Description

Technical Field

[0002] In the manufacturing process of organic light-emitting devices, it is inevitable that there will be defects such as dust particles, burrs, pinholes, cracks, etc., and the distance between the anode and the cathode of the organic light-emitting device is usually very small. At the defect point, the anode and the cathode may directly contact each other and cause a short circuit, or the organic layer between the anode and the cathode may be thinner than other positions. When the organic light-emitting device is working, the current tends to pass through such defect point rather than other positions, causing heat to accumulate at such defect point, resulting in damage to the quality and reliability of the entire organic light-emitting device.

[0036] The utility model provides a light-emitting panel. Figure 1 It is a cross-sectional schematic diagram of a light-emitting panel provided by the utility model. Figure 2 is a top view schematic diagram of a light emitting panel provided by an embodiment of the utility model, referring to Figure 1 and Figure 2 , the light emitting panel includes:

[0037] A substrate 10, an anti-short circuit layer 20, a first insulating layer 30 and at least one light emitting unit 40; the anti-short circuit layer 20 is arranged on one side of the substrate 10, the first insulating layer 30 is arranged on a side of the anti-short circuit layer 20 away from the substrate 10, the first insulating layer 30 covers the anti-short circuit layer 20, and the light emitting unit 40 is arranged on a side of the first insulating layer 30 away from the substrate 10;

[0038] Each light-emitting unit 40 includes a first electrode layer 41, a light-emitting layer 42 and a second electrode layer 43 arranged in sequence, and the light-emitting layer 42 is arranged on the side of the first electrode layer 41 away from the substrate 10; the first electrode layer includes a plurality of light-transmitting electrode sublayers 411 arranged at intervals from each other; the anti-short-circuit layer 20 includes a plurality of light-transmitting resistor structures 21 arranged at intervals, and each light-transmitting resistor structure 21 is electrically connected to a light-transmitting electrode sublayer 411 through a through hole in the first insulating layer 30.

[0039] in, Figure 1 yes Figure 2 A cross-sectional view of the light-emitting panel along section line AA. Figure 2 Only the substrate 10 and the anti-short-circuit layer 20 are shown exemplarily. The first insulating layer 30 may be a silicon oxide insulating layer. The light-emitting panel may include a plurality of light-emitting units 40, and each light-emitting unit 40 may be independently controlled and independently emit light. Each light-emitting unit 40 may include a plurality of sub-light-emitting areas, and each light-transmitting electrode sublayer 411 and its corresponding light-emitting layer 42 and the second electrode layer 43 are a sub-light-emitting area. Exemplarily, the light-emitting panel may include 10*10 light-emitting units 40, and each light-emitting unit 40 may include 10*10 sub-light-emitting areas. The first electrode layer 41 is a light-transmitting electrode, and the second electrode layer 43 is a reflective electrode. Exemplarily, the first electrode layer 41 is an anode, and the second electrode layer 43 is a cathode, or the first electrode layer 41 is a cathode, and the second electrode layer 43 is an anode.

[0040] Each sub-light-emitting area corresponds to a light-transmitting electrode sub-layer 411 and a light-transmitting resistor structure 21. The light-transmitting resistor structure 21 and the light-transmitting electrode sub-layer 411 can be made of the same material, and transparent metal oxides such as ITO can be used as an example. The light-transmitting resistor structure 21 is electrically connected to the light-transmitting electrode sub-layer 411. When there is a defect in the area corresponding to the light-transmitting electrode sub-layer 411 and a short circuit occurs, or when the light-emitting layer 42 between the first electrode layer 41 and the second electrode layer 43 is thin, the light-transmitting resistor structure 21 can reduce the current flowing through the sub-light-emitting area corresponding to the light-transmitting electrode sub-layer 411, so as to avoid excessive heat generation affecting other areas.

