[0079] Detailed Explanation

[0080] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Note that the implementation methods can be carried out in many different forms. Those skilled in the art will readily understand that the methods and content can be transformed into various forms without departing from the spirit and scope of this disclosure. Therefore, this disclosure should not be construed as limited to the content described in the following embodiments. Without conflict, the embodiments and features in the embodiments of this disclosure can be arbitrarily combined with each other. To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of some known functions and components have been omitted. The accompanying drawings of the embodiments of this disclosure only relate to the structures involved in the embodiments of this disclosure; other structures can be referred to with reference to general designs.

[0081] The scale of the figures in this disclosure can be used as a reference in actual manufacturing processes, but is not limited thereto. For example, the aspect ratio of the channel, the thickness and spacing of each film layer, and the width and spacing of each signal line can be adjusted according to actual needs. The number of pixels in the display substrate and the number of sub-pixels in each pixel are not limited to the quantities shown in the figures. The figures described in this disclosure are only schematic diagrams of the structure, and one aspect of this disclosure is not limited to the shapes or values ​​shown in the figures.

[0082] The ordinal numbers “first,” “second,” and “third” used in this specification are used to avoid confusion among the constituent elements, not to limit their quantity.

[0083] In this specification, for convenience, terms such as "middle," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships in conjunction with the accompanying drawings. This is solely for the purpose of facilitating the description and simplification, and does not imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this disclosure. The positional relationships of the constituent elements may be appropriately varied depending on the orientation of each constituent element being described. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0084] In this specification, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection, an indirect connection via an intermediate component, or a connection within two components. Those skilled in the art will understand the specific meaning of these terms in this disclosure based on the specific circumstances.

[0085] In this specification, a transistor is a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between the drain electrode (drain electrode terminal, drain region, or drain electrode) and the source electrode (source electrode terminal, source region, or source electrode), and current can flow through the drain electrode, the channel region, and the source electrode. Note that in this specification, the channel region refers to the region through which current primarily flows.

[0086] In this specification, the first electrode can be the drain electrode and the second electrode can be the source electrode, or vice versa. In cases where transistors with opposite polarities are used or the current direction changes during circuit operation, the functions of the "source electrode" and "drain electrode" may sometimes be interchanged. Therefore, in this specification, the "source electrode" and "drain electrode" can be interchanged.

[0087] In this specification, "electrical connection" includes the situation where components are connected together by elements that have a certain electrical function. There are no particular limitations on what constitutes an "electrical function," as long as it allows for the transmission and reception of electrical signals between the connected components. Examples of "electrical functions" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements with various functions.

[0088] In this specification, "parallel" refers to the state where the angle formed by two straight lines is greater than or equal to -10° and less than 10°, and therefore also includes the state where the angle is greater than or equal to -5° and less than 5°. Similarly, "perpendicular" refers to the state where the angle formed by two straight lines is greater than or equal to 80° and less than 100°, and therefore also includes the state where the angle is greater than or equal to 85° and less than 95°.

[0089] In this disclosure, "A extends along direction B" means that A may include a main part and a secondary part connected to the main part. The main part is a line, line segment, or strip-shaped body. The main part extends along direction B, and the length of the main part extending along direction B is greater than the length of the secondary part extending along other directions. In the following description, "A extends along direction B" refers to "the main body of A extends along direction B".

[0090] In this specification, the terms "film" and "layer" may be interchanged. For example, "conductive layer" may sometimes be replaced with "conductive film." Similarly, "insulating film" may sometimes be replaced with "insulating layer."

[0091] In this specification, the term "same-layer arrangement" refers to a structure formed by patterning two (or more) structures through the same patterning process, and their materials may be the same or different. For example, the precursors forming multiple structures in a same-layer arrangement may be made of the same material, while the final materials may be the same or different.

[0092] In this specification, triangles, rectangles, trapezoids, pentagons, or hexagons are not strictly defined; they can be approximate triangles, rectangles, trapezoids, pentagons, or hexagons. Small deformations due to tolerances are possible, as are chamfers, curved edges, and other variations.

