[0071] Details
[0072] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The embodiments can be implemented in a variety of different forms. A person skilled in the art can easily understand that the methods and contents can be transformed into a variety of forms without departing from the purpose and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited to the contents described in the following embodiments. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other in any manner.
[0073] In the drawings, the size of one or more components, layer thicknesses, or regions may be exaggerated for clarity. Therefore, one embodiment of the present disclosure is not necessarily limited to these dimensions, and the shapes and sizes of one or more components in the drawings do not reflect true proportions. Furthermore, the drawings schematically illustrate idealized examples, and one embodiment of the present disclosure is not limited to the shapes or values shown in the drawings.
[0074] In this specification, ordinal numbers such as "first," "second," and "third" are provided to avoid confusion among constituent elements, and are not intended to limit the number. "Multiple" in this disclosure means two or more.
[0075] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the direction in which each constituent element is described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced according to the circumstances.
[0076] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; they can refer to mechanical connections or connections; they can refer to direct connections, indirect connections through intermediaries, or internal communication between two components. Those skilled in the art will understand the meaning of these terms in this disclosure based on the circumstances.
[0077] In this specification, a transistor refers to a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between a drain electrode (drain electrode terminal, drain region, or drain electrode) and a source electrode (source electrode terminal, source region, or source electrode), and current can flow through the drain electrode, the channel region, and the source electrode. In this specification, the channel region refers to the region through which current primarily flows.
[0078] In this specification, the first electrode can be a drain electrode and the second electrode can be a source electrode, or vice versa. The functions of "source electrode" and "drain electrode" may be interchanged when using transistors with opposite polarity or when the direction of current changes during circuit operation. Therefore, in this specification, "source electrode" and "drain electrode" may be interchanged.
[0079] In this specification, "connected" includes components connected together via an element having some electrical function. There are no particular limitations on the "element having some electrical function" as long as it enables transmission of electrical signals between the connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other components with various functions.
[0080] In this specification, "parallel" refers to a state where the angle formed by two straight lines is greater than -10° and less than 10°, and thus also includes a state where the angle is greater than -5° and less than 5°. Furthermore, "perpendicular" refers to a state where the angle formed by two straight lines is greater than 80° and less than 100°, and thus also includes a state where the angle is greater than 85° and less than 95°.
[0081] The terms “approximately” and “substantially” in the present disclosure do not strictly define the limits and allow for errors within the range of process and measurement errors.
[0082] In this specification, "A extends along direction B" means that A may include a main portion and a secondary portion connected to the main portion, the main portion being a line, line segment, or strip, extending along direction B, and the length of the main portion extending along direction B being greater than the length of the secondary portion extending along other directions. Throughout this specification, "A extends along direction B" means "the main portion of A extends along direction B."
[0083] As used herein, "A and B are in the same layer" means that A and B are formed simultaneously through the same patterning process. "Same layer" does not always mean that the thickness or height of the layer is the same in a cross-sectional view. "The orthographic projection of A includes the orthographic projection of B" means that the orthographic projection of B falls within the orthographic projection of A, or that the orthographic projection of A covers the orthographic projection of B.
[0084] With the development of display technology, increasing the screen-to-body ratio and reducing the size of the border is an important direction of improvement. Current display panels are usually equipped with a multiplexing circuit (MUX) to reduce the number of data lines, thereby reducing the space required for the data lead lines in the border area to reduce the border size. Usually, the multiplexing circuit can adopt a 1:6 design (that is, a single multiplexing unit provides data signals to multiple data lines under the control of six multiplexing control lines), and the border space of the display panel (such as the display panel of a wearable product) is limited, and the layout form of the multiplexing circuit is relatively fixed. However, for display products with higher refresh rate requirements, the conventional multiplexing circuit using a 1:6 design will affect the display effect of display products with high refresh rate requirements.
[0085] This embodiment provides a display panel and a display device, which can arrange a multiplexing circuit that meets the high refresh rate requirements of the display product on a display panel with limited frame space, thereby realizing a layout design of a multiplexing circuit suitable for high refresh rate requirements.
