[0084] Details

[0085] 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 method and content can be transformed into other 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.

[0086] 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.

[0087] 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.

[0088] 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 is not intended to 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 limitations on the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the orientation of the constituent elements being described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced depending on the circumstances.

[0089] In this specification, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "coupled" should be interpreted 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 meanings of these terms in this disclosure based on the specific circumstances.

[0090] In this specification, "electrically 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 multiple functions.

[0091] In this specification, a transistor refers to a device that includes at least three terminals: a gate, a drain, and a source. A transistor has a channel region between the drain (drain electrode terminal, drain region, or drain electrode) and the source (source electrode terminal, source region, or source electrode), and current can flow through the drain, channel region, and source. In this specification, the channel region refers to the region through which current primarily flows.

[0092] In this specification, the first electrode can be referred to as the drain and the second electrode as the source, or vice versa. The functions of "source" and "drain" are sometimes interchanged when using transistors with opposite polarity or when the direction of current changes during circuit operation. Therefore, in this specification, the terms "source" and "drain" can be interchanged. Furthermore, the gate electrode can also be referred to as the control electrode.

[0093] 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°.

[0094] In this specification, circles, ellipses, triangles, rectangles, trapezoids, pentagons or hexagons are not in the strict sense, but may be approximate circles, approximate ellipses, approximate triangles, approximate rectangles, approximate trapezoids, approximate pentagons or approximate hexagons, etc. There may be some small deformations caused by tolerances, such as chamfers, arc edges and deformations.

[0095] The term "light transmittance" in this disclosure refers to the ability of light to pass through a medium, and is the percentage of the luminous flux passing through a transparent or translucent body to the incident luminous flux.

[0096] In this disclosure, the terms "approximately" and "substantially" are used without strict boundaries, allowing for process and measurement errors. In this disclosure, "same" can include both identical and substantially the same. "Substantially the same" means that the values ​​differ by less than 10%.

[0097] In this disclosure, "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. In this disclosure, "A extends along direction B" means "the main portion of A extends along direction B."

[0098] With the continuous development of display technology, cameras are usually installed on display devices to meet the needs of shooting or face recognition. In order to maximize the screen-to-body ratio, technologies such as bangs screen, water drop screen, and hollowing out in the screen have appeared one after another. These technologies are achieved by making holes in part of the display area and placing a camera below the hole area to reduce the area occupied by the camera, thereby increasing the screen-to-body ratio. However, the above technologies require digging out part of the display area, which will cause part of the display image to be unable to be displayed, and the screen-to-body ratio cannot be further increased. In order to avoid punching holes in the display area and to make a true full screen possible while ensuring the practicality of the display substrate, the pixel circuit external method or the pixel circuit internal method is usually adopted in the camera area under the screen.

[0099] The external pixel circuit method involves placing the pixel circuits connected to the light-emitting elements in the under-screen camera area within the normal display area. By separating the light-emitting elements and pixel circuits, the light transmittance of the under-screen camera area is improved. Since the under-screen camera area lacks pixel circuits, it lacks any light-shielding layers other than the anodes of the light-emitting elements, resulting in higher light transmittance. However, with this method, the pixel circuits and light-emitting elements must be electrically connected via conductive wires. Limited by the space available for these wires, the size (e.g., aperture) of the under-screen camera area of ​​the display substrate using the external pixel circuit method is limited. Furthermore, increasing the aperture of the under-screen camera area typically requires additional masking processes for the conductive wires, increasing costs. Furthermore, the conductive wires are typically made of transparent conductive materials, such as indium tin oxide (ITO). Due to the high sheet resistance of ITO, longer conductive wires carry a heavy load, which can easily affect the brightness of the light-emitting elements in the under-screen camera area, reducing the brightness of the under-screen camera area and causing display artifacts, such as vertical mura.

[0100] The built-in pixel circuit method involves installing a light-emitting element and the pixel circuit connected to it in the under-screen camera area. Compared to the external pixel circuit method, the built-in method eliminates the need for long conductive wires to connect the pixel circuit and light-emitting element in the under-screen camera area, thus avoiding display issues in the under-screen camera area caused by these wires. Furthermore, the built-in method has no size restrictions on the under-screen camera area and can support large-aperture under-screen camera areas. To improve the light transmittance of the under-screen camera area, the pixel density of the under-screen camera area is significantly different from that of the normal display area, which can easily lead to display differences between the normal display area and the under-screen camera area.

[0101] This embodiment provides a display substrate and a display device, which can increase the pixel density of the under-screen camera area while ensuring the light transmittance of the under-screen camera area, thereby achieving high pixel density (PPI, Pixels Per Inch) display.

[0102] This embodiment provides a display substrate, comprising: a first display area, the first display area comprising a plurality of island areas and a transmissive area located between adjacent island areas. The transmissive area has a greater light transmittance than the island areas. The transmissive area includes at least one first light-emitting element disposed on a substrate, and the island area includes at least one first pixel circuit disposed on the substrate. The at least one first pixel circuit is electrically connected to at least one first light-emitting element in an adjacent transmissive area, and the distance between the first pixel circuit and the orthographic projection of the connected first light-emitting element on the substrate is greater than zero. In other words, the orthographic projection of the first pixel circuit on the substrate does not overlap with the orthographic projection of the connected first light-emitting element on the substrate.

[0103] In some examples, the first pixel circuit and the first light-emitting element can be connected in a one-drive-one or one-drive-many manner. In this embodiment, one-drive-one means that the pixel circuit and the light-emitting element can be connected one-to-one, and one pixel circuit is configured to drive one connected light-emitting element. One-drive-many means that one pixel circuit is electrically connected to multiple light-emitting elements, and one pixel circuit is configured to drive multiple connected light-emitting elements. For example, one-drive-many can be one-drive-two (i.e., one pixel circuit is connected to two light-emitting elements), one-drive-three (i.e., one pixel circuit is connected to three light-emitting elements), one-drive-four (i.e., one pixel circuit is connected to four light-emitting elements), or one-drive-five (i.e., one pixel circuit is connected to five light-emitting elements). In some examples, the first pixel circuit and the first light-emitting element can be connected in a one-drive-many manner; for example, a first pixel circuit can be electrically connected to multiple first light-emitting elements that emit light of the same color. This embodiment is not limited to this.

[0104] The display substrate provided in this embodiment, by arranging a first light-emitting element in the transmission area between the island areas and arranging a first pixel circuit driving the first light-emitting element in the island area, can increase the pixel density of the first display area while ensuring the light transmittance of the first display area, thereby supporting high PPI display in the first display area.

[0105] In some exemplary embodiments, the first pixel circuit in the island region may be electrically connected to multiple first light-emitting elements in the adjacent transmissive region that emit light of the same color. In this example, the first pixel circuit and the first light-emitting element may be connected using a one-drive-many configuration, which reduces the number of first pixel circuits and helps reduce the circuit layout space required in the first display region.

[0106] In some exemplary embodiments, the transmissive area may include multiple first light-emitting elements emitting light of different colors. The first light-emitting elements emitting light of different colors within the transmissive area may be located on different insulating layers, while the first light-emitting elements emitting light of the same color within the transmissive area may be located on the same insulating layer. In this example, multiple first light-emitting elements may be located on different insulating layers depending on the color of the light emitted by the first light-emitting element, thereby ensuring the light transmittance and display quality of the first display area.

[0107] In some exemplary embodiments, the transmissive region may include multiple first light-emitting elements emitting light of different colors, and the multiple first light-emitting elements in the transmissive region may be located on the same insulating layer. In this example, the multiple first light-emitting elements in the transmissive region being located on the same insulating layer can ensure the flatness of the anodes of the multiple first light-emitting elements, which is beneficial for maintaining a good display effect.

[0108] In some exemplary embodiments, a first pixel circuit in an island region is connected to at least one first light-emitting element in an adjacent transmissive region via at least one connecting line. The at least one connecting line may be made of a metal material or a transparent conductive material. In some examples, the first pixel circuit may be connected to a first light-emitting element in an adjacent transmissive region via a single connecting line, or may be connected to multiple first light-emitting elements in an adjacent transmissive region via a single connecting line; or may be connected to a first light-emitting element in an adjacent transmissive region via multiple connecting lines; or may be connected to multiple first light-emitting elements in an adjacent transmissive region via multiple connecting lines. For example, the first pixel circuit may be connected to multiple first light-emitting elements in an adjacent transmissive region via multiple connecting lines. The multiple connecting lines may include a first connecting line and a second connecting line. The first pixel circuit may be connected to a first light-emitting element in an adjacent transmissive region via the first connecting line, and multiple first light-emitting elements in adjacent transmissive regions connected to the same first pixel circuit may be connected via the second connecting line. For example, the first connecting line and the second connecting line may be an integral structure connected to each other. This embodiment is not limited to this. In other examples, the first connecting line and the second connecting line may be located in different film layers, or may be made of different materials.

[0109] In some exemplary embodiments, the display substrate may include a shielding layer located in the island region. The shielding layer may be located on the side of the first pixel circuit close to the substrate. The orthographic projection of the shielding layer on the substrate may cover the orthographic projection of the active layer of at least one transistor of the first pixel circuit on the substrate. At least one connecting line and the shielding layer may be co-layered. In this example, by arranging at least one connecting line in the same layer as the shielding layer, the number of preparation steps can be reduced, which is beneficial for cost savings. Furthermore, the use of metal materials for the connecting line can reduce resistance, thereby facilitating the effectiveness of signal transmission by the connecting line.

[0110] In some exemplary embodiments, the anode of the first light-emitting element may include: a plurality of anode sublayers, at least one connecting wire and one of the anode sublayers being in the same layer structure. For example, a plurality of connecting wires may be in the same layer structure as the same anode sublayer, or a portion of the connecting wires may be in the same layer structure as one anode sublayer, and another portion of the connecting wires may be in the same layer structure as another anode sublayer. In some examples, the anode of the first light-emitting element may include: a first anode sublayer, a second anode sublayer, and a third anode sublayer; the first anode sublayer and the third anode sublayer may be made of transparent conductive materials, such as indium tin oxide (ITO); the second anode sublayer may be made of a metal material, such as silver (Ag). For example, a plurality of connecting wires may be in the same layer structure as the first anode sublayer. This example reduces the preparation steps by setting the connecting wires to be in the same layer structure as one of the anode sublayers, which is beneficial to saving costs. Moreover, the connecting wires are made of transparent conductive materials, which is beneficial to ensuring the light transmittance of the first display area.

[0111] In some exemplary embodiments, the display substrate may further include: at least one transparent conductive layer positioned between the first pixel circuit and the first light-emitting element; and at least one connecting wire may be positioned in the at least one transparent conductive layer. For example, multiple connecting wires may be positioned in the same transparent conductive layer, or a portion of the connecting wires may be positioned in one transparent conductive layer, while another portion of the connecting wires may be positioned in another transparent conductive layer. In this example, the connecting wires are made of a transparent conductive material, which helps ensure light transmittance in the first display area.

[0112] In some exemplary embodiments, the island region may further include: at least one second light-emitting element. The first pixel circuit in the island region may be electrically connected to at least one second light-emitting element emitting light of the same color and at least one first light-emitting element located in the transmissive region. For example, the orthographic projection of the first pixel circuit on the substrate may at least partially overlap with the orthographic projection of the connected second light-emitting element on the substrate. The first pixel circuit in this example can simultaneously drive the second light-emitting element and the first light-emitting element, which can reduce the number of pixel circuits in the first display area and help ensure light transmittance in the first display area.

[0113] In some exemplary embodiments, the island area may further include: at least one second pixel circuit and at least one second light-emitting element. The at least one second pixel circuit is electrically connected to the at least one second light-emitting element. The orthographic projection of the second pixel circuit on the substrate may at least partially overlap with the orthographic projection of the second light-emitting element to which it is connected on the substrate. For example, the second pixel circuit and the second light-emitting element may be connected in a one-to-one or one-to-many manner. In this example, different pixel circuits are provided to drive the first light-emitting element and the second light-emitting element, respectively, which is conducive to improving the display effect of the first display area.

[0114] In some exemplary embodiments, the light-emitting area of ​​a first light-emitting element may be smaller than the light-emitting area of ​​a second light-emitting element emitting light of the same color. In this example, the light-emitting area of ​​a light-emitting element may refer to the overlapping area of ​​the anode, organic light-emitting layer, and cathode of the light-emitting element exposed by the pixel definition layer. This configuration helps ensure light transmittance in the transmissive region.

[0115] In some exemplary embodiments, the plurality of second light-emitting elements in the island region and the plurality of first light-emitting elements in the transmission region may be located on the same insulating layer. In this example, by arranging the second light-emitting elements and the first light-emitting elements on the same insulating layer, it is advantageous to ensure display uniformity in the first display region.

[0116] In some exemplary embodiments, the transmissive region may include at least one first light-emitting element emitting a first color of light, at least one first light-emitting element emitting a second color of light, and at least one first light-emitting element emitting a third color of light. The first light-emitting element emitting the first color of light in the transmissive region and the plurality of second light-emitting elements in the island region may be located on the same insulating layer, while the first light-emitting element emitting the second color of light, the first light-emitting element emitting the third color of light, and the first light-emitting element emitting the first color of light in the transmissive region may be located on different insulating layers. The minimum distance between the first light-emitting element emitting the first color of light and the substrate may be greater than the minimum distance between the first light-emitting element emitting the second color of light and the substrate, and greater than the minimum distance between the first light-emitting element emitting the third color of light and the substrate. In this example, the minimum distance between the first light-emitting element and the substrate may refer to the vertical distance between the surface of the anode of the first light-emitting element facing away from the substrate and the substrate surface. In this example, removing the insulating layer beneath some of the first light-emitting elements in the transmissive region can help improve the light transmittance of the transmissive region.