[0093] In this disclosure, “about” means a value that is not strictly limited and allows for process and measurement errors.

[0094] Figure 1 is a schematic diagram of a display device. As shown in Figure 1, the display device may include: a timing controller, a data driver, a scan driver, a light-emitting driver, and a pixel array. The timing controller is connected to the data driver, the scan driver, and the light-emitting driver. The data driver is connected to multiple data signal lines (e.g., D1 to Dn), the scan driver is connected to multiple scan signal lines (e.g., S1 to Sm), and the light-emitting driver is connected to multiple light-emitting signal lines (e.g., E1 to Eo). Here, n, m, and o can be natural numbers. The pixel array may include multiple sub-pixels Pxij, where i and j can be natural numbers. At least one sub-pixel Pxij may include: a pixel driving circuit and a light-emitting device connected to the pixel driving circuit. The pixel driving circuit may include at least a pixel driving circuit, which may be connected to the scan signal lines, the light-emitting signal lines, and the data signal lines respectively.

[0095] In an exemplary embodiment, the timing controller can provide grayscale values ​​and control signals suitable for the specifications of the data driver to the data driver, clock signals, scan start signals, etc. suitable for the specifications of the scan driver to the scan driver, and clock signals, transmit stop signals, etc. suitable for the specifications of the light-emitting driver to the light-emitting driver. The data driver can use the grayscale values ​​and control signals received from the timing controller to generate data voltages to be provided to data signal lines D1, D2, D3, ..., Dn. For example, the data driver can sample grayscale values ​​using a clock signal and apply data voltages corresponding to grayscale values ​​to data signal lines D1 to Dn on a pixel-by-pixel basis. The scan driver can generate scan signals to be provided to scan signal lines S1, S2, S3, ..., Sm by receiving clock signals, scan start signals, etc. from the timing controller. For example, the scan driver can sequentially provide scan signals with on-level pulses to scan signal lines S1 to Sm. For example, a scan driver can be configured as a shift register and can generate scan signals by sequentially transmitting scan start signals, provided in the form of on-level pulses, to the next stage circuit under the control of a clock signal. An LED driver can generate LED control signals to be provided to LED signal lines E1, E2, E3, ..., Eo by receiving clock signals, transmit stop signals, etc., from a timing controller. For example, an LED driver can sequentially provide transmit signals with off-level pulses to LED signal lines E1 to Eo. For example, an LED driver can be configured as a shift register and can generate LED control signals by sequentially transmitting transmit stop signals, provided in the form of off-level pulses, to the next stage circuit under the control of a clock signal.

[0096] Figure 2 is a schematic diagram of a display substrate. As shown in Figure 2, the display substrate may include a display area AA, a bonding area CC located on one side of the display area AA, and a border area BB located on the other sides of the display area AA.

[0097] In an exemplary embodiment, the display area AA may be a flat area comprising a plurality of sub-pixels Pxij that make up the pixel array. The plurality of sub-pixels Pxij may be configured to display moving or still images, and the display area AA may be referred to as the effective area (AA). In some examples, the display substrate may be a flexible substrate, and thus, the display substrate may be deformable, such as being rolled up, bent, folded, or rolled up.

[0098] In an exemplary embodiment, the bonding area may include a lead area, a bending area, and a composite circuit area arranged sequentially along a direction away from the display area, with the lead area connected to the display area, the bending area connected to the lead area, and the composite circuit area connected to the bending area.

[0099] In an exemplary embodiment, the lead area can be provided with multiple leads. One end of the multiple leads is connected to multiple data signal lines in the display area, and the other end of the multiple leads crosses the bend area and connects to the integrated circuit in the composite circuit area, so that the integrated circuit applies data signal lines through the leads.

