Furthermore, because the light emitted by each light-emitting device can pass through the reflection reduction layer, the reflection reduction layer does not block normal light output. Thus, the reflection reduction layer can replace a complex circular polarizer, reducing the thickness of the display panel while also reducing ambient light reflection. Furthermore, the reflection reduction units of different thicknesses have different degrees of absorption of ambient light, which can be used to compensate for differences in luminous efficiency between light-emitting devices of different luminous colors, thereby improving brightness uniformity. Furthermore, specific patterns (such as product logos) can be formed in the dark state.

However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent identical or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0072] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0073] The "overlap" of feature A and feature B in this article means that the orthographic projection of feature A on a plane and the orthographic projection of feature B on the same plane at least partially overlap; the plane can be the surface of the driver backplane or other plane parallel to the driver backplane.

[0074] Embodiments of the present disclosure provide a display panel, as shown in FIG1 . The display panel includes a display area AA and a peripheral area WA located outside the display area AA. The peripheral area WA can be a continuous annular area surrounding the display area AA, or a discontinuous area surrounding the display area AA. For example, the peripheral area WA can be distributed on both sides of the display area AA. The display area AA can be configured to emit light to display images, while the peripheral area WA does not emit light.

[0075] As shown in FIG2 to FIG11 , the display panel may include a driving backplane BP and a plurality of light-emitting devices LD provided on one side of the driving backplane BP, wherein:

[0076] The driving backplane BP includes a driving circuit that drives the light-emitting devices LD to emit light, thereby displaying images. In some embodiments of the present disclosure, the driving backplane BP may include a substrate SU and a circuit layer CL located on one side of the substrate SU. The substrate SU may be a flat plate made of either a rigid material such as glass or a flexible material such as polyimide. Furthermore, the substrate SU may have a single-layer or multi-layer structure.

[0077] The circuit layer CL includes the aforementioned drive circuit. For example, the drive circuit may include a pixel circuit located in the display area AA and a peripheral circuit located in the peripheral area WA. The pixel circuit may have a 7T1C, 8T1C, or other structure, as long as it can drive the light-emitting device LD to emit light. There is no specific limitation on its structure. Here, nTmC indicates that a pixel circuit includes n thin-film transistors (represented by the letter "T") and m capacitors (represented by the letter "C"). The number of pixel circuits may be the same as the number of light-emitting devices LD, and each light-emitting device LD is connected in a one-to-one correspondence. Of course, the same pixel circuit may also be connected to multiple light-emitting devices LD, and this is not specifically limited here.

[0078] The peripheral circuit is connected to the pixel circuit and is used to input a drive signal to the pixel circuit to control the light emitting device LD to emit light. The peripheral circuit may include a gate drive circuit and a light emitting control circuit. Of course, it may also include other circuits. The specific structure of the peripheral circuit is not particularly limited here.

[0079] The circuit layer CL may include multiple thin-film transistors (TFTs) and capacitors. The TFTs may be top-gate or bottom-gate TFTs, each including an overlapping active layer and gate. The active layers of each TFT are co-located within the same semiconductor layer. Alternatively, the active layers may be arranged across multiple semiconductor layers, with the active layers of different TFTs located in different semiconductor layers. The semiconductor layer may be made of either polysilicon or a metal oxide, without particular limitation.

[0080] Taking the top-gate thin film transistor as an example, the circuit layer CL may include a semiconductor layer, a first gate insulation layer, a first gate layer, a second gate insulation layer, a second gate layer, an interlayer dielectric layer, a first source and drain layer, a passivation layer, a first flat layer, a second source and drain layer, and a second flat layer stacked in sequence along the direction away from the substrate SU. The active layer of the thin film transistor is located in the semiconductor layer, the gate is located in the gate layer, and the two plates of the capacitor are located in the first gate layer and the second gate layer. The first source and drain layer and the second source and drain layer are used to achieve connection between at least part of the thin film transistors and between the thin film transistors and the capacitors, and are used to transmit driving signals. The type of driving signal and the specific pattern of each film layer depend on the specific composition of the driving circuit and are not specifically limited here.

[0081] The light-emitting device LD can be located in the display area AA. It can be an OLED (organic light-emitting diode) using organic light-emitting materials, or a Mini LED (sub-millimeter light-emitting diode, with a size of 100μm-200μm), Micro LED (micro light-emitting diode, with a size not greater than 100μm) and LED (light-emitting diode, with a size greater than 200μm) using inorganic light-emitting materials, etc. There is no special limitation here, as long as it can emit light.

[0082] As shown in Figures 2 to 11, taking the light-emitting device LD as an example of an OLED, the light-emitting device LD may include a first electrode ANO, a light-emitting layer EL, and a second electrode CAT stacked in sequence in a direction away from the driving backplane BP. By applying an electrical signal to the first electrode ANO and the second electrode CAT, the light-emitting layer EL can be stimulated to emit light. The specific light-emitting principle will not be described in detail here. The first electrode ANO can be used as an anode, and the second electrode CAT can be used as a cathode. The materials of the two include conductive materials such as metals and metal oxides. The light-emitting layer EL may include a hole injection layer, a hole transport layer, a light-emitting material layer, an electron transport layer, and an electron injection layer stacked in sequence in a direction away from the driving backplane BP. Of course, other structures can also be used as long as they can cooperate with the first electrode ANO and the second electrode CAT to emit light.

