[0027] However, the exemplary embodiments may be embodied in various forms and should not be understood as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. Since the same reference numerals in the drawings represent the same or similar structures, detailed descriptions will be omitted. Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0028] The terms "a," "one," "the," "said," and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprise" and "have" are used to denote an open inclusion and mean that other elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first," "second," "third," etc. are used as indicative marks only and do not imply a quantitative limitation on the subject.

[0029] In this specification, "overlapping" of A and B means that there is an overlapping area in the orthogonal projection of A and B in a plane parallel to the driving backplate or other driving backplates, and it is understood that A and B may be in direct contact or may be spaced apart in a direction perpendicular to the driving backplate.

[0030] In the related art, a silicon-based OLED display panel includes a driving backplate, a light-emitting functional layer, and a color film layer, where the light-emitting functional layer is provided on one side of the driving backplate and includes a plurality of light-emitting units, and each light-emitting unit includes a first electrode (anode), a light-emitting layer, and a second electrode (cathode) stacked in sequence away from the driving backplate, and the light-emitting layer can be driven to emit light by applying an electric signal to the first electrode and the second electrode, and the specific light-emitting principle of the light-emitting unit is omitted here.

[0031] Furthermore, the light-emitting layers of each light-emitting unit can be directly deposited using a fine mask plate (FMM), and the light-emitting layers of each light-emitting unit are distributed at intervals and emit light independently, enabling color display. However, due to the constraints of the fine mask plate manufacturing process, it is difficult to achieve a high PPI (pixel density). Therefore, color display can also be achieved using a color film using monochromatic or white light. That is, each light-emitting unit shares the same continuous light-emitting layer, and the light-emitting layer can emit white light or other monochromatic light. The color film layer has multiple filter sections corresponding to the light-emitting units one-to-one. Each light-emitting unit corresponding to one filter section can constitute one subpixel, and multiple subpixels constitute one pixel. Different filter sections can transmit different colors of light, and different subpixels can emit different colors. The same pixel can contain multiple subpixels of different colors; for example, one pixel can contain three subpixels emitting red, green, and blue, respectively. This allows color display using multiple pixels.

[0032] To enhance the brightness of the display panel, multiple lenses may be provided on the color film layer away from the driving backplate. Each lens can overlap a light-emitting unit, converging the relatively divergent light emitted by the light-emitting unit through the lens, thereby achieving light concentration and increasing brightness. However, this convergence of light narrows the light output range of the display panel and reduces the viewing angle. Furthermore, the lens surface is usually arcuate, which causes light to converge toward the optical axis (perpendicular to the driving backplate), narrowing the range of high brightness and significantly limiting the user's viewing angle.

[0033] An embodiment of the present disclosure provides a display panel, as shown in FIGS. 1 and 4 to 9, which may include a driving backplate BP, a light-emitting unit LD, a color film layer CFL, and a lens layer LL, wherein: The number of light emitting units LD is plural, and they are distributed in an array on one side of the driving back plate BP.

[0034] The color film layer CFL is provided on the side of the light-emitting unit LD that is farther from the driving back plate BP, and includes a plurality of filter sections CF, each of which overlaps with one light-emitting unit LD, and the filter sections CF include a first filter section CF1, and the filter sections CF include an intermediate area MA and an edge area EA that includes the outer periphery of the intermediate area MA.

[0035] The lens layer LL has a color film layer CFL disposed on a surface away from the driving backplate BP, and includes a plurality of lenses LENS distributed in an array, one lens LENS overlapping one filter section CF, the lens LENS including a top surface TS and a side surface SS surrounding the edge of the top surface TS, the side surface SS being a curved surface contracting toward the top surface TS, the lens LENS including a first lens LENS1 overlapping the first filter section CF1, and in the first lens LENS1 and the first filter section CF1 overlapping it, an intermediate region MA overlaps the top surface TS, and the side surface SS overlaps the edge region EA.

[0036] In a cross section of the lens LENS and the filter part CF overlapping it perpendicular to the drive back plate BP, the curvature of any point on the contour of the top surface TS is smaller than the curvature of any point on the contour of the side surface SS, and the curvature difference between two points opposing each other in a direction perpendicular to the drive back plate BP in the contours of the intermediate region MA and the top surface TS is the central curvature difference between the lens LENS and the filter part CF overlapping it, and the curvature difference between two points opposing each other in a direction perpendicular to the drive back plate BP in the contours of the side surface SS and the edge region EA is the edge curvature difference between the lens LENS and the filter part CF overlapping it, and the central curvature difference is smaller than the edge curvature difference.

