Technical Field

[0001] Embodiments of the present application relate to the field of display technology, and in particular, to a display panel and a method for preparing the same, a display screen module, and an electronic device. Background Art

[0002] OLED display panels have many advantages, such as thinness, high contrast, high response speed, flexibility and foldability, etc. However, OLED display panels still have the problem of low light output efficiency. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a display panel and a method for manufacturing the same, a display screen module and an electronic device, which are used to solve the problem of low light output efficiency of the display panel.

[0004] In order to achieve the above purpose, the present application provides the following solutions:

[0005] On the one hand, a display panel is provided, comprising a display substrate, a lens layer, a touch function layer and a color film layer. The display substrate comprises a plurality of light-emitting parts. The lens layer is located on the light-emitting side of the display substrate, and the lens layer comprises a plurality of lenses. The touch function layer is located on the side of the lens layer away from the display substrate, the touch function layer comprises a transparent insulating layer and a plurality of mutually intersecting touch lines, the plurality of mutually intersecting touch lines form a mesh, the orthographic projection of the mesh on a reference plane overlaps with the orthographic projection of the light-emitting part on the reference plane, the transparent insulating layer contacts the surface of the plurality of lenses away from the display substrate, the refractive index of the transparent insulating layer is different from the refractive index of the plurality of lenses, and the reference plane is parallel to the surface of the transparent insulating layer away from the display substrate. The color film layer is located on the side of the touch function layer away from the lens layer, the color film layer includes a shading portion and a plurality of color film portions, the orthographic projection of the shading portion on the reference plane overlaps with the orthographic projection of the touch line on the reference plane, the shading portion has a plurality of openings, the plurality of color film portions are arranged in the plurality of openings, and the orthographic projection of the plurality of color film portions on the reference plane overlaps with the orthographic projection of the plurality of light-emitting portions on the reference plane.

[0006] The display panel provided in the embodiment of the present application has multiple lenses in the lens layer located below the color film layer (i.e., the light incident side of the color film layer). Therefore, the outgoing light of the light-emitting part can be first gathered and then filtered through the color film layer. Compared with the solution of arranging the multiple lenses in the lens layer above the color film layer (i.e., the light emitting side of the color film layer) and first filtering and then gathering the light, the light output efficiency can be effectively improved and a light output effect at a larger angle can be achieved. In addition, since the multiple lenses in the lens layer are placed below the touch function layer (i.e., the light incident side of the touch function layer), the touch function layer is arranged between the color film layer and the lens layer, so that the transparent insulating layer in the touch function layer can contact the surface of the multiple lenses away from the display substrate. At the same time, since the refractive index of the transparent insulating layer is different from the refractive index of the multiple lenses, the transparent insulating layer can be used to form a flat surface on the side of the transparent insulating layer away from the display substrate, and the transparent insulating layer can be reused to form a high and low refractive interface between the transparent insulating layer and the lens, which has a gathering effect on the outgoing light of the light-emitting part. With this arrangement, there is no need to add refractive film layers on both sides of the lens layer, so that the structure of the display panel is simpler and thinner, which is also conducive to simplifying the preparation process of the display panel.

[0007] In some embodiments, at least one of the lenses is a first lens, and the orthographic projection of the first lens on the reference plane overlaps with the orthographic projection of the light-emitting portion on the reference plane. With such an arrangement, the first lens can be used to gather most of the light under the positive viewing angle of the light-emitting portion, thereby achieving a good focusing effect, thereby improving the light extraction efficiency. Exemplarily, the first lens can be a convex lens, for example, the surface of the first lens close to the light-emitting portion can be a plane, and the surface of the first lens away from the light-emitting portion can be a convex surface.

[0008] In some embodiments, the distance that the orthographic projection edge of the first lens on the reference plane exceeds the orthographic projection edge of the light-emitting portion on the reference plane is in the range of 1μm-4μm, and the reference plane is parallel to the light-emitting portion. In this example, by setting the distance that the orthographic projection edge of the first lens on the reference plane exceeds the orthographic projection edge of the light-emitting portion on the reference plane to be in the range of 1μm-4μm, the large-angle light emitted by the light-emitting portion can be effectively gathered, thereby improving the light extraction efficiency.

[0009] In some embodiments, the thickness of the first lens is in the range of 1 μm to 3 μm. This configuration is conducive to ensuring that the first lens has a good light-gathering effect.

[0010] In some embodiments, the first lens includes a first side surface; along the light emitting direction of the light emitting portion, the first side surface gradually tilts toward the central axis of the first lens; the acute angle between the tangent plane of the first side surface and the reference plane is in the range of 40°-80°, and the reference plane is parallel to the light emitting portion. In this example, the first side surface can be an inclined plane or an inclined curved surface. By setting the acute angle between the tangent plane of the first side surface and the reference plane in the range of 40°-80°, the reflection angle of the light directed to the first side surface can be effectively adjusted, thereby achieving a good gathering effect on the large-angle light at the edge.

