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] With the continuous advancement of technology and the reduction of costs, OLED (Organic Light-Emitting Diode) display components are becoming increasingly popular. Among them, WOLED (White-Organic Light-Emitting Diode) display components have gained widespread application because the additional white pixels can improve brightness, thereby reducing screen burn-in and lowering costs.

[0003] However, traditional WOLED display modules typically employ a combination of light-emitting devices, color filters, and polarizers. The color filter enables color display, while the polarizer reduces the reflectivity of external light, thereby improving the contrast of the display and making the displayed image clearer. However, both the color filter and polarizer absorb a significant amount of light emitted by the light-emitting devices, resulting in high light loss and reduced overall brightness of the display module, affecting display quality and user experience. Furthermore, due to the high light loss, achieving the required display brightness often requires a large current. Prolonged operation of the light-emitting devices under high current also affects the lifespan of the display module. Summary of the Invention

[0004] To overcome the problems existing in the related technologies, this disclosure provides a display component, a display screen, and an electronic device.

[0005] According to a first aspect of this disclosure, a display component is provided, comprising:

[0006] Light-emitting devices are devices that emit light;

[0007] The structural color layer has structural color pixels arranged according to a preset rule, and the light emitted by the light-emitting device displays different colors after passing through the structural color pixels.

[0008] In one possible implementation, the structural color pixel includes at least one of stripes and hemispheres.

[0009] In one possible implementation, when the structural color pixel is set as a bar, the spacing between two adjacent structural color pixels ranges from 3 μm to 10 μm, and the width of each structural color pixel ranges from 50 μm to 120 μm.

[0010] In one possible implementation, the thickness of the structural color layer ranges from 100 μm to 200 μm, and the thickness of the structural color pixel ranges from 5 μm to 10 μm.

[0011] In one possible implementation, the structural color pixel includes a first structural color pixel, a second structural color pixel, and a third structural color pixel, wherein the first structural color pixel, the second structural color pixel, and the third structural color pixel are respectively used to display light of different colors.

[0012] In one possible implementation, the display component further includes a protective layer covering the light-emitting device, wherein the structural color layer is disposed on the side of the protective layer away from the light-emitting device.

[0013] In one possible implementation, the display assembly further includes a cover plate disposed on the side of the structural color layer away from the light-emitting device.

[0014] In one possible implementation, the display assembly further includes a polarizing layer disposed on the side of the cover plate away from the structural color layer.

[0015] In one possible implementation, the display assembly further includes an insulating layer disposed between the structural color layer and the cover plate.

[0016] According to a second aspect of this disclosure, a display screen is provided, including the display components described in the first aspect of this disclosure.

[0017] According to a third aspect of this disclosure, an electronic device is provided, including the display component described in the first aspect of this disclosure or the display screen described in the second aspect of this disclosure.

[0018] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: This disclosure uses a structural color layer instead of the color filter in the prior art to realize the color display of the display component, which simplifies the structure of the display component, avoids the light emitted by the light-emitting device being absorbed in large quantities, reduces light loss, and can achieve the required display brightness with a smaller display current, which is conducive to extending the service life of the light-emitting device and the display component, and improving product competitiveness and user satisfaction.

[0030] 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.

[0031] With the continuous advancement of technology and the reduction of costs, OLED (Organic Light-Emitting Diode) display components are becoming increasingly popular. Among them, WOLED (White-Organic Light-Emitting Diode) display components have gained widespread application because the additional white pixels can improve brightness, thereby reducing screen burn-in and lowering costs.

[0032] like Figures 1-2As shown, the display assembly includes a light-emitting device 10', a color filter 11', a cover plate 40', and a polarizer 12', to... Figure 1 Taking the orientation shown as an example, the light-emitting device 10', color filter 11', cover plate 40' and polarizer 12' are stacked sequentially from top to bottom. External light enters from below the display component, and the light emitted by the light-emitting device 10' exits from top to bottom.