[0037] In the display panel according to the embodiment of the present disclosure, the surface of the lens LENS is divided into at least a side surface SS and a top surface TS, and the curvatures of the side surface SS and the top surface TS are limited. That is, in a cross section of the lens LENS and the filter unit CF overlapping it perpendicular to the driving backplate BP, the curvature of the contour of the top surface TS at any point is smaller than the curvature of the contour of the side surface SS at any point. This makes the top surface TS gentler than the side surface SS, and the light converging effect of the top surface TS is weaker than that of the side surface SS. This allows light emitted from a large angle through the side surface SS to be converged, thereby increasing the front brightness. The top surface TS also prevents light from being overly concentrated and the high-brightness area from being too narrow, which is advantageous for increasing the viewing angle. This allows the viewing angle to be maximized while increasing brightness, i.e., achieving both brightness and viewing angle.

[0038] Next, a detailed description will be given of the configuration in which the display panel of the present disclosure realizes the display function. The display panel may include a display area and a peripheral area located outside the display area and surrounding the display area. The driving backplate BP is used to form a driving circuit for driving the light emitting units LD to emit light, and the driving circuit may include pixel circuits and peripheral circuits, where: The number of pixel circuits and light-emitting units LD may be multiple, with at least some of the pixel circuits located within the display area. The pixel circuits may be 2T1C, 4T1C, or other types of pixel circuits, as long as they are driven to emit light from the light-emitting units LD; their structure is not particularly limited here. The number of pixel circuits is the same as the number of light-emitting units LD, and they are connected to the light-emitting units LD in one-to-one correspondence to individually control the emission of each light-emitting unit LD. Here, nTmC indicates that the pixel circuit includes n transistors (represented by the letter "T") and m capacitors (represented by the letter "C"). Of course, the same pixel circuit can drive multiple light-emitting units LD.

[0039] The peripheral circuit is located in the peripheral region and connected to the pixel circuit. The peripheral circuit may include a light emitting control circuit, a gate driving circuit, a source driving circuit, etc., and may also include a power circuit connected to the light emitting unit LD for inputting a power signal to the light emitting unit LD. Thus, the peripheral circuit can directly input a signal to the light emitting unit LD via the pixel circuit, causing the light emitting unit LD to emit light.

[0040] 1 to 3 , in some embodiments of the present disclosure, the driving backplate BP includes a substrate SU, for example, a silicon substrate, and the driving circuits can be formed on the silicon substrate by a semiconductor process. For example, both the pixel circuit and the peripheral circuit can include multiple transistors. A well region WL can be formed in the silicon substrate by a doping process, and the well region WL has two doping regions DR spaced apart. Taking one well region WL as an example, a gate GATE is provided on one side of the driving backplate BP. The orthogonal projection of the gate GATE onto the driving backplate BP is located between the two doping regions DR. The well region WL and the gate GATE can form a transistor, and the doping regions DR of the well region WL are the first and second poles of the transistor, respectively. The well region WL between the two doping regions DR is the channel region of the transistor.

[0041] The driving backplate BP includes at least one wiring layer TL provided on one side of the substrate SU and a flat layer PLN covering the wiring layer TL, and the at least one wiring layer TL is connected to each doping region DR.

[0042] 2, the number of wiring layers TL is two, and they are located within the flat layer PLN, and the wiring layer TL includes, for example, a first wiring layer TL1 provided on one side of the substrate SU, with a part of the flat layer PLN provided between the first wiring layer TL1 and the substrate SU, and a second wiring layer TL2. The second wiring layer TL2 is provided on the side of the first wiring layer TL1 away from the substrate SU, and is separated from the first wiring layer TL1 by a part of the flat layer PLN, and at least a part of the second wiring layer TL2 is connected to the first wiring layer TL1.

[0043] Each wiring layer TL can be formed by sputtering. The material of the planar layer PLN can be silicon oxide, silicon oxynitride, or silicon nitride, and can be formed layer by layer by multiple deposition and polishing processes. In other words, the planar layer PLN can be stacked from multiple insulating film layers, and multiple film layers are not distinguished in the drawings.

[0044] 2 and 3, the light-emitting units LD are distributed in an array on one side of the driving backplate BP, and are provided, for example, on the surface of the flat layer PLN that is remote from the substrate SU. Each light-emitting unit LD may include a first electrode ANO, a second electrode CAT, and a light-emitting layer EL located between the first electrode ANO and the second electrode CAT, and the first electrode ANO and the second electrode CAT are both connected to the wiring layer TL. The light emission of the light-emitting layer EL can be driven by applying a driving signal to the first electrode ANO and a power signal to the second electrode CAT via the driving backplate BP.