[0117] In some exemplary embodiments, the first display area may further include: an inter-island connection area connecting adjacent island areas. The inter-island connection area may include: at least one third light-emitting element, and the first pixel circuit of the island area is electrically connected to at least one first light-emitting element located in the transmission area that emits light of the same color and at least one third light-emitting element located in the inter-island connection area. Alternatively, the inter-island connection area may include: at least one third light-emitting element and at least one third pixel circuit, and the at least one third pixel circuit is electrically connected to at least one third light-emitting element. For example, the third pixel circuit and the third light-emitting element may be connected in a one-to-one or one-to-many manner. In this example, by providing a third light-emitting element in the inter-island connection area, the pixel density of the first display area can be increased while ensuring the light transmittance of the first display area, thereby supporting high PPI display in the first display area.

[0118] In some exemplary embodiments, the display substrate may further include: a second display area located on at least one side of the first display area. The light transmittance of the second display area may be lower than the light transmittance of the first display area. The second display area may include: a plurality of second-area light-emitting elements and a plurality of second-area pixel circuits provided on the substrate. The plurality of second-area pixel circuits are electrically connected to the plurality of second-area light-emitting elements, and the second-area pixel circuits and the connected second-area light-emitting elements at least partially overlap in their orthographic projections on the substrate. For example, the second-area pixel circuits and the second-area light-emitting elements may be connected in a one-to-one or one-to-many manner. However, this embodiment is not limited to this.

[0119] In some exemplary embodiments, the pixel density of the first display area may be less than the pixel density of the second display area. In this example, the difference in pixel density between the first display area and the second display area is small, which helps to improve the display uniformity between the first display area and the second display area. In other examples, the pixel density of the first display area may be equal to the pixel density of the second display area. In other examples, the pixel density of the first display area may be greater than the pixel density of the second display area, thereby achieving a high PPI display in the first display area.

[0120] In some exemplary embodiments, the multiple transmissive regions are spaced apart from each other, and the multiple transmissive regions may include at least one of the following shapes: a rounded rectangle, a circle, an ellipse, an octagon, or a cross with twelve sides. For example, the multiple transmissive regions included in the display substrate may have substantially the same shape; alternatively, the multiple transmissive regions included in the display substrate may have a variety of shapes, such as some having the same shape and others having different shapes; or alternatively, the multiple transmissive regions may have different shapes. In some examples, the transmissive regions may be surrounded by island regions, or by island regions and inter-island connecting regions. The shape of the transmissive regions in this example helps reduce light diffraction, thereby improving the display and photography quality of the display device.

[0121] In some exemplary embodiments, a first light-emitting element located in the transmissive region may be electrically connected to a first pixel circuit, driven to emit light by the first pixel circuit; the first pixel circuit may be located in the island region or the inter-island connection region. A second light-emitting element located in the island region may be electrically connected to the second pixel circuit located in the island region. A third light-emitting element located in the inter-island connection region may be electrically connected to a third pixel circuit, driven to emit light by the third pixel circuit; the third pixel circuit may be located in the island region or the inter-island connection region. In some examples, the first, second, and third pixel circuits may be independently provided to drive the corresponding first, second, and third light-emitting elements, respectively. In other examples, the first pixel circuit may be provided in the island region or the inter-island connection region, while the second and third pixel circuits may be omitted, with the first pixel circuit simultaneously driving the first, second, and third light-emitting elements. In other examples, the first pixel circuit may be provided in the island region or the inter-island connection region, while the second pixel circuit may be provided in the island region, while the third pixel circuit may be omitted, with the first pixel circuit simultaneously driving the first and third light-emitting elements, and the second pixel circuit driving the second light-emitting element. In other examples, the first pixel circuit and the third pixel circuit may be provided in the island region or the inter-island connection region, and the second pixel circuit may be omitted. The first pixel circuit may simultaneously drive the first light-emitting element and the second light-emitting element, and the third pixel circuit may drive the third light-emitting element. Alternatively, the first pixel circuit may drive the first light-emitting element, and the third pixel circuit may simultaneously drive the second light-emitting element and the third light-emitting element. This embodiment is not limited to this.

[0122] The solution of this embodiment is illustrated below through some examples.

[0123] Figure 1 is a schematic diagram of a display substrate of at least one embodiment of the present disclosure. In some examples, as shown in Figure 1, the display substrate may include: a display area AA and a peripheral area BB located outside the display area AA. The display area AA of the display substrate may include: a first display area A1 and a second display area A2. The second display area A2 may at least partially surround the first display area A1. For example, the second display area A2 may surround the first display area A1. The peripheral area BB may surround the second display area A2. However, this embodiment is not limited to this. In other examples, the display area may include only the first display area, and the peripheral area may surround the first display area.

[0124] In some examples, as shown in Figure 1, the first display area A1 can be a light-transmitting display area, for example, it can be used as an under-screen camera (FDC, Full Display With Camera) area or a face recognition function area (Face ID) under the screen. The second display area A2 can be used as a normal display area. The light transmittance of the first display area A1 can be greater than the light transmittance of the second display area A2. For example, the orthographic projection of a sensor (such as a camera or other hardware) on the display substrate can be located within the first display area A1 of the display substrate. In some examples, as shown in Figure 1, the first display area A1 can be rectangular, and the size of the orthographic projection of a single sensor on the display substrate can be less than or equal to the size of the inscribed circle of the first display area A1, and the first display area A1 can cover the orthographic projection of one or more sensors on the display substrate. However, this embodiment is not limited to this. In other examples, the first display area A1 can be circular, and the size of the orthographic projection of a single sensor on the display substrate can be less than or equal to the size of the first display area A1.

[0125] In some examples, as shown in FIG1 , the first display area A1 can be located in the middle of the top of the display area AA. The second display area A2 can surround the first display area A1. However, this embodiment is not limited to this. For example, the first display area A1 can be located in the middle of the top, upper left corner, lower left corner, lower right corner, or upper right corner of the display area AA. For example, the second display area A2 can partially surround the first display area A1, such as being located on one side, two sides, or three sides of the first display area A1.

[0126] In some examples, as shown in FIG1 , the display area AA can be substantially rectangular, such as a rounded rectangle. The first display area A1 can be substantially rectangular. For example, the length of the first display area A1 along the first direction X can be greater than the length along the second direction Y. The first direction X intersects the second direction Y. For example, the first direction X can be perpendicular to the second direction Y. However, this embodiment is not limited to this. For example, the first display area A1 can be a circle, an ellipse, a semicircle, a pentagon, or other shapes.

[0127] In some examples, the display area AA may be provided with a plurality of sub-pixels. At least one sub-pixel may include a pixel circuit and a light-emitting element. The pixel circuit may be configured to drive the connected light-emitting element. For example, the pixel circuit may be configured to provide a driving current to drive the connected light-emitting element to emit light. The pixel circuit may include a plurality of transistors and at least one capacitor. For example, the pixel circuit may be a 3T1C, 4T1C, 5T1C, 5T2C, 6T1C, 7T1C, 8T1C or 8T2C 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.

[0128] In some examples, the multiple transistors in the pixel circuit can be P-type transistors or N-type transistors. Using the same type of transistors in the pixel circuit can simplify the process flow, reduce the difficulty of display substrate processing, and improve product yield. In other examples, the multiple transistors in the pixel circuit can include P-type transistors and N-type transistors.

[0129] 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 substrate, i.e., LTPS+Oxide (LTPO for short) display substrate, can take advantage of the advantages of both, achieve low-frequency driving, reduce power consumption, and improve display quality.

[0130] In some examples, the light-emitting element may be any one of a light-emitting diode (LED), an organic light-emitting diode (OLED), a quantum dot light-emitting diode (QLED), a micro-LED (including mini-LED or micro-LED), etc. For example, the light-emitting element may be an OLED, which may emit red light, green light, blue light, or white light, etc. when driven by its corresponding pixel circuit. The color of the light emitted by the light-emitting element may be determined as needed. In some examples, the light-emitting element may include: an anode, a cathode, and an organic light-emitting layer located between the anode and the cathode. The anode of the light-emitting element may be electrically connected to the corresponding pixel circuit. However, this embodiment is not limited to this.

[0131] In some examples, a pixel unit in display area AA may include three sub-pixels. For example, the three sub-pixels may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel. However, this embodiment is not limited to this. In other examples, a pixel unit in display area AA may include four sub-pixels, and the four sub-pixels may include two green sub-pixels, one red sub-pixel, and one blue sub-pixel. In other examples, a pixel unit may include four sub-pixels, and the four sub-pixels may be a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel.

[0132] In some examples, the shape of the light-emitting element can be a rectangle, a rhombus, a pentagon, or a hexagon. When a pixel unit includes three sub-pixels, the light-emitting elements of the three sub-pixels can be arranged horizontally, vertically, or in a triangular pattern. When a pixel unit includes four sub-pixels, the light-emitting elements of the four sub-pixels can be arranged horizontally, vertically, or in a square pattern. However, this embodiment is not limited to this.

[0133] In some examples, the pixel circuits within the display area AA may be connected to a plurality of first signal lines L1 extending along a first direction X and a plurality of second signal lines L2 extending along a second direction Y. For example, the plurality of first signal lines L1 may include at least scan lines and light-emitting control lines; and the plurality of second signal lines L2 may include at least data lines. However, this embodiment is not limited to this.

[0134] In some examples, the peripheral area BB may include a driver chip placement area B1 located on one side of the display area AA. The driver chip placement area B1 may be provided with multiple access pins that can be connected to multiple second signal lines L2 within the display area AA and may also be connected to a driver chip (IC). The driver chip may be configured to provide corresponding signals to the multiple second signal lines L2. For example, the driver chip may be configured to provide data signals to multiple data lines.

[0135] In some examples, the first display area A1 may include: a plurality of island areas A11 and a transmissive area TA located between adjacent island areas A11. For example, the plurality of island areas A11 may be arranged in an array. For example, a plurality of island areas arranged along a first direction X may be referred to as a row of island areas, and a plurality of island areas arranged along a second direction Y may be referred to as a column of island areas. The light transmittance of the transmissive area TA may be greater than the light transmittance of the island areas A11.

[0136] In some examples, the second display area A2 may include: a plurality of second-region pixel circuits 21 and a plurality of second-region light-emitting elements 22. At least one second-region pixel circuit 21 is electrically connected to at least one second-region light-emitting element 22 and is configured to drive the at least one second-region light-emitting element 22 to emit light. The orthographic projection of the second-region pixel circuit 21 on the substrate and the orthographic projection of the connected second-region light-emitting element 22 on the substrate may at least partially overlap. For example, the second-region pixel circuit and the second-region light-emitting element may be connected in a one-to-one drive (i.e., a one-to-one correspondence) or one-to-many drive (i.e., a one-to-many relationship). This embodiment is not limited to this.

[0137] Figure 2 is a partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. In some examples, as shown in Figures 1 and 2, within a plane parallel to the display substrate, the first display area A1 may include: a plurality of island areas A11 spaced apart from each other, a transmissive area TA located between adjacent island areas A11, and an inter-island connection area (e.g., including a first inter-island connection area A12a and a second inter-island connection area A12b) connecting adjacent island areas A11. Figure 2 illustrates four island areas A11 arranged in an array as an example.

[0138] In some examples, as shown in FIG2 , within a plane parallel to the display substrate, the shapes of the multiple islands A11 may be substantially the same, for example, they may be substantially rectangular, such as substantially square. Multiple inter-island connection regions may connect the multiple islands A11 to each other. For example, the first inter-island connection region A12a may be a strip region extending along the first direction X, and may connect the islands A11 arranged adjacently along the first direction X; the second inter-island connection region A12b may be a strip region extending along the second direction Y, and may connect the islands A11 arranged adjacently along the second direction Y. For example, each island A11 may connect two first inter-island connection regions A12a and two second inter-island connection regions A12b. An island A11 may be connected to four other islands surrounding the island A11 through four inter-island connection regions. However, this embodiment is not limited to this. In other examples, the shapes of the multiple islands A11 may be different, or may be partially the same.

[0139] In some examples, as shown in FIG2 , within a plane parallel to the display substrate, the multiple transmissive areas TA may have substantially the same shape, such as a twelve-sided "cross" shape. A transmissive area TA may be surrounded by multiple island areas A11 and multiple inter-island connecting areas. For example, a transmissive area TA may be surrounded by four island areas A11, two first inter-island connecting areas A12a, and two second inter-island connecting areas A12b arranged in a 2×2 array.

[0140] In some examples, the area of ​​a single transmissive area TA can be larger than the area of ​​a single island area A11 to improve the light transmittance of the first display area A1. However, this embodiment is not limited to this. In other examples, the area of ​​a single transmissive area TA can be less than or equal to the area of ​​a single island area A11 to improve the display effect of the first display area.

[0141] In some examples, the first display area A1 may include: a plurality of first-region pixel circuits and a plurality of first-region light-emitting elements. At least one first-region pixel circuit is electrically connected to at least one first-region light-emitting element and is configured to drive the at least one first-region light-emitting element to emit light. For example, the first-region pixel circuit and the first-region light-emitting element may have a one-to-one correspondence, or may have a one-to-many relationship. In this example, the plurality of first-region pixel circuits of the first display area A1 may include: a plurality of first pixel circuits 11 located in the island area A11; the plurality of first-region light-emitting elements of the first display area A1 may include: a plurality of first light-emitting elements 14 located in the transmission area TA, and a plurality of second light-emitting elements 15 located in the island area A11. This example increases the pixel density of the first display area by providing light-emitting elements in both the transmission area TA and the island area A11.

