[0164] Details

[0165] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Note that the embodiments can be implemented in a variety of different forms. A person of ordinary skill in the art can easily understand the fact that the methods and contents can be transformed into various 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. Unless there is a conflict, the embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined with each other. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of some known functions and known components. The drawings of the embodiments of the present disclosure only involve structures related to the embodiments of the present disclosure. Other structures can refer to the general design

[0166] The scales of the figures in this disclosure can be used as a reference for actual processes, but are not limited to such. For example, the width-to-length ratio of the channel, the thickness and spacing of the various film layers, and the width and spacing of the various signal lines 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 numbers shown in the figures. The figures described in this disclosure are merely schematic structural diagrams, and one embodiment of this disclosure is not limited to the shapes or values ​​shown in the figures.

[0167] 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.

[0168] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the direction in which each constituent element is described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced according to the circumstances.

[0169] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, indirect connections through intermediaries, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure.

[0170] In this specification, a transistor refers to a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between a drain electrode (drain electrode terminal, drain region, or drain electrode) and a source electrode (source electrode terminal, source region, or source electrode), and current can flow through the drain electrode, the channel region, and the source electrode. Note that in this specification, the channel region refers to the region through which current primarily flows.

[0171] In this specification, the first electrode can be a drain electrode and the second electrode can be a source electrode, or vice versa. The functions of "source electrode" and "drain electrode" may be interchanged when using transistors with opposite polarity or when the direction of current changes during circuit operation. Therefore, in this specification, "source electrode" and "drain electrode" may be interchanged.

[0172] 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 the transfer of electrical signals between the connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other components with various functions.

[0173] 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°.

[0174] In this specification, the terms "film" and "layer" may be interchanged. For example, "conductive layer" may be replaced with "conductive film." Similarly, "insulating film" may be replaced with "insulating layer."

[0175] In this specification, the term "same-layer arrangement" refers to a structure formed by patterning two (or more) structures using the same patterning process. The materials of these structures can be the same or different. For example, the precursor materials for forming the multiple structures arranged in the same layer can be the same, and the materials of the final structures can be the same or different.

[0176] The triangles, rectangles, trapezoids, pentagons or hexagons in this specification are not in the strict sense, but may be approximate triangles, rectangles, trapezoids, pentagons or hexagons, etc. There may be some small deformations caused by tolerances, and there may be chamfers, arc edges and deformations.

[0177] The term "about" in the present disclosure refers to a numerical value that is not strictly defined and allows for process and measurement errors.

[0178] The "integrated structure" in the embodiments of the present disclosure may refer to a structure in which two (or more) structures are formed by the same deposition process and patterned by the same composition process to be connected to each other, and their materials may be the same or different.

[0179] With the development of society and the enrichment of material conditions, while display devices provide people with many conveniences, privacy leaks are always inevitable and cannot meet the needs of users.

[0180] Figure 1A is a schematic diagram of the structure of a display device. As shown in Figure 1A, the display device may include a timing controller, a data signal driver, a scan signal driver, a light emitting signal driver, and a pixel array. The timing controller is respectively connected to the data signal driver, the scan signal driver, and the light emitting signal driver. The data signal driver is respectively connected to a plurality of data signal lines (D1 to Dn), the scan signal driver is respectively connected to a plurality of scan signal lines (S1 to Sm), and the light emitting signal driver is respectively connected to a plurality of light emitting signal lines (E1 to Eo). The pixel array may include a plurality of sub-pixels Pxij, where i and j may be natural numbers. At least one sub-pixel Pxij may include a circuit unit and a light emitting device connected to the circuit unit. The circuit unit may include a pixel driving circuit, and the pixel driving circuit may be respectively connected to the scan signal lines, the light emitting signal lines, and the data signal lines.