[0086] This embodiment provides a display panel comprising: a substrate, a plurality of sub-pixels, a plurality of data lines, and a multiplexing circuit. The substrate includes a display area and a first frame area located on at least one side of the display area. The plurality of sub-pixels and the plurality of data lines are located in the display area. The plurality of data lines are connected to the plurality of sub-pixels and configured to provide data signals to the plurality of sub-pixels. The multiplexing circuit is located in the first frame area and includes a plurality of multiplexing units. At least one of the plurality of multiplexing units includes a plurality of multiplexing transistors. The at least one multiplexing unit is electrically connected to a multiplexing data line, a plurality of multiplexing control lines, and a plurality of data lines, and is configured to provide the data signals transmitted by the multiplexing data line to the plurality of data lines under the control of the plurality of multiplexing control lines. The multiplexing transistors of the plurality of multiplexing units are arranged in multiple rows and columns. A row of multiplexing transistors includes a plurality of multiplexing transistors arranged along a first direction, and a column of multiplexing transistors includes a plurality of multiplexing transistors arranged along a second direction. The first direction and the second direction intersect. For example, the first direction may be perpendicular to the second direction.
[0087] The display panel provided in this embodiment arranges the multiplexing transistors of the multiplexing circuit in an array, so that the multiplexing circuit suitable for high refresh rate requirements can be arranged in a frame area with limited space.
[0088] In some exemplary embodiments, a column of multiplexing transistors may include multiplexing transistors connected to the same multiplexing control line. This example arranges multiple multiplexing transistors connected to the same multiplexing control line in a column, thereby reducing the occupied space of the multiplexing circuit in the first direction.
[0089] In some exemplary embodiments, a column of multiplexing transistors may include multiple multiplexing transistors connected to the same multiplexing data line. This example facilitates reducing the space occupied by the multiplexing circuit in the first direction by arranging multiple multiplexing transistors connected to the same multiplexing data line in a column. For example, at least one multiplexing unit may include three multiplexing transistors, each electrically connected to different multiplexing control lines and to the same multiplexing data line. The three multiplexing transistors of the at least one multiplexing unit may be arranged in the same column.
[0090] In some exemplary embodiments, the multiplexing transistors of the multiplexing circuit may be arranged in three rows. This embodiment is not limited to this. In other examples, the multiplexing transistors of the multiplexing circuit may be arranged in two rows or more than three rows, such as six rows.
[0091] In some exemplary embodiments, at least one multiplexing unit includes two multiplexing transistors, the two multiplexing transistors being electrically connected to different multiplexing control lines and electrically connected to the same multiplexing data line. The two multiplexing transistors of the multiplexing unit can be arranged in the same row. In some examples, the multiplexing units can include at least: a plurality of first multiplexing units, a plurality of second multiplexing units, and a plurality of third multiplexing units. The multiplexing transistors of the plurality of first multiplexing units can be arranged in a first row, the multiplexing transistors of the plurality of second multiplexing units can be arranged in a second row, and the multiplexing transistors of the plurality of third multiplexing units can be arranged in a third row. The multiplexing transistors in the first, second, and third multiplexing units that are electrically connected to the same multiplexing control line can be arranged in the same column. For example, the gates of the plurality of multiplexing transistors in a column of multiplexing transistors can be interconnected as an integrated structure. The arrangement of this example helps reduce the space occupied by the multiplexing circuit in the first direction.
[0092] In some exemplary embodiments, the plurality of sub-pixels may include: a first sub-pixel emitting a first color light, a second sub-pixel emitting a second color light, and a third sub-pixel emitting a third color light. The first multiplexing unit may be configured to provide data signals to the plurality of first sub-pixels, the second multiplexing unit may be configured to provide data signals to the plurality of second sub-pixels, and the third multiplexing unit may be configured to provide data signals to the plurality of third sub-pixels. The multiplexing circuit of this example may adopt a 1:2 design to provide data signals to the plurality of sub-pixels, wherein a single multiplexing unit may provide data signals to adjacent sub-pixels of the same color, which not only reduces the load of the data signal but also facilitates achieving high refresh rate requirements.
[0093] The solution of this embodiment is illustrated below through multiple examples.
[0094] Figure 1 is a schematic diagram of a display panel according to at least one embodiment of the present disclosure. In some examples, as shown in Figure 1 , the display panel may include: a display area AA, a first border area B1 located on one side of the display area AA, and a second border area B2 located on the remaining sides of the display area AA. The first border area B1 may be connected to the second border area B2. For example, the first border area B1 may be the bottom border of the display panel, and the second border area B2 may include the remaining border area of the display panel excluding the bottom border.
[0095] In some examples, as shown in FIG1 , the display area AA may be a flat area including a plurality of sub-pixels PX constituting a pixel array, and the plurality of sub-pixels PX may be configured to display a dynamic image or a still image. The display area AA may be referred to as an active area. In some examples, the display area AA may be circular or elliptical. However, this embodiment is not limited thereto. For example, the display area may be other shapes such as a rectangle. In some examples, the display panel may be a flexible panel, and thus the display panel may be deformable, such as being curled, bent, folded, or rolled up.
