Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) is an optoelectronic technology that uses organic semiconductor materials to produce reversible color changes under current drive to achieve colorful display. OLED display panels have the advantages of lightness, high brightness, active light emission, low energy consumption, wide viewing angle, fast response, flexibility, and wide operating temperature range, and are widely favored in the field of display panels. At present, the conventional production method of OLED display panels is to limit the material evaporation area through a metal mask (Fine Metal Mask, FMM), and then complete it through light emission production and TFE packaging technology (Thin Film Encapsulation).

[0003] However, under a specific material system, the luminous efficiency of the luminescent material is fixed, and the light output of the product at the normal viewing angle is basically stable. If you want to increase the light output, you need to increase the driving current of the device to achieve the increase in the light output at the normal viewing angle and achieve the display brightness required by the product. However, the consequence of doing so is that the overall power consumption of the product will increase, which is something that product developers do not want to see. Therefore, before a new OLED material device system is developed, avoiding an increase in product power consumption while ensuring display brightness is a major competitive advantage of display products. Summary of the invention

DETAILED DESCRIPTION

[0025] It should be understood that the terms used herein, the specific structures and functional details disclosed are only for describing specific embodiments and are representative, but the present application can be implemented in many alternative forms and should not be construed as being limited to only the embodiments described herein.

[0026] In addition, unless otherwise clearly specified or limited, "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internally connected between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In OLED display panels, since the luminous efficiency of the material is fixed, the amount of light emitted from the product at the normal viewing angle is basically stable. To increase the amount of light emitted at the normal viewing angle and the display brightness, it is necessary to increase the driving current. However, this will lead to an increase in the power consumption of the display product. Some current directions are to make the two situations compatible and avoid an increase in product power consumption while ensuring the display brightness.

[0028] Figure 1 is a schematic diagram of a display panel, such as Figure 1 As shown, the display panel 30 is an OLED panel, including a substrate 31, a light-emitting functional layer 33, a pixel definition layer 32, an insulating layer 39, a packaging structure 40 and a micro-prism structure 50, etc. The light-emitting functional layer 33 and the pixel definition layer 32 are arranged in parallel on the substrate 31, the insulating layer 39 is located on the light-emitting functional layer 33 and the pixel definition layer 32, the packaging structure 40 and the micro-prism structure 50 are located on the light-emitting functional layer 33. The micro-prism structure 50 is used to gather the light emitted by the light-emitting functional layer 33 to improve the light output brightness of the display panel 30.

[0029] Specifically, the encapsulation structure 40 includes a flat layer 41, a first encapsulation layer 42, and a second encapsulation layer 43. The flat layer 41 covers the light-emitting functional layer 33 and the pixel definition layer 32. The first encapsulation layer 42 is arranged on the flat layer 41, and the second encapsulation layer 43 is arranged on the first encapsulation layer 42. The flat layer 41 has a large thickness and is used to form a flat surface. The first encapsulation layer 42 and the second encapsulation layer 43 can be one of an inorganic insulating layer and an organic insulating layer, that is, the first encapsulation layer 42 is an inorganic insulating layer and the second encapsulation layer 43 is an organic insulating layer; or the first encapsulation layer 42 is an organic insulating layer and the second encapsulation layer 43 is an inorganic insulating layer. Through the combined design of the first encapsulation layer 42 and the second encapsulation layer 43, the functional devices in the display panel 30 can be better protected.

[0030] The micro-prism structure 50 may be a layer of high-refractive and high-transparent film layer, and the micro-prism structure 50 is formed on the second encapsulation layer 43 to refract and focus light. Alternatively, the micro-prism structure 50 is a combined structure of a focusing lens 37 and a high-refractive and high-transparent film layer 51. Specifically, a refractive film layer is first formed on the second encapsulation layer 43, and then the refractive film layer is patterned to obtain a focusing lens 37; and then a high-refractive and high-transparent film layer 51 is formed on the focusing lens 37, and the focusing lens 37 and the high-refractive and high-transparent film layer 51 are used to focus the light emitted by the light-emitting functional layer 33, thereby increasing the amount of light emitted from the front of the display panel 30, reducing the pixel current density to a certain extent, and effectively extending the service life of the product while optimizing the power consumption of the product.

