[0001] The present application belongs to the technical field of electronic products, and specifically relates to a display screen and an electronic device. Background Art

[0002] The display screen is the main component of an electronic device to realize the display function. The display screen usually includes a protective layer, a display layer and a support layer. The protective layer is arranged on the outermost side of the display screen to protect the display layer from being scratched, pressed and dropped, that is, the protective layer is used to protect the display layer, and the support layer is used to support the display layer.

[0003] The protective layer is generally made of UTG (Ultra Thin Glass), which can improve the display layer's ability to resist puncture by sharp objects. However, since glass is a brittle material, the protective layer has poor bending ability and is easily broken after impact, which also results in limited protective ability of the protective layer and a high failure rate.

[0004] In summary, the protective layer of the display screen involved in the related art has the problems of high failure rate, poor bending ability and low protection ability for the display layer. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a display screen and an electronic device that can solve the problems of high failure rate, poor bending ability and low protection ability of the display layer in the related art.

[0006] The present application provides a display screen, comprising a display layer and a protective layer.

[0007] The display layer and the protective layer are stacked in sequence in the thickness direction of the display screen, the display layer includes a plurality of pixel areas arranged in an array, the protective layer is a metal layer, and a light-through hole is opened on the protective layer, and the light-through hole is arranged opposite to the pixel area in the thickness direction of the display screen.

[0008] An embodiment of the present application provides an electronic device, comprising a housing and the display screen described above, wherein the display screen is connected to the housing.

[0009] In the embodiment of the present application, since the protective layer is a metal layer and the metal layer has certain strength and toughness, the failure rate of the protective layer is low, and this arrangement can effectively improve the mechanical properties and bending properties of the protective layer. At the same time, the structural strength of the display screen can be improved, that is, the protection ability of the protective layer to the display layer can be improved. Moreover, since a light-through hole is provided on the protective layer, the light-through hole and the pixel area of ​​the display layer are arranged relative to each other in the thickness direction of the display screen, so that the light coming out of the pixel area can be emitted through the light-through hole, which can meet the display effect of the display screen.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0020] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] The display screen disclosed in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0022] Please refer to Figures 1 - 5 The present application discloses a display screen, which includes a display layer 110 and a protective layer 120 .

[0023] The display layer 110 and the protective layer 120 are stacked in sequence in the thickness direction of the display screen. The display layer 110 is the main component of the display screen to realize the display function. Specifically, the display layer 110 includes a plurality of pixel areas arranged in an array. The pixel area is the area of ​​the display layer 110 used for emitting light. The plurality of pixel areas arranged in an array can enable the display screen to display images. When the display screen is a liquid crystal display screen, the pixel area here can be the area where the filter unit of the color filter layer is located; when the display screen is an organic light-emitting display screen, the pixel area here can be the area where the light-emitting pixels of the organic light-emitting layer are located.

[0024] The protective layer 120 has the function of protecting the display layer 110, and the protective layer 120 is a metal layer, that is, the material of the protective layer 120 is metal, which makes the protective layer 120 have good bending performance and impact resistance, and thus the protective layer 120 can better protect the display layer 110. The protective layer 120 is provided with a light hole 130, and in the thickness direction of the display screen, the light hole 130 is arranged opposite to the pixel area, so that the light emitted from the pixel area can be emitted through the light hole 130, and thus the protective layer 120 is not easy to affect the display effect of the display screen.

[0025] Specifically, the processing method of the light hole 130 can be pixel-level lithography, that is, the pixel-level lithography process is used to remove the local metal material of the protective layer 120 at the position corresponding to the pixel area of ​​the protective layer 120 by exposure, development and etching, so as to form the light hole 130, and the pixel-level lithography process can improve the accuracy of the relative setting of the light hole 130 and the pixel area, specifically, improve the alignment accuracy of the center of the light hole 130 and the center of the pixel area.

[0026] In the embodiment of the present application, since the protective layer 120 is a metal layer and the metal layer has certain strength and toughness, the failure rate of the protective layer 120 is relatively low. Moreover, this setting method can effectively improve the mechanical properties and bending properties of the protective layer 120. At the same time, it can improve the structural strength of the display screen, that is, improve the protection ability of the protective layer 120 for the display layer 110. And because the light-transmitting holes 130 are formed in the protective layer 120, in the thickness direction of the display screen, the light-transmitting holes 130 are arranged opposite to the pixel regions of the display layer 110. This enables the light coming out of the pixel regions to be emitted through the light-transmitting holes 130, which can meet the display effect of the display screen.