[0096] In some examples, as shown in FIG1 , the display area AA may include: a display structure layer provided on a substrate, or may include a display structure layer and a touch structure layer provided in sequence on a substrate. For example, the display panel may integrate a touch structure to form a structure in which the touch structure is on a thin film package (Touch on Thin Film Encapsulation, referred to as Touch on TFE). The Touch on TFE structure mainly includes a Flexible Multi-Layer On Cell (FMLOC) structure and a Flexible Single-Layer On Cell (FSLOC) structure. The FMLOC structure is based on the working principle of mutual capacitance detection. Generally, two layers of metal are used to form the driving (Tx) electrode and the sensing (Rx) electrode. The driving chip (IC) realizes the touch action by detecting the mutual capacitance between the driving electrode and the sensing electrode. The FSLOC structure is based on the working principle of self-capacitance (or voltage) detection. Generally, a single layer of metal is used to form the touch electrode. The integrated circuit realizes the touch action by detecting the self-capacitance (or voltage) of the touch electrode.
[0097] In some examples, the display structure layer may include a plurality of sub-pixels PX, a plurality of gate lines GL, and a plurality of data lines DL. The plurality of gate lines GL may extend along a first direction X, and the plurality of data lines DL may extend along a second direction Y. The orthographic projections of the plurality of gate lines GL and the plurality of data lines DL on the substrate may intersect to form a plurality of sub-pixel regions. One sub-pixel PX may be arranged in one sub-pixel region. The plurality of data lines DL may be electrically connected to the plurality of sub-pixels PX, and the plurality of data lines DL may be configured to provide data signals to the plurality of sub-pixels PX. The plurality of gate lines GL may be electrically connected to the plurality of sub-pixels PX, and the plurality of gate lines GL may be configured to provide gate drive signals to the plurality of sub-pixels PX. For example, the gate drive signal may include a scan signal, or may include a scan signal and a light-emitting control signal, or may include a scan signal, a reset control signal, and a light-emitting control signal.
[0098] In some examples, as shown in FIG1 , the first direction X may be an extending direction (e.g., a row direction) of the gate lines GL in the display area AA, and the second direction Y may be an extending direction (e.g., a column direction) of the data lines DL in the display area AA. The first direction X and the second direction Y may intersect each other, for example, may be perpendicular to each other.
[0099] Figure 2 is a schematic diagram of the planar structure of a display panel of at least one embodiment of the present disclosure. In some examples, as shown in Figure 2, a pixel unit P in the display area AA may include three sub-pixels, and the three sub-pixels may be a first sub-pixel P1 emitting a first color light (e.g., red light), a second sub-pixel P2 emitting a second color light (e.g., green light), and a third sub-pixel P3 emitting a third color light (e.g., blue light). However, this embodiment is not limited to this. In some examples, a pixel unit may include four sub-pixels, and the four sub-pixels may be a sub-pixel emitting red light, a sub-pixel emitting green light, a sub-pixel emitting blue light, and a sub-pixel emitting white light. For another example, a pixel unit may include four sub-pixels, and the four sub-pixels may include a sub-pixel emitting red light, a sub-pixel emitting blue light, and two sub-pixels emitting green light.
[0100] In some examples, the shape of the sub-pixels can be a rectangle, a diamond, a pentagon, or a hexagon. When a pixel unit includes three sub-pixels, the three sub-pixels can be arranged horizontally, vertically, or in a triangular pattern. When a pixel unit includes four sub-pixels, the four sub-pixels can be arranged horizontally, vertically, or in a square pattern. However, this embodiment is not limited to this.
[0101] In some examples, a sub-pixel may include: a pixel circuit and a light-emitting element electrically connected to the pixel circuit. The pixel circuit may include multiple transistors and at least one capacitor. For example, the pixel circuit may be a 3T1C, 4T1C, 5T1C, 5T2C, 6T1C, 7T1C or 8T1C structure. In the above circuit structure, T refers to a thin film transistor, C refers to a capacitor, the number before T represents the number of thin film transistors in the circuit, and the number before C represents the number of capacitors in the circuit. In some examples, the multiple transistors in the pixel circuit may be P-type transistors, or may be N-type transistors. Using transistors of the same type in the pixel circuit can simplify the process flow, reduce the process difficulty of the display panel, and improve the product yield. In other examples, the multiple transistors in the pixel circuit may include P-type transistors and N-type transistors.
[0102] In some examples, multiple transistors in the pixel circuit may use low-temperature polysilicon thin-film transistors, or may use oxide thin-film transistors, or may use low-temperature polysilicon thin-film transistors and oxide thin-film transistors. The active layer of the low-temperature polysilicon thin-film transistor uses low-temperature polysilicon (LTPS), and the active layer of the oxide thin-film transistor uses oxide semiconductor (Oxide). Low-temperature polysilicon thin-film transistors have the advantages of high mobility and fast charging, and oxide thin-film transistors have the advantages of low leakage current. Integrating low-temperature polysilicon thin-film transistors and oxide thin-film transistors on a display panel, that is, an LTPS+Oxide (LTPO for short) display panel, can take advantage of the advantages of both, achieve low-frequency driving, reduce power consumption, and improve display quality.

