[0003] However, in the related art, the self-luminous display panel has the problem of poor brightness uniformity of sub-pixels of each color. Summary of the Invention

[0004] The present disclosure aims to provide a light regulating structure, a method for manufacturing the light regulating structure, and a display panel, for improving the brightness uniformity of sub-pixels of various colors of the display panel.

[0005] In order to achieve the above objectives, the present disclosure provides the following technical solutions:

[0006] In one aspect, a light-regulating structure is provided. The light-regulating structure includes a base layer, multiple filter sections, a filling section, and a light-shielding pattern. The multiple filter sections are located on one side of the base layer. The multiple filter sections are spaced apart. The filling section is located within the gaps between the multiple filter sections and around the entirety of the multiple filter sections. Furthermore, the filling section covers an edge portion of at least one filter section on a side facing away from the base layer. The light-shielding pattern is located on the side of the filling section facing away from the base layer.

The filtering portion includes a light incident surface and a first inclined surface. The light incident surface contacts the substrate layer. One end of the first inclined surface is connected to the light incident surface, and the other end extends away from the light incident surface. A first angle is formed between the first inclined surface and the light incident surface, and the first angle is an obtuse angle.

[0008] In some embodiments, an orthographic projection of the first inclined surface on the base layer falls within a range of an orthographic projection of the light-shielding pattern on the base layer.

[0009] In some embodiments, the light-shielding pattern includes a main body and an annular portion. The main body has a plurality of first openings. The annular portion is located within the first openings. A light-transmitting groove is defined between the annular portion and the main body. A second opening is formed within the annular portion, exposing the light-filtering portion. At least a portion of the orthographic projection of the first inclined surface on the base layer is located between the orthographic projection of the main body and the orthographic projection of the annular portion on the base layer.

[0010] In some embodiments, the light-transmitting groove has a first port and a second port, the second port being closer to the base layer than the first port. The orthographic projection of the edge of the first port on the base layer encloses a first area, and the orthographic projection of the edge of the second port on the base layer falls within the first area.

The orthographic projection of the color filter film on the base layer at least partially overlaps with the orthographic projection of the light-shielding pattern on the base layer.

[0014] In some embodiments, the light-modulating structure further includes a covering layer. The covering layer is located on a side of the plurality of filter portions, the filling portion, and the light-shielding pattern that is away from the base layer. The covering layer covers the plurality of filter portions, the filling portion, and the light-shielding pattern, and the refractive index of the covering layer is greater than or equal to the refractive index of the filter portions.

[0015] In another aspect, a method for preparing a light-regulating structure is provided. The method includes forming a plurality of filter sections on one side of a substrate layer. The plurality of filter sections are spaced apart. A filling section is formed. The filling section is located within the gaps between the plurality of filter sections and around the plurality of filter sections as a whole. The filling section also covers an edge portion of at least one filter section on a side facing away from the substrate layer. A light-shielding pattern is formed. The light-shielding pattern is located on the surface of the filling section facing away from the substrate layer.

[0016] In another aspect, a display panel is provided. The display panel includes a display substrate and the above-described light modulation structure. The light modulation structure is located on the display side of the display substrate.

[0017] In some embodiments, the display substrate includes an encapsulation layer, which is multiplexed as a base layer of the light modulation structure.

[0018] In some embodiments, the display substrate further comprises a substrate, a circuit structure layer, a planar layer, a light-emitting structure layer, and an encapsulation layer.

The light transmittance of the planar layer is less than or equal to 10%. The light-emitting structure layer is located on the side of the planar layer away from the circuit structure layer. The light-emitting structure layer comprises a light-emitting layer. The light-emitting layer comprises a plurality of effective light-emitting portions, wherein the orthographic projection of an effective light-emitting portion on the substrate layer falls within the range of the orthographic projection of a filter portion on the substrate layer. The encapsulation layer is located on the side of the light-emitting structure layer away from the planar layer.

[0019] In some embodiments, the display substrate further comprises a substrate, a circuit structure layer, a planar layer, a light-emitting structure layer, and an encapsulation layer. The circuit structure layer is located on one side of the substrate. The planar layer is located on the side of the circuit structure layer away from the substrate. The light-emitting structure layer is located on the side of the planar layer away from the circuit structure layer.

The pixel defining layer has a third opening, and the light-emitting layer comprises a plurality of effective light-emitting portions, one effective light-emitting portion is located within one of the third openings, and the orthographic projection of one of the effective light-emitting portions on the base layer falls within the range of the orthographic projection of one of the filter portions on the base layer. The transmittance of the pixel defining layer is less than or equal to 10%. The encapsulation layer is located on the side of the light-emitting structure layer away from the planar layer.

[0020] The light regulating structure, the method for preparing the light regulating structure, and the display panel provided by the present disclosure have the following beneficial effects:

[0021] The light-regulating structure provided by the embodiments of the present disclosure is configured such that a filling portion is provided to cover the edge portion of the surface of the filter portion on the side away from the base layer, that is, the filling portion is provided to overlap the edge portion of the surface of the filter portion on the side away from the base layer, so that the filling portion can be filled in the gaps between the multiple filter portions, thereby avoiding the formation of gaps between the filling portion and the filter portion, which causes reflected light to be emitted through the gaps between the filling portion and the filter portion, thereby improving the reliability of the light-regulating structure.

[0022] The shading pattern is arranged on the side of the filling part away from the base layer, which not only blocks the reflected light, but also avoids the influence of the shading pattern on the contact between the filter part and the base layer, so that the surface of the filter part close to the base layer (that is, the light incident surface) can be fitted with the base layer, thereby improving the flatness of the surface of the filter part away from the base layer (that is, the light emitting surface), so that the filter part can be a flat or nearly flat film layer structure.

[0023] In this way, the refraction effect of light on the light-emitting surface can be reduced, and the light can be prevented from gathering in the central area of ​​the light-emitting surface, so that the brightness of the central area of ​​the light-emitting surface and the brightness of the edge area can be the same or approximately the same, thereby improving the brightness uniformity of the filter part, that is, improving the brightness uniformity of each color sub-pixel of the display panel, thereby improving the display effect of the display panel.

[0024] The method for preparing the light regulating structure provided by the embodiment of the present disclosure is used to prepare the above-mentioned light regulating structure, and therefore has all the above-mentioned beneficial effects, which will not be described in detail here.

[0025] The display panel provided by the embodiment of the present disclosure includes the above-mentioned light adjustment structure, and thus has all the above-mentioned beneficial effects, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0054] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0055] When describing some embodiments, the term "connected" and its derivatives may be used. For example, when describing some embodiments, the term "connected" may be used to indicate that two or more components are in direct physical contact with each other.

[0060] Figure 1 is a structural diagram of a display panel 200 according to some embodiments.

[0061] like Figure 1 As shown, an embodiment of the present disclosure provides a display panel 200 for displaying images. It is understood that the display panel 200 can display static images, such as pictures or photos, or dynamic images, such as videos or game screens.

[0062] In some examples, the display panel 200 is any one of an organic light-emitting diode display (full name: Organic Light-Emitting Diode, English abbreviation: OLED) or a quantum dot light-emitting diode display (Quantum dot Light Emitting Diodes, abbreviated as QLED).

[0063] In some examples, the display panel 200 is square, circular, oval, or other irregular shapes to improve the applicability of the display panel 200. It is understandable that the embodiments of the present disclosure do not further limit the shape of the display panel 200. The structure of the display panel 200 is described below by way of example.

[0064] In some embodiments, as Figure 1 As shown, the display panel 200 includes a display substrate 210 and a light adjustment structure 100. The display substrate 210 has a display side, and light is emitted through the display side of the display substrate 210.

[0065] In some examples, the display substrate 210 is any one of an OLED display substrate, a Mini LED (English full name: Mini Light Emitting Diode, Chinese name: sub-millimeter light-emitting diode) display substrate, or a Micro LED (English full name: Micro Light Emitting Diode, Chinese name: micro light-emitting diode) display substrate.

[0066] It can be understood that a Mini LED display substrate, that is, an LED chip with a size greater than or equal to 50μm and less than 300μm, and a distance between LED chips ranging from 0.5mm to 1.2mm. A Micro LED display substrate, that is, an LED chip with a size less than 50μm and a distance between LED chips less than 0.05mm.