[0045] To prevent crosstalk between adjacent light-emitting units LD, each light-emitting unit LD can be separated by a pixel definition layer PDL to define the extent of the light-emitting unit LD.

[0046] In some embodiments of the present disclosure, the first electrodes ANO are provided on one side of the driving backplate BP, for example, on the surface of the planar layer PLN away from the substrate SU, as shown in Figures 1 to 3. Each of the first electrodes ANO is located in the display area and connected to a pixel circuit, and one of the first electrodes ANO is connected to the pixel circuit.

[0047] The first electrode ANO may have a single-layer or multi-layer structure, and its material is not particularly limited herein. For example, the first electrode ANO may include a first conductive layer, a second conductive layer, and a third conductive layer stacked in sequence in a direction away from the driving backplate BP, where the first conductive layer and the third conductive layer have a higher corrosion resistance than the second conductive layer. For example, the second conductive layer may be made of aluminum, and the first conductive layer and the third conductive layer may be made of titanium. The stacked first conductive layer, the second conductive layer, and the third conductive layer may also be covered with a fourth conductive layer such as indium tin oxide.

[0048] 1 to 3, the pixel definition layer PDL and the first electrodes ANO are provided on the same surface of the drive backplate BP. For example, the pixel definition layer PDL is located on the surface where the planar layer PLN is away from the substrate SU, and the pixel definition layer PDL exposes each of the first electrodes ANO. Specifically, the pixel definition layer PDL may be provided with a plurality of pixel openings that expose each of the first electrodes ANO.

[0049] The orthogonal projection of any pixel aperture onto the driving backplate BP is located within the exposed first electrode ANO, i.e. the pixel aperture is not larger than the exposed first electrode ANO, for example the boundary of the pixel aperture is located inside the boundary of the exposed first electrode ANO, i.e. the area of ​​the pixel aperture is smaller than the area of ​​the exposed first electrode ANO, so that the pixel definition layer PDL covers the edges of the first electrode ANO.

[0050] As shown in FIG. 11, the shape of the pixel opening may be a polygon such as a rectangle, pentagon, or hexagon, but is not necessarily a regular polygon. The shape of the pixel opening may be other shapes such as an ellipse, and is not particularly limited here.

[0051] 1 to 3, the light-emitting layer EL covers the pixel definition layer PDL and the first electrode ANO, and the region where the light-emitting layer EL and the first electrode ANO are stacked is used to form the light-emitting unit LD. That is, each light-emitting unit LD can share the same light-emitting layer EL, and the portions of the light-emitting layer EL stacked on different first electrodes ANO belong to different light-emitting units LD. Furthermore, since each light-emitting unit LD shares the light-emitting layer EL, the emission colors of the different light-emitting units LD are the same.

[0052] In some embodiments of the present disclosure, as shown in FIGS. 1 and 10 , a light-emitting unit LD may include multiple series light-emitting devices, each including a first electrode ANO, a second electrode CAT, and multiple light-emitting sub-layers OLP between the first electrode ANO and the second electrode CAT, and each light-emitting device of the same light-emitting unit LD may share the same first electrode ANO and the same second electrode CAT, that is, the same light-emitting unit LD may only have one first electrode ANO and one second electrode CAT.

[0053] 1 and 10, the light-emitting layer EL includes a hole-injection layer HIL1, multiple light-emitting sublayers OLP, and an electron-injection layer EIL. The light-emitting sublayers OLP are disposed between the hole-injection layer HIL1 and the electron-injection layer EIL and are connected in series away from the driving backplate BP. Two adjacent light-emitting sublayers OLP can be connected in series via a charge-generation layer CGL located between them. When an electrical signal is applied to the first electrode ANO and the second electrode CAT, each light-emitting sublayer OLP can emit light, and different light-emitting sublayers OLP can be used to emit light of different colors.

[0054] Furthermore, as shown in FIG. 10, any of the light-emitting sub-layers OLP may include at least a hole transport layer HTL, a light-emitting material layer EML, and an electron transport layer ETL, which are distributed in a direction away from the driving backplate BP. The specific light-emitting principle is not described here. Here, The number of hole injection layers HIL, hole transport layers HTL, electron transport layers ETL, and electron injection layers EIL is not particularly limited here, and adjacent light-emitting sub-layers OLP can share one or more of the hole injection layer HIL, hole transport layer HTL, electron transport layer ETL, and electron injection layer EIL. At the same time, a charge generation layer CGL can be provided between at least two adjacent light-emitting sub-layers OLP to connect the two light-emitting sub-layers OLP in series.

