[0069] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0070] 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 an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0071] 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 driving backplane or other plane parallel to the driving backplane.

[0072] The present disclosure provides a display panel. Figure 1 As shown, 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 it can be 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 used to emit light to display images, while the peripheral area WA does not emit light.

[0073] like Figure 2-Figure 11As shown, the display panel may include a driving backplane BP and a plurality of light emitting devices LD arranged on one side of the driving backplane BP, wherein:

[0074] The driving backplane BP has a driving circuit, which can drive the light-emitting device LD to emit light to display an image. 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 structure, and its material may be a hard material such as glass, or a flexible material such as polyimide. At the same time, the substrate SU may be a single-layer or multi-layer structure.

[0075] The circuit layer CL includes the above-mentioned driving circuit. For example, the driving 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 be a 7T1C, 8T1C or other structure. As long as it can drive the light-emitting device LD to emit light, its structure is not specifically limited. nTmC indicates that a pixel circuit includes n thin-film transistors (indicated by the letter "T") and m capacitors (indicated 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 may be connected in a one-to-one correspondence. Of course, the same pixel circuit may also be connected to multiple light-emitting devices LD, which is not specifically limited here.

[0076] The peripheral circuit is connected to the pixel circuit and is used to input a driving signal to the pixel circuit so as to control the light emitting device LD to emit light. The peripheral circuit may include a gate driving circuit and a light emitting control circuit, and of course, may also include other circuits. The specific structure of the peripheral circuit is not particularly limited here.

[0077] The above-mentioned circuit layer CL may include multiple thin film transistors and capacitors, wherein the thin film transistors may be top-gate or bottom-gate thin film transistors, each thin film transistor may include an active layer and a gate arranged in an overlapping manner, and the active layers of each thin film transistor may be arranged in the same semiconductor layer; or, they may be arranged in multiple semiconductor layers, and the active layers of different thin film transistors may be distributed in different semiconductor layers. The material of the semiconductor layer may be polysilicon or metal oxide, which is not specifically limited here.

[0078] Taking a 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 a 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 transistor and the capacitor, and are used to transmit driving signals. The type of driving signal and the specific pattern of each film layer depend on the specific structure of the driving circuit and are not specifically limited here.

[0079] 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.

[0080] like Figure 2-Figure 11 As shown, taking the light-emitting device LD using OLED as an example, 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 is not 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.

[0081] like Figure 2-Figure 11 As shown, the display panel may further include a pixel definition layer PDL separating the light emitting devices LD, which may be disposed on the same surface of the driving backplane BP as the light emitting devices LD. For example, the pixel definition layer PDL may be disposed on the surface of the second planar layer away from the substrate SU together with the first electrodes ANO. At the same time, the thickness of the pixel definition layer PDL is greater than the thickness of the first electrodes ANO, and covers a portion of each first electrode ANO, and has a pixel opening PH exposing each first electrode ANO, and one pixel opening PH exposes one first electrode ANO.

[0082] like Figure 2-Figure 11As shown, the light-emitting layer EL and the second electrode CAT are sequentially stacked on the first electrode ANO in the pixel opening PH. In some embodiments, the light-emitting layer EL is a discontinuous structure, and the light-emitting layers EL of each light-emitting device LD are independently spaced apart, and the light-emitting colors of different light-emitting devices LD may be different; the second electrode CAT is a continuous whole-layer structure, and the portion of the second electrode CAT located in the pixel opening PH covers the light-emitting layer EL, and the portion of the second electrode CAT located outside the pixel opening PH may also cover the pixel definition layer PDL. The sum of the thicknesses of the light-emitting layer EL and the second electrode CAT is less than the thickness of the pixel definition layer PDL, so that the second electrode CAT is recessed at the pixel opening PH.