[0011] In some embodiments, the refractive index of the transparent insulating layer is lower than the refractive index of the first lens. For example, the refractive index of the transparent insulating layer may be 1.45-1.55. In this example, since the refractive index of the transparent insulating layer is lower than the refractive index of the first lens, the light emitted from the first lens to the transparent insulating layer will not be totally reflected, which is conducive to further improving the light extraction efficiency.

[0012] In some embodiments, at least one of the lenses is a second lens, and the orthographic projection of the second lens on the reference plane surrounds the orthographic projection of the light-emitting portion on the reference plane; the reference plane is parallel to the light-emitting portion. With such an arrangement, the second lens can be used to gather the large-angle light from the light-emitting portion, achieving a good light-collecting effect, thereby preventing the large-angle light from being directed to the light-shielding portion, and improving the light extraction efficiency.

[0013] In some embodiments, the second lens includes an inner circumferential surface, and the distance between the orthographic projection of the inner circumferential surface on the reference surface and the orthographic projection of the light-emitting portion on the reference surface is in the range of 0μm-4μm. In this example, by setting the distance between the orthographic projection of the inner circumferential surface on the reference surface and the orthographic projection of the light-emitting portion on the reference surface to be in the range of 0μm-4μm, the large-angle light emitted by the light-emitting portion can be effectively gathered, thereby improving the light extraction efficiency.

[0014] In some embodiments, the thickness of the second lens is in the range of 1 μm to 4 μm. This configuration is conducive to ensuring that the second lens has a good light-gathering effect.

[0015] In some embodiments, along the light emitting direction of the light emitting portion, the inner peripheral surface gradually moves away from the central axis of the lens; the acute angle between the tangent plane of the inner peripheral surface and the reference plane is in the range of 30°-90°. In this example, the inner peripheral surface can be an inclined plane or an inclined curved surface. By setting the acute angle between the tangent plane of the inner peripheral surface and the reference plane in the range of 30°-90°, the reflection angle of the light directed to the inner peripheral surface can be effectively adjusted, thereby achieving a good convergence effect on the large-angle light at the edge.

[0016] In some embodiments, the refractive index of the transparent insulating layer is higher than the refractive index of the second lens. For example, the refractive index of the transparent insulating layer may be 1.6-1.8. In this example, since the refractive index of the transparent insulating layer is higher than the refractive index of the second lens, it is not easy for the light in the second lens to pass through the transparent insulating layer to the light shielding portion, which is beneficial to increase the light output of the area facing the light emitting portion, thereby improving the display brightness.

[0017] In some embodiments, the light shielding portion contacts the touch wiring. In this way, the light shielding portion in the color filter layer can be used to directly cover the top touch wiring, so that the insulating layer in the touch function layer for covering the top touch wiring can be omitted. The top layer refers to the layer farthest from the display substrate. This can simplify the structure of the display panel and the manufacturing process of the display panel.

[0018] In some embodiments, the touch function layer includes a first wiring layer and a second wiring layer; the multiple intersecting touch lines are located in the first wiring layer and the second wiring layer; the transparent insulating layer includes a first insulating layer and a second insulating layer, the first insulating layer is located on the side of the lens layer away from the display substrate; the first wiring layer is located on the side of the first insulating layer away from the lens layer; the second insulating layer is located on the side of the first wiring layer away from the first insulating layer; the second wiring layer is located on the side of the second insulating layer away from the first wiring layer; the second wiring layer is in contact with the shading portion, and the first insulating layer is in contact with the second insulating layer. With such a configuration, on the one hand, the touch function layer can realize the touch control function, and on the other hand, the shading portion in the color filter layer can be used to directly cover the touch lines of the top layer, so that the transparent insulating layer only includes the first insulating layer and the second insulating layer, and there is no need to set a third insulating layer above the second wiring layer.

[0019] In some embodiments, the refractive index of the lens layer is in the range of 1.6-1.8. With such an arrangement, the multiple lenses in the lens layer are high-refractive lenses, which is beneficial to improving light extraction efficiency.

[0020] In some embodiments, the display substrate includes an encapsulation layer, the encapsulation layer includes a first inorganic layer, an organic layer, and a second inorganic layer that are sequentially away from the light-emitting portion, and the refractive index of the second inorganic layer is greater than the refractive index of the lens. In this embodiment, since the refractive index of the second inorganic layer is greater than the refractive index of the lens, the light emitted from the second inorganic layer to the lens will not be totally reflected, which is conducive to further improving the light extraction efficiency.

[0021] In some embodiments, the lens is used to gather the light emitted from the light emitting unit. In this embodiment, the light emitted from the light emitting unit can be gathered well by adjusting the refractive index relationship between the lens and the transparent insulating layer, the refractive index relationship between the lens and the second inorganic layer, and the shape of the lens itself.

[0022] In some embodiments, a light-emitting portion corresponds to a lens, an opening, a color film portion, and a mesh, wherein the orthographic projection of the light-emitting portion on the reference surface and the orthographic projection of the corresponding opening on the reference surface, the orthographic projection of the corresponding color film portion on the reference surface, and the orthographic projection of the corresponding mesh on the reference surface have a common overlapping area. In this embodiment, the light emitted by a light-emitting portion can be modulated (such as gathered) by a lens, and then emitted to the color film portion at an opening through a mesh, so that the light between different light-emitting portions is not prone to crosstalk, thereby improving the display contrast. In addition, through a one-to-one regulation method, it is also helpful to prevent more light from being blocked by the shading portion, further improve the light output efficiency, and achieve a larger angle light output effect.

