[0002] VR (Virtual Reality) technology and VR equipment have developed rapidly in the past two years, and the demand for VR technology in various industries has been growing. However, in terms of user experience, there are still problems such as poor display effect, insufficient battery life, and insufficient supporting content. The poor display effect is mainly due to the fact that in VR devices, the distance between the human eye and the display screen is shortened, and the optical path contains a magnifying lens, so that the human eye can directly see the boundary between the luminous area and the non-luminous area of ​​the pixel point of the display screen, just like looking at something through a screen window, so it is often called the Screen Door Effect (SDE).

[0003] Among the screen types used in existing VR devices, fast-LCD, WOLED and Micro-OLED are the majority, and RGB-OLED types are very rare, mainly because the screen door effect of RGB-OLED is more obvious. Summary of the invention

[0023] In a feasible implementation, the display panel further includes a packaging layer, and the second reflective structure is located on a side of the packaging layer away from the array substrate.

[0024] In a feasible implementation, the display panel further includes a protective layer, which is located on a side of the encapsulation layer away from the array substrate and covers the second reflective structure;

[0035] See also Figure 1 and Figure 2 A display panel 100 according to an embodiment of the present invention includes an array substrate 110 , a light emitting functional layer 120 and a second reflective structure 130 .

[0036] The array substrate 110 includes a first electrode 111 and a first reflective structure 112. In a direction parallel to the surface of the array substrate 110, the first reflective structure 112 is located at the periphery of the first electrode 111. The array substrate 110 also includes a pixel defining layer 113, and the pixel defining layer 113 includes a pixel opening.

[0037] The light emitting functional layer 120 is located on one side of the array substrate 110 . Furthermore, the light emitting functional layer 120 is located in a pixel opening of the pixel defining layer 113 .

[0038] The second reflective structure 130 is located on the side of the light-emitting functional layer 120 away from the array substrate 110. The second reflective structure 130 is used to reflect the light emitted by the light-emitting functional layer 120 back into the display panel 100, propagating to the non-opening area of ​​the pixel defining layer 113 and reaching the surface of the first reflective structure 112.

[0039] In each sub-pixel, the first reflective structure 112 , the light-emitting functional layer 120 and the second reflective structure 130 are arranged in a one-to-one correspondence.

[0040] The projection of the first reflective structure 112 on the surface of the array substrate 110 at least partially overlaps with the projection of the second reflective structure 130 on the surface of the array substrate 110. The first reflective structure 112 is used to reflect the light reflected by the second reflective structure 130 back to the inside of the display panel 100, and emit it from the non-luminous area between the luminous functional layers 120.

[0041] Specifically, Figure 1 As shown, Figure 1The middle arrow indicates the reflection path of the light. When the display panel 100 of this embodiment is used, part of the light emitted by the light-emitting functional layer 120 is directly emitted, and part of the light is reflected back to the interior of the display panel 100 through the second reflective structure 130, propagates to the non-opening area of ​​the pixel defining layer 113, and reaches the surface of the first reflective structure 112. After further reflection by the first reflective structure 112, it is emitted from the non-luminous area between the light-emitting functional layers 120. In this way, the proportion of the overall light-emitting area can be increased, and the screen window effect during display can be improved.

[0042] Further, in the display panel of the present invention, the array substrate 110 may include a substrate, a buffer layer, a gate insulating layer, an interlayer dielectric layer and a flat layer stacked in sequence. In a feasible implementation, the light-emitting functional layer 120 includes a first functional layer, a light-emitting layer and a second functional layer stacked in sequence on one side of the first electrode 111. Further, the display panel 100 also includes a second electrode. In a feasible implementation, the first electrode 111 is a cathode, the second electrode is an anode, the first functional layer is selected from at least one of an electron transport layer and an electron injection layer, and the second functional layer is selected from at least one of a hole transport layer and a hole injection layer. Further, the first functional layer includes an electron transport layer and an electron injection layer, and the second functional layer includes a hole transport layer and a hole injection layer. In another feasible implementation, the first electrode 111 is an anode, the second electrode is a cathode, the first functional layer is selected from at least one of a hole transport layer and a hole injection layer, and the second functional layer is selected from at least one of an electron transport layer and an electron injection layer. Furthermore, the present invention does not limit the materials and thicknesses of the functional layers of the array substrate 110 and the light-emitting functional layer 120 , and the materials and thicknesses may be commonly used in the art.

[0043] On the basis of the above-mentioned embodiment, the projection of the second reflective structure 130 on the surface of the array substrate 110 is located within the outer contour of the projection of the first reflective structure 112 on the surface of the array substrate 110. In this way, the first reflective structure 112 can reflect more light reflected back to the inside of the display panel 100 by the second reflective structure 130, and emit it from the non-luminescent area between the luminescent functional layers 120.

