[0002] In the manufacturing process of an Organic Light Emitting Diode (OLED) display panel, the maskless deposition and photolithography patterning pixel method can greatly increase the effective light-emitting area (aperture ratio) of the display panel, which is beneficial to greatly increasing the pixel density. In order to achieve high resolution and colorization of passive matrix OLEDs, a cathode isolation column structure is introduced. That is, in the device manufacturing, instead of using a metal template, an insulating partition is made on the substrate before depositing the organic thin film and the metal cathode, and finally different pixels of the device are separated to achieve pixel array arrangement. This cathode isolation column structure is also called a hanging structure.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

"And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0031] In the manufacturing process of an Organic Light Emitting Diode (OLED) display panel, the maskless deposition and photolithography patterning pixel method can significantly increase the effective light-emitting area (aperture ratio) of the display panel, which is beneficial to significantly increasing the pixel density. To achieve high resolution and colorization of passive matrix OLEDs, a cathode isolation column structure is introduced, that is, in device fabrication, instead of using a metal template, an insulating partition is fabricated on the substrate before depositing the organic thin film and the metal cathode, and finally, different pixels of the device are separated to achieve pixel array arrangement. This cathode isolation column structure is also called a hanging structure.

[0032] The existing hanging structure with a metal layer is provided between adjacent sub-pixels. However, due to the fixed size and resistance of the metal layer in the hanging structure, it is not conducive to adjusting the aperture ratio of the sub-pixel by adjusting the size of the hanging structure. Therefore, how to adjust the aperture ratio of the sub-pixel based on the existing hanging structure is an urgent problem to be solved.

[0033] To solve the above technical problems, as shown in Figures 1 to 4 a display panel is provided, including a driving substrate 100, a pixel definition layer 200, a hanging structure 300, and a plurality of sub-pixels 500. The pixel definition layer 200 is disposed on one side surface of the driving substrate 100, and the pixel definition layer 200 protrudes from the driving substrate 100 to form a pixel accommodation area. The hanging structure 300 is disposed on the pixel definition layer 200. The hanging structure 300 includes a first hanging structure 310 and a second hanging structure 320. The first hanging structure 310 includes a first metal layer 311 and a first insulating layer 312 stacked in sequence from a direction close to the driving substrate 100 to a direction away from the driving substrate 100, and has a center coinciding with the vertex of the first virtual square 400. The second hanging structure 320 includes a second insulating layer 321 disposed on the driving substrate 100. The second hanging structure 320 is spaced from the first hanging structure 310, and the second hanging structure 320 has a center coinciding with the center of the first virtual square 400. A plurality of sub-pixels 500 are disposed in the pixel accommodation area. The sub-pixels 500 have a center coinciding with the side of the first virtual square 400, and are electrically connected through the first metal layer 311 between adjacent first hanging structures 310.

[0034] The driving substrate 100 is used to drive the sub-pixels 500 to emit light. The overhanging structure 300 is disposed on the pixel defining layer 200 between adjacent sub-pixels 500 to play an isolation role. The center of the first overhanging structure 310 of the overhanging structure 300 coincides with the vertex of the first virtual square 400, and the center of the second overhanging structure 320 coincides with the center of the first virtual square 400. Within the range of the first virtual square 400, the first overhanging structure 310 surrounds the second overhanging structure 320. The first overhanging structure 310 includes a first metal layer 311 and a first insulating layer 312 stacked in sequence from the direction close to the driving substrate 100 to the direction away from the driving substrate 100. The adjacent sub-pixels 500 are connected through the first metal layer 311, which can improve the uniformity of the sub-pixels 500 and reduce the IR Drop of the display panel. The second overhanging structure 320 includes a second insulating layer 321 disposed on the driving substrate 100 and located between some adjacent sub-pixels 500. Since the metal layer and its resistance size do not need to be considered compared with the first overhanging structure 310, the volume of the second overhanging structure 320 can be adjusted to control the aperture ratio of the display panel.

