 onto the array substrate 10. In this case, the opening 401 may expose part of the structure of the first encapsulation layer 51, which can then reflect ambient light, thereby further enhancing the specular reflection effect of the display screen 100.

[0070] In some examples, the ratio of the projected area of ​​the opening 401 on the array substrate 10 to the projected area of ​​the corresponding micro-LED 21 on the array substrate 10 is greater than 1 and less than or equal to 1.5. In this case, the opening 401 can expose part of the structure of the first encapsulation layer 51, which can then reflect ambient light, thereby further improving the specular reflection effect of the display screen 100.

[0071] For example, the ratio of the projected area of ​​the opening 401 on the array substrate 10 to the projected area of ​​the corresponding micro-LED 21 on the array substrate 10 can be 1.1, 1.2, 1.3, 1.4 or 1.5, etc.

[0072] In some embodiments, such as Figure 5 As shown, any two adjacent openings 401 are spaced apart from each other. By spacing adjacent openings 401 apart, crosstalk between the light emitted by the two connected micro LEDs 21 at the corresponding opening 401 positions can be effectively avoided, thereby improving the display effect of the display screen 100.

[0073] It is worth noting that, Figure 5 The example shown uses a circular opening 401. The opening 401 can also be a rectangle, a rounded rectangle, or a regular polygon, etc., and this application does not limit this.

[0074] In some embodiments, the specular reflective layer 40 may be made of a metallic material. The metallic material may be, for example, at least one of aluminum and silver. These materials have high reflectivity, thereby achieving a good specular reflection effect. Furthermore, the specular reflective layer 40 may be obtained by patterning a metallic layer formed from a metallic material.

[0075] In some embodiments, such as Figure 6 As shown, the mirror reflection layer 40 includes a first metal layer 41 and a second metal layer 42 stacked sequentially along the 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] Aluminum has a lower reflectivity to visible light than silver, and both are typically less than 98%. In this embodiment, aluminum and silver layers are usually stacked, which effectively increases the reflectivity of the specular reflective layer 40 to visible light, achieving a reflectivity of over 98%, thus improving the specular reflection effect. Furthermore, the aluminum layer can prevent the silver layer from oxidizing after forming a dense oxide film, effectively protecting the silver layer and preventing oxidation that could weaken the specular reflection effect of the specular reflective layer 40.

[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 forming an opening 401. A filling portion 43 is also provided on the inner wall of the first sub-opening 410, and the material of the filling portion 43 is the same as that of the second metal layer 42. That is, the filling portion 43 is made of aluminum.

[0078] With this configuration, the filling part 43 can be used to attach to the inner wall of the first sub-opening 410, thereby effectively protecting the silver layer.

[0079] It is worth noting that the size of the first sub-opening 410 is smaller than the size of the corresponding second sub-opening 420. After the filling part 43 is provided on the inner sidewall of the first sub-opening 410, the filling part 43 can define an opening with the same size as the corresponding second sub-opening 420.

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

[0081] In other embodiments, such as Figure 2 and Figure 3 As shown, the display screen 100 also includes a cover plate 60, which is located on the side of the plurality of lenses 31 (i.e., lens layers 30) away from the array substrate 10 and is bonded to the second encapsulation layer 52. A specular reflective 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 fabrication of the specular reflective layer 40. On the other hand, the film layers on the cover plate 60 and the film layers on the array substrate 10 can be fabricated separately, which helps to improve the manufacturing efficiency of the display screen 100.

[0083] In some examples, the specular reflective layer 40 is disposed on the side of the cover plate 60 away from the array substrate 10. This arrangement can effectively reduce or avoid the loss of natural light when it hits the specular reflective layer 40, thereby improving the specular reflection effect of the display screen 100.

[0084] In other examples, the specular reflective layer 40 is disposed on the side of the cover plate 60 near the array substrate 10. This arrangement allows the specular reflective layer 40 to be encapsulated after the cover plate 60 is bonded to the second encapsulation layer 52, thereby mitigating the problem of reduced specular reflection effect of the display screen 100 due to oxidation of the specular reflective layer 40.

[0085] As an example, the cover plate 60 can be made of transparent glass to ensure that the display screen 100 has a good display effect. Furthermore, the cover plate 60 and the second encapsulation layer 52 can be bonded together with adhesive. For example, optical adhesive can be used. In this case, the cover plate 60 can be installed by frame mounting. That is, adhesive is applied around the cover plate 60 and then bonded and fixed to the second encapsulation layer 52.

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

[0087] It is worth noting that the driving circuit layer 12 is made of metal material, which can work 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] The specific structure of the driving circuit layer 12 can be set with reference to the existing structure of the driving circuit layer used to drive the micro light-emitting diode 21, and will not be described in detail here.

[0089] As an example, all micro-LEDs 21 can be transferred to the array substrate 10 by a bonding process, thereby achieving electrical connection and fixation between the micro-LEDs 21 and the driving circuit layer 12.
