[0042] In recent years, OLED (Organic Light-Emitting Diode) has attracted widespread attention due to its huge application market in the display field. Compared with other display technologies, OLED modules have many advantages, such as wide viewing angle, fast response speed, no need for backlighting, and flexible display.

[0043] How to optimize the structure of the display panel in the related art to reduce the manufacturing cost is an issue worth considering.

[0044] In view of the above problems, an embodiment of the first aspect of the present application proposes a display panel, aiming to reduce the manufacturing cost of the display panel.

[0045] like Figure 1 , Figure 2As shown, the display panel 100 in the embodiment of the first aspect of the present application includes an opening area 101, a display area 102 at least partially surrounding the opening area 101, and a non-display area 103 between the opening area 101 and the display area 102. The display panel 100 includes a substrate 110, a light-emitting functional layer 130, a partition structure 140, and an isolation column 300. The light-emitting functional layer 130 is disposed on one side of the substrate 110 and is located in the display area 102. The light-emitting functional layer 130 includes a plurality of light-emitting functional parts 131 disposed at intervals. The partition structure 140 is disposed in the display area 102, and the partition structure 140 isolates adjacent light-emitting functional parts 131. The isolation column 300 is disposed in the non-display area 103 and is disposed around the opening area 101, wherein the isolation column 300 and the partition structure 140 are disposed in the same layer and made of the same material.

[0046] Specifically, the display panel 100 may be an OLED display panel, wherein the substrate 110 may include a substrate and a driving circuit layer disposed on the substrate. The substrate may be a rigid substrate or a flexible substrate. When the substrate is a rigid substrate, the material of the substrate may be glass or silicon wafer, etc. When the substrate is a flexible substrate, the material of the substrate may be metal foil, polymer plastic, etc.

[0047] The display area 102 of the display panel 100 is used to display images, and the opening area 101 is used to place functional devices such as camera modules. The isolation column 300 arranged around the opening area 101 is used to isolate the light-emitting functional layer 130 located in the display area 102 from the opening area 101 to prevent external water vapor and oxygen from passing through the isolation column 300 and entering the display area 102, that is, the isolation column 300 is used to prevent water vapor and oxygen in the opening area 101 from entering the display area 102 and causing display failure.

[0048] The light-emitting functional layer 130 includes a plurality of light-emitting functional parts 131 arranged at intervals. The light-emitting functional parts 131 specifically include an organic light-emitting layer, and may also include organic auxiliary film layers such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer.

[0049] The partition structure 140 is used to partition the light-emitting functional layer 130 to form light-emitting functional parts 131 that are spaced apart from each other.

[0050] The display panel 100 in the embodiment of the present application is provided with a partition structure 140 in the display area 102, and the partition structure 140 is used to partition the adjacent light-emitting functional parts 131, and an isolation column 300 is provided in the non-display area 103 between the display area 102 and the opening area 101, and the isolation column 300 is used to prevent water vapor and oxygen in the opening area 101 from entering the display area 102. Among them, the isolation column 300 and the partition structure 140 are arranged in the same layer and made of the same material, so that the isolation column 300 and the partition structure 140 can be manufactured in the same manufacturing process, and the manufacturing of the isolation column 300 and the manufacturing of the partition structure 140 can share a mask plate. In this way, it is beneficial to reduce the manufacturing cost of the display panel 100 and also to improve the production efficiency.

[0051] In some embodiments, Figures 2 to 4 As shown, the partition structure 140 includes a first insulator 141 and a first blocking portion 142, wherein the first blocking portion 142 is located on the side of the first insulator 141 away from the substrate 110, and the orthographic projection of the top surface of the first insulator 141 on the substrate 110 is located within the orthographic projection of the bottom surface of the first blocking portion 142 on the substrate 110. The first insulator 141 is mainly used to isolate the light-emitting functional portion 131 in the light-emitting functional layer 130. The first blocking portion 142 is located on the side of the first insulator 141 away from the substrate 110, and the orthographic projection of the top surface of the first insulator 141 on the substrate 110 is located within the orthographic projection of the bottom surface of the first blocking portion 142 on the substrate 110, that is, there is a certain distance between the edge of the bottom surface of the first blocking portion 142 and the edge of the top surface of the first insulator 141, so that the portion of the first blocking portion 142 that exceeds the edge of the first insulator 141 forms a step structure. The setting of the step structure is beneficial to isolating the light-emitting material layers formed on different sides of the partition structure 140 from each other during the evaporation process.

