Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a display panel and a display device. Background Technology

[0002] Organic light-emitting diode (OLED) display panels currently have advantages such as high image quality, energy saving, small thickness and wide application range, and are widely used in various consumer electronic products such as mobile phones, televisions, laptops, and desktop computers.

[0003] However, the performance and manufacturing process of current display devices need to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a display panel and a display device to improve the performance of the display device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, this application provides a display panel, which includes a substrate, a light-emitting device layer and a lens structure layer. The light-emitting device layer is located on one side of the substrate and includes a plurality of light-emitting units. The lens structure layer is located on the side of the light-emitting device layer away from the substrate and includes a plurality of microlenses. The orthographic projection of a light-emitting unit on the substrate overlaps with the orthographic projection of a microlens on the substrate. The relative positions of the centers of the orthogonal projections of at least two light-emitting units onto the substrate and the centers of the orthogonal projections of the corresponding microlenses onto the substrate are different.

[0006] Through the above technical solution, the microlenses in the lens structure layer can focus the light emitted by the light-emitting units, which is beneficial to improving the display effect. Furthermore, the relative positions of the centers of the orthographic projections of at least two light-emitting units onto the substrate and the centers of the orthographic projections of the corresponding microlenses onto the substrate are different. This allows the light emitted from the microlenses corresponding to at least two light-emitting units to have different emission angles. In other words, the display panel provided in this application contains microlenses with different light emission angles, which helps improve the uniformity of the emitted light from the display panel, thereby improving the display uniformity.

[0007] Therefore, the display panel provided in this application is beneficial to improving the performance of the display device.

[0008] In some embodiments, the center of the orthogonal projection of at least one light-emitting unit on the substrate coincides with the center of the orthogonal projection of the corresponding microlens on the substrate, and the center of the orthogonal projection of at least one light-emitting unit on the substrate and the center of the orthogonal projection of the corresponding microlens on the substrate are spaced apart. And / or, the center of the orthogonal projection of at least two light-emitting units on the substrate is at a different distance from the center of the orthogonal projection of the corresponding microlens on the substrate.

[0009] And / or, the center of the orthogonal projection of at least one light-emitting unit on the substrate is spaced apart from the center of the orthogonal projection of the corresponding microlens on the substrate.

[0010] In this way, the relative positions of the center of the orthographic projection of at least two light-emitting units on the substrate and the center of the orthographic projection of the corresponding microlens on the substrate are different. This is beneficial to make the light emitted from the microlenses corresponding to at least two light-emitting units have different emission angles, thereby improving the uniformity of the light emitted from the display panel and thus improving the display uniformity of the display panel.

[0011] In some embodiments, the center of the orthographic projection of at least two light-emitting units with the same emission color onto the substrate is at a different relative position than the center of the orthographic projection of the corresponding microlens onto the substrate.

[0012] In this way, the light emitted from the microlenses corresponding to at least two light-emitting units with the same color has different emission angles, which helps to improve the uniformity of the light emitted from the display panel, thereby improving the display uniformity of the display panel.

[0013] Optionally, the center of the orthographic projection of at least two adjacent light-emitting units with the same color on the substrate is at a different relative position than the center of the orthographic projection of the corresponding microlens on the substrate.

[0014] In this way, the light emitted from the microlenses corresponding to at least two adjacent light-emitting units with the same color emission has different emission angles, which helps to improve the uniformity of the light emitted from the display panel, thereby improving the display uniformity of the display panel.

[0015] In some embodiments, the light-emitting units are arranged in an array along a first direction and a second direction, and the center of the orthogonal projection of at least one microlens on the substrate is offset relative to the center of the orthogonal projection of the light-emitting unit on the substrate along the first direction or the second direction. The first direction and the second direction are perpendicular to the thickness direction of the substrate, and the first direction is perpendicular to the second direction. Alternatively, the microlenses are arranged in an array along the first and second directions, and the center of the orthogonal projection of at least one light-emitting unit on the substrate is offset relative to the center of the orthogonal projection of the microlens on the substrate along the first or second direction. The first and second directions are perpendicular to the thickness direction of the substrate, and the first direction is perpendicular to the second direction.

[0016] Through the above technical solution, the light-emitting units can be arranged in a regular manner. The center of the orthogonal projection of at least one microlens on the substrate is offset relative to the center of the orthogonal projection of the light-emitting unit on the substrate along a first direction or a second direction. The irregular arrangement of at least one microlens is beneficial for the light emitted from the microlenses corresponding to different light-emitting units to have different emission angles, thereby improving the uniformity of the light emitted from the display panel and thus improving the display uniformity of the display panel.

[0017] Furthermore, the microlenses can be arranged in a regular pattern. The center of the orthogonal projection of at least one light-emitting unit on the substrate is offset relative to the center of the orthogonal projection of the microlens on the substrate along a first direction or a second direction. The irregular arrangement of at least one light-emitting unit is beneficial because the light emitted from the microlenses corresponding to different light-emitting units has different emission angles, which helps to improve the uniformity of the light emitted from the display panel, and thus helps to improve the display uniformity of the display panel.

