Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0022] According to the first aspect of this application, referring to Figures 1 to 5This application provides a display panel 10, including a light-emitting device layer 13 and a dimming structure; the dimming structure is disposed on the light-emitting side of the light-emitting device layer 13, and the dimming structure includes a plurality of dimming lenses 20 spaced apart along a first direction. The width of each dimming lens 20 in the first direction is a first width K1. Each dimming lens 20 has a first side and a second side opposite to each other in the first direction. The distance between one dimming lens 20 on the first side and another adjacent dimming lens 20 is a first spacing, and the distance between one dimming lens 20 on the second side and another adjacent dimming lens 20 is a second spacing; wherein, at least one of the dimensions of the first width K1, the first spacing, and the second spacing corresponding to at least two dimming lenses 20 is different from each other.

[0023] By placing the dimming structure on the light-emitting side of the light-emitting device layer 13, the light path emitted from the light-emitting device layer 13 can be precisely controlled, shaped and homogenized, effectively optimizing the overall light path distribution, improving the light effect control accuracy of the display panel 10, and adapting to the demand for refined light effect in high-end display scenarios.

[0024] In the prior art, the dimming lenses 20 are all arranged in a periodic and regular pattern with equal spacing and width. The fixed periodic structure will overlap with the display pixels and the optical path diffraction period, inducing display defects such as moiré patterns and water ripples. This application breaks the inherent periodicity and regular symmetry of the dimming structure by making differentiated non-uniform designs on the width and single-sided or double-sided spacing of at least two dimming lenses 20, disrupting the fixed superposition period of optical path interference, reducing the generation of moiré patterns from the root, and optimizing the user's visual experience.

[0025] It is understood that the light-emitting device layer 13 includes an anode, a cathode, and a light-emitting material sandwiched between the anode and the cathode. The anode is a material that reflects light, and the cathode is a semi-transparent or transparent conductive material, so that light is reflected from the anode and emitted through the cathode. A microcavity resonant structure is formed between the anode and the cathode, which further improves the light extraction efficiency. The multiple dimming lenses 20 of the dimming structure are not placed between the anode and the cathode, but are independently placed on the light-emitting side of the cathode, which reduces the interference to the optical path of the microcavity and reduces the impact on the resonance enhancement effect.

[0026] It is understood that at least one of the three dimensions of the first width K1, the first spacing, and the second spacing corresponding to at least two of the dimming lenses 20 is different from each other; that is, for at least two dimming lenses 20, it includes any one or more of the following combinations: the first spacing corresponding to one dimming lens 20 is different from the first spacing corresponding to another dimming lens, the second spacing corresponding to one dimming lens 20 is different from the second spacing corresponding to another dimming lens, and the first width K1 corresponding to one dimming lens 20 is different from the first width K1 corresponding to another dimming lens.

[0027] It is understood that the first direction is the extension direction of the X-axis, the first side can be the side of the dimming lens 20 in the negative direction of the X-axis, and the second side can be the side of the dimming lens 20 in the positive direction of the X-axis.

[0028] For ease of explanation, we will take the first spacing on the first side of the dimming lens 20 as an example. The second spacing is similar and will not be described again. Figure 3 Two dimming lenses 20 are provided, labeled as first lens 201 and second lens 202 respectively. The first width K1 of first lens 201 is smaller than the first width K1 of second lens 202. The corresponding first spacing on the first side of first lens 201 is larger than the corresponding first spacing on the first side of second lens 202. The corresponding first spacing on the first side of first lens 201 is denoted by the label J1, and the corresponding first spacing on the first side of second lens 202 is denoted by the label J2. J1 is greater than J2. The first side refers to the side of dimming lens 20 pointing towards the negative X-axis direction.

[0029] Specifically, the first width K1 corresponding to the first lens 201 and the second lens 202 is different, and the first spacing corresponding to the first lens 201 and the second lens 202 is different, which further disrupts the fixed superposition period of optical path interference, weakens the generation of moiré patterns from the source, and optimizes the user's visual experience.

[0030] In some embodiments, please refer to Figure 3 For at least one of the dimming lenses 20, the first spacing and the corresponding second spacing for the same dimming lens 20 are different. For ease of explanation, Figure 3One of the dimming lenses 20 is labeled as the third lens 203. The dimensions of the first spacing and the corresponding second spacing of the third lens 203 are different. The first spacing corresponding to the third lens 203 is represented by the label J3, and the second spacing corresponding to the third lens 203 is represented by the label J4. J3 and J4 are not equal; specifically, J3 is greater than J4. The core reason for the generation of traditional moiré patterns is the periodic repetition of adjacent structures and the continuous interference superposition of optical paths. The different spacings of adjacent dimming lenses 20 on both sides of the same dimming lens 20 further break the periodic regularity of the local structure, maximally destroying the formation conditions of optical path interference, and thus achieving a more direct and precise suppression effect on moiré patterns.