[0052] Furthermore, the isolation column 300 may include a second isolation body 310 and a second blocking portion 320, wherein the second blocking portion 320 is disposed on a side of the second isolation body 310 away from the substrate 110, and the orthographic projection of the top surface of the second isolation body 310 on the substrate 110 is located within the orthographic projection of the second blocking portion 320 on the substrate 110. The first isolation body 141 and the second isolation body 310 are disposed on the same layer and made of the same material, and the second blocking portion 320 and the first blocking portion 142 are disposed on the same layer and made of the same material. The isolation column 300 functions to separate the light-emitting functional layer 130 located in the display area 102 from the opening area 101. The second blocking portion 320 is arranged on the side of the second insulator 310 facing away from the substrate 110, and the orthographic projection of the top surface of the second insulator 310 on the substrate 110 is located within the orthographic projection of the second blocking portion 320 on the substrate 110, so that there is a certain distance between the bottom surface edge of the second blocking portion 320 and the top surface edge of the second insulator 310, so that the part of the second blocking portion 320 that exceeds the edge of the second insulator 310 forms a step structure. The setting of the step structure is conducive to better isolating the light-emitting functional layer 130 to improve the effect of blocking water vapor and oxygen.

[0053] On the other hand, the manufacturing process of the partition structure 140 is generally as follows: first, a first material layer for making the first insulator 141 is deposited, and then a second material layer for making the first blocking portion 142 is deposited on the first material layer. Then, the first material layer and the second material layer are patterned using a photolithography process, thereby manufacturing the first insulator 141 and the first blocking portion 142. In this embodiment, the first insulator 141 and the second insulator 310 are arranged in the same layer and made of the same material, and the second blocking portion 320 and the first blocking portion 142 are arranged in the same layer and made of the same material. In this way, the first material layer can also be used to make the second insulator 310, and the second material layer can also be used to make the second blocking portion 320, so that after the first material layer and the second material layer are patterned, the second insulator 310 and the second blocking portion 320 can also be manufactured. This is conducive to simplifying the manufacturing process of the display panel and reducing the manufacturing cost.

[0054] In some embodiments, the material of the second insulator 310 is a first metal, and the material of the second barrier 320 is a second metal, wherein the etching efficiency of the first metal is greater than the etching efficiency of the second metal.

[0055] In the process of patterning the first material layer and the second material layer, an etching solution is used to etch the first material layer and the second material layer, so as to produce the first isolator 141 and the second isolator 310, as well as the first blocking portion 142 and the second blocking portion 320. In this embodiment, the second isolator 310 and the second blocking portion 320 are made of different materials, that is, the material of the second isolator 310 is the first metal, and the material of the second blocking portion 320 is the second metal, and the etching efficiency of the first metal is greater than the etching efficiency of the second metal. In this way, within the same etching time, the etching amount of the first metal is greater than the etching amount of the second metal, thereby making the produced second isolator 310 form a certain amount of indentation relative to the second blocking portion 320, so that the orthographic projection of the top surface of the second isolator 310 on the substrate 110 is located within the orthographic projection of the second blocking portion 320 on the substrate 110.

[0056] Similarly, because the first insulator 141 and the second insulator 310 are made of the same material, and the first blocking portion 142 and the second blocking portion 320 are made of the same material, when the etching efficiency of the first metal is greater than the etching efficiency of the second metal, it is also beneficial to make the first insulator 141 form a certain indentation relative to the first blocking portion 142, so that the orthographic projection of the top surface of the first insulator 141 on the substrate 110 is located within the orthographic projection of the first blocking portion 142 on the substrate 110.

[0057] Furthermore, the first metal includes aluminum and the second metal includes titanium, which can meet the above-mentioned requirements on etching rate.

