[0065] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0066] See also Figure 1The display panel in the related art includes a display area AA and a non-display area AB, and the display panel includes an array substrate 1, a plurality of sub-pixels 2 located on one side of the array substrate 1, and the colors of the plurality of sub-pixels 2 may be different, a first lens layer 3 located on the side of the sub-pixel 2 away from the array substrate 1, and a second lens layer 4 located on the side of the first lens layer 3 away from the array substrate 1. Among them, a plurality of area holes are provided on the first lens layer 3, and the orthographic projection of the area holes on the array substrate 1 is located within the orthographic projection of the sub-pixel 2 on the array substrate 1. The material of the first lens layer 3 is a material with a low refractive index, and the second lens layer 4 is a material with a high refractive index. The second lens layer 4 located at the area hole constitutes a lens structure, and the lens structure can improve the light extraction efficiency of the sub-pixel 2. However, in the related art, when the second lens layer 4 is set, the material of the second lens layer 4 may overflow to the non-display area, and finally overflow to the edge position of the display panel frame. In this way, the cover plate of the display panel may not be flush, and the display panel may have bubbles, black spots, carbonization and other undesirable phenomena, which ultimately affect the display quality of the display panel.

[0067] In view of this, the present embodiment provides a solution for improving the light extraction efficiency of the display panel without affecting the display quality of the display panel. The solution provided by the present embodiment is described in detail below.

[0068] See also Figure 2 This embodiment provides a display panel, which includes a display area AA and a non-display area AB; the display panel includes an array substrate 1, a barrier layer 5 and a lens layer 6.

[0069] The array substrate 1 may include a substrate and a plurality of driving units located on one side of the substrate, and each driving unit may include one or more semiconductor switching devices. The semiconductor switching device may be formed by the cooperation of a plurality of film layers in the array substrate 1, for example, the semiconductor switching device may be a thin film transistor formed by the cooperation of a plurality of film layers.

[0070] The barrier layer 5 is located on one side of the array substrate 1 ; the barrier layer 5 includes an isolation structure 51 and a blocking structure 52 arranged in the same layer, the isolation structure 51 is located in the display area AA, and the blocking structure 52 is located in the non-display area AB.

[0071] Optionally, see Figure 3 , the isolation structure 51 includes a conductive material; the isolation structure 51 encloses an isolation opening 511; the display panel also includes a light-emitting unit and a pixel defining layer 7, the light-emitting unit is located in the isolation opening 511, and the light-emitting unit includes a first electrode layer 8, a light-emitting layer 9 and a second electrode layer 10.

[0072] The first electrode 8 layer is located on one side of the array substrate 1, and the first electrode 8 layer includes a plurality of first electrodes 8 arranged at intervals. The first electrode 8 is an anode, the second electrode layer 10 is a cathode layer, one first electrode 8, one light-emitting layer 9 and the second electrode layer 10 constitute a light-emitting unit, and the array substrate 1 applies voltage to the first electrode 8 and the second electrode layer 10 to drive the light-emitting unit to emit light.

[0073] The pixel defining layer 7 is located on the side of the first electrode 8 layer away from the array substrate 1, and the pixel defining layer 7 includes a pixel opening exposing at least a portion of the first electrode 8; the orthographic projection of the isolation structure 51 on the array substrate 1 is located between the orthographic projections of two adjacent pixel openings on the array substrate 1.

[0074] The light-emitting layer 9 and the second electrode layer 10 are located in the pixel opening and are stacked in sequence in a direction away from the array substrate 1; at least part of the second electrode layer 10 extends from the pixel opening to the side of the pixel defining layer 7 away from the array substrate 1 and is in electrical contact with the conductive material of the isolation structure 51.

[0075] When forming the light-emitting layer 9 and the second electrode layer 10, the isolation structure 51 can disconnect the light-emitting layer 9 and the second electrode layer 10 of the adjacent light-emitting units, and make at least part of the second electrode layer 10 extend from the pixel opening to the side of the pixel defining layer 7 away from the array substrate 1 to be in electrical contact with the isolation structure 51. The isolation structure 51 can connect the adjacent second electrode layer 10 or connect the second electrode layer 10 to other circuits. In this way, the patterning design of the light-emitting layer 9 and the second electrode layer 10 can be realized without using a precision mask, thereby reducing the manufacturing difficulty of the display panel.