[0067] The light regulating structure 100 is located on the display side of the display substrate 210, and the light emitted by the display substrate 210 can illuminate the light regulating structure 100. The light regulating structure 100 is used to filter the light and perform other processing so that the display panel 200 can realize the image display function.

[0068] In the embodiment of the present disclosure, the structure of the display substrate 210 is described by taking the display substrate 210 as an OLED display substrate as an example.

[0069] Figure 2 FIG. 2 is a structural diagram of a display substrate 210 according to some embodiments.

[0070] like Figure 2 As shown, the display substrate 210 includes a substrate 212 , a circuit structure layer 213 , a planar layer 214 , a light emitting structure layer 215 and an encapsulation layer 211 .

[0071] In some examples, the substrate 212 is a flexible material, so that the display substrate 210 can be bent, thereby enabling the display panel 200 to achieve a curved display. In other examples, the substrate 212 is a rigid material.

[0072] For example, the material of the substrate 212 can be any one of polyimide (English full name: Polyimide, English abbreviation: PI), polycarbonate (English full name: polycarbonate, English abbreviation: PC) or polyvinyl chloride (English full name: polyvinylchloride, English abbreviation: PVC).

[0073] The circuit structure layer 213 is located on one side of the substrate 212 . In some examples, a plurality of pixel driving circuits are disposed in the circuit structure layer 213 . The plurality of pixel driving circuits are electrically connected to the light emitting structure layer 215 to drive the light emitting structure layer 215 to emit light.

[0074] In some examples, each pixel driving circuit includes a thin film transistor (TFT) and a capacitor to achieve driving of the light emitting structure layer 215 .

[0075] The planar layer 214 is located on the side of the circuit structure layer 213 away from the substrate 212. It can be understood that the surface of the planar layer 214 away from the circuit structure layer 213 is a flat surface or a nearly flat surface. In some examples, the planar layer 214 is made of an organic material.

[0076] Figure 3 is a structural diagram of the light emitting structure layer 215 according to some embodiments.

[0077] like Figure 2 As shown, the light emitting structure layer 215 is located on the side of the flat layer 214 away from the circuit structure layer 213. Figure 3 , the light emitting structure layer 215 is illustrated by way of example.

[0078] In some embodiments, as Figure 3 As shown, the light emitting structure layer 215 includes a light emitting layer 2151. The light emitting layer 2151 includes a plurality of effective light emitting portions 2152. The plurality of effective light emitting portions 2152 can be arranged at intervals. It can be understood that the effective light emitting portions 2152 are used to emit light.

[0079] In some examples, the light emitting layer 2151 may include only a plurality of effective light emitting portions 2152, such as Figure 3 In other examples, the light-emitting layer 2151 may also be a whole-layer structure, that is, a portion of the light-emitting layer 2152 is a plurality of effective light-emitting portions 2152 , and another portion connects the plurality of effective light-emitting portions 2152 together to form a whole-layer structure.

[0080] In some examples, the effective light-emitting portion 2152 includes an electroluminescent material. Electroluminescence refers to the phenomenon in which an organic semiconductor material emits light through carrier injection, transport, and the combination of electrons and holes to form excitons under the influence of an electric field, followed by radiative recombination.

[0081] In some examples, the shape of the effective light-emitting portion 2152 may be a square, a circle, or an irregular polygon, etc. The shapes of the multiple effective light-emitting portions 2152 may be the same or different.

[0082] In some examples, all of the effective light-emitting portions 2152 are configured to emit white light. In other examples, some of the effective light-emitting portions 2152 are configured to emit red light, some are configured to emit green light, and some are configured to emit blue light.

[0083] For example, different electroluminescent materials can be selected so that the effective light-emitting portion 2152 can emit light of different colors.

[0084] It can be understood that the number of the effective light-emitting portions 2152 emitting red light, the effective light-emitting portions 2152 emitting green light, and the effective light-emitting portions 2152 emitting blue light can be the same or different.

[0085] In some examples, the effective light-emitting portions 2152 emitting red light, the effective light-emitting portions 2152 emitting green light, and the effective light-emitting portions 2152 emitting blue light can be arranged in a mixed array. In this way, by controlling the light intensity of the different effective light-emitting portions 2152, different intensities of red light, green light, and blue light can be obtained. By mixing the red light, green light, and blue light of different intensities, the display panel 200 can display a color image.

[0086] In some examples, such as Figure 3 As shown, the light emitting structure layer 215 further includes an anode layer AND and a cathode layer CTD. The anode layer AND is located on the side of the planar layer 214 away from the circuit structure layer 213. The multiple effective light emitting portions 2152 are located on the side of the anode layer AND away from the planar layer 214. The cathode layer CTD is located on the side of the multiple effective light emitting portions 2152 away from the anode layer AND.

[0087] As can be seen from the above, the multiple pixel driving circuits in the circuit structure layer 213 can drive the light-emitting structure layer 215 to emit light. In some examples, one pixel driving circuit is electrically connected to one effective light-emitting portion 2152 through the anode layer AND, so that each pixel driving circuit can provide a driving current to each effective light-emitting portion 2152 through the anode layer AND. In other words, the multiple effective light-emitting portions 2152 can emit light independently, reducing mutual interference between the multiple effective light-emitting portions 2152 and improving the display effect of the display substrate 210.

[0088] It can be understood that by adjusting the magnitude of the driving current provided by the pixel driving circuit to the effective light-emitting portion 2152 , the light-emitting brightness of the effective light-emitting portion 2152 can be adjusted.

[0089] In some examples, the anode layer AND is a metal material, such as copper or silver. The cathode layer CTD is a transparent material, such as transparent indium tin oxide (ITO) or transparent indium zinc oxide (IZO), so that light emitted by the effective light-emitting portion 2152 can be emitted through the cathode layer CTD. In this case, the display substrate 210 is a top-emitting display substrate.

[0090] In other examples, the anode layer AND is a transparent material, such as ITO or IZO, and the cathode layer CTD is a metal material, such as copper or silver, so that the light emitted by the effective light-emitting portion 2152 can be emitted through the anode layer AND, that is, the display substrate 210 is a bottom-emitting display substrate.

[0091] In some other examples, the anode layer AND and the cathode layer CTD are both transparent materials, such as ITO or IZO, so that the light emitted by the effective light-emitting portion 2152 can be emitted through the anode layer AND and the cathode layer CTD, that is, the display substrate 210 is a double-sided light-emitting display substrate.

[0092] In some examples, at least one of a hole injection layer (HIL), a hole transport layer (HTL), and an electron blocking layer (EBL) is disposed between the anode layer AND and the effective light-emitting portion 2152 along the direction from the anode layer AND to the effective light-emitting portion 2152. At least one of an electron injection layer (EIL), an electron transport layer (ETL), and a hole blocking layer (HBL) is disposed between the cathode layer CTD and the effective light-emitting portion 2152 along the direction from the cathode layer CTD to the effective light-emitting portion 2152 to improve the light-emitting reliability of the effective light-emitting portion 2152.

[0093] Figure 4 FIG is a structural diagram of the light emitting structure layer 215 according to some other embodiments. Figure 4 , the light emitting structure layer 215 is further described with examples.

[0094] As can be seen from the above, the plurality of effective light emitting portions 2152 are arranged at intervals between the anode layer AND and the cathode layer CTD. Figure 4 As shown, the light emitting structure layer 215 further includes a pixel defining layer 2153 (full name: PixelDefiningLayer, English abbreviation: PDL). The pixel defining layer 2153 is located between the anode layer AND and the cathode layer CTD. In some examples, the pixel defining layer 2153 is an organic material.

[0095] like Figure 4 As shown, the pixel defining layer 2153 has third openings 2154. It can be understood that the number of the third openings 2154 is the same as the number of the effective light emitting portions 2152. Figure 3 As shown, an effective light-emitting portion 2152 is located in a third opening 2154 .