[0083] As shown in Figures 2-11 , the display panel may further include a pixel definition layer PDL that separates the light-emitting devices LD. The pixel definition layer PDL and the light-emitting devices LD may be disposed on the same surface of the driving backplane BP. For example, the pixel definition layer PDL and the first electrodes ANO may be disposed on a surface of the second planar layer away from the substrate SU. The pixel definition layer PDL is thicker than the first electrodes ANO, covers a portion of each first electrode ANO, and has pixel openings PH that expose each first electrode ANO, with each pixel opening PH exposing one first electrode ANO.

[0084] As shown in Figures 2-11, the light-emitting layer EL and the second electrode CAT are sequentially stacked on the first electrode ANO within the pixel opening PH. In some embodiments, the light-emitting layer EL has a discontinuous structure, with the light-emitting layer EL of each light-emitting device LD independently spaced apart. This allows different light-emitting devices LD to emit different colors. The second electrode CAT has a continuous, single-layer structure, with the portion of the second electrode CAT located within the pixel opening PH covering the light-emitting layer EL. The portion of the second electrode CAT located outside the pixel opening PH may also cover the pixel definition layer PDL. The combined thickness of the light-emitting layer EL and the second electrode CAT is less than the thickness of the pixel definition layer PDL, resulting in the second electrode CAT being recessed within the pixel opening PH.

[0085] As shown in Figures 2-11, each light-emitting device LD is defined by the pixel definition layer PDL. The extent of the pixel opening PH corresponds to the extent of the light-emitting device LD. Specifically, the shape and size of the orthographic projection of the pixel opening PH on the substrate SU correspond to the shape and size of the orthographic projection of the light-emitting device LD on the substrate SU. Furthermore, the shape of the pixel opening PH corresponds to the shape of its orthographic projection on the driver backplane BP and substrate SU, and can be a polygon, such as a rectangle, or a circle. The definition of the shape and size of the light-emitting device LD herein is based on the shape and size of the pixel opening PH. For example, the size of the light-emitting device LD corresponds to the size of its pixel opening PH.

[0086] As shown in Figures 2 to 11, the above-mentioned light-emitting device LD includes at least two light-emitting devices LD with different luminous colors. Each light-emitting device LD can be divided into multiple light-emitting units. One light-emitting unit includes multiple light-emitting devices LD, and at least some of the light-emitting devices LD in the same light-emitting unit have different luminous colors.

[0087] As shown in Figures 2 to 11, in some embodiments of the present disclosure, each light-emitting device LD includes a first light-emitting device LD1, a second light-emitting device LD2, and a third light-emitting device LD3 with different luminous colors. For example, the first light-emitting device LD1 is used to emit red light, the second light-emitting device LD2 is used to emit green light, and the third light-emitting device LD3 is used to emit blue light.

[0088] There are multiple light emitting devices LD of each color, but the number of light emitting devices LD of different colors is not necessarily the same. For example, the same light emitting unit includes a first light emitting device LD1, a second light emitting device LD2 and a third light emitting device LD3.

[0089] As shown in Figures 2 to 11, in some embodiments of the present disclosure, due to the difference in the lifespan of the light-emitting layer EL of light-emitting devices LD of different light-emitting colors, the degree of decay of the light-emitting efficiency is different as the light-emitting time increases. In order to ensure different light-emitting efficiencies, the sizes of the light-emitting devices LD can be made different, and a larger size can be used to make up for the lack of light-emitting efficiency. For example, under the same light-emitting time, in terms of the degree of decay of the light-emitting efficiency, the material that emits blue light is smaller than the material that emits red light, and the material that emits red light is smaller than the material that emits green light. Therefore, the size of the third light-emitting device LD3 can be larger than the size of the first light-emitting device LD1, and the size of the first light-emitting device LD1 can be larger than the size of the second light-emitting device LD2, so that the brightness of the three can be uniformly improved.

[0090] Of course, in other embodiments of the present disclosure, due to different luminescent materials, subjective preferences for pictures, or requirements of usage scenarios, the sizes of the first light-emitting device LD1, the second light-emitting device LD2, and the third light-emitting device LD3 may also be different. However, this is not limited to the size of the third light-emitting device LD3 being larger than the size of the first light-emitting device LD1, and the size of the first light-emitting device LD1 being larger than the size of the second light-emitting device LD2. Instead, the size of any one of the three may be the largest, the three may be the same, or other forms may be used to obtain a specific hue. In other words, the size relationship of the light-emitting devices LD does not necessarily have to adopt a certain size relationship.

[0091] As shown in FIG2 to FIG11, in order to prevent corrosion from external water vapor, the display panel may further include an encapsulation layer TFE, which may cover each light-emitting device LD. For example, the encapsulation layer TFE may be a thin film encapsulation method, which may include a first inorganic layer CVD1, an organic layer IJP, and a second inorganic layer CVD2, wherein:

[0092] The first inorganic layer CVD1 may cover each light-emitting device LD, that is, the first inorganic layer CVD1 may cover the surface of the second electrode CAT away from the driving backplane BP. The thickness of the first inorganic layer CVD1 is less than that of the pixel definition layer PDL and is recessed at the pixel opening PH. The material of the first inorganic layer CVD1 may include an inorganic insulating material such as silicon nitride and silicon oxide.