[0031] In some embodiments, the first width K1 of two adjacent dimming lenses 20 is not the same. This further breaks the periodic regularity of the local structure, maximally disrupts the formation conditions of optical path interference, and reduces moiré patterns.

[0032] Specifically, the first width K1 of the dimming lens 20 can be adjusted according to parameters such as the size of the display panel 10. Optionally, the first width K1 of the dimming lens 20 is 10 micrometers to 60 micrometers, preferably 20 micrometers to 50 micrometers.

[0033] Specifically, the shape of the dimming lens 20 can be a bar-shaped cylindrical lens, a circular lens, or an elliptical lens, and its curved surface profile can be designed and adjusted according to the light field distribution requirements.

[0034] In some embodiments, please refer to Figure 3 The dimming lens 20 extends along a second direction, and the first direction intersects with the second direction; wherein, the orthographic projection of the dimming lens 20 on the light-emitting device layer 13 corresponds to the first projection, and the first pattern composed of multiple first projections is an axisymmetric pattern, and the axis of symmetry of the first pattern extends along the second direction.

[0035] It is understood that the axis of symmetry of the first pattern is represented by the symbol D1 in the figure. Based on the differential non-periodic arrangement of lenses and the suppression of moiré patterns, the axial symmetry design of the overall projection improves the symmetry and regularity of the overall layout of the dimming structure. It can balance the light emission angle and light emission brightness on both sides of the display panel 10 in the first direction, reduce the problem of overall image shift and brightness imbalance caused by the differential design of local lenses, and take into account both the elimination of moiré patterns and the image balance. The axial symmetry structure conforms to the imaging logic of the display panel 10, which can reduce the risk of light path disorder, improve the stability of the dimming structure, and facilitate mold processing and mass production, reducing the difficulty of production.

[0036] It is understandable that the second direction is the extension direction of the Y-axis, the first direction is the width direction of the entire display panel 10, i.e., the horizontal direction, and the second direction is the length direction of the entire display panel 10, i.e., the vertical direction.

[0037] In some embodiments, please refer to Figure 4 , Figure 5 The dimming lens 20 extends along a second direction, and the first direction intersects the second direction. The dimming structure includes multiple lens rows 21, which are spaced apart along the second direction. Each lens row 21 includes multiple dimming lenses 20 arranged along the first direction. Integrating the discrete dimming lenses 20 into a regular array structure of lens rows 21 allows for precise correspondence between the light-emitting areas of the light-emitting device, achieving refined dimming in specific zones. This reduces the difficulty of fabricating and aligning the dimming structure, and improves product yield.

[0038] In some embodiments, please refer to Figure 4 In the second direction, the dimming lenses 20 corresponding to two adjacent lens rows 21 are staggered, while the dimming lenses 20 corresponding to two alternate lens rows 21 are aligned. For multiple lens rows 21, an array arrangement of adjacent staggered and alternately aligned is adopted to form a non-uniform, non-periodic two-dimensional array structure. The staggered arrangement of adjacent lens rows breaks the periodic arrangement structure in the second direction, breaks the structural periodicity in the two-dimensional plane, reduces the problem of superposition interference of horizontal and vertical optical paths, and comprehensively suppresses display defects such as moiré patterns and grid patterns in the two-dimensional dimension. The alternately aligned design can retain the overall regularity of the array structure, reduce the problem of excessive optical path disorder caused by full staggered arrangement, and improve the overall balance of output brightness and angle.

[0039] Specifically, the first width K1, first spacing, and second spacing of multiple dimming lenses 20 in two adjacent lens rows 21 can be the same, and the two adjacent lens rows 21 are misaligned as a whole. For example, in two adjacent lens rows 21, one lens row 21 moves a certain distance relative to the other lens row 21 in the first direction to achieve the misalignment effect. This design can reduce the complexity of optical path modeling and simulation verification for misaligned arrangement.

[0040] Specifically, at least one of the parameters of the first width K1, the first spacing, and the second spacing of the multiple dimming lenses 20 in two adjacent lens rows 21 is different. Based on the overall misalignment of the two adjacent lens rows 21, the non-periodic characteristics are further enhanced by designing differentiated parameters.