However, this embodiment is not limited to this. In other examples, a buffer layer may be provided on the side of the semiconductor layer near the substrate. The buffer layer can prevent harmful substances in the substrate from invading the interior of the display panel and can also improve the adhesion of the film layer in the display panel to the substrate. In other examples, the fourth insulating layer may be omitted between the third and fourth conductive layers, and only the fifth insulating layer may be provided. Alternatively, the fifth insulating layer may be omitted between the third and fourth conductive layers, and only the fourth insulating layer may be provided.

The third insulating layer 103 may have multiple vias (e.g., including a first pixel via and a second pixel via) in the display area. The third insulating layer 103, the second insulating layer 102, and the first insulating layer 101 within the first pixel via can be removed, exposing at least a portion of the surface of the first region 2101 of the active layer 210. The third insulating layer 103, the second insulating layer 102, and the first insulating layer 101 within the second pixel via can be removed, exposing at least a portion of the surface of the second region 2102 of the active layer 210.

For example, each light-emitting element may include a stacked first electrode 131, an organic light-emitting layer 132, and a second electrode 133. The first electrode 131 of the light-emitting element may be an anode. The first electrode 131 may be disposed on the sixth insulating layer 106 and electrically connected to the anode connection electrode 231 through a third pixel via provided in the sixth insulating layer 106. The pixel definition layer 134 is disposed on the first electrode 131 and the second planar layer 106.

At least a portion of the organic light-emitting layer 132 may be disposed within a pixel opening and connected to the corresponding first electrode 131. The second electrode 133 may be disposed on and connected to the organic light-emitting layer 132. Driven by the first electrode 131 and the second electrode 133, the organic light-emitting layer 132 may emit light of a corresponding color.
[0109] In some examples, the organic light-emitting layer 132 of the light-emitting element may include an emitting layer (EML), and one or more of the following film layers: a hole injection layer (HIL), a hole transport layer (HTL), a hole blocking layer (HBL), an electron blocking layer (EBL), an electron injection layer (EIL), and an electron transport layer (ETL). Driven by the voltage of the first electrode 131 and the second electrode 133, the light-emitting properties of the organic material can be utilized to emit light according to the required grayscale.
[0110] In some examples, the light-emitting layers of light-emitting elements emitting light of different colors may be different. For example, a red light-emitting element includes a red light-emitting layer, a green light-emitting element includes a green light-emitting layer, and a blue light-emitting element includes a blue light-emitting layer. In order to reduce the process difficulty and improve the yield, the hole injection layer and the hole transport layer on one side of the light-emitting layer may adopt a common layer, and the electron injection layer and the electron transport layer on the other side of the light-emitting layer may adopt a common layer. In some examples, any one or more layers of the hole injection layer, the hole transport layer, the electron injection layer and the electron transport layer can be made by a single process (a single evaporation process or a single inkjet printing process), and isolation is achieved by means of a surface step difference of the formed film layer or by surface treatment. For example, any one or more layers of the hole injection layer, the hole transport layer, the electron injection layer and the electron transport layer corresponding to adjacent sub-pixels may be isolated. In some examples, the organic light-emitting layer can be formed by evaporation using a fine metal mask (FMM) or an open mask (Open Mask), or by inkjet technology.