[0142] In some examples, as shown in FIG2 , a single island area A11 may be provided with two pixel units. For example, the two pixel units may be arranged sequentially along the second direction Y. However, this embodiment is not limited to this. For example, the two pixel units within the island area A11 may be arranged sequentially along the first direction X. In other examples, the island area A11 may be provided with one pixel unit, or one or two second light-emitting elements may be provided. This embodiment does not limit the number of second light-emitting elements provided in a single island area A11.

[0143] In some examples, as shown in FIG2 , the plurality of first pixel circuits 11 within the island area A11 can be electrically connected to the plurality of second light-emitting elements 15 in a one-to-one correspondence, i.e., the first pixel circuits 11 and the second light-emitting elements 15 are connected in a one-drive-one manner. However, this embodiment is not limited to this. In other examples, the first pixel circuits and the second light-emitting elements within the island area can be connected in a one-drive-many manner.

[0144] In some examples, as shown in FIG2 , each pixel unit in island A11 may include four second light-emitting elements 15 and four first pixel circuits 11 (e.g., first pixel circuits 11a, 11b, 11c, and 11d) connected to the four second light-emitting elements 15. The four first pixel circuits 11a, 11b, 11c, and 11d of each pixel unit may be arranged sequentially along the first direction X and electrically connected to the four second light-emitting elements 15 in a one-to-one correspondence. Taking the example of two pixel units arranged along the second direction Y in island A11, the eight first pixel circuits 11 included in the two pixel units may be arranged in two rows and four columns. The four first pixel circuits 11 in the same row are connected to the four second light-emitting elements of the same pixel unit. The orthographic projections of each second light-emitting element 15 and the first pixel circuit 11 to which it is connected may at least partially overlap on the substrate; alternatively, the orthographic projections of some second light-emitting elements 15 and the first pixel circuit 11 to which it is connected may at least partially overlap on the substrate, while the orthographic projections of other second light-emitting elements 15 and the first pixel circuit 11 to which it is connected may not overlap on the substrate.

[0145] In some examples, as shown in FIG2 , the four second light-emitting elements 15 of each pixel unit in the island area A11 may include a second light-emitting element 15a that emits a first color light, a second light-emitting element 15b that emits a second color light, and two second light-emitting elements 15c that emit a third color light. The two second light-emitting elements 15c that emit the third color light may be arranged in the same column along the second direction Y, the first light-emitting elements 15a and 15b may be arranged in the same row along the first direction X, and the second light-emitting elements 15a and 15b may be located in different rows and columns from the second light-emitting element 15c. The first pixel circuit 11a may be electrically connected to one first light-emitting element 15a, the first pixel circuit 11b may be electrically connected to one second light-emitting element 15c, the first pixel circuit 11c may be electrically connected to another second light-emitting element 15c, and the first pixel circuit 11d may be electrically connected to one second light-emitting element 15b. However, this embodiment is not limited to this.

[0146] In some examples, the first color light may be red, the second color light may be blue, and the third color light may be green. The orthographic projections of the light-emitting areas of the second light-emitting elements 15a and 15b on the substrate may be approximately hexagonal; the orthographic projections of the light-emitting areas of the second light-emitting element 15c on the substrate may be approximately pentagonal. However, this embodiment is not limited to this.

[0147] In some examples, the light emitting area of ​​a single second light emitting element 15a may be smaller than the light emitting area of ​​a single second light emitting element 15b, and the light emitting area of ​​a single second light emitting element 15c may be smaller than the light emitting area of ​​a single second light emitting element 15a.

[0148] In some examples, as shown in FIG2 , the transmission area TA may include a plurality of first light-emitting elements 14, for example, at least one first light-emitting element 14a that emits light of a first color, at least one first light-emitting element 14b that emits light of a second color, and at least one first light-emitting element 14c that emits light of a third color. The plurality of first light-emitting elements 14 within a single transmission area TA may be evenly distributed throughout the transmission area TA. The number of first light-emitting elements 14 within a single transmission area TA may be different from the number of second light-emitting elements 15 within a single island area A11. For example, the number of first light-emitting elements 14 within a single transmission area TA may be greater than the number of second light-emitting elements 15 within a single island area A11. However, this embodiment is not limited thereto. For example, the number of first light-emitting elements within a single transmission area TA may be less than or equal to the number of second light-emitting elements within a single island area A11.

[0149] In some examples, the light-emitting areas of the first light-emitting elements 14a, 14b, and 14c can be substantially circular or elliptical in their orthographic projections onto the substrate. The light-emitting area of ​​a single first light-emitting element 14a can be smaller than the light-emitting area of ​​a single first light-emitting element 14b, and the light-emitting area of ​​a single first light-emitting element 14c can be smaller than the light-emitting area of ​​a single first light-emitting element 14a.

[0150] In some examples, the arrangement of the plurality of first light-emitting elements 14 within the transmissive area TA can be the same as the arrangement of the plurality of second light-emitting elements 15 within the island area A11. For example, the first light-emitting elements 14a emitting the first color light and the first light-emitting elements 14b emitting the second color light can be arranged in an array along the first direction X and the second direction Y, and the first light-emitting elements 14c emitting the third color light can be arranged in an array along the first direction X and the second direction Y. The first light-emitting elements 14c and the first light-emitting elements 14a and 14b can be located in different columns and rows. However, this embodiment is not limited to this. In other examples, the arrangement of the plurality of first light-emitting elements within the transmissive area TA can be different from the arrangement of the plurality of second light-emitting elements within the island area A11.

[0151] In some examples, the light-emitting area of ​​the first light-emitting element 14 in the transmissive area TA can be smaller than the light-emitting area of ​​the second light-emitting element 15 emitting the same color light in the island area A11. For example, the light-emitting area of ​​the first light-emitting element 14a can be smaller than the light-emitting area of ​​the second light-emitting element 15a, the light-emitting area of ​​the first light-emitting element 14b can be smaller than the light-emitting area of ​​the second light-emitting element 15b, and the light-emitting area of ​​the first light-emitting element 14c can be smaller than the light-emitting area of ​​the second light-emitting element 15c. This example can ensure the display effect of the island area A11 and the light transmittance of the transmissive area TA. However, this embodiment is not limited to this. In other examples, the light-emitting area of ​​the first light-emitting element can be greater than or equal to the light-emitting area of ​​the second light-emitting element emitting the same color light.

[0152] In some examples, the first light-emitting element 14 in the transmissive area TA can be electrically connected to the first pixel circuit 11 in the adjacent island area A11. The first pixel circuit 11 in the island area A11 and the first light-emitting element 14 in the transmissive area TA can be connected in a one-drive-many manner. For example, the first pixel circuit 11 can be connected to multiple first light-emitting elements 14 in the transmissive area TA that emit light of the same color. The multiple first light-emitting elements 14 connected to the first pixel circuit 11 can be located in the same transmissive area TA, or in different transmissive areas TA.

[0153] In some examples, the first pixel circuit 11 within the island area A11 can be configured to drive multiple first-region light-emitting elements that emit the same color light (for example, including a second light-emitting element 15 located within the same island area A11 and multiple first light-emitting elements 14 within at least one transmissive area TA adjacent to the island area A11). In this example, the first pixel circuit disposed within the island area A11 is used to drive the first light-emitting element in the transmissive area, which can help ensure light transmittance in the transmissive area. Using the first pixel circuit to simultaneously drive the first and second light-emitting elements can help reduce the layout space of the pixel circuits and help ensure light transmittance in the first display area.

[0154] In some examples, as shown in FIG2 , a first pixel circuit 11 can be connected to at least one first light-emitting element 14 via at least one connecting line. Multiple first light-emitting elements 14 emitting the same color light within the same transmissive area TA can be connected via a second connecting line 32. One of the multiple first light-emitting elements 14 can be connected via a first connecting line 31 to a second light-emitting element 15 emitting the same color light within an adjacent island area A11. This second light-emitting element 15 is connected to the same first pixel circuit 11, thereby enabling multiple first light-emitting elements 14 emitting the same color light within the transmissive area TA and one second light-emitting element 15 within the island area A11 to be connected to the same first pixel circuit 11. FIG2 illustrates only the connection relationship between several first light-emitting elements 14 and second light-emitting elements 15 as an example, and omits the connection relationship between the remaining first light-emitting elements 14 and second light-emitting elements 15. For example, a first light-emitting element 14 can be connected to an adjacent second light-emitting element 15 emitting the same color light via a first connecting line 31, and multiple first light-emitting elements 14 connected to the same first pixel circuit 11 can be connected via a second connecting line 32. In some examples, the first connection lines 31 and the second connection lines 32 connected to the plurality of first light-emitting elements 14 connected to the same first pixel circuit 11 may be an integrated structure connected to each other. However, this embodiment is not limited to this.

[0155] In some examples, the first light-emitting element 14 or second light-emitting element 15 to be connected can be determined based on the distance between the first light-emitting element 14 in the transmission area TA and the surrounding first light-emitting elements 14 and second light-emitting elements 15 that emit light of the same color. For example, the first light-emitting element 14 can be connected to the first light-emitting element 14 or second light-emitting element 15 that emits light of the same color that is closest to it, so as to ensure that the length of the connected first connecting wire 31 or second connecting wire 32 is the shortest, thereby reducing the impact on the display effect of the first display area caused by the increased load caused by the longer connecting wires.

[0156] Figure 3 illustrates an example circuit and wiring layout for the first display area in Figure 2 . In some examples, as shown in Figures 2 and 3 , a single island area A11 may include multiple first pixel circuits 11. The first pixel circuits 11 may be connected to multiple first signal lines L1 extending along a first direction X, and may also be connected to multiple second signal lines L2 extending along a second direction Y. The first inter-island connection area A12a may be provided with multiple first signal lines L1 extending along the first direction X, and the second inter-island connection area A12b may be provided with multiple second signal lines L2 extending along the second direction Y.

[0157] In some examples, the plurality of first signal lines L1 and the plurality of second signal lines L2 can be made of metal material. The edges of the first inter-island connection area A12a and the second inter-island connection area A12b can be determined by the peripheral edge shape of the signal line set in the inter-island connection area. For example, the edges of the first inter-island connection area A12a and the second inter-island connection area A12b can be non-flat edges, such as having a protrusion or a recess, or can be roughly arc-shaped. However, this embodiment is not limited to this. In other examples, the edges of the first inter-island connection area A12a and the second inter-island connection area A12b can be determined by the peripheral edge shape of a light-shielding layer (for example, a light-shielding layer made of a metal material or a black light-shielding layer made of other materials), and the light-shielding layer can cover the non-luminous area of ​​the island area and the inter-island connection area.

[0158] In some examples, the signal lines within the first inter-island connection area A12a and the second inter-island connection area A12b can be made of a transparent conductive material, allowing adjacent transmissive areas TA to connect with each other. The transmissive areas TA can surround the island area A11. This example can help improve the light transmittance of the first display area.

[0159] Figure 4 is a schematic partial cross-sectional view of a display substrate according to at least one embodiment of the present disclosure. Figure 4 is a schematic partial cross-sectional view taken along the Q-Q' direction in Figure 1. In some examples, as shown in Figure 4 , in a direction perpendicular to the display substrate, the display substrate may include: a substrate 30, and a circuit structure layer, a light-emitting structure layer, and an encapsulation structure layer sequentially disposed on substrate 30. In some examples, the display substrate may also include other film layers, such as a touch structure layer and a color filter layer. This embodiment is not limited to this.

[0160] In some examples, the circuit structure layer of the first display area A1 may include: a first pixel circuit 11 located in the island area A11; the light-emitting structure layer of the first display area A1 may include: a second light-emitting element 15 located in the island area A11 and a first light-emitting element 14 located in the transmission area TA. The circuit structure layer of the second display area A2 may include: a second-region pixel circuit 21; the light-emitting structure layer of the second display area A2 may include: a second-region light-emitting element 22. FIG4 illustrates one transistor and one second-region light-emitting element 22 of one second-region pixel circuit 21 of the second display area A2 as an example, and illustrates one transistor of the first pixel circuit 11 of the first display area A1, one second light-emitting element 15 emitting light of the same color, and two first light-emitting elements 14 (e.g., two first light-emitting elements 14 and one second light-emitting element 15 emitting light of the first color) as an example.

[0161] In some examples, the circuit structure layer may include: a shielding layer 421 disposed on the substrate 30, a semiconductor layer, a first conductive layer, a second conductive layer, and a third conductive layer. A first insulating layer 301 (also referred to as a first buffer layer) may be disposed between the shielding layer 421 and the substrate 30; a second insulating layer 302 (also referred to as a second buffer layer) may be disposed between the shielding layer 421 and the semiconductor layer; a third insulating layer 303 (also referred to as a first gate insulating layer) may be disposed between the semiconductor layer and the first conductive layer; a fourth insulating layer 304 (also referred to as a second gate insulating layer) may be disposed between the first and second conductive layers; a fifth insulating layer 305 (also referred to as an interlayer insulating layer) may be disposed between the second and third conductive layers; and a sixth insulating layer 306 (also referred to as a first planarizing layer) may be disposed on the side of the third conductive layer away from the substrate 30. The first conductive layer may also be referred to as a first gate metal layer, the second conductive layer may also be referred to as a second gate metal layer, and the third conductive layer may also be referred to as a first source / drain metal layer. In some examples, the shielding layer 421, the first conductive layer, the second conductive layer, and the third conductive layer may be made of metal.

[0162] In some examples, the first to fifth insulating layers 301 to 305 may be inorganic insulating layers, and the sixth insulating layer 306 may be an organic insulating layer. However, this embodiment is not limited thereto. In other examples, an inorganic insulating layer may be disposed between the sixth insulating layer 306 and the third conductive layer.