[0027] Optionally, please refer to Figure 1 , to prevent dust and other impurities from entering the light-transmitting holes 130 and affecting the light-emitting effect of the display screen, a protective structure can be additionally provided on the protective layer 120. This protective structure can prevent dust and other impurities from entering the light-transmitting holes 130. Specifically, the protective structure can be a scratch-resistant layer 210. The scratch-resistant layer 210 and the protective layer 120 can be adhesively connected through a first adhesive layer 220. While the scratch-resistant layer 210 plays a protective role, it can prevent other foreign objects from scratching the display screen. The first adhesive layer 220 can be an optical adhesive, that is, while the first adhesive layer 220 plays a connecting role, it does not affect the light-emitting effect of the display screen.

[0028] In another embodiment, please refer to Figure 3 , the display screen can further include a light-transmitting part 140. The light-transmitting part 140 is filled in the light-transmitting holes 130. The light-transmitting part 140 can prevent dust and other impurities from entering the light-transmitting holes 130. And after adopting this setting method, in the embodiment of the present application, it is not necessary to additionally provide a protective structure on the protective layer 120. This can reduce the overall thickness of the display screen and lower the production cost. Of course, based on this embodiment, when ensuring that the overall thickness of the display screen meets the usage requirements and controlling the production cost, the above-mentioned scratch-resistant layer 210 can also be provided on the protective layer 120. At this time, the scratch-resistant layer 210 and the protective layer 120 can play a dual role in protecting the display layer 110.

[0029] Optionally, the material of the light-transmitting part 140 can be transparent resin, and the transparent resin has good light-transmitting performance. Of course, the material of the light-transmitting part 140 can also be other light-transmitting polymer materials, and the embodiment of the present application does not make specific limitations on this.

[0030] Optionally, in the thickness direction of the display screen, the orthographic projection contour line of the light-transmitting holes 130 can be located outside the orthographic projection contour line of the pixel regions, that is, the size of the light-transmitting holes 130 can be larger than the size of the pixel regions.

[0031] In another embodiment, in the thickness direction of the display screen, the orthographic projection contour line of the light-transmitting hole 130 coincides with the orthographic projection contour line of the pixel region, or the orthographic projection contour line of the light-transmitting hole 130 is located within the orthographic projection contour line of the pixel region, that is, the size of the light-transmitting hole 130 is equal to or smaller than the size of the pixel region. Furthermore, when the light-transmitting hole 130 does not affect the light-emitting effect of the pixel region, the size of the light-transmitting hole 130 can be designed to be as small as possible to avoid affecting the structural strength of the protective layer 120, and further avoid affecting the structural strength of the display screen.

[0032] Optionally, the number of the light-transmitting holes 130 can be at least two, and the light-transmitting holes 130 are arranged at intervals on the protective layer 120. In the thickness direction of the display screen, the light-transmitting holes 130 can be arranged opposite to a plurality of pixel regions, that is, a plurality of pixel regions can be arranged opposite to the same light-transmitting hole 130, so that the light emitted by the plurality of pixel regions can be emitted from the same light-transmitting hole 130.

[0033] In another embodiment, in the thickness direction of the display screen, each light-transmitting hole 130 corresponds to each pixel region one by one, that is, one light-transmitting hole 130 is arranged corresponding to one pixel region, so that the light emitted by one pixel region can be emitted from the corresponding one light-transmitting hole 130. That is, at this time, the size of the light-transmitting hole 130 is small, which can avoid affecting the local structural strength of the protective layer 120.

[0034] Optionally, for the convenience of processing and designing the protective layer 120, the light-transmitting areas of the light-transmitting holes 130 can be equal, that is, the sizes of the light-transmitting holes 130 can be the same, and the shapes of the light-transmitting holes 130 can also be the same.

[0035] In another embodiment, since the sizes and shapes of the pixel regions in different regions of the display screen are different, in order to avoid affecting the light-emitting effect of the display screen, please refer to Figure 2 ., the light-transmitting areas of the light-transmitting holes 130 can be different, and the shapes of the light-transmitting holes 130 can also be different. Specifically, the at least two light-transmitting holes 130 can include a first light-transmitting hole 131 and a second light-transmitting hole 132. The light-transmitting area of the first light-transmitting hole 131 is different from the light-transmitting area of the second light-transmitting hole 132, and the shape of the first light-transmitting hole 131 is also different from the shape of the second light-transmitting hole 132, so that the first light-transmitting hole 131 and the second light-transmitting hole 132 can adapt to pixel regions of different sizes and shapes.

[0036] Optionally, the shape of the first light-transmitting hole 131 can be square, and the shape of the second light-transmitting hole 132 can be rectangular. Of course, the first light-transmitting hole 131 and the second light-transmitting hole 132 can also be other shapes, and the embodiments of the present application do not make specific limitations thereto.