[0031] The focusing lens 37 is located on the pixel definition layer 32 and refracts the light in the non-pixel area to the pixel area, so the amount of light in the original pixel area will not be reduced and the display uniformity effect will not be affected.

[0032] However, the above design easily leads to an increase in the thickness of the display panel 30 , and the light focusing effect needs to be improved. Based on this, the embodiment of the present application provides a new type of display panel.

[0033] like Figure 2As shown, as a new type of display panel provided in an embodiment of the present application, the display panel 30 includes a substrate 31, a pixel definition layer 32, a light-emitting functional layer 33, a first microprismatic structure layer 34, a second microprismatic structure layer 35 and an inorganic packaging layer 36, wherein the pixel definition layer 32 is arranged on the substrate 31, and the pixel definition layer 32 is divided into a plurality of partitions, and the interior of each partition is hollowed out to form a pixel area; the light-emitting functional layer 33 is arranged in the plurality of pixel areas, the first microprismatic structure layer 34 is arranged on the light-emitting functional layer 33, the second microprismatic structure layer 35 is arranged on the first microprismatic structure layer 34, and the inorganic packaging layer 36 is arranged on the second microprismatic structure layer 35; wherein the first microprismatic structure layer 34 and the second microprismatic structure layer 35 are both organic packaging structures, and the refractive index of the second microprismatic structure layer 35 is greater than the refractive index of the first microprismatic structure layer 34.

[0034] Among them, the pixel definition layer 32 (PDL) is used to define and limit the shape and size of the pixel to ensure that each pixel can work correctly. Specifically, the PDL can achieve accurate alignment and positioning of the pixels, ensure isolation between pixels, prevent crosstalk, and reduce color mixing between adjacent pixels. The pixel definition layer 32 is mainly used for AMOLED evaporation before the photolithography process of the polyimide (PSPI) material. In the embodiment of the present application, the pixel definition layer 32 also includes a support structure 321 (PS) located above it.

[0035] The light-emitting functional layer 33 specifically includes an anode, a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting auxiliary layer (RGB Prime), an organic light-emitting layer (EML), a hole blocking layer (HBL), an electron transport layer (ETL), an electron injection layer (EIL) and a cathode. Among them, the organic light-emitting layer is used to convert electrons into light sources, and other organic structures are used to help electrons and holes flow smoothly.

[0036] The inorganic encapsulation layer 36 can be a single-layer structure, or a two-layer or three-layer film structure. When the inorganic encapsulation layer 36 is a two-layer stacked structure, it can be composed of an inorganic insulating layer and an organic insulating layer stacked. Of course, the display panel 30 also includes other structures such as thin film transistors and an insulating layer 39, which will not be described in detail here.

[0037] In the embodiment of the present application, a first microprism structure layer 34 and a second microprism structure layer 35 are added to the light-emitting functional layer 33, and the refractive index of the second microprism structure layer 35 is greater than the refractive index of the first microprism structure layer 34, so that the light emitted by the light-emitting functional layer 33 converges toward the middle area of ​​the display panel 30 after passing through the first microprism structure layer 34 and the second microprism structure layer 35, thereby increasing the brightness of the light emitted from the front of the display panel 30. In this way, while ensuring the brightness of the light emitted from the front of the display panel 30, it is possible to avoid increasing the brightness of the light-emitting functional layer 33, so as to reduce the power consumption of the product, thereby improving the market competitiveness of the product. Moreover, the first microprism structure layer 34 and the second microprism structure layer 35 are themselves the packaging structure of the display panel 30, and the embodiment of the present application does not add an additional film layer structure, so it will not cause the thickness of the display panel 30 to increase.