[0163] In some examples, the blocking layer 421 may be located at least in the island area A11 of the first display area A1, and the orthographic projection of the blocking layer 421 on the substrate 30 may cover the orthographic projection of the active layer of at least one transistor of the first pixel circuit 11 in the island area A11 on the substrate 30. For example, if the first pixel circuit 11 includes multiple transistors, the orthographic projection of the blocking layer 421 on the substrate may cover the orthographic projection of the active layer of all transistors of the first pixel circuit 11 on the substrate; or, the orthographic projection of the blocking layer 421 on the substrate may cover the orthographic projection of the active layer of a portion of the multiple transistors of the first pixel circuit 11 on the substrate. In this example, by providing the blocking layer 421 in the island area A11 to cover the active layer of the transistor of the first pixel circuit 11, interference of external light on the transistor of the first pixel circuit 11 can be prevented, thereby ensuring the performance of the transistor of the first pixel circuit 11.

[0164] In some examples, the semiconductor layer may include at least: an active layer of a transistor of the first pixel circuit 11 located in the island area A11, and an active layer of a transistor of the second region pixel circuit 21 located in the second display area A2. The first conductive layer may include at least: a gate electrode of the transistor of the first pixel circuit 11 located in the island area A11 and a first electrode of a storage capacitor (not shown), and a gate electrode of the transistor of the second region pixel circuit 21 located in the second display area A2 and a first electrode of a storage capacitor (not shown). The second conductive layer may include at least: a second electrode of the storage capacitor of the first pixel circuit 11 (not shown), and a second electrode of the storage capacitor of the second region pixel circuit 21 (not shown). The third conductive layer may include at least: a first electrode and a second electrode of the transistor of the first pixel circuit 11, and a first electrode and a second electrode of the transistor of the second region pixel circuit 21.

[0165] In some examples, the light-emitting structure layer may include an anode layer, a pixel definition layer 411, an organic functional layer, and a cathode layer, arranged in sequence. The anode layer may include at least the anode 141 of the first light-emitting element 14 located in the transmission area TA, the anode 151 of the second light-emitting element 15 located in the island area A11, and the anode 221 of the second-region light-emitting element 22 located in the second display area A2. The organic functional layer may include at least the organic light-emitting layer 142 of the first light-emitting element 14 located in the transmission area TA, the organic light-emitting layer 152 of the second light-emitting element 15 located in the island area A11, and the organic light-emitting layer 222 of the second-region light-emitting element 22 located in the second display area A2. The cathode layer may include at least the cathode 143 of the first light-emitting element 14 located in the transmission area TA, the cathode 153 of the second light-emitting element 15 located in the island area A11, and the cathode 223 of the second-region light-emitting element 22 located in the second display area A2.

[0166] In some examples, the anode 221 of the second-region light-emitting element 22 can be located on the sixth insulating layer 306 and connected to the second-region pixel circuit 21 through a via hole defined in the sixth insulating layer 306. The pixel definition layer 411 can have a third pixel opening defined in the second display area A2, which can expose at least a portion of the surface of the anode 221 of the second-region light-emitting element 22. The organic light-emitting layer 222 and cathode 223 of the second-region light-emitting element 22 can be sequentially stacked within the third pixel opening.

[0167] In some examples, the anode 151 of the second light-emitting element 15 can be located on the sixth insulating layer 306 and connected to the first pixel circuit 11 through a via hole defined in the sixth insulating layer 306. The pixel definition layer 411 can have a second pixel opening defined in the island area A11 of the first display area A1. The second pixel opening can expose at least a portion of the surface of the anode 151 of the second light-emitting element 15. The organic light-emitting layer 152 and cathode 153 of the second light-emitting element 15 can be sequentially stacked within the second pixel opening.

[0168] In some examples, the anode 141 of the first light-emitting element 14 can be located on the second insulating layer 302. For example, after the sixth insulating layer 306 is prepared, the sixth insulating layer 306, the fifth insulating layer 305, the fourth insulating layer 304, and the third insulating layer 303 in the transmission area TA can be removed, so that the anode 141 of the first light-emitting element 14 can be formed on the second insulating layer 302 and connected to the first connecting line 31 and the second connecting line 32 through the via hole opened in the second insulating layer 302. However, this embodiment is not limited to this. In other examples, the anode 141 of the first light-emitting element 14 can be located on the third insulating layer, the fourth insulating layer, the fifth insulating layer, or the sixth insulating layer.

[0169] In this example, the first connecting line 31 and the second connecting line 32 can be an integrated structure connected to each other and formed on the same layer as the shielding layer 421. The anodes 141 of the two first light-emitting elements 14 emitting the same color light in the transmission area TA can be connected via the second connecting line 32. The anodes 141 of the two first light-emitting elements 14 can be connected to the anode 151 of the second light-emitting element 15 emitting the same color light in the island area A11 via the first connecting line 31, thereby achieving connection to the same first pixel circuit 11. The anode 151 of the second light-emitting element 15 in the island area A11 can be connected to the first connecting line 31 via a via hole penetrating the sixth insulating layer 306, the fifth insulating layer 305, the fourth insulating layer 304, the third insulating layer 303, and the second insulating layer 302. However, this embodiment is not limited to this. In other examples, the first connecting line 31 and the second connecting line 32 can be formed on different layers from the shielding layer 421. For example, the first connecting line 31 and the second connecting line 32 can be formed on the same layer as the first conductive layer, the second conductive layer, or the third conductive layer. In other examples, the first connection line 31 and the second connection line 32 may be in different layers. For example, the first connection line 31 may be in the same layer as the shielding layer 421, and the second connection line 32 may be located on the side of the first connection line 31 close to the substrate 30, or on the side of the first connection line 31 away from the substrate 30.

[0170] In this example, the first light-emitting element 14 and the second light-emitting element 15 are located on different insulating layers. By removing multiple insulating layers on the side of the first light-emitting element 14 near the substrate 30 in the transmissive area TA, the first light-emitting element 14 can be positioned closer to the substrate 30, facilitating the design of the first and second connecting wires, which are arranged on the same layer as the shielding layer. Furthermore, by removing some of the insulating layers in the transmissive area TA, this example improves the light transmittance in the transmissive area.

[0171] In some examples, the cathode 223 of the second region light-emitting element 22, the cathode 143 of the first light-emitting element 14, and the cathode 153 of the second light-emitting element 15 can be interconnected as an integral structure. The cathode layer of the second display area A2 can be a solid structure, while the cathode layer of the first display area A1 can be patterned. For example, the cathode layer in areas outside the light-emitting elements can be removed to improve the light transmittance of the first display area A1.

[0172] In some examples, the encapsulation structure layer may include a stacked first encapsulation layer 401, a second encapsulation layer 402, and a third encapsulation layer 403. The first encapsulation layer 401 and the third encapsulation layer 403 may be made of inorganic materials, and the second encapsulation layer 402 may be made of organic materials. The second encapsulation layer 402 may be arranged between the first encapsulation layer 401 and the third encapsulation layer 403 to form an inorganic material / organic material / inorganic material stacked structure, which can ensure that external water vapor cannot enter the light-emitting structure layer.

[0173] In some examples, a sensor 92 may be disposed on a non-display surface of the display substrate, and an orthographic projection of the sensor 92 on the display substrate may overlap with the first display area A1 of the display substrate.

[0174] Figure 5 is another partial cross-sectional schematic diagram of a display substrate according to at least one embodiment of the present disclosure. Figure 5 is another partial cross-sectional schematic diagram along the Q-Q' line in Figure 1. In some examples, as shown in Figure 5, the anode 141 of the first light-emitting element 14 in the transmissive area TA and the anode 151 of the second light-emitting element 15 in the island area A11 can both be located on the sixth insulating layer 306. The anodes 141 of the first light-emitting elements 14 in the transmissive area TA that emit light of the same color and are connected to the same first pixel circuit 11 can be connected via a second connecting wire 32, and the anode 141 of one of the first light-emitting elements 14 can be connected to the anode 151 of the second light-emitting element 15 via a first connecting wire 31.

[0175] In some examples, the anode layer may include: a stacked first sub-conductive layer, a second sub-conductive layer, and a third sub-conductive layer. The second sub-conductive layer is located between the first sub-conductive layer and the third sub-conductive layer, the first sub-conductive layer is located on the side of the second sub-conductive layer close to the substrate 30, and the third sub-conductive layer is located on the side of the second sub-conductive layer away from the substrate 30. The materials of the first sub-conductive layer and the third sub-conductive layer can be the same, for example, a transparent conductive material such as indium tin oxide (ITO) can be used; the second sub-conductive layer can be made of a metal material such as silver (Ag). The anode of each light-emitting element may include three stacked anode sub-layers, the first anode sub-layer can be located in the first sub-conductive layer, the second anode sub-layer can be located in the second sub-conductive layer, and the third anode sub-layer can be located in the third sub-conductive layer.

[0176] In some examples, the first connecting line 31 and the second connecting line 32 may be co-layered with the first sub-conductive layer of the anode layer. However, this embodiment is not limited to this. For example, the first connecting line 31 and the second connecting line 32 may be co-layered with the second sub-conductive layer or the third sub-conductive layer. In other examples, the first connecting line 31 and the second connecting line 32 may be co-layered with different sub-conductive layers of the anode layer. For example, the first connecting line 31 may be co-layered with the first sub-conductive layer, and the second connecting line 32 may be co-layered with the third sub-conductive layer.

[0177] In this example, the first and second connecting lines 31 and 32 are made of a transparent conductive material and are fabricated simultaneously with the anode layer. This improves the light transmittance of the transmissive region and reduces the number of fabrication steps, thereby saving costs. The remaining description of the display substrate of this example can be found in the description of the previous embodiment and will not be repeated here.

[0178] Figure 6 is another partial cross-sectional schematic diagram of the display substrate of at least one embodiment of the present disclosure. Figure 6 is another partial cross-sectional schematic diagram along the Q-Q' direction in Figure 1. In some examples, as shown in Figure 6, in a direction perpendicular to the display substrate, the display substrate may include: a substrate 30, and a circuit structure layer, a transparent conductive layer, a light-emitting structure layer, and an encapsulation structure layer arranged on the substrate 30. The transparent conductive layer may be located between the circuit structure layer and the light-emitting structure layer. The transparent conductive layer may be located on the sixth insulating layer 306 of the circuit structure layer, and a seventh insulating layer (also referred to as a second flat layer) 307 may be provided between the transparent conductive layer and the light-emitting structure layer. The anode layer of the light-emitting structure layer may be located on the seventh insulating layer 307. For example, the transparent conductive layer may be made of a transparent conductive material, such as ITO.

[0179] In some examples, the transparent conductive layer may include: a second anode connecting electrode 36 located in the second display area A2, a first anode connecting electrode 35 located in the first display area A1, a first connecting line 31 and a second connecting line 32. The anode 221 of the second-region light-emitting element 22 can be connected to the second anode connecting electrode 36 through a via hole opened in the seventh insulating layer 307, and the second anode connecting electrode 36 can be connected to the second-region pixel circuit 21 through a via hole opened in the sixth insulating layer 306, thereby realizing electrical connection between the anode 221 of the second-region light-emitting element 22 and the second-region pixel circuit 21.

[0180] In some examples, the anode 151 of the second light-emitting element 15 can be connected to the first anode connection electrode 35 through a via hole opened in the seventh insulating layer 307, and the first anode connection electrode 35 can be connected to the first pixel circuit 11 through a via hole opened in the sixth insulating layer 306. The anode 141 of the first light-emitting element 14 can be connected to the first connection line 31 or the second connection line 32 through a via hole opened in the seventh insulating layer 307. The first anode connection electrode 35, the first connection line 31 and the second connection line 32 electrically connected to the same first pixel circuit 11 can be an integrated structure connected to each other, so that two first light-emitting elements 14 and one second light-emitting element 15 emitting light of the same color are electrically connected to the same first pixel circuit 11. However, this embodiment is not limited to this. In other examples, the display substrate may include multiple transparent conductive layers made of transparent conductive material, and the first connection line and the second connection line may be located in different transparent conductive layers.

[0181] In this example, the first and second connecting lines are made of transparent conductive material, which can help improve the light transmittance of the transmission area. The rest of the description of the display substrate of this example can refer to the description of the previous embodiment, so it will not be repeated here.

[0182] Figure 7 is another partial cross-sectional schematic diagram of the display substrate of at least one embodiment of the present disclosure. Figure 7 is another partial cross-sectional schematic diagram along the Q-Q' direction in Figure 1. In some examples, as shown in Figure 7, in the direction perpendicular to the display substrate, the display substrate may include: a substrate 30, and a circuit structure layer, a first transparent conductive layer, a second transparent conductive layer, a light-emitting structure layer, and an encapsulation structure layer arranged on the substrate 30. The first transparent conductive layer may be located between the circuit structure layer and the second transparent conductive layer, the first transparent conductive layer may be located on the sixth insulating layer 306 of the circuit structure layer, a seventh insulating layer 307 may be provided between the first transparent conductive layer and the second transparent conductive layer, and an eighth insulating layer (also referred to as a third flat layer) 308 may be provided on the side of the second transparent conductive layer away from the substrate 30. The first transparent conductive layer and the second transparent conductive layer may be made of transparent conductive materials, for example, they may include ITO.

