[0012] Preferably, the display panel further includes a touch layer disposed between the light-transmitting layer and the pixel definition layer.

[0013] Preferably, the display panel further includes an encapsulation layer disposed between the touch layer and the pixel definition layer.

[0014] Preferably, the light-transmitting layer has a light-focusing structure corresponding to the sub-pixel, the light-focusing structure including a refractive surface, and the light emitted from the sub-pixel is refracted and focused on the refractive surface.

[0015] Preferably, the first light-shielding layer further includes a light-shielding member disposed in the first light-transmitting opening, wherein the orthographic projection of the light-shielding member on the substrate at least partially overlaps with the orthographic projection of the separator on the substrate.

[0017] Preferably, the light-transmitting layer includes a first light-transmitting sub-layer and a second light-transmitting sub-layer stacked sequentially in the first direction. The refractive index of the first light-transmitting sub-layer is less than that of the second light-transmitting sub-layer. A through hole is formed on the first light-transmitting sub-layer, and the opening area of ​​the through hole gradually decreases along the direction from the first light-transmitting sub-layer to the substrate. The second light-transmitting sub-layer fills the through hole.

[0025] The beneficial effects of this application are as follows: Unlike existing technologies, the display panel provided in this application has a separator in the pixel opening, dividing the pixel opening where the sub-pixel is located into multiple parts, such as two or more sub-openings. The separator reduces the opening area of ​​the pixel opening, and at the same time, because the separator blocks part of the large-viewing-angle light emitted by the sub-pixel, that is, the part of the light with a small angle with the plane of the substrate is blocked and absorbed by the separator, the viewing angle of the sub-pixel's light emission is narrowed, so that the light emitted from the sub-pixel is concentrated in the direction perpendicular to the substrate. The display panel of this application has a first light-shielding layer on its surface, which further absorbs and blocks the light outside the first light-transmitting opening, narrows the light-emitting viewing angle, realizes the privacy function, and reduces the probability of the light from the display panel forming extra images on other side structures. At the same time, since the light emitted vertically from the sub-pixel is not blocked or absorbed by the separator or the first light-shielding layer, the loss of direct light can be reduced, the brightness of direct light can be guaranteed, the luminous efficiency can be guaranteed, and the impact on service life and power consumption can be reduced.

[0032] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] See Figure 1 , Figure 1This is a schematic diagram of one embodiment of the display panel of this application. The display panel 10 includes a substrate 11, a pixel definition layer 12, sub-pixels 13, separators 14, and a first light-shielding layer 18. The substrate 11 includes a substrate 111 and an array layer 112 stacked along a first direction Z. The pixel definition layer 12 is disposed on one side of the substrate 11, specifically on the side of the array layer 112 opposite to the substrate 111. A pixel opening 121 is formed on the pixel definition layer 12, and the pixel definition layer 12 can be made of a light-absorbing material. The sub-pixels 13 are disposed in the pixel opening 121. The sub-pixels 13 include a first electrode 131, a light-emitting material layer 132, and a second electrode 133 stacked sequentially along the first direction Z. The first electrode 131 can be an anode, and the second electrode 133 can be a cathode. The sub-pixels 13 include a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Specifically, the first electrode 131 in each sub-pixel 13 is a continuous film layer, and the second electrode 133 in each sub-pixel 13 is also a continuous film layer. The first electrode 131 is disposed between the pixel definition layer 12 and the array layer 112, and a portion of the first electrode 131 is exposed in the pixel opening 121. The separator 14 is disposed in the pixel opening 121, dividing the light-emitting material layer 132 in the sub-pixel 13 into multiple parts. Specifically, the separator 14 divides the pixel opening 121 into multiple sub-openings (not shown). After the light-emitting material is deposited in the sub-openings, the separator 14 divides the light-emitting material layer 132 in the sub-pixel 13 into multiple parts. Optionally, the material of the separator 14 can be a light-absorbing material, the same as the material of the pixel definition layer 12. The two can be formed simultaneously. The separator 14 and the pixel definition layer 12 are disposed in the same layer, and the thickness of the separator 14 and the pixel definition layer 12 in the first direction can be the same. The first light-shielding layer 18 is disposed on the side of the sub-pixel 13 away from the substrate 11. The first light-shielding layer 18 is provided with a first light-transmitting opening 182 corresponding to the sub-pixel 13. Specifically, the material of the first light-shielding layer 18 can be black matrix. The orthographic projection of the first light-transmitting opening 182 on the substrate 11 and the orthographic projection of the pixel opening 121 on the substrate 11 partially overlap. Preferably, the orthographic projection of the first light-transmitting opening 182 on the substrate 11 and the orthographic projection of the pixel opening 121 on the substrate 11 completely overlap.