[0096] It can be understood that by arranging an effective light-emitting portion 2152 within a third opening 2154, the pixel defining layer 2153 can limit the effective light-emitting portion 2152, preventing the effective light-emitting portion 2152 from shifting. In addition, the pixel defining layer 2153 can also separate multiple effective light-emitting portions 2152, further reducing mutual interference between the multiple effective light-emitting portions 2152 and improving the display effect of the display substrate 210.

[0097] like Figure 2 As shown, the encapsulation layer 211 of the display substrate 210 is located on a side of the light emitting structure layer 215 away from the flat layer 214. It can be understood that the encapsulation layer 211 is used to encapsulate and protect the light emitting structure layer 215 to extend the service life of the light emitting structure layer 215.

[0098] In some examples, the encapsulation layer 211 is an organic material. In other examples, the encapsulation layer 211 includes two inorganic film layers and one organic film layer, and the organic film layer is located between the two inorganic film layers that are spaced apart.

[0099] As can be seen from the above, at least one of the anode layer AND and the cathode layer CTD is made of a transparent material, allowing light emitted by the effective light-emitting portion 2152 to pass through at least one of the anode layer AND and the cathode layer CTD and be emitted externally. Some embodiments of the present disclosure are described as follows, using an example in which the anode layer AND is made of a metal material, the cathode layer CTD is made of a transparent material, and the encapsulation layer 211 is also made of a transparent material, with light emitted by the effective light-emitting portion 2152 being emitted externally through the cathode layer CTD and the encapsulation layer 211.

[0100] It can be understood that the light emitted by the effective light emitting portion 2152 is emitted through the cathode layer CTD and the encapsulation layer 211, so that the side of the encapsulation layer 211 away from the substrate 212 is the display side of the display substrate 210. The light adjustment structure 100 is located on the display side of the display substrate 210, as shown in FIG. Figure 1 As shown, the light regulating structure 100 is located on the side of the packaging layer 211 away from the substrate 212 .

[0101] Figure 5 is a structural diagram of a display panel 200 according to some other embodiments. Figure 6 FIG is a structural diagram of a display panel 200 according to some other embodiments. Figure 5 and Figure 6 , the light adjustment structure 100 is illustrated by way of example.

[0102] In some embodiments, as Figure 5 As shown, the light-regulating structure 100 includes a base layer 110 and a plurality of light filtering portions 120 .

[0103] It is understood that the base layer 110 is a transparent material to prevent the base layer 110 from blocking the light emitted by the effective light emitting portion 2152, so that the light can be irradiated to the light regulating structure 100. For example, the base layer 110 can be a transparent organic material.

[0104] In some embodiments, as Figure 5 As shown, the encapsulation layer 211 is reused as the base layer 110 of the light regulating structure 100, that is, the encapsulation layer 211 of the display substrate 210 and the base layer 110 of the light regulating structure 100 are the same film layer structure, which simplifies the structure of the display panel 200 and reduces the cost of the display panel 200.

[0105] In some examples, the structure in which the encapsulation layer 211 of the display substrate 210 can be reused as the base layer 110 of the light modulation structure 100 is called a color filter on encapsulation structure (full name: Color filter on Encapsulation, English abbreviation: COE).

[0106] In other embodiments, Figure 6 As shown, the base layer 110 and the encapsulation layer 211 may also be different film layer structures, and the base layer 110 is located on a side of the encapsulation layer 211 away from the substrate 212 .

[0107] It is understood that the filter portion 120 is used to filter light. In some examples, the filter portion 120 is made of an organic material.

[0108] As can be seen from the above, the light-emitting layer 2151 includes a plurality of effective light-emitting portions 2152. It can be understood that the number of the effective light-emitting portions 2152 is the same as the number of the filter portions 120. Figure 5As shown, the orthographic projection of an effective light-emitting portion 2152 on the base layer 110 falls within the range of the orthographic projection of a filter portion 120 on the base layer 110, that is, the setting position of an effective light-emitting portion 2152 corresponds to the setting position of a filter portion 120, and the area of ​​the orthographic projection of an effective light-emitting portion 2152 on the base layer 110 is smaller than the area of ​​the orthographic projection of a filter portion 120 on the base layer 110, so that the light emitted by the effective light-emitting portion 2152 can only be emitted after being filtered by the filter portion 120, thereby avoiding the light being directly emitted without being filtered by the filter portion 120, thereby improving the display effect of the display panel 200.

[0109] In some examples, one effective light emitting portion 2152 and one filter portion 120 corresponding to the effective light emitting portion 2152 may be referred to as a sub-pixel. It is understood that the display panel 200 includes a plurality of sub-pixels of different colors.

[0110] In some examples, a portion of the multiple filter sections 120 are used to filter red light, another portion of the filter sections 120 are used to filter green light, and another portion of the filter sections 120 are used to filter blue light, that is, red light, filtered light and blue light can be emitted from the light regulating structure 100 respectively.

[0111] In some examples, when a portion of the multiple effective light-emitting portions 2152 is configured to emit red light, another portion is configured to emit green light, and yet another portion is configured to emit blue light, the effective light-emitting portions 2152 emitting red light can be positioned to correspond to the position of the filter portion 120 that filters red light. The effective light-emitting portions 2152 emitting green light can be positioned to correspond to the position of the filter portion 120 that filters green light. The effective light-emitting portions 2152 emitting blue light can be positioned to correspond to the position of the filter portion 120 that filters blue light. In this way, red light, green light, and blue light can each be emitted through the corresponding filter portion 120.

[0112] like Figure 1 As shown, the light-modulating structure 100 further includes a light-shielding pattern 140. As will be appreciated, the light-shielding pattern 140 is used to block light. In some examples, the material of the light-shielding pattern 140 can be a black organic material to provide a light-shielding effect. For example, carbon powder and graphite can be added to a transparent organic material to form a black organic material.

[0113] Refer to the following Figure 1 , the positional relationship among the base layer 110, the plurality of filter portions 120, and the light-shielding pattern 140 in some implementations is illustrated.

[0114] In some implementations, such as Figure 1As shown, the light shielding pattern 140 is located on a side of the base layer 110 away from the substrate 212. The light shielding pattern 140 is provided with a plurality of through holes, which penetrate the light shielding pattern 140 from the base layer 110. One filter portion 120 is located in one through hole, so that multiple filter portions 120 can be arranged at intervals.

[0115] It is understandable that a portion of the light emitted by the effective light-emitting portion 2152 can be reflected by the circuit structure layer 213 or the anode layer AND and irradiate between two adjacent filter portions 120. Therefore, by arranging one filter portion 120 within one through-hole, the light-shielding pattern 140 can be located between two adjacent filter portions 120, thereby shielding the reflected light irradiating between the two adjacent filter portions 120.

[0116] For example, Figure 1 As shown in the middle light a, when a portion of the light emitted by the effective light-emitting portion 2152 is reflected by the circuit structure layer 213 and irradiates between two adjacent filter portions 120, it can be blocked by the shading pattern 140, thereby reducing the intensity of the reflected light emitted between the two adjacent filter portions 120, thereby reducing the impact of the reflected light on the light emitted through the filter portion 120, and improving the display effect of the display panel 200.

[0117] In some implementations, such as Figure 1 As shown, the edge of the filter portion 120 close to the surface of one side of the base layer 110 overlaps with the edge of the surface of the shading pattern 140 away from the base layer 110, avoiding the formation of a gap between the shading pattern 140 and the filter portion 120, causing the reflected light to be emitted through the gap between the shading pattern 140 and the filter portion 120, further improving the shielding effect of the shading pattern 140 on the reflected light.

[0118] Compared to using polarizers to block reflected light, using the light-modulating structure 100 to block reflected light can achieve a high color gamut, low power consumption, and greater controllability. Furthermore, the light-modulating structure 100 facilitates integration with other film structures (such as in-screen antennas, under-screen cameras, touch panels, or under-screen fingerprint sensors), thus reducing the thickness of the display panel 200.

[0119] Figure 7 is a structural diagram of the filter unit 120 according to some embodiments. Figure 8 1 is a structural diagram of the filter portion 120 and the light shielding pattern 140 according to some embodiments.

[0120] The inventors of the present disclosure have discovered that the above implementation method has the following technical problems.