[0018] Optionally, the light-emitting device layer includes multiple light-emitting unit groups arranged in an array along the first direction and the second direction, and each light-emitting unit group includes multiple light-emitting units; In the same light-emitting unit group, the relative positions of the centers of the orthogonal projections of at least two light-emitting units on the substrate and the centers of the orthogonal projections of the corresponding microlenses on the substrate are different.

[0019] Through the above technical solution, in the same light-emitting unit group, the light emitted from the microlenses corresponding to at least two light-emitting units has different emission angles, which helps to improve the uniformity of the emitted light from the display panel, thereby improving the display uniformity of the display panel. Furthermore, the light-emitting unit groups can be arranged regularly, which helps to reduce the fabrication difficulty of the light-emitting units.

[0020] In some embodiments, the light-emitting device layer includes multiple light-emitting unit groups arranged in an array along a first direction and a second direction. Each light-emitting unit group includes multiple light-emitting unit subgroups, and each light-emitting unit subgroup includes a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit, each emitting a different color. The first and second light-emitting units are arranged along the second direction, and the third light-emitting unit is located on one side of the first and second light-emitting units along the first direction. This facilitates the formation of multiple irregularly arranged light-emitting units within the same light-emitting unit group, thereby promoting uniform light emission from the light-emitting device layer.

[0021] Optionally, the light-emitting unit group includes four first light-emitting units, four second light-emitting units, and four third light-emitting units; or, the light-emitting unit group includes six first light-emitting units, six second light-emitting units, and six third light-emitting units; or, the light-emitting unit group includes nine first light-emitting units, nine second light-emitting units, and nine third light-emitting units.

[0022] In some implementations, the intersection of the microlenses is located between two opposing surfaces of the corresponding light-emitting unit in the thickness direction of the substrate, which helps to improve the focusing effect of the microlenses.

[0023] Optionally, the light-emitting unit includes a first electrode, a light-emitting layer, and a second electrode arranged sequentially along the direction away from the substrate. The intersection of the microlenses is located between the first electrode and the second electrode of the corresponding light-emitting unit, which helps to further improve the focusing effect of the microlenses.

[0024] In some embodiments, the light-emitting unit includes a first electrode, a light-emitting layer, and a second electrode arranged sequentially in a direction away from the substrate, and the second electrode has a plurality of first protrusions on the side surface away from the substrate.

[0025] Through the above technical solution, the first protrusion can increase the light-emitting area on the side of the second electrode away from the substrate, which is beneficial to increasing the amount and range of light emitted, thereby improving the luminous efficiency of the light-emitting unit and thus improving the display effect of the display panel.

[0026] Optionally, the light-emitting layer has a plurality of second protrusions on the side surface opposite to the substrate, and the orthographic projection of a second protrusion on the substrate overlaps with the orthographic projection of a first protrusion on the substrate.

[0027] In this way, the second protrusion can increase the light-emitting area on the side of the light-emitting layer away from the substrate, which is beneficial to increasing the amount and range of light emitted, thereby improving the luminous efficiency of the light-emitting unit and thus improving the display effect of the display panel. Furthermore, by providing a second protrusion on the surface of the light-emitting layer away from the substrate, the display panel provided in this application can form a first protrusion during the fabrication of the second electrode.

[0028] Optionally, the surface of the first electrode facing away from the substrate is provided with a plurality of third protrusions, and the orthographic projection of one third protrusion on the substrate overlaps with the orthographic projection of one second protrusion on the substrate.

[0029] In this way, the display panel provided in this application can form the second protrusion during the fabrication of the light-emitting layer by providing the second protrusion on the side surface of the first electrode away from the substrate.

[0030] Optionally, the display panel further includes a protruding structure layer located between the first electrode and the substrate. The protruding structure layer includes a plurality of bump groups, each bump group including a plurality of bumps. The orthographic projection of a bump group on the substrate is located within the orthographic projection of a light-emitting layer on the substrate, and the orthographic projection of a third protrusion on the substrate overlaps with the orthographic projection of a bump on the substrate.

[0031] In this way, the display panel provided in this application can form a third protrusion during the fabrication of the first electrode by setting a protruding structural layer.

[0032] In some embodiments, the display panel provided in this application further includes a filter layer, which is located on the side of the light-emitting unit away from the substrate, and a lens structure layer is located on the side of the filter layer away from the substrate. The filter layer includes multiple filter sections, and the orthographic projection of a light-emitting unit on the substrate overlaps with the orthographic projection of a filter section on the substrate, and the orthographic projections of at least two adjacent filter sections on the substrate overlap.

[0033] In this way, the overlapping orthographic projections of adjacent filter elements on the substrate can block the large-angle light from the light-emitting unit, thereby reducing crosstalk between light emitted by adjacent light-emitting units.

[0034] Optionally, the orthographic projection of the light-emitting unit on the substrate is located within the orthographic projection of the corresponding filter on the substrate, so that the filter can filter the light emitted by the light-emitting unit.