[0083] like Figure 2-Figure 11 As shown, each light-emitting device LD is defined by the pixel definition layer PDL, wherein the range of the pixel opening PH is the range of the light-emitting device LD, that is, the shape and size of the orthographic projection of the pixel opening PH on the substrate SU are the shape and size of the orthographic projection of the light-emitting device LD on the substrate SU. At the same time, the shape of the pixel opening PH is the shape of its orthographic projection on the driving backplane BP and the substrate SU, etc., and the shape can be a polygon such as a rectangle, or a circle, etc. The definition of the shape and size of the light-emitting device LD in this article is explained based on the shape and size of the pixel opening PH. For example, the size of the light-emitting device LD is the size of its pixel opening PH.

[0084] like Figure 2-Figure 11 As shown, 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.

[0085] like Figure 2-Figure 11 As shown, 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 light-emitting 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.

[0086] There are multiple light emitting devices LD of each color, but the numbers of light emitting devices LD of different colors are 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.

[0087] like Figure 2-Figure 11As shown, in some embodiments of the present disclosure, due to the difference in the lifespan of the light-emitting layer EL of the 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 that the light-emitting efficiency is different, the size of the light-emitting device LD can be 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.

[0088] Of course, in other embodiments of the present disclosure, due to different luminescent materials, subjective preferences for pictures or 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 be different, but it is not limited to that 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, but it can be any one of the three with the largest size, the three with the same size, or other forms, so as to obtain a specific hue. That is to say, the size relationship of the light emitting device LD does not necessarily adopt a certain size relationship.

[0089] like Figure 2-Figure 11 As shown, 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 encapsulated in a thin film manner, which may include a first inorganic layer CVD1, an organic layer IJP, and a second inorganic layer CVD2, wherein:

[0090] The first inorganic layer CVD1 can cover each light emitting device LD, that is, the first inorganic layer CVD1 can 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 the thickness of the pixel definition layer PDL, and is recessed at the pixel opening PH. The material of the first inorganic layer CVD1 may include inorganic insulating materials such as silicon nitride and silicon oxide.

[0091] The organic layer IJP may be disposed on the surface of the first inorganic layer CVD1 away from the driving backplane BP, and the boundary of the organic layer IJP may be limited to the inner side of the boundary of the first inorganic layer CVD1 by the blocking dam located in the peripheral area WA. At the same time, the boundary of the orthographic projection of the organic layer IJP on the driving backplane BP may be located in the peripheral area WA, ensuring that the organic layer IJP can cover each light-emitting device LD.

[0092] The second inorganic layer CVD2 can cover the organic layer IJP and the first inorganic layer CVD1 not covered by the organic layer IJP, and can block water and oxygen intrusion through the second inorganic layer CVD2, and achieve planarization through the organic layer IJP having fluidity before curing. The material of the second inorganic layer CVD2 may include inorganic insulating materials such as silicon nitride and silicon oxide.

[0093] like Figure 2-Figure 11 As shown, the display panel may also include a touch layer TPS, which may be arranged on the side of the encapsulation layer TFE away from the driving backplane BP and is used to sense touch operations. Taking the touch layer TPS adopting a mutual capacitance touch structure as an example, the touch layer TPS may include a plurality of first touch electrodes and a plurality of second touch electrodes, each of which may be spaced apart along the row direction, and a first touch electrode may include a plurality of first electrode blocks spaced apart along the column direction and a transfer bridge connecting two adjacent first electrode blocks; each of the second touch electrodes may be spaced apart along the column direction, and a second touch electrode may include a plurality of second electrode blocks connected in series along the row direction; a transfer bridge crosses a second touch electrode and is insulated. One of the first touch electrode and the second touch electrode may be used as a transmitting electrode, and the other as a receiving electrode, and both are connected to the touch driving circuit of the peripheral area WA.

[0094] The row direction and column direction in this article are merely two directions that intersect each other, and the two directions may be perpendicular to each other or intersect at an angle other than 90°. In the drawings of the present disclosure, the row direction is horizontal and the column direction is vertical, but this is not limited thereto. Those skilled in the art will appreciate that if the display panel is rotated, the actual directions of the row direction and the column direction may change.