[0058] In some embodiments, Figure 2 As shown, the display panel 100 further includes a first electrode layer 120 and a second electrode layer 150. The first electrode layer 120 includes a plurality of first electrode portions 121 arranged at intervals, and the first electrode portion 121 is located on a side of the light-emitting functional portion 131 close to the substrate 110. The second electrode layer 150 includes a plurality of second electrode portions 151 arranged at intervals, and the second electrode portion 151 is located on a side of the light-emitting functional portion 131 away from the substrate 110, and the second electrode portion 151 is electrically connected to the first insulator 141.

[0059] Among them, the first electrode portion 121 is the anode of the OLED light-emitting element, and the second electrode portion 151 is the cathode of the OLED light-emitting element. It can be understood that the partition structure 140 is not only used to partition the adjacent light-emitting functional portion 131, but also used to partition the adjacent second electrode portion 151. On this basis, the second electrode portion 151 is electrically connected to the first insulator 141. In this way, the second electrode portions 151 spaced apart from each other can be electrically connected through the partition structure 140, thereby making the plurality of second electrode portions 151 electrically connected to each other, which is conducive to reducing the number of cathode wirings in the display panel 100. Since the number of cathode wirings will affect the size of the frame area of ​​the display panel 100, it is conducive to improving the level of narrow frame of the display panel 100.

[0060] Furthermore, the display panel 100 may further include a pixel definition layer 160, which is disposed on a side of the first electrode layer 120 away from the substrate 110 and located in the display area 102, and the pixel definition layer 160 has a plurality of first openings 161 for exposing the first electrode portion 121. The light-emitting functional portion 131 is at least partially located in the first openings 161, so that the light-emitting functional portion 131 can contact the first electrode portion 121 through the first openings 161.

[0061] Further, the partition structure 140 defines a plurality of second openings 145, the light-emitting functional parts 131 are located in the second openings 145, and the orthographic projection of the first opening 161 on the substrate 110 is located in the orthographic projection of the second opening 145 on the substrate 110. In this embodiment, the partition structure 140 defines a plurality of second openings 145, and the light-emitting functional parts 131 are disposed in the second openings 145, thereby isolating the light-emitting functional parts 131 in different second openings 145 from each other, so that the partition structure 140 plays a role in isolating adjacent light-emitting functional parts 131.

[0062] In some embodiments, Figures 2 to 4 As shown, the partition structure 140 further includes a first bearing portion 143, which is disposed on a side of the first isolating body 141 close to the substrate 110, and the orthographic projection of the bottom surface of the first isolating body 141 on the substrate 110 is located within the orthographic projection of the top surface of the first bearing portion 143 on the substrate 110. The isolation column 300 further includes a second bearing portion 330, which is disposed on a side of the second isolating body 310 close to the substrate 110, and the orthographic projection of the bottom surface of the second isolating body 310 on the substrate 110 is located within the orthographic projection of the top surface of the second bearing portion 330 on the substrate 110. The second bearing portion 330 and the first bearing portion 143 are disposed on the same layer and made of the same material.

[0063] In this embodiment, the isolation column 300 further includes a second bearing portion 330, which is located on the side of the second isolation body 310 close to the substrate 110, and the orthographic projection of the bottom surface of the second isolation body 310 on the substrate 110 is located within the orthographic projection of the top surface of the second bearing portion 330 on the substrate 110. In other words, the isolation column 300 includes the second bearing portion 330, the second isolation body 310 and the second blocking portion 320 in sequence from the end close to the substrate 110 to the end far from the substrate 110, so that the isolation column 300 presents an "I"-shaped structure as a whole, which is conducive to further improving the effect of isolating the light-emitting functional layer 130, and at the same time can extend the water and oxygen intrusion path, better block water vapor and oxygen, and improve the packaging effect.