[0076] The orthographic projection of the isolation structure 51 on the array substrate 1 surrounds the orthographic projection of the pixel opening on the array substrate 1 .

[0077] The lens layer 6 is located on a side of the barrier layer 5 away from the array substrate 1 ; at least a portion of the lens layer 6 is located in the display area AA.

[0078] See also Figure 4 The lens layer 6 includes a first refractive layer 61 located on the side of the isolation layer away from the array substrate 1 and a second refractive layer 62 located on the side of the first refractive layer 61 away from the array substrate 1. The first refractive layer 61 is provided with a plurality of zone holes, and the orthographic projection of the zone holes on the array substrate 1 is located within the orthographic projection of the light-emitting unit on the array substrate 1. The material of the first refractive layer 61 is a material with a low refractive index, and the second refractive layer 62 is a material with a high refractive index. The second refractive layer 62 located at the zone holes constitutes a lens structure, and the lens structure can improve the light extraction efficiency of the sub-pixel.

[0079] Please see again Figure 3 or Figure 4There is a certain gap 13 between the blocking structure 52 and the lens layer 6. When the lens layer 6 is formed, the material of the lens layer 6 will overflow to the gap 13 between the blocking structure 52 and the lens layer 6 under its own flow. The blocking structure 52 can block the material of the lens layer 6, so that the material of the lens layer 6 is not easy to overflow to the edge of the frame of the display panel, so that the cover plate of the display panel can be more flush, and the display panel is not easy to produce bubbles, black spots, carbonization and other undesirable phenomena due to the overflow of the material of the lens layer 6 to the edge of the frame. Therefore, while setting the lens structure to improve the light output efficiency of the display panel, the display quality of the display panel can be improved.

[0080] Based on the above design, this embodiment sets an isolation structure 51 in the display area and a blocking structure 52 in the non-display area. The blocking structure 52 can block the material of the lens layer 6, so that the material of the lens layer 6 is not easy to overflow to the edge of the display panel, thereby improving the display quality of the display panel.

[0081] In one possible implementation, see again Figure 3 The isolation structure 51 includes a first isolation portion 11 and a second isolation portion 12 which are stacked in sequence in a direction away from the array substrate 1 , and the orthographic projection of the first isolation portion 11 on the array substrate 1 is located within the orthographic projection of the second isolation portion 12 on the array substrate 1 .

[0082] Since the second isolation portion 12 is located on the side of the first isolation portion 11 away from the array substrate 1, and the lateral width of the second isolation portion 12 is greater than the lateral width of the first isolation portion 11, the second isolation portion 12 disconnects the light emitting layer 9 and the second electrode layer 10 at the isolation structure 51. In the display area AA, the first isolation portion 11 and the second isolation portion 12 form an isolation structure 51, which can make each pixel independent.

[0083] In one possible implementation, see again Figure 3 , the first isolation portion 11 includes a conductive material, and the second electrode layer 10 is electrically connected to the first isolation portion 11; see Figure 5 , or the isolation structure 51 also includes a third isolation portion 14 located on the side of the first isolation portion 11 facing the array substrate 1, the third isolation portion 14 includes a conductive material, and the second electrode layer 10 is electrically connected to the third isolation portion 14; the material of the third isolation portion 14 includes molybdenum metal; and / or the material of the first isolation portion 11 includes aluminum metal; and / or the material of the second isolation portion 12 includes a titanium metal layer.

[0084] At least a portion of the second electrode layer 10 extends from the pixel opening to the side of the pixel defining layer 7 away from the array substrate 1 and is in electrical contact with the third isolation portion 14 or the first isolation portion 11 in the isolation structure 51. The third isolation portion 14 or the first isolation portion 11 of the isolation structure 51 can connect adjacent second electrode layers 10, or connect the second electrode layer 10 to other circuits, thereby making it easier for the isolation structure 51 to isolate the second electrode layer 10 and electrically connect the second electrode layer 10.