[0037] Optionally, the display screen may include a polarizing layer 150, which may filter and adjust light entering the display screen from the outside, so that the user can clearly see the image displayed on the display screen under the sun. Of course, the display screen may also not include the polarizing layer 150.

[0038] In this embodiment, in the thickness direction of the display screen, the polarizing layer 150, the protective layer 120 and the display layer 110 are stacked in sequence, that is, the protective layer 120 is located between the polarizing layer 150 and the display layer 110, or the protective layer 120, the polarizing layer 150 and the display layer 110 are stacked in sequence, that is, the polarizing layer 150 is located between the protective layer 120 and the display layer 110.

[0039] Specifically, please refer to Figure 1 and Figure 3 When the polarizing layer 150 is located between the protective layer 120 and the display layer 110, that is, the polarizing layer 150 is located on the side of the protective layer 120 away from the anti-scratch layer 210, at this time, the protective layer 120 can protect the polarizing layer 150 and the display layer 110 at the same time, and the protective layer 120 and the polarizing layer 150 can be bonded together by the second adhesive layer 230. The second adhesive layer 230 can have the same structure as the first adhesive layer 220, that is, the second adhesive layer 230 can also be optical glue. While the second adhesive layer 230 plays a connecting role, it also does not affect the luminous effect of the display screen.

[0040] Please refer to Figure 4 When the protective layer 120 is located between the polarizing layer 150 and the display layer 110, that is, the anti-scratch layer 210 and the polarizing layer 150 are located on the same side of the protective layer 120, the anti-scratch layer 210 and the polarizing layer 150 can be bonded together by the first bonding layer 220, and the polarizing layer 150 and the protective layer 120 can be bonded together by the second bonding layer 230. In this embodiment, the protective layer 120 is disposed closer to the display layer 110, so that more light from the pixel area can be emitted through the light holes 130, which can improve the display brightness of the display screen to meet the user's usage requirements.

[0041] Optionally, the embodiment of the present application may use the polarizing layer 150 to filter light.

[0042] In another embodiment, please refer to Figure 5 In the embodiment of the present application, a filter layer 160 can be used to filter light, that is, the display screen can also include a filter layer 160. The filter layer 160 can replace the polarizing layer 150. The filter layer 160 can specifically be a color filter. The color filter has a better filtering effect, and thus the display effect of the display screen is better. The filter layer 160 can also solve the problem of reflection of the display screen.

[0043] In this embodiment, in the thickness direction of the display screen, the protective layer 120, the light filtering layer 160, and the display layer 110 are stacked in sequence, or the light filtering layer 160, the protective layer 120, and the display layer 110 are stacked in sequence. Specifically, when the light filtering layer 160 is located between the protective layer 120 and the display layer 110, the protective layer 120 can protect both the light filtering layer 160 and the display layer 110 at the same time. When the protective layer 120 is located between the light filtering layer 160 and the display layer 110, the protective layer 120 is disposed closer to the display layer 110. At this time, among the light rays emitted from the pixel region, more light rays can be emitted through the light passing holes 130, which can improve the display brightness of the display screen to meet the user's usage requirements. At the same time, the light emitting effect of the display screen can also be ensured.

[0044] Optionally, to ensure the structural stability of the display screen, the light filtering layer 160 and the protective layer 120 can be adhesively connected through the above-mentioned second adhesive layer 230. Of course, the light filtering layer 160 and the protective layer 120 can also be connected in other ways.

[0045] Optionally, the material of the protective layer 120 can be stainless steel, titanium, or aluminum, or the material of the protective layer 120 can be a mixed material of at least two of the above three metal materials, that is, the protective layer 120 can be a metal composite layer. The above three metal materials are relatively common and have low costs, and the protective layer 120 made thereof is more likely to meet the usage requirements for protecting the display layer 110. Of course, the material of the protective layer 120 can also be other metals.

[0046] Optionally, the thickness of the protective layer 120 can be less than 50 um, or the thickness of the protective layer 120 can be greater than 150 um.

[0047] In another embodiment, the thickness of the protective layer 120 is 50 um to 150 um, which enables the protective layer 120 to have good bending performance, impact resistance, and relatively large structural strength, while not causing the overall thickness of the display screen to be too large.