[0093] The organic layer IJP can be disposed on the surface of the first inorganic layer CVD1 away from the driving backplane BP. A barrier dam located in the peripheral area WA can be used to confine the boundary of the organic layer IJP to the inside of the boundary of the first inorganic layer CVD1. Furthermore, the boundary of the orthographic projection of the organic layer IJP on the driving backplane BP can be located in the peripheral area WA, ensuring that the organic layer IJP covers each light-emitting device LD.

[0094] The second inorganic layer CVD2 can cover the organic layer IJP and the first inorganic layer CVD1 not covered by the organic layer IJP. The second inorganic layer CVD2 can block the intrusion of water and oxygen, and achieve planarization through the organic layer IJP, which has fluidity before curing. The second inorganic layer CVD2 can be made of inorganic insulating materials such as silicon nitride and silicon oxide.

[0095] As shown in Figures 2-11, the display panel may also include a touch layer TPS, which may be located on the side of the encapsulation layer TFE away from the driver backplane BP and is used to sense touch operations. Taking the example of a mutual capacitance touch structure employed by the touch layer TPS, the touch layer TPS may include multiple first touch electrodes and multiple second touch electrodes. Each first touch electrode may be spaced apart along the row direction. A first touch electrode may include multiple first electrode blocks spaced apart along the column direction and a transfer bridge connecting two adjacent first electrode blocks. Each second touch electrode may be spaced apart along the column direction. A second touch electrode may include multiple second electrode blocks connected in series along the row direction. A transfer bridge intersects with a second touch electrode and is insulated therefrom. One of the first and second touch electrodes may serve as a transmitting electrode, the other as a receiving electrode, and both are connected to the touch drive circuit in the peripheral area WA.

[0096] The row and column directions herein are simply two intersecting directions, and they may be perpendicular to each other or intersect at an angle other than 90°. In the drawings of this disclosure, the row direction is horizontal and the column direction is vertical, but this is not limiting. Those skilled in the art will appreciate that the actual orientation of the row and column directions may change if the display panel is rotated.

[0097] As shown in Figures 2-11, for a mutual capacitance touch structure, the touch layer TSP may include a first conductive layer TMA, an isolation layer SEP, and a second conductive layer TMB, distributed in a direction away from the driving backplane BP. The first conductive layer TMA may include the aforementioned transfer bridge, the specific pattern of which is not specifically limited herein. The isolation layer SEP may at least cover the transfer bridge of the first conductive layer TMA, and the isolation layer SEP is made of an inorganic insulating material such as silicon nitride or silicon oxide. The aforementioned first electrode block and second touch electrode are both located in the second conductive layer TMB, that is, the first electrode block and the second touch electrode are arranged in the same layer, so that they can be formed simultaneously using the same process.

[0098] The second conductive layer TMB may have a mesh structure with multiple meshes, with each mesh overlapping a light-emitting device LD so that light emitted by the light-emitting device LD can be emitted from the mesh. The meshes and light-emitting devices LD may have a one-to-one correspondence; alternatively, a single mesh may overlap with multiple light-emitting devices LD simultaneously, i.e., the orthographic projections of the multiple light-emitting devices LD on the driver backplane BP are within the orthographic projection of the same mesh on the driver backplane BP, as long as the light emitted by the light-emitting device LD can be emitted.

[0099] Both the first conductive layer TMA and the second conductive layer TMB may be made of conductive materials such as metals, metal oxides, and alloys, and both may be single-layer or multi-layer structures. Taking the second conductive layer TMB with a multi-layer structure as an example, it may include a first conductive material layer, a second conductive material layer, and a third conductive material layer stacked in sequence in a direction away from the driving backplane BP. The material of the second conductive material layer is different from that of the first conductive material layer and the third conductive material layer, and the resistivity of the second conductive material layer is lower than that of the first conductive material layer and the third conductive material layer. The chemical stability of the first conductive material layer and the third conductive material layer is higher than that of the second conductive material layer. For example, the material of the second conductive material layer is aluminum, silver, etc., and the materials of the first conductive material layer and the third conductive material layer are titanium, titanium oxide, indium tin oxide, etc.

[0100] As shown in FIG2-FIG11, the touch layer TPS may further include a buffer layer TLD, which may be disposed on a surface of the encapsulation layer TFE away from the driving backplane BP. The material thereof may be insulating materials such as silicon nitride and silicon oxide, which are not particularly limited here.

[0101] Furthermore, as shown in FIG. 2 to FIG. 4 , in the first embodiment of the present disclosure, the display panel further includes an insulating cover layer TOC and a light absorbing layer TBM, wherein:

[0102] The insulating cover layer TOC may cover the second conductive layer TMB, protecting the second conductive layer TMB and achieving planarization. The insulating cover layer TOC may be made of an organic material such as an optical adhesive, for example, a negative photoresist. The insulating cover layer TOC is thicker than any of the first conductive layer TMA, the isolation layer SEP, and the second conductive layer TMB to achieve planarization.