[0085] Preferably, see again Figure 3 The blocking structure 52 includes a first isolation portion 11 and a second isolation portion 12 which are sequentially stacked in a direction away from the array substrate 1; please refer to Figure 5 , or the blocking structure 52 further includes a third isolation portion 14 located on a side of the first isolation portion 11 facing the array substrate 1 .

[0086] The blocking structure 52 has the same structure and material as the isolation structure 51. While the isolation structure 51 is formed in the display area AA, the blocking structure 52 is formed in the non-display area AB. The isolation structure 51 and the blocking structure 52 can be formed simultaneously through the same process. Therefore, high-end application of new technologies can be achieved without increasing the difficulty of the process.

[0087] In one possible implementation, see Figure 5-Figure 6 The non-display area at least partially surrounds the display area, the number of the blocking structure 52 is one, and one blocking structure 52 at least partially surrounds the display area AA.

[0088] The blocking structure 52 is located at the frame position of the display panel. The blocking structure 52 is a structure that surrounds the display area AA in a whole layer. The blocking structure 52 is also separated from the display area AA by a certain gap 13. When the lens material of the lens layer 6 located in the display area AA overflows to the non-display area AB, the blocking structure 52 can block the lens material of the lens layer 6 into the gap 13 between the blocking structure 52 and the lens layer 6, so that the material of the lens layer 6 is not easy to overflow to the edge of the frame of the display panel. In this way, the lens structure is set on the display panel to improve the light extraction efficiency of the display panel and improve the display quality of the display panel.

[0089] Preferably, see again Figure 5 , part of the lens layer 6 is located in the non-display area AB, and the distance L1 from the orthographic projection of the side of the lens layer 6 on the array substrate 1 to the display area AA is smaller than the distance L2 from the orthographic projection of the side of the blocking structure 52 away from the display area AA on the array substrate 1 to the display area AA.

[0090] The lens layer 6 includes a side close to the array substrate 1, a side away from the array substrate 1, and a side edge, and the blocking structure 52 includes a side close to the array substrate 1, a side away from the array substrate 1, and a side edge. When the lens layer 6 is formed, part of the lens layer 6 material will overflow to the non-display area AB, and the blocking structure 52 located in the non-display area AB will block the lens layer 6 material overflowing to the non-display area AB, so that the lens layer 6 material overflowing to the non-display area AB cannot turn over the blocking structure 52 to reach the edge of the frame of the display panel.

[0091] Preferably, see again Figure 5 , the side of the lens layer 6 overlaps with the side of the blocking structure 52 close to the display area AA. The lens layer 6 material overflowing to the non-display area AB is blocked by the side of the blocking structure 52 close to the display area AA, so that the lens layer 6 material overflowing to the non-display area AB cannot overflow to the side of the blocking structure 52 away from the array substrate 1, so that the lens layer 6 material is less likely to overflow to the edge of the frame of the display panel.

[0092] In one possible implementation, see Figure 7-Figure 8 The non-display area AB at least partially surrounds the display area AA, there are multiple blocking structures 52, each of the multiple blocking structures 52 at least partially surrounds the display area AA, and the multiple blocking structures 52 are arranged in a direction from the non-display area AB to the display area AA.

[0093] Multiple blocking structures 52 are all located at the frame position of the display panel and surround the display area AA in sequence. The blocking structure 52 is still separated from the lens layer 6 by a certain gap 13, and there is also a certain gap 13 between the multiple blocking structures 52. When the lens material of the lens layer 6 located in the display area AA overflows to the non-display area AB, the blocking structure 52 can block the lens material of the lens layer 6 into the gap 13 between the blocking structure 52 and the lens layer 6. After the lens material fills the gap 13 between the blocking structure 52 and the lens layer 6, the lens material can turn over the blocking structure 52 closest to the display area AA, and then overflow to the gap 13 between the adjacent blocking structures 52. In this way, the material of the lens layer 6 is not easy to overflow to the edge of the frame of the display panel. In this way, the lens structure is set on the display panel to improve the light extraction efficiency of the display panel while improving the display quality of the display panel.

[0094] Preferably, see again Figure 7 , part of the lens layer 6 is located in the non-display area AB, and the distance L3 from the orthographic projection of the side of the lens layer 6 on the array substrate 1 to the display area AA is smaller than the distance L4 from the orthographic projection of the side of the blocking structure 52 farthest from the display area AA away from the display area AA on the array substrate 1 to the display area AA.