[0095] like Figure 2-Figure 11 As shown, for the 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, wherein the first conductive layer TMA may include the above-mentioned transfer bridge, and the specific pattern is not particularly limited here. 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 inorganic insulating materials such as silicon nitride and silicon oxide. The above-mentioned first electrode block and the 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 by the same process.

[0096] The second conductive layer TMB may be a mesh structure with a plurality of meshes, one mesh overlaps with one light emitting device LD, so that the light emitted by the light emitting device LD can be emitted from the mesh. The mesh and the light emitting device LD may be in a one-to-one correspondence; or, one mesh may overlap with a plurality of light emitting devices LD at the same time, that is, the orthographic projections of the plurality of light emitting devices LD on the driving backplane BP are located within the orthographic projection of the same mesh on the driving backplane BP, as long as the light emitted by the light emitting device LD can be emitted.

[0097] Both the first conductive layer TMA and the second conductive layer TMB may be made of conductive materials such as metals, metal oxides, alloys, etc., and both may be single-layer or multi-layer structures. Taking the second conductive layer TMB of the 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 less than that of the first conductive material layer and the third conductive material layer, and 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 material of the first conductive material layer and the third conductive material layer is titanium, titanium oxide, indium tin oxide, etc.

[0098] like Figure 2-Figure 11 As shown, 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, and the material thereof may be insulating materials such as silicon nitride and silicon oxide, which are not particularly limited herein.

[0099] Further, such as Figure 2-Figure 4 As shown, 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:

[0100] The insulating cover layer TOC may cover the second conductive layer TMB, and the second conductive layer TMB may be protected by the insulating cover layer TOC and planarized. The insulating cover layer TOC may be made of organic materials such as optical glue, for example, the insulating cover layer TOC may be made of negative photoresist, etc. The thickness of the insulating cover layer TOC is greater than any one of the first conductive layer TMA, the isolation layer SEP, and the second conductive layer TMB, so as to achieve planarization.

[0101] The light absorbing layer TBM can be arranged on the surface of the insulating cover layer TOC away from the driving backplane BP and overlap with the second conductive layer TMB. The light absorbing layer TBM can be made of a material that can absorb light, such as a black resin, to reduce the reflection of the second conductive layer TMB to ambient light. 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.

[0102] At the mesh TH of the second conductive layer TMB, the light absorbing layer TBM forms a light-transmitting hole TBH, and one light-transmitting hole TBH overlaps with one light-emitting device LD, so that the light emitted by the light-emitting device LD can be emitted from the light-transmitting hole TBH. The light-transmitting hole TBH and the light-emitting device LD can be in a one-to-one correspondence; or, one light-transmitting hole TBH can overlap with multiple light-emitting devices LD at the same time, that is, the orthographic projections of the multiple light-emitting devices LD on the driving backplane BP are located within the orthographic projection of the same light-transmitting hole TBH on the driving backplane BP, as long as the light emitted by the light-emitting device LD can be emitted.

[0103] like Figure 5 As shown, in the second embodiment of the present disclosure, the display panel further includes a light absorbing layer TBM, but does not provide an insulating cover layer TOC in the same position as in the first embodiment, wherein:

[0104] 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.

[0105] 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, i.e., a light-transmitting hole TBH. The light absorbing layer TBM can be made of a material that can absorb light, such as a black resin, to reduce the reflection of ambient light by 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 setting method of the light-transmitting hole TBH can refer to the first embodiment above, and will not be described in detail here.

[0106] like Figure 6 As shown, in the third embodiment of the present disclosure, the display panel further includes an insulating cover layer TOC and a light absorbing layer TBM, wherein:

[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 also forms an opening, that is, a light-transmitting hole TBH. The light absorbing layer TBM can be made of a material that can absorb light, such as a black resin, to reduce the reflection of ambient light by the second conductive layer TMB. The light absorbing layer TBM has a light-transmitting hole TBH that overlaps with the light-emitting device LD. The specific setting method of the light-transmitting hole TBH can refer to the first embodiment above, and will not be described in detail here.