[0103] The light absorbing layer TBM can be provided on the surface of the insulating cover layer TOC away from the driving backplane BP and overlapped with the second conductive layer TMB. The light absorbing layer TBM can be made of a material that can absorb light, such as black resin, to reduce the reflection of ambient light by the second conductive layer TMB. For example, the dielectric constant of the black resin is ≤4.0 and the volume resistivity is ≤10 4 The pattern of the light absorbing layer TBM is the same as the pattern of the second conductive layer TMB.

[0104] At the mesh holes TH of the second conductive layer TMB, the light absorbing layer TBM forms light-transmitting holes TBH. Each light-transmitting hole TBH overlaps with a light-emitting device LD, allowing light emitted by the light-emitting device LD to exit through the light-transmitting hole TBH. The light-transmitting holes TBH and the light-emitting devices LD can have a one-to-one correspondence; alternatively, a light-transmitting hole TBH can overlap with multiple light-emitting devices LD simultaneously, that is, the orthographic projections of the multiple light-emitting devices LD on the driver backplane BP are located within the orthographic projection of the same light-transmitting hole TBH on the driver backplane BP, as long as the light emitted by the light-emitting device LD can exit.

[0105] As shown in FIG5 , in the second embodiment of the present disclosure, the display panel further includes a light absorbing layer TBM, but does not include an insulating cover layer TOC in the same position as in the first embodiment, wherein:

[0106] The isolation layer SEP can be made of organic materials such as optical glue, that is, the same material as the above-mentioned insulating covering layer TOC, and its thickness is greater than the first conductive layer TMA and the second conductive layer TMB. The isolation layer SEP covers the first conductive layer TMA and the buffer layer TLD, and the second conductive layer TMB is arranged on the surface of the isolation layer SEP away from the driving backplane BP.

[0107] The light-absorbing layer TBM can directly cover the second conductive layer TMB, and the pattern of the light-absorbing layer TBM is the same as that of the second conductive layer TMB. The second conductive layer TMB has a mesh hole TH, and at the mesh hole TH, the light-absorbing layer TBM forms an opening, namely a light-transmitting hole TBH. The light-absorbing layer TBM can be made of a light-absorbing material such as black resin to reduce the reflection of ambient light from the second conductive layer TMB. At the same time, the light-absorbing layer TBM has a light-transmitting hole TBH that overlaps with the light-emitting device LD. The specific arrangement of the light-transmitting hole TBH can refer to the first embodiment above and will not be described in detail here.

[0108] As shown in FIG6 , in a third embodiment of the present disclosure, the display panel further includes an insulating cover layer TOC and a light absorbing layer TBM, wherein:

[0109] The light-absorbing layer TBM can directly overlie the second conductive layer TMB, and the pattern of the light-absorbing layer TBM is the same as that of the second conductive layer TMB. The second conductive layer TMB has mesh holes TH, and at the mesh holes TH, the light-absorbing layer TBM also forms openings, namely light-transmitting holes TBH. The light-absorbing layer TBM can be made of a light-absorbing material such as black resin to reduce the reflection of ambient light from the second conductive layer TMB. The light-absorbing layer TBM has light-transmitting holes TBH that overlap with the light-emitting devices LD. The specific arrangement of the light-transmitting holes TBH can be referred to in the first embodiment above and will not be described in detail here.

[0110] The insulating cover layer TOC can cover the light absorbing layer TBM to achieve planarization. The insulating cover layer TOC can be made of organic materials such as optical adhesive and has a thickness greater than any of the first conductive layer TMA, the isolation layer SEP, the second conductive layer TMB, and the light absorbing layer TBM.

[0111] As shown in FIG8 , in a fourth embodiment of the present disclosure, the display panel further includes an insulating cover layer TOC, but does not include the light absorbing layer TBM mentioned above, wherein:

[0112] The insulating cover layer TOC may cover the second conductive layer TMB, protecting the second conductive layer TMB and achieving planarization. The insulating cover layer TOC may be made of an organic material such as optical adhesive and may be thicker than any of the first conductive layer TMA, the isolation layer SEP, and the second conductive layer TMB to achieve planarization.

[0113] The second conductive layer TMB includes a light-absorbing conductive material. The second conductive layer TMB can be directly utilized to absorb ambient light, fulfilling the function of the light-absorbing layer TBM described above. This eliminates the need for the TBM layer, facilitating a reduction in the thickness of the display panel. The light-absorbing conductive material can be molybdenum oxide or other materials with similar functions. For example, at least one of the first conductive material layer, the second conductive material layer, and the third conductive material layer can be a light-absorbing conductive material. Furthermore, the third conductive material layer can be a light-absorbing conductive material to prevent the first and second conductive material layers from reflecting ambient light. In some embodiments, the third conductive material layer can be molybdenum oxide, the second conductive material layer can be aluminum, and the first conductive material layer can be titanium.