[0044] On the basis of the above-mentioned embodiment, the orthographic projection of the light-emitting functional layer 120 on the array substrate 110 does not overlap with the orthographic projection of the second reflective structure 130 on the array substrate 110. Preferably, there is a certain interval between the orthographic projection of the light-emitting functional layer 120 on the array substrate 110 and the orthographic projection of the second reflective structure 130 on the array substrate 110. In this way, the second reflective structure 130 can be prevented from blocking the light emitted by the light-emitting functional layer 120. It should be noted that the orthographic projection of the light-emitting functional layer 120 on the array substrate 110 and the orthographic projection of the second reflective structure 130 on the array substrate 110 can also be seamlessly connected.

[0045] On the basis of the above-mentioned embodiment, the first electrode 111 and the first reflective structure 112 are integrally formed. That is to say, the first electrode 111 and the first reflective structure 112 are integrally manufactured. Compared with the conventional display panel, in the display panel of the present invention, the area of ​​the first electrode 111 is relatively large, but the number of new masks is not added in the manufacturing process, the mask process is not additionally increased, and the process cost is not increased. Furthermore, the first electrode 111 is an anode. Of course, in other embodiments, the first electrode 111 can also be a reflective cathode.

[0046] On the basis of the above-mentioned embodiment, the reflectivity of the first reflective structure 112 is ≥ 80%, and the reflectivity of the second reflective structure 130 is 7% to 30%. Further, the reflectivity of the first reflective structure 112 may be, but not limited to, 80%, 85%, 90% or 95%, and the reflectivity of the second reflective structure 130 may be, but not limited to, 7%, 10%, 15%, 20%, 25% or 30%. At this time, the reflectivity of the first reflective structure 112 is relatively high, which is conducive to increasing the reflection intensity, and the second reflective structure 130 can not only play a reflective role, but also prevent the light from being completely blocked by the second reflective structure 130 to affect the display effect. In addition, in order to achieve a reflectivity of 7% to 30% for the second reflective structure 130, a material with a reflectivity within this range can be selected, or a high reflectivity material and a low reflectivity material can be combined, for example, an inorganic film layer such as silicon oxide or silicon nitride is stacked on the material of the first reflective structure 112.

[0047] Further, the material of the first reflective structure 112 is independently selected from at least one of a metal and a metal oxide. Further, the metal is selected from at least one of Ag, Cu, Al and Ti. Further, the metal oxide is selected from at least one of silver oxide, copper oxide, aluminum oxide and titanium dioxide. The second reflective structure 112 of these types of materials has a higher reflectivity, which is conducive to increasing the reflection intensity.

[0048] Furthermore, the material of the second reflective structure 130 includes molybdenum. Molybdenum has a certain reflectivity but not high, which can not only play a reflective role, but also prevent the light from being completely blocked by the second reflective structure 130 to affect the display effect.

[0049] On the basis of the foregoing embodiment, the thickness of the first reflective structure 112 is 30nm to 150nm, and the thickness of the second reflective structure 130 is 30nm to 150nm. Further, the thickness of the first reflective structure 112 includes but is not limited to 30nm, 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, 110nm, 120nm, 130nm, 140nm or 150nm, and the thickness of the second reflective structure 130 includes but is not limited to 30nm, 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, 110nm, 120nm, 130nm, 140nm or 150nm.

[0050] On the basis of the above-mentioned embodiment, the display panel 100 further includes an encapsulation layer 140, and the second reflective structure 130 is located on a side of the encapsulation layer 140 away from the array substrate 110. Further, the encapsulation layer 140 includes a first inorganic layer 141, an organic layer 142, and a second inorganic layer 143 which are sequentially stacked. Of course, the structure of the encapsulation layer 140 is not limited thereto, and may also be other layer structures capable of performing an encapsulation function.

[0051] On the basis of the above-mentioned embodiment, the display panel 100 further includes a protective layer 150, which is located on the side of the encapsulation layer 140 away from the array substrate 110 and covers the second reflective structure 130. The protective layer 150 can play a role in flattening and protecting the display panel 100. Furthermore, the emission range and angle of the emitted light can be adjusted by adjusting the refractive index of the pixel defining layer 113, the inorganic layer and the organic layer in the encapsulation layer 140, and the protective layer 150.