[0100] In an exemplary embodiment, the bending area can be bent with a curvature, which can reverse the surface of the composite circuit area. That is, the upward-facing surface of the composite circuit area can be transformed into a downward-facing surface by bending the bending area, with the third direction intersecting the first direction. In an exemplary embodiment, when the bending area is bent, the composite circuit area can overlap with the display area in the thickness direction.

[0101] In an exemplary embodiment, the composite circuit region may include an anti-static region, a driver chip region, and a bonding pin region. An integrated circuit (IC) may be bonded to the driver chip region, and a flexible printed circuit (FPC) may be bonded to the bonding pin region. In an exemplary embodiment, the integrated circuit can generate driving signals required to drive sub-pixels and can provide these driving signals to the sub-pixels in the display area. For example, the driving signal may be a data signal that drives the brightness of the sub-pixels. In an exemplary embodiment, the integrated circuit may be bonded to the driver chip region via an anisotropic conductive film or other means. The width of the integrated circuit in the second direction may be smaller than the width of the composite circuit region in the second direction, and the second direction intersects the first direction. In an exemplary embodiment, the bonding pin region may be provided with pads including multiple pins, and the flexible printed circuit board may be bonded to the pads.

The cutting region, connected to the crack dam region, may include at least a cutting groove formed on the composite insulating layer, configured such that after all film layers of the display substrate have been prepared, a cutting device cuts along the cutting grooves respectively.

[0103] The display area may include multiple pixel units arranged in a matrix. At least one pixel unit may include a first sub-pixel emitting a first color light, a second sub-pixel emitting a second color light, and a third and fourth sub-pixels emitting a third color light. Each sub-pixel may include a circuit unit and a light-emitting device. The circuit unit may include at least a pixel driving circuit, which is connected to a scan signal line, a data signal line, and a light-emitting signal line, respectively. The pixel driving circuit may be configured to receive the data voltage transmitted by the data signal line under the control of the scan signal line and the light-emitting signal line, and output a corresponding current to the light-emitting device, thereby driving the light-emitting device to emit light. The light-emitting device in each sub-pixel is connected to the pixel driving circuit of its respective sub-pixel, and the light-emitting device is configured to emit light of a corresponding brightness in response to the current output by the pixel driving circuit of its respective sub-pixel.

[0104] In an exemplary embodiment, at least one pixel driving circuit may be electrically connected to at least one light-emitting device.

[0105] In an exemplary embodiment, the first sub-pixel P1 may be a red sub-pixel (R) that emits red light, the second sub-pixel P2 may be a blue sub-pixel (B) that emits blue light, and the third sub-pixel P3 and the fourth sub-pixel P4 may be green sub-pixels (G) that emit green light.

[0106] In some examples, the shape of the light-emitting area of ​​the light-emitting device of at least one sub-pixel can be rectangular, rhomboid, pentagonal, or hexagonal.

[0107] In an exemplary embodiment, the pixel driving circuit may include a plurality of transistors and at least one capacitor. For example, the pixel driving circuit may be a 3T1C (3 transistors and 1 capacitor) structure, a 5T1C (5 transistors and 1 capacitor) structure, a 7T1C (7 transistors and 1 capacitor) structure, or an 8T1C (8 transistors and 1 capacitor) structure.

[0108] In an exemplary embodiment, the light-emitting device can be an organic light-emitting diode (OLED), which emits red, green, blue, or white light under the drive of its corresponding pixel driving circuit. The emitted color of the light-emitting device can be determined as needed. The light-emitting device 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 device can be electrically connected to the corresponding pixel driving circuit. However, this embodiment is not limited in this respect.