[0114] The light absorbing layer BM of black resin and molybdenum oxide (MoO x The comparison of reflectivity at different thicknesses for 550nm wavelength light is shown in the following table:

[0115] In the fourth embodiment, there is no light absorbing layer TBM, and thus no light-transmitting holes, and light is transmitted through the mesh holes TH of the second conductive layer TMB.

[0116] In some embodiments of the present disclosure, the touch layer TPS may also adopt a self-capacitive touch structure, which may include a plurality of electrode blocks distributed in an array, each electrode block having a light-transmitting hole overlapping with the light-emitting device LD, and each electrode block may be connected to the peripheral touch drive circuit through an independent wiring. Each electrode block may be located on the same layer, which can reduce one conductive layer compared to the mutual capacitance touch structure, that is, the display panel may include a conductive layer, the electrode blocks are located on the conductive layer, and the insulating covering layer may cover the conductive layer. The display panel may also shield the pattern of the electrode blocks by a light-absorbing layer; alternatively, the electrode blocks may be formed of a light-absorbing conductive material, thereby eliminating the light-absorbing layer. The position of the light-absorbing layer and the light-absorbing conductive material may refer to the above embodiments and will not be described in detail here.

[0117] To reduce reflection of ambient light, a GOC layer can be provided on the side of the light-emitting device LD away from the driver backplane BP. The GOC layer can be made of colored photoresist or other materials. It can transmit light of the same color as the light-emitting device LD and absorb at least some light of a different color than the light-emitting device LD. For example, the light-emitting devices LD include a first light-emitting device LD1 that emits red light, a second light-emitting device LD2 that emits green light, and a third light-emitting device LD3 that emits blue light. The GOC layer can transmit red, green, and blue light and absorb light of other colors except red, green, and blue. Referring to Figure 12, Figure 12 shows the transmittance of the GOC layer for light of different wavelengths, where G represents green light, R represents red light, and B represents blue light. While ensuring normal light output, the amount of ambient light entering the display panel is minimized, thereby achieving the effect of reducing ambient light reflection. This can eliminate the need for thick circular polarizers, which helps reduce the thickness of the display panel. At the same time, the structure of the GOC anti-reflection layer is simple and can be set in multiple positions. Combined with the design of the microstructure, it can also adjust the viewing angle and other functions. Compared with the circular polarizer with a relatively fixed position, it can achieve more functions.

[0118] The following is a detailed description of the reflection reduction layer GOC:

[0119] As shown in Figures 2 to 11, the anti-reflection layer GOC includes anti-reflection units GOU that overlap with the light-emitting device LD. The anti-reflection units GOU and the light-emitting device LD can have a one-to-one correspondence, that is, one light-emitting device LD overlaps with one anti-reflection unit GOU. The light emitted by the light-emitting device LD needs to pass through the anti-reflection unit GOU that overlaps with it before it can be emitted. The thickness of the anti-reflection unit GOU will affect the brightness actually seen by the user. The smaller the thickness of the anti-reflection unit GOU, the smaller the reduction in light extraction efficiency. The thickness of the two anti-reflection units GOU that overlap with at least two light-emitting devices LD of different luminous colors can be different. The thickness of the anti-reflection unit GOU that overlaps with the light-emitting device LD with a larger degree of luminous efficiency attenuation is thinner than the thickness of the anti-reflection unit GOU that overlaps with the light-emitting device LD with a smaller degree of luminous efficiency attenuation. This is conducive to making the final light extraction efficiency of each light-emitting device LD more uniform. In addition, the thickness of the anti-reflection unit GOU in a specific area of ​​the display panel can be individually designed to improve the problem of inconsistency between local hue and the overall hue. For example, considering that the thickness of the organic layer IJP of the encapsulation layer TFE varies at the edge of the display area, rather than being of uniform thickness, the hue of the edge area is different from the light extraction efficiency of the central area surrounded by the edge area, resulting in lower hue uniformity. In this way, the thickness of the anti-reflection unit GOU located in the edge area of ​​the display area AA can be made different from that of the anti-reflection unit GOU in the central area, thereby improving the uniformity of the hue of the edge area and the hue of the central area.

[0120] The same anti-reflection layer GOC can show different hues at the same opening ratio (the ratio of pixel openings PH of different sizes), and show the same or similar hues at different opening ratios. By limiting the thickness of the anti-reflection unit GOU, display panels with different opening ratios can be applied without changing the material of the anti-reflection layer GOC, avoiding the need to constantly update the material of the anti-reflection layer GOC and reducing manufacturing difficulty.

[0121] As shown in Figures 2 to 4, in some embodiments of the present disclosure, the light-emitting device LD includes a first light-emitting device LD1 that emits red light, a second light-emitting device LD2 that emits green light, and a third light-emitting device LD3 that emits blue light; the anti-reflection unit GOU overlapping with the first light-emitting device LD1 can be defined as a first anti-reflection unit GOU1, the anti-reflection unit GOU overlapping with the second light-emitting device LD2 can be defined as a second anti-reflection unit GOU2, and the anti-reflection unit GOU overlapping with the third light-emitting device LD3 can be defined as a third anti-reflection unit GOU3.