[0052] Further, the thickness of the protective layer 150 is 1 μm to 2 μm. The thickness of the protective layer 150 includes but is not limited to 1 μm, 1.1 μm, 1.2 μm, 1.3 μm, 1.4 μm, 1.5 μm, 1.6 μm, 1.7 μm, 1.8 μm, 1.9 μm or 2 μm.

[0053] On the basis of the above-mentioned embodiment, the reflectivity of the second reflective structure 130 is 7% to 30%. At this time, the reflectivity of the second reflective structure 130 is relatively high, which is beneficial to increase the reflection intensity.

[0054] Based on the above-mentioned embodiment, the second reflective structure 130 is made of metal. Preferably, the metal is Ag, Cu or Al. The second reflective structure 130 made of these materials has a higher reflectivity, which is beneficial to increase the reflection intensity.

[0055] Based on the above embodiment, the thickness of the second reflective structure 130 is 30 nm to 150 nm, including but not limited to 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, 110 nm, 120 nm, 130 nm, 140 nm or 150 nm.

[0056] On the basis of the above-mentioned embodiment, the display panel 100 further includes a protective layer 140, and the second reflective structure 130 is located between the protective layer 140 and the encapsulation layer 120. The protective layer 140 can play a role in flattening and protecting the display panel 100. Furthermore, the emission range and angle of the emitted light can be adjusted by adjusting the refractive index of the pixel defining layer 113, the inorganic layer and the organic layer in the encapsulation layer 120, and the protective layer 140.

[0057] Based on the above embodiment, the thickness of the protective layer 140 is 1 μm to 2 μm. The thickness of the protective layer 140 includes but is not limited to 1 μm, 1.1 μm, 1.2 μm, 1.3 μm, 1.4 μm, 1.5 μm, 1.6 μm, 1.7 μm, 1.8 μm, 1.9 μm or 2 μm.

[0058] It should be noted that the structure of the display panel of the present invention is not limited to the above-mentioned embodiment, and the second reflective structure may also be other structures.

[0059] See also Figure 3 and Figure 4 A display panel 200 according to another embodiment of the present invention includes an array substrate 210 , a light emitting functional layer 220 and a second reflective structure 230 .

[0060] The array substrate 210 includes a first electrode 211 and a first reflective structure 212. In a direction parallel to the surface of the array substrate 210, the first reflective structure 212 is located at the periphery of the first electrode 211. The array substrate 210 also includes a pixel defining layer 213, and the pixel defining layer 213 includes a pixel opening.

[0061] The light emitting function layer 220 is located on one side of the array substrate 210 . Furthermore, the light emitting function layer 220 is located in a pixel opening of the pixel defining layer 213 .

[0062] The second reflective structure 230 is located on the side of the light-emitting functional layer 220 away from the array substrate 210. The second reflective structure 230 is used to reflect the light emitted by the light-emitting functional layer 220 back into the display panel 200, propagating to the non-opening area of ​​the pixel defining layer 213 and reaching the surface of the first reflective structure 212.

[0063] In each sub-pixel, the first reflective structure 212 , the light-emitting functional layer 220 and the second reflective structure 230 are arranged in a one-to-one correspondence.

[0064] The projection of the first reflective structure 212 on the surface of the array substrate 210 at least partially overlaps with the projection of the second reflective structure 230 on the surface of the array substrate 210. The first reflective structure 212 is used to reflect the light reflected by the second reflective structure 230 back to the inside of the display panel 200, and emit it from the non-luminous area between the luminous functional layers 220.

[0065] Specifically, Figure 3 and Figure 4 The middle arrow indicates the reflection path of the light. When the display panel 200 of this embodiment is used, part of the light emitted by the light-emitting functional layer 212 is directly emitted from the encapsulation layer 220, and part of the light is reflected back to the interior of the display panel 200 through the second reflective structure 230, propagates to the non-opening area of ​​the pixel defining layer 213, and reaches the surface of the first reflective structure 214 where the light-emitting functional layer 212 is not set. After further reflection by the first reflective structure 214, the light is emitted from the non-light-emitting area between the light-emitting functional layers 212. In this way, the proportion of the overall light-emitting area can be increased, and the screen window effect during display can be improved.