[0064] On the other hand, by providing the first bearing portion 143 at the bottom of the first isolator 141, it is helpful to reduce the resistance of the second electrode portion 151, thereby helping to reduce the voltage drop of the second electrode layer 150, and further helping to improve the uniformity of the display brightness of the display panel. In addition, based on the fact that the partition structure 140 also includes the first bearing portion 143, the manufacturing process of the partition structure 140 is generally as follows: sequentially depositing a third material layer for making the first bearing portion 143, a first material layer for making the first isolator 141, and a second material layer for making the first blocking portion 142. Then, the third material layer, the first material layer, and the second material layer are patterned using a photolithography process to manufacture the first bearing portion 143, the first isolator 141, and the first blocking portion 142.

[0065] On the basis that the first isolator 141 and the second isolator 310 are arranged in the same layer and made of the same material, and the second barrier 320 and the first barrier 142 are arranged in the same layer and made of the same material, the second bearing part 330 and the first bearing part 143 are further arranged in the same layer and made of the same material, so that the third material layer can also be used to make the second bearing part 330, the first material layer can also be used to make the second isolator 310, and the second material layer can also be used to make the second barrier 320, so that after the third material layer, the first material layer and the second material layer are patterned, the second bearing part 330, the second isolator 310 and the second barrier 320 can also be made. This is conducive to simplifying the manufacturing process of the display panel and reducing the manufacturing cost.

[0066] Further, the material of the second bearing part 330 is the second metal. In the process of patterning the third material layer, the first material layer and the second material layer, an etching solution is needed to etch the third material layer, the first material layer and the second material layer, so as to produce the first bearing part 143 and the second bearing part 330, the first isolating body 141 and the second isolating body 310, and the first blocking part 142 and the second blocking part 320. In this embodiment, the material of the second isolating body 310 is the first metal, the material of the second bearing part 330 and the second blocking part 320 is the second metal, and the etching efficiency of the first metal is greater than the etching efficiency of the second metal. In this way, within the same etching time, the etching amount of the first metal is greater than the etching amount of the second metal, so that the manufactured second insulator 310 can be retracted to a certain extent relative to the second supporting part 330 and the second blocking part 320, so that the orthographic projection of the bottom surface of the second insulator 310 on the substrate 110 is located within the orthographic projection of the top surface of the second supporting part 330 on the substrate 110, and the orthographic projection of the top surface of the second insulator 310 on the substrate 110 is located within the orthographic projection of the second blocking part 320 on the substrate 110.

[0067] Similarly, since the first bearing part 143 and the second bearing part 330 are made of the same material, the first insulator 141 and the second insulator 310 are made of the same material, and the first blocking part 142 and the second blocking part 320 are made of the same material, when the etching efficiency of the first metal is greater than the etching efficiency of the second metal, it is also beneficial to make the manufactured first insulator 141 form a certain indentation relative to the first bearing part 143 and the first blocking part 142, so that the orthographic projection of the bottom surface of the first insulator 141 on the substrate 110 is located within the orthographic projection of the top surface of the first bearing part 143 on the substrate 110, and the orthographic projection of the top surface of the first insulator 141 on the substrate 110 is located within the orthographic projection of the first blocking part 142 on the substrate 110.

[0068] In some embodiments, the isolation column 300 is an annular structure disposed around the opening area 101 , so that the isolation column 300 can form an annular closed structure, which can better prevent external water vapor and oxygen from passing through the isolation column 300 and entering the display area 102 .

[0069] In one embodiment, there may be multiple isolation columns 300, the diameters of the annular structures formed by the isolation columns 300 are different, and the centers of the multiple annular structures coincide with each other. By providing multiple concentric isolation columns 300, the effect of blocking water vapor and oxygen can be further improved.

[0070] Furthermore, there is a gap between two adjacent isolation columns 300 . Preferably, the orthographic projections of the plurality of isolation columns 300 on the substrate 110 have no overlapping areas. Such an arrangement is conducive to improving the effect of blocking water vapor and oxygen.

[0071] In some embodiments, Figure 2 or Figure 5 As shown, the display panel 100 further includes a first encapsulation layer 170, which includes a plurality of encapsulation parts 171 arranged at intervals, and the encapsulation parts 171 are used to encapsulate the light-emitting functional parts 131. In this way, the light-emitting functional parts 131 can be independently encapsulated and protected one by one through the encapsulation parts 171.