[0023] On the other hand, a method for preparing a display panel is provided, comprising: forming a display substrate, the display substrate comprising a plurality of light-emitting portions; forming a lens layer, the lens layer being located on a light-emitting side of the display substrate, the lens layer comprising a plurality of lenses; forming a touch function layer, the touch function layer being located on a side of the lens layer away from the display substrate, the touch function layer comprising a transparent insulating layer and a plurality of mutually intersecting touch traces, the plurality of mutually intersecting touch traces forming a mesh, the orthographic projection of the mesh on a reference plane overlapping the orthographic projection of the light-emitting portion on the reference plane; the transparent insulating layer and the plurality of lenses being away from the display substrate The touch function layer is in contact with the surface of the display substrate, the refractive index of the transparent insulating layer is different from the refractive index of the multiple lenses; the reference plane is parallel to the surface of the transparent insulating layer away from the display substrate; a color film layer is formed, and the color film layer is located on the side of the touch function layer away from the lens layer; the color film layer includes a shading portion and a plurality of color film portions, the orthographic projection of the shading portion on the reference plane overlaps with the orthographic projection of the touch wiring on the reference plane, the shading portion has a plurality of openings, the plurality of color film portions are arranged in the plurality of openings, and the orthographic projection of the plurality of color film portions on the reference plane overlaps with the orthographic projection of the plurality of light-emitting portions on the reference plane.

[0024] The method for preparing a display panel provided in the embodiment of the present application can form a display panel. In the display panel, since the multiple lenses in the lens layer are located below the color filter layer (i.e., the light incident side of the color filter layer), the light emitted by the light-emitting part can be gathered first and then filtered through the color filter layer. Compared with the solution of setting the multiple lenses in the lens layer above the color filter layer (i.e., the light exiting side of the color filter layer), filtering first and then gathering the light, the light extraction efficiency can be effectively improved, and a larger angle light extraction effect can be achieved. In addition, since the multiple lenses in the lens layer are placed below the touch function layer (i.e., the light incident side of the touch function layer), the touch function layer is arranged between the color film layer and the lens layer, so that the transparent insulating layer in the touch function layer can contact the surface of the multiple lenses away from the display substrate. At the same time, since the refractive index of the transparent insulating layer is different from the refractive index of the multiple lenses, the transparent insulating layer can be used to form a flat surface on the side of the transparent insulating layer away from the display substrate, and the transparent insulating layer can be reused to form a high and low refractive interface between the transparent insulating layer and the lens, which has a gathering effect on the outgoing light of the light-emitting part. With this arrangement, there is no need to add refractive film layers on both sides of the lens layer, so that the structure of the display panel is simpler and thinner, which is also conducive to simplifying the preparation process of the display panel.

[0025] On the other hand, a display screen module is provided. It includes: the display panel in any of the previous embodiments; and a flexible circuit board, one end of which is electrically connected to the display panel. In this embodiment, the display panel is combined with the flexible circuit board, and the display panel is conveniently electrically connected to other devices by providing the flexible circuit board. In addition, the display screen module provided in the embodiment of the present application includes the display panel in any of the previous embodiments, and thus has the beneficial effects of the display panel in any of the previous embodiments, which will not be described in detail here.

[0026] On the other hand, an electronic device is provided, comprising: a control circuit board; and a front display screen module, wherein the second end of the flexible circuit board in the display screen module is electrically connected to the control circuit board. This arrangement enables the control circuit board to control the display panel. In addition, the electronic device provided in the embodiment of the present application, since it includes the display panel in any of the aforementioned embodiments, has the beneficial effects of the display panel in any of the aforementioned embodiments, which will not be repeated here.

[0047] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present application. For ease of description, the width direction of the electronic device 1000 is defined as the X1 axis; the length direction of the electronic device 1000 is defined as the Y1 axis; and the thickness direction of the electronic device 1000 is defined as the Z1 axis. It is understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.

[0048] exist Figure 1 In the embodiment of the present invention, the electronic device 1000 is a mobile phone. Exemplarily, the electronic device 1000 may include a display panel 1. In addition, the electronic device 1000 may also include a back cover 1001, a circuit board (not shown), a battery (not shown) and other components. It is understood that Figure 1 Only some components of the electronic device 1000 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 As well as the limitations of the following figures. For example, in some other examples, the electronic device 1000 may not include a battery, for example, it may be directly connected to an external power source for use.

[0049] Exemplarily, the display panel 1 can be combined with a flexible circuit board to form a display screen module. In some examples, a first end of the flexible circuit board is bound and connected to a side edge of the display panel 1, and a connector is provided at the other end of the flexible circuit board, and the connector is used to be plugged with a control circuit board in the electronic device 1000. Such a configuration makes the display module easier to install and disassemble.