[0108] 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 glue, and its thickness is greater than any one of the first conductive layer TMA, the isolation layer SEP, the second conductive layer TMB and the light absorbing layer TBM.

[0109] like Figure 8 As shown, in the fourth embodiment of the present disclosure, the display panel further includes an insulating cover layer TOC, but the light absorbing layer TBM mentioned above is not provided, wherein:

[0110] The insulating cover layer TOC may cover the second conductive layer TMB, and the second conductive layer TMB may be protected and planarized by the insulating cover layer TOC. The insulating cover layer TOC may be made of organic materials such as optical glue, and its thickness is greater than any one of the first conductive layer TMA, the isolation layer SEP, and the second conductive layer TMB, so as to achieve planarization.

[0111] The material of the second conductive layer TMB includes a light-absorbing conductive material. The second conductive layer TMB can be directly used to absorb ambient light, playing the role of the light-absorbing layer TBM mentioned above, so that the light-absorbing layer TBM can be omitted, which is conducive to reducing 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 is a light-absorbing conductive material. Further, the third conductive material layer can be made of a light-absorbing conductive material to avoid the first conductive material layer and the second conductive material layer reflecting ambient light. In some embodiments, the third conductive material layer can be made of molybdenum oxide, the second conductive material layer can be made of aluminum, and the first conductive material layer can be made of titanium.

[0112] The light-absorbing layer BM made of black resin and molybdenum oxide (MoO x ) The comparison of reflectivity for 550nm wavelength light at different thicknesses is shown in the following table:

[0113]

[0114] 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.

[0115] 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, the electrode blocks having light-transmitting holes overlapping with the light-emitting device LD, each electrode block may be connected to the peripheral touch drive circuit through independent wiring, and each electrode block may be located on the same layer. Compared with the mutual capacitance touch structure, one conductive layer may be reduced, 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; or, the electrode blocks may be formed by 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.

[0116] In order to reduce the reflection of ambient light, a reflection reduction layer GOC can be set on the side of the light emitting device LD away from the driving backplane BP. The reflection reduction layer GOC can be a colored photoresist or other material, which can transmit light with the same color as the light emitting device LD, and can at least absorb part of the light with a different color from the light emitting device LD; for example, 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 reflection reduction layer GOC can transmit red light, green light and blue light, and can absorb light of other colors except red light, green light and blue light. Fig.12 , Fig.12 The figure shows the transmittance of the anti-reflection layer GOC to light of different wavelengths, where G represents green light, R represents red light, and B represents blue light. Under the premise of ensuring normal light output, the ambient light entering the display panel is minimized to the greatest extent, thereby achieving the effect of reducing the reflection of ambient light, thereby eliminating the thick circular polarizer, which is beneficial to reducing the thickness of the display panel. At the same time, the anti-reflection layer GOC has a simple structure and can be set in multiple positions. Combined with the design of the microstructure, it can also play a role in adjusting the viewing angle, etc. Compared with the relatively fixed circular polarizer, it can achieve more functions.

[0117] The following is a detailed description of the reflection reduction layer GOC:

[0118] like Figure 2-Figure 11As shown, the anti-reflection layer GOC includes an anti-reflection unit GOU overlapping with the light-emitting device LD. The anti-reflection unit GOU and the light-emitting device LD may be in 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 overlapping 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 degree of reduction in light output efficiency. The thickness of the two anti-reflection units GOU overlapping with at least two light-emitting devices LD with different luminous colors can be different. The thickness of the anti-reflection unit GOU overlapping with the light-emitting device LD with a larger degree of luminous efficiency attenuation is less than the thickness of the anti-reflection unit GOU overlapping with the light-emitting device LD with a smaller degree of luminous efficiency attenuation, which is conducive to making the final light output 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 designed separately 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 equal 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. The thickness of the anti-reflection unit GOU 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.