[0055] In some embodiments of the present disclosure, the light-emitting layer EL can include two light-emitting sublayers OLP of different colors, i.e., a first light-emitting sublayer that simultaneously emits red and green light and a second light-emitting sublayer that emits blue light, and the first and second light-emitting sublayers OLP can simultaneously emit light so that the light-emitting layer EL emits white light, as shown in Figure 10. Here, the first light-emitting sublayer has two light-emitting material layers EML, a red light-emitting material layer R-EML and a green light-emitting material layer G-EML. Specifically, the first light-emitting sublayer can include a hole-transport layer HTL1, a light-emitting material layer R-EML, a light-emitting material layer G-EML, and an electron-transport layer ETL2, which are sequentially stacked on a hole-injection layer HIL1 in a direction away from the driving backplate BP.

[0056] A charge generation layer CGL may be provided on the surface of the first light-emitting sublayer away from the driving backplate BP. The second light-emitting sublayer is provided on the surface of the charge generation layer CGL away from the driving backplate BP and connects the first and second light-emitting sublayers in series. The second light-emitting sublayer includes a hole injection layer HIL2, a hole transport layer HTL2, a hole transport layer HTL3, a blue light-emitting material layer B-EML, a hole barrier layer HBL, and an electron transport layer ETL2, which are sequentially stacked on the side of the charge generation layer CGL away from the driving backplate BP in the direction away from the driving backplate BP. The electron injection layer EIL is provided on the surface of the electron transport layer ETL2 away from the driving backplate BP. A second electrode CAT is provided on the surface of the electron injection layer EIL away from the driving backplate BP.

[0057] The above-described light-emitting layer EL structure is merely an illustrative example and does not constitute a limitation on the film layer. The number of light-emitting sub-layers OLP may be greater, or may include only one light-emitting sub-layer OLP, as long as it can achieve color display in accordance with the color film layer.

[0058] As shown in Figures 1 to 3, the second electrode CAT covers the light-emitting layer EL, and the orthogonal projection of the second electrode CAT onto the driving backplate BP covers the display area and extends into the peripheral area. Each light-emitting unit LD can share the same second electrode CAT. The light emission of the light-emitting layer EL can be controlled by controlling the voltage of the power supply signal input to the second electrode CAT and the voltage of the driving signal input to the first electrode ANO.

[0059] 1 and 4, the color film layer CFL has a second electrode CAT disposed on the side away from the driving backplate BP and includes multiple filter elements CF. Each filter element CF overlaps with one light-emitting unit LD. That is, the orthogonal projection of each filter element CF onto the driving backplate BP at least partially overlaps with one pixel opening of one pixel definition layer PDL. For example, each light-emitting unit LD and each filter element CF overlap one another in a direction perpendicular to the driving backplate BP. The filter elements CF can be divided into multiple sections, each of which includes at least a middle area MA and an edge area EA surrounding the middle area MA, and the edge area EA is integral with the middle area MA.

[0060] The filter section CF can absorb a portion of the light and transmit only monochromatic light such as red, blue, or yellow. Each filter section CF includes at least a first filter section CF1, a second filter section CF2, and a third filter section CF3 of different colors. For example, the first filter section CF1 is used to transmit blue light, the second filter section CF2 is used to transmit red light, and the third filter section CF3 is used to transmit green light. The light emitted by each light-emitting unit LD is filtered by the filter section CF to obtain monochromatic light of different colors, thereby realizing a color display.

[0061] In addition, the color film layer CFL can be provided with a light-blocking structure that limits the range of light. This light-blocking structure may be a partition that separates the black material of the filter section CF, or the edge areas EA of two adjacent filter sections CF can be stacked in a direction away from the drive backplate BP, and since the translucent colors of the stacked edge areas EA are different, a light-blocking effect can be achieved.

[0062] The width of the laminated region is the laminated width Wp of two adjacent filter members CF. For example, the laminated width Wp may be 0.5 μm to 0.9 μm, such as 0.5 μm, 0.6 μm, 0.7 μm, 0.8 μm, or 0.9 μm. The laminated width Wp between the first filter member CF1 and the second filter member CF2, the laminated width Wp between the second filter member CF2 and the third filter member CF3, and the laminated width Wp between the first filter member CF1 and the third filter member CF2 may be the same or different.