[0050] The display panel 1 is used to display images, videos, etc. The display panel 1 can be a flexible display screen or a rigid display screen; illustratively, the display panel 1 can be any one of an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a quantum dot light-emitting diode (QLED) display screen, and a liquid crystal display (LCD).

[0051] The back shell 1001 is used to protect the internal electronic components (such as circuit boards, batteries) of the electronic device 1000. Among them, the back shell 1001 may include a back cover and a middle frame, and the middle frame is fixed to the back cover. Exemplarily, the middle frame can be fixedly connected to the back cover by adhesive. The middle frame can also be an integrally molded structure with the back cover, that is, the middle frame and the back cover are an integral structure. The display panel 1 can be connected to the middle frame. The aforementioned circuit board, battery and other components may be provided in the space between the screen, the middle frame and the back cover. The circuit board may include a flexible circuit board and a rigid circuit board. Power devices such as chips may be provided on the circuit board.

[0052] Based on the above electronic device 1000, the inventor of the present application has found that it has a problem of low light extraction efficiency. Taking the electronic device 1000 including an OLED display panel as an example, the OLED display panel has many advantages, such as light, thin, high contrast, high response speed, flexible and foldable. With the development and upgrading of high dynamic range imaging (English: High Dynamic Range Imaging, referred to as HDRI or HDR) technology and the demand for outdoor use scenarios, consumers have higher and higher demands for the brightness of display products. The current OLED display panel is limited by factors such as the luminous efficiency of the material of the electroluminescence (EL) layer, the external quantum efficiency (EQE) of the OLED display panel, and the opening size of the pixel definition layer (PDL), and the brightness still has a lot of room for improvement. Among them, due to the surface plasmon polaritons (SPP) loss of the cathode and anode interfaces on both sides of the EL layer, the waveguide loss inside the OLED display panel, and the absorption of the material, the EQE of the OLED display panel is less than 20%.

[0053] See also Figures 2 to 4 , Figure 2 This is a structural diagram of a display panel (without the low-folding lens 112) provided in an embodiment of the present application. Figure 3 This is a structural diagram of another display panel (provided with a low-folding lens 112) provided in an embodiment of the present application. Figure 4 for Figure 2 and Figure 3 Brightness curves of the display panel at different viewing angles in the embodiment.

[0054] In some embodiments, Figure 2 As shown, the display panel 1 is an OLED display panel, and the OLED display panel includes a display substrate 100, a touch function layer 200, a high-refractive transparent flat layer 113 and a glass cover 114. In other embodiments, such as Figure 3 As shown, compared to Figure 2 For the display panel 1 shown in the figure, a low-folding lens 112 is added between the touch function layer 200 and the high-folding transparent flat layer 113. Figure 4 It can be seen that the low-refractive lens 112 is combined with the high-refractive transparent flat layer 113 to improve the brightness of light within a small angle range (such as within 20 degrees). Figure 2 and Figure 3 It can be seen that Figure 3 The display panel shown mainly transfers light exceeding 30° to the normal viewing angle direction to achieve the effect of improving power consumption, but it also causes an increase in light attenuation at 30°.

[0055] The display substrate 100 may include a substrate 101, a circuit structure layer 102 (for example, including a pixel circuit and a gate driving circuit, etc.), an anode 103, a pixel definition layer 105, a light-emitting portion 104, a cathode 106, and an encapsulation layer 110, which are stacked in sequence. The encapsulation layer 110 may include, for example, a first inorganic layer 107, an organic layer 108, and a second inorganic layer 109.

[0056] Figure 5 This is a structural diagram of another display panel provided in an embodiment of the present application. Figure 5 , the display panel 1 is also an OLED display panel. Figure 3 The difference of the embodiment is that the circuit structure layer 102 and the anode 103 are not shown, and the light extraction layer C1 and the anti-reflection layer C2 are added between the cathode 106 and the encapsulation layer 110. Exemplarily, the material of the light extraction layer C1 includes organic matter, and the light extraction layer C1 can suppress the SPP effect to adjust the light extraction efficiency. Exemplarily, the anti-reflection layer C2 can be a lithium fluoride layer, and the anti-reflection layer C2 can make the light reflect multiple times therein, and after interference superposition, it is emitted to the encapsulation layer 110, thereby improving the light extraction efficiency.

[0057] also, Figure 5The display panel in the embodiment does not have a touch function layer 200, but directly has a color filter layer 300 outside the encapsulation layer 110, the color filter layer 300 includes a light shielding portion 301 and multiple color filter portions 302, the light shielding portion 301 has multiple openings, and the multiple color filter portions 302 are arranged in the multiple openings. Exemplarily, the multiple light-emitting portions may include a red light-emitting portion, a green light-emitting portion, and a blue light-emitting portion, and the multiple color filter portions 302 may include a red color filter portion 302, a green color filter portion 302, and a blue color filter portion 302. The red color filter portion 302 may be located on the light-emitting side of the red light-emitting portion, the green color filter portion 302 may be located on the light-emitting side of the green color filter portion 302, and the blue color filter portion 302 may be located on the light-emitting side of the blue light-emitting portion. By providing the color filter layer 300, a (Color filter On Encapsulation, COE) structure may be formed, which plays a role in reducing the reflection of external ambient light, thereby eliminating the polarizer, and therefore, it may also be called a polarizer-free technology.