[0119] The same anti-reflection layer GOC shows different hues at the same opening ratio (the ratio of pixel openings PH of different sizes), and shows 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.

[0120] like Figure 2-Figure 4 As shown, 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.

[0121] The orthographic projection of the third light emitting device LD3 on the driving backplane BP is larger than the orthographic projection of the first light emitting device LD1 on the driving backplane BP, and the orthographic projection of the first light emitting device LD1 on the driving backplane BP is larger than the orthographic projection of the second light emitting device LD2 on the driving 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; in the case of different sizes of the light emitting devices LD, the thickness of the anti-reflection unit GOU can compensate for the difference in luminous efficiency of different light emitting devices LD, so that the brightness is more uniform.

[0122] It should be noted that the thickness of the anti-reflection unit GOU is the distance between the closest or farthest points of its surface close to the driving back plate BP and its surface far away from the driving back plate BP in the direction perpendicular to the driving back plate BP. For example, Figure 2 As shown in FIG. 1 , if the surface of the anti-reflection unit GOU close to the driving back plate is a plane, the thickness of the anti-reflection unit GOU is the distance between the plane and the surface of the anti-reflection unit GOU away from the driving back plate BP; Figure 3 and Figure 4 As shown, if the anti-reflection unit GOU is close to the curved surface of the driving back plate BP, 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 away from the driving back plate BP.

[0123] In addition, the degree of absorption of ambient light by the anti-reflection units GOU of different thicknesses also varies. Therefore, a specific pattern can be formed in the dark state by the anti-reflection units GOU of different thicknesses. The pattern can be graphics, text, or a combination of the two, etc., which is not specifically limited here.

[0124] Furthermore, the light path can be adjusted by changing the morphology of the GOU to increase the front brightness or the viewing angle, such as Figure 4 As shown, in some embodiments of the present disclosure, the surface of the anti-reflection unit GOU close to the light-emitting device overlapping with it can be a curved surface convex toward the light-emitting device LD, that is, a curved surface convex in the direction close to the driving backplane BP, and the 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, that is, the anti-reflection unit GOU can play the effect of diverging the light of the light-emitting device LD, which is beneficial to expand the viewing angle of the display panel and improve the color deviation and the brightness attenuation curve (L-Decay, luminance decay) with the viewing angle.

[0125] like Figure 3 As shown, in some other embodiments of the present disclosure, the surface of the anti-reflection unit GOU close to the light-emitting device LD overlapped therewith is a curved surface convex away from the light-emitting device LD, that is, a curved surface convex in the direction away from the driving back plate BP, and the 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 LD are 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 converges when passing through the curved surface, that is, the anti-reflection unit GOU can play the effect of converging the light of the light-emitting device LD, which is conducive to increasing the front brightness of the display panel.

[0126] 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 divergence and convergence effects on light are opposite.

[0127] 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 curvatures of the curved surfaces of different anti-reflection units GOU may 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 curvatures of the curved surfaces of different anti-reflection units GOU may be different, for example, the curved surfaces of different anti-reflection units GOU are all spherical surfaces with different curvatures, and the curvature of the curved surface of the anti-reflection unit GOU with a larger thickness is different from the curvature of the curved surface of the anti-reflection unit GOU with a smaller thickness.

[0128] 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.

[0129] like Figure 2As shown, 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 positions in the direction perpendicular to the driving backplane BP are different, that is, they are not on the same plane, and 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.

[0130] Furthermore, in order to make the light emitted by the light emitting device LD to be emitted through the anti-reflection unit GOU as much as possible, 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 overlapping with it on the driving backplane BP. 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 overlapping with it on the driving backplane BP, 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.

[0131] 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).