[0109] Figure 3 is an equivalent circuit diagram of a pixel driving circuit. Figure 3 illustrates the pixel driving circuit with a 7T1C structure as an example. As shown in Figure 3, at least one pixel driving circuit is electrically connected to the scan signal line Gate, the first reset signal line Reset1, the second reset signal line Reset2, the data signal line Data, the light emission signal line EM, the first initial signal line INIT1, the second initial signal line INIT2, and the first power supply line VDD, respectively. The light emission device L is electrically connected to the pixel driving circuit and the second power supply line VSS, respectively. In some examples, the first power supply line VDD is configured to provide a constant first power signal to the pixel driving circuit, which is a positive voltage signal, and the second power supply line VSS is configured to provide a constant second power signal to the pixel driving circuit, which is a negative voltage signal. The scan signal line Gate is configured to provide a scan signal to the pixel driving circuit. The first reset signal line Reset1 is configured to provide a first reset signal to the pixel driving circuit. The second reset signal line Reset2 is configured to provide a second reset signal to the pixel driving circuit. The data signal line Data is configured to provide a data signal to the pixel driving circuit. The light emission signal line EM is configured to provide a light emission control signal to the pixel driving circuit. The first initial signal line INIT1 is configured to provide a first initial signal to the pixel driving circuit. The second initial signal line INIT2 is configured to provide a second initial signal to the pixel driving circuit.

[0110] In some examples, the signal received by the second reset signal line connected to at least one row of pixel driving circuits is the same as the signal received by the scan signal line connected to at least one row of pixel driving circuits, and the signal received by the first reset signal line connected to at least one row of pixel driving circuits is the same as the signal received by the scan signal line connected to at least one row of pixel driving circuits. For example, the signal received by the second reset signal line connected to the nth row of pixel driving circuits is the same as the signal received by the scan signal line connected to the (n-1)th row of pixel driving circuits, and the signal received by the first reset signal line connected to the nth row of pixel driving circuits is the same as the signal received by the scan signal line connected to the (n-2)th row of pixel driving circuits. Since the signal received by at least one of the first and second reset signal lines connected to at least one row of pixel driving circuits is the same as the signal received by the scan signal line connected to at least one row of pixel driving circuits, the scan driver located in the bezel area can include: a gate driving circuit, which is electrically connected to the first reset signal line, the second reset signal line, and the scan signal line connected to the at least one row of pixel driving circuits, respectively. This reduces the area occupied by the circuit area and improves the resolution of the display substrate. Resolution (Pixels Per Inch, or PPI for short) refers to the number of pixels per unit area, also known as pixel density. The higher the PPI value, the higher the density at which the display substrate can display the image, and the richer the details of the image.

[0111] In some examples, the signal received by the first reset signal line connected to the n+1 row pixel driving circuit is the same as the signal received by the second reset signal line connected to the nth row pixel driving circuit. That is, the first reset signal line connected to the n+1 row pixel driving circuit and the second reset signal line connected to the nth row pixel driving circuit can be the same signal. In this way, the number of signal lines of the display substrate can be reduced, and a high PPI of the display substrate can be achieved.

[0112] In some examples, the signal received by the first initial signal line connected to the nth row pixel driving circuit is the same as the signal received by the second initial signal line connected to the nth row pixel driving circuit. That is, the first initial signal line connected to the nth row pixel driving circuit and the second initial signal line connected to the nth row pixel driving circuit can be the same signal. In this way, the number of signal lines of the display substrate can be reduced, and a high PPI of the display substrate can be achieved.

[0113] In an exemplary embodiment, as shown in FIG3, at least one pixel driving circuit includes: a first transistor T1 to a seventh transistor T7 and a capacitor C, wherein the capacitor C includes: a first plate and a second plate. The control electrode of the first transistor T1 is electrically connected to the first reset signal line Reset1, 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 fifth node N5. The control electrode of the second transistor T2 is electrically connected to the scan signal line Gate, the first electrode of the second transistor T2 is electrically connected to the first node N1, and the second electrode of the second transistor T2 is electrically connected to the third node N3. The control electrode 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 control electrode of the fourth transistor T4 is electrically connected to the scan signal line Gate, the first electrode of the fourth transistor T4 is electrically connected to the data signal line Data, and the second electrode of the fourth transistor T4 is electrically connected to the second node N2. The control electrode of the fifth transistor T5 is electrically connected to the light-emitting signal line EM, the first electrode of the fifth transistor T5 is electrically connected to the first power supply line VDD, and the second electrode of the fifth transistor T5 is electrically connected to the second node N2. The control electrode of the sixth transistor T6 is electrically connected to the light-emitting signal line EM, the first electrode of the sixth transistor T6 is electrically connected to the third node N3, and the second electrode of the sixth transistor T6 is electrically connected to the fourth node N4. The control electrode of the seventh transistor T7 is electrically connected to the second reset signal line Reset2, 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 fourth node N4. The first plate of capacitor C is electrically connected to the first node N1, and the second plate of capacitor C is electrically connected to the first power supply line VDD.