[0033] The color filter 11' is used to achieve color display of the display component, and the polarizer 12' can reduce the reflectivity of external light, thereby improving the contrast of the display component and making the displayed image clearer. However, both the color filter 11' and the polarizer 12' absorb a large amount of light emitted by the light-emitting device 10'. The light transmittance of the color filter 11' is about 80%, resulting in a 20% light loss. The polarizer 12' typically uses a quarter-wave plate to convert between linearly polarized light and circularly polarized light, such as... Figure 2 As shown, the left side of the polarizer 12' is the first ray m' emitted by the light-emitting device 10', and the right side of the polarizer 12' is the second ray n' after the light emitted by the light-emitting device 10' passes through the polarizer 12'. That is, the polarizer 12' absorbs about 50% of the light emitted from the light-emitting device 10'. Therefore, the light emitted by the light-emitting device 10' suffers a large amount of light loss after passing through the polarizer 12', which causes the brightness of the display component to deviate. To obtain better display brightness, the input current needs to be increased.

[0034] Therefore, traditional WOLED display components have high light loss, which leads to a reduction in the overall brightness of the display components, affecting the display effect and user experience. In addition, due to the high light loss of the display components, a large current is often required to achieve the required display brightness. The long-term operation of the light-emitting devices under high current will also affect the lifespan of the display components.

[0035] To address the aforementioned technical problems, this disclosure provides a display component, a display screen, and an electronic device. The display component employs a structural color layer to achieve color rendering, simplifying the structure of the display component and preventing the light emitted by the light-emitting device from being heavily absorbed by the intermediate film layer, thereby improving the brightness of the display component. The current required to achieve the desired display brightness is reduced, which helps to extend the service life of the light-emitting device and the display component and reduce maintenance costs.

[0036] According to an exemplary embodiment, such as Figures 3-6As shown, this embodiment of the present disclosure provides a display component, which includes a light-emitting device 10 and a structural color layer 20. The light-emitting device 10 is capable of emitting light, and the light-emitting device 10 can be an OLED device capable of emitting white light, thereby enabling the display component to perform a display. Part of the white light emitted by the light-emitting device 10 can display color after passing through the structural color layer 20, while part of the white light that has not undergone color display can also enhance the overall brightness of the display component.

[0037] Reference Figure 5 and Figure 6 As shown, the structural color layer 20 has structural color pixels 21 arranged according to a preset rule. The light emitted by the light-emitting device 10 displays different colors after passing through the structural color pixels 21. Structural color is also called physical color. The light that shines on the structural color pixels 21 displays different colors after reflection, refraction, interference and other phenomena, thus achieving a color display effect. The structural color layer 20 has the advantages of being easy to fade, having high stability and good display effect.

[0038] In addition, the structural color layer 20 has the characteristic of only transmitting light of a specific wavelength and absorbing light of other wavelengths. Therefore, the structural color layer 20 can also play a similar role as a polarizer in reducing the reflectivity of external light, and will not absorb too much light emitted by the light-emitting device 10. It can be used to replace the polarizer in the display component.

[0039] In the technical solution of this disclosure, a structural color layer 20 is used to replace the color filter and polarizer, which greatly simplifies the film structure of the display component. While achieving color display through the structural color layer 20, it also avoids the excessive absorption of light emitted by the light-emitting device 10, which would lead to insufficient display brightness of the display component. By using the structural color layer 20 to replace the color filter and polarizer, the brightness of the display component can be increased by about 50%. In the prior art, in order to meet higher display brightness, the light-emitting device 10 usually requires a large current. However, if the light-emitting device 10 is in a high-current operating state for a long time, its lifespan will be reduced. However, after adopting the technical solution of this disclosure, since the light loss of the display component is reduced and the brightness is greatly improved, the operating current of the light-emitting device 10 can be reduced, thereby extending the lifespan of the light-emitting device 10 to about 2 to 2.5 times that of the original, reducing the use and maintenance costs of the display component.

[0040] In some embodiments, structural color pixels 21 are disposed on structural color layer 20. Structural color layer 20 can use a transparent material as a substrate, and structural color pixels 21 are formed on the transparent substrate by etching, deposition, or liquid printing. The structural color layer 20 can be one or a combination of several high-transmittance materials with a transmittance of 90% or higher, such as transparent PET (polyethylene glycol terephthalate), PMMA (polymethyl methacrylate), PI (polyimide), glass, and quartz. The material of structural color pixels 21 can include one or a combination of several transparent metal oxide layers, titanium oxide layers, zirconium oxide layers, and silicon oxide layers. Furthermore, structural color layer 20 and structural color pixels 21 can also use different materials in different areas. This disclosure does not impose excessive restrictions on the specific materials of structural color layer 20 and structural color pixels 21; those skilled in the art can select materials according to actual needs.