[0035] In some embodiments, referring to Figure 1 or Figure 2 As shown, the first virtual square 400 is a reference pattern defined on the display panel and does not have a substantial structure. It is configured as a right-angled quadrilateral. The first virtual square 400 includes four vertices A, B, C, and D. The center of each first overhanging structure 310 coincides with vertex A, vertex B, vertex C, and vertex D respectively, and the two first overhanging structures 310 located at adjacent vertices are spaced apart to form a spacing. The second overhanging structure 320 is disposed at the center formed by the surrounding of the first overhanging structure 310. The second overhanging structure 320 is located at the center of the first virtual square 400, that is, the second overhanging structure 320 is located at the intersection point E of the connection line between vertex A and vertex C and the connection line between vertex B and vertex D of the first virtual square 400. The center of the sub-pixel 500 is located on the side of the first virtual square 400 and between the adjacent first overhanging structures 310. The first overhanging structure 310, the second overhanging structure 320, and the sub-pixels 500 on multiple first virtual squares 400 are extended in the first direction and the second direction to form the display panel.

[0036] In some embodiments, the material of the first metal layer 311 may include but is not limited to metal materials such as Al (aluminum), Au (gold), Ag (silver), and MgAg (aluminum-magnesium alloy). The material of the first insulating layer 312 and the second insulating layer 321 is one of a non-conductive organic material and a non-conductive inorganic material. Among them, the non-conductive inorganic material includes but is not limited to an inorganic silicon-containing material. For example, the silicon-containing material includes silicon oxide or nitride or a combination thereof. Among them, the non-conductive organic material includes a negative photosensitive organic material. For example, the negative photosensitive organic material includes but is not limited to a negative photoresist. In the first overhang structure 310, the first metal layer 311 having metal materials such as Al (aluminum), Au (gold), Ag (silver), and MgAg (aluminum-magnesium alloy) is not easy to adjust the size in the process, and considering that the size of the first metal layer 311 will affect the uniformity of the display panel. Then the display panel is also adjusted as little as possible on the existing design technology. Since the second overhang structure 320 only plays an isolation role and is made of non-conductive organic material or non-conductive inorganic material, it only needs to play an isolation role in design, and its material is also easy to adjust the size of its structure. Therefore, the aperture ratio between the sub-pixels 500 can be adjusted by adjusting the size of the second overhang structure 320.

[0037] In some embodiments, the driving substrate 100 includes a substrate and a driving circuit layer. The display panel having the substrate and the driving circuit layer is an active OLED.

[0038] In another embodiment, the driving circuit layer of the driving substrate 100 is separately provided. The display panel having a substrate but not including a driving circuit layer is a passive OLED. The passive OLED includes a plurality of parallel and spaced anodes 501 and a plurality of parallel and spaced cathodes 503, and the anodes 501 and the cathodes 503 are cross-arranged to form an addressing circuit, and are scanned and driven by an external PCB circuit board.

[0039] Furthermore, the substrate may be a glass substrate or a flexible substrate. The material of the flexible substrate is polyimide (PI). The driving circuit layer may be a thin film transistor (TFT) circuit layer, and the TFT circuit layer is used to drive the light-emitting layer 502 of the OLED. The specific TFT circuit layer includes a plurality of driving circuit units arranged in an array, and each driving circuit unit may include a TFT device and a capacitor. Each driving circuit unit corresponds to an anode 501 and a light-emitting layer 502. The TFT device is a low temperature polysilicon (LTPS) type or a metal oxide semiconductor (MOS) type, such as a metal oxide semiconductor type of indium gallium zinc oxide (IGZO).

[0040] In some embodiments, the material of the pixel defining layer 200 may be an organic material, or one of an organic material or an inorganic material provided with an inorganic coating thereon. The organic material of the pixel defining layer 200 includes, but is not limited to, polyimide. The inorganic material of the pixel defining layer 200 includes, but is not limited to, silicon oxide (SiO2), silicon nitride (Si3N4), silicon oxynitride (Si2N2O), magnesium fluoride (MgF2), or a combination thereof.

