Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to a display component, display screen, and electronic device. Background Technology

[0002] Structural color, also known as physical color, is an optical effect caused by microstructure. It is achieved by forming a structural color layer on a transparent substrate, resulting in reflected light of specific wavelengths. This reflected light creates a color display effect. Simultaneously, the high light transmittance of the transparent substrate allows for the observation of the image on the other side of the substrate while simultaneously achieving color reflection. The fusion of this image and the reflected light creates an augmented reality effect. Due to its advantages such as colorfastness, high stability, and excellent display quality, structural color displays are widely used in display, decoration, and anti-counterfeiting fields.

[0003] However, when structural colors are used for display, interference occurs between reflected light and external light, resulting in reduced brightness of the reflected light and a deterioration in display quality. This makes it difficult for the naked eye to clearly identify the displayed information, leading to a poor user experience. Summary of the Invention

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0041] Structural color, also known as physical color, is an optical effect caused by microscopic structure. For example... Figure 1 As shown, by forming a structural color layer 20' on the transparent substrate 10', the second ray m' is reflected to obtain reflected light n' of a specific wavelength, and the reflected light n' achieves a color display effect. Simultaneously, the transparent substrate 10' has high light transmittance, allowing the image on the other side of the transparent substrate 10' to be observed while achieving reflected color display. Figure 1 Taking the indicated direction as an example, the user in Figure 1 When viewed from the left side of the transparent substrate 10' shown, the reflected light n' from the left side of the transparent substrate 10' and the first ray p' incident from the right side of the transparent substrate 10', i.e., the external ray, can be observed simultaneously. Through the fusion of the first ray p' and the reflected light n', both the real-world image on the right and the image intended to be displayed through the structural color layer 20' can be seen, achieving an enhanced reality display effect. Because structural color displays have advantages such as non-fading, high stability, and good display effects, they are widely used in display, decoration, and anti-counterfeiting fields.

[0042] However, when structural colors are used for display, interference occurs between the reflected light n' and the first ray p', resulting in a decrease in the brightness of the reflected light n' and a deterioration in the display effect. This makes it difficult for the naked eye to clearly identify the displayed information, leading to a poor user experience.

[0043] To address the aforementioned technical issues, this disclosure provides a display component, a display screen, and an electronic device. By setting a light-shielding layer between the structural color layer and the transparent substrate to block the first light source, interference between the first light source and the reflected light is avoided, ensuring the amount of reflected light is guaranteed, thereby improving the visibility of the reflected light and thus enhancing the display brightness and color rendering of the display component, and improving the user experience.

[0044] According to an exemplary embodiment, such as Figures 2-12 As shown, this disclosure provides a display assembly including a transparent substrate 10, a structural color layer 20, and a light-shielding layer 30. The structural color layer 20 is disposed on the transparent substrate 10, and the light-shielding layer 30 is disposed between the structural color layer 20 and the transparent substrate 10. The light-shielding layer 30 is used to block a portion of a first light ray p that passes through the transparent substrate 10 and is incident on the structural color layer 20, so that the light intensity of the first light ray p that passes through the transparent substrate 10 and is incident on the structural color layer 20 is less than or equal to the light intensity of the reflected light n, wherein the reflected light n is formed based on the reflection of a second light ray m incident from the side away from the transparent substrate 10. When the light intensity of the first ray p is greater than the light intensity of the reflected light n, the display effect of the display component will deteriorate, and the naked eye will find it difficult to accurately identify the display information. However, by setting up a light-shielding layer 10 to block part of the incident first ray p, the amount of light incident on the first ray p is reduced, thereby making the light intensity of the reflected light n that is to be displayed after being reflected by the structural color layer 20 higher. This can avoid the first ray p interfering with the reflected light n, effectively improving the light intensity of the reflected light n, thereby improving the display brightness and clarity.