[0063] 1, 4, 7, and 8, in some embodiments of the present disclosure, the first filter portion CF1 is provided adjacent to the second filter portion CF2 and the third filter portion CF3 at the same time, and is located between the second filter portion CF2 and the third filter portion CF3. At the same time, the second filter portion CF2 is provided adjacent to the other third filter portion CF3 on the side away from the first filter portion CF1. There are no other filter portions CF between the adjacent filter portions CF.

[0064] In the adjacent first filter portion CF1 and second filter portion CF2, a portion of the edge region EA of the second filter portion CF2 is stacked on the side of the edge region EA of the first filter portion CF1 that is farther from the drive backplate BP. In the adjacent third filter portion CF3 and second filter portion CF2, a portion of the edge region EA of the third filter portion CF3 that is farther from the surface of the drive backplate BP curves in a direction away from the drive backplate BP, and the edge region EA of the second filter portion CF2 is stacked on the side farther from the drive backplate BP. At the same time, in the adjacent third filter portion CF3 and first filter portion CF1, the edge region EA of the third filter portion CF3 is stacked on the side of the edge region EA of the first filter portion CF1 that is closer to the drive backplate BP.

[0065] As shown in Figure 4, when forming the filter member CF of this embodiment, the second filter member CF2 can be formed first using a mask process so that the second filter member CF2 does not cover the other filter members CF, then the third filter member CF3 can be formed so that the third filter member CF3 can cover a partial region of the second filter member CF2, and finally the first filter member CF1 is formed so that it simultaneously covers partial regions of the second filter member CF2 and the third filter member CF3, thereby realizing the above-mentioned stacked installation.

[0066] According to the stacking arrangement of this embodiment, the surface of the middle region MA of the second filter portion CF2 away from the drive backplate BP is parallel to the drive backplate BP, and the surface of the edge region EA of the second filter portion CF2 away from the drive backplate BP can be curved in a direction toward the drive backplate BP. The sidewalls of the second filter portion CF2 are expandable in a direction away from the drive backplate BP. A portion of the surface of the third filter portion CF3 away from the drive backplate BP curves in a direction toward the drive backplate BP, and a portion of the edge region EA of the adjacent first filter portion CF2 is stacked on the side away from the drive backplate BP of the edge region EA of the adjacent third filter portion CF3, and a portion of the surface of the third filter portion CF3 away from the drive backplate BP curves in a direction away from the drive backplate BP, and the edge region EA of the adjacent second filter portion CF2 is stacked on the side away from the drive backplate BP.

[0067] In some embodiments of the present disclosure, as shown in Figures 1 and 7, the color film layer CFL may also include a color film planarizing layer PLNC, which can cover each filter element CF. The surface of the color film planarizing layer PLNC remote from the driving backplate BP is flat, achieving planarization. The color film planarizing layer PLNC may be made of a transparent material such as optical rubber, and the material is not particularly limited herein as long as it is transparent. A lens layer LL may be provided on the surface of the color film planarizing layer PLNC remote from the driving backplate BP.

[0068] In some embodiments of the present disclosure, the thickness of the filter CF may be 1.2 μm to 1.4 μm, for example, 1.2 μm, 1.3 μm, and 1.4 μm. Of course, the thickness of the filter member CF may be different depending on the color.

[0069] 1, 5, 7, and 8, the lens layer LL is provided on the surface of the color film layer CFL away from the driving backplate BP and may include a plurality of lenses LENS distributed in an array, where the lens LENS is a convex lens and may include a top surface TS and a side surface SS surrounding the edge of the top surface TS, where the orthogonal projection of the side surface SS onto the driving backplate BP is annular, and this annular shape is surrounded outside the orthogonal projection of the top surface TS onto the driving backplate BP. The top surface TS may smoothly transition to the side surface SS.

[0070] The side surface SS is a curved surface that gradually narrows toward the top surface TS, and this curved surface may be spherical, ellipsoidal, or parabolic. One lens LENS can overlap one filter section CF so as to overlap one light-emitting unit LD. There may be multiple lenses LENS, each overlapping one filter section CF. Furthermore, the top surface TS of the lens LENS may overlap the middle region MA of the filter section CF it overlaps, and the side surface of the lens LENS may overlap the edge region EA of the filter section CF it overlaps. At least a portion of the light emitted by the light-emitting unit LD can pass through the filter section CF it overlaps and then through the lens LENS it overlaps, which can collect the light and increase brightness.