[0114] In this disclosure, the first node N1 is the connection point of capacitor C, first transistor T1, second transistor T2 and third transistor T3. Specifically, the first node N1 is the connection point of the first plate of capacitor C, the second electrode of first transistor T1, the first electrode of second transistor T2 and the control electrode of third transistor T3.

[0115] In this disclosure, the second node N2 is the connection point of the third transistor T3, the fourth transistor T4 and the fifth transistor T5. Specifically, the second node N2 is the connection point of the first terminal of the third transistor, the second terminal of the fourth transistor T4 and the second terminal of the fifth transistor T5.

[0116] In this disclosure, the third node N3 is the connection point of the second transistor T2, the third transistor T3 and the sixth transistor T6. Specifically, the third node N3 is the connection point of the second terminal of the second transistor T2, the second terminal of the third transistor T3 and the first terminal of the sixth transistor T6.

[0117] In this disclosure, the fourth node N4 is the connection point of the sixth transistor T6, the seventh transistor T7, and the light-emitting device L. Specifically, the fourth node N4 is the connection point of the second electrode of the sixth transistor T6, the second electrode of the seventh transistor T7, and the anode of the light-emitting device L.

[0118] Based on their characteristics, transistors can be classified into N-type transistors and P-type transistors. When a transistor is P-type, its turn-on voltage is a low-level voltage (e.g., 0V, -5V, -10V, or other suitable voltage), and its turn-off voltage is a high-level voltage (e.g., 5V, 10V, or other suitable voltage). When a transistor is N-type, its turn-on voltage is a high-level voltage (e.g., 5V, 10V, or other suitable voltage), and its turn-off voltage is a low-level voltage (e.g., 0V, -5V, -10V, or other suitable voltage).

[0119] In an exemplary embodiment, the first transistor T1 to the seventh transistor T7 can be either P-type transistors or N-type transistors. Using the same type of transistor in the pixel driving circuit can simplify the process flow, reduce the processing difficulty of the display substrate, and improve the product yield. In some possible implementations, the first transistor T1 to the seventh transistor T7 may include both P-type and N-type transistors.

[0120] In an exemplary embodiment, the seven transistors of the pixel driving circuit can be low-temperature polysilicon (LTPS) thin-film transistors (TFTs), oxide thin-film transistors (OPTs), or a combination of both. The active layer of the LTPS TFT is made of low-temperature polysilicon (LTPS), while the active layer of the OPT TFT is made of oxide. LTPS TFTs offer advantages such as high mobility and fast charging, while OPTs offer advantages such as low leakage current. Integrating LTPS and OPTs onto a single display substrate, i.e., an LTPS+Oxide (LTPO) display substrate, leverages the advantages of both, enabling low-frequency driving, reducing power consumption, and improving display quality.

[0121] Figure 4 is a timing diagram of the pixel driving circuit shown in Figure 3. The operation of the pixel driving circuit shown in Figure 3 will be described below with reference to Figure 4. In the figure, the first transistor T1 to the seventh transistor T7 of the pixel driving circuit are P-type transistors.

[0122] In some exemplary embodiments, as shown in Figures 3 and 4, the operation of the pixel driving circuit during a frame display time period may include: a first stage P1, a second stage P2, a third stage P3, and a fourth stage P4.