[0058] Exemplarily, a surface treatment layer 115 may be formed on the light emitting surface of the glass cover plate 114 , and the surface treatment layer 115 may, for example, improve the surface hardness.

[0059] Figure 6 Provided in the embodiments of this application Figure 5 The brightness curve of the three colors of light in the display panel. Figure 5 and Figure 6 It can be seen that the COE structure itself will also lead to an increase in light attenuation, because the existence of the light shielding portion 301 in the OLED display panel will block a portion of the light with a large viewing angle.

[0060] Figure 7 A structural diagram of another display panel provided in an embodiment of the present application. Figure 7 In some embodiments of the present application, the display panel 1 includes a display substrate 100 , a touch function layer 200 , a color film layer 300 , two high-refractive transparent flat layers 113 and a low-refractive lens 112 .

[0061] Compared to Figure 3 The difference between the embodiment of the embodiment of the present invention is that the display substrate 100 does not show the substrate 101, the circuit structure layer 102, the anode 103 and the cathode 106, but adds a flat layer PLN (i.e., a flat layer located between the circuit structure layer 102 and the anode 103) and a color filter layer 300, and does not show the glass cover 114. In addition, the low-refractive lens 112 is arranged on the light-emitting side of the color filter layer 300, and the high-refractive transparent flat layer 113 is filled on both sides of the lens layer 400. Figure 7As for the display panel 1 shown, there are at least two problems: first, two high-refractive transparent flat layers 113 and low-refractive lenses 112 are provided on the light-emitting side of the color filter layer 300, which makes the process more complicated; second, the color filter layer 300 itself will attenuate the light at a large angle (based on the above Figure 5 and Figure 6 As can be seen, placing the low-refractive lens 112 on the light-emitting side of the color filter layer 300 will further attenuate the large-angle light.

[0062] Based on the above problems, the present application embodiment provides another display panel 1, see Figure 8 , Figure 8 This is a structural diagram of another display panel 1 provided in an embodiment of the present application. The display panel 1 includes a display substrate 100 , a lens layer 400 , a touch function layer 200 and a color filter layer 300 .

[0063] The structure of the display substrate 100 can refer to the description in the previous text. The display substrate 100 includes a plurality of light-emitting units 104. The lens layer 400 is located on the light-emitting side of the display substrate 100, and the lens layer 400 includes a plurality of lenses 40A. The lens 40A can gather the emitted light of the light-emitting unit 104. In some examples, one lens 40A may be set corresponding to one light-emitting unit 104. In other examples, multiple lenses 40A may be set corresponding to one light-emitting unit 104.

[0064] The touch function layer 200 is located on the side of the lens layer 400 away from the display substrate 100. The touch function layer 200 includes a transparent insulating layer 20C and a plurality of intersecting touch lines 20A. The plurality of intersecting touch lines 20A form a mesh 20B. The orthographic projection of the mesh 20B on the reference plane M overlaps with the orthographic projection of the light-emitting portion 104 on the reference plane M. The reference plane M can be parallel to the surface of the transparent insulating layer 20C away from the display substrate 100. Here, the orthographic projection of the mesh 20B on the reference plane M overlaps with the orthographic projection of the light-emitting portion 104 on the reference plane M, including partial overlap and full overlap. When partially overlapping, the light-emitting portion 104 is not completely covered by the mesh 20B, and the light of the light-emitting portion 104 can partially or completely pass through the mesh 20B. When all overlap, the orthographic projection of the light-emitting portion 104 on the reference plane M may be located within the orthographic projection range of the edge of the mesh 20B (such as the touch trace 20A) on the reference plane M. Such a configuration is conducive to allowing more emitted light from the light-emitting portion 104 to pass through the mesh 20B, thereby improving the display brightness. In other embodiments, the orthographic projection of the mesh 20B on the reference plane M and the orthographic projection of the light-emitting portion 104 on the reference plane M may not overlap. In this case, since there is a certain distance between the mesh 20B and the light-emitting portion, the mesh 20B can still allow the emitted light of the light-emitting portion 104 to pass through.

[0065] The color filter layer 300 is located on the side of the touch function layer 200 away from the lens layer 400. The color filter layer 300 includes a light shielding portion 301 and a plurality of color filter portions 302. The light shielding portion 301 has a plurality of openings 30A, and the plurality of color filter portions 302 are disposed in the plurality of openings 30A.

[0066] The orthographic projection of the light shielding portion 301 on the reference plane M overlaps with the orthographic projection of the touch line 20A on the reference plane M. Here, it also includes partial overlap and full overlap. By setting the orthographic projection of the light shielding portion 301 on the reference plane M to overlap with the orthographic projection of the touch line 20A on the reference plane M, it is possible to avoid affecting the display effect due to the reflection of external light by the touch line 20A. In other embodiments, the orthographic projection of the light shielding portion 301 on the reference plane M and the orthographic projection of the touch line 20A on the reference plane M may not overlap. In this case, the alignment accuracy can be reduced, thereby reducing the difficulty of manufacturing the display panel 1.