[0122] The orthographic projection of the third light-emitting device LD3 on the driver backplane BP is larger than the orthographic projection of the first light-emitting device LD1 on the driver backplane BP, and the orthographic projection of the first light-emitting device LD1 on the driver backplane BP is larger than the orthographic projection of the second light-emitting device LD2 on the driver backplane BP. That is, the size of the third light-emitting device LD3 is larger than the size of the first light-emitting device LD1, and the size of the first light-emitting device LD1 is larger than the size of the second light-emitting device LD2. The thickness h3 of the third anti-reflection unit GOU3 is smaller than the thickness h1 of the first anti-reflection unit GOU1, and the thickness h1 of the first anti-reflection unit GOU1 is smaller than the thickness h2 of the second anti-reflection unit GOU2. When the light-emitting devices LD are of different sizes, the thickness of the anti-reflection unit GOU can compensate for the differences in luminous efficiency of different light-emitting devices LD, making the brightness more uniform.

[0123] It should be noted that the thickness of the anti-reflection unit GOU is the distance between the two points closest or farthest on the surface close to the driving back plate BP and the surface far away from the driving back plate BP in the direction perpendicular to the driving back plate BP. For example, as shown in Figure 2, if the surface of the anti-reflection unit GOU close to the driving back plate is a plane, then the thickness of the anti-reflection unit GOU is the distance between the plane and the surface of the anti-reflection unit GOU far away from the driving back plate BP; as shown in Figures 3 and 4, if the surface of the anti-reflection unit GOU close to the driving back plate BP is a curved surface, then the thickness of the anti-reflection unit GOU is the distance between the vertex of the curved surface and the surface of the anti-reflection unit GOU far away from the driving back plate BP.

[0124] In addition, the degree of absorption of ambient light by GOUs of different thicknesses also varies. Therefore, GOUs of different thicknesses can form a specific pattern in the dark state. The pattern can be graphics, text, or a combination of the two, etc., which is not specifically limited here.

[0125] Furthermore, the optical path can be adjusted by changing the morphology of the anti-reflection unit GOU to increase the front brightness or widen the viewing angle. As shown in FIG4 , in some embodiments of the present disclosure, the surface of the anti-reflection unit GOU close to the light-emitting device with which it overlaps can be a curved surface that is convex toward the light-emitting device LD, that is, a curved surface that is raised in the direction close to the driving backplane BP. This curved surface can be a spherical surface or a parabola, etc.; the surfaces of each anti-reflection unit GOU away from the light-emitting device can be located in the same plane. At the same time, the refractive index of the film layer in contact with the curved surface of the anti-reflection unit GOU is greater than the refractive index of the anti-reflection layer GOC, so that the light emitted by the light-emitting device LD diverges when passing through the curved surface. In other words, the anti-reflection unit GOU can have the effect of diverging the light of the light-emitting device LD, which is beneficial to expanding the viewing angle of the display panel and improving the color cast and the brightness attenuation curve with viewing angle (L-Decay, luminance decay).

[0126] As shown in FIG3 , in some other embodiments of the present disclosure, the surface of the anti-reflection unit GOU adjacent to the overlapping light-emitting device LD is a curved surface that is convex away from the light-emitting device LD, i.e., a curved surface that rises in a direction away from the driving backplane BP. This curved surface can be a spherical surface, a parabolic surface, or the like. The surfaces of each anti-reflection unit GOU away from the light-emitting device LD are located on the same plane. Furthermore, the refractive index of the film layer in contact with the curved surface of the anti-reflection unit GOU is greater than that of the anti-reflection layer GOC, causing light emitted from the light-emitting device LD to converge as it passes through this curved surface. In other words, the anti-reflection unit GOU can converge the light from the light-emitting device LD, thereby increasing the front brightness of the display panel.

[0127] In addition, the refractive index of the film layer in contact with the curved surface of the anti-reflection unit GOU may also be smaller than the refractive index of the anti-reflection layer GOC. Accordingly, the diverging and converging effects on light are opposite.

[0128] In the case where the surface of the anti-reflection unit GOU close to the light-emitting device LD overlapping therewith is a curved surface, the curvature of the curved surfaces of different anti-reflection units GOU can be the same. For example, the curved surfaces of different anti-reflection units GOU are all spherical surfaces with the same curvature. Of course, the curvature of the curved surfaces of different anti-reflection units GOU can be different. For example, the curved surfaces of different anti-reflection units GOU are all spherical surfaces with different curvatures. The curvature of the curved surface of a thicker anti-reflection unit GOU is different from the curvature of the curved surface of a thinner anti-reflection unit GOU.

[0129] In some embodiments, the light-emitting device LD includes a first light-emitting device LD1 that emits red light, a second light-emitting device LD2 that emits green light, and a third light-emitting device LD3 that emits blue light, the thickness h3 of the third anti-reflection unit GOU3 is less than the thickness h1 of the first anti-reflection unit GOU1, and the thickness h1 of the first anti-reflection unit GOU1 is less than the thickness h2 of the second anti-reflection unit GOU2; the curvature of the surface of the third anti-reflection unit GOU3 close to the third light-emitting device LD3 is greater than the curvature of the surface of the first anti-reflection unit GOU1 close to the first light-emitting device LD1, and the curvature of the surface of the first anti-reflection unit GOU1 close to the first light-emitting device LD1 is greater than the curvature of the surface of the second anti-reflection unit GOU2 close to the second light-emitting device LD2.