[0123] In the first stage P1, also known as the first reset stage, the signal on the first reset signal line Reset1 is low, while the signals on the scan signal line Gate, the second reset signal line Reset2, and the light emission signal line EM are high. The first transistor T1 is turned on, while the second transistor T2, the fourth transistor T4, the fifth transistor T5, the sixth transistor T6, and the seventh transistor T7 are turned off.

[0124] The first transistor T1 is turned on, and the first initial signal provided by the first initial signal line INIT1 is provided to the first node N1 to initialize the first node N1, clear its internal pre-stored voltage, and complete the initialization.

[0125] In the second stage (P2), the second reset stage, the signal on the second reset signal line Reset2 is low, while the signals on the scan signal line Gate, the first reset signal line Reset1, and the light emission signal line EM are high. The seventh transistor T7 is turned on, while the first transistor T1, the second transistor T2, the fourth transistor T4, the fifth transistor T5, and the sixth transistor T6 are turned off.

[0126] The seventh transistor T7 is turned on, so that the second initial signal provided by the second initial signal line INIT2 is provided to the fourth node N4 to initialize (reset) the anode of the light-emitting device L, clear its internal pre-stored voltage, complete the initialization, and ensure that the light-emitting device L does not emit light.

[0127] The third stage, P3, is called the data writing stage or threshold compensation stage. The Gate signal is low, while the Reset1, Reset2, and EM signals are high. The Data signal line outputs the data signal. The second transistor T2 and the fourth transistor T4 are turned on, while the first transistor T1, the fifth transistor T5, the sixth transistor T6, and the seventh transistor T7 are turned off.

[0128] The second transistor T2 and the fourth transistor T4 are turned on. The data signal output from the data signal line Data is provided to the first node N1 through the turned-on fourth transistor T4, the turned-on third transistor T3, and the turned-on second transistor T2, until the signal at the first node satisfies Vdata-|Vth|, where Vdata is the voltage value of the data signal output from the data signal line Data, and Vth is the threshold voltage of the third transistor T3.

[0129] The fourth stage, P4, is called the light-emitting stage. The light-emitting signal line EM is a low-level signal, while the first reset signal line Reset1, the second reset signal line Reset2, and the scan signal line Gate are high-level signals. The fifth transistor T5 and the sixth transistor T6 are turned on, while the first transistor T1, the second transistor T2, the fourth transistor T4, and the seventh transistor T7 are turned off.

[0130] When the fifth transistor T5 and the sixth transistor T6 are turned on, the power signal output from the first power line VDD provides a driving voltage to the fourth node N4 (which is the anode of the light-emitting device L) through the turned-on fifth transistor T5, third transistor T3 and sixth transistor T6, driving the light-emitting device L to emit light.

[0131] During the pixel driving circuit's operation, the driving current flowing through the third transistor T3 is determined by the voltage difference between its control electrode and its first electrode. Since the voltage at 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

[0132] Where I is the driving current flowing through the third transistor T3, which is the driving current driving the light-emitting device, K is a constant, Vgs is the voltage difference between the control electrode and the first electrode of the third transistor T3, and Vdd is the voltage value of the power signal output by the first power line VDD.

[0133] The concept of full-screen phones has garnered widespread attention in the mobile phone market and represents the future direction of mobile phone development. Full-screen phones employ a Full Display with Camera (FDC) structure, where the camera area is also displayed. This FDC structure allows the almost entirely visible front area to be screen, providing users with a superior display experience.

[0134] With the development of OLED display technology, consumers have increasingly higher demands for display effects, and ultra-narrow bezels have become a new trend in display product development. Therefore, narrow bezels and even bezel-less designs are receiving increasing attention in OLED display product design. To achieve narrow bezels, the display substrate employs a Fanout-in-Panel (FIP) structure, where one end of multiple data adapters connects to multiple data signal lines in the display area, and the other end extends to the bonding area, connecting to the integrated circuits in the bonding area. Since the bonding area does not require fan-shaped diagonal lines, the width of the fan-out area is reduced, effectively decreasing the width of the bottom bezel.