[0034] The display panel 10 provided in this application has a separator 14 in the pixel opening 121, dividing the pixel opening 121 where the sub-pixel 13 is located into multiple parts, such as two or more sub-openings. The separator 14 reduces the opening area of ​​the pixel opening 121. At the same time, since the separator 14 blocks part of the wide-viewing-angle light emitted by the sub-pixel 13, that is, the part of the light with a small angle with the plane where the substrate 11 is located is blocked and absorbed by the separator 14, the viewing angle of the light emitted by the sub-pixel 13 is narrowed, so that the light emitted from the sub-pixel 13 is concentrated in the direction perpendicular to the substrate 11. The display panel 10 of this application has a first light-shielding layer 18 on its surface, which further absorbs and blocks the light outside the first light-transmitting opening 182, narrows the light-emitting viewing angle, realizes the privacy function, and at the same time reduces the probability of the light from the display panel 10 forming extra images on other side structures. Meanwhile, since the light emitted vertically from the sub-pixel 13 will not be blocked or absorbed by the separator 14 or the first light-shielding layer 18, the loss of direct light can be reduced, the brightness of direct light can be guaranteed, the luminous efficiency can be guaranteed, and the impact on service life and power consumption can be reduced.

[0035] Optionally, the width of the separator 14 in the second direction X gradually decreases along the first direction Z. Specifically, the cross-section of the separator 14 in the plane perpendicular to the substrate 11 is an isosceles trapezoid that is narrower at the top and wider at the bottom. The separator 14 with the above shape can ensure that the second electrode 133 covering the separator 14 is in close contact with the surface of the separator 14 without being broken, ensuring that the second electrode 133 corresponding to all sub-pixels 13 is a continuous film layer, and reducing the impedance introduced by the second electrode 133.

[0036] Optionally, continue reading Figure 1 In this embodiment, the display panel 10 further includes a light-transmitting layer 17 disposed between the pixel definition layer 12 and the first light-shielding layer 18. Specifically, the material of the light-transmitting layer 17 can be a transparent optical adhesive, and the thickness of the light-transmitting layer 17 is greater than or equal to 8 μm. The light-transmitting layer 17 increases the distance between the sub-pixel 13 and the first light-shielding layer 18, ensuring that the viewing angle of the light emitted from the sub-pixel 13 is smaller. Optionally, the display panel 10 further includes a touch layer 16 and an encapsulation layer 15. The touch layer 16 is disposed between the light-transmitting layer 17 and the pixel definition layer 12. Along the first direction Z, the touch layer 16 includes a first inorganic layer 161, a first metal layer 162, a second inorganic layer 163, a second metal layer 164, and a first organic layer 165 stacked sequentially. The encapsulation layer 15 is disposed between the touch layer 16 and the pixel definition layer 12. Along the first direction Z, the encapsulation layer 15 includes a first inorganic encapsulation layer 151, an organic encapsulation layer 152, and a second inorganic encapsulation layer 152 stacked sequentially.