[0045] The transparent substrate 10 can be an organic or inorganic transparent material with high light transmittance to facilitate light transmission and improve display performance. The light-shielding layer 30 can contain a black, opaque or poorly transparent material to partially block or filter the first light ray p, thereby reducing its intensity. The structural color layer 20 can include nanopatterns formed on the transparent substrate 10. These nanopatterns can be, for example, stripes, spheres, prisms, etc. Those skilled in the art can design the structure of the structural color layer 20 according to actual color display needs, and this embodiment does not impose excessive limitations on this.

[0046] In this embodiment of the present disclosure, by setting a light-shielding layer between the structural color layer and the transparent base layer to block part of the first light, interference between the first light and the reflected light is avoided, the light intensity of the first light incident on the display component is reduced, and the amount of reflected light is guaranteed, so as to improve the recognition of the reflected light, thereby improving the display brightness and color rendering of the display component and enhancing the user experience.

[0047] In some embodiments, the structure color layer 20 includes a plurality of structure color pixels 201 arranged in an array, and the light-shielding layer 30 includes a plurality of light-shielding portions 31. At least a portion of the structure color pixels 201 have a corresponding light-shielding portion 31 in their respective areas. The light-shielding portions 31 can be uniformly or non-uniformly arranged. In one example, each structure color pixel 201 may have a corresponding light-shielding portion 31, thereby partially blocking the first light rays incident on the area corresponding to each structure color pixel 201, thus improving the overall display effect of the display component. In another example, only a portion of the structure color pixels 201 have a corresponding light-shielding portion 31. Specifically, the light-shielding portion 31 may be provided only for structure color pixels 201 in areas with high display effect requirements or areas displaying important information. For example, the structure color pixels 201 in the central area may have a corresponding light-shielding portion 31, while the structure color pixels 201 in the edge areas may not have a corresponding light-shielding portion 31. Of course, it is understood that the specific area and number of the light-shielding part 31 can be adjusted by those skilled in the art according to actual needs, and the present disclosure does not impose too many restrictions on this.

[0048] In some embodiments, the structural color layer 20 includes multiple groups of pixels arranged in an array (the entire... Figure 4 Each pixel group comprises three groups of pixel units 21 displaying different colors. These three groups of pixel units 21 can be arranged according to a red-green-blue pattern. At least some of the structural color pixels 201 in each pixel unit group 21 are provided with light-shielding portions 31. To avoid uneven brightness during display, multiple light-shielding portions 31 are evenly distributed. For example, multiple light-shielding portions 31 are arrayed on the transparent base layer 10 to ensure uniform display effect across the entire display area.

[0049] When the light-shielding part 31 is set with each pixel unit group 21 as the smallest corresponding unit, the projection area of ​​each pixel unit group 21 on the transparent base layer 10 can be smaller than the projection area of ​​the structural color pixel 201. For example, the light-shielding part 31 is only set in a part of the pixel unit group 21 to partially block the incident light amount of the first light ray p. While ensuring the incident amount of the first light ray p, the incident light amount of the first light ray p can also be reduced.

[0050] When the light-shielding part 31 is set with each structural color pixel 201 as the smallest corresponding unit, the projected area of ​​the light-shielding part 31 on the transparent base layer 10 can be smaller than the projected area of ​​the structural color pixel 201, so as to avoid excessive blocking of the first light ray p, which would affect the stereoscopic display effect. Of course, it is understandable that when the requirements for display effect are low, the area where some structural color pixels 201 are located is correspondingly provided with the light-shielding part 31, and the projected area of ​​the light-shielding part 31 on the transparent base layer 10 can also be greater than or equal to the projected area of ​​the structural color pixel 201. Since only some structural color pixels 201 are correspondingly provided with the light-shielding part 31, even if the area of ​​the light-shielding part 31 is greater than or equal to the area of ​​the structural color pixel 201, it will not completely block the first light ray p, and a certain stereoscopic display effect can still be achieved.