[0041] In some embodiments, referring to Figure 3 As shown, in the first overhanging structure 310, the first insulating layer 312 has a bottom close to the first metal layer 311 and a top far from the first metal layer 311, and the sidewall of the bottom is concave relative to the sidewall of the top. Wherein, the bottom of the first insulating layer 312 only covers a part of the first metal layer 311, and the projection of the first metal layer 311 on the driving substrate 100 completely covers the projection of the bottom of the first insulating layer 312 on the driving substrate 100, so that the cathode 503 of the first sub-pixel 510 can overlap the area of the first metal layer 311 not covered by the bottom of the first insulating layer 312.

[0042] Furthermore, the projection of the top of the first insulating layer 312 on the driving substrate 100 completely covers the projection of the first metal layer 311 on the driving substrate 100, and at least a part of the top of the first insulating layer 312 is suspended relative to the bottom of the first insulating layer 312, so as to change the evaporation angle through the top of the first insulating layer 312 during evaporation deposition.

[0043] In some embodiments, referring to Figure 4 As shown, in the second overhanging structure 320, the second insulating layer 321 has a top far from the pixel defining layer 200 and a bottom close to the pixel defining layer 200. The bottom of the second insulating layer 321 is in contact with the pixel defining layer 200. The projection of the top of the second insulating layer 321 on the driving substrate 100 completely covers the projection of the bottom of the second insulating layer 321 on the driving substrate 100, and at least a part of the top of the first insulating layer 312 is suspended relative to the bottom of the first insulating layer 312, so as to change the evaporation angle through the top of the first insulating layer 312 during evaporation deposition.

[0044] In some embodiments, the display panel includes a plurality of pixels for emitting lights of different colors, and the plurality of pixels emit lights to display an image. Each pixel realizes the display of a white picture by superimposing and mixing sub-pixels 500 of three colors, red, green, and blue, and displays different color pictures by controlling the light-emitting degrees of sub-pixels 500 of different colors.

[0045] As described above, the driving substrate 100 includes a substrate and a driving circuit layer. The sub-pixels 500 are driven by the driving circuit layer to emit red, green, and blue light, and different color pictures are displayed by controlling the light-emitting degrees of the sub-pixels 500 of different colors. With reference to the first virtual square 400, the first overhanging structure 310 is respectively disposed at the vertices of the first virtual square 400, the second overhanging structure 320 is disposed at the center of the first virtual square 400, and the sub-pixels 500 are disposed between adjacent first overhanging structures 310. Thus, the aperture ratio of the display panel can be increased by adjusting the volume of the second overhanging structure 320.

[0046] In some embodiments, as combined Figure 1 and Figure 2 shown, in the first virtual square 400, the sub-pixel 500 includes a first sub-pixel 510, a second sub-pixel 520, and a third sub-pixel 530. Two first sub-pixels 510 are configured, and one second sub-pixel 520 and one third sub-pixel 530 are configured. The first virtual square 400 has two corresponding sets of sides. The centers of the two first sub-pixels 510 are located on one set of corresponding sides, and the centers of the second sub-pixel 520 and the third sub-pixel 530 are respectively located on the other set of corresponding sides. In the first virtual square 400, the first sub-pixel 510 can be extended and disposed in the first direction and the second direction. When the first sub-pixel 510 is disposed in the first direction, the second sub-pixel 520 and the third sub-pixel 530 are alternately disposed in the second direction; when the first sub-pixel 510 is disposed in the second direction, the second sub-pixel 520 and the third sub-pixel 530 are alternately disposed in the first direction. And the second sub-pixel 520, the third sub-pixel 530, and the two first sub-pixels 510 are correspondingly distributed on the sides AB, BC, BD, and AD of the first virtual square 400 according to the above rules. A pixel is formed by adjacent first sub-pixels 510, second sub-pixels 520, and third sub-pixels 530 for emitting light of different colors.