[0067] The orthographic projections of the multiple color filter parts 302 on the reference plane M overlap with the orthographic projections of the multiple light-emitting parts 104 on the reference plane M. Here, the orthographic projections of the multiple color filter parts 302 on the reference plane M overlap with the orthographic projections of the multiple light-emitting parts 104 on the reference plane M. The color filter parts 302 can be used to filter the outgoing light of the light-emitting parts 104. Exemplarily, one color filter part 302 can be set corresponding to one light-emitting part 104. In other embodiments, the orthographic projections of the multiple color filter parts 302 on the reference plane M and the orthographic projections of the multiple light-emitting parts 104 on the reference plane M may not overlap. In this case, it is only necessary to ensure that the outgoing light of the light-emitting part 104 can be directly or indirectly projected to the corresponding color filter part 302 through other light-guiding structures, and the color filter part 302 can be used to filter the outgoing light of the light-emitting part 104.

[0068] The display panel 1 provided in the above-mentioned embodiment of the present application, since the multiple lenses 40A in the lens layer 400 are located below the color filter layer (in the direction shown in the figure, i.e., the light incident side of the color filter layer 300), the outgoing light of the light-emitting portion 104 can be first gathered and then filtered through the color filter layer 300. Compared with the solution of arranging the multiple lenses 40A in the lens layer 400 above the color filter layer (i.e., the light emitting side of the color filter layer), first filtering and then gathering the light, the light output efficiency can be effectively improved, and a light output effect at a larger angle can be achieved. In addition, since the multiple lenses 40A in the lens layer 400 are placed below the touch function layer 200 (in the direction shown in the figure, that is, the light incident side of the touch function layer 200), the touch function layer 200 is arranged between the color film layer 300 and the lens layer 400, so that the transparent insulating layer 20C of the touch function layer 200 can be in contact with the surface of the multiple lenses 40A away from the display substrate 100, and since the refractive index of the transparent insulating layer 20C is different from the refractive index of the multiple lenses 40A, the transparent insulating layer 20C can be used to form a flat surface on the side of the transparent insulating layer 20C away from the display substrate 100, and the transparent insulating layer 20C can be reused to form a high-low refractive interface between the transparent insulating layer 20C and the lens 40A, which has a gathering effect on the outgoing light of the light-emitting portion 104, that is, compared with Figure 7 For the embodiment, two high-refractive transparent flat layers 113 can be reduced, thereby reducing two MASK processes. Therefore, the display panel 1 provided in the embodiment of the present application also has the advantages of simple structure, lighter and thinner, and easier to manufacture.

[0069] Exemplarily, a light-emitting portion 104 may correspond to a lens 40A, an opening 30A, a color film portion 302, and a mesh 20B, wherein the orthographic projection of the light-emitting portion 104 on the reference plane M and the orthographic projection of the corresponding opening 30A on the reference plane M, the orthographic projection of the corresponding color film portion 302 on the reference plane M, and the orthographic projection of the corresponding mesh 20B on the reference plane M, have a common overlapping area. In this embodiment, the light emitted by a light-emitting portion 104 can be modulated (such as gathered) by a lens 40A, and then projected to the color film portion 302 at an opening 30A through a mesh 20B, so that the light between different light-emitting portions 104 is not prone to crosstalk, thereby improving the display contrast. In addition, through a one-to-one regulation method, it is also helpful to prevent more light from being blocked by the shading portion 301, further improve the light output efficiency, and achieve a light output effect at a larger angle.

[0070] In some examples, such as Figure 7 As shown, the transparent insulating layer 20C includes a first insulating layer 203, a second insulating layer 204 and a third insulating layer 205 that are in contact with each other. Figure 8As shown, the transparent insulating layer 20C only includes the first insulating layer 203 and the second insulating layer 204 in contact with each other, but does not include the third insulating layer 205. In the above two examples, the transparent insulating layer 20C can be used to replace the two high-refractive transparent flat layers 113, thereby reducing at least two MASK processes. Among them, the first insulating layer 203, the second insulating layer 204 and the third insulating layer 205 can be organic insulating layers.

[0071] For example, the light shielding portion 301 contacts the touch wiring 20A. In this way, the light shielding portion 301 in the color filter layer 300 can be used to directly cover the top touch wiring 20A, so that the insulating layer (such as the third insulating layer 205) located in the touch function layer 200 for covering the top touch wiring 20A can be omitted. The top layer refers to the layer farthest from the display substrate 100. Therefore, compared with Figure 7 For the embodiment, the third insulating layer 205 is reduced, that is, one more MASK process is reduced, that is, the structure of the display panel 1 is further simplified, and the manufacturing process of the display panel 1 is simplified.