[0071] The lenses LENS are spaced apart, and the distance between adjacent lenses LENS can be defined as a lens pitch Wl. The lens pitch Wl of any two adjacent lenses LENS may be equal. For example, the lens pitch Wl may be 0.3 μm to 0.5 μm, such as 0.3 μm, 0.4 μm, and 0.5 μm.

[0072] 1, 5, 7, and 8, in some embodiments of the present disclosure, the lens layer LL may further include a substrate LB, in which the color film layer CFL is disposed on the side remote from the driving backplate BP, and each lens LENS is disposed on the surface of the substrate LB remote from the driving backplate BP, and the substrate LB may be made of a transparent material, which may be the same material as the lens LENS, and the lens LENS may be integral with the substrate LB. Of course, the substrate LB and the lens LENS may each have an independent structure.

[0073] As shown in Figures 1, 5, 7 and 8, in some embodiments of the present disclosure, each lens LENS may include a first lens LENS1 overlapping a first filter portion CF1, a second lens LENS2 overlapping a second filter portion CF2, and a third lens LENS3 overlapping a third filter portion CF3.

[0074] As shown in FIGS. 1 and 7 , in some embodiments of the present disclosure, the display panel of the present disclosure may further include a package layer TFE, which may be located on the side of the second electrode CAT away from the driving backplate BP and between the color film layer CFL and the second electrode CAT to block corrosion from external water and oxygen. The package layer TFE may have a single-layer or multi-layer structure. For example, the package layer TFE may include a first package sublayer, a second package sublayer, and a third package sublayer stacked in sequence away from the driving backplate BP. Here, the first and second package sublayers may be made of inorganic insulating materials such as silicon nitride or silicon oxide. The second package sublayer may be formed using an ALD (Atomic Layer Deposition) process, and the third package sublayer may be made of an organic material that can be formed using an MLD (Molecular Layer Deposition) process. Of course, the package layer TFE may also have other structures; the structure of the package layer TFE is not particularly limited herein.

[0075] 1 and 7 , in some embodiments of the present disclosure, the display panel may further include an adhesive layer OC and a transparent cover CG, and the transparent cover CG may be attached to the side of the lens layer LL away from the driving backplate BP via the adhesive layer OC. For example, the adhesive layer OC may be coated on each lens LENS, and the surface of the adhesive layer OC away from the driving backplate BP may be flat, thereby achieving planarization. At the same time, the refractive index of the adhesive layer OC is smaller than that of the lens LENS, ensuring that the refraction angle of a light ray propagating from the lens LENS to the adhesive layer OC is greater than the incident angle, thereby converging the light ray.

[0076] The transparent cover CG can be attached to the surface away from the driving backplate BP by the adhesive layer OC. The transparent cover CG may have a single layer or multi-layer structure with materials not particularly limited here.

[0077] Based on the display panel of the above embodiment, in order to increase the brightness while avoiding a narrow viewing angle, the shape and size of the lens LENS and the filter unit CF can be limited, and specific methods will be described below: First, as shown in Figures 1, 5, 7, and 8, the top surface TS of the lens LENS can be made gentler than the side surface SS, i.e., the degree of curvature of the top surface TS is less than the degree of curvature of the side surface SS. This weakens the converging effect of the top surface TS on light rays, reduces the brightness difference of the light rays emitted from the top surface TS, increases the high-brightness area, and widens the viewing angle. Here, although the light converging effect is weakened, the side surface SS still has a light-collecting effect, ensuring improved brightness.

[0078] The degree of curvature of the top surface TS being smaller than the degree of curvature of the side surface SS can be limited as follows.

[0079] In a cross section of one lens LENS and the filter section CF overlapping it, perpendicular to the drive back plate BP, the curvature of any point on the contour of the top surface TS is smaller than the curvature of any point on the contour of the side surface SS. This cross section may be an optical axis passing through the lens LENS, or may be a cross section perpendicular to the drive back plate BP. For example, As shown in Figures 1 and 5, in some embodiments of the present disclosure, the top surface TS is a plane parallel to the drive backplate BP and the side surface SS is a spherical surface, in which case the curvature of any point on the top surface TS is zero and the curvature of any point on the side surface SS is greater than the top surface TS.

[0080] As shown in FIGS. 7 and 8, in another embodiment of the present disclosure, both the top surface TS and the side surface SS are spherical, but the radius of the top surface TS is smaller than the radius of the side surface.

[0081] In other embodiments of the present disclosure, the top surface TS and the side surface SS of the lens LENS may have other shapes as long as the degree of curvature of the top surface TS is smaller than that of the side surface SS, and the light-collecting effect of the top surface TS is weaker than that of the side surface SS.