[0038] And relative to Figure 1 In the solution, the first micro-prismatic structure layer 34 is replaced by the embodiment of the present application. Figure 1 The flat layer 41 in the embodiment of the present invention is omitted, and the thick flat layer 41 structure is omitted, which is beneficial to reduce the overall thickness of the display panel 30. Moreover, since the first micro-prism structure layer 34 and the second micro-prism structure layer 35 can deflect the light at the same time, and the second micro-prism structure layer 35 close to the light exit surface has a greater deflection effect on the light, the light is more concentrated. Therefore, the prism structure in the embodiment of the present application is relatively Figure 1 The prism structure in the lens has a better light focusing effect.

[0039] Specifically, the refractive index of the first micro-prismatic structure layer 34 is between 1.4 and 1.6 to meet the refractive index requirement of the low-refractive material in the micro-prismatic structure 50, and the refractive index of the second micro-prismatic structure layer 35 is between 1.7 and 2.0. After testing, the inventors found that when the above design is adopted, the light emitted by the light-emitting functional layer 33 can be more concentrated toward the pixel area, greatly reducing the light emitted to the pixel definition layer 32 area, thereby achieving the purpose of further improving the focusing effect.

[0040] Further, such as Figure 3 As shown, the display panel 30 further includes a plurality of condensing lenses 37 , which are disposed one by one on the partitions formed by the pixel definition layer 32 , and the condensing lenses 37 are located between the first micro-prism structure layer 34 and the second prism structure layer.

[0041] The embodiment of the present application further adds a condenser lens 37 to focus the light incident on the pixel definition layer 32 area to the pixel area, thereby further improving the brightness of the pixel area.

[0042] Among them, the partition is a ring structure surrounding the corresponding pixel area, and the focusing lens 37 can be located on only one side of the partition to fully reflect the light on one side of the pixel; or, the focusing lens 37 can be located on only the left and right sides or the upper and lower sides of the partition to fully reflect the light on both sides of the pixel; or, the focusing lens 37 can be located on three or four sides of the partition to fully reflect the light in more areas, thereby further increasing the amount of light in the pixel area.

[0043] Optionally, the orthographic projection of the condenser lens 37 on the substrate 31 covers the orthographic projection of the corresponding partition on the substrate 31. Through this design, the condenser lens 37 can receive more light and converge more light to the pixel area. Even, the orthographic projection of the condenser lens 37 on the substrate 31 can also partially overlap with the orthographic projection of the light-emitting functional layer 33 on the substrate 31 to fully reflect more light.

[0044] In the embodiment of the present application, after the pixel definition layer 32, the light-emitting functional layer 33, and the insulating layer 39 above the two are designed, the first micro-prism structure layer 34 is made to ensure the leveling of the device film structure. After the first micro-prism structure layer 34 is leveled and solidified, the focusing lens 37 can be made on the first micro-prism structure layer 34 by photolithography; then the second micro-prism structure layer 35 is made to complete the production of all micro-prism structures 50, and the first micro-prism structure layer 34, the focusing lens 37 and the second micro-prism structure layer 35 are functionalized as a whole. After the above film layers are made, the inorganic encapsulation layer 36 is made, and finally the protective film layer process is completed in a conventional manner.

[0045] The height of the first micro-prism structure layer 34 is at least greater than the height of the top of the support structure 321 in the pixel definition layer 32 , and the leveling of the film structure is ensured.

[0046] The manufacturing process of the condenser lens 37 is as follows: a film layer is deposited on the first micro-prism structure layer 34, and then patterning is performed, that is, on the basis of the opening of the pixel definition layer 32, an appropriate opening is expanded, generally by about 1-3 μm, specifically by 2 μm, to obtain the condenser lens 37. The refractive index of the condenser lens 37 is between 1.4 and 1.6, which meets the refractive index requirement of the low-refractive material in the micro-prism structure 50. Through the above-mentioned design of the first micro-prism structure layer 34 and the condenser lens 37, the low-refractive pattern structure of the micro-prism structure 50 can be obtained.