[0047] Furthermore, the centers of the first sub-pixel 510, the second sub-pixel 520, and the third sub-pixel 530 are all located at the centers of the sides of the first virtual square 400. So as to form uniformly distributed pixels on the display panel, and a more uniform picture can be displayed through the uniformly distributed pixels on the display panel.

[0048] In some embodiments, as Figure 1As shown, two first sub-pixels 510 are arranged on two corresponding sides of the first virtual square 400 along the second direction, and the centers of the two first sub-pixels 510 coincide with the centers of the corresponding two sides; the second sub-pixel 520 and the third sub-pixel 530 are respectively arranged on two corresponding sides of the first virtual square 400 along the first direction, and the centers of the second sub-pixel 520 and the third sub-pixel 530 coincide with the centers of the corresponding two sides. Through the above two designs, arranging the sub-pixels 500 and the overhanging structure 300 distributed on a single first virtual square 400 can form a display panel.

[0049] In another embodiment, as Figure 2 shown, two first sub-pixels 510 are arranged along the first direction, the second sub-pixel 520 and the third sub-pixel 530 are arranged along the second direction, there is a first virtual connection line between the two first sub-pixels 510, and there is a second virtual connection line between the second sub-pixel 520 and the third sub-pixel 530, and the intersection point of the first virtual connection line and the second virtual connection line coincides with the center of the first virtual square 400. Two first sub-pixels 510 are arranged on two corresponding sides of the first virtual square 400 along the first direction, and the centers of the two first sub-pixels 510 coincide with the centers of the corresponding two sides; the second sub-pixel 520 and the third sub-pixel 530 are respectively arranged on two corresponding sides of the first virtual square 400 along the second direction, and the centers of the second sub-pixel 520 and the third sub-pixel 530 coincide with the centers of the corresponding two sides. Through the above two designs, arranging the sub-pixels 500 and the overhanging structure 300 distributed on a single first virtual square 400 can form a display panel.

[0050] In some embodiments, the first sub-pixel 510 is configured to emit green light, the second sub-pixel 520 is configured to emit red light, and the third sub-pixel 530 is configured to emit blue light. Different color pictures are displayed by controlling the light-emitting degrees of different color sub-pixels 500.

[0051] In some embodiments, the sub-pixel 500 includes an anode 501, a light-emitting layer 502, and a cathode 503 that are stacked from near the pixel defining layer 200 to away from the pixel defining layer 200, and the cathode 503 is electrically connected to the first metal layer 311 of the first overhanging structure 310. The anode 501 is disposed on the pixel defining layer 200, the pixel defining layer 200 covers part of the anode 501, the organic light-emitting layer 502 is disposed on the anode 501, and the cathode 503 is disposed on the organic light-emitting layer 502, thereby forming the sub-pixel 500. By electrically connecting the cathode 503 to the first metal layer 311 of the first overhanging structure 310, the uniformity of the display panel can be increased.

[0052] In some embodiments, in combination with Figure 3 or Figure 4As shown, the sub-pixel 500 further includes an insulating protective layer 504 disposed on the cathode 503, and the insulating protective layer 504 is used to insulate and protect the cathode 503 and the overhanging structure 300.

[0053] In some embodiments, the anode 501 is disposed between the pixel definition layer 200 and the substrate. The anode 501 is spaced apart on one surface of the substrate. The material of the anode 501 includes but is not limited to chromium, titanium, gold, silver, copper, aluminum, ITO, combinations thereof, or other suitable conductive materials. The organic light-emitting layer 502 is configured to emit red, blue, or green light when powered on, and the organic light-emitting layer 502 may include one or more of a Hole Injection Layer (HIL), a Hole Transfer Layer (HTL), an Emitting Layer (EML), and an Electron Transfer Layer (ETL). The cathode 503 is disposed on a side of the organic light-emitting layer 502 away from the anode 501, and the material of the cathode 503 includes but is not limited to chromium, titanium, gold, silver, copper, aluminum, ITO, combinations thereof, or other suitable conductive materials. The material of the cathode 503 may be the same as or different from the material of the anode 501, which is specifically set according to actual circumstances.