The second encapsulation layer 142 may be disposed between the first encapsulation layer 141 and the third encapsulation layer 143 to prevent external moisture from entering the light-emitting element. However, this embodiment is not limited to this. For example, the encapsulation structure layer may have a five-layer stacked structure of inorganic / organic / inorganic / organic / inorganic.

When the touch unit includes multiple touch electrodes, the multiple touch electrodes may be arranged at intervals, and adjacent touch electrodes may be connected to each other through connecting portions. The touch electrodes and the connecting portions may be in the same layer structure. In some examples, the touch electrode may have a rhombus shape, for example, a regular rhombus, a horizontally long rhombus, or a vertically long rhombus. However, this embodiment is not limited to this. In some examples, the touch electrode may have any one or more of a triangle, a square, a trapezoid, a parallelogram, a pentagon, a hexagon, and other polygons.

The multiple display lead lines may include a plurality of data lead lines and a plurality of drive lead lines. The multiple data lead lines may be electrically connected to the multiple data lines of the display area AA, for example, in a one-to-one electrical connection. Multiple drive lead lines can extend to the second border area B2 and be electrically connected to the gate drive circuit in the second border area B2. They can be configured to provide control signals to the gate drive circuit. For example, the control signals may include a start signal, a clock signal, etc. Multiple touch lead lines can extend from the second border area B2 to the first fan-out area B11 and can be located on the side of the multiple display lead lines away from the substrate.
[0114] In some examples, as shown in Figure 1, the bending area B12 can be connected to the first fan-out area B11 and the second fan-out area B13 and located on the side of the first fan-out area B11 away from the display area AA.

The bending area B12 can be provided with multiple bending connection lines, such as multiple data bending connection lines, multiple touch bending connection lines, etc. For example, the multiple bending connection lines within the bending area B12 can be provided on the same layer, such as all located in the fourth conductive layer or the third conductive layer.
[0115] In some examples, as shown in FIG1 , the second fan-out region B13 may be located on a side of the bending region B12 away from the display region AA. For example, a plurality of test circuits may be provided in the second fan-out region B13.
[0116] In some examples, as shown in FIG1 , the first signal access area B14 may be located on a side of the second fan-out area B13 away from the display area AA. The first signal access area B14 may also be referred to as a driver chip setting area. The first signal access area B14 may be provided with a plurality of first contact pads (Bumps), which may be configured to be bound and connected to at least one driver chip (IC, Integrated Circuit). The driver chip may be configured to generate a drive signal required to drive the sub-pixel, for example, a data signal.
[0117] In some examples, as shown in Figure 1, the second signal access area B15 can be located on a side of the first signal access area B14 away from the display area AA.

The plurality of second contact pads can be configured to be bound and connected to at least one circuit board (e.g., a flexible printed circuit board (FPC)). For example, an external circuit board can be configured to generate a touch signal provided to the touch structure and receive a touch sensing signal.
[0118] In some examples, a multiplexing circuit may also be provided in the first fan-out area B11. For example, the multiplexing circuit may be adjacent to the bend area B12. The multiplexing circuit may be electrically connected to the multiple data lines in the display area AA via multiple data lead lines to be configured to transmit data signals to the multiple data lines. The multiplexing circuit may also be electrically connected to the multiple multiplexed data lines to be configured to receive data signals transmitted by a driver chip provided in the first signal access area B14. The multiplexed data lines may be electrically connected to the multiple data bend connection lines in the bend area. The second fan-out area may also be provided with multiple multiplexed data lead lines, which are electrically connected to the multiple data bend connection lines. The multiplexed data lead lines may be electrically connected to multiple first contact pads in the first signal access area B14 that transmit data signals. In some examples, the data signals provided by the driver chip may be sequentially transmitted to the data lines in the display area via the multiplexed data lead lines, the data bend connection lines, the multiplexed data lines, the multiplexing circuit, and the data lead lines. The multiplexing circuit can provide data signals transmitted by M multiplexed data lines to N data lines, where M and N are both integers, and M is less than N. The multiplexing circuit can reduce the number of data signal transmission lines, which helps reduce the size of the frame. It can also support situations where the driver chip has fewer data signal lines, allowing the driver chip to support providing data signals to all data lines in the display area.
[0119] FIG4 is an equivalent circuit diagram of a multiplexing circuit according to at least one embodiment of the present disclosure. In some examples, as shown in FIG4 , the multiplexing circuit 30 may include multiple multiplexing units. A multiplexing unit may be configured to provide a data signal provided by a multiplexed data line to multiple data lines (e.g., two data lines).
[0120] In some examples, as shown in FIG4 , a multiplexing unit can be electrically connected to two multiplexing control lines (e.g., a first multiplexing control line 51 and a second multiplexing control line 52), a multiplexing data line, and multiple data lines (e.g., two data lines). Each multiplexing unit can include two multiplexing transistors. The two data lines connected to a multiplexing unit can be electrically connected to sub-pixels that emit light of the same color. The connection method of the multiplexing unit in this example can effectively reduce the load of the data signal.
[0121] FIG4 illustrates six multiplexing units of multiplexing circuit 30 as an example. Three multiplexing units may form a group. Each group of multiplexing units is connected in a similar manner, and the following description uses a group of multiplexing units as an example. In some examples, as shown in FIG4 , a group of multiplexing units may include a first multiplexing unit 31, a second multiplexing unit 32, and a third multiplexing unit 33.
[0122] In some examples, as shown in FIG4 , the first multiplexing unit 31 may include a first multiplexing transistor T1 and a second multiplexing transistor T2. The gate of the first multiplexing transistor T1 is electrically connected to the first multiplexing control line 51, the first electrode of the first multiplexing transistor T1 is electrically connected to the first multiplexing data line 41, and the second electrode of the first multiplexing transistor T1 is electrically connected to the first data line 61.

