[0004] With the development of OLED technology, organic light-emitting diodes (OLEDs) have been applied in various fields to achieve light emission or display functions. For example, OLEDs are also used to manufacture various lighting devices. Because OLEDs have the characteristics of self-luminescence and organic light-emitting materials can be prepared on flexible substrates, OLED-based lighting devices have greater design freedom, allowing the formation of planar, rigid, foldable, and bendable light-emitting devices, while significantly reducing the thickness and weight of the light-emitting devices.

[0005] Although organic light-emitting diode (OLED)-based light-emitting devices have many advantages, current color-changing OLED devices still suffer from common disadvantages such as complex structures and large device thickness. Therefore, organic light-emitting diode panels and OLED light-emitting devices still need to be improved. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] In one aspect of the present invention, the present invention provides an organic light emitting diode panel. Figure 1 , the organic light emitting diode panel includes: a substrate 100 and a plurality of organic light emitting diodes (210A to 230B as shown in the figure). The plurality of organic light emitting diodes are located on the substrate, and the light emitting colors of the plurality of organic light emitting diodes are not exactly the same. For example, the plurality of organic light emitting diodes may include organic light emitting diodes that emit multiple colors such as red, green, blue, yellow or white. There may also be multiple organic light emitting diodes for each light emitting color. That is: the substrate 100 may have a plurality of organic light emitting diodes that emit red light, a plurality of organic light emitting diodes that emit green light, and so on. Among the plurality of organic light emitting diodes, each of the plurality of organic light emitting diodes has a first electrode, a second electrode and a light emitting layer sandwiched between the first electrode and the second electrode, the first electrode and the second electrode are connected to an external circuit, and the external circuit can make the light emitting layer emit light by applying a voltage to the first electrode and the second electrode. For example, with Figure 1Taking the structure shown in as an example, the OLED panel can include OLEDs emitting light of three different colors. The OLEDs are configured to apply the same voltage to the first electrodes of the OLEDs located on substrate 100, and the same voltage to the second electrodes of the OLEDs emitting light of the same color. Thus, the OLED panel can control the OLEDs emitting light of different colors to emit light separately, thereby controlling the color of the mixed light emitted by the panel. This panel has at least one of the advantages of a simple structure, a thin and lightweight design, and flexible and variable luminous color.

[0030] For ease of understanding, the following briefly describes the principle by which the organic light emitting diode panel according to an embodiment of the present invention can achieve the above-mentioned beneficial effects:

[0031] Current organic light-emitting diode (OLED) panels, particularly those used for lighting, often achieve multi-color emission by affixing two OLED panels with different colors, with the light-emitting panel on the light-emitting side being a transmissive panel. However, the structure of these panels is relatively complex, and the affixing of multiple panels significantly increases the overall thickness of the OLED panel. However, in an OLED panel according to an embodiment of the present invention, the first electrodes of the multiple OLEDs located on the substrate 100 can be applied with the same voltage, and the second electrodes of the OLEDs emitting the same color can be applied with the same voltage. Therefore, the OLEDs emitting the same color in the OLED panel according to an embodiment of the present invention can be turned on or off simultaneously, and the multiple OLEDs emitting different colors can be independently controlled without interfering with each other. Therefore, the OLED panel can control the color of the mixed light emitted by the OLED panel by controlling the different colors to emit light simultaneously or simultaneously, thereby achieving flexible and variable color emission. Furthermore, since the OLED panel achieves color variation by controlling the second electrodes of the OLEDs emitting different colors, there is no need to increase the thickness of the panel.