[0135] The load between at least one data transfer line in the display substrate and the active pattern of at least one transistor (e.g., the active pattern of the second transistor, the active pattern of the third transistor, and the active pattern of the sixth transistor) is large, which causes the voltage value of the first node in at least one pixel driving circuit to decrease. This results in a larger driving voltage output by at least one pixel driving circuit, leading to higher brightness in some areas of the display substrate. This reduces the brightness uniformity of the display substrate and affects the display effect of the display substrate.

[0136] Therefore, this disclosure provides a display substrate that can improve the brightness uniformity of the display substrate and enhance the display effect of the display substrate.

The at least one transistor includes an active pattern, a control electrode, a first electrode, and a second electrode. The capacitor includes a first electrode plate and a second electrode plate. The pixel driving circuit can be the pixel driving circuit provided in FIG3.

[0142] In this disclosure, the distance between A and B can refer to the distance between the boundary of A near B and the boundary of B near A, or it can be the distance between the boundary of A away from B and the boundary of B away from A, or it can be the distance between any part of A and any part of B. This disclosure does not limit it in any way.

[0143] In this disclosure, the distance L1 between at least a portion of the orthographic projection of the first adapter FL1 of at least one data adapter on the substrate and at least a portion of the orthographic projection of the active pattern of at least one transistor extending along the first direction D1 on the substrate is less than a first threshold distance, or the distance between the film layer containing the first adapter FL1 of at least one data adapter and the film layer containing the active pattern of at least one transistor is greater than a second threshold distance. Figures 6 and 7 illustrate the case where the distance between at least a portion of the orthographic projection of the first adapter FL1 of at least one data adapter on the substrate and at least a portion of the orthographic projection of the active pattern of at least one transistor extending along the first direction D1 on the substrate is less than the first threshold distance, and Figure 8 illustrates the case where the distance between the film layer containing the first adapter FL1 of at least one data adapter and the film layer containing the active pattern of at least one transistor is greater than the second threshold distance.

[0144] This disclosure reduces or eliminates the load between the data adapter and a portion of the active pattern in the pixel driving circuit by means of a first threshold distance between the orthographic projection of at least a portion of the first adapter of at least one data adapter on the substrate and the orthographic projection of at least a portion of the active pattern of at least one transistor extending along a first direction on the substrate, or a second threshold distance between the film layer where the first adapter of at least one data adapter is located and the film layer where the active pattern of at least one transistor is located.

[0145] In an exemplary embodiment, the second display area A2 is configured to display images, and the position of the first display area A1 may correspond to the position of the optical device. The first display area A1 is configured to display images and transmit light, and the transmitted light is received by the optical device. In an exemplary embodiment, the first display area may be referred to as a light-transmitting display area or an under-display camera (UDC) area, and the second display area may be referred to as a normal display area.

[0146] In an exemplary embodiment, the position of the first display area A1 in the second display area A2 is not limited. It may be located at the upper or lower part of the second display area A2, or at the edge of the second display area A2. This disclosure does not limit it in any way.

The optical device can be an optical sensor such as a fingerprint recognition device, a camera device, or a 3D imaging device. For example, the first display area A1 can be circular, and the size of the orthographic projection of the photosensor onto the display substrate can be less than or equal to the size of the first display area A1. However, this embodiment is not limited to this. In other examples, the first display area can be rectangular, and the size of the orthographic projection of the photosensor onto the display substrate can be less than or equal to the size of the inscribed circle of the first display area.

[0148] In some exemplary embodiments, the display area AA can be rectangular, such as a rounded rectangle. The second display area A2 can be circular or elliptical.

[0149] In an exemplary embodiment, the resolutions of the first display area A1 and the second display area A2 can be the same, or the resolution of the first display area A1 can be lower than the resolution of the second display area A2. For example, the resolution of the first display area A1 can be approximately 50% to 70% of the resolution of the second display area A2. Resolution (Pixels Per Inch, abbreviated as PPI) refers to the number of pixels per unit area, also known as pixel density. The higher the PPI value, the higher the density at which the display substrate can display the image, and the richer the detail of the image.