[0041] In some embodiments, the thickness of the structural color layer 20 ranges from 100 μm to 200 μm, and the thickness of the structural color pixel 21 ranges from 5 μm to 10 μm. Of course, it is understood that those skilled in the art can set the specific values ​​of the thickness of the structural color layer 20 and the thickness of the structural color pixel 21 according to actual needs, and this disclosure does not impose excessive limitations in this regard.

[0042] In some embodiments, such as Figures 5-6 As shown, the structural color pixel 21 includes at least one of strip and hemispherical shapes.

[0043] In one example, such as Figure 5 As shown, the structural color pixel 21 is strip-shaped. These strip-shaped structural color pixels 21 can be formed through etching, deposition, and other methods, offering advantages such as uniform color development, ease of processing, and precise control. Figure 5 Taking the orientation shown as an example, the structural color pixel 21 is along the first direction (that is... Figure 5 A strip structure extending in the y-direction shown, and along the second direction (i.e., Figure 5 The z-direction shown has a certain thickness. The first direction is the length direction of the structure color pixel 21, the second direction is the thickness direction of the structure color pixel 21, and the third direction (i.e., the z-direction) has a certain thickness. Figure 5The x-direction shown in the figure represents the width direction of the structural color pixel 21. Along the third direction, each structural color pixel 21 has a width W, and there is a spacing D between adjacent structural color pixels 21. The width W of each structural color pixel can be the same or different, and the spacing D between adjacent structural color pixels 21 can also be the same or different. Those skilled in the art can set these dimensions according to actual needs, and this embodiment does not impose excessive limitations on them.

[0044] In another example, such as Figure 6 As shown, the structural color pixel 21 is hemispherical. The hemispherical structural color pixel 21 can be formed by liquid printing or other methods, and can be set at the required location as needed. For example, hemispherical structural color pixels 21 with different densities and diameters can be set in different areas, which provides greater processing flexibility, but the color uniformity is relatively poor.

[0045] In another example, the structural color pixel 21 includes bars and hemispheres. Specifically, some areas of the structural color pixel 21 can be set as bars, and some areas as hemispheres. For example, the bar and hemisphere areas can be alternated or arranged in an array. This embodiment does not impose excessive restrictions on the specific setting method of the structural color pixel 21; those skilled in the art can set it according to actual needs.

[0046] Of course, it is understandable that, due to the different structures of bars and hemispheres, in order to ensure a better display effect, structural color pixel 21 is preferentially set to a bar shape.

[0047] In some embodiments, such as Figure 5 As shown, the structural color pixel 21 is set as a bar. When the structural color pixel 21 is set as a bar, the spacing D between two adjacent structural color pixels 21 ranges from 3μm to 10μm, and the width W of each structural color pixel 21 ranges from 50μm to 120μm. Furthermore, in the field of structural colors, the distance P between two adjacent structural colors is also commonly used to represent relevant parameters. Figure 5 Taking the orientation shown as an example, the distance between the left sides of two adjacent structural color pixels 21 is P. The distance P is the sum of the spacing D between the two adjacent structural color pixels 21 and the width W of the structural color pixel 21. Therefore, the range of the distance P between two adjacent structural colors is 53μm to 130μm. Of course, it is understood that the width W, spacing D, and distance P between structural color pixels 21 used to display different colors may all be different. The specific parameters of the structural color pixels 21 can be set by those skilled in the art according to actual needs, and this embodiment does not impose too many restrictions on this.

[0048] In some embodiments, the structural color pixel 21 includes a first structural color pixel 201, a second structural color pixel 202, and a third structural color pixel 203, which are used to display light of different colors. The width W between the first structural color pixel 201, the second structural color pixel 202, and the third structural color pixel 203 is different for each of them.

[0049] In one example, the first structural color pixel 201 is used to display red light, the second structural color pixel 202 is used to display green light, and the third structural color pixel 203 is used to display blue light. Therefore, in order to ensure that the light passing through the structural color pixel 21 has a specific wavelength to display the corresponding color, the width W of the structural color pixels 21 used to display red, green, and blue light are all different. For example, the width W of the first structural color pixel 201 is 120 nm, the width W of the second structural color pixel 202 is 100 nm, and the width W of the third structural color pixel 203 is 50 nm. The spacing D between adjacent structural color pixels can be the same or different, as long as the color rendering effect is guaranteed. Those skilled in the art can adjust this according to actual needs, and this disclosure does not impose excessive limitations on this aspect.