[0041] The first electrode layer 41 of a light-emitting unit 40 in the light-emitting panel of the embodiment of the utility model includes a plurality of mutually spaced transparent electrode sublayers 411. When a defect occurs at a certain position in the light-emitting unit 40, the transparent electrode sublayer 411 corresponding to the position is independent of the other transparent electrode sublayers 411. The defect will only affect the sub-light-emitting area corresponding to the transparent electrode sublayer 411, but will not affect other sub-light-emitting areas, thereby reducing the failure area. In addition, each transparent electrode sublayer 411 is connected to a transparent resistor structure 21. The transparent resistor structure 21 is in a different layer from the transparent electrode sublayer 411. The transparent resistor structure 21 can be set to have a larger resistance, which can reduce the current of the sub-light-emitting area where the defect is located, avoid excessive heat generation and affect other sub-light-emitting areas, and improve the reliability of the light-emitting panel. In addition, the transparent resistor structure 21 is in a different layer from the light-emitting unit 40, which will not affect the area of ​​the light-emitting area, thereby ensuring that the light-emitting panel has a larger aperture ratio. In summary, the light-emitting panel of the present embodiment can reduce the failure area caused by defects, improve the reliability of the light-emitting panel, and ensure that the light-emitting panel has a larger aperture ratio.

[0042] Optionally, the light-transmitting resistor structure 21 includes a plurality of resistor segments 211 connected in sequence, the first insulating layer 30 is filled between adjacent resistor segments 211 , and the resistor segments 211 and the first insulating layer 30 are alternately arranged on the surface of the substrate 10 .

[0043] Among them, the refractive index of the resistor segment 211 and the first insulating layer 30 is different. On the surface of the substrate 10, the resistor segment 211 and the first insulating layer 30 are arranged alternately, which can play a role in light extraction. Exemplarily, on the surface of the substrate 10, the multiple resistor segments 211 of each light-transmitting resistor structure 21 are arranged alternately with the first insulating layer 30, and the vertical projection of each light-transmitting resistor structure 21 on the substrate 10 is located within the vertical projection of the light-transmitting electrode sublayer 411 electrically connected to it on the substrate 10. The light emitted by the sub-light-emitting area corresponding to each light-transmitting electrode sublayer 411 can be better emitted through the light-transmitting resistor structure 21, and the sub-light-emitting area corresponding to each light-transmitting electrode sublayer 411 has a high light extraction rate.

[0044] In this embodiment, a light-transmitting resistor structure 21 includes a plurality of resistor segments 211. Since the refractive index of the resistor segments 211 is different from that of the first insulating layer 30, the resistor segments 211 and the first insulating layer 30 are alternately arranged on the surface of the substrate 10, which can play a role in light extraction and improve the light extraction rate of the light-emitting panel.

[0045] Optionally, the line width of the resistance segment 211 is greater than or equal to 1 micron and less than or equal to 5 microns;

[0046] In the same light-transmitting resistor structure 21 , the distance D between the resistor segments 211 is greater than or equal to 1 micrometer and less than or equal to 5 micrometers.

[0047] Specifically, if the line width and spacing D of the resistor segment 211 are too small, the process requirements are too high, and if they are too large, the light extraction effect may be affected. By setting the line width of the resistor segment 211 to be greater than or equal to 1 micron and less than or equal to 5 microns, while reducing the process difficulty, it is ensured that the resistor segment 211 and the first insulating layer 30 are alternately arranged to achieve a better light extraction effect.

[0048] Exemplarily, the line width of the resistor segment 211 is greater than or equal to 1 micron and less than or equal to 3 microns, and in the same light-transmitting resistor structure 21, the spacing D between the resistor segments 211 is greater than or equal to 1 micron and less than or equal to 3 microns. For example, the line width of the resistor segment 211 can be 1 micron, 2 microns, or 3 microns, and the spacing D between the resistor segments 211 can be 1 micron, 2 microns, or 3 microns, etc.

[0049] Optional, Figure 3 is a schematic diagram of a light-transmitting resistor structure provided by an embodiment of the utility model, Figure 4 is a schematic diagram of another light-transmitting resistor structure provided by an embodiment of the utility model. Figure 5 is a schematic diagram of another light-transmitting resistor structure provided by an embodiment of the utility model. Figure 6 Schematic diagram of another light-transmitting resistor structure provided by the embodiment of the utility model. Figure 2-Figure 6 The light-transmitting resistor structure 21 is at least one of a spiral shape, a sawtooth wave shape or a rectangular wave shape.