[0066] Further, in the display panel of the present invention, the array substrate 210 may include a substrate, a buffer layer, a gate insulating layer, an interlayer dielectric layer and a flat layer stacked in sequence. In a feasible implementation, the light-emitting functional layer 220 includes a first functional layer, a light-emitting layer and a second functional layer stacked in sequence on one side of the first electrode 211. Further, the display panel 200 also includes a second electrode. In a feasible implementation, the first electrode 211 is a cathode, the second electrode is an anode, the first functional layer is selected from at least one of an electron transport layer and an electron injection layer, and the second functional layer is selected from at least one of a hole transport layer and a hole injection layer. Further, the first functional layer includes an electron transport layer and an electron injection layer, and the second functional layer includes a hole transport layer and a hole injection layer. In another feasible implementation, the first electrode 211 is an anode, the second electrode is a cathode, the first functional layer is selected from at least one of a hole transport layer and a hole injection layer, and the second functional layer is selected from at least one of an electron transport layer and an electron injection layer. Furthermore, the present invention does not limit the materials and thicknesses of the functional layers of the array substrate 210 and the light-emitting functional layer 220 , and the materials and thicknesses may be commonly used in the art.

[0067] Furthermore, in the display panel 200 of the present embodiment, the second reflective structure 230 includes a plurality of concentrically arranged reflective rings 231. In the display panel 200 of the present embodiment, since the second reflective structure 230 includes a plurality of concentrically arranged reflective rings 231, part of the light reaching the reflective structure 230 is reflected back into the display panel 200, and part of the light is emitted through the gap between adjacent reflective rings 231, or is reflected from the side of the reflective structure 230 and then emitted, thereby making the light originally emitted from the light-emitting functional layer 220 and the light emitted after being reflected from the reflective structure 230 more continuous, and the continuity after the light-emitting area is enlarged.

[0068] It should be noted that the present invention does not limit the number of reflection rings 231 , the size of the reflection rings 231 , and the interval between two adjacent reflection rings 231 among the concentrically arranged reflection rings 231 , and they can be set according to actual needs.

[0069] In this embodiment, the first electrode 211 and the first reflective structure 212 are integrally formed. Furthermore, the first electrode 211 is an anode. Compared with the traditional display panel, in the display panel of the present invention, the area of ​​the first electrode 211 is relatively large, but the number of new masks is not added in the manufacturing process, and the mask process is not additionally increased, and the process cost is not increased.

[0070] Based on the above embodiment, the display panel 200 further includes an encapsulation layer 240, and the second reflective structure 230 is located on a side of the encapsulation layer 240 away from the array substrate 210. Further, the encapsulation layer 240 includes a first inorganic layer 241, an organic layer 242, and a second inorganic layer 243 stacked in sequence.

[0071] On the basis of the above-mentioned embodiment, the display panel 200 further includes a protective layer 250, which is located on the side of the encapsulation layer 240 away from the array substrate 210 and covers the second reflective structure 230. The protective layer 250 can play a role in flattening and protecting the display panel 200. Furthermore, the emission range and angle of the emitted light can be adjusted by adjusting the refractive index of the pixel defining layer 213, the inorganic layer and the organic layer in the encapsulation layer 240, and the protective layer 250.

[0072] In addition, it should be noted that the reflectivity, material, thickness of the second reflective structure 230 of this embodiment and the thickness of the protective layer 250 can all be selected as in the above-mentioned embodiments.

[0073] In the display panel using the technical solution of the present invention, part of the light emitted by the light-emitting functional layer is directly emitted, and part of the light is reflected back into the display panel through the second reflective structure, propagates to the non-opening area of ​​the pixel defining layer, and reaches the surface of the first reflective structure. After further reflection by the first reflective structure, it is emitted from the non-light-emitting area between the light-emitting functional layers. In this way, the proportion of the overall light-emitting area can be increased, thereby improving the screen window effect during display.

[0074] The display panel of the present invention can be used in RGB-OLED processes, such as RGB-AMOLED, which increases the possibility for RGB-OLED to enter the VR market. The display panel using the technical solution of the present invention can alleviate the process pressure that the gap between the pixel-defining layer cannot be compressed to the limit, and give play to the optical and electrical advantages of RGB-OLED. In the display panel of the present invention, the second reflective structure and the protective layer above the second reflective structure can be easily combined with the existing Array process, and the process adaptability is high. There is no need to carry out processes such as lenses in the background technology, and the process flow is simple. Furthermore, it can be integrated into the existing Metal Mesh TP technology without adding a Mask process or increasing process costs.

[0075] A VR device according to one embodiment includes any one of the above-mentioned display panels.

[0076] The VR device of the technical solution of the present invention includes the above-mentioned display panel. Part of the light emitted by the light-emitting functional layer is directly emitted, and part of the light is reflected back to the interior of the display panel through the second reflective structure, propagates to the non-opening area of ​​the pixel defining layer, and reaches the surface on the first reflective structure. After further reflection by the first reflective structure, it is emitted from the non-luminous area between the light-emitting functional layers. In this way, the proportion of the overall light-emitting area can be increased and the screen window effect during display can be improved.

[0077] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