[0032] According to an embodiment of the present invention, the specific manner in which the same voltage can be applied to the first electrodes of a plurality of organic light emitting diodes and the same voltage can be applied to the second electrodes of the organic light emitting diodes with the same light emitting color is not particularly limited, and those skilled in the art can design it according to actual conditions. For example, the first electrodes of a plurality of organic light emitting diodes (such as cathodes) can be connected to the same common connection port, and the second electrodes of the organic light emitting diodes with the same light emitting color (such as anodes) can be connected to the same connection port through the setting of wiring and connection ports. Thus, the cathodes of all organic light emitting diodes on the substrate 100 can be applied with the same voltage through the same common port, while the anodes of the plurality of organic light emitting diodes with the same light emitting color are all connected to the same connection port, while the anodes of the organic light emitting diodes with different light emitting colors are connected to different connection ports. Therefore, the voltages of the anodes of the organic light emitting diodes with the same light emitting color on the substrate 100 can be simultaneously controlled through this port. For example, with Figure 1 Taking the structure shown in FIG as an example, the substrate 100 may include organic light-emitting diodes (OLEDs) emitting three colors (red, green, and blue), namely, a first organic light-emitting diode 210, a second organic light-emitting diode 220, and a third organic light-emitting diode 230. The first electrodes (not shown) of all the OLEDs can be connected to the first connection port 400, while the second electrodes (not shown) of multiple first OLEDs emitting the same color (such as 210A and 210B shown in the figure) can all be connected to the second connection port 310. Similarly, the second electrodes (not shown) of multiple second OLEDs emitting the same color (such as 220A and 220B shown in the figure) can all be connected to the third connection port 320, and the second electrodes (not shown) of multiple third OLEDs emitting the same color (such as 230A and 230B shown in the figure) can all be connected to the fourth connection port 330. It will be understood by those skilled in the art that, for current OLED panels, wiring and connection ports are also required to connect the OLEDs to external circuits (such as a voltage controller). Therefore, the above structure of the present application does not require any additional electronic components or structures to be added to the substrate 100 .

[0033] According to an embodiment of the present invention, the connection port may be located at an edge of the substrate 100. Figure 1For example, the structure shown in FIG1 is used as an example. The first connection port 400, a common port for connecting the first electrode, can be located at an edge of one side of the substrate 100. The second connection port 310, which is connected to the second electrode, can be located at the other side of the substrate 100 (for example, one edge in the longitudinal direction). The third connection port 320 and the fourth connection port 330 can be located at the same side of the substrate 100, for example, on the side opposite to the second connection port 310. This facilitates connection between the connection ports and the external circuit at the edge of the substrate 100.

[0034] According to the embodiment of the present invention, the number, light color, shape, and arrangement of the plurality of organic light emitting diodes on the substrate 100 are not particularly limited, and those skilled in the art can select them according to actual conditions. Figure 1 as well as Figure 2 , the plurality of organic light emitting diodes may all be strip-shaped, and the length of the strip may be the length of the light emitting area of ​​the organic light emitting diode panel. That is, the substrate 100 may be provided with a plurality of strip-shaped organic light emitting diodes arranged in a row. The shape of each organic light emitting diode may be Figure 1 The rectangle shown can also be Figure 2 As shown, the shape has a certain tilt angle and is similar to a parallelogram. Alternatively, multiple organic light emitting diodes can also be arranged in an array. Figure 3 , multiple organic light emitting diodes can be arranged in multiple rows and columns. The specific shape of each organic light emitting diode is not particularly limited and can be rectangular, diamond, triangular or circular, etc.

[0035] According to some specific embodiments of the present invention, the first electrodes of the plurality of organic light emitting diodes on the substrate 100 may all be connected to the same connection port, such as Figure 1 The first connection port 400 is shown in FIG. The first electrode of each organic light-emitting diode can be connected to the first connection port 400 via a wiring. Alternatively, the first electrodes of some of the multiple organic light-emitting diodes can be connected to each other via wiring, and then connected to the first connection port 400 via a wiring. Similarly, the second electrodes of multiple organic light-emitting diodes emitting the same color can also be connected to the connection port via a one-to-one corresponding wiring.