[0050] In some embodiments, the display component further includes a protective layer 30. For example... Figures 3-4 As shown, a protective layer 30 covers the light-emitting device 10, and a structural color layer 20 is disposed on the side of the protective layer 30 away from the light-emitting device 10. The protective layer 30 isolates the structural color layer 20 from the light-emitting device 10, thus protecting the light-emitting device 10. The thickness of the protective layer 30 ranges from 50 μm to 100 μm. The protective layer 30 can be made of organic insulating materials such as transparent resin. Furthermore, to avoid affecting the display brightness of the display component, the material used for the protective layer 30 has high light transmittance, for example, a transmittance of over 90%. This embodiment does not impose excessive restrictions on the specific material of the protective layer 30, as long as it achieves the protective function and does not affect light transmission. Those skilled in the art can choose according to actual needs.

[0051] In some embodiments, the display component further includes a cover plate 40. For example... Figures 3-4 As shown, the cover plate 40 is disposed on the side of the structural color layer 20 away from the light-emitting device 10. The cover plate 40 can be, for example, a glass cover plate with high light transmittance and strong hardness. The cover plate 40 covers the outermost part of the display component closest to the user and is used to protect the display component.

[0052] In some embodiments, the display component further includes an insulating layer 60. For example... Figures 3-4As shown, an insulating layer 60 is disposed between the structural color layer 20 and the cover plate 40. The insulating layer 60 serves to isolate the structural color layer 20 from the cover plate 40. The thickness of the insulating layer 60 ranges from 1 μm to 3 μm. To avoid affecting display brightness, the insulating layer 60 can be made of highly transparent inorganic insulating materials such as glass or quartz. Furthermore, it is understood that since the insulating layer 60 is close to the cover plate 40, it also needs to have a certain degree of rigidity to prevent deformation. Those skilled in the art can select the specific material of the insulating layer 60 according to actual conditions; this embodiment does not impose excessive limitations in this regard.

[0053] In some embodiments, such as Figure 4 As shown, the display assembly also includes a polarizing layer 50. The polarizing layer 50 is disposed on the side of the cover plate 40 away from the structural color layer 20, to... Figure 4 Taking the orientation shown as an example, from top to bottom, the components are: light-emitting device 10, protective layer 30, structural color layer 20, insulating layer 60, cover plate 40, and polarizer layer 50. The layers can be bonded together using optical adhesives such as epoxy resin or polyurethane, or they can be deposited layer by layer during the manufacturing process to form the display component. This embodiment does not impose excessive limitations on this. The polarizer layer 50 is used to reduce the reflectivity of external light, thereby improving the clarity of the displayed image. That is, the structural color layer 20 is only used to replace the color filter to achieve color display, but the polarizer used to reduce the reflectivity of external light is still retained.

[0054] In some embodiments, such as Figure 3 As shown, the polarizer layer 50 is not present in the display component. Figure 3 Taking the orientation shown as an example, the display components, from top to bottom, consist of a light-emitting device 10, a protective layer 30, a structural color layer 20, an insulating layer 60, and a cover plate 40. Because the structural color layer 20 replaces the color filter and polarizer layer 50, the absorption of light emitted by the light-emitting device 10 can be minimized, thereby improving the display brightness of the display component. Compared to related technologies, this can increase display brightness by approximately 50%.

[0055] It is worth noting that, for example Figure 4 The polarizer layer 50 shown is compared to, for example Figure 3 When the polarizer layer 50 is not provided, the display clarity of the display component is improved, while the brightness enhancement effect is reduced. However, compared with related technologies, the display brightness can still be improved by about 10% to 20%. Furthermore, the thickness of the structural color layer 20 and the arrangement of the structural color pixels 21 can differ when the polarizer layer 50 is provided and when it is not provided. Those skilled in the art can make adaptive adjustments to achieve better display effects, and this disclosure does not impose excessive limitations on these aspects.