[0072] In some examples, the touch function layer 200 may further include a first wiring layer 201 and a second wiring layer 202, and the plurality of mutually intersecting touch lines 20A are located in the first wiring layer 201 and the second wiring layer 202. Figure 8 , the first insulating layer 203 is located on the side of the lens layer 400 away from the display substrate 100, the first wiring layer 201 is located on the side of the first insulating layer 203 away from the lens layer 400, the second insulating layer 204 is located on the side of the first wiring layer 201 away from the first insulating layer 203, and the second wiring layer 202 is located on the side of the second insulating layer 204 away from the first wiring layer 201. Exemplarily, the touch wiring 20A in the second wiring layer 202 can directly contact the light shielding portion 301 in the color filter layer 300, that is, compared with Figure 7 For the embodiment of the present invention, the third insulating layer 205 is reduced. The touch function layer 200 is used to realize the touch control function.

[0073] Next, the lens 40A in the embodiment of the present application is introduced.

[0074] In some embodiments, Figure 8 As shown, at least one lens 40A in the lens layer 400 is a first lens 401. The orthographic projection of the first lens 401 on the reference plane M overlaps with the orthographic projection of the light-emitting portion 104 on the reference plane M. Here, the orthographic projection also includes partial overlap and full overlap. With such a configuration, the first lens 401 can be used to gather most of the light at the normal viewing angle of the light-emitting portion 104, achieving a good focusing effect, thereby improving the light extraction efficiency.

[0075] Exemplarily, the distance a1 by which the orthographic projection edge of the first lens 401 on the reference plane M exceeds the orthographic projection edge of the light-emitting portion 104 on the reference plane M is in the range of 1 μm-4 μm. For example, the distance a1 by which the orthographic projection edge of the first lens 401 on the reference plane M exceeds the orthographic projection edge of the light-emitting portion 104 on the reference plane M may be 1 μm, 2 μm, 3.5 μm or 4 μm, etc. The reference plane M is parallel to the light-emitting portion.

[0076] In this example, by setting the distance a1 of the orthographic projection edge of the first lens 401 on the reference plane M beyond the orthographic projection edge of the light-emitting portion 104 on the reference plane M to a value range of 1μm-4μm, the large-angle light emitted by the light-emitting portion 104 can be effectively gathered, thereby improving the light output efficiency.

[0077] For example, the thickness a2 of the first lens 401 is in the range of 1 μm to 3 μm. This configuration is conducive to ensuring that the first lens 401 has a good light-collecting effect.

[0078] Exemplarily, the first lens 401 includes a first side surface P1. Along the light emitting direction of the light emitting portion 104, the first side surface P1 gradually approaches the central axis of the first lens 401; the acute angle m1 between the tangent surface of the first side surface P1 and the reference surface M has a value range of 40°-80°, for example, the acute angle m1 between the tangent surface of the first side surface P1 and the reference surface M can be 40°, 50°, 60°, 70° or 80°, etc., wherein the reference surface M is parallel to the light emitting portion 104.

[0079] In this example, the first side surface P1 can be an inclined plane or an inclined curved surface. By setting the value range of the acute angle m1 between the tangent plane of the first side surface P1 and the reference plane M to 40°-80°, the reflection angle of the light directed to the first side surface P1 can be effectively adjusted, thereby achieving a good gathering effect on the large-angle light at the edge.

[0080] For example, in Figure 8 In the embodiment of the present invention, the refractive index of the transparent insulating layer 20C is lower than the refractive index of the first lens 401. For example, the refractive index of the transparent insulating layer 20C may be 1.45 to 1.55. In this example, since the refractive index of the transparent insulating layer 20C is lower than the refractive index of the first lens 401, the light emitted from the first lens 401 to the transparent insulating layer 20C will not be totally reflected, which is conducive to further improving the light extraction efficiency.

[0081] Fig. 9 A structural diagram of another display panel provided in an embodiment of the present application.

[0082] In some embodiments, Fig. 9As shown, at least one lens 40A in the lens layer 400 is a second lens 402, and the orthographic projection of the second lens 402 on the reference plane M surrounds the orthographic projection of the light-emitting portion 104 on the reference plane M (at this time, the orthographic projection of the second lens 402 on the reference plane M and the orthographic projection of the light-emitting portion 104 on the reference plane M may not overlap). The reference plane M is parallel to the light-emitting portion 104. With such an arrangement, the second lens 402 can be used to gather the large-angle light of the light-emitting portion 104, achieving a good light-collecting effect, thereby preventing the large-angle light from being directed to the light-shielding portion 301, and improving the light extraction efficiency.

[0083] Exemplarily, the second lens 402 includes an inner circumferential surface P2, and the distance b1 between the orthographic projection of the inner circumferential surface P2 on the reference surface M and the orthographic projection of the light-emitting portion 104 on the reference surface M has a value range of 0μm-4μm. For example, the distance b1 between the orthographic projection of the inner circumferential surface P2 on the reference surface M and the orthographic projection of the light-emitting portion 104 on the reference surface M has a value range of 2μm-3μm; for another example, the distance b1 between the orthographic projection of the inner circumferential surface P2 on the reference surface M and the orthographic projection of the light-emitting portion 104 on the reference surface M can be 0μm, 1μm, 2μm, 3μm or 4μm, etc. In this example, by setting the distance b1 between the orthographic projection of the inner circumferential surface P2 on the reference surface M and the orthographic projection of the light-emitting portion 104 on the reference surface M to have a value range of 0μm-4μm, the large-angle light emitted by the light-emitting portion 104 can be effectively gathered, thereby improving the light extraction efficiency.