[0121] Setting the edge of the filter portion 120 close to the substrate layer 110 to overlap the edge of the light shielding pattern 140 away from the substrate layer 110 will make the edge of the filter portion 120 close to the substrate layer 110 unable to fit with the substrate layer 110. Figure 7 As shown, the surface of the filter portion 120 away from the base layer 110 is bent toward the base layer 110 .

[0122] In some examples, such as Figure 8 As shown, the surface of the filter portion 120 close to the base layer 110 can be called the light incident surface 122, and the surface of the filter portion 120 away from the base layer 110 can be called the light emitting surface 126. It can be understood that the light emitted by the effective light-emitting portion 2152 is irradiated to the filter portion 120 through the light incident surface 122 and emitted through the light emitting surface 126.

[0123] like Figure 8 As shown in the direction of the middle arrow, when light is irradiated to the light emitting surface 126 through the light incident surface 122 of the filter portion 120 , the light emitting surface 126 is bent toward the direction close to the base layer 110 , causing the light to be refracted at the light emitting surface 126 and thus gathered in the central area of ​​the light emitting surface 126 .

[0124] In this way, the brightness of the central area of ​​the light emitting surface 126 will be greater than the brightness of the edge area of ​​the light emitting surface 126, resulting in uneven brightness of the filter portion 120, that is, making the brightness of each color sub-pixel of the display panel 200 uneven, affecting the display effect of the display panel 200.

[0125] Figure 9 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure. Figure 10 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure. Figure 11 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure. Figure 12 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure.

[0126] In order to solve the above technical problems, the light adjustment structure 100 provided in the embodiment of the present disclosure includes a base layer 110 , a plurality of filter portions 120 , a filling portion 130 and a light shielding pattern 140 .

[0127] It can be understood that the above-mentioned embodiments of the present disclosure have provided examples of the functions and materials of the base layer 110, the filter portion 120 and the shading pattern 140, and have also provided examples of the positional relationship between the filter portion 120 and the effective light emitting 2152, and the relationship between the base layer 110 and the encapsulation layer 211, which will not be repeated here.

[0128] Refer to the following Figures 9 to 12 , the positional relationship among the base layer 110, the plurality of filter portions 120, the filling portion 130 and the light shielding pattern 140 in some embodiments of the present disclosure is illustrated by way of example.

[0129] like Figure 5 As shown, multiple filter sections 120 are located on one side of the base layer 110. It can be understood that the multiple filter sections 120 are located on the side of the base layer 110 away from the substrate 212. The multiple filter sections 120 are spaced apart so that there are gaps between the multiple filter sections 120. In some examples, the spacing between the multiple filter sections 120 can be the same or different.

[0130] In some examples, such as Figure 9 As shown, the filter section 120 includes a red filter section 120R, a green filter section 120G, and a blue filter section 120B. The red filter section 120R, the green filter section 120G, and the blue filter section 120B are arranged in a mixed array, so that the display panel 200 can display color images. It can be understood that the embodiments of the present disclosure do not further limit the arrangement of the red filter section 120R, the green filter section 120G, and the blue filter section 120B.

[0131] like Figure 10 As shown, the filling portion 130 is located in the gaps between the plurality of filter portions 120. Figure 9 As shown, the filling portion 130 is also located around the entirety of the plurality of filter portions 120. It can be understood that the entirety of the plurality of filter portions 120 is to regard the plurality of filter portions 120 as a whole, and the filter portion 120 closest to the outermost side of the plurality of filter portions 120 as the edge of the entirety. The filling portion 130 is located around the entirety of the plurality of filter portions 120, as shown in FIG. Figure 9 As shown, the filling portion 130 can surround the entire edge of the filter portion 120 .

[0132] It is understood that the filling portion 130 is positioned within the gaps between the plurality of filter portions 120 and around the entirety of the plurality of filter portions 120, so that the filling portion 130 can surround any of the filter portions 120. In some examples, the filling portion 130 is in contact with the outer surface of each filter portion 120, so that the filling portion 130 can fill the gaps between the plurality of filter portions 120.

[0133] like Figure 10 As shown, the filling portion 130 covers the edge portion of at least one filter portion 120 away from the base layer 110 , that is, the filling portion 130 can overlap the edge portion of the filter portion 120 away from the base layer 110 .

[0134] It is understood that the edge portion of the filter portion 120 away from the substrate layer 110 is also the edge portion of the light-emitting surface 126. The embodiments of the present disclosure do not further limit the shape and area of ​​the "edge portion" of the light-emitting surface 126. The shape and area of ​​the edge portions of different light-emitting surfaces 126 can be the same or different.

[0135] In some examples, the filling portion 130 covers an edge portion of a surface of any filter portion 120 away from the base layer 110 .

[0136] In some examples, such as Figure 10 As shown, the thickness H1 of the filling portion 130 is greater than the thickness H2 of the filter portion 120, allowing the filling portion 130 to overlap the edge of the filter portion 120 on the side away from the base layer 110. Furthermore, due to the greater thickness H1 of the filling portion 130, even if the filling portion 130 overlaps the edge of the filter portion 120 on the side away from the base layer 110, the flatness of the surface of the filling portion 130 on the side away from the base layer 110 is minimally affected. This allows the surface of the filling portion 130 on the side away from the base layer 110 to be planar or substantially planar, i.e., the filling portion 130 to have a flat or substantially flat film structure.

[0137] It can be understood that by setting the filling part 130 to cover the edge portion of the surface of the filter part 120 on the side away from the base layer 110, that is, setting the filling part 130 to overlap the edge portion of the surface of the filter part 120 on the side away from the base layer 110, the filling part 130 can be filled in the gap between the multiple filter parts 120, avoiding the formation of gaps between the filling part 130 and the filter part 120, causing the reflected light to be emitted through the gap between the filling part 130 and the filter part 120, thereby improving the reliability of the light adjustment structure 100.

[0138] In some examples, the filling portion 130 is a transparent organic material, for example, transparent acrylic, phenolic resin, or epoxy resin.

[0139] like Figure 11 As shown, the light shielding pattern 140 is located on a side of the filling portion 130 away from the base layer 110 . The light shielding pattern 140 can block (eg, absorb) reflected light.

[0140] For example, Figure 11 and Figure 12 As shown, the light shielding pattern 140 covers the surface of the filling portion 130 away from the base layer 110 .

[0141] Here, it should be noted that the light shielding pattern 140 may be directly disposed on the surface of the filling portion 130 away from the base layer 110 , or other film structures may be disposed between the light shielding pattern 140 and the filling portion 130 .

[0142] For example, Figure 11 As shown in the middle light d, after the reflected light is irradiated to the filling portion 130 through the gaps between the multiple filter portions 120, it can be blocked by the shading pattern 140, thereby reducing the intensity of the reflected light emitted through the gaps between the multiple filter portions 120, reducing the impact of the reflected light on the light emitted through the filter portion 120, and improving the display effect of the display panel 200.

[0143] It can be understood that the filling portion 130 is a flat or approximately flat film structure, and the shading pattern 140 is located on the surface of the filling portion 130 away from the base layer 110, so that the shading pattern 140 can also be a flat or approximately flat film structure.

[0144] It can be understood that the shading pattern 140 is arranged on the side of the filling portion 130 away from the base layer 110, so as to avoid the shading pattern 140 affecting the contact between the filter portion 120 and the base layer 110, so that the surface of the filter portion 120 close to the base layer 110 (that is, the light incident surface 122) can be adhered to the base layer 110, thereby improving the flatness of the surface of the filter portion 120 away from the base layer 110 (that is, the light emitting surface 126), so that the filter portion 120 can be a flat or nearly flat film layer structure.

[0145] In this way, the refraction effect of light on the light-emitting surface 126 can be reduced, and the light can be prevented from gathering in the central area of ​​the light-emitting surface 126, so that the brightness of the central area of ​​the light-emitting surface 126 and the brightness of the edge area can be the same or approximately the same, thereby improving the brightness uniformity of the filter part 120, that is, improving the brightness uniformity of each color sub-pixel of the display panel 200, and improving the display effect of the display panel 200.