[0095] When there are multiple blocking structures 52 in the non-display area AB, the material of the lens layer 6 overflowing to the non-display area AB may overflow over some of the blocking structures 52 close to the display area AA, but the material of the lens layer 6 will not overflow over the blocking structure 52 farthest from the display area AA, so that the material of the lens layer 6 is not easy to overflow to the edge of the frame of the display panel.

[0096] Preferably, see again Figure 7 , the side of the lens layer 6 overlaps with the side of the blocking structure 52 close to the display area AA. When there are multiple blocking structures 52 in the non-display area AB, the material of the lens layer 6 overflowing to the non-display area AB is blocked by the side of any blocking structure 52 close to the display area AA. In this way, the material of the lens layer 6 overflowing to the non-display area AB will not overflow to the side of the blocking structure 52 farthest from the display area AA and away from the array substrate 1, so that the material of the lens layer 6 is less likely to overflow to the edge of the frame of the display panel.

[0097] In one possible implementation, see Fig. 9 The display panel also includes a touch line 15 located on the side of the blocking structure 52 away from the array substrate 1. The touch line 15 extends from the non-display area to the display area. The touch line 15 is electrically connected to the blocking structure 52. The touch line 15 is located between the blocking structure 52 and the lens layer 6. The lens layer 6 covers the touch line 15.

[0098] The touch line 15 is arranged on a side of the blocking structure 52 away from the array substrate 1 . The blocking structure 52 can support the touch line 15 , thereby reducing the breakage of the touch line 15 , and thus the touch line 15 is not easily broken and causes a circuit breaker.

[0099] The touch line 15 at the frame position is electrically connected to the blocking structure 52 , so that the square resistance of the touch line 15 can be reduced, thereby reducing the load of the touch line 15 and further reducing the power consumption of the display panel.

[0100] Preferably, the orthographic projection of the touch line 15 on the array substrate 1 is within the orthographic projection of the blocking structure 52 on the array substrate 1. In this way, the support effect of the blocking structure 52 on the touch line 15 can be improved, thereby further preventing the touch line 15 from being easily broken and causing a circuit breaker.

[0101] In a possible implementation manner, an anti-overflow groove 16 recessed toward the array substrate 1 is further provided on a side of the blocking structure 52 away from the array substrate 1 .

[0102] See also Fig.10When the number of the blocking structure 52 is one, after the lens material fills the gap 13 between the blocking structure 52 and the lens layer 6, the lens material can also overflow into the anti-overflow groove 16 on the side of the blocking structure 52 away from the array substrate 1. In this way, the lens material is more likely to overflow to the edge of the frame of the display panel.

[0103] See also Fig.11 When there are multiple blocking structures 52, after the lens material fills the gap 13 between the blocking structure 52 and the lens layer 6, the lens material can also overflow into the anti-overflow groove 16 on the side of the blocking structure 52 away from the array substrate 1 and can overflow into the gap 13 between adjacent isolation structures 51. In this way, the lens material is more likely to overflow to the edge of the frame of the display panel.

[0104] Preferably, see again Figure 10-11 The number of the anti-overflow grooves 16 is multiple, and the multiple anti-overflow grooves 16 are arranged along the direction from the display area to the non-display area.

[0105] When the depth and width of the overflow prevention groove 16 are the same, the more the number of overflow prevention grooves 16 is, the more the amount of lens material blocked is. Therefore, by providing a plurality of overflow prevention grooves 16, more lens material can be blocked, so that the lens material can overflow to the edge of the frame of the display panel more easily.

[0106] Preferably, the anti-overflow groove 16 at least partially surrounds the display area AA. The anti-overflow groove 16 has the same direction as the blocking structure 52, and the anti-overflow groove 16 surrounds the lens layer 6, so that the lens material can overflow into the anti-overflow groove 16 from different directions, so that the lens material can overflow to different edge positions of the frame of the display panel more easily.

[0107] In one possible implementation, see Fig.12 The display panel further includes an encapsulation layer 17 located between the barrier layer 5 and the lens layer 6. The encapsulation layer 17 can protect the light-emitting unit, thereby increasing the life of the light-emitting unit.