[0072] Furthermore, if Figure 5 , Figure 6 As shown, the first encapsulation layer 170 further includes a second encapsulation portion 172, which is located in the non-display area 103 and covers the isolation column 300. Thus, the first encapsulation layer 170 can not only encapsulate and protect the light-emitting functional portion 131 in the display area 102, but also make the non-display area 103 in an encapsulated and protected state, so as to further reduce the possibility of water vapor and oxygen entering the display area 102.

[0073] Furthermore, if Figure 5 , Figure 6 As shown, the display panel 100 may further include a second encapsulation layer 180, which is disposed on a side of the first encapsulation layer 170 away from the substrate 110, and covers the top surface of the first encapsulation layer 170 and the partition structure 140. The first encapsulation layer 170 encapsulates the light-emitting functional part 131 one by one through the encapsulation parts 171 arranged at intervals, and the second encapsulation layer 180 may be encapsulated on the entire surface, thereby further improving the encapsulation performance.

[0074] Furthermore, the display panel 100 may further include a third encapsulation layer 190, which is disposed on a side of the second encapsulation layer 180 away from the substrate 110. Thus, multi-layer encapsulation is achieved through the first encapsulation layer 170, the second encapsulation layer 180 and the third encapsulation layer 190 to further improve encapsulation performance.

[0075] Furthermore, the first encapsulation layer 170 and the third encapsulation layer 190 may be inorganic film layers, and the second encapsulation layer 180 may be an organic film layer. The inorganic film layer mainly serves to isolate water vapor and air, and the organic film layer is mainly used to provide flexibility. In addition, the second encapsulation layer 180 is an organic film layer, which can also flatten the first encapsulation layer 170.

[0076] Furthermore, if Figure 5 , Figure 6As shown, the display panel 100 also includes at least one retaining wall 400, which is arranged in the non-display area 103, and is used to block the second encapsulation layer 180; the second encapsulation layer 180 overlaps with a side of the retaining wall 400 close to the display area 102; the second encapsulation layer 180 also covers the retaining wall 400.

[0077] The second encapsulation layer 180 is an organic film layer, which is made by inkjet printing. Specifically, the manufacturing process is to form an organic glue on the top surface of the first encapsulation layer 170 and the partition structure 140 by inkjet printing, and then form the second encapsulation layer 180 after the organic glue is cured. In this embodiment, a retaining wall 400 is provided in the non-display area 103, and the retaining wall 400 can block the organic glue that has fluidity before curing, thereby preventing the organic glue from flowing to the opening area 101.

[0078] Furthermore, the relative position relationship between the retaining wall 400 and the isolation column 300 can be selected in a variety of ways and can be set according to design requirements. Figure 5 As shown, there are multiple isolation columns 300, and the retaining wall 400 is disposed on a side of the multiple isolation columns 300 away from the display area 102. For example, in another embodiment, Figure 6 As shown, there are multiple isolation columns 300 , and the retaining wall 400 is disposed between two of the isolation columns 300 .

[0079] The second aspect of the present application provides a display device, including the display panel in any embodiment of the first aspect, wherein the display device can be, for example, a display, a television, a digital camera, a mobile phone, a tablet computer, a navigator, or any other product or component with a display function.

[0080] In the display device in the embodiment of the present application, the display panel 100 is provided with a partition structure 140 in the display area 102, and the partition structure 140 is used to separate the adjacent light-emitting functional parts 131, and an isolation column 300 is provided in the non-display area 103 between the display area 102 and the opening area 101, and the isolation column 300 is used to prevent water vapor and oxygen in the opening area from entering the display area. Among them, the isolation column 300 and the partition structure 140 are arranged in the same layer and made of the same material, so that the isolation column 300 and the partition structure 140 can be manufactured in the same manufacturing process, and the manufacturing of the isolation column 300 and the manufacturing of the partition structure 140 can share a mask plate. In this way, it is beneficial to reduce the manufacturing cost of the display panel and also beneficial to improve the production efficiency.

[0081] 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.