[0084] For example, the thickness b2 of the second lens 402 is in the range of 1 μm to 4 μm. This configuration is conducive to ensuring that the second lens 402 has a good light-collecting effect.

[0085] Exemplarily, along the light emitting direction of the light emitting portion 104, the inner circumferential surface P2 gradually moves away from the central axis of the second lens 402; the acute angle m2 between the tangent plane of the inner circumferential surface P2 and the reference plane M has a value range of 30°-90°. For example, the acute angle m2 between the tangent plane of the inner circumferential surface P2 and the reference plane M can be 30°, 40°, 50°, 60°, 70°, 80° or 90°, etc., wherein the reference plane M is parallel to the light emitting portion 104.

[0086] In this example, the inner surface P2 can be an inclined plane or an inclined curved surface. The value range of the acute angle m2 between the tangent plane of the inner surface P2 and the reference surface M is 30°-90°, which can effectively adjust the reflection angle of the light directed to the inner surface P2, thereby achieving a good convergence effect on the large-angle light at the edge.

[0087] For example, in Fig. 9In the embodiment of the present invention, the refractive index of the transparent insulating layer 20C is higher than the refractive index of the second lens 402. For example, the refractive index of the transparent insulating layer 20C may be 1.6-1.8. In this example, since the refractive index of the transparent insulating layer 20C is higher than the refractive index of the second lens 402, it is not easy for the light in the second lens 402 to be emitted to the light shielding portion 301 through the transparent insulating layer 20C, which is beneficial to increase the light output of the area directly facing the light emitting portion 104, thereby improving the display brightness.

[0088] For example, in Fig. 9 In the embodiment of the present invention, the refractive index of the transparent insulating layer 20C can be equal to or substantially equal to the refractive index of the second inorganic layer 109, for example, the difference between the refractive indices of the two can be less than 0.1. Such a configuration is conducive to further increasing the light output of the area facing the light-emitting portion 104, thereby increasing the display brightness.

[0089] For example, the thickness of the transparent insulating layer 20C may be 2 um-5 um. In this way, the lens layer 400 can be effectively covered to form a flat surface.

[0090] In some embodiments, the refractive index of the lens layer 400 is in the range of 1.6-1.8. With such configuration, the multiple lenses 40A in the lens layer 400 are high-refractive lenses, which is beneficial to improving light extraction efficiency.

[0091] In some embodiments, continue to refer to Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 The display substrate 100 includes an encapsulation layer 110, which includes a first inorganic layer 107, an organic layer 108 and a second inorganic layer 109 which are sequentially away from the light-emitting portion 104, and the refractive index of the second inorganic layer 109 is greater than the refractive index of the lens 40A.

[0092] In this embodiment, since the refractive index of the second inorganic layer 109 is greater than the refractive index of the lens 40A, the light emitted from the second inorganic layer 109 to the lens 40A will not be totally reflected, which is beneficial to further improve the light extraction efficiency.

Fig.13 It is a data graph of reflectivity index and power consumption benefit under different lens layer thicknesses. Table 1 is a comparison table of the first simulation device (A), the second simulation device (B) and the third simulation device (C).

[0096] in, Fig.10 In the embodiment shown, there is only one low folding layer, which is equivalent to a common display panel 1 with a COE structure; Fig.11 In the embodiment shown, a high-fold layer is further introduced, and the low-fold layer forms a ring-shaped low-fold lens, which is equivalent to the previous Figure 7 The structure in Fig.12 In the embodiment shown, a high-fold lens plus a low-fold layer is used, which is equivalent to the previous Figure 8 The structure in. SCI (Specular Component Include) refers to the expression method of measuring color including specular reflected light. Further, it can be seen from Table 1 that the SCI reflectivity of the third simulation device (C) increases by 0.13% relative to the first simulation device (A); the SCI reflectivity of the second simulation device (B) increases by 0.86% relative to the first simulation device (A); that is, the reflectivity of the third simulation device (C) decreases by 0.73% relative to the second simulation device (B). Combined Fig.13 It can be seen that every 0.1% reflectivity corresponds to a 2.1% power consumption benefit. Therefore, when the reflectivity is reduced by 0.73%, the power consumption benefit will be increased by 15.33%.

[0097] From the above analysis, it can be seen that the solution including the first lens 401 provided in the embodiment of the present application has lower reflectivity and less impact on power consumption compared to the solution including the low-refractive lens 112, thereby improving the light extraction efficiency.

[0100] As can be seen from Table 2, Figure 8 The display panel in Figure 7 For the display panel in the OLED TV, at least two masks are reduced, the attenuation of 30° wide-angle light is improved, and the SCI reflectivity is reduced. In addition, there is a certain optimization effect on JNCD. JNCD is a standard for measuring the color accuracy of the screen. The smaller the JNCD value, the more accurate the color display of the screen.