[0123] In some examples, as shown in FIG4 , the second multiplexing unit 32 may include a third multiplexing transistor T3 and a fourth multiplexing transistor T4. The gate of the third multiplexing transistor T3 is electrically connected to the first multiplexing control line 51, the first electrode of the third multiplexing transistor T3 is electrically connected to the second multiplexing data line 42, and the second electrode of the third multiplexing transistor T3 is electrically connected to the second data line 62.

[0126] In this example, the data signals received by adjacent monochrome sub-pixels are controlled by the same multiplexing unit, which can effectively reduce the load of the data signal and make the data voltage difference corresponding to the same color sub-pixels in the same row of sub-pixels smaller, thereby reducing power consumption; moreover, the multiplexing circuit adopts a 1:2 design (that is, a design in which one multiplexed data line provides data signals to two data lines), which can not only effectively reduce the load of the data signal, but also is conducive to achieving high refresh rate requirements.

[0187] The phrase "A and B are arranged in the same layer" or "A and B are of the same layer structure" in the present disclosure means that A and B are formed simultaneously by the same patterning process. The phrase "A and B are of different layer structures" means that A and B are formed separately by two patterning processes. The "thickness" of the film layer is the dimension of the film layer in the direction perpendicular to the display panel. In the exemplary embodiments of the present disclosure, "the orthographic projection of B is within the range of the orthographic projection of A" or "the orthographic projection of A includes the orthographic projection of B" means that the boundary of the orthographic projection of B falls within the boundary of the orthographic projection of A, or the boundary of the orthographic projection of A overlaps with the boundary of the orthographic projection of B.

In some examples, as shown in FIG25 , multiplexing circuit 30 may include multiple multiplexing units 34. One multiplexing unit 34 may be configured to provide a data signal provided by one multiplexed data line to multiple data lines (e.g., three data lines).
[0249] In some examples, as shown in FIG25 , a multiplexing unit 34 can be electrically connected to three multiplexing control lines (e.g., including a third multiplexing control line 53, a fourth multiplexing control line 54, and a fifth multiplexing control line 55), a multiplexing data line, and multiple data lines (e.g., three data lines). Each multiplexing unit 34 can include three multiplexing transistors. The three data lines connected to a multiplexing unit 34 can be electrically connected to sub-pixels that emit light of different colors. The connection method of the multiplexing unit in this example can effectively save the required data signals.

The third data line can be electrically connected to a column of third subpixels B1. The column of first subpixels R1, the column of second subpixels G1, and the column of third subpixels B1 can be configured to emit light of different colors. For example, the column of first subpixels R1 can emit red light, the column of second subpixels G1 can emit green light, and the column of third subpixels B1 can emit blue light.
[0251] In this example, the data signals received by three adjacent sub-pixels emitting light of different colors can be controlled by the same multiplexing unit. A 1:3 design (i.e., a design in which one multiplexed data line provides data signals to three data lines) can be used to achieve high refresh rate requirements.