[0181] In an exemplary embodiment, the timing controller may provide the data signal driver with grayscale values ​​and control signals that meet the specifications of the data signal driver; may provide the scan signal driver with clock signals, scan start signals, and other signals that meet the specifications of the scan signal driver; and may provide the light signal driver with clock signals, emission stop signals, and other signals that meet the specifications of the light signal driver. The data signal driver may use the grayscale values ​​and control signals received from the timing controller to generate data voltages to be supplied to the data signal lines D1, D2, D3, ..., and Dn. For example, the data signal driver may sample grayscale values ​​using the clock signal and apply data voltages corresponding to the grayscale values ​​to the data signal lines D1 to Dn on a pixel row basis, where n may be a natural number. The scan signal driver may generate scan signals to be supplied to the scan signal lines S1, S2, S3, ..., and Sm by receiving the clock signal, scan start signals, and other signals from the timing controller. For example, the scan signal driver may sequentially supply scan signals having on-level pulses to the scan signal lines S1 to Sm. For example, the scan signal driver can be constructed in the form of a shift register and can generate a scan signal by sequentially transmitting a scan start signal provided in the form of an on-level pulse to the next level circuit under the control of a clock signal, and m can be a natural number. The light-emitting signal driver can generate an emission signal to be provided to the light-emitting signal lines E1, E2, E3, ... and Eo by receiving a clock signal, an emission stop signal, etc. from a timing controller. For example, the light-emitting signal driver can sequentially provide an emission signal with an off-level pulse to the light-emitting signal lines E1 to Eo. For example, the light-emitting signal driver can be constructed in the form of a shift register and can generate an emission signal by sequentially transmitting an emission stop signal provided in the form of an off-level pulse to the next level circuit under the control of a clock signal, and o can be a natural number.

[0182] In an exemplary embodiment, the light emitting device may be an organic electroluminescent diode (OLED) including a first electrode (anode), an organic light emitting layer, and a second electrode (cathode) stacked.

[0183] In an exemplary embodiment, the organic light-emitting layer may include an emissive layer (EML) and any one or more of the following layers: a hole injection layer (HIL), a hole transport layer (HTL), an electron blocking layer (EBL), a hole blocking layer (HBL), an electron transport layer (ETL), and an electron injection layer (EIL). In an exemplary embodiment, one or more of the hole injection layer, hole transport layer, electron blocking layer, hole blocking layer, electron transport layer, and electron injection layer of all sub-pixels may be a common layer connected together, and the emissive layers of adjacent sub-pixels may have a small overlap or may be isolated.

[0184] FIG1B is a schematic diagram of an equivalent circuit of a pixel driving circuit. In an exemplary embodiment, the pixel driving circuit can be a 3T1C, 4T1C, 5T1C, 5T2C, 6T1C, 7T1C, or 8T1C structure. As shown in FIG1B , the pixel driving circuit can include 7 transistors (a first transistor T1 to a seventh transistor T7), a capacitor C, and the pixel driving circuit can be connected to 7 signal segments (a data signal terminal Data, a scan signal terminal Gate, a reset signal terminal Reset, an emission signal terminal EM, a first initial signal terminal INIT1, an anode initial signal terminal INIT2, a first power supply terminal VDD, and a second power supply terminal VSS).

[0185] In an exemplary embodiment, the pixel driving circuit may include a first node N1, a second node N2, and a third node N3. The first node N1 is connected to the first electrode of the third transistor T3, the second electrode of the fourth transistor T4, and the second electrode of the fifth transistor T5, respectively. The second node N2 is connected to the second electrode of the first transistor, the first electrode of the second transistor T2, the gate electrode of the third transistor T3, and the second end of the capacitor C, respectively. The third node N3 is connected to the second electrode of the second transistor T2, the second electrode of the third transistor T3, and the first electrode of the sixth transistor T6, respectively.

[0186] In an exemplary embodiment, a first terminal of the capacitor C is connected to the first power supply terminal VDD, and a second terminal of the capacitor C is connected to the second node N2 , ie, the second terminal of the capacitor C is connected to the gate electrode of the third transistor T3 .

[0187] The gate electrode of the first transistor T1 is connected to the reset signal terminal Reset, the first electrode of the first transistor T1 is connected to the first initial signal terminal INIT1, and the second electrode of the first transistor is connected to the second node N2. The first transistor T1 can be called a node reset transistor. When the on-level scanning signal is applied to the reset signal terminal Reset, the first transistor T1 transmits an initialization voltage to the gate electrode of the third transistor T3 to initialize the charge amount of the gate electrode of the third transistor T3.

[0188] The gate electrode of the second transistor T2 is connected to the scan signal terminal Gate, the first electrode of the second transistor T2 is connected to the second node N2, and the second electrode of the second transistor T2 is connected to the third node N3. The second transistor can be called a compensation transistor. When the on-level scan signal is applied to the scan signal terminal Gate, the second transistor T2 connects the gate electrode of the third transistor T3 to the second electrode.

[0189] The gate electrode of the third transistor T3 is connected to the second node N2, that is, the gate electrode of the third transistor T3 is connected to the second end of the capacitor C. The first electrode of the third transistor T3 is connected to the first node N1, and the second electrode of the third transistor T3 is connected to the third node N3. The third transistor T3 can be called a driving transistor. The third transistor T3 determines the magnitude of the driving current flowing between the first power supply terminal VDD and the second power supply terminal VSS based on the potential difference between the gate electrode and the first electrode of the third transistor T3.