[0132] The following is an exemplary description of the GOC based on the different positions of the GOC:

[0133] like Figure 2-Figure 5 As shown, the anti-reflection layer GOC is arranged on the side of the touch layer TSP away from the driving backplane BP, and the following example is used for explanation:

[0134] like Figure 2-Figure 4 As shown, based on the first type of implementation above, in the first implementation of the reflection reduction layer GOC, the reflection reduction 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 reflection reduction unit GOU close to the driving back plate BP; and a reflection reduction unit GOU is at least partially located in a light-transmitting hole.

[0135] The morphology of the surface of the down-reflection unit GOU close to the driving back plate BP can be defined by the morphology of the surface of the insulating cover layer TOC away from the driving back plate BP, for example, Figure 3As shown, the surface of the insulating cover layer TOC away from the driving back plate BP is a curved surface convex toward the driving back plate BP, and the surface of the anti-reflection unit GOU close to the driving back plate BP is a curved surface convex toward the driving back plate BP. Figure 4 As shown, the surface of the insulating cover layer TOC away from the driving back plate BP is a curved surface convexly facing away from the driving back plate BP, and the surface of the anti-reflection reduction unit GOU close to the driving back plate BP is a curved surface convexly facing away from the driving back plate BP. Figure 2 As shown, the insulating cover layer TOC is far away from the surface plane of the driving back plate BP, and the down-reflection unit GOU is close to the surface plane of the driving back plate BP.

[0136] In some embodiments, the insulating cover layer TOC is made of negative photoresist, which has the effects of low sensitivity, resistance to development, and high transmittance (Tr≥98%). 2 In the environment of / CDA (clean and dry compressed air containing nitrogen), the resolution is ≥3.0μm and it is not easy to produce melt flow; the insulating covering layer TOC of different thickness can be formed through the mask process through a halftone mask or a grayscale mask.

[0137] like Figure 5 As shown, based on the second type of implementation above, in the second implementation of the reflection reduction layer GOC, the reflection reduction 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 bonded with the surface of the reflection reduction unit GOU close to the driving back plate BP; and a reflection reduction unit GOU is at least partially located in a light-transmitting hole.

[0138] The morphology of the surface of the reduction reflection unit GOU close to the driving back plate BP can be limited by the morphology of the surface of the isolation layer SEP away from the driving back plate BP. For example, if the surface of the isolation layer SEP away from the driving back plate BP is a curved surface convex toward the driving back plate BP, then the surface of the reduction reflection unit GOU close to the driving back plate BP is a curved surface convex toward the driving back plate BP. If the surface of the isolation layer SEP away from the driving back plate BP is a curved surface convex away from the driving back plate BP, then the surface of the reduction reflection unit GOU close to the driving back plate BP is a curved surface convex away from the driving back plate BP. If the isolation layer SEP is away from the surface plane of the driving back plate BP, then the surface plane of the reduction reflection unit GOU close to the driving back plate BP.

[0139] In some embodiments, the isolation layer SEP is made of negative photoresist, which has the effects of low sensitivity, development resistance, and high transmittance (Tr≥98%). 2 In the environment of / CDA (clean and dry compressed air containing nitrogen), it is not easy to produce melt flow; an isolation layer SEP of unequal thickness can be formed through a halftone mask or a grayscale mask through a mask process.

[0140] like Figure 6-Figure 11 As shown, the reflection reducing layer GOC can also be arranged in the encapsulation layer TFE, and the reflection reducing layer GOC is located between the organic layer IJP and the second inorganic layer CVD2, as exemplified below:

[0141] like Figure 6-Figure 8 As shown, in the third embodiment of the anti-reflection layer GOC, the organic layer IJP fills each pixel opening PH. The anti-reflection layer GOC is attached to the surface of the organic layer IJP away from the driving back plate BP, the surface of the anti-reflection layer GOC away from the driving back plate BP is a plane, and the anti-reflection unit GOU is the area where the anti-reflection layer GOC overlaps with each pixel opening PH; the second inorganic layer CVD2 is arranged on the surface of the anti-reflection layer GOC away from the driving back plate BP.