[0037] Optionally, continue reading Figure 1The light-transmitting layer 17 has a light-focusing structure corresponding to the sub-pixel 13, which is used to focus the light emitted from the sub-pixel 13. The light-focusing structure includes a refractive surface, on which the light emitted from the sub-pixel 13 is refracted and focused. The light-focusing structure adjusts the emission direction of the light to be perpendicular or substantially perpendicular to the plane of the substrate 11, reducing the probability of the light being absorbed by the first light-shielding layer 18 and improving the light efficiency of the front display of the display panel 10. Optionally, the first light-shielding layer 18 also includes a light-shielding member 181 disposed in the first light-transmitting opening 182. The orthographic projection of the light-shielding member 181 on the substrate 11 at least partially overlaps with the orthographic projection of the separator 14 on the substrate 11. The light-shielding member 181 corresponds to the separator 14, further blocking some of the wide-view light emitted by the sub-pixel 13, narrowing the light-emitting angle of the sub-pixel 13, and concentrating the light emitted from the sub-pixel 13 in the direction perpendicular to the substrate 11, realizing the privacy function, and at the same time reducing the probability of the light from the display panel 10 forming extra images on other side structures. Meanwhile, since the light emitted from the sub-pixel 13 is emitted almost perpendicularly through the light-focusing structure, it is not blocked or absorbed by the light-shielding member 181, thereby reducing the loss of direct light, ensuring the brightness of direct light, ensuring high luminous efficiency, and reducing the impact on lifespan and power consumption. Furthermore, the orthographic projection of the light-shielding member 181 on the substrate 11 coincides with the orthographic projection of the separator 14 on the substrate 11, that is, the side edge of the light-shielding member 181 in the first direction X is flush with the side edge of the separator 14, minimizing the absorption of light.

[0038] Optionally, continue reading Figure 1The light-transmitting layer 17 includes a first light-transmitting sub-layer 171 and a second light-transmitting sub-layer 172 sequentially stacked in the first direction Z. The refractive index of the first light-transmitting sub-layer 171 is less than that of the second light-transmitting sub-layer 172. A through-hole 1711 is formed in the first light-transmitting sub-layer 171, and the opening area of ​​the through-hole 1711 gradually decreases along the direction from the first light-transmitting sub-layer 171 to the substrate 11. The second light-transmitting sub-layer 172 fills the through-hole 1711. The cross-section of the through-hole 1711 in the plane perpendicular to the substrate 11 is an isosceles trapezoid, and the trapezoid is wider at the top and narrower at the bottom. When the light emitted from the sub-pixel 13 passes through the interface (i.e., the refractive surface) of the first light-transmitting sub-layer 171 and the second light-transmitting sub-layer 172, the light is refracted at the interface and moves closer to the center of the through-hole 1711, making the light more focused. Simultaneously, light rays with larger angles first pass through the through-hole 1711 and strike the second phototransparent layer 172. When some of the light reaches the interface between the first phototransparent layer 171 and the second phototransparent layer 172 around the through-hole 1711, due to the greater refractive index of the second phototransparent layer 172 than the first phototransparent layer 171, total internal reflection occurs at this interface when the incident angle is too large, thus concentrating the light. Specifically, to ensure the focusing effect, the thickness of the first phototransparent layer 171 is greater than or equal to 4 μm; and / or, the thickness of the second phototransparent layer 172 is greater than or equal to 4 μm, and the angle between the interface between the first and second phototransparent layers 171 and the first phototransparent layer 171 facing away from the second phototransparent layer 172, i.e., the cone angle θ formed by the through-hole 1711 on the first phototransparent layer 171, is 30°-45°. In this embodiment, the surface of the second phototransparent layer 172 facing away from the first phototransparent layer 171 is a plane. Specifically, for ease of preparation, the materials of the first phototransparent layer 171 and the second phototransparent layer 172 are both negative adhesives, which facilitates exposure to form a cone angle θ.

[0039] Alternatively, see [link to relevant documentation] Figure 2 , Figure 2 This is a schematic diagram of another embodiment of the display panel of this application. Figure 1 The difference in the illustrated embodiment is that the surface of the second light-transmitting sublayer 172 facing away from the first light-transmitting sublayer 171 is not planar. The second light-transmitting sublayer 172 includes a lens portion 1721, which is disposed corresponding to the through hole 1711, and the surface of the lens portion 1721 facing away from the substrate 11 is a partially spherical surface that protrudes away from the substrate 11. Multiple lens portions 1721 form a microlens array, which can further focus light. Specifically, in order to ensure the focusing effect, the thickness of the lens portion 1721 is 8-24 μm.