[0036] According to some embodiments of the present invention, the substrate 100 is provided with multiple organic light-emitting diodes, and each emitting color has an advantage of having multiple organic light-emitting diodes. If one organic light-emitting diode is damaged and cannot emit light, there are other organic light-emitting diodes of the same color that can still operate, so the organic light-emitting diode panel can still operate normally. The more organic light-emitting diodes there are on the substrate 100, the less impact the overall light-emitting effect of the panel will have if a single organic light-emitting diode is damaged. However, a larger number of organic light-emitting diodes also increases production costs. Therefore, the specific number of organic light-emitting diodes can be designed based on the size of the organic light-emitting diode panel and the light emission requirements.

[0037] According to an embodiment of the present invention, when the second electrodes of all organic light-emitting diodes with the same light-emitting color are connected to each other and then connected to the same connection port, since the second electrodes of all organic light-emitting diodes are equivalent to being connected in series, if one organic light-emitting diode is damaged, the series circuit will be disconnected. To prevent this situation, refer to Figure 3 Alternatively, the substrate 100 may be divided into multiple light-emitting regions, such as the first light-emitting region 1100 and the second light-emitting region 1200 shown in the figure. The second electrodes of multiple organic light-emitting diodes located in the same light-emitting region and emitting the same color are connected to the voltage controller via the same trace. This can further improve the performance of the organic light-emitting diode panel. For example, referring to Figure 3, the panel can have organic light-emitting diodes (such as the first organic light-emitting diode 210, the second organic light-emitting diode 220, the third organic light-emitting diode 230 and the fourth organic light-emitting diode 240 shown in the figure) with four luminous colors (such as red, green, blue and yellow), and the multiple organic light-emitting diodes are arranged in an array, and the organic light-emitting diodes of the same luminous color are arranged in the same column. The second electrodes of the multiple first organic light-emitting diodes 210 located in the same light-emitting area can be connected in series and then connected to the same connection port through a common first trace 11A. The first light-emitting diodes located in different light-emitting areas are connected to the same connection port through different traces. That is, the second electrodes of the multiple first organic light-emitting diodes 210A located in the first light-emitting area 1100 can be connected in series and connected through the first trace 11A, while the second electrodes of the multiple first organic light-emitting diodes 210B located in the second light-emitting area 1200 can be connected in series and connected through the first trace 11B. The first trace 11A and the first trace 11B can be connected to the same connection port. Similarly, the second wiring 12 (as shown in 12A and 12B in the figure) can connect the second electrodes of multiple second organic light-emitting diodes located in the first light-emitting area 1100 and the second light-emitting area 1200, the third wiring 13 (as shown in 13A and 13B in the figure) can connect the second electrodes of multiple third organic light-emitting diodes located in the first light-emitting area 1100 and the second light-emitting area 1200, and the fourth wiring 14 (as shown in 14A and 14B in the figure) can connect the second electrodes of multiple fourth organic light-emitting diodes located in the first light-emitting area 1100 and the second light-emitting area 1200.

[0038] Alternatively, according to an embodiment of the present invention, reference Figure 4 , the panel may also include multiple identical light-emitting units. Each light-emitting unit 200 includes multiple organic light-emitting diodes with different luminous colors. That is, a single light-emitting unit does not include organic light-emitting diodes with the same luminous color, that is, the light-emitting unit is the minimum repeating unit of the organic light-emitting diode arrangement, and the number of organic light-emitting diodes contained in each light-emitting unit, the type of luminous color, and the order of arrangement are all the same. Multiple light-emitting units are arranged in multiple rows or columns on the substrate 100, or, with reference to Figure 4 , multiple light-emitting units (such as the light-emitting units 200A, 200B, and 200C shown in the figure) are arranged in an array on the substrate 100. When multiple light-emitting units are arranged in an array on the substrate 100, two light-emitting units located in two adjacent rows (or two columns, this arrangement is not shown in the figure) are staggered by one light-emitting diode in the column direction. This helps to simplify the wiring arrangement: refer to Figure 4, between two adjacent rows of OLEDs, the second electrodes of OLEDs emitting the same color in multiple light-emitting units can be connected in series along an inclined trace. Then, using traces such as the first trace 11, the second trace 12, the third trace 13, and the fourth trace 14 shown in the figure, the second electrodes of multiple OLEDs emitting the same color can be connected together. For example, first traces 11A and 11B can be used to connect multiple OLEDs emitting the same color to the same connection port. This allows for easy control of simultaneous on / off control of multiple OLEDs emitting the same color.