[0183] In some examples, the first transparent conductive layer may include: a second anode connecting electrode 36 located in the second display area A2; a first anode connecting electrode 35 located in the island area A11 of the first display area A1; and the second transparent conductive layer may include: a fourth anode connecting electrode 38 located in the second display area A2; and a third anode connecting electrode 37 located in the island area A11 of the first display area A1. The anode 221 of the second-region light-emitting element 22 may be connected to the fourth anode connecting electrode 38 via a via hole defined in the eighth insulating layer 308, the fourth anode connecting electrode 38 may be connected to the second anode connecting electrode 36 via a via hole defined in the seventh insulating layer 307, and the second anode connecting electrode 36 may be connected to the second-region pixel circuit 21 via a via hole defined in the sixth insulating layer 306. The anode 151a of the second light-emitting element 15a can be connected to the third anode connecting electrode 37 through a via hole opened in the eighth insulating layer 308, the third anode connecting electrode 37 can be connected to the first anode connecting electrode 35 through a via hole opened in the seventh insulating layer 307, and the first anode connecting electrode 35 can be connected to the first pixel circuit 11 through a via hole opened in the sixth insulating layer 306.

[0184] In some examples, the second light-emitting element 15a (including the anode 151a, the organic light-emitting layer 152a, and the cathode 153a) can be located on the eighth insulating layer 308. The second light-emitting element in the island area A11 and a portion of the first light-emitting element in the transmission area TA (such as the first light-emitting element 14a) can be located on the same insulating layer. For example, the second light-emitting element in the island area A11 and the first light-emitting element in the transmission area TA that emits the first color light can be located on the same insulating layer. In other examples, the second light-emitting element in the island area A11 and the first light-emitting element in the transmission area TA that emits the second color light or the third color light can be located on the same insulating layer.

[0185] In some examples, first light-emitting elements emitting light of different colors within the transmission area TA may be located on different insulating layers, and first light-emitting elements emitting light of the same color may be located on the same insulating layer. For example, the first light-emitting element 14a (including the anode 141a, the organic light-emitting layer 142a, and the cathode 143a) emitting light of the first color within the transmission area TA may be located on the eighth insulating layer 308, the first light-emitting element 14b (including the anode 141b, the organic light-emitting layer 142b, and the cathode 143b) emitting light of the second color may be located on the sixth insulating layer 306, and the first light-emitting element 14c (including the anode 141c, the organic light-emitting layer 142c, and the cathode 143c) emitting light of the third color may be located on the seventh insulating layer 307. The minimum distance between the first light-emitting element 14a and the substrate 30 may be greater than the minimum distance between the first light-emitting element 14c and the substrate 30, and the minimum distance between the first light-emitting element 14c and the substrate 30 may be greater than the minimum distance between the first light-emitting element 14b and the substrate 30. However, this embodiment is not limited to this. In other examples, the first light-emitting element emitting the first color light and the second color light may be located on the same insulating layer, and the first light-emitting element emitting the third color light and the first light-emitting element emitting the first color light may be located on different insulating layers.

[0186] In other examples, the insulating layer on which the first light-emitting elements are disposed can be determined based on the distance between the first light-emitting elements and the center of the transmission area TA. For example, multiple first light-emitting elements near the center of the transmission area TA can be located on the same insulating layer, while multiple first light-emitting elements far from the center of the transmission area TA can be located on the same insulating layer, but on a different insulating layer than the multiple first light-emitting elements near the center of the transmission area TA. For example, the minimum distance between the multiple first light-emitting elements far from the center of the transmission area TA and the substrate can be greater than the minimum distance between the multiple first light-emitting elements near the center of the transmission area TA and the substrate.

[0187] This example removes portions of the insulating layer within the transmissive region, reducing its thickness and improving its light transmittance. Furthermore, placing first light-emitting elements emitting different colors of light on different insulating layers optimizes the display quality within the transmissive region. This example also reduces diffraction by providing insulating layers of varying heights within the transmissive region.

[0188] In some examples, the anode layer may include: a stacked first sub-conductive layer, a second sub-conductive layer, and a third sub-conductive layer. The materials of the first sub-conductive layer and the third sub-conductive layer may be the same, for example, a transparent conductive material may be used, such as indium tin oxide (ITO); the second sub-conductive layer may be made of a metal material, such as silver (Ag). The first connecting line 31 or the second connecting line 32 connected to the first light-emitting element may be a co-layer structure with a sub-conductive layer of the anode layer, for example, both may be co-layer structures with the first sub-conductive layer. For example, the anode 141a of the first light-emitting element 14a can be connected to the anode 151a of the second light-emitting element 15a through the first connecting line 31 to achieve electrical connection with the same first pixel circuit 11, and the first connecting line 31 and the anode 141a of the first light-emitting element 14a and the anode 151a of the second light-emitting element 15a may be an integrated structure connected to each other in the first sub-conductive layer. However, this embodiment is not limited to this. In other examples, the first connecting line and the second connecting line connected to the first light-emitting element emitting light of different colors can be the same layer structure as different sub-conductive layers. For example, the first connecting line and the second connecting line connected to the first light-emitting element emitting light of the first color and the second color can be the same layer structure as the first sub-conductive layer, and the first connecting line and the second connecting line connected to the first light-emitting element emitting light of the third color can be the same layer structure as the third sub-conductive layer.

[0189] In this example, the first and second connecting lines are made of a transparent conductive material and are fabricated simultaneously with the anode layer. This helps ensure light transmittance in the transmissive region and reduces the number of fabrication steps, thereby saving costs. The remaining description of the display substrate of this example can be found in the description of the previous embodiment and will not be repeated here.

[0190] Figure 8 is another partial cross-sectional schematic diagram of the display substrate of at least one embodiment of the present disclosure. Figure 8 is another partial cross-sectional schematic diagram along the Q-Q' direction in Figure 1. In some examples, as shown in Figure 8, in a direction perpendicular to the display substrate, the display substrate may include: a substrate 30, and a circuit structure layer, a first transparent conductive layer, a second transparent conductive layer, a light-emitting structure layer, and an encapsulation structure layer arranged on the substrate 30.

[0191] In some examples, first light-emitting elements emitting light of different colors within the transmission area TA may be located on different insulating layers, and first light-emitting elements emitting light of the same color may be located on the same insulating layer. For example, the first light-emitting element 14a (including the anode 141a, the organic light-emitting layer 142a, and the cathode 143a) emitting light of the first color within the transmission area TA may be located on the eighth insulating layer 308, the first light-emitting element 14b (including the anode 141b, the organic light-emitting layer 142b, and the cathode 143b) emitting light of the second color may be located on the sixth insulating layer 306, and the first light-emitting element 14c (including the anode 141c, the organic light-emitting layer 142c, and the cathode 143c) emitting light of the third color may be located on the seventh insulating layer 307.

[0192] In some examples, the first connecting line 31 or the second connecting line 32 connected to the first light-emitting element 14a that emits the first color light in the transmission area TA can be located in the second transparent conductive layer, the first connecting line 31 or the second connecting line 32 connected to the first light-emitting element 14c that emits the third color light in the transmission area TA can be located in the first transparent conductive layer, and the first connecting line 31 or the second connecting line 32 connected to the first light-emitting element 14b that emits the second color light in the transmission area TA can be located in the third conductive layer. However, this embodiment is not limited to this. In other examples, the first connecting line 31 or the second connecting line 32 connected to the second light-emitting element 14b that emits the second color light in the transmission area TA can be located in a transparent conductive layer on the side of the third conductive layer away from the substrate.

[0193] In this example, the first and second connecting lines connected to the first light-emitting elements emitting light of different colors are arranged in different film layers, which allows for the rational arrangement of multiple first and second connecting lines. The remaining description of the display substrate of this example can be referred to the description of the previous embodiment, and will not be repeated here.

[0194] Figure 9 is another partial cross-sectional schematic diagram of a display substrate according to at least one embodiment of the present disclosure. Figure 9 is another partial cross-sectional schematic diagram along the Q-Q' direction in Figure 1. In some examples, as shown in Figure 9, in a direction perpendicular to the display substrate, the display substrate may include: a substrate 30, and a circuit structure layer, a first transparent conductive layer, a second transparent conductive layer, a light-emitting structure layer, and an encapsulation structure layer disposed on substrate 30. The first transparent conductive layer and the second transparent conductive layer may be made of a transparent conductive material, such as ITO.

[0195] In some examples, the second light-emitting element 15b (including the anode 151b, the organic light-emitting layer 152b, and the cathode 153b) of the island area A11 can be located on the eighth insulating layer 308. The first light-emitting elements emitting light of different colors in the transmission area TA can be located on different insulating layers, and the first light-emitting elements emitting light of the same color can be located on the same insulating layer. For example, the first light-emitting element 14a (including the anode 141a, the organic light-emitting layer 142a, and the cathode 143a) emitting light of the first color in the transmission area TA can be located on the eighth insulating layer 308, the first light-emitting element 14b (including the anode 141b, the organic light-emitting layer 142b, and the cathode 143b) emitting light of the second color can be located on the second insulating layer 302, and the first light-emitting element 14c (including the anode 141c, the organic light-emitting layer 142c, and the cathode 143c) emitting light of the third color can be located on the sixth insulating layer 306.

[0196] In some examples, the first connecting line 31 or the second connecting line 32 connected to the first light-emitting element 14a that emits the first color light in the transmission area TA can be located in the second transparent conductive layer; the first connecting line 31 or the second connecting line 32 connected to the first light-emitting element 14c that emits the third color light in the transmission area TA can be located in the third conductive layer; the first connecting line 31 or the second connecting line 32 connected to the first light-emitting element 14b that emits the second color light in the transmission area TA can be in the same layer structure as the shielding layer 421. For example, the anode 151b of the second light-emitting element 15b can be connected to the first anode connecting electrode 35 through the third anode connecting electrode 37, and the first anode connecting electrode 35 can be electrically connected to the first connecting line 31 through a via hole penetrating the sixth insulating layer 306, the fifth insulating layer 305, the fourth insulating layer 304, the third insulating layer 303 and the second insulating layer 302. The first anode connecting electrode 35 can also be electrically connected to the first pixel circuit 11 through the via hole opened in the sixth insulating layer 306, thereby realizing the connection between the second light-emitting element 15b and the first light-emitting element 14b and the same first pixel circuit 11.

[0197] In this example, part of the insulating layer in the transmission area is removed, which can reduce the thickness of the insulating layer in the transmission area, which is beneficial to improving the light transmittance of the transmission area; moreover, the first light-emitting elements emitting different colors of light are arranged on different insulating layers, which can optimize the display effect of the transmission area. By arranging insulating layers of different heights in the transmission area, it is beneficial to reduce diffraction. In addition, in this example, the first connecting wire and the second connecting wire connected to the first light-emitting element are arranged in a suitable film layer according to the insulating layer where the first light-emitting element is located, which is not only beneficial for the arrangement of the connecting wires, but also helps to simplify the preparation process and save costs. The rest of the description of the display substrate of this example can refer to the description of the previous embodiment, so it will not be repeated here.

The first connection line 31 or the second connection line 32 connected to the anode 141b of the first light-emitting element 14b can be located in the first transparent conductive layer, and the first connection line 31 or the second connection line 32 connected to the anode 141c of the first light-emitting element 14c can be located in the second transparent conductive layer.

[0202] In this example, the first and second connecting wires connecting the first light-emitting elements emitting different colors of light are arranged in different film layers, allowing for the rational arrangement of multiple first and second connecting wires. Furthermore, the first and second connecting wires in this example are made of transparent conductive material, which helps ensure light transmittance in the transmissive region. The remaining description of the display substrate in this example can be found in the description of the previous embodiment, and will not be repeated here.

Figure 11 only illustrates the connection relationship between several first light-emitting elements and first pixel circuits. In some examples, as shown in Figure 11, the island area A11 of the first display area A1 may include: a plurality of second light-emitting elements 15, a plurality of first pixel circuits 11 and a plurality of second pixel circuits 12; the transmission area TA may include: a plurality of first light-emitting elements 14. The first inter-island connection area A12a and the second inter-island connection area A12b connecting adjacent island areas A11 may be respectively provided with a plurality of signal lines. The plurality of first-region light-emitting elements in this example may include a plurality of first light-emitting elements 14 and a plurality of second light-emitting elements 15, and the plurality of first-region pixel circuits may include a plurality of first pixel circuits 11 and a plurality of second pixel circuits 12.

[0205] In some examples, at least one first pixel circuit 11 is connected to at least one first light-emitting element 14; and at least one second pixel circuit 12 is connected to at least one second light-emitting element 15. In this example, the first light-emitting element 14 and the second light-emitting element 15 can be driven by different pixel circuits, the first pixel circuit 11 is configured to drive the first light-emitting element 14, and the second pixel circuit 12 is configured to drive the second light-emitting element 15. For example, the first pixel circuit 11 and the first light-emitting element 14 can be connected in a one-to-one manner, and the second pixel circuit 12 and the second light-emitting element 15 can be connected in a one-to-one manner. However, this embodiment is not limited to this. In other examples, the first pixel circuit 11 and the first light-emitting element 14 can be connected in a one-to-many manner, or the second pixel circuit 12 and the second light-emitting element 15 can be connected in a one-to-many manner.

[0206] In some examples, a single island A11 may be provided with a pixel unit, which may include four second light-emitting elements 15 (e.g., one second light-emitting element 15a, one second light-emitting element 15b, and two second light-emitting elements 15c) and four second pixel circuits 12 (e.g., second pixel circuits 12a, 12b, 12c, and 12d). The second pixel circuit 12a may be electrically connected to one second light-emitting element 15a, the second pixel circuit 12b may be electrically connected to one second light-emitting element 15c, the second pixel circuit 12c may be electrically connected to another second light-emitting element 15c, and the second pixel circuit 12d may be electrically connected to one second light-emitting element 15b.