[0130] As shown in Figure 2, in some other embodiments of the present disclosure, the surface of the anti-reflection unit GOU close to the light-emitting device LD overlapping with it may be a plane, but the position in the direction perpendicular to the driving backplane BP is different, that is, it is not on the same plane. The position of the anti-reflection unit GOU close to the surface of the driving backplane BP can be limited by limiting the thickness of the film layer in contact with the anti-reflection unit GOU on the side close to the driving backplane BP; the surfaces of each anti-reflection unit GOU away from the light-emitting device LD may be located in the same plane.

[0131] Furthermore, in order to allow as much light as possible emitted by the light-emitting device LD to be emitted through the anti-reflection unit GOU, the orthographic projection of any light-emitting device LD on the driving backplane BP can be located within the orthographic projection of the anti-reflection unit GOU on the driving backplane BP that overlaps with it. In some embodiments, the boundary of the orthographic projection of any light-emitting device LD on the driving backplane BP (i.e., the boundary of the orthographic projection of the pixel opening PH on the driving backplane BP) can be located inside the boundary of the orthographic projection of the anti-reflection unit GOU on the driving backplane BP that overlaps with it, and the two boundaries can have a spacing greater than 0; at the same time, the distance between adjacent light-emitting devices LD is not less than (greater than or equal to) 10μm, and the distance between adjacent light-transmitting holes TBH is not less than (greater than or equal to) 4μm.

[0132] In addition, in some embodiments of the present disclosure, when the thicknesses of different anti-reflection units GOU are different and the surfaces of the anti-reflection units GOU close to the overlapping light-emitting devices LD are curved surfaces with the same curvature, the hue of the display panel can be adjusted by making the sizes of different light-emitting devices LD different (the sizes of the orthographic projections on the driving backplane BP are different).

[0133] The following is an exemplary description of the GOC based on its different positions:

[0134] As shown in Figures 2 to 5, the anti-reflection layer GOC is provided on the side of the touch layer TSP away from the driving backplane BP. The following example illustrates this:

[0135] As shown in Figures 2 to 4, based on the first type of implementation described above, in the first implementation of the anti-reflection layer GOC, the anti-reflection layer GOC covers the light absorbing layer BM and the insulating covering layer TOC, and the surface of the insulating covering layer TOC away from the driving back plate BP is adhered to the surface of the anti-reflection unit GOU close to the driving back plate BP; and a anti-reflection unit GOU is at least partially located in a light-transmitting hole.

[0136] The morphology of the surface of the reduction-reflection unit GOU close to the driving backplate BP can be defined by the morphology of the surface of the insulating covering layer TOC away from the driving backplate BP. For example, as shown in FIG3 , the surface of the insulating covering layer TOC away from the driving backplate BP is a curved surface convex toward the driving backplate BP, and the surface of the reduction-reflection unit GOU close to the driving backplate BP is a curved surface convex toward the driving backplate BP. As shown in FIG4 , the surface of the insulating covering layer TOC away from the driving backplate BP is a curved surface convex away from the driving backplate BP, and the surface of the reduction-reflection unit GOU close to the driving backplate BP is a curved surface convex away from the driving backplate BP. As shown in FIG2 , the insulating covering layer TOC is away from the surface plane of the driving backplate BP, and the reduction-reflection unit GOU is close to the surface plane of the driving backplate BP.

[0137] In some embodiments, the insulating covering layer TOC uses negative photoresist as an example, which has the effects of low sensitivity, development resistance, and high transmittance (Tr ≥ 98%). At 85°C, N2 / CDA (clean and dry compressed air containing nitrogen) environment, the resolution is ≥ 3.0 μm, and it is not easy to produce melt flow; the insulating covering layer TOC of different thicknesses can be formed through a halftone mask or a grayscale mask through a mask process.

[0138] As shown in Figure 5, based on the second type of implementation above, in the second implementation of the anti-reflection layer GOC, the anti-reflection layer GOC covers the light absorbing layer BM and the isolation layer SEP, and the surface of the isolation layer SEP away from the driving back plate BP is adhered to the surface of the anti-reflection unit GOU close to the driving back plate BP; and a anti-reflection unit GOU is at least partially located in a light-transmitting hole.

[0139] The morphology of the surface of the reduction-reflection unit GOU close to the driving backplate BP can be defined by the morphology of the surface of the isolation layer SEP away from the driving backplate BP. For example, if the surface of the isolation layer SEP away from the driving backplate BP is a curved surface convex toward the driving backplate BP, then the surface of the reduction-reflection unit GOU close to the driving backplate BP is a curved surface convex toward the driving backplate BP. If the surface of the isolation layer SEP away from the driving backplate BP is a curved surface convex away from the driving backplate BP, then the surface of the reduction-reflection unit GOU close to the driving backplate BP is a curved surface convex away from the driving backplate BP. If the isolation layer SEP is away from the surface plane of the driving backplate BP, then the surface plane of the reduction-reflection unit GOU close to the driving backplate BP is.