[0108] Preferably, see again Fig.12 The display panel further includes a dam structure 18 located in the non-display area AB, and the dam structure 18 is located on the side of the blocking structure 52 close to the display area AA; the distance D1 from the side of the dam structure 18 away from the array substrate 1 to the array substrate 1 is greater than the distance D2 from the side of the encapsulation layer 17 away from the array substrate 1 to the array substrate 1. In this way, the dam structure 18 can block the material of the encapsulation layer 17, so that the material of the encapsulation layer 17 is not easy to flow to the non-display area AB.

[0109] Preferably, see again Fig.12, the distance D1 between the side of the dam structure 18 away from the array substrate 1 and the array substrate 1 is greater than the distance D3 between the side of the blocking structure 52 away from the array substrate 1 and the array substrate 1. The dam structure 18 is closer to the lens layer 6 than the blocking structure 52. When the lens layer 6 is provided, the material of the lens layer 6 turns over the dam and combines with the non-display area AB, and then the blocking structure 52 blocks the material of the lens layer 6 from overflowing to the edge of the display panel.

[0110] Preferably, see again Fig.12 The difference between the distance D1 from the side of the dam structure 18 away from the array substrate 1 to the array substrate 1 and the distance D3 from the side of the blocking structure 52 away from the array substrate 1 to the array substrate 1 is in the range of 0.01 μm-0.05 μm. For example, the difference between the distance D1 and the distance D2 can be 0.01 μm, 0.02 μm, 0.03 μm, 0.04 μm or 0.05 μm. When the height of the blocking structure 52 is constant, if the difference between the distance D1 and the distance D2 is set too small, the blocking effect of the dam structure 18 on the material of the encapsulation layer 17 will be affected. If the difference between the distance D1 and the distance D2 is set too large, the thickness of the display panel will be increased. Therefore, the difference between the distance D1 and the distance D2 is reasonably set, which will neither affect the blocking effect of the dam structure 18 on the material of the encapsulation layer 17 nor increase the thickness of the display panel.

[0111] Preferably, see again Fig.12 , along the direction away from the array substrate 1, the encapsulation layer 17 includes a first inorganic encapsulation layer 171, an organic encapsulation layer 172, and a second inorganic encapsulation layer 173 stacked in sequence; the first inorganic encapsulation layer 171 includes a plurality of spaced encapsulation units 1711, the encapsulation units 1711 are located on the side of the light-emitting unit away from the array substrate 1, and extend to the side wall of the isolation structure 51 and contact the isolation structure 51, and at least part of the encapsulation units 1711 also extend from the side wall of the isolation structure 51 to the side of the isolation structure 51 away from the array substrate. The encapsulation units 1711 encapsulate the plurality of light-emitting units separately and independently, thereby improving the reliability of the encapsulation and optimizing the optical performance of the display panel.

[0112] Preferably, see again Fig.12 The display panel further includes a cover plate 19 located on a side of the lens layer 6 away from the array substrate 1 , and the cover plate 19 can protect the lens layer 6 and the like.

[0113] In summary, the present application sets an isolation structure 51 in the display area and a blocking structure 52 in the non-display area. The blocking structure 52 can block the material of the lens layer 6, so that the material of the lens layer 6 is not easy to overflow to the edge of the display panel, thereby improving the display quality of the display panel.

[0114] In one possible implementation, see Fig.13 The present application also provides a method for preparing a display panel, wherein the display panel includes a display area AA and a non-display area AB; the method includes:

[0115] S10: providing an array substrate 1.

[0116] The array substrate 1 may include a plurality of drive units, each of which may include one or more semiconductor switch devices. The semiconductor switch device may be formed by the cooperation of a plurality of film layers in the array substrate 1, for example, the semiconductor switch device may be a thin film transistor formed by the cooperation of a plurality of film layers.

[0117] S11: forming a barrier layer 5 on one side of the array substrate 1; the barrier layer 5 comprises an isolation structure 51 and a blocking structure 52 arranged in the same layer, the isolation structure 51 is located in the display area AA, and the blocking structure 52 is located in the non-display area AB.