[0207] In some examples, the arrangement of the first pixel circuits 11 and the second pixel circuits 12 in the multiple island areas A11 can be the same. For example, the multiple first pixel circuits 11 and the multiple second pixel circuits 12 in the island area A11 can be arranged in rows. In some examples, the island area A11 may include four first pixel circuits 11 and four second pixel circuits 12, and the four second pixel circuits 12 can be arranged in a 2-row 2-column array, and the four first pixel circuits 11 can be arranged on both sides of the four second pixel circuits 12 along the first direction X. For example, in a row of pixel circuits, the order of one first pixel circuit 11, two second pixel circuits 12 and one first pixel circuit 11 can be arranged. However, this embodiment is not limited to this. In other examples, multiple (for example, four) first pixel circuits can be arranged in one row, and multiple (for example, four) second pixel circuits can be arranged in another row. In other examples, the plurality of second pixel circuits 12 in the island area A11 can be centrally arranged, and the plurality of first pixel circuits 11 can be arranged around the plurality of second pixel circuits 12; or, the plurality of first pixel circuits 11 and the plurality of second pixel circuits 12 in the island area A11 can be alternately arranged. In other examples, the arrangement of the pixel circuits in the plurality of island areas can be different, or partially the same.

[0208] In some examples, a single transmission area TA may be provided with a pixel unit, and the pixel unit may include four first light emitting elements 14. The four first light emitting elements 14 in the transmission area TA may be connected to the first pixel circuits 11 in different adjacent island areas A11.

[0209] In this example, the first-region pixel circuits and the first-region light-emitting elements within the first display region are electrically connected in a one-to-one correspondence, thereby ensuring the display quality and light transmittance of the first display region. The remaining description of the display substrate of this example can be found in the description of the previous embodiment and is not repeated here.

[0210] Figure 12 is another partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. Figure 12 only illustrates the connection relationship between several first light-emitting elements and second light-emitting elements. In some examples, as shown in Figure 12, the island area A11 of the first display area A1 may include: multiple second light-emitting elements 15, multiple first pixel circuits 11; the transmission area TA may include: multiple first light-emitting elements 14. The first inter-island connection area A12a and the second inter-island connection area A12b connecting adjacent island areas A11 can be respectively provided with multiple signal lines. The multiple first-region light-emitting elements in this example may include multiple first light-emitting elements 14 and multiple second light-emitting elements 15, and the multiple first-region pixel circuits may include multiple first pixel circuits 11.

[0211] In some examples, the first pixel circuit 11 can be connected to a first light-emitting element 14 and a second light-emitting element 15 emitting light of the same color, and configured to drive the connected first light-emitting element 14 and second light-emitting element 15 to emit light. For example, the anode of the first light-emitting element 14 can be connected to the anode of the second light-emitting element 15 emitting light of the same color in the adjacent island area A11 via a first connecting line 31, and the anode of the second light-emitting element 15 is connected to the first pixel circuit 11, thereby electrically connecting the first light-emitting element 14 and the second light-emitting element 15 emitting light of the same color to the same first pixel circuit 11. In this example, the first pixel circuit 11 is configured to simultaneously drive a second light-emitting element 15 in the island area A11 and a first light-emitting element 14 in the transmissive area TA, which helps to ensure the display effect of the first display area.

[0212] In some examples, the transmissive area TA may include a central region and an edge region. The edge region may surround the central region, and the edge region of the transmissive area TA may be adjacent to the island region A11 and the inter-island connection region. The first light-emitting element 14 may be located in the edge region of the transmissive area TA, and the first light-emitting element 14 may not be provided in the central region.

[0213] In this example, by disposing the first light-emitting element in a portion of the transmissive area TA, the pixel density of the first display area can be increased, and the light transmittance of the transmissive area can be guaranteed. The remaining description of the display substrate of this example can be referred to the description of the previous embodiment, so it will not be repeated here.

[0214] Figure 13 is another partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. Figure 13 only illustrates the connection relationship between several first light-emitting elements and first pixel circuits. In some examples, as shown in Figure 13, the island area A11 of the first display area A1 may include: multiple second light-emitting elements 15 and multiple second pixel circuits 12; the transmissive area TA may include: multiple first light-emitting elements 14; and the inter-island connection area may include: multiple first pixel circuits 11. The second pixel circuits 12 and second light-emitting elements 15 within a single island area A11 can be electrically connected one-to-one. At least one first pixel circuit 11 in the inter-island connection area can be electrically connected to multiple first light-emitting elements 14 in an adjacent transmissive area TA. For example, a first pixel circuit 11 in a first inter-island connection area A12a can drive multiple first light-emitting elements 14 in two adjacent transmissive areas TA in the second direction Y; and a first pixel circuit 11 in a second inter-island connection area A12b can drive multiple first light-emitting elements 14 in two adjacent transmissive areas TA in the first direction X. The plurality of first-region light-emitting elements in this example may include a plurality of first light-emitting elements 14 and a plurality of second light-emitting elements 15, and the plurality of first-region pixel circuits may include a plurality of first pixel circuits 11 and a plurality of second pixel circuits 12. In other examples, the first pixel circuits 11 located in the inter-island connection region and the first light-emitting elements 14 located in the transmission region TA may be connected in a one-to-one manner.

[0215] In some examples, as shown in FIG13 , a row of first pixel circuits 11 can be disposed within a single first inter-island connection region A12a. A row of first pixel circuits 11 within the first inter-island connection region A12a can be connected to multiple first light-emitting elements 14 within the upper and lower transmissive areas TA. A column of first pixel circuits 11 can be disposed within a single second inter-island connection region A12b. A column of first pixel circuits 11 within the second inter-island connection region A12b can be connected to multiple first light-emitting elements 14 within the left and right transmissive areas TA. A single first pixel circuit 11 can be connected to multiple first light-emitting elements 14 emitting the same color of light. By arranging the first pixel circuits within the inter-island connection region, this example can fully utilize the non-transmissive area within the first display area, thereby increasing the pixel density of the first display area. Furthermore, this arrangement in this example helps reduce the length of the first connecting wires 31 between the first pixel circuits 11 and the first light-emitting elements 14, thereby avoiding the increased load caused by excessively long connecting wires, which could affect the display quality.

[0216] In some examples, the transmissive area TA can be roughly rectangular with rounded corners. The edge between the transmissive area TA and the island area A11 can be an arc-shaped edge. In this example, adjacent edges of the transmissive area TA do not form a right-angled edge, which can reduce light diffraction and improve the display quality of the first display area. The remaining description of the display substrate of this example can be referred to the description of the previous embodiment, and will not be repeated here.

[0217] Figure 14 is another partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. Figure 14 only illustrates the connection relationship between several first light-emitting elements and first pixel circuits. In some examples, as shown in Figure 14, the multiple first-area light-emitting elements of this example may include: multiple first light-emitting elements 14 located in the transmission area TA and multiple second light-emitting elements 15 located in the island area A11. The multiple first-area pixel circuits may include multiple first pixel circuits 11 located in the inter-island connection area and multiple second pixel circuits 12 located in the island area A11.

[0218] In some examples, as shown in FIG14 , the number of rows and columns of the first pixel circuits 11 disposed in the inter-island connection region can be different from the number of rows and columns of the second pixel circuits 12 disposed in the island region A11. The number of rows of the second pixel circuits 12 in the island region A11 can be greater than the number of rows of the first pixel circuits 11 in the first inter-island connection region A12a; and the number of columns of the second pixel circuits 12 in the island region A11 can be greater than the number of columns of the first pixel circuits 11 in the second inter-island connection region A12b. A row of pixel circuits can include multiple pixel circuits arranged along a first direction X, and a column of pixel circuits can include multiple pixel circuits arranged along a second direction Y. However, this embodiment is not limited to this. In other examples, the number of rows of the second pixel circuits 12 in the island region A11 can be equal to the number of rows of the first pixel circuits 11 in the first inter-island connection region A12a; and the number of columns of the second pixel circuits 12 in the island region A11 can be equal to the number of columns of the first pixel circuits 11 in the second inter-island connection region A12b.

[0219] In some examples, as shown in FIG14 , a single first inter-island connection region A12a may be provided with a row of first pixel circuits 11. A single second inter-island connection region A12b may be provided with two columns of first pixel circuits 11. Numbered along the first direction X, the first column of first pixel circuits 11 may be connected to multiple first light-emitting elements 14 in the transmissive area TA adjacent to the left side of the second inter-island connection region A12b via first connection lines 31 and second connection lines 32. The second column of first pixel circuits 11 may be connected to multiple first light-emitting elements 14 in the transmissive area TA adjacent to the right side of the second inter-island connection region A12b via first connection lines 31 and second connection lines 32. In this example, the first pixel circuits 11 and the first light-emitting elements 14 may be connected in a one-drive-many manner. However, this embodiment is not limited to this. In other examples, the first pixel circuits 11 and the first light-emitting elements 14 may be connected in a one-drive-one manner. In still other examples, a single second inter-island connection region may be provided with a single column of first pixel circuits, and a single first inter-island connection region may be provided with multiple rows of first pixel circuits. This example does not limit the number of columns and rows of first pixel circuits within the inter-island connection region. A suitable number of first pixel circuits can be arranged based on the space provided in the inter-island connection region. The remaining description of the display substrate of this example can be found in the description of the previous embodiment and will not be repeated here.

Figure 16 is another partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. Figures 15 and 16 only illustrate the connection relationship between several first light-emitting elements and the first pixel circuit.

[0222] In some examples, as shown in FIG15 , the first inter-island connection region A12a may be provided with a row of first pixel circuits 11, and the second inter-island connection region A12b may be provided with a column of first pixel circuits 11. As shown in FIG16 , the first inter-island connection region A12a may be provided with a row of first pixel circuits 11, and the second inter-island connection region A12b may be provided with two columns of first pixel circuits 11.

[0223] In some examples, as shown in FIG15 , the transmissive area TA may be octagonal. The island area A11 may be roughly diamond-shaped. As shown in FIG16 , the transmissive area TA may be circular or elliptical, and the edge between the inter-island connecting area and the transmissive area TA may be an arcuate edge. This embodiment does not limit the shape of the transmissive area. In other examples, the transmissive area may be polygonal or irregular in shape. In this example, adjacent edges of the transmissive area TA are not connected to form right-angled edges, which can reduce light diffraction effects and improve the display quality of the first display area.

[0224] In some examples, as shown in Figures 15 and 16, a single first pixel circuit 11 in the first inter-island connection area A12a and the second inter-island connection area A12b can be connected to multiple first light-emitting elements 14 emitting the same color light in the adjacent transmission area TA.

A plurality of first region pixel circuits are arranged within the mesh region formed by the inter-island connection region and the island region A11. The arrangement of the second pixel circuits 12 within the island region A11 can be the same as the arrangement of the first pixel circuits 11 within the inter-island connection region. For example, a row of first pixel circuits 11 is provided in the first inter-island connection region A12a and aligned with a row of second pixel circuits 12 within the island region A11, and a column of first pixel circuits 11 is provided in the second inter-island connection region A12b and aligned with a column of second pixel circuits 12 within the island region A11.

[0234] In some examples, a plurality of second pixel circuits 12 can be connected to a plurality of second light-emitting elements 15. For example, the second pixel circuits 12 and the second light-emitting elements 15 can be connected in a one-to-one or one-to-many manner. A plurality of first pixel circuits 11 can be connected to a plurality of first light-emitting elements 14 and a plurality of third light-emitting elements 16. At least one first pixel circuit 11 can be connected to at least one first light-emitting element 14 and at least one third light-emitting element 16 that emit light of the same color. For example, one first pixel circuit 11 can be connected to one first light-emitting element 14 and one third light-emitting element 16 that emit light of the same color; or one first pixel circuit 11 can be connected to multiple first light-emitting elements 14 and one third light-emitting element 16 that emit light of the same color; or one first pixel circuit 11 can be connected to multiple first light-emitting elements 14 and multiple third light-emitting elements 16 that emit light of the same color; or one first pixel circuit 11 can be connected to one first light-emitting element 14 and multiple third light-emitting elements 16 that emit light of the same color. The first pixel circuit 11 in this example can also serve as a third pixel circuit to drive the first light-emitting element 14 and the third light-emitting element 16 .

[0235] In some examples, the orthographic projections of the third light-emitting element 16 and the first pixel circuit 11 to which it is connected on the substrate may at least partially overlap. The first light-emitting element 14 may be connected to the first pixel circuit 11 via a third connection line 33.

[0236] In some examples, the light emitting area of ​​the third light emitting element 16 can be smaller than the light emitting area of ​​the first light emitting element 14 emitting the same color light. In other examples, the light emitting area of ​​the third light emitting element 16 can be greater than or equal to the light emitting area of ​​the first light emitting element 14 emitting the same color light.

[0237] In some examples, the arrangement of the third light-emitting elements 16 in the inter-island connection region can be substantially the same as the arrangement of the first light-emitting elements 14 in the transmissive area TA. In other examples, the arrangement of the third light-emitting elements 16 in the inter-island connection region can be different from the arrangement of the first light-emitting elements 14 in the transmissive area TA. For example, the arrangement of the third light-emitting elements 16 in the inter-island connection region can be the same as the arrangement of the second light-emitting elements 15 in the island area A11.

[0238] In some examples, in the first direction X, the minimum distance between the second light-emitting elements 15 emitting the same color light within the island area A11 can be smaller than the minimum distance between the first light-emitting elements 14 emitting the same color light within the transmission area TA; and in the second direction Y, the minimum distance between the second light-emitting elements 15 emitting the same color light within the island area A11 can be smaller than the minimum distance between the first light-emitting elements 14 emitting the same color light within the transmission area TA. For example, the minimum distance between adjacent second light-emitting elements 15 emitting the first color light within the island area A11 in the first direction X can be smaller than the minimum distance between adjacent first light-emitting elements 14 emitting the first color light within the transmission area TA in the first direction X; and the minimum distance between adjacent second light-emitting elements 15 emitting the first color light within the island area A11 in the second direction Y can be smaller than the minimum distance between adjacent first light-emitting elements 14 emitting the first color light within the transmission area TA in the second direction Y. In this example, by increasing the minimum distance between first light-emitting elements emitting the same color light within the transmission area, the light transmittance of the transmission area can be improved.