[0051] In some embodiments, each structural color pixel 201 in the structural color layer 20 is provided with a light-shielding part 31 in its corresponding area. The projection of the structural color pixel 201 onto the transparent substrate 10 overlaps with the projection of the light-shielding part 31 onto the transparent substrate 10. The projection area of ​​the structural color pixel 201 onto the transparent substrate 10 is larger than the projection area of ​​the light-shielding part 31 onto the transparent substrate 10; that is, the projection area of ​​the light-shielding part 31 onto the transparent substrate 10 is smaller than the projection area of ​​the structural color pixel 201. This ensures that while reducing the brightness of the first ray p, the first ray p is not completely blocked, thus not affecting the display effect.

[0052] In some embodiments, both the structural color pixel 201 and the light-shielding portion 31 are square in shape. For example... Figures 4-6 As shown, the side length of the structural color pixel 201 is a first length L1, and the side length of the light-shielding part 31 is a second length L2. The first length L1 is greater than the second length L2, so that the projected area of ​​the structural color pixel 201 on the transparent substrate 10 is greater than the projected area of ​​the light-shielding part 31 on the transparent substrate 10. The projection of the light-shielding part 31 on the transparent substrate 10 can be located at the center of the projection of the structural color pixel 201 on the transparent substrate 10 to ensure uniform light transmission.

[0053] Wherein, the first length L1 can be the pixel pitch of the display. The pixel pitch depends on the size and resolution of the display. When the size and resolution are the same, most displays have essentially the same pixel pitch. The relationship between pixel pitch and display size and resolution is shown in Table 1 below. For example, in the case of UHD (Ultra High Definition) 4K resolution, the pixel pitch is 37 micrometers when the display size is 15 inches; and 80 micrometers when the display size is 32 inches. As another example, in the case of FHD (Full High Definition) 2K resolution, the pixel pitch is 49 micrometers when the display size is 15 inches; and 104 micrometers when the display size is 32 inches.

[0054] Table 1 Pixel pitch at different resolutions and sizes

[0055]

[0056]

[0057] In some embodiments, the second length L2 is less than a preset threshold, and the area of ​​the light-shielding part 31 is greater than or equal to a preset area. For example, the preset threshold is 5 to 10 micrometers, and the preset area is 10 ± 2 square micrometers. Since the eye has a visual decomposition effect when recognizing an image, a small area of ​​light obstruction will not be perceived by the naked eye when there is a gap between the eye and the image. Considering the distance between the user's eye and the display component, the second length L2 is usually more than 1 millimeter before it is easily perceived by the naked eye. Therefore, in this embodiment, the second length L2 is set to be less than the preset threshold, which is 5 to 10 micrometers. This ensures that the light-shielding part 31 does not completely block the first light and that no black spots are perceived by the naked eye, thus guaranteeing the display effect. Furthermore, the area of ​​the light-shielding part 31 being greater than or equal to the preset area ensures that the light-shielding part 31 will not fail to provide light shielding due to its small area, thus guaranteeing a certain level of light shielding effect. Of course, it is understood that the specific size of the preset threshold and preset area can be set according to the actual size of the pixel pitch. Generally, the larger the pixel pitch, the larger the preset threshold and preset area, and the smaller the pixel pitch, the smaller the preset threshold and preset area. The specific size of the preset threshold and preset area can be determined by those skilled in the art according to actual needs. This disclosure does not impose too many restrictions on this.

[0058] In some embodiments, the display component further includes an insulating layer 40. The insulating layer 40 is used to provide insulation and protection for the structural color layer 20 and the light-shielding layer 30. The insulating layer 40 can be made of organic insulating materials such as silicone, rubber, and plastic, or inorganic insulating materials such as glass, silicon oxide, and aluminum oxide. This disclosure does not impose excessive limitations on this aspect.