[0050] Specifically, refer to Figure 2-Figure 4 The light-transmitting resistor structure 21 may be spiral-shaped, that is, the light-transmitting resistor structure 21 includes a plurality of resistor segments 211 arranged in a spiral shape. Figure 5 The light-transmitting resistor structure 21 may also be in the shape of a rectangular wave, see Figure 6 , the light-transmitting resistor structure 21 can also be sawtooth-shaped. The light-transmitting resistor structure 21 in spiral, sawtooth-shaped and rectangular wave shapes can be longer in length, and the light-transmitting resistor structure 21 can have a larger resistance, which can better reduce the current of the sub-light-emitting area where the defect is located, avoid excessive heat generation and affect other sub-light-emitting areas, and improve the reliability of the light-emitting panel. In addition, the resistor segments 211 are arranged closely, and on the surface of the substrate, the resistor segments 211 and the first insulating layer can achieve a better light extraction effect and improve the light extraction rate.

[0051] Optional, reference Figure 3-Figure 6 , the vertical projection of the light-transmitting resistor structure 21 on the substrate is located within the vertical projection of the light-transmitting electrode sublayer 411 electrically connected thereto on the substrate;

[0052] The vertical projection shape of the light-transmitting electrode sublayer 411 on the substrate is a triangle, a square, a rectangle or a hexagon.

[0053] Specifically, the vertical projection of the light-transmitting resistor structure 21 on the substrate is located within the vertical projection of the light-transmitting electrode sublayer 411 electrically connected to it on the substrate. The light-transmitting resistor structure 21 can be evenly arranged within the projection of the light-transmitting electrode sublayer 411, so that the light-transmitting resistor structure 21 can have a larger length and a larger resistance, and the light-transmitting resistor structure 21 can play a better role in extracting light from the sub-light-emitting areas, so that each sub-light-emitting area can have a larger light output rate.

[0054] The light-transmitting electrode sublayer 411 can also be other polygons, which are not specifically limited in this embodiment. The manufacturing process of the light-transmitting electrode sublayer 411 in the shape of a triangle, square, rectangle or hexagon is simpler, and the arrangement of the light-transmitting resistor structure 21 in the region of a triangle, square, rectangle or hexagon is more conducive to improving the resistance and light extraction function of the light-transmitting resistor structure 21.

[0055] Optional, continue to refer to Figure 1 The surface of the first insulating layer 30 away from the substrate 10 is undulating, each transparent electrode sublayer 411 is undulating with the surface of the first insulating layer 30 away from the substrate 10, the light-emitting layer 42 is undulating with the surface of the transparent electrode sublayer 411 away from the substrate 10, and the second electrode layer 43 is undulating with the surface of the light-emitting layer 42 away from the substrate 10.

[0056] Specifically, since the multiple resistance segments 211 of the transparent resistance structure 21 have gaps, the first insulating layer 30 is arranged in the gaps between the surfaces of the resistance segments 211 and the resistance segments 211, and the surface of the first insulating layer 30 away from the substrate 10 is ups and downs, so that each transparent electrode sublayer 411 is ups and downs with the surface of the first insulating layer 30 away from the substrate 10, the light-emitting layer 42 is ups and downs with the surface of the transparent electrode sublayer 411 away from the substrate 10, and the second electrode layer 43 is ups and downs with the surface of the light-emitting layer 42 away from the substrate 10, thereby eliminating the plasma mode loss of the flat surface of the second electrode layer 43 to a certain extent, reducing light loss, and further improving the light output rate of the light-emitting unit 40.

[0057] Optionally, the resistance of the light-transmitting resistor structure 21 is greater than or equal to 10,000 ohms and less than or equal to 10 megohms.

[0058] With this arrangement, when there are defects in the sub-light-emitting area corresponding to the transparent electrode sub-layer 411, the transparent resistor structure 21 can effectively reduce the current to avoid excessive current and excessive heat generation leading to failure of other areas.

[0059] Preferably, the resistance of the light-transmitting resistor structure 21 is greater than or equal to 20,000 ohms and less than or equal to 5 megohms. For example, the resistance of the light-transmitting resistor structure 21 can be 50,000 ohms, 1 megohm, 2 megohms, 3 megohms, 4 megohms, etc.

[0060] Optionally, the area of ​​the light-transmitting electrode sublayer 411 is greater than or equal to 30um*30um, and less than or equal to 100um*100um.