[0082] Next, as shown in Figures 1, 5, 7 and 8, the surface of at least a portion of the filter unit CF away from the driving backplate BP is recessed into the driving backplate BP, and the degree of curvature of the middle area MA is less than the degree of curvature of the edge area EA. For example, the surface of the first filter unit CF1 away from the driving backplate BP is recessed into the driving backplate BP, and the degree of curvature of the middle area MA is less than the degree of curvature of the edge area EA. This has a converging effect on the transmitted light beam, allowing the light to be converged before passing through the first lens LENS, which is advantageous for improving brightness. Although the curvature of the surface of the filter unit CF away from the driving backplate BP affects the optical path, the curvature of the top surface TS and the side surface SS of the lens LENS are different, and the top surface TS is relatively gentle, so the shape of the surface of the filter unit CF away from the driving backplate BP and the surface of the lens LENS can be limited, specifically, In a cross section of the lens LENS and the filter portion CF overlapping it perpendicular to the drive back plate BP, the difference in curvature between two points on the outline of the middle region MA and the outline of the top surface TS that face each other in a direction perpendicular to the drive back plate BP can be defined as the central curvature difference between the lens LENS and the filter portion CF overlapping it, and the difference in curvature between two points on the outline of the side surface SS and the outline of the edge region EA that face each other in a direction perpendicular to the drive back plate BP can be defined as the edge curvature difference between the lens LENS and the filter portion CF overlapping it. This cross section may be an optical axis passing through the lens LENS or may be a cross section perpendicular to the drive back plate BP.

[0083] The difference in central curvature between at least the first lens LENS1 and the overlapping first filter portion CF1 can be made smaller than the difference in edge curvature, i.e., the degree of curvature of the middle area MA overlapping with the top surface TS of the first lens LENS1 can be made smaller than the degree of curvature of the edge area EA overlapping with the side surface SS, so that the degree of curvature of the first filter portion CF1 matches the degree of curvature of the surface of the first lens LENS1, and the small difference in curvature between the top surface TS and the middle area MA is advantageous for improving the color gamut and brightness uniformity. At the same time, the difference in curvature between the side surface SS and the edge area EA reduces and prevents light emitted from the edge area EA perpendicular to the side surface SS from being converged, thereby ensuring the convergence effect of the side surface SS.

[0084] Furthermore, in some embodiments of the present disclosure, the top surface TS of the first lens LENS1 may be flat, and the central curvature difference between the first lens LENS1 and the first filter section CF1 overlapping it may be less than 10% of the edge curvature difference.

[0085] Furthermore, in some embodiments of the present disclosure, the edge region EA of the second filter portion CF2 does not cover the edge regions EA of the first filter portion CF1 and the third filter portion CF3, so that the surface of the second filter portion CF2 away from the drive backplate BP is flatter than that of the first filter portion CF1, and the central curvature difference between the first lens LENS1 and the first filter portion CF1 overlapping it is greater than the central curvature difference between the second lens LENS2 and the second filter portion CF2 overlapping it.

[0086] In some embodiments of the present disclosure, the width Wt of the orthogonal projection of the top surface TS onto the drive backplate BP is greater than the width of the orthogonal projection of the side surface SS onto the drive backplate BP. The side surface SS has a strong converging effect on light rays, which causes a large gradient change in brightness and is disadvantageous to brightness uniformity, but the top surface TS has a weak converging effect on light rays (if the top surface TS is flat, there is no converging effect), so the top surface TS is advantageous for improving brightness uniformity.

[0087] In some embodiments of the present disclosure, since light cannot be converged at the lens pitch Wl, the lens pitch Wl should not be too large, and the width of the orthogonal projection of the side surface SS of the lens LENS onto the driving backplate BP can be larger than the lens pitch Wl of the adjacent lens LENS described above. If it is ensured that the adjacent lenses LENS are not glued together, a small lens pitch reduces stray light transmitted between two adjacent lenses LENS, improves the light-collecting effect, and is advantageous for improving brightness.

[0088] In this specification, the width Ws of the orthogonal projection of the side surface SS onto the driving backplate BP is the distance between the inner and outer boundaries of the orthogonal projection, and the width Ws of the orthogonal projection of the top surface TS onto the driving backplate BP is the maximum width of the orthogonal projection of the top surface TS onto the driving backplate BP in a direction parallel to the driving backplate BP.