[0118] The barrier layer 5 surrounds the sub-pixels of the display panel, the barrier structure 52 surrounds the display area AA of the display panel, and there is a certain gap 13 between the barrier structure 52 and the lens layer 6 .

[0119] S12: forming a lens layer 6 on a side of the barrier layer 5 away from the array substrate 1; the lens layer 6 is at least partially located in the display area AA.

[0120] When the lens layer 6 is formed, the material of the lens layer 6 will overflow to the gap 13 between the blocking structure 52 and the lens layer 6 under its own flow. The blocking structure 52 can block the material of the lens layer 6, so that the material of the lens layer 6 is not easy to overflow to the edge of the frame of the display panel, so that the cover plate of the display panel can be more flush, and the display panel is not easy to produce bubbles, black spots, carbonization and other undesirable phenomena due to the overflow of the lens layer 6 to the edge of the frame. Therefore, while setting the lens structure to improve the light output efficiency of the display panel, the display quality of the display panel can be improved.

[0121] Preferably, see Fig.14 , before the step of forming the barrier layer 5 on one side of the array substrate 1, the method further includes:

[0122] S01: forming a first electrode 8 layer on one side of the array substrate 1 , wherein the first electrode 8 layer includes a plurality of first electrodes 8 arranged at intervals.

[0123] S02 : forming a pixel defining layer 7 on a side of the first electrode 8 layer away from the array substrate 1 , wherein the pixel defining layer 7 includes a pixel opening exposing at least a portion of the first electrode 8 .

[0124] Before the step of forming the lens layer 6 on the side of the barrier layer 5 away from the array substrate 1, the method further includes:

[0125] S03: A light-emitting layer 9 and a second electrode layer 10 are sequentially formed in a stacked manner in the pixel opening along a direction away from the array substrate 1; at least a portion of the second electrode layer 10 extends from the pixel opening to a side of the pixel defining layer 7 away from the array substrate 1 and is in electrical contact with the conductive material of the isolation structure 51.

[0126] See also Fig.15 , a plurality of first electrodes 8 are formed at intervals on one side of the array substrate 1, and then a pixel defining layer 7 is formed on one side of the array substrate 1, and the pixel opening of the pixel defining layer 7 at least partially exposes the first electrode 8. A first electrode 8, a light-emitting layer 9 and a second electrode layer 10 constitute a light-emitting unit, and the array substrate 1 applies voltage to the first electrode 8 and the second electrode layer 10 to drive the light-emitting unit to emit light.

[0127] See also Fig.16 , while forming the isolation structure 51 in the display area AA, forming the blocking structure 52 in the non-display area AB. In this way, the process can be simplified and the cost of manufacturing the display panel can be saved.

[0128] See also Fig.17 , the light-emitting layer 9 and the second electrode layer 10 are sequentially formed in the pixel opening. When the light-emitting layer 9 and the second electrode layer 10 are formed, the isolation structure 51 can disconnect the light-emitting layer 9 and the second electrode layer 10 of the adjacent light-emitting units, and make at least part of the second electrode layer 10 extend from the pixel opening to the side of the pixel defining layer 7 away from the array substrate 1 to be in electrical contact with the isolation structure 51. The isolation structure 51 can connect the adjacent second electrode layer 10 or connect the second electrode layer 10 to other circuits. In this way, the patterning design of the light-emitting layer 9 and the second electrode layer 10 can be realized without using a precision mask, thereby reducing the manufacturing difficulty of the display panel.

[0129] The orthographic projection of the isolation structure 51 on the array substrate 1 surrounds the orthographic projection of the pixel opening on the array substrate 1, and the second electrode layer 10 also includes an encapsulation layer on the side away from the array substrate 1. The encapsulation layer independently encapsulates multiple light-emitting units so that the light-emitting units are independent of each other, thereby improving the reliability of the encapsulation and optimizing the optical performance of the display panel.

[0130] In a possible implementation, the present application further provides an electronic device, the electronic device including the display panel in the present application. The electronic device may include a device with image processing capabilities, such as a server, a personal computer, a laptop computer, etc. The electronic device may include a device with image processing capabilities, such as a server, a personal computer, a laptop computer, etc. Since the electronic device includes the display panel described in the present application, the electronic device can improve the display quality while improving the light extraction efficiency.