Typical dimensions (e.g., length) of a Micro LED can be less than 100 μm, for example, 10 μm to 50 μm.

The first direction D1 and the second direction D2 may be located in the same plane. For example, the first direction D1 may be an extension direction parallel to the data signal line Data; the second direction may be an extension direction parallel to the scan signal line or the light emission signal line.

In the at least one pixel driving circuit, the second region 21-2 of the active pattern of the second transistor, the second region 31-2 of the active pattern of the third transistor, and the first region 61-1 of the active pattern of the sixth transistor are integral structures.

In Figures 6 and 7, the pixel driving circuit in the nth row and mth column is the first pixel driving circuit, and the pixel driving circuit in the nth row and (m+1)th column is the second pixel driving circuit.

[0179] In an exemplary embodiment, as shown in Figures 6 and 7, the first adapter cable FL1 of at least one data adapter cable is in the shape of a broken line and includes: a first adapter portion FL11, a second adapter portion FL12 and a third adapter portion FL13.

[0189] The arrangement of the first to third adapters in at least one data adapter in this disclosure can improve the reliability of the display substrate by reducing the coupling capacitance between the signal line connecting at least one data adapter and at least one pixel driving circuit.

[0190] In an exemplary embodiment, as shown in FIG8, when the distance between the film layer where the first adapter FL1 of at least one data adapter line is located and the film layer where the active pattern of at least one transistor is located is greater than a second threshold distance, the first adapter FL1 of at least one data adapter line FL is located on the side of the second adapter FL2 away from the substrate.

[0191] In an exemplary embodiment, as shown in FIG8, the third conductive layer further includes at least: a second adapter FL2 in at least one data adapter FL.

[0195] In an exemplary embodiment, as shown in FIG8, the first adapter cable FL1 of at least one data adapter cable is a straight type.

[0196] In an exemplary embodiment, as shown in FIG8, the orthographic projection of the first adapter line FL1 of at least one data adapter line on the substrate at least partially overlaps with the orthographic projections of the scan signal line Gate and the light emission signal line EM connected to at least one of the pixel driving circuits in the first pixel driving circuit and the second pixel driving circuit on the substrate.

[0197] In an exemplary embodiment, as shown in FIG8, the orthographic projection of the second adapter line FL2 of at least one data adapter line on the substrate at least partially overlaps with the orthographic projection of the active pattern 71 of the seventh transistor in at least one pixel driving circuit on the substrate, and is located between the orthographic projection of the light emission signal line EM connected to the first pixel driving circuit on the substrate and the orthographic projection of the first reset signal line Reset1 connected to the next row of pixel driving circuits of the first pixel driving circuit on the substrate.

[0198] The arrangement of the first and second adapters in at least one data adapter in this disclosure can improve the reliability of the display substrate by reducing the coupling capacitance between the signal line connecting the at least one data adapter and at least one pixel driving circuit.

[0202] In an exemplary embodiment, the orthographic projection of at least one first power line VDD on the substrate covers the orthographic projection of the opening V on the second plate of the capacitor in the pixel driving circuit to which the first power line VDD is connected. This coverage of the opening V on the second plate of the capacitor by the orthographic projection of at least one first power line VDD on the substrate avoids the influence of other signal lines on the first plate of the capacitor, thus ensuring the stability of the signal at the first node in the pixel driving circuit.

[0203] In an exemplary embodiment, at least one light-emitting device located in the first display area A1 is electrically connected to at least one pixel driving circuit located in the second display area A2.

As shown in Figure 9, the light-emitting devices located in at least one of the first display area A1 and the second display area A2 include: a first light-emitting device, a second light-emitting device, and a third light-emitting device.

For instance, the first light-emitting device can be a red light-emitting device, the second light-emitting device can be a green light-emitting device, and the third light-emitting device can be a blue light-emitting device.