[0059] In one example, such as Figure 12 As shown, the insulating layer 40 includes a first insulating layer 41, which is disposed between the transparent base layer 10 and the structural color layer 20, and covers the light-shielding layer 30. The first insulating layer 41 is used to achieve insulation between the light-shielding layer 30 and the structural color layer 20, and can also planarize the light-shielding layer 30, so as to facilitate the further formation of the structural color layer 20 on the first insulating layer 41.

[0060] In one example, such as Figure 12 As shown, the insulating layer 40 further includes a second insulating layer 42, which is disposed on the side of the first insulating layer 41 away from the light-shielding layer 30, so as to... Figure 12 Taking the orientation shown as an example, the second insulating layer 42 is disposed above the first insulating layer 41. The second insulating layer 42 covers the structural color layer 20 and is connected to the first insulating layer 41 to form an insulating layer 40, so that the structural color layer 20 is completely wrapped by the insulating layer 40, improving the insulation and isolation effect, thereby improving the stability of the display component.

[0061] In some embodiments, the materials of the transparent base layer 10, the structural color layer 20, and the light-shielding layer 30 can be selected from a variety of options.

[0062] In some embodiments, the transparent base layer 10 includes at least one selected from the following: a PET (Polyethylene terephthalate) layer, a PI (Polyimide) layer, a PDMS (Polydimethylsiloxane) layer, a PMMA (Polymethyl methacrylate) layer, and a glass layer. The transparent base layer 10 can be one of the following layers: PET, PI, PDMS, PMMA, and glass, or several of these layers can be stacked together. Of course, it is understood that the transparent base layer 10 can also be selected from other transparent or highly transparent materials. This disclosure does not impose excessive limitations on this, and those skilled in the art can choose according to actual needs.

[0063] In some embodiments, the structural color layer 20 includes at least one of a transparent metal oxide layer, a titanium oxide layer, a zirconium oxide layer, and a silicon oxide layer. The structural color layer 20 can be one of these, or several of them can be stacked together. Different materials of the structural color layer 20 can also be selected depending on the region. This disclosure does not impose excessive restrictions on the specific material of the structural color layer 20; those skilled in the art can set it according to actual needs.

[0064] In some embodiments, the light-shielding layer 30 includes at least one of a black metal oxide layer and a black PI layer. Setting the light-shielding layer 30 to black can effectively block light. The light-shielding layer 30 can be a black metal oxide layer, a black PI layer, or both layered together. Of course, it is understood that the light-shielding layer 30 can also be made of other materials with low light transmittance, or by coating other materials with a black coating. This disclosure does not impose excessive limitations on these aspects, and those skilled in the art can choose according to actual needs.

[0065] In one example, the light-shielding layer 30 is deposited on the transparent substrate 10. When the light-shielding layer 30 is formed by deposition, the material of the light-shielding layer 30 can be a black metal oxide. The process of depositing the light-shielding layer 30 is as follows: plasma deposition (Sputtering), PR (Photoreist) coating, exposure (photo-lithography), etching (Etch), development (develop), photoreist stripping (strip), and cleaning (Cleaning), finally obtaining the desired light-shielding layer 30.

[0066] In another example, the light-shielding layer 30 can be formed on the transparent substrate 10 by coating. When the light-shielding layer 30 is formed by coating, the material of the light-shielding layer 30 can be black PI. The process of forming the light-shielding layer 30 by coating is as follows: liquid material coating, PR coating, exposure, etching, development, photoresist stripping, and cleaning, finally obtaining the desired light-shielding layer 30.

[0067] It is worth noting that both the transparent substrate 10 and the light-shielding layer 30 can be made of PI material. The basic composition of the PI material used in the transparent substrate 10 and the light-shielding layer 30 is the same; the only difference is the color. The transparent PI material used in the transparent substrate 10 does not require additional pigments, while the black PI material used in the light-shielding layer 30 requires the addition of black pigments, such as chlorinated polyethylene coatings, epoxy paints, or black lead pigments, to the transparent PI material. Of course, it is understood that the specific materials and material compositions of the transparent substrate 10 and the light-shielding layer 30 are not limited to the examples listed in the embodiments of this disclosure, and those skilled in the art can make selections according to actual needs. The following will combine... Figures 7-12 This describes the formation process of the display component in the embodiments of this disclosure.