[0146] In some examples, experiments have shown that the light adjustment structure 100 is set so that the ratio of the intensity of the reflected light irradiated outside the light adjustment structure 100 to the total intensity of the reflected light can be less than 5%, thereby further reducing the intensity of the reflected light irradiated outside the light adjustment structure 100 and improving the reliability of the light adjustment structure 100.

[0147] As can be seen from the above, the surface of the filter portion 120 close to the base layer 110 is the light incident surface 122. Figure 11As shown, the light incident surface 122 contacts the base layer 110. In some embodiments, the filter portion 120 further includes a first inclined surface 124. One end of the first inclined surface 124 is connected to the light incident surface 122, and the other end extends away from the light incident surface 122. A first angle α is formed between the first inclined surface 124 and the light incident surface 122, and the first angle α is an obtuse angle.

[0148] It can be understood that the first inclined surface 124 is disposed around the light incident surface 122. The first angle α between the first inclined surface 124 and the light incident surface 122 is an obtuse angle, that is, the first inclined surface 124 extends away from the center of the light incident surface 122 and gradually tilts.

[0149] It is understood that the first angle α is greater than 90° and less than 180°. The values ​​of the first angle α of different filter sections 120 can be the same or different. In some examples, the first angle α can be 95°, 105°, 125°, 140°, 150°, or 165°, etc.

[0150] In some examples, the shape of the filter portion 120 in a longitudinal cross-section (a cross-section perpendicular to the substrate 212) is a trapezoid, with the upper base of the trapezoid being the light incident surface 122, the lower base being the light exiting surface 126, and the waist of the trapezoid being the first inclined surface 124. It is understood that the upper base of the trapezoid is parallel to the lower base, and the length of the upper base is less than the length of the lower base.

[0151] In other examples, the shape of the filter portion 120 in the longitudinal section may also be other irregular shapes, etc. It is understandable that the shapes of the plurality of filter portions 120 in the longitudinal section may be the same or different.

[0152] The refractive index of the filling portion 130 is lower than that of the filter portion 120. It is understood that the refractive indexes of the multiple filter portions 120 may be the same or different. When the refractive indexes of the multiple filter portions 120 are different, the refractive index of the filling portion 130 is lower than that of any of the filter portions 120.

[0153] According to the conditions of total internal reflection, when light is irradiated from a denser medium (i.e., a medium with a larger refractive index) to a less dense medium (i.e., a medium with a smaller refractive index), if the incident angle θ is greater than arcsin(n2 / n1) (where n2 is the refractive index of the less dense medium, n1 is the refractive index of the denser medium, and n2 < n1), the light can be totally reflected at the contact surface between the denser medium and the less dense medium.

[0154] In this way, the filling portion 130 is located in the gap between the multiple filter portions 120, and the refractive index of the filling portion 130 is lower than the refractive index of the filter portion 120, so that a portion of the light can be totally reflected at the contact surface between the filter portion 120 and the filling portion 130, that is, a portion of the light can be totally reflected at the first inclined surface 124.

[0155] As can be seen from the above, the first angle α between the first inclined surface 124 and the light incident surface 122 is an obtuse angle, such as Figure 11 As shown in the middle light e, the light irradiated to the first inclined surface 124 is more likely to be emitted from the light regulating structure 100 under the effect of total reflection, thereby improving the utilization rate of light, increasing the brightness of each color sub-pixel of the display panel 200, and reducing the power consumption of the display panel 200.

[0156] Furthermore, the light is totally reflected on the first inclined surface 124 , which can reduce the intensity of light irradiated to other filter sections 120 via the first inclined surface 124 , thereby reducing crosstalk between two adjacent filter sections 120 and improving the display reliability of the display panel 200 .

[0157] In some embodiments, the orthographic projection of the first inclined surface 124 on the base layer 110 falls within the range of the orthographic projection of the light-shielding pattern 140 on the base layer 110 .

[0158] It can be understood that the orthographic projection of the first inclined surface 124 on the base layer 110 falls within the range of the orthographic projection of the shading pattern 140 on the base layer 110, that is, the orthographic projection of the shading pattern 140 on the base layer 110 can cover the orthographic projection of the first inclined surface 124 on the base layer 110.

[0159] Such a configuration improves the shielding effect of the shading pattern 140 on the reflected light, further reduces the intensity of the reflected light emitted from the light adjustment structure 100, reduces the impact of the reflected light on the light emitted through the filter portion 120, and improves the display effect of the display panel 200.

[0160] like Figure 1 As shown, the inventors of the present disclosure have also found that in some implementations, a portion of the light emitted by the effective light emitting portion 2152 can be emitted through the filter portion 120 (for example, Figure 1 light b), but another part of the light will be blocked by the light shielding pattern 140 (e.g. Figure 1 The light c) is reduced, thereby affecting the utilization rate of the light, reducing the brightness of each color sub-pixel of the display panel 200, and increasing the power consumption of the display panel 200.

[0161] In addition, if Figure 1As shown in the middle light ray b, a portion of the light emitted by the effective light-emitting portion 2152 cannot be emitted in a direction perpendicular to or approximately perpendicular to the light-emitting surface 126, resulting in a decrease in brightness in a direction perpendicular to or approximately perpendicular to the light-emitting surface 126, that is, a decrease in brightness in a direction perpendicular to or approximately perpendicular to the display panel 200.

[0162] When using the display panel 200 , users usually observe along a direction perpendicular to or approximately perpendicular to the display panel 200 , thereby affecting the display effect of the display panel 200 .

[0163] Figure 13 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure. Figure 14 is a structural diagram of the light shielding pattern 140 according to some embodiments. Figure 15 1 is a structural diagram of the light shielding pattern 140 according to some other embodiments. Figure 16 is a structural diagram of a display panel 200 according to some further embodiments. Figure 17 is a projected position map according to some embodiments.

[0164] In order to solve the above technical problems, Figure 13 As shown, in some other embodiments, the light shielding pattern 140 includes a main body portion 142 and an annular portion 144 .

[0165] like Figure 14 As shown, the main body 142 has a plurality of first openings 1421. It will be appreciated that the first openings 1421 extend through the light-shielding pattern 140 in a direction from the light-shielding pattern 140 to the filling portion 130. In some examples, the shape of the first openings 1421 can be rectangular, circular, elliptical, or other irregular polygonal shapes. The shapes and areas of the plurality of first openings 1421 can be the same or different.

[0166] like Figure 15 As shown, the annular portion 144 is located in the first opening 1421. In some examples, the annular portion 144 can be a rectangular ring, a circular ring, or other irregular ring shape, etc. The shapes of the multiple annular portions 144 can be the same or different.

[0167] There is a light-transmitting groove 146 between the annular portion 144 and the main body 142. It can be understood that the edge of the first opening 142 and the outer edge of the annular portion 144 are surrounded to form the light-transmitting groove 146. Figure 15 As shown, the shape of the light-transmitting groove 146 in the cross section (the cross section parallel to the substrate 212 ) is annular.

[0168] like Figure 15 As shown, a second opening 1441 is formed in the annular portion 144. Figure 16As shown, the second opening 1441 exposes the filter portion 120 . It can be understood that the second opening 1441 penetrates the light shielding pattern 140 along the direction from the light shielding pattern 140 to the filling portion 130 , so that the second opening 1441 can expose the filter portion 120 .

[0169] In some examples, the shape of the second opening 1441 can be rectangular, circular, elliptical, or other irregular polygonal shapes. The shapes and areas of the multiple second openings 1441 can be the same or different. It is understood that the number of second openings 1441 is the same as the number of first openings 1421. The shapes of the second openings 1441 and the first openings 1421 can be the same or different.

[0170] like Figure 17 As shown, at least a portion of the orthographic projection of the first inclined surface 124 on the base layer 110 is located between the orthographic projection of the main body 142 on the base layer 110 and the orthographic projection of the annular portion 144 on the base layer 110, that is, the setting position of the first inclined surface 124 corresponds to the setting position of the light-transmitting groove 146.

[0171] In this way, after a portion of the light emitted by the effective light emitting portion 2152 hits the first inclined surface 124, it can be emitted through the light-transmitting groove 146 in a direction perpendicular or approximately perpendicular to the light emitting surface 126 under the effect of total reflection (for example, Figure 13 g), while the other part of the light can be emitted directly through the light-transmitting groove 146 (for example Figure 13 Middle light f).