[0035] Optionally, the display panel provided in this application further includes a light-shielding layer located on the side of the light-emitting unit facing away from the substrate. A light-filtering layer is disposed on the same side of the light-shielding layer facing away from the substrate. The light-shielding layer includes multiple light-shielding portions, and at least a portion of these portions have their orthographic projection on the substrate located between the orthographic projections of two adjacent light-emitting units on the substrate. The light-shielding layer effectively blocks large-angle light from the light-emitting units, thereby reducing crosstalk between adjacent light-emitting units.

[0036] Optionally, the overlapping portion of the orthographic projection of two adjacent filter portions on the substrate overlaps with the orthographic projection of the light-shielding portion on the substrate, which helps to further reduce crosstalk of light emitted by adjacent light-emitting units.

[0037] In some embodiments, the light-emitting unit includes a first electrode, a light-emitting layer, and a second electrode sequentially disposed along a direction away from the substrate. The display panel also includes a pixel definition layer located on the side of the first electrode away from the substrate. The pixel definition layer includes a plurality of pixel openings that expose the first electrode. At least a portion of the light-emitting layer is located within the pixel openings, and the orthographic projection of the pixel openings onto the substrate is an octagon.

[0038] This helps to increase the aperture area of ​​the pixel, which in turn helps to improve the luminous efficiency and thus improve the display effect of the display panel.

[0039] Secondly, this application provides a display device that includes the display panel of any of the above embodiments.

[0048] Currently, display panels have advantages such as high image quality, energy saving, small thickness and wide application range, and are widely used in electronic products such as mobile phones, computers, and wearable devices. The display effect of the display panel has a significant impact on the performance of electronic products.

[0049] In related technologies, the light-emitting units of the display panel and the microlenses located on the light-emitting side of the light-emitting units are arranged in a regular array. This can lead to uneven dispersion of the emitted light, affecting the uniformity of light emission of the display panel, thereby affecting the display effect of the display panel and consequently affecting the performance of the display device.

[0050] To address the aforementioned technical problems, embodiments of this application provide a display panel and a display device.

[0051] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a display panel 100, which can be an organic light-emitting diode (OLED). OLED (Emitting Diode) display panel 100 or Micro LED / μLED (Micro Light Emitting Diode) display panel 100.

[0052] The display panel 100 provided in this application embodiment includes a substrate 10, which includes a display area AA and a non-display area NA, with the non-display area NA surrounding at least a portion of the display area AA.

[0053] Please continue reading. Figure 3 and Figure 5 and combined Figures 5 to 14 The display panel 100 provided in this application embodiment includes a substrate 10, a light-emitting device layer and a lens structure layer 75. The light-emitting device layer is located on one side of the substrate 10 and includes a plurality of light-emitting units. The lens structure layer 75 is located on the side of the light-emitting device layer away from the substrate 10 and includes a plurality of microlenses 751. The orthographic projection of a light-emitting unit on the substrate 10 overlaps with the orthographic projection of a microlens 751 on the substrate 10.

[0054] Among them, the relative positions of the centers of the orthogonal projections of at least two light-emitting units on the substrate 10 and the centers of the orthogonal projections of the corresponding microlens 751 on the substrate 10 are different.

[0055] Through the above technical solution, the microlenses 751 in the lens structure layer 75 can focus the light emitted by the light-emitting units, which is beneficial to improving the display effect. Furthermore, the relative positions of the centers of the orthographic projections of at least two light-emitting units onto the substrate 10 and the centers of the orthographic projections of the corresponding microlenses 751 onto the substrate 10 are different. This allows the light emitted from the microlenses 751 corresponding to at least two light-emitting units to have different emission angles. In other words, the display panel 100 provided in this embodiment has microlenses 751 with different light emission angles, which helps improve the uniformity of the emitted light from the display panel 100, thereby improving the display uniformity of the display panel 100.

[0056] Therefore, the display panel 100 provided in this application embodiment is beneficial to improving the performance of the display device.

[0057] In some embodiments, the center of the orthogonal projection of at least one light-emitting unit on the substrate 10 coincides with the center of the orthogonal projection of the corresponding microlens 751 on the substrate 10, and the center of the orthogonal projection of at least one light-emitting unit on the substrate 10 and the center of the orthogonal projection of the corresponding microlens 751 on the substrate 10 are spaced apart.

[0062] In some other embodiments, the center of the orthogonal projection of at least two light-emitting units on the substrate 10 is spaced apart from the center of the orthogonal projection of the corresponding microlens 751 on the substrate 10, and the center of the orthogonal projection of at least one light-emitting unit on the substrate 10 is spaced apart from the center of the orthogonal projection of the corresponding microlens 751 on the substrate 10 in different directions.

[0064] In this way, the relative positions of the center of the orthographic projection of at least two light-emitting units on the substrate 10 and the center of the orthographic projection of the corresponding microlens 751 on the substrate 10 are different. This is beneficial to make the light emitted from the microlens 751 corresponding to at least two light-emitting units have different emission angles, thereby improving the uniformity of the light emitted from the display panel 100, and further improving the display uniformity of the display panel 100.