[0048] Optionally, please refer to Figure 1, the display screen may further include multiple functional layers, specifically including a third adhesive layer 240, a touch layer 250, a packaging layer 260, a backplane 270, a substrate 280, a fourth adhesive layer 310, a protective film 320, a fifth adhesive layer 330, and a support layer 340. In the thickness direction of the display screen, the anti-scratch layer 210, the first adhesive layer 220, the protective layer 120, the second adhesive layer 230, the polarizing layer 150, the third adhesive layer 240, the touch layer 250, the packaging layer 260, the display layer 110, the backplane 270, the substrate 280, the fourth adhesive layer 310, the protective film 320, the fifth adhesive layer 330, and the support layer 340 are arranged in sequence. Among them, the third adhesive layer 240 is used to connect the polarizing layer 150 and the touch layer 250, and the structure of the third adhesive layer 240 may be the same as that of the first adhesive layer 220 and the second adhesive layer 230.

[0049] Optionally, please refer to Figure 4 , in the thickness direction of the display screen, the anti-scratch layer 210, the first adhesive layer 220, the polarizing layer 150, the second adhesive layer 230, the protective layer 120, the touch layer 250, the packaging layer 260, the display layer 110, the backplane 270, the substrate 280, the fourth adhesive layer 310, the protective film 320, the fifth adhesive layer 330, and the support layer 340 may be arranged in sequence.

[0050] Optionally, please refer to Figure 5 , in the thickness direction of the display screen, the protective layer 120, the second adhesive layer 230, the light filtering layer 160, the touch layer 250, the packaging layer 260, the display layer 110, the backplane 270, the substrate 280, the fourth adhesive layer 310, the protective film 320, the fifth adhesive layer 330, and the support layer 340 may be arranged in sequence.

[0051] In the above embodiments, the touch layer 250 is used to implement the touch function of the display screen, the packaging layer 260 is used for thin film packaging, the backplane 270 is used to provide signals to thin film transistors so that the thin film transistors drive the liquid crystal of the display screen to deflect, or drive the organic light emitting layer of the display screen to emit light, the substrate 280 is used to support the display layer 110, the fourth adhesive layer 310 is used to connect the substrate 280 and the protective film 320, the fifth adhesive layer 330 is used to connect the protective film 320 and the support layer 340. The structures of the fourth adhesive layer 310 and the fifth adhesive layer 330 may be the same, and both may be pressure-sensitive adhesives. The protective film 320 has a certain protective effect, and the combination of the fourth adhesive layer 310, the protective film 320, and the fifth adhesive layer 330 can form a buffer protective layer with a buffering and protective effect, that is, the fourth adhesive layer 310, the protective film 320, and the fifth adhesive layer 330 can play a buffering and protective role between the display layer 110 and the support layer 340. The support layer 340 is used to support the above-mentioned various functional layers of the display screen, and during the folding process of the folding display screen, the support layer 340 can play a role in maintaining the shape.

[0052] Specifically, a plurality of grooves 341 arranged at intervals may be formed on the side of the support layer 340 facing away from the protective film 320. At the same time, through holes 342 may also be formed on the support layer 340, and the through holes 342 are located between the plurality of grooves 341. The design of the grooves 341 and the through holes 342 can make the display screen easier to be bent into a water droplet shape, achieve a smaller bending radius of curvature, and can achieve a better stress release effect when the display screen is bent, thereby improving the folding effect of the display screen.

[0053] Optionally, the display screen may further include a barrier layer 350, and the barrier layer 350 is disposed at the through holes 342. The barrier layer 350 can block external dust and other impurities from entering the through holes 342 to avoid affecting the folding effect of the display screen. Optionally, a metal film may be attached to the support layer 340, and the metal film may specifically be a copper foil, an aluminum sheet or other metal coatings, and the metal film can play a role in heat dissipation and conduction.

[0054] Optionally, the material of the support layer 340 may be stainless steel or titanium alloy, which can improve the anti-impact ability of the support layer 340 against blunt objects and reduce the production cost. Optionally, the thickness of the support layer 340 may be 30um, that is, the support layer 340 is made of ultra-thin metal, which can ensure the support effect on the above-mentioned various functional layers of the display screen while meeting the grounding performance and not increasing the overall thickness of the display screen.

[0055] Optionally, please refer to Figure 4 that the thickness of the scratch-resistant layer 210 may be 50um, the thickness of the first adhesive layer 220 may be 50um, the thickness of the polarizing layer 150 may be 23um, the thickness of the second adhesive layer 230 may be 50um, the thickness of the protective layer 120 may be 50um - 150um, the sum of the thicknesses of the touch layer 250, the encapsulation layer 260, the display layer 110, the backplane 270 and the substrate 280 may be 65um, the thickness of the fourth adhesive layer 310 may be 15um, the thickness of the protective film 320 may be 25um, the thickness of the fifth adhesive layer 330 may be 25um, and the thickness of the support layer 340 may be 30um.