[0140] In some embodiments, the isolation layer SEP uses negative photoresist as an example, which has the effects of low sensitivity, development resistance, and high transmittance (Tr≥98%). It is not easy to produce melt flow under the environment of 85°C and N2 / CDA (clean and dry compressed air containing nitrogen). Isolation layers SEP of different thicknesses can be formed through a halftone mask or a grayscale mask through a mask process.

[0141] As shown in FIG6 to FIG11 , the GOC layer can also be provided in the encapsulation layer TFE. The GOC layer is located between the organic layer IJP and the second inorganic layer CVD2. An exemplary description is given below:

[0142] As shown in Figures 6-8 , in a third embodiment of a GOC layer, an organic layer IJP fills each pixel opening PH. The GOC layer is bonded to the surface of the organic layer IJP away from the driving backplate BP. The surface of the GOC away from the driving backplate BP is planar. The GOU is the area where the GOC layer overlaps with each pixel opening PH. A second inorganic layer CVD2 is provided on the surface of the GOC away from the driving backplate BP.

[0143] The morphology of the surface of the anti-reflection unit GOU near the driving backplate BP can be defined by the morphology of the surface of the organic layer IJP away from the driving backplate BP. For example, as shown in Figures 6 to 8, the organic layer IJP protrudes from the surface of the pixel definition layer PDL away from the driving backplate BP in the direction away from the driving backplate BP in the area corresponding to the pixel opening PH, and the surface of the organic layer IJP away from the driving backplate BP protrudes away from the driving backplate BP. In this case, the surface of the anti-reflection unit GOU near the driving backplate BP protrudes toward the driving backplate BP. If the surface of the organic layer IJP away from the driving backplate BP protrudes away from the driving backplate BP, the surface of the anti-reflection unit GOU near the driving backplate BP protrudes away from the driving backplate BP.

[0144] To achieve unequal thicknesses for different anti-reflection units (GOUs), organic layers IJP of varying thicknesses can be directly formed at different pixel openings PH through a printing process. This unequal thickness of the GOUs is achieved by the organic layers IJP. In other words, the organic layer IJP has different thicknesses in regions corresponding to at least two light-emitting devices emitting different colors, resulting in different thicknesses for the corresponding GOUs.

[0145] The third embodiment is only an exemplary description of the anti-reflection layer GOC being located in the encapsulation layer TFE. It can be combined with the touch layer TSP in the first to fourth categories or other embodiments mentioned above in any reasonable manner. No special limitation is made here. For example, Figure 6 shows the third embodiment combined with the second embodiment, Figure 7 shows the third embodiment combined with the first embodiment, and Figure 8 shows the third embodiment combined with the fourth embodiment.

[0146] As shown in FIG9-FIG11, in the fourth embodiment of the anti-reflection layer GOC, the encapsulation layer TFE may further include a limiting layer FT, the limiting layer FT covers the first inorganic layer CVD1, the anti-reflection layer GOC covers the limiting layer FT, and the organic layer IJP covers the anti-reflection layer GOC, that is, the anti-reflection layer GOC is provided between the limiting layer FT and the organic layer IJP, and the second inorganic layer CVD2 covers the organic layer IJP, wherein:

[0147] The morphology of the surface of the reducing reflective element GOU near the driving backplate BP can be defined by the morphology of the surface of the defining layer FT away from the driving backplate BP. For example, as shown in Figures 9 and 10, the defining layer FT protrudes from the surface of the pixel definition layer PDL away from the driving backplate BP in the direction away from the driving backplate BP in the area corresponding to the pixel opening PH, and the surface of the defining layer FT away from the driving backplate BP protrudes away from the driving backplate BP, so that the surface of the reducing reflective element GOU near the driving backplate BP protrudes toward the driving backplate BP. Alternatively, as shown in Figure 11, the surface of the defining layer FT away from the driving backplate BP protrudes away from the driving backplate BP, so that the surface of the reducing reflective element GOU near the driving backplate BP protrudes away from the driving backplate BP.

[0148] The limiting layer FT can be made of a negative photoresist, the material of which can be the same as the insulating cover layer TOC described above. To achieve unequal thicknesses for different anti-reflection units (GOU), a half-tone mask process can be used to directly form limiting layers FT of varying thickness at different pixel openings PH. This unequal thickness of the limiting layers FT achieves unequal thicknesses for the GOU. In other words, the limiting layer FT has different thicknesses corresponding to at least two regions of the light-emitting devices LD emitting different colors, resulting in different thicknesses for the corresponding GOUs. For the specific principles, refer to the first embodiment described above. The organic layer IJP is used to planarize the surface of the GOC away from the driving backplane BP, without further limiting the thickness and morphology of the GOC.

[0149] The fourth embodiment is merely an example of a method where the GOC layer is located within the encapsulation layer TFE. It can be combined with the touch screen layer TSP described in the first through fourth embodiments or other embodiments described above in any reasonable manner, without specific limitations. Figures 9-11 illustrate the fourth embodiment combined with the fourth embodiment, differing in the shape of the interface between the limiting layer FT and the GOU.