[0041] In some embodiments, please refer to Figure 5For at least two lens rows 21, the length of the dimming lens 20 corresponding to one lens row 21 in the second direction is different from the length of the dimming lens 20 corresponding to the other lens row 21 in the second direction. The length of the dimming lens 20 in the second direction is denoted by the symbol C1. In the prior art, the length of each row of lenses is uniform, which easily leads to longitudinal fixed-period optical path interference. In different lenses, the length of the dimming lens 20 is designed differently to break the regularity of the longitudinal structure. This, combined with the differences in the spacing and width of the transverse dimming lenses 20, forms a multi-dimensional complement, suppressing moiré patterns generated in different dimensional directions in all directions.

[0042] In some embodiments, please refer to Figure 2 The display panel 10 includes a first edge B1 and a second edge B2 disposed opposite to each other in the first direction; wherein either of the dimming lenses 20 is inclined toward the first edge B1 in the thickness direction of the display panel 10, or either of the dimming lenses 20 is inclined toward the second edge B2 in the thickness direction of the display panel 10.

[0043] It is understandable that the thickness direction of the display panel 10 is the extension direction of the Z-axis. Traditional lenses all adopt a layout structure perpendicular to the display panel 10, with the light path exiting vertically and being oriented and tilted through the dimming lens 20. Figure 2 In this design, any of the dimming lenses 20 is tilted toward the second edge B2 in the thickness direction of the display panel 10, changing the light path refraction angle of the single dimming lens 20, breaking up the fixed light path period of vertical emission, and further weakening the conditions for moiré pattern generation; at the same time, for certain specific application scenarios, such as in-vehicle central control screens, it is necessary to have a certain anti-peeping effect on the driver's side to reduce the impact on the driver, while it is necessary to provide a wider viewing area on the passenger side. The tilting design can realize the directional deflection and distribution of the light path, such as the light path deflecting toward the second edge B2, thereby taking into account both safety and interactive experience.

[0044] Specifically, the tilt angle between the dimming lens 20 and the plane of the display panel 10 is between 20° and 60°. This tilt angle range is beneficial for effective deflection of the light path and can also take into account the lens processing accuracy and optical performance stability.

[0045] For details, please refer to Figure 2 The dimming lens 20 has an angle between its top surface away from the light-emitting device layer 13 and the plane where the display panel 10 is located. This can further improve the guidance of light, causing the emitted light beam to converge towards the first edge B1 or the second edge B2 of the display panel 10, thereby enhancing the brightness uniformity and viewing angle coverage of the target area.

[0046] In some embodiments, for at least two of the dimming lenses 20, each has a different tilt angle relative to the plane of the display panel 10. This differentiated tilt angle design not only enhances the non-uniformity of the light field spatial distribution but also effectively breaks the periodic symmetry of the light path, enabling the moiré suppression capability to exhibit adaptive adjustment characteristics under different viewing angles.

[0047] In some embodiments, please refer to Figure 1 , Figure 2 The display panel 10 further includes a substrate 11, a blocking portion 19, and an encapsulation filling layer 30. The light-emitting device layer 13 and the blocking portion 19 are both disposed on the substrate 11. The blocking portion 19 is disposed along the periphery of the display panel 10 and forms a blocking cavity with the substrate 11. The light-emitting device layer 13 and the encapsulation filling layer 30 are both disposed within the blocking cavity. The encapsulation filling layer 30 is disposed on the side of the light-emitting device layer 13 away from the substrate 11 and covers the light-emitting surface of the light-emitting device layer 13. The encapsulation filling layer 30 includes a first layer 31 and a second layer 32. The second layer 32 is disposed on the side of the first layer 31 away from the light-emitting device layer 13. The refractive index of the first layer 31 is different from that of the second layer 32. The surface of the first layer 31 facing the second layer 32 is provided with a plurality of microstructures, which correspond to the dimming lens 20.

[0048] The enclosed enclosure 19 forms a closed enclosure cavity, which can provide physical protection for the internal light-emitting device layer 13 and the encapsulation filling layer 30, isolate external dust, moisture and mechanical impact, protect the structure of the light-emitting device, and improve the service life and working stability of the display panel 10. The encapsulation filling layer 30 fully covers the light-emitting surface of the light-emitting device, which can encapsulate and protect the light-emitting device layer 13 as a whole. The filling layer can flatten the light-emitting surface, weaken the light path scattering caused by the micro-uneven structure of the light-emitting device surface, and initially optimize the uniformity of light output.

[0049] Abandoning the traditional independent attached dimming layer structure, this application integrates the dimming structure into the encapsulation filling layer 30. The dimming structure is formed by the microstructure of the double-layer interface of the first layer 31 and the second layer 32 of the encapsulation filling layer 30. It can be understood that the microstructure is the dimming lens 20, so only the dimming lens 20 is marked in the figure.