[0054] In some embodiments, the pixel definition layer 200 is fabricated on the anode 501 of the sub-pixel 500, and the pixel definition layer 200 is exposed and developed to form a pixel opening located in the pixel accommodation region above the anode 501 of each sub-pixel 500, and the pixel definition layer 200 partially covers the anode 501 of the sub-pixel 500. An organic light-emitting material is evaporated on the pixel definition layer 200 and the anode 501 to form the organic light-emitting layer 502, and a cathode 503 material is evaporated on the organic light-emitting layer 502 to form the cathode 503.

[0055] In some embodiments, referring to Figure 5 and Figure 6As shown, the display panel further includes a touch layer 600. The touch layer 600 includes a plurality of spaced-apart touch blocks 610, and the touch blocks 610 are located on the corresponding second overhanging structures 320. Since the first metal layer 311 is not provided on the second overhanging structure 320, it can be used to set the touch layer or for the routing of the touch layer. There is a signal blank area above the second overhanging structure 320. By setting the touch blocks 610 of the touch layer 600 above each corresponding second overhanging structure 320, the routing space of the display panel can be saved. The touch layer 600 can be two layers arranged in a stacked manner or a single layer arranged on the same layer. When the touch layer 600 is two layers arranged in a stacked manner, the two corresponding touch blocks 610 of the two layers form a capacitive structure; when the touch layer 600 is a single layer arranged on the same layer, two adjacent touch blocks 610 form a capacitive structure. Thus, touch signals are received and transmitted.

[0056] In some embodiments, such as Figure 5 As shown, the display panel further includes a connection bridge 620, which extends along the side of the second virtual square 700. The connection bridge 620 is connected between adjacent touch blocks 610. The second virtual square 700 is similar to the first virtual square 400, and both are reference patterns. The first virtual square 400 is a reference pattern corresponding to the overhanging structure 300 and the sub-pixels 500. The second virtual square 700 is a reference pattern corresponding to the touch layer 600. Each touch block 610 has a center that coincides with the vertex of the second virtual square 700. If the touch block 610 is a square that can be approximated as a right-angled quadrilateral, the center of the touch block 610 is the intersection point of the connecting lines of the corresponding vertices of the right-angled quadrilateral. The connection bridge 620 extends along the side of the second virtual square 700 and is connected between adjacent touch blocks 610 to form touch units. A plurality of touch units respectively form receiving electrodes or transmitting electrodes to receive or transmit touch signals.

[0057] In another embodiment, such as Figure 6 As shown, the display panel further includes a connection bridge 620, which extends along the virtual connection line between two opposite vertices of the second virtual square 700. The connection bridge 620 is connected between adjacent touch blocks 610. If the touch block 610 is a square that can be approximated as a right-angled quadrilateral, the center of the touch block 610 is the intersection point of the connecting lines of the corresponding vertices of the right-angled quadrilateral. The connection bridge 620 extends along the virtual connection line between two opposite vertices of the second virtual square 700 and is connected between adjacent touch blocks 610 to form touch units. A plurality of touch units respectively form receiving electrodes or transmitting electrodes to receive or transmit touch signals.

[0058] In this application, the driving substrate 100 includes a substrate and a driving circuit layer. The sub-pixels 500 are driven by the driving circuit layer to emit red, green, and blue lights, and different color pictures are displayed by controlling the light-emitting degrees of sub-pixels 500 of different colors. With reference to the first virtual square 400, a plurality of first overhanging structures 310 are respectively arranged at the vertices of the first virtual square 400, the second overhanging structure 320 is arranged at the center of the first virtual square 400, and the sub-pixels 500 are arranged between adjacent first overhanging structures 310. Thus, the aperture ratio of the display panel can be increased by adjusting the volume of the second overhanging structure 320. Since the first metal layer 311 is not provided on the second overhanging structure 320, a touch block or a trace can be provided, so that a signal blank area can be formed above the second overhanging structure 320, and the touch blocks 610 of the touch layer 600 are arranged above the corresponding second overhanging structures 320, which can save the trace space of the display panel.