[0239] In some examples, in the first direction X, the minimum distance between the third light-emitting elements 16 emitting the same color light (e.g., the first color light) in the first inter-island connecting area A12a can be less than or equal to the minimum distance between the first light-emitting elements 14 emitting the same color light (e.g., the first color light) in the transmissive area TA.

[0240] In some examples, in the first direction X, the minimum distance between the third light-emitting elements 16 emitting the same color light (e.g., the first color light) in the first inter-island connection region A12a can be greater than or equal to the minimum distance between the second light-emitting elements 15 emitting the same color light (e.g., the first color light) in the island region A11. In the second direction Y, the minimum distance between the third light-emitting elements 16 emitting the same color light (e.g., the first color light) in the second inter-island connection region A12b can be greater than or equal to the minimum distance between the second light-emitting elements 15 emitting the same color light (e.g., the first color light) in the island region A11. This embodiment is not limited to this.

[0271] Figure 27 is another partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. Figure 27 only illustrates the connection relationship between several first light-emitting elements and second light-emitting elements.

The edge setting of the island area and the inter-island connection area in this example can reduce the diffraction effect of light and enhance the display effect of the first display area. The rest of the description of the display substrate of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0272] Figure 28 is another partial schematic diagram of the first display area of ​​at least one embodiment of the present disclosure. In some examples, as shown in Figure 28 , the multiple first-area light-emitting elements of this example may include: multiple first light-emitting elements 14 located in the transmissive area TA, and multiple second light-emitting elements 15 located in the island area A11; the multiple first-area pixel circuits may include multiple second pixel circuits 12 located in the island area A11. In this example, the second pixel circuit 12 can also function as the first pixel circuit 11 to drive the first light-emitting elements 14 and the second light-emitting elements 15.

[0273] In some examples, as shown in FIG28 , the island A11 may include one pixel unit, which may include three second light-emitting elements 15 , for example, a second light-emitting element 15 a emitting a first color light, a second light-emitting element 15 b emitting a second color light, and a second light-emitting element 15 c emitting a third color light.

[0277] The display substrate of this example can increase the pixel density of the first display area by disposing the first light-emitting element in the transmission area, thereby achieving a high PPI display. The remaining description of the display substrate of this example can refer to the description of the previous embodiment, so it will not be repeated here.

[0278] FIG29 is an equivalent circuit diagram of a pixel circuit according to at least one embodiment of the present disclosure. The pixel circuit of this example is described using a 7T1C structure as an example. In some examples, as shown in FIG29 , the pixel circuit of this example may include seven transistors (i.e., a first transistor T1 to a seventh transistor T7) and a storage capacitor Cst. The light-emitting element EL may include an anode, a cathode, and an organic light-emitting layer disposed between the anode and the cathode.

[0279] In some examples, as shown in Figure 29, the pixel circuit can be connected to the first scan line GL1, the second scan line GL2, the third scan line GL3, the data line DL, the first power line VDD, the light emitting control line EML, the first initial signal line INIT1 and the second initial signal line INIT2; the light emitting element EL can be connected to the pixel circuit and the second power line VSS.

[0281] In some examples, the second scan line GL2 electrically connected to the pixel circuit in the nth row can be electrically connected to the first scan line GL1 electrically connected to the pixel circuit in the n-1th row, so as to be input with the first scan signal SCAN1(n-1), that is, the second scan signal SCAN2(n) and the first scan signal SCAN1(n-1) can be the same. The third scan line GL3 of the pixel circuit in the nth row can be electrically connected to the first scan line GL1 of the pixel circuit in the nth row, so as to be input with the first scan signal SCAN1(n), that is, the third scan signal SCAN3(n) and the first scan signal SCAN1(n) can be the same. Wherein, n is an integer greater than 0. In this way, the signal lines of the display substrate can be reduced, and a narrow frame design of the display substrate can be achieved. However, this embodiment is not limited to this.

[0282] In some examples, the first initial signal line INIT1 can be configured to provide a first initial signal to the pixel circuit, and the second initial signal line INIT2 can be configured to provide a second initial signal to the pixel circuit. In some examples, the first initial signal and the second initial signal line can be the same, and only the first initial signal line can be set to provide the first initial signal. However, this embodiment is not limited to this. In other examples, the first initial signal can be different from the second initial signal. The first initial signal and the second initial signal can be constant voltage signals, and their magnitudes can be, for example, between the first voltage signal and the second voltage signal, but are not limited thereto.

[0283] In some examples, as shown in FIG29 , the gate of the third transistor T3 is electrically connected to the first node N1, the first electrode of the third transistor T3 is electrically connected to the second node N2, and the second electrode of the third transistor T3 is electrically connected to the third node N3. The third transistor T3 may also be referred to as a drive transistor. The gate of the fourth transistor T4 is electrically connected to the first scan line GL1, the first electrode of the fourth transistor T4 is electrically connected to the data line DL, and the second electrode of the fourth transistor T4 is electrically connected to the first electrode of the third transistor T3. The fourth transistor T4 may also be referred to as a data write transistor. The gate of the second transistor T2 is electrically connected to the first scan line GL1, the first electrode of the second transistor T2 is electrically connected to the gate of the third transistor T3, and the second electrode of the second transistor T2 is electrically connected to the second electrode of the third transistor T3. The second transistor T2 may also be referred to as a threshold compensation transistor. The gate of the fifth transistor T5 is electrically connected to the emission control line EML, the first electrode of the fifth transistor T5 is electrically connected to the first power line VDD, and the second electrode of the fifth transistor T5 is electrically connected to the first electrode of the third transistor T3. The gate of the sixth transistor T6 is electrically connected to the emission control line EML, the first electrode of the sixth transistor T6 is electrically connected to the second electrode of the third transistor T3, and the second electrode of the sixth transistor T6 is electrically connected to the anode of the light-emitting element EL. The fifth transistor T5 and the sixth transistor T6 may also be referred to as emission control transistors. The first transistor T1 is electrically connected to the gate of the third transistor T3 and is configured to reset the gate of the third transistor T3. The seventh transistor T7 is electrically connected to the anode of the light-emitting element EL and is configured to reset the anode of the light-emitting element EL. The gate of the first transistor T1 is electrically connected to the second scan line GL2, the first electrode of the first transistor T1 is electrically connected to the first initial signal line INIT1, and the second electrode of the first transistor T1 is electrically connected to the gate of the third transistor T3. The gate of the seventh transistor T7 is electrically connected to the third scan line GL3, the first electrode of the seventh transistor T7 is electrically connected to the second initial signal line INIT2, and the second electrode of the seventh transistor T7 is electrically connected to the anode of the light-emitting element EL. The first transistor T1 and the seventh transistor T7 may also be referred to as reset control transistors. A first plate of the storage capacitor Cst is electrically connected to the gate of the third transistor T3 , and a second plate of the storage capacitor Cst is electrically connected to the first power line VDD.

[0284] In this example, the first node N1 is the connection point of the storage capacitor Cst, the first transistor T1, the third transistor T3 and the second transistor T2, the second node N2 is the connection point of the fifth transistor T5, the fourth transistor T4 and the third transistor T3, the third node N3 is the connection point of the third transistor T3, the second transistor T2 and the sixth transistor T6, and the fourth node N4 is the connection point of the sixth transistor T6, the seventh transistor T7 and the light-emitting element EL.

[0285] The operation process of the pixel circuit is described below. The pixel circuit shown in FIG29 includes a plurality of transistors, all of which are P-type transistors. In this example, the third scan signal provided by the third scan line GL3 may be the same as the first scan signal provided by the first scan line GL1.

[0286] In some examples, during a frame display period, the operation process of the pixel circuit may include: a first stage, a second stage, and a third stage.

[0287] The first phase is called the reset phase. The second scan signal SCAN2 provided by the second scan line GL2 can be a low-level signal, turning on the first transistor T1. The first initial signal provided by the first initial signal line INIT1 is provided to the first node N1, initializing the first node N1 and clearing the existing data voltage in the storage capacitor Cst. The first scan signal SCAN1 provided by the first scan line GL1 can be a high-level signal, and the emission control signal EM provided by the emission control line EML can be a high-level signal, turning off the fourth transistor T4, the second transistor T2, the fifth transistor T5, the sixth transistor T6, and the seventh transistor T7. During this phase, the light-emitting element EL does not emit light.

[0288] The second phase is called the data writing phase or the threshold compensation phase. The first scan signal SCAN1 provided by the first scan line GL1 can be a low-level signal, the second scan signal SCAN2 provided by the second scan line GL2, and the emission control signal EM provided by the emission control line EML can both be high-level signals, and the data line DL outputs the data signal DATA. During this phase, since the first plate of the storage capacitor Cst is at a low level, the third transistor T3 is turned on. The first scan signal SCAN1 is a low-level signal, turning on the second transistor T2, the fourth transistor T4, and the seventh transistor T7. The second transistor T2 and the fourth transistor T4 are turned on, causing the data voltage Vdata output by the data line DL to be provided to the first node N1 via the second node N2, the turned-on third transistor T3, the third node N3, and the turned-on second transistor T2. The difference between the data voltage Vdata output by the data line DL and the threshold voltage of the third transistor T3 is then charged into the storage capacitor Cst. The voltage on the first plate of the storage capacitor Cst (i.e., the first node N1) is Vdata - |Vth|, where Vdata is the data voltage output by the data line DL and Vth is the threshold voltage of the third transistor T3. The seventh transistor T7 is turned on, so that the second initialization signal provided by the second initialization signal line INIT2 is provided to the anode of the light-emitting element EL, initializing (resetting) the anode of the light-emitting element EL and clearing the pre-stored voltage therein, completing the initialization and ensuring that the light-emitting element EL does not emit light. The second scan signal SCAN2 provided by the second scan line GL2 can be a high-level signal, turning off the first transistor T1. The emission control signal EM provided by the emission control signal line EML is a high-level signal, turning off the fifth transistor T5 and the sixth transistor T6.

[0289] The third phase is called the light-emitting phase. The light-emitting control signal EM provided by the light-emitting control line EML is a low-level signal, while the first scan signal SCAN1 provided by the first scan line GL1 and the second scan signal SCAN2 provided by the second scan line GL2 are high-level signals. The light-emitting control signal EM provided by the light-emitting control line EML is a low-level signal, turning on the fifth transistor T5 and the sixth transistor T6. The first voltage signal output from the first power line VDD provides a driving voltage to the anode of the light-emitting element EL through the turned-on fifth transistor T5, third transistor T3, and sixth transistor T6, driving the light-emitting element EL to emit light.

[0290] During the pixel circuit driving process, the driving current flowing through the third transistor T3 is determined by the voltage difference between its gate and the first electrode. Since the voltage of the first node N1 is Vdata-|Vth|, the driving current of the third transistor T3 is: I=K×(Vgs-Vth) 2 =K×[(Vdd-Vdata+|Vth|)-Vth] 2=K×[Vdd-Vdata] 2 .

[0291] Wherein, I is the driving current flowing through the third transistor T3, that is, the driving current driving the light-emitting element EL, K is a constant, Vgs is the voltage difference between the gate and the first electrode of the third transistor T3, Vth is the threshold voltage of the third transistor T3, Vdata is the data voltage output by the data line DL, and Vdd is the first voltage signal output by the first power line VDD.

[0292] It can be seen from the above formula that the current flowing through the light emitting element EL has nothing to do with the threshold voltage of the third transistor T3. Therefore, the pixel circuit of this embodiment can better compensate for the threshold voltage of the third transistor T3.

[0293] The following uses the display substrate shown in Figure 28 as an example to illustrate the film structure of the display substrate through an example of the display substrate preparation process. The "patterning process" referred to in this disclosure includes processes such as coating photoresist, mask exposure, development, etching, and stripping photoresist for metal materials, inorganic materials, or transparent conductive materials. For organic materials, it includes processes such as coating organic materials, mask exposure, and development. Deposition can be achieved by any one or more of sputtering, evaporation, and chemical vapor deposition; coating can be achieved by any one or more of spraying, spin coating, and inkjet printing; and etching can be achieved by any one or more of dry etching and wet etching, which are not limited in this disclosure. A "thin film" refers to a thin film produced by deposition, coating, or other processes on a substrate using a certain material. If the "thin film" does not require a patterning process during the entire production process, the "thin film" can also be referred to as a "layer." If the "thin film" requires a patterning process during the entire production process, it is referred to as a "thin film" before the patterning process and a "layer" after the patterning process. The "layer" after the patterning process contains at least one "pattern."

[0294] The terms "A and B are arranged in the same layer" and "A and B are in the same layer structure" mentioned in the present disclosure mean that A and B are formed simultaneously through the same patterning process, or the surfaces of A and B close to the substrate are at substantially the same distance from the substrate, or the surfaces of A and B close to the substrate are in direct contact with the same film layer. The "thickness" of the film layer is the dimension of the film layer in the direction perpendicular to the display substrate. 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. The "shape of A" mentioned in the present disclosure refers to the shape of the orthographic projection of A on the substrate.

[0295] In some examples, the preparation process of the display substrate may include the following operations. The pixel circuit of the display area takes the 7T1C structure shown in Figure 29 as an example. The first pixel circuit of the island area A11 (also serving as the second pixel circuit) may include: a first transistor 51, a second transistor 52, a third transistor 53, a fourth transistor 54, a fifth transistor 55, a sixth transistor 56, a seventh transistor 57 and a storage capacitor; the second area pixel circuit of the second display area may include a first transistor 61, a second transistor 62, a third transistor 63, a fourth transistor 64, a fifth transistor 65, a sixth transistor 66, a seventh transistor 67 and a storage capacitor.