[0040] Optionally, in one embodiment, the orthographic projection of the sub-pixel 13 onto the substrate 11 is rectangular, and the extending direction of the orthographic projection of the separator 14 onto the substrate 11 is parallel to the long side of the orthographic projection of the sub-pixel 13 onto the substrate 11. Specifically, as shown... Figure 3 As shown, the separator 14 (blocked by the light-shielding member 181, not shown), the light-shielding member 181, and the light-shielding layer 18 all extend along the third direction Y. The long side of the orthographic projection of the sub-pixel 13 on the substrate 11 extends along the third direction Y, and the short side extends along the second direction X. The green sub-pixel 13a and the red sub-pixel 13b are spaced apart along the third direction Y, the blue sub-pixel 13 is spaced apart from the green sub-pixel 13a and the red sub-pixel 13b along the second direction X, and a plurality of blue sub-pixels 13c are spaced apart along the third direction Y. The above arrangement allows the orthographic projection of the separator 14 on the substrate 11 to extend along the gap between two adjacent sub-pixels 13, and since the separator 14 divides the short side of the sub-pixel 13, the number of parts formed by the division of the sub-pixel 13 can be reduced, thereby reducing the impact on the luminous efficiency of the sub-pixel 13. Furthermore, the orthographic projection of the separator 14 on the substrate 11 divides the orthographic projection of the sub-pixel 13 on the substrate 11 into two parts with the same area. That is, the orthographic projection of the separator 14 on the substrate 11 coincides with the orthographic projection of the midline of the short side of the sub-pixel 13 on the substrate 11. The area of ​​the part formed by the separation of each sub-pixel 13 is the same, which further ensures the light-emitting effect.

[0041] In another embodiment, such as Figure 4 As shown, the extending direction of the separator 14 projected onto the substrate 11 is perpendicular to the long side of the sub-pixel 13 projected onto the substrate 11. This arrangement has a relatively small impact on the light emission of the sub-pixel 13. In other embodiments, the sub-pixel 13 can also be other shapes, such as rhombuses or circles. The extending direction of the separator 14 can also intersect with the edge extending direction of the sub-pixel 13.

[0042] Alternatively, in another embodiment, see [reference] Figure 5 , Figure 5This is a schematic diagram of another embodiment of the display panel of this application. The display panel 10 also includes a second light-shielding layer 19, disposed on the side of the light-transmitting layer 17 facing the pixel definition layer 12. Specifically, the material of the light-transmitting layer 17 can be a transparent optical adhesive. The light-transmitting layer 17 includes a first light-transmitting sub-layer 171 and a second light-transmitting sub-layer 172 stacked along the first direction Z. Due to the different refractive indices of the two layers, when the light emitted from the sub-pixel 13 passes through the interface between the first light-transmitting sub-layer 171 and the second light-transmitting sub-layer 172, the light is refracted at the interface and moves closer to the center of the first light-transmitting opening 182, making the light more focused. The thickness of the light-transmitting layer 17 is greater than or equal to 8 μm. The light-transmitting layer 17 increases the distance between the sub-pixel 13 and the first light-shielding layer 18, ensuring that the viewing angle of the light emitted from the sub-pixel 13 is smaller. The second light-shielding layer 19 is provided with a second light-transmitting opening 191, and the orthographic projection of the second light-transmitting opening 191 on the substrate 11 at least partially overlaps with the orthographic projection of the sub-pixel 13 on the substrate 11. In this embodiment, two light-shielding layers are respectively set on the upper and lower sides of the light-transmitting layer 17. The double light-shielding achieves the blocking and absorption of light from a wide viewing angle, reducing light leakage from a wide viewing angle.

[0043] Furthermore, the orthographic projections of the first light-transmitting opening 182 and the second light-transmitting opening 191 on the substrate 11 coincide. That is, the first light-transmitting opening 182, the second light-transmitting opening 191, and the pixel opening 121 are completely aligned in the first direction Z, limiting the emission angle of the light so that the light can only be emitted perpendicularly or substantially perpendicularly.

[0044] Alternatively, in another embodiment, see [reference] Figure 6 , Figure 6 This is a schematic diagram of another embodiment of the display panel of this application. Figure 5 Unlike the embodiments shown, the light-transmitting layer 17 in this embodiment includes a lens portion 1721, and multiple lens portions 1721 form a microlens array, which can further focus the light.

[0045] This application also provides a display device, including the display panel 10 in any of the above embodiments. The display device can be a mobile phone, tablet computer, vehicle display screen, etc. For mobile phones and tablet computers, the display device provided by this application has good privacy protection performance and ensures light efficiency when viewed directly; for vehicle display screens, the display device provided by this application can more strictly control the direction of light emission to reduce the formation of images on the windshield or side windows of the car, thereby improving driving safety.

[0046] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