[0190] A gate electrode of the fourth transistor T4 is connected to the scan signal terminal Gate, a first electrode of the fourth transistor T4 is connected to the data signal terminal Data, and a second electrode of the fourth transistor T4 is connected to the first node N1. The fourth transistor T4 can be called a write transistor, etc. When a conduction-level scan signal is applied to the scan signal terminal Gate, the fourth transistor T4 inputs a data voltage at the data signal terminal Data to the pixel driving circuit.

[0191] The gate electrode of the fifth transistor T5 is connected to the light-emitting signal terminal EM, the first electrode of the fifth transistor T5 is connected to the first power supply terminal VDD, and the second electrode of the fifth transistor T5 is connected to the first node N1. The gate electrode of the sixth transistor T6 is connected to the light-emitting signal terminal EM, the first electrode of the sixth transistor T6 is connected to the third node N3, and the second electrode of the sixth transistor T6 is connected to the first electrode of the light-emitting device. The fifth transistor T5 can be referred to as a first light-emitting transistor, and the sixth transistor T6 can be referred to as a second light-emitting transistor. When an on-level light-emitting signal is applied to the light-emitting signal terminal EM, the fifth transistor T5 and the sixth transistor T6 form a drive current path between the first power supply terminal VDD and the second power supply terminal VSS, thereby causing the light-emitting device to emit light.

[0192] The gate electrode of the seventh transistor T7 is connected to the reset signal terminal Reset, the first electrode of the seventh transistor T7 is connected to the second initialization signal terminal INIT2, and the second electrode of the seventh transistor T7 is connected to the first electrode of the light-emitting device. The seventh transistor T71 can be referred to as an anode reset transistor. When the on-level scan signal is applied to the reset signal terminal Reset, the seventh transistor T7 transmits an initialization voltage to the first electrode of the light-emitting device to initialize or release the charge accumulated in the first electrode of the light-emitting device.

[0193] In an exemplary embodiment, the second electrode of the light-emitting device is connected to the second power supply terminal VSS. The signal at the second power supply terminal VSS is a low-level signal, while the signal at the first power supply terminal VDD is a continuously high-level signal. The scan signal terminal Gate is the scan signal terminal in the pixel driving circuit of the current display row, and the reset signal terminal Reset is the scan signal terminal in the pixel driving circuit of the previous display row. The reset signal terminal Reset of the current display row is the same signal terminal as the scan signal terminal Gate in the pixel driving circuit of the previous display row. This can reduce the number of signal terminals on the display substrate and achieve a narrow bezel on the display substrate.

[0194] Transistors can be divided into N-type transistors and P-type transistors according to their characteristics. When the transistor is a P-type transistor, the turn-on voltage is a low-level voltage (e.g., 0V, -5V, -10V, or other suitable voltages), and the turn-off voltage is a high-level voltage (e.g., 5V, 10V, or other suitable voltages). When the transistor is an N-type transistor, the turn-on voltage is a high-level voltage (e.g., 5V, 10V, or other suitable voltages), and the turn-off voltage is a low-level voltage (e.g., 0V, -5V, -10V, or other suitable voltages).

[0195] In an exemplary embodiment, the first transistor T1 to the seventh transistor T7 may be a P-type transistor or an N-type transistor. Using the same type of transistors in the pixel driving circuit can simplify the process flow, reduce the manufacturing difficulty of the display panel, and improve the product yield. In some possible implementations, the first transistor T1 to the seventh transistor T7 may include P-type transistors and N-type transistors.

[0196] Figure 1C is an operating timing diagram of a pixel driving circuit. The following illustrates exemplary embodiments of the present disclosure using the operating process of the pixel driving circuit illustrated in Figure 1B . The pixel driving circuit in Figure 1B includes seven transistors (first transistor T1 to seventh transistor T7) and one capacitor C. All seven transistors are P-type transistors.

[0197] In an exemplary embodiment, the operation process of the pixel driving circuit may include:

[0198] The first phase S1 is called the reset phase. The signal at the reset signal terminal Reset is a low-level signal, while the signals at the scanning signal terminal Gate and the emission signal terminal EM are high-level signals. The low-level signal at the reset signal terminal Reset turns on the first transistor T1. The signal at the first initial signal terminal INIT1 is supplied to the second node N2, initializing (resetting) the capacitor C and clearing the existing charge in the capacitor. The seventh transistor T7 turns on, and the initial voltage at the second initial signal terminal INIT2 is supplied to the first electrode of the light-emitting device L, initializing (resetting) the first electrode of the light-emitting device L and clearing the pre-stored voltage therein, completing the initialization. The high-level signals at the scanning signal terminal Gate and the emission signal terminal EM turn on the second transistor T2, the fourth transistor T4, the fifth transistor T5, and the sixth transistor T6. During this phase, the light-emitting device L does not emit light.