[0142] The morphology of the surface of the down-reflection unit GOU close to the driving back plate BP can be determined by the morphology of the surface of the organic layer IJP away from the driving back plate BP, for example, Figure 6-Figure 8 As shown, the organic layer IJP protrudes from the surface of the pixel definition layer PDL away from the driving backplane BP in the area corresponding to the pixel opening PH in the direction away from the driving backplane BP, and the surface of the organic layer IJP away from the driving backplane BP protrudes away from the driving backplane BP, and the surface of the anti-reflection unit GOU close to the driving backplane BP protrudes toward the driving backplane BP. The surface of the organic layer IJP away from the driving backplane BP protrudes away from the driving backplane BP, and the surface of the anti-reflection unit GOU close to the driving backplane BP protrudes away from the driving backplane BP.

[0143] In order to achieve different thicknesses of different anti-reflection units GOU, organic layers IJP of different thicknesses can be directly formed at different pixel openings PH through a printing process, and different thicknesses of the anti-reflection units GOU are achieved through the organic layers IJP of different thicknesses. That is, the thicknesses of the organic layer IJP corresponding to the regions of at least two light-emitting devices with different luminous colors are different, so that the thicknesses of the corresponding anti-reflection units GOU are different.

[0144] The third embodiment is only an exemplary description of the anti-reflection layer GOC being located in the encapsulation layer TFE, which can be combined with the touch layer TSP in the first to fourth categories or other embodiments described above in any reasonable manner, and is not specifically limited here. For example, Figure 6 The third implementation mode is combined with the second implementation mode. Figure 7 The third implementation mode is combined with the first implementation mode. Figure 8 The third implementation mode is combined with the fourth implementation mode.

[0145] like Figure 9-11As shown, 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 arranged between the limiting layer FT and the organic layer IJP, and the second inorganic layer CVD2 covers the organic layer IJP, wherein:

[0146] The morphology of the surface of the down-reflection unit GOU close to the driving back plate BP can be limited by the morphology of the surface of the limiting layer FT away from the driving back plate BP, for example, Fig. 9 and Fig.10 As shown, the limiting layer FT protrudes from the surface of the pixel definition layer PDL away from the driving back plate BP in the area corresponding to the pixel opening PH in the direction away from the driving back plate BP, and the surface of the limiting layer FT away from the driving back plate BP protrudes away from the driving back plate BP, and the surface of the anti-reflection unit GOU close to the driving back plate BP protrudes toward the driving back plate BP. Or, as Fig.11 As shown, the surface of the limiting layer FT away from the driving back plate BP protrudes away from the driving back plate BP, and the surface of the anti-reflection unit GOU close to the driving back plate BP protrudes away from the driving back plate BP.

[0147] The limiting layer FT may be made of negative photoresist, and its material may be the same as the insulating cover layer TOC mentioned above. In order to achieve unequal thickness of different anti-reflection units GOU, a limiting layer FT of unequal thickness may be directly formed at different pixel openings PH through a half-tone mask process, and the unequal thickness of the anti-reflection units GOU is achieved through the limiting layer FT of unequal thickness. In other words, the thickness of the limiting layer FT corresponding to the region of at least two light-emitting devices LD with different luminous colors is different, so that the thickness of the corresponding anti-reflection units GOU is different. The specific principle can be referred to the first embodiment mentioned above. The organic layer IJP is used to achieve planarization on the surface of the anti-reflection layer GOC away from the driving backplane BP, and no longer limits the thickness and morphology of the anti-reflection layer GOC.

[0148] The fourth implementation is only an exemplary description of the anti-reflection layer GOC being located in the encapsulation layer TFE, which can be combined with the touch layer TSP in the first to fourth categories or other implementations described above in any reasonable manner and is not particularly limited here. Figure 9-11 All of them are combinations of the fourth embodiment and the fourth type of embodiment, the difference being that the shapes of the interfaces between the limiting layer FT and the reflection reduction unit GOU are different.