[0172] That is, by providing a light-transmitting groove 146 between the annular portion 144 and the main body portion 142, on the one hand, effective utilization of the light irradiated to the first inclined surface 126 is achieved, so that a portion of the light irradiated to the first inclined surface 126 can be emitted in a direction perpendicular to or approximately perpendicular to the light-emitting surface 126, thereby increasing the brightness in the direction perpendicular to or approximately perpendicular to the light-emitting surface 126, improving the brightness of each color sub-pixel, reducing the power consumption of the display panel 200, and improving the display effect of the display panel 200.

[0173] On the other hand, by setting the light-transmitting groove 146, the intensity of light irradiated in other directions (except directions perpendicular to or approximately perpendicular to the light-emitting surface 126) can also be increased, thereby increasing the light emission angle and improving the brightness of the display panel 200 in all directions, thereby further improving the display effect of the display panel 200 and reducing the power consumption of the display panel 200.

[0174] In some examples, such as Figure 17As shown, the orthographic projection of the first inclined surface 124 on the base layer 110 is located between the orthographic projection of the main body portion 142 on the base layer 110 and the orthographic projection of the annular portion 144 on the base layer 110 .

[0175] In some embodiments, as Figure 13 As shown, the light-transmitting groove 146 has a first port 152 and a second port 154. The second port 154 is closer to the base layer 110 than the first port 152. It can be understood that Figure 13 As shown, the light is irradiated to the light-transmitting slot 146 through the second port 154 and then emitted through the first port 152 .

[0176] Figure 18 2 is a position diagram of projections according to some other embodiments. Figure 19 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure.

[0177] like Figure 18 As shown, the first port 152 has a first edge L1 and a second edge L2. The orthographic projection of the first edge L1 and the orthographic projection of the second edge L2 on the base layer 110 enclose a first region P1. The second port 154 has a third edge N1 and a fourth edge N2. The orthographic projection of the third edge N1 and the orthographic projection of the fourth edge N2 on the base layer 110 both fall within the first region P1.

[0178] It can be understood that the orthographic projection of the third edge N1 on the base layer 110 and the fourth edge N2 on the base layer 110 both fall within the first region P1, that is, the setting position of the second port 154 corresponds to the setting position of the first port 152, and the area of ​​the second port 154 is smaller than the area of ​​the first port 152.

[0179] In this way, the light irradiated to the light-transmitting groove 146 can be more easily emitted through the first port 152 , thereby further improving the light utilization rate, increasing the brightness of each color sub-pixel, and reducing the power consumption of the display panel 200 .

[0180] In some examples, such as Figure 13 As shown, the light-transmitting groove 146 has a trapezoidal shape in longitudinal section. The lower base of the trapezoid is the first port 152, and the upper base of the trapezoid is the second port 154. It can be understood that the upper base of the trapezoid is parallel to the lower base, and the length of the upper base of the trapezoid is less than the length of the lower base of the trapezoid.

[0181] In other examples, the shape of the light-transmitting groove 146 in the longitudinal section may also be other irregular shapes. It is understandable that the shapes of different light-transmitting grooves 146 in the longitudinal section may be the same or different.

[0182] In some embodiments, as Figure 18 As shown, the orthographic projection of the edge of the second port 154 on the base layer 110 forms a second region P2. The orthographic projection of the first inclined surface 124 on the base layer 110 falls within the second region P2.

[0183] It can be understood that the second port 154 has a third edge N1 and a fourth edge N2 , and the orthographic projection of the third edge N1 on the base layer 110 and the orthographic projection of the fourth edge N2 on the base layer 110 enclose a second region P2 .

[0184] like Figure 18 As shown, the orthographic projection of the first inclined surface 124 on the base layer 110 falls within the second region P2, that is, the setting position of the first inclined surface 124 corresponds to the setting position of the second port 154, and the area of ​​the orthographic projection of the first inclined surface 124 on the base layer 110 is less than or equal to the area of ​​the second region P2.

[0185] In some examples, such as Figure 19 As shown, the width D1 of the orthographic projection of the first inclined surface 124 on the base layer 110 is less than or equal to the width D2 of the second port 154 , so that the orthographic projection of the first inclined surface 124 on the base layer 110 can fall into the second region P2 .

[0186] This arrangement allows light irradiating the first inclined surface 124 to more easily irradiate the light-transmitting groove 146 through the second port 154 and then be emitted through the first port 152, further improving light utilization, increasing the brightness of each color sub-pixel, and reducing power consumption of the display panel 200.

[0187] As can be seen from the above, the display substrate 210 further includes a planar layer 214. In some embodiments, as Figure 19 As shown, the light transmittance of the planar layer 214 is less than or equal to 10%.

[0188] It can be understood that the light transmittance of the planar layer 214 is less than or equal to 10%, that is, the light transmittance of the planar layer 214 ranges from 0 to 10%.

[0189] The light transmittance of the flat layer 214 is set to be less than or equal to 10%, so that the flat layer 214 can block the light reflected by the circuit structure layer 213. For example, Figure 19 As shown by the middle light q, a portion of the light emitted by the effective light emitting portion 2152 is reflected by the circuit structure layer 213 and irradiates the flat layer 214 and is blocked by the flat layer 214 .

[0190] This arrangement reduces the intensity of the reflected light irradiating the filling portion 130. Therefore, even if there is a light-transmitting groove 146 between the main body portion 142 and the annular portion 144, it is difficult for the reflected light to be emitted through the light-transmitting groove 146, thereby reducing the intensity of the reflected light emitted through the light-transmitting groove 146 and thus reducing the impact of the reflected light on the light emitted through the filter portion 120. This allows the display panel 200 to achieve an integrated black display, thereby improving the display effect of the display panel 200.

[0191] In some examples, the transmittance of the planar layer 214 may range from 0 to 8%, 0 to 5%, 0 to 3%, 0 to 1%, or 0 to 0.5%.

[0192] In some examples, the planar layer 214 is a black organic material, so that the light transmittance of the planar layer 214 can be less than or equal to 10%. For example, carbon powder and graphite can be added to the transparent organic material to form a black organic material.

[0193] Figure 20 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure.

[0194] As can be seen from the above, the display substrate 210 includes a pixel defining layer 2153. In other embodiments, such as Figure 20 As shown, the transmittance of the pixel defining layer 2153 is less than or equal to 10%.

[0195] It can be understood that the transmittance of the pixel defining layer 2153 is less than or equal to 10%, that is, the transmittance of the pixel defining layer 2153 ranges from 0 to 10%.

[0196] The transmittance of the pixel defining layer 2153 is set to be less than or equal to 10%, so that the pixel defining layer 2153 can block the light reflected by the circuit structure layer 213. For example, Figure 20 As shown by the middle light m, a portion of the light emitted by the effective light emitting portion 2152 is reflected by the circuit structure layer 213 and irradiates the pixel defining layer 2153 and is blocked by the pixel defining layer 2153 .

[0197] This arrangement reduces the intensity of the reflected light irradiating the filling portion 130. Therefore, even if there is a light-transmitting groove 146 between the main body portion 142 and the annular portion 144, it is difficult for the reflected light to be emitted through the light-transmitting groove 146, thereby reducing the intensity of the reflected light emitted through the light-transmitting groove 146 and thus reducing the impact of the reflected light on the light emitted through the filter portion 120. This allows the display panel 200 to achieve an integrated black display, thereby improving the display effect of the display panel 200.

[0198] In some examples, the transmittance of the pixel defining layer 2153 may range from 0 to 8%, 0 to 5%, 0 to 3%, 0 to 1%, or 0 to 0.5%.

[0199] In some examples, the pixel defining layer 2153 is a black organic material so that the light transmittance of the pixel defining layer 2153 is less than or equal to 10%. For example, carbon powder and graphite can be added to a transparent organic material to form a black organic material.

[0200] It can be understood that the light transmittance of the planar layer 214 and the light transmittance of the pixel defining layer 2153 can be the same or different.