For example, the rigid substrate can be, but is not limited to, one or more of glass and quartz, and the flexible substrate can be, but is not limited to, one or more of polyethylene terephthalate, polyethylene terephthalate, polyetheretherketone, polystyrene, polycarbonate, polyarylate, polyarylate, polyimide, polyvinyl chloride, polyethylene, and textile fiber. In some examples, the flexible substrate can include a first flexible material layer, a first inorganic material layer, a second flexible material layer, and a second inorganic material layer stacked together. The materials of the first flexible material layer and the second flexible material layer can be polyimide (PI), polyethylene terephthalate (PET), or a surface-treated polymer soft film. The materials of the first inorganic material layer and the second inorganic material layer can be silicon nitride (SiNy, y>0) or silicon oxide (SiOx, x>0), etc., to improve the substrate's resistance to water and oxygen.

[0297] (2) Forming a semiconductor layer. In some examples, a buffer film and a semiconductor film are sequentially deposited on a substrate, and the semiconductor film is patterned by a patterning process to form a buffer layer disposed on the substrate and a semiconductor layer disposed on the buffer layer. In some examples, the semiconductor layer can be made of amorphous silicon (a-Si), polycrystalline silicon (p-Si), sexithiophene, or polythiophene.

[0298] Figure 30 is a partial schematic diagram of a semiconductor layer in a display region according to at least one embodiment of the present disclosure. Figure 30 shows a partial boundary region between the first display region A1 and the second display region. In some examples, as shown in FIG30 , the semiconductor layer of the display area may include at least: active layers of multiple transistors of multiple first pixel circuits (for example, three first pixel circuits are provided in each island area) located in the first display area A1 (for example, including: the active layer 510 of the first transistor of the first pixel circuit, the active layer 520 of the second transistor, the active layer 530 of the third transistor, the active layer 540 of the fourth transistor, the active layer 550 of the fifth transistor, the active layer 560 of the sixth transistor, and the active layer 570 of the seventh transistor), and active layers of multiple transistors of multiple second-area pixel circuits located in the second display area (for example, including: the active layer 610 of the first transistor, the active layer 620 of the second transistor, the active layer 630 of the third transistor, the active layer 640 of the fourth transistor, the active layer 650 of the fifth transistor, the active layer 660 of the sixth transistor, and the active layer 670 of the seventh transistor).

[0299] In some examples, the active layers of the first to seventh transistors of each first pixel circuit may be interconnected as an integrated structure. The active layers of the first to seventh transistors of each second region pixel circuit may be interconnected as an integrated structure.

[0300] In some examples, the active layer of each transistor may include: a first region, a second region, and a channel region located between the first region and the second region. The material of the semiconductor layer may include, for example, polysilicon. The channel region may not be doped with impurities and have semiconductor properties. The first region and the second region may be doped regions on both sides of the channel region, and are doped with impurities and therefore have conductivity. The impurities may vary depending on the type of transistor. In some examples, the doped region of the active layer may be interpreted as a source electrode or a drain electrode of the transistor. The portion of the active layer between the transistors may be interpreted as wiring doped with impurities, which can be used to electrically connect the transistors. This embodiment is not limited to this.

In some examples, a first gate insulating film and a first conductive film are sequentially deposited on the substrate having the aforementioned pattern formed thereon, and the first conductive film is patterned by a patterning process to form a first gate insulating layer disposed on the semiconductor layer and a first conductive layer disposed on the first gate insulating layer.

[0304] In some examples, two rows of second-region pixel circuits within the second display area can correspond to a row of first pixel circuits within the first display area A1. The first scan line GL1(n), the second scan line GL2(n), and the emission control line EML(n) can be connected to the second-region pixel circuits in the nth row; the first scan line GL1(n), the emission control line EML(n), and the first scan line GL1(n+1) can be connected to the first pixel circuits in the nth row, and the second scan line GL2(n+1) can be configured to be connected to the seventh transistor of the first pixel circuit in the nth row. The first scan line GL1(n+1) is connected to the second-region pixel circuits in the n+1th row and bypasses the first pixel circuits in the nth row on the side opposite to the second direction Y.

[0305] In some examples, the shape of the second scan line GL2(n) can be substantially a zigzag line extending along the first direction X.

An overlapping region of the second scan line GL2(n+1) and the active layer 570 of the seventh transistor 57 of the first pixel circuit in the n-th row can serve as a gate of the seventh transistor 57 .

[0309] In some examples, after forming the first conductive layer pattern, the first conductive layer can be used as a shield to conduct the semiconductor layer. The semiconductor layer in the area blocked by the first conductive layer forms the channel region of the transistor, and the semiconductor layer in the area not blocked by the first conductive layer can be conducted, that is, the first area and the second area of ​​the active layer can both be conducted.

[0343] In some examples, as shown in FIG37 , the pixel circuits within the island area A11 can be connected to a plurality of first signal lines extending along a first direction X and a plurality of second signal lines extending along a second direction Y. For example, the first signal lines connected to the pixel circuits in the i-th row of island areas may include: a first line L11a (e.g., an initial signal line), a second line L12a (e.g., a scan line), and a third line L13a (e.g., a light-emitting control line); the first signal lines connected to the pixel circuits in the i+1-th row of island areas may include: a first line L11b (e.g., an initial signal line), a second line L12b (e.g., a scan line), and a third line L13b (e.g., a light-emitting control line). The first line L11a, the second line L12a, and the third line L13a can extend substantially along the first direction X and be connected to the pixel circuits in the i-th row of island areas. The first, second, and third routing lines L11b, L12b, and L13b can be connected to the pixel circuits within the island region of the (i+1)th row and can bend in the second direction Y to bypass the transmissive area to ensure the size of the transmissive area.

In some examples, as shown in Figure 38, the display area may include a first display area A1, and the peripheral area BB may surround the first display area A1. The first display area A1 may include: a plurality of island areas A11 and a transmission area TA located between adjacent island areas A11. Each transmission area TA may include at least one first light-emitting element. The first pixel circuit driving the first light-emitting element may be located in the island area or in the inter-island connection area connecting adjacent island areas. Each island area A11 may include one or more pixel circuits. The display substrate of this example can increase light transmittance. The remaining description of the display substrate of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0346] Figure 39 is another schematic diagram of a display substrate according to at least one embodiment of the present disclosure. In some examples, as shown in Figure 39 , the display area may include a first display area A1, and a peripheral area BB may surround the first display area A1. The first display area A1 may include: multiple island areas A11 and transmissive areas located between adjacent island areas A11. The multiple transmissive areas may include at least one first transmissive area TA1 and at least one second transmissive area TA2. The first transmissive area TA1 may include at least one first light-emitting element; the second transmissive area TA2 may not include a first light-emitting element. Each island area A11 may include one or more pixel circuits.

[0347] In some examples, the first transmission areas TA1 and the second transmission areas TA2 may be arranged alternately or in an array. For example, in the second direction Y, a row of first transmission areas TA1 and a row of second transmission areas TA2 may be arranged alternately. This embodiment is not limited to this. The display substrate of this embodiment can increase light transmittance. The remaining description of the display substrate of this embodiment can refer to the description of the previous embodiment and is not repeated here.

[0348] This embodiment also provides a display substrate, comprising a first display area, the first display area comprising: a plurality of island regions separated from each other, an inter-island connection region connecting adjacent island regions, and a plurality of transmissive regions surrounded by the plurality of island regions and the inter-island connection region. The transmissive regions have a greater light transmittance than the island regions and the inter-island connection region. The inter-island connection region comprises: at least one third light-emitting element disposed on the substrate, the at least one third light-emitting element being electrically connected to at least one third pixel circuit. The at least one third pixel circuit is located in the island region or in the inter-island connection region.

[0349] In some examples, the third pixel circuit and the third light-emitting element located in the inter-island connection region can be connected in a one-to-one or one-to-many manner. For example, the third pixel circuit and the third light-emitting element can be connected in a one-to-one correspondence; or, one third pixel circuit can be electrically connected to multiple third light-emitting elements, for example, one third pixel circuit can be electrically connected to multiple third light-emitting elements that emit light of the same color. This embodiment is not limited to this.

[0350] The display substrate provided in this embodiment sets a third light-emitting element in the inter-island connection area, and sets a third pixel circuit for driving the third light-emitting element in the island area or the inter-island connection area. This can increase the pixel density of the first display area while ensuring the light transmittance of the first display area, thereby achieving high PPI display.

[0351] In some exemplary embodiments, the first display area may further include at least one second light-emitting element disposed on the substrate and located in the island region. A third pixel circuit in the island region is electrically connected to the at least one second light-emitting element emitting light of the same color and to the at least one third light-emitting element located in the inter-island connection region. In this example, the second and third light-emitting elements emitting light of the same color can be driven by the same pixel circuit, which can reduce the number of pixel circuits and thereby improve light transmittance in the first display area.

[0352] In some exemplary embodiments, the first display area may further include: at least one second light-emitting element and at least one second pixel circuit disposed on the substrate and located in the island region. The at least one second pixel circuit is electrically connected to the at least one second light-emitting element, and the orthographic projection of the second pixel circuit and the connected second light-emitting element on the substrate may at least partially overlap. In this example, the second and third light-emitting elements may be driven by different pixel circuits, which helps ensure the display quality of the first display area.

[0353] In some exemplary embodiments, the inter-island connection area of ​​the first display area may include: a first inter-island connection area and a second inter-island connection area. The first inter-island connection area connects adjacent island areas along a first direction, and the second inter-island connection area connects adjacent island areas along a second direction, and the first direction intersects the second direction. For example, the first direction may be perpendicular to the second direction. The number of pixel circuit rows in the first inter-island connection area is less than or equal to the number of pixel circuit rows in the island area; the number of pixel circuit columns in the second inter-island connection area is less than or equal to the number of pixel circuit columns in the island area. Among them, the multiple pixel circuits arranged along the first direction are a row of pixel circuits, and the multiple pixel circuits arranged along the second direction are a column of pixel circuits. This example can make full use of the space of the inter-island connection area to arrange pixel circuits.

[0354] In some exemplary embodiments, the transmissive region may include: at least one first light-emitting element disposed on a substrate; the at least one first light-emitting element being electrically connected to at least one third pixel circuit. The first inter-island connection region includes a row of pixel circuits, wherein the third pixel circuits within the row of pixel circuits are connected to a plurality of first light-emitting elements emitting the same color light in two adjacent transmissive regions of the first inter-island connection region in the second direction. The second inter-island connection region includes a column of pixel circuits, wherein the third pixel circuits within the column of pixel circuits are connected to a plurality of first light-emitting elements emitting the same color light in two adjacent transmissive regions of the second inter-island connection region in the first direction. The configuration of this example allows the first and third light-emitting elements to share a pixel circuit, and can also reduce the length of the connecting line between the first pixel circuit and the first light-emitting element, thereby avoiding the situation where the display effect is affected by the large load caused by the long connecting line.

[0355] In some exemplary embodiments, the light-emitting area of ​​the first light-emitting element can be smaller than the light-emitting area of ​​the second light-emitting element emitting light of the same color; and the light-emitting area of ​​the third light-emitting element can be smaller than or equal to the light-emitting area of ​​the second light-emitting element emitting light of the same color. This arrangement helps ensure the light transmittance and display quality of the first display area.

[0356] The rest of the description about the display substrate of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0357] This embodiment also provides a display substrate, comprising: a first display area; the first display area comprising: a plurality of island areas separated from each other, an inter-island connection area connecting adjacent island areas, and a plurality of transmission areas surrounded by the plurality of island areas and the inter-island connection area. The light transmittance of the transmission area is greater than the light transmittance of the island areas and the inter-island connection area. The transmission area comprises: at least one first light-emitting element disposed on a substrate. The inter-island connection area comprises: at least one first pixel circuit disposed on a substrate; the at least one first light-emitting element in the transmission area is electrically connected to at least one first pixel circuit in an adjacent inter-island connection area, and the distance between the first pixel circuit and the orthographic projection of the connected first light-emitting element on the substrate is greater than zero. In other words, the orthographic projection of the first pixel circuit and the connected first light-emitting element on the substrate does not overlap.

[0358] In some exemplary embodiments, the transmissive region includes multiple first light-emitting elements emitting light of different colors; the first light-emitting elements emitting light of different colors within the transmissive region are located on different insulating layers, while the first light-emitting elements emitting light of the same color within the transmissive region are located on the same insulating layer; or, the multiple first light-emitting elements within the transmissive region are located on the same insulating layer. In this example, adjusting the insulating layer below the first light-emitting elements can help improve the light transmittance of the transmissive region.

[0359] In some exemplary embodiments, the first pixel circuit in the inter-island connection region is connected to the at least one first light-emitting element in the adjacent transmission region through at least one connection line; the at least one connection line is made of metal material or transparent conductive material.

[0360] In some exemplary embodiments, the inter-island connection region further includes: at least one third light-emitting element disposed on the substrate; and the at least one first pixel circuit in the inter-island connection region is electrically connected to the at least one first light-emitting element in the transmission region and the at least one third light-emitting element in the inter-island connection region, both of which emit light of the same color. In this example, the first and third light-emitting elements share the first pixel circuit, which reduces the space occupied by the pixel circuit and improves light transmittance in the first display area.

[0361] In some exemplary embodiments, the inter-island connection region further includes: at least one third light-emitting element and at least one third pixel circuit disposed on the substrate, the at least one third pixel circuit being electrically connected to the at least one third light-emitting element, with the third pixel circuit and the connected third light-emitting element at least partially overlapping with their orthographic projections on the substrate. In this example, the first and third light-emitting elements are independently driven by different pixel circuits, ensuring a good display quality.