[0061] Specifically, since the light-transmitting electrode sublayers 411 are spaced apart from each other, the smaller the area of ​​the light-transmitting electrode sublayers 411, the smaller the area of ​​each sub-light-emitting area, and the smaller the light-emitting area affected by the defect. The solution of this embodiment arranges the light-transmitting resistor structure 21 and the light-emitting unit 40 in different layers, and the resistance of each light-transmitting resistor structure 21 is relatively large, so that the area of ​​the light-transmitting electrode sublayer 411 can be reduced to 30um*30um-100um*100um while meeting the resolution of the human eye, thereby reducing the light-emitting area affected by the defect, reducing the failure area, and improving the reliability of the light-emitting panel.

[0062] Exemplarily, the area of ​​the light-transmitting electrode sublayer 411 may be 30um*30um-80um*80um.

[0063] Optional, Figure 7 is a cross-sectional view of another light-emitting panel provided by an embodiment of the utility model, referring to Figure 7 , the luminous panel also includes:

[0064] The second insulating layer 50 covers the edge of the light-transmitting electrode sublayer 411 .

[0065] Specifically, the edge of the transparent electrode sublayer 411 may have defects such as burrs. Providing the second insulating layer 50 to cover the edge of the transparent electrode sublayer 411 can prevent the defects such as burrs from affecting the quality of the subsequent light-emitting layer 42 .

[0066] Optional, continue to refer to Figure 1 and Figure 2 , the anti-short circuit layer 20 further includes a plurality of preset wires 22, and the preset wires 22 are arranged on one side of the light-transmitting resistor structure 21;

[0067] The first end of each light-transmitting resistor structure 21 is electrically connected to the light-transmitting electrode sublayer 411 , and the second end of each light-transmitting resistor structure 21 is electrically connected to a preset wire 22 , and the preset wire 22 is used to transmit a light-emitting driving signal;

[0068] One of the first end and the second end of the light-transmitting resistor structure 21 is a starting end of the light-transmitting resistor structure 21 , and the other is an end of the light-transmitting resistor structure 21 .

[0069] Specifically, the preset wire 22 can be in a grid shape, or the preset wire 22 can extend in the row direction, or the preset wire 22 can extend in the column direction. The preset wire 22 is arranged between adjacent light-transmitting resistor structures 21, and the first end of the light-transmitting resistor structure 21 is electrically connected to the light-transmitting electrode sublayer 411 through a through hole, and the second end of the light-transmitting resistor structure 21 is overlapped on the preset wire 22, and the electrical connection with the preset wire 22 is directly connected. The first end of the light-transmitting resistor structure 21 can be the starting end of the light-transmitting resistor structure 21, and the second end can be the end, or the first end can be the end, and the second end can be the starting end. By setting the starting end and the end of the light-transmitting resistor structure 21 to be connected to the light-transmitting electrode sublayer 411 and the preset wire 22 respectively, the resistance of the light-transmitting resistor structure 21 connected in series with the light-transmitting electrode sublayer 411 is the largest.

[0070] Figure 8 is a schematic diagram of another light-emitting panel provided by an embodiment of the utility model, referring to Figure 8 , the light emitting panel further comprises: a driving lead 60;

[0071] The multiple transparent electrode sublayers 411 of each light-emitting unit 40 are electrically connected to the same driving lead 60 , and different light-emitting units 40 are electrically connected to different driving leads 60 ; the driving lead 60 is used to provide a light-emitting driving signal to the transparent electrode sublayer 411 .

[0072] Specifically, the second ends of the light-transmitting resistor structures 21 corresponding to the multiple light-transmitting electrode sublayers 411 of the same light-emitting unit 40 are connected to each other through a preset wire 22, the preset wire 22 is electrically connected to the driving lead 60, the driving lead 60 transmits a light-emitting driving signal to the preset wire 22, and the preset wire 22 transmits the driving signal to each light-transmitting resistor structure 21 and the light-transmitting electrode sublayer 411 corresponding to the light-transmitting resistor structure 21. The multiple light-transmitting electrode sublayers 411 of the same light-emitting unit 40 receive the light-emitting driving signal at the same time, and the sub-light-emitting areas corresponding to the multiple electrode sublayers 411 emit light at the same time.