[0201] In some other examples, the transmittance of the flat layer 214 is less than or equal to 10%, and the transmittance of the pixel defining layer 2153 is less than or equal to 10%, which further reduces the intensity of the reflected light irradiated to the filling portion 130 and reduces the intensity of the reflected light emitted through the light-transmitting groove 146, thereby improving the display effect of the display panel 200.

[0202] In some examples, the light transmittance of the planar layer 214 and the light transmittance of the pixel defining layer 2153 are both less than or equal to 1%.

[0203] As can be seen from the above, the surface of the filter portion 120 away from the base layer 110 is the light emitting surface 126. Figure 11 As shown, the light emitting surface 126 is connected to an end of the first inclined surface 124 away from the light incident surface 122 .

[0204] like Figure 20 As shown, the filling portion 130 includes a second inclined surface 132. One end of the second inclined surface 132 contacts the light-emitting surface 126, and the other end extends away from the light-emitting surface 126. The second inclined surface 132 gradually inclines toward a first direction. The first direction is a direction away from the centerline H of the filter portion 120. The centerline H of the filter portion 120 is located at the center of the filter portion 120 and is perpendicular to the light-emitting surface 126.

[0205] It is understandable that the center line H of the filter portion 120 is a virtual straight line, located at the center or approximately at the center of each filter portion 120 , and perpendicular to the light emitting surface 126 .

[0206] like Figure 20 As shown, one end of the second inclined surface 132 is in contact with the light emitting surface 126, and the other end extends in a direction away from the light emitting surface 126, and gradually tilts in a direction away from the center line H of the filter portion 120, so that a second angle β is formed between the second inclined surface 132 and the central area of ​​the light emitting surface 126, and the second angle β is an obtuse angle, that is, the second angle β is greater than 90° and less than 180°.

[0207] With this arrangement, when light is irradiated onto the second inclined surface 132, a portion of the light can be emitted in a direction perpendicular to or approximately perpendicular to the light emitting surface 126 under the reflection effect of the second inclined surface 132 (for example, Figure 20 The middle light n) increases the brightness in the direction perpendicular to or approximately perpendicular to the light emitting surface 126, that is, increases the brightness in the direction perpendicular to or approximately perpendicular to the display panel 200, improves the display effect of the display panel 200, and can also reduce the power consumption of the display panel 200.

[0208] In some examples, the values ​​of different second angles β may be the same or different. For example, the second angle β may be 95°, 105°, 125°, 140°, 150°, or 165°.

[0209] Figure 21 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure. Figure 22 2 is a structural diagram of a display panel 200 according to some further embodiments of the present disclosure. Figure 23 2 is a structural diagram of a display panel 200 according to some other embodiments of the present disclosure.

[0210] In some embodiments, as Figure 21 As shown, the light modulation structure 100 further includes a color filter film 172. The color filter film 172 is located on a side of the base layer 110 close to the light shielding pattern 140. The orthographic projection of the color filter film 172 on the base layer 110 at least partially overlaps with the orthographic projection of the light shielding pattern 140 on the base layer 110.

[0211] It is understood that the color filter film 172 is used to filter light. In some examples, the color filter film 172 can be used to filter any one of red light, green light, and blue light, that is, to allow any one of red light, green light, and blue light to pass through the color filter film 172.

[0212] The orthographic projection of the color filter film 172 on the base layer 110 at least partially overlaps with the orthographic projection of the light-shielding pattern 140 on the base layer 110. For example, the orthographic projection of the color filter film 172 on the base layer 110 may partially overlap or completely overlap with the orthographic projection of the light-shielding pattern 140 on the base layer 110. In some examples, the orthographic projection of the color filter film 172 on the base layer 110 falls within the range of the orthographic projection of the light-shielding pattern 140 on the base layer 110.

[0213] As can be seen from the above description, some of the multiple effective light-emitting portions 2152 emit red light, some emit green light, and some emit blue light. The color filter 172 can filter any one of red, green, and blue light. That is, light emitted by one of the three effective light-emitting portions 2152 emitting red light, green light, and blue light can pass through the color filter 172, while light emitted by the other two cannot.

[0214] A color filter film 172 is provided on one side of the base layer 110 close to the light-shielding pattern 140 , and the orthographic projection of the color filter film 172 on the base layer 110 at least partially overlaps with the orthographic projection of the light-shielding pattern 140 on the base layer 110 , so that the color filter film 172 can filter the reflected light.

[0215] In this way, when the light emitted by the effective light-emitting portion 2152 is irradiated onto the color filter film 172 under the reflection effect of the circuit structure layer 213 or the anode layer AND, only one color of reflected light (that is, the reflected light of the same color as the color filter film 172) can pass through the color filter film 172, while the reflected light of the other two colors cannot pass through the color filter film 172, thereby further reducing the intensity of the reflected light emitted from the light adjustment structure 100 and reducing the impact of the reflected light on the light emitted through the filter portion 120.

[0216] In some embodiments, the color filter film 172 can expose the red filter portion 120R, the green filter portion 120G, and the blue filter portion 120B, so as to prevent the color filter film 172 from blocking the light filtered by the plurality of filter portions 120 .

[0217] In other embodiments, the color filter film 172 can expose the filter portion 120 of a different color. That is, when the color filter film 172 is a red color filter film, the green filter portion 120G and the blue filter portion 120B can be exposed, thereby preventing the color filter film 172 from blocking the light filtered by the filter portion 120 of a different color.

[0218] In some embodiments, the color filter film 172 can also expose the light-transmitting grooves 146 , further reducing the blocking of the light filtered by the light filter portion 120 by the color filter film 172 , so that the light filtered by the light filter portion 120 can be emitted through the light-transmitting grooves 146 .

[0219] The color filter film 172 is located on the side of the base layer 110 close to the light shielding pattern 140. It can be understood that the color filter film 172 can be located between the base layer 110 and the filling portion 130, between the filling portion 130 and the light shielding pattern 140, or on the side of the light shielding pattern 140 away from the filling portion 130. Figures 21 to 23 , the positional relationship among the color filter film 172, the filling portion 130 and the light shielding pattern 140 is described with an example.

[0220] In some examples, such as Figure 21 As shown, the color filter film 172 is located between the base layer 110 and the filling portion 130. For example, the color filter film 172 is located in the gaps between the plurality of filter portions 120 and around the entirety of the plurality of filter portions 120, and the filling portion 130 is located on a side of the color filter film 172 away from the base layer 110. In some examples, the filling portion 130 may be in contact with a surface of the color filter film 172 away from the base layer 110.

[0221] like Figure 21 As shown, the thickness H2 of the filter portion 120 is greater than the thickness H3 of the color filter film 172. This configuration allows the filling portion 130 to fill the gaps between the plurality of filter portions 120, so that a portion of the light emitted by the effective light emitting portion 2152 can be totally reflected at the contact surface between the filter portion 120 and the filling portion 130 (i.e., a portion of the first inclined surface 124) and emitted through the light-transmitting groove 146 (e.g., Figure 21 Medium light s), improve the utilization rate of light.

[0222] The color filter film 172 is disposed between the base layer 110 and the filling portion 130. Figure 21 As shown by the middle light ray r, even if the reflected light passes through the pixel defining layer 2153 (or the planar layer 214) with a low light transmittance, it will be filtered by the color filter film 172 after it hits the color filter film 172. Therefore, only the reflected light of the same color as the color filter film 172 can pass through the color filter film 172, while the reflected light of the other two colors cannot pass through the color filter film 172. This reduces the intensity of the reflected light hitting the light shielding pattern 140, further reducing the intensity of the reflected light exiting the light modulation structure 100, and reducing the impact of the reflected light on the light emitted through the filter portion 120.

[0223] The following describes the preparation method of the color filter film 172 in some examples of the present disclosure.

[0224] For example, a preliminary color filter film can be formed on a side of the base layer 110 away from the substrate 212, and a plurality of spaced-apart receiving holes can be formed in the preliminary color filter film to expose the base layer 110, thereby preparing the color filter film 172. A plurality of filter sections 120 (including a plurality of red filter sections 120R, a plurality of green filter sections 120G, and a plurality of blue filter sections 120B) are formed in the plurality of receiving holes, and a thickness H2 of each filter section 120 is greater than a thickness H3 of the color filter film 172, so that the color filter film 172 can be located in the gaps between the plurality of filter sections 120 and around the entirety of the filter sections 120.