[0089] In some embodiments of the present disclosure, the orthogonal projection of the lens LENS onto the driving backplate BP is located within the orthogonal projection of the overlapping filter unit CF onto the driving backplate BP, ensuring a sufficient lens pitch Wl and maximizing the ability of the same lens LENS to receive light rays emitted from the same filter unit CF. Furthermore, the lens LENS should not be too small; if the lens LENS is too small, many light rays will not be able to pass through the lens LENS, which is detrimental to increasing brightness. After extensive testing and simulation, the inventors proposed the following:

[0090] The lens LENS may be smaller than the corresponding filter section CF, i.e., the area of ​​the orthogonal projection of the lens LENS onto the drive back plate BP may be smaller than the area of ​​the orthogonal projection of the filter section CF that overlaps with this lens LENS onto the drive back plate BP, for example, the area of ​​the orthogonal projection of the lens LENS onto the drive back plate BP may be smaller than 0.7 to 0.8 times the area of ​​the orthogonal projection of the filter section CF that overlaps with it onto the drive back plate BP.

[0091] As shown in FIG. 5, in some embodiments of the present disclosure, the lens pitch Wl between adjacent lenses LENS may be smaller than the thickness Hb of the substrate LB of the lens layer LL, which is advantageous for reducing the spacing between the lenses LENS.

[0092] 5, in some embodiments of the present disclosure, the lens pitch Wl can be made smaller than the stack width Wp of the adjacent filter units CF. Because light is not transmitted within the range of the stack width Wp, it is possible to reduce the overflow of stray light (light that does not pass through the lens LENS) and avoid color shifts due to stray light.

[0093] As shown in FIG. 5, in some embodiments of the present disclosure, the width of the orthogonal projection of the side surface SS of the first lens LENS1 onto the driving backplate BP is greater than the stack width Wp of the first filter section CF1 and its adjacent second filter section CF2.

[0094] To improve brightness while preventing the viewing angle from becoming too small, the upper surface TS of the lens LENS should not be too large or too small. If the upper surface TS of the lens LENS is too large, the light converging effect will be too weak and the brightness will not increase too much. If the upper surface TS of the lens LENS is too small, it will be difficult to effectively increase the viewing angle. In some embodiments of the present disclosure, the area of ​​the orthogonal projection of the upper surface TS onto the driving backplate BP can be one-third or more of the area of ​​the orthogonal projection of the lens LENS onto the driving backplate BP. Of course, the orthogonal projection of the upper surface TS onto the driving backplate BP cannot completely overlap with the orthogonal projection of the lens LENS onto the driving backplate BP and is necessarily smaller than the area of ​​the orthogonal projection of the lens LENS onto the driving backplate BP.

[0095] As shown in FIG. 5 , in some embodiments of the present disclosure, the thickness of the lens layer LL may be greater than the width Wt of the orthogonal projection of the upper surface TS onto the driving backplate BP. The thickness HL of the lens layer LL may be the sum of the thickness of the lens LENS and the thickness Hb of the substrate LB. The thickness HL of the lens LENS may be the maximum distance between its upper surface TS and the color film layer CFL in a direction perpendicular to the driving backplate BP. At the same time, the thickness HL of the lens LENS may be greater than the width of the orthogonal projection of the upper surface TS onto the driving backplate BP. This allows the lens LENS to have a sufficient height, which increases the curvature of the side surface SS without changing the coverage area, thereby improving the light-collecting effect.

[0096] It should be noted that, if there is no contradiction, the above-described embodiments may be partly or entirely included in the same embodiment, and examples of various combinations will not be given here.

[0097] As shown in Figure 6, Figure 6 shows the light path when the top surface TS is flat, and it can be seen that the top surface TS does not collect light, but the side surface SS can collect light. In this case, the viewing angle at 50% of the brightness of the light emitted from the top surface TS is -α to α, where α can be 50°. Compared to the system in which the top surface TS and the side surface SS are located on the same spherical surface (measured in experiments, the viewing angle at 50% of the brightness of the light emitted from the top surface TS is 30°), the viewing angle when the brightness is attenuated by half is clearly increased.

[0098] As shown in Figure 9, Figure 9 shows the light path when the top surface TS is flat, and it can be seen that the top surface TS does not collect light, but the side surface SS can collect light. In this case, the viewing angle at 50% of the brightness of the light emitted from the top surface TS is -α to α. Compared to the system in which the top surface TS and the side surface SS are located on the same spherical surface (measured in the experiment, the viewing angle at 50% of the brightness of the light emitted from the top surface TS is 30°), the viewing angle when the brightness is attenuated by half is also clearly increased.