[0199] In the second phase S2, also known as the data writing phase or threshold compensation phase, the signal at the scan signal terminal Gate is a low-level signal, the signals at the reset signal terminal Reset and the luminescence signal terminal EM are high-level signals, and the data signal terminal Data outputs a data voltage. During this phase, since the second terminal of capacitor C is at a low level, the third transistor T3 is turned on. The low-level signal at the scan signal terminal Gate turns on the second transistor T2 and the fourth transistor T4. The second transistor T2 and the fourth transistor T4 are turned on, causing the data voltage output by the data signal terminal Data to be provided to the second node N2 via the first node N1, the turned-on third transistor T3, the third node N3, and the turned-on second transistor T2. The difference between the data voltage output by the data signal terminal Data and the threshold voltage of the third transistor T3 is charged into capacitor C. The voltage at the second terminal of capacitor C (second node N2) is Vd-|Vth|, where Vd is the data voltage output by the data signal terminal Data and Vth is the threshold voltage of the third transistor T3. The signals of the reset signal terminal Reset and the emission signal terminal EM are high-level signals, so that the first transistor T1 , the fifth transistor T5 , the sixth transistor T6 and the seventh transistor T7 are turned off.

[0200] In the third phase S3, referred to as the light-emitting phase, the signal at the light-emitting signal terminal EM is a low-level signal, while the signals at the scan signal terminal Gate and the reset signal terminal Reset are high-level signals. The low-level signal at the light-emitting signal terminal EM turns on the fifth transistor T5 and the sixth transistor T6. The power supply voltage output by the first power supply terminal VDD provides a driving voltage to the first electrode of the light-emitting device L through the turned-on fifth transistor T5, the third transistor T3, and the sixth transistor T6, thereby driving the light-emitting device L to emit light.

[0201] During the driving process of the pixel driving circuit, the driving current flowing through the third transistor T3 (driving transistor) is determined by the voltage difference between its gate electrode and the first electrode. Since the voltage of the second node N2 is Vdata-|Vth|, the driving current of the third transistor T3 is: I=K*(Vgs-Vth) 2 =K*[(Vdd-Vd+|Vth|)-Vth] 2 =K*(Vdd-Vd) 2

[0202] Wherein, I is the driving current flowing through the third transistor T3, that is, the driving current driving the light-emitting device L, K is a constant, Vgs is the voltage difference between the gate electrode and the first electrode of the third transistor T3, Vth is the threshold voltage of the third transistor T3, Vd is the data voltage output by the data signal terminal Data, and Vdd is the power supply voltage output by the first power supply terminal VDD.

[0203] It can be seen from the derivation results of the above current formula that in the light-emitting stage, the driving current of the third transistor T3 is no longer affected by the threshold voltage of the third transistor T3, thereby eliminating the influence of the threshold voltage of the third transistor T3 on the driving current, ensuring uniform display brightness of the display product and improving the display effect of the entire display product.

[0285] The following is an illustrative explanation using the preparation process of a display substrate. The "patterning process" mentioned in the present disclosure includes processes such as coating photoresist, mask exposure, development, etching, and stripping photoresist for metal materials, inorganic materials, or transparent conductive materials, and includes processes such as coating organic materials, mask exposure, and development for organic materials. Deposition can be performed by any one or more of sputtering, evaporation, and chemical vapor deposition; coating can be performed by any one or more of spraying, spin coating, and inkjet printing; and etching can be performed by any one or more of dry etching and wet etching, which are not limited in the present disclosure. "Thin film" refers to a thin film made 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 called a "layer." If the "thin film" requires a patterning process during the entire production process, it is called 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." As used in this disclosure, "A and B are disposed in the same layer" means that A and B are formed simultaneously through the same patterning process, and the "thickness" of the film layer refers to the dimension of the film layer in a direction perpendicular to the display substrate. In exemplary embodiments of this disclosure, "the orthographic projection of B is within the range of the orthographic projection of A" or "the orthographic projection of A contains 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 that the boundary of the orthographic projection of A overlaps with the boundary of the orthographic projection of B.