[0225] For example, using the red color filter film 172 as an example, after forming the initial color filter film, a portion of the initial color filter film may be thinned to produce a patterned red filter portion 120R. A plurality of spaced-apart receiving holes are formed in the thinned region of the initial color filter film to expose the base layer 110, and the color filter film 172 is produced. A plurality of filter portions 120 (including a plurality of green filter portions 120G and a plurality of blue filter portions 120B) are formed within the plurality of receiving holes. The thickness H2 of each filter portion 120 is greater than the thickness H3 of the color filter film 172, allowing the color filter film 172 to be positioned within the gaps between the plurality of filter portions 120 and around the entirety of the filter portion 120.

[0226] In other examples, such as Figure 22 As shown, the color filter film 172 is located between the filling portion 130 and the light shielding pattern 140. Figure 22 As shown by the middle light ray x, even if the reflected light passes through the pixel defining layer 2153 (or the planar layer 214) with a low light transmittance, it will be filtered by the color filter film 172 after it hits the color filter film 172. Therefore, only the reflected light of the same color as the color filter film 172 can pass through the color filter film 172, while the reflected light of the other two colors cannot pass through the color filter film 172. This reduces the intensity of the reflected light hitting the light shielding pattern 140, further reducing the intensity of the reflected light exiting the light modulation structure 100, and reducing the impact of the reflected light on the light emitted through the filter portion 120.

[0227] In some other examples, such as Figure 23 As shown, the color filter film 172 is located on the side of the light shielding pattern 140 away from the filling portion 130, as shown in FIG. Figure 23 As shown by the middle light y, even if the reflected light passes through the pixel defining layer 2153 (or the planar layer 214) with low light transmittance and the light shielding pattern 140, it will be filtered by the color filter film 172 after being irradiated by the color filter film 172. Therefore, only the reflected light of the same color as the color filter film 172 can pass through the color filter film 172 and irradiate the light modulation structure 100, while the reflected light of the other two colors cannot pass through the color filter film 172. This reduces the intensity of the reflected light emitted from the light modulation structure 100 and further reduces the impact of the reflected light on the light emitted through the filter portion 120.

[0228] In some embodiments, as Figure 20 As shown, the light-modulating structure 100 further includes a covering layer 160. The covering layer 160 is located on a side of the plurality of filter portions 120, the filling portion 130, and the light-shielding pattern 140 away from the base layer 110. The covering layer 160 covers the plurality of filter portions 120, the filling portion 130, and the light-shielding pattern 140, and the refractive index of the covering layer 160 is greater than or equal to the refractive index of the filter portion 120.

[0229] It can be understood that the covering layer 160 can protect the plurality of filter portions 120 , the filling portion 130 and the light shielding pattern 140 .

[0230] In some examples, the cover layer 160 is a transparent organic material to prevent the cover layer 160 from blocking light, so that the light can be emitted from the light modulation structure 100 through the cover layer 160 .

[0231] It is understood that when the refractive indices of the light of the multiple filter sections 120 are different, the refractive index of the cover layer 160 is greater than or equal to the refractive index of any of the filter sections 120. This configuration prevents light emitted from the filter sections 120 from being totally reflected at the light exit surface 126 (i.e., the interface between the filter sections 120 and the cover layer 160), making it easier for light to pass through the light exit surface 126 and reach the cover layer 160, thereby improving light utilization and reducing power consumption of the display panel 200.

[0232] As can be seen from the above, the refractive index of any filter portion 120 is greater than the refractive index of the filling portion 130. In this way, the refractive index of the covering layer 160 is set to be greater than the refractive index of any filter portion 120, so that the refractive index of the covering layer 160 can also be greater than the refractive index of the filling portion 130.

[0233] like Figure 20 As shown by the middle light ray n, since the refractive index of the covering layer 160 is greater than the refractive index of the filling portion 130, a portion of the light irradiated to the contact surface between the covering layer 160 and the filling portion 130 can be totally reflected, that is, a portion of the light irradiated to the second inclined surface 132 can be totally reflected, further improving the intensity of the light irradiated to the light regulating structure 100, thereby improving the light utilization rate, increasing the brightness of each color sub-pixel, and reducing the power consumption of the display panel 200.

[0234] Figure 24 4 is a flowchart of the steps of a method for preparing a light-regulating structure according to some embodiments of the present disclosure.

[0235] On the other hand, the embodiment of the present disclosure provides a method for preparing a light regulating structure, which is used to prepare the light regulating structure 100 described above. Figure 24 As shown, the preparation method of the light-modulating structure includes:

[0236] Step S101: forming a plurality of filter portions on one side of a base layer. The plurality of filter portions are arranged at intervals.

[0237] Step S102: forming a filling portion. The filling portion is located in the gaps between the plurality of filter portions and around the entirety of the plurality of filter portions. Furthermore, the filling portion covers the edge of at least one filter portion on a side away from the base layer.

[0238] Step S103: forming a light shielding pattern. The light shielding pattern is located on the surface of the filling portion away from the base layer.

[0239] The method for preparing a light regulating structure provided by the embodiment of the present disclosure is used to prepare the light regulating structure 100 described above, and thus has all the above-mentioned beneficial effects, which will not be described in detail here.

[0240] In some examples, a photolithography process can be used to form a plurality of spaced filter portions 120 on one side of the substrate layer. The gaps between the filter portions 120 and the surrounding areas of the plurality of filter portions are filled to form a filling portion 130. It will be appreciated that, to ensure that the filling portion 130 fills the gaps between the plurality of filter portions 120 and avoids the formation of gaps between the filling portion 130 and the filter portion 120, the filling portion 130 can be arranged to cover the edge portion of at least one filter portion 120 on the side of the surface away from the substrate layer 110.

[0241] A light shielding pattern 140 is formed on a side of the filling portion 130 away from the base layer 110. In some examples, after forming the light shielding pattern 140, a photolithography process may be used to form the first opening 1421 and the second opening 1441 on the light shielding pattern 140.

[0242] It can be understood that the method for preparing the light-regulating structure provided by the embodiment of the present disclosure is simple in process and reduces the production cost of the light-regulating structure 100 .

[0243] In some embodiments, the method for preparing the light-modulating structure further comprises:

[0244] A covering layer is formed. The covering layer is located on a side of the plurality of filter portions, the filling portion, and the light-shielding pattern away from the base layer. The covering layer covers the plurality of filter portions, the filling portion, and the light-shielding pattern, and the light refractive index of the covering layer is greater than or equal to the light refractive index of the filter portions.

[0245] It can be understood that the covering layer 160 can protect the plurality of filter portions 120 , the filling portion 130 and the light shielding pattern 140 .

[0246] As can be seen from the above, the refractive index of any filter portion 120 is greater than the refractive index of the filling portion 130. In this way, the refractive index of the covering layer 160 is set to be greater than the refractive index of any filter portion 120, so that the refractive index of the covering layer 160 can also be greater than the refractive index of the filling portion 130.

[0247] For example, Figure 20As shown by the middle light ray n, since the refractive index of the covering layer 160 is greater than the refractive index of the filling portion 130, a portion of the light irradiated to the contact surface between the covering layer 160 and the filling portion 130 can be totally reflected, that is, a portion of the light irradiated to the second inclined surface 132 can be totally reflected, further improving the intensity of the light irradiated to the light regulating structure 100, thereby improving the light utilization rate, increasing the brightness of each color sub-pixel, and reducing the power consumption of the display panel 200.

[0248] Figure 25 is a structural diagram of an electronic device 300 according to some embodiments of the present disclosure.

[0249] On the other hand, an embodiment of the present disclosure provides an electronic device 300, which includes the above-mentioned display panel 200 to realize the image display function, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0250] In some examples, the electronic device 300 may be a mobile phone, tablet computer, television, smart wearable product (e.g., smart watch, smart bracelet), virtual reality terminal device, augmented reality terminal device, or other electronic device 300 with image display function.

[0251] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present disclosure should be included within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