[0047] In the process of forming the second micro-prismatic structure layer 35, the photolithography process can be directly used to form a high-refractive and high-transparent material to complete the production of the second micro-prismatic structure layer 35. Specifically, high-refractive particles (such as ZrO2, etc.) can be mixed when depositing low-refractive materials to achieve high refraction while ensuring that the transmittance does not change much. Of course, high-refractive index materials can also be directly deposited to form the second micro-prismatic structure layer 35.

[0048] The embodiment of the present application mainly adjusts the structure of the thick light-emitting layer so that in addition to the packaging and light-emitting functions, it also adds an additional light-emitting adjustment function. Under normal circumstances, the second micro-prismatic structure layer 35 is formed by printing, and the thickness is generally about 30 μm. If photolithography is used, the thickness of the second micro-prismatic structure layer 35 can be reduced to about 5 μm. If the micro-prismatic functionalization of the light-emitting layer is achieved by photolithography, that is, the combination design of the first micro-prismatic structure layer 34, the focusing lens 37 and the second micro-prismatic structure layer 35, the overall thickness can be reduced by about 5 microns, and the thinning thickness is considerable.

[0049] In the embodiment of the present application, the thickness of the second micro-prismatic structure layer 35 is less than the thickness of the first micro-prismatic structure layer 34. Firstly, the first micro-prismatic structure layer 34 needs to be higher than the top of the pixel definition layer 32, not only to achieve fine-tuning of the light emitted by the light-emitting functional layer 33, but also to make the top flat, so it has certain thickness requirements; secondly, to avoid the distance between the pixel definition layer 32 and the top of the first micro-prismatic structure layer 34 being too large, so that part of the light is irradiated to the bottom of the focusing lens 37 and reflected to the pixel definition layer 32, causing light loss; thirdly, the thickness of the second micro-prismatic structure layer 35 is greater than the thickness of the focusing lens 37. The combination of the second micro-prismatic structure layer 35 and the focusing lens 37 can make most of the light reach the pixel area, so the second micro-prismatic structure layer 35 does not need to be set to a large thickness to meet the requirements of forming a focusing, and increase the brightness of the light emitted from the front of the display panel 30.

[0050] It should be noted that, since the first microprismatic structure layer 34 and the second microprismatic structure layer 35 are not film layers with uniform thickness, the thickness mentioned here refers to the maximum thickness of the first microprismatic structure layer 34 and the maximum thickness of the second microprismatic structure layer 35 .

[0051] In some embodiments, Figure 4As shown, a plurality of grooves 341 are provided on one side of the first micro-prismatic structure layer 34 facing the second micro-prismatic structure layer 35, and a plurality of protrusions 351 are provided on one side of the second micro-prismatic structure layer 35 facing the first micro-prismatic structure layer 34. The material of the protrusions 351 is the same as that of the second micro-prismatic structure layer 35, that is, the protrusions 351 are part of the first micro-prismatic structure layer 34. The protrusions 351 and the grooves 341 are in one-to-one correspondence, and the contact surface between the first micro-prismatic structure layer 34 and the second micro-prismatic structure layer 35 is uneven.

[0052] The embodiment of the present application improves the contact surface between the first micro-prismatic structure layer 34 and the second micro-prismatic structure layer 35, so that the angle of the light emitted by the light-emitting functional layer 33 has more directions of deflection after being emitted from the uneven surface of the first micro-prismatic structure layer 34; at this time, after these light rays from different directions enter through the uneven surface of the second micro-prismatic structure layer 35, they will be more evenly mixed and emitted outward, avoiding the light rays refracted by the first micro-prismatic structure layer 34 and the second micro-prismatic structure layer 35 from being deflected toward the area where the pixel definition layer 32 is located, and at the same time making the light quantity in each place more uniform. In addition, the embodiment of the present application is also combined with the design of a condenser lens 37, which converges the light deflected to the area where the pixel definition layer 32 is located to the pixel area through the condenser lens 37, thereby further improving the brightness of the pixel area while ensuring the uniform light quantity in the pixel area.