[0050] Specifically, by utilizing the dual-layer structure of the first layer 31 and the second layer 32 of the encapsulation filling layer 30, a continuous optical modulation interface is formed at the interlayer interface through the refractive index difference between the two media, which can adjust the emitted light. At the same time, by setting microstructures at the interface of the first layer 31 facing the second layer 32, multiple microstructures are correspondingly composed of a dimming lens 20. The dimming lens 20 formed by the microstructure completes the fine-tuning of the optical path and the control of scattering, breaking the inherent periodicity of the traditional regular optical structure and suppressing display defects such as moiré patterns and grid patterns from the root. At the same time, this integrated structure combines the dimming function and the encapsulation protection function into one, reducing the number of stacked layers of the display panel 10 and achieving a thinner and lighter overall device. Moreover, the microstructure is integrally formed during the formation of the encapsulation filling layer 30, with tight interlayer bonding and strong structural integrity, which can effectively eliminate process defects such as bubbles, delamination, misalignment, and structural periodic errors caused by traditional multi-layer bonding processes, and improve the product structural stability and mass production yield.

[0051] Specifically, the refractive index difference between the first layer 31 and the second layer 32 can be set according to actual optical control requirements. The refractive index of the first layer 31 can be greater than that of the second layer 32 to achieve light divergence; the refractive index of the first layer 31 can be less than that of the second layer 32 to achieve light convergence; the difference in refractive index between the two can also be adaptively designed according to the requirements of beam angle, uniformity and contrast in actual application scenarios.

[0052] Specifically, the refractive index of the first layer 31 can be greater than that of the second layer 32, with the difference between the refractive indices of the first layer 31 and the second layer 32 being 0.2 to 0.6; the refractive index of the first layer 31 is 1.3 to 2.1, and the refractive index of the second layer 32 is 1.1 to 1.5. This range of refractive index difference has been experimentally verified to balance optical modulation efficiency and material processing feasibility.

[0053] In some embodiments, the first layer 31 includes a photosensitive material. It is understood that the first layer 31 and the second layer 32 of the encapsulation filling layer 30 may include materials such as acrylic resin and polyacrylic resin. These resin materials possess high optical transmittance, good optical uniformity, excellent formability, and low cost. They can reduce the light absorption and light path scattering loss of the encapsulation filling layer 30 itself, improve light extraction efficiency and image transparency, and at the same time, they have strong material stability, are not prone to aging and yellowing, and can ensure the optical consistency of the display panel 10 for long-term use. The first layer 31 also includes a photosensitive material. Using acrylic resin and polyacrylic resin as substrates, combined with the photosensitive material in the first layer 31, its core function is to adapt to the photolithography exposure process. Through precise exposure and development processes, the required microstructure can be precisely fabricated at the interface between the first layer 31 and the second layer 32, thereby stably forming the dimming lens 20. Compared to the limitations of conventional non-photosensitive materials in precisely fabricating micro-lens structures, this method leverages the photosensitive molding characteristics of photosensitive materials to achieve precise integrated molding of microstructures and dimming lenses 20. The resulting structure boasts high morphological accuracy and good consistency, accurately matching the design requirements of differentiated lens parameters. This ensures the non-periodic arrangement of the dimming structure, stably achieving the core functions of suppressing moiré patterns and optimizing optical path uniformity, thereby improving product dimensional accuracy and production yield.

[0054] Specifically, the photosensitive material can be selected from photosensitive materials such as epoxy photosensitive resin and polyurethane photosensitive resin that are compatible with the encapsulation process of the display panel 10.

[0055] In some embodiments, the microstructure of the first layer 31 can also be formed by imprinting.

[0056] In some embodiments, please refer to Figure 1 , Figure 2 The display panel 10 further includes an array substrate 12, which is disposed between the substrate 11 and the light-emitting device layer 13.

[0057] For details, please refer to Figure 1 , Figure 2 The display panel 10 further includes a planar encapsulation layer 14 disposed between the light-emitting device layer 13 and the encapsulation filling layer 30. The planar encapsulation layer 14 may include a thin film encapsulation layer 15 and a planarization layer 16. The thin film encapsulation layer 15 may be an inorganic-organic-inorganic stacked structure, which has both high water and oxygen barrier properties and surface flatness. The planarization layer 16 covers the thin film encapsulation layer 15 and is used to further eliminate the micro-undulations on the surface of the thin film encapsulation layer 15.

[0058] For details, please refer to Figure 1 , Figure 2The display panel 10 also includes a color filter substrate 17, which is disposed on the side of the encapsulation filling layer 30 and the blocking portion 19 away from the light-emitting device layer 13. The color filter substrate 17 is provided with a black matrix, a color filter unit and an optical layer 18. The optical layer 18 can be an AR (Anti-Reflection Coating) layer to suppress ambient light reflection and improve display contrast and visual transparency.