[0056] According to an exemplary embodiment, such as Figures 3-6 As shown, this disclosure provides a display screen, including the display components described in the above embodiments. The display screen is an OLED display screen, and the display components include a light-emitting device 10 and a structural color layer 20. The light-emitting device 10 emits light, and the structural color layer 20 has structural color pixels 21 arranged according to a preset rule. The light emitted by the light-emitting device 10 displays different colors after passing through the structural color pixels 21, achieving color display. Since the display components use the structural color layer 20 instead of a color filter to achieve color display, the structure of the display components is simplified, thereby reducing the amount of light emitted by the light-emitting device 10 being absorbed. The required display brightness can be achieved with a smaller display current, which is beneficial for extending the service life of the light-emitting device and the display components.

[0057] According to an exemplary embodiment, still referring to Figures 3-6 This disclosure provides an electronic device, which can be a mobile terminal, tablet computer, laptop computer, smartwatch, smart bracelet, wearable display device, or other device with display function and capable of displaying using an OLED screen. The electronic device includes the display component or display screen described in the above embodiments. The display component uses a structural color layer 20 to achieve color rendering, which simplifies the structure of the display component, avoids excessive absorption of light emitted by the light-emitting device 10 by the intermediate film layer, thereby improving the brightness of the display component. The current required to achieve the desired display brightness is reduced, which helps to extend the service life of the light-emitting device 10, thereby extending the service life of the display component and the display screen and reducing maintenance costs.

[0058] The following will combine Figures 7-9 The display effects achievable by the embodiments of this disclosure will be described.

[0059] Figures 7-9 This is a spectral distribution diagram of light emitted from a light-emitting device at different angles after passing through different structural color pixels. The horizontal axis represents the wavelength of the light in nm, and the vertical axis represents the transmission efficiency. 0°, 30°, 45°, and 90° represent the angles of the light emitted by the light-emitting device.

[0060] from Figure 7 As can be seen, the light emitted by the light-emitting device at 0°, 30°, 45°, and 90° passes through... Figure 5After the first structural color pixel 201, the wavelength curves of the generated light almost overlap, forming the first wavelength curve L1. The transmission efficiency of L1 is highest at point A, and the coordinates of point A are approximately (620, 0.8), which means that it can achieve a light transmittance of about 80%. The wavelength of the light with the highest transmittance is about 620nm, while the wavelength range of red light is 600nm to 700nm, with a center wavelength of about 620nm. That is, the technical solution of this embodiment can achieve a uniform effect on light from different angles, realize pure monochromatic red light, and achieve a high light transmittance, resulting in high display brightness.

[0061] from Figure 8 As can be seen, the light emitted by the light-emitting device at 0°, 30°, 45°, and 90° passes through... Figure 5 After the second structural color pixel 202 described above, the wavelength curves of the generated light almost overlap, forming a second wavelength curve L2. The point with the highest transmission efficiency of L2 is B, and the coordinates of point B are approximately (540, 0.8), which means that a light transmittance of about 80% can be achieved. The wavelength of the light with the highest transmittance is about 540nm, while the wavelength range of green light is 492nm to 577nm, with a center wavelength of about 540nm. That is, the technical solution of this embodiment can achieve a uniform effect on light from different angles, realize pure monochromatic green light, and achieve a high light transmittance, resulting in high display brightness.

[0062] from Figure 9 As can be seen, the light emitted by the light-emitting device at 0°, 30°, 45°, and 90° passes through... Figure 5 After the third structural color pixel 203 described above, the wavelength curves of the generated light almost overlap, forming a third wavelength curve L3. The transmission efficiency of L3 is highest at point C, with coordinates of approximately (460, 0.8), which means it can achieve a light transmittance of about 80%. The wavelength of the light with the highest transmittance is about 460nm, while the wavelength range of blue light is 430nm to 500nm, with a center wavelength of about 460nm. Therefore, the technical solution of this embodiment can achieve a uniform effect on light from different angles, realize pure monochromatic blue light, and achieve a high light transmittance, resulting in high display brightness.

[0063] Based on the above spectral distribution diagram, in the technical solution of this disclosure embodiment, the wavelength range of the light emitted by the display component is approximately 400nm~700nm, which can achieve coverage of red, green, and blue light. By different superposition combinations of red, green, and blue light, various colors can be displayed, enabling the display component to display the required colors. Both color rendering and display brightness are improved, resulting in better display effects, which helps to extend the service life of the display component, reduce maintenance costs, and provide a better user experience.