[0068] First, such as Figure 7 As shown, a transparent base layer 10 is provided. Then, as... Figure 8 As shown, a light-shielding layer material 301 is deposited or coated on the transparent substrate 10. The materials and processes involved in the deposition or coating have been described above and will not be repeated here. Then, as... Figure 9As shown, the light-shielding layer material 301 is etched to form the light-shielding layer 30. The etching process can employ either physical etching or chemical etching. Then, as... Figure 10 As shown, a first insulating layer 41 is formed on the transparent substrate 10 and the light-shielding layer 30. Then, as... Figure 11 As shown, a structural color layer 20 is formed on the first insulating layer 41. Finally, as... Figure 12 As shown, a second insulating layer 42 is formed on the structural color layer 20 and the first insulating layer 41 to achieve insulation protection for the structural color layer 20 and the light-shielding layer 30. The first insulating layer 41 and the second insulating layer 42 together constitute the insulating layer 40. The insulating layer 40 can be formed by sputtering or CVD (Chemical Vapor Deposition). The materials of the first insulating layer 41 and the second insulating layer 42 can be inorganic insulating materials such as silicon oxide and silicon nitride. The materials of the first insulating layer 41 and the second insulating layer 42 can be the same or different, and this embodiment does not impose too many restrictions on this. Among them, sputtering is a commonly used thin film preparation method. By applying high-energy particles to the surface of the target material, atoms or molecules in the target material are sputtered out and deposited on the surface of the substrate material to form the desired thin film. Chemical vapor deposition is a chemical technology that introduces gaseous or liquid reactants containing thin film elements into a reaction chamber to generate a thin film through a chemical reaction on the substrate surface.

[0069] According to an exemplary embodiment, such as Figures 2-12 As shown in the illustration, this disclosure provides a display screen, which includes the display components described in the above embodiments. The display screen can be a head-up display screen in a car, a display screen on a wearable device, a display screen simply used for display purposes, or a large-screen component, etc. The display components include a transparent substrate 10, a structural color layer 20, and a light-shielding layer 30. The structural color layer 20 is disposed on the transparent substrate 10, and the light-shielding layer 30 is disposed between the structural color layer 20 and the transparent substrate 10. The light-shielding layer 30 is used to block a first light ray p that passes through the transparent substrate 10 and is incident on the structural color layer 20, so that the light intensity of the first light ray p that passes through the transparent substrate 10 and is incident on the structural color layer 20 is less than or equal to the light intensity of the reflected light n, wherein the reflected light n is formed based on the reflection of a second light ray m incident from the side away from the transparent substrate 10. Figure 2Taking the orientation shown as an example, the user can simultaneously observe the reflected light n from the left side of the transparent substrate 10 and the first light p incident from the right side of the transparent substrate 10. By merging the first light p with the reflected light n, the user can simultaneously see the real image on the right and the image that is expected to be displayed through the structural color layer 20, thereby achieving the effect of augmented reality display. At the same time, since a light-shielding layer is set between the structural color layer and the transparent substrate to block the first light, interference between the first light and the reflected light can be avoided, ensuring the amount of reflected light, thereby improving the recognition of the reflected light and thus improving the display brightness and color rendering of the display components.

[0070] According to an exemplary embodiment, such as Figures 2-12 As shown, this disclosure provides an electronic device, which can be a mobile terminal, laptop computer, smartwatch, smart bracelet, automobile, electric bicycle, wearable display device, or other electronic device with display function. The electronic device includes the display component as described in the above embodiments, or the display screen as described in the above embodiments.

[0071] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the claims.

[0072] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