[0053] Moreover, in the embodiment of the present application, the first micro-prismatic structure layer 34 and the second micro-prismatic structure layer 35 are directly bonded to each other without a gap, thereby preventing light from being consumed between the first micro-prismatic structure layer 34 and the second micro-prismatic structure layer 35 or generating reverse light deflection.

[0054] Furthermore, in the thickness direction of the display panel 30, the groove wall section of the groove 341 is arc-shaped, the outer wall section of the protrusion 351 is arc-shaped, and the groove 341 and the protrusion 351 are seamlessly attached; specifically, the groove wall section of the groove 341 and the outer wall section of the protrusion 351 are both arc-shaped. Through this setting, the groove 341 in the first micro-prismatic structure layer 34 also plays the role of a concave mirror, dispersing the light emitted by the light-emitting functional layer 33; and the protrusion 351 in the second micro-prismatic structure layer 35 plays the role of a convex mirror, and the second micro-prismatic structure layer 35 gathers the incident light toward the pixel area, making the brightness of the pixel area higher.

[0055] It should be noted that, since in the embodiment of the present application, the height of the first micro-prismatic structure layer 34 is relatively small and is close to the height of the pixel definition layer 32, the first micro-prismatic structure layer 34 is not suitable for setting the groove 341 in the pixel definition layer 32 area. In the scheme with the focusing lens 37, the first micro-prismatic structure layer 34 is not in direct contact with the second micro-prismatic structure layer 35 in the pixel definition layer 32 area, so the first micro-prismatic structure layer 34 is also not provided with the groove 341 in the pixel definition layer 32 area. Therefore, the groove 341 and the protrusion 351 will only be provided directly above the light-emitting functional layer 33, that is, the groove 341 and the protrusion 351 will only be provided in the pixel area, and will only converge the light toward the pixel area, and will not converge the light to the area where the pixel definition layer 32 is located, so that the light output brightness of the pixel area can be guaranteed.

[0056] In some embodiments, Figure 5 and Figure 6 As shown, the display panel 30 includes a plurality of micro prisms 38 , which are disposed on the surface of the condenser lens 37 , and the apex angles of the plurality of micro prisms 38 are perpendicular to the inorganic encapsulation layer 36 .

[0057] The embodiment of the present application adds a plurality of micro prisms 38 on the surface of the focusing lens 37. The micro prisms 38 adjust the light angle for the light incident on the focusing lens 37 from different angles, thereby further ensuring that the light incident on the focusing lens 37 has more opportunities to be totally reflected, thereby achieving total reflection of light at more angles and improving the brightness of the light output.

[0058] Among them, a plurality of the micro prisms 38 are at least arranged on both sides of the condenser lens 37. As an embodiment, the micro prisms 38 are only arranged on both sides of the condenser lens 37, so that a highly stepped array of micro prisms 38 is formed on both sides of the condenser lens 37. As another embodiment, these micro prisms 38 are simultaneously arranged on both sides of the condenser lens 37 and on one side of the condenser lens 37 facing the second micro prism structure layer 35, that is, the micro prisms 38 are distributed in an array along the edge of the condenser lens 37. Regardless of which embodiment is used, more light can be fully reflected.

[0059] Specifically, on both sides of the condenser lens 37, along the direction from the substrate 31 toward the inorganic encapsulation layer 36, the topographic heights of the plurality of micro-prisms 38 gradually increase. By such an arrangement, even if some angles of light pass through the first micro-prism 38 (the micro-prism 38 with the lowest height), full reflection cannot occur because the angle is not enough, but after being modulated by subsequent micro-prisms 38 of different heights, the full reflection condition can be finally achieved.

[0060] like Figure 7As shown, an embodiment of the present application further provides a display device, wherein the display device 10 includes a driving circuit 20 and a display panel 30 as described above, wherein the driving circuit 20 drives the display panel 30, and the display device 10 can reduce product power consumption and improve market competitiveness while ensuring display brightness.

[0061] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