[0039] Alternatively, according to an embodiment of the present invention, a wiring directly connected to the connection port can be provided on the second electrode of each organic light-emitting diode. In other words, the second electrodes and wirings are connected in a one-to-one correspondence. This prevents the failure of one of the multiple organic light-emitting diodes connected in series from causing all the other organic light-emitting diodes to fail to emit light normally.

[0040] According to an embodiment of the present invention, in order to save the area occupied by the wiring, reference Figure 5 A buffer layer may be provided between the substrate 100 and the organic light emitting diode, for example, at least two buffer layers may be provided, such as the first buffer layer 610 and the second buffer layer 620 shown in the figure. Multiple traces, such as the first trace 11A and the second trace 12A shown in the figure, may be distributed in different buffer layers and connected to the second electrode of the organic light emitting diode through a via. For example, the first trace 11A connected to the second electrode 30 of the first organic light emitting diode 210A may be located in the second buffer layer 620, while the second trace 12A connected to the second electrode 31 of the second organic light emitting diode 220A may be located in the first buffer layer 610. Thus, a double-layer or even multi-layer arrangement of multiple traces can be achieved, thereby saving the area occupied by the traces in the substrate 100. Thus, the light extraction efficiency of the organic light emitting diode panel can be further improved. At the edge of the substrate 100, the connection port (such as the second connection port 310 and the third connection port 320 shown in the figure) can be exposed by strategies such as etching the buffer layer. Since the first electrodes of multiple organic light-emitting diodes can be uniformly connected to the same connection port, a continuous common first electrode 20 can also be prepared to serve as the first electrode of multiple organic light-emitting diodes. It will be understood by those skilled in the art that the organic light-emitting diode panel may also have structures such as a pixel defining layer 250.

[0041] According to an embodiment of the present invention, the organic light emitting diode panel may further include a scattering film 500. The scattering film 500 is located on the light-emitting side of the organic light emitting diode panel and can scatter the light emitted by the multiple organic light emitting diodes before emitting from the organic light emitting diode panel. The scattering film 500 can be a scattering film commonly used in conventional lighting equipment and can have a low transparency and a large roughness. This achieves a light mixing effect, allowing the light emitted by the multiple organic light emitting diodes to be mixed and emitted, preventing the light-emitting boundaries of the multiple organic light emitting diodes from being visible to the user, thereby further improving the performance of the organic light emitting diode panel. Since the scattering film 500 usually has a large roughness, in order to improve the bonding between other structures and the substrate 100 and ensure that subsequent processes can proceed smoothly, a planarization layer 700 can also be provided between the scattering film 500 and the organic light emitting diodes.

[0042] In another aspect of the present invention, an OLED light-emitting device is provided. According to an embodiment of the present invention, the OLED light-emitting device includes: a housing and the organic light-emitting diode panel described above. The housing may include a frame and a transparent lampshade, the frame and the lampshade defining a storage space, the organic light-emitting diode panel being accommodated within the storage space, and the light-emitting side of the organic light-emitting diode panel being arranged toward the lampshade. The OLED light-emitting device has all the features and advantages of the organic light-emitting diode panel described above, which will not be elaborated here. In general, the OLED light-emitting device has at least one of the advantages of a simple structure, a light and thin volume, and flexible and variable light-emitting color.
