AI Technical Summary
The existing gate driving circuit has a floating stage when providing signals to the gate lines, which causes the gate line voltage to be easily disturbed by coupling of other signal lines, affecting the stability of the output waveform, and thus causing data to be miswrite or write failure, affecting the Display quality.
A shift register is designed, including a first input circuit, a second input circuit, a control circuit, a first output circuit and an output control circuit. By introducing an output control circuit into the shift register, it ensures that the signal output terminal is at any stage. There is a voltage signal to avoid the floating stage.
By eliminating the floating stage, the stability of the shift register output waveform is improved, the anti-interference ability is enhanced, and the risk of data miswrite or write failure is reduced, thereby improving the display quality of the display device.

[0065] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.
[0066] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.
[0067] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.
[0068] When describing some embodiments, the expressions "coupled" and "connected" and their derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. The term "coupled" indicates, for example, that two or more components are in direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that are not in direct contact with each other, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the contents of this document.
[0069] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.
[0070] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.
[0071] As used herein, the term "if" is optionally interpreted to mean "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined that" or "if [stated condition or event] is detected" are optionally interpreted to mean "upon determining" or "in response to determining" or "upon detecting [stated condition or event]" or "in response to detecting [stated condition or event]," depending on the context.
[0072] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.
[0073] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values may, in practice, be based on additional conditions or values beyond those stated.
[0074] As used herein, "about," "approximately," or "substantially" are inclusive of the stated value and mean within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value.
[0075] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.
[0076] It will be understood that when a layer or element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present therebetween.
[0077] Exemplary embodiments are described herein with reference to cross-sectional and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and the area of regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Therefore, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include deviations in shape due to, for example, manufacturing. For example, an etched region shown as a rectangle will typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of regions of the device and are not intended to limit the scope of the exemplary embodiments.
[0078] In this specification, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. It will be further understood that, unless expressly defined herein, terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted as an ideal or overly formal meaning.
[0079] In this disclosure, terms such as "lower," "below," "above," and "upper," and similar terms are used to explain the relationships between components shown in the drawings. These terms may be relative and described based on directions shown in the drawings, or based on the order in which process steps are formed, but are not limited thereto.
[0080] The term "opposite" means that the first element may be directly or indirectly opposite to the second element. In the case where a third element is interposed between the first and second elements, the first and second elements may be understood to be indirectly opposite to each other although they are still opposite to each other.
[0081] In the embodiments of the present disclosure, the transistors used may be thin film transistors (TFT), metal oxide semiconductors (MOS) or other switching devices with the same characteristics. The embodiments of the present disclosure are described using thin film transistors as an example.
[0082] In the embodiments of the present disclosure, the third electrode of each thin film transistor used is the gate of the transistor, the first electrode is one of the source and drain of the thin film transistor, and the second electrode is the other of the source and drain of the thin film transistor. Since the source and drain of the thin film transistor can be symmetrical in structure, the source and drain thereof can be structurally indistinguishable, that is, the first electrode and the second electrode of the thin film transistor in the embodiments of the present disclosure can be structurally indistinguishable. For example, in the case where the transistor is a P-type transistor, the first electrode of the transistor is the source and the second electrode is the drain; for example, in the case where the transistor is an N-type transistor, the first electrode of the transistor is the drain and the second electrode is the source.
[0083] In the embodiments of the present disclosure, the capacitor may be a capacitive device fabricated separately through a process, for example, by fabricating specialized capacitive electrodes, each of which may be implemented through a metal layer, a semiconductor layer (e.g., doped polysilicon), etc. The capacitor may also be a parasitic capacitor between transistors, or implemented through the transistor itself and other devices or circuits, or through the parasitic capacitance between circuits within the circuit itself.
[0084] In the embodiments of the present disclosure, nodes such as the first node and the second node do not represent actual components, but represent the junction points of related electrical connections in the circuit diagram. That is, these nodes are nodes that are equivalent to the junction points of related electrical connections in the circuit diagram.
[0085] In the embodiments of the present disclosure, “operating voltage” refers to a voltage that can turn on the operated transistor included therein; correspondingly, “non-operating voltage” refers to a voltage that cannot turn on the operated transistor included therein.
[0086] In the embodiments of the present disclosure, "low voltage" refers to a voltage that can turn on the operated P-type transistor included therein, but cannot turn on the operated N-type transistor included therein (i.e., the N-type transistor is turned off); correspondingly, "high voltage" refers to a voltage that can turn on the operated N-type transistor included therein, but cannot turn on the operated P-type transistor included therein (i.e., the P-type transistor is turned off).
[0087] In the following, in the circuits provided in the embodiments of the present disclosure, transistors are all described by taking P-type transistors as an example.

[0105] For another example, the substrate 11 may be a flexible substrate, such as a polyethylene terephthalate (PET) substrate, a polyethylene naphthalate (PEN) substrate, or a polyimide (PI) substrate.
[0106] The sub-pixel P includes a pixel circuit 130 and a light-emitting device 140. The sub-pixels P may be arranged in multiple rows and columns, with each row including multiple sub-pixels P arranged along a first direction X, and each column including multiple sub-pixels P arranged along a second direction Y. The first direction X intersects the second direction Y. For example, the first direction X is substantially perpendicular to the second direction Y.
[0107] It should be noted that the first direction X is the row direction in which the plurality of sub-pixels P are arranged, and the second direction Y is the column direction in which the plurality of sub-pixels P are arranged.
[0108] 4 , the array substrate 110 further includes a peripheral region B disposed on at least one side of the display region A. The peripheral region B is a region where no image is displayed and is configured to house a display driving circuit.
[0109] Exemplarily, referring to FIG. 4 , the array substrate 110 further includes a gate driving circuit 10 and a source driving circuit 20 disposed on the substrate 11 and located in the peripheral area B.
[0110] 4 and 6 , the gate driving circuit 10 includes multiple stages of cascaded shift registers RS, and one shift register RS can be electrically connected to at least one row of sub-pixels P. For example, one shift register RS is electrically connected to one row of sub-pixels P.
[0111] It should be noted that some shift registers RS (such as the second shift register RS2 in Figure 6) can also only serve to output cascade signals and are not connected to the sub-pixels P. Please refer to the following for details. No specific examples are given in the embodiments of the present disclosure.
[0112] Here, multi-stage cascade means that, in every two adjacent shift registers RS, the signal input terminal IN of the next stage shift register RS is coupled to the signal output terminal OT of the previous stage shift register RS. The signal input terminal IN of the first stage shift register RS is connected to the initialization signal line SL.
[0113] In some embodiments, referring to FIG. 4 , the array substrate 110 further includes a plurality of gate lines GL and a plurality of data lines DL disposed on the substrate 11 .
[0114] The gate lines GL extend substantially along the first direction X, and one gate line GL can be electrically connected to at least one row of sub-pixels P. The data lines DL extend substantially along the second direction Y, and one data line DL can be electrically connected to at least one column of sub-pixels P.
[0115] At this time, one shift register RS in the gate driving circuit 10 may be electrically connected to a row of sub-pixels P through the gate lines GL, and the source driving circuit 20 may be electrically connected to a column of sub-pixels P through the data lines DL.
[0116] Based on the above, the gate driving circuit 10 can drive the sub-pixels P in each row from one side of the display area A, i.e., single-sided driving. The gate driving circuit 10 can also drive the sub-pixels P in each row from opposite sides of the display area A, i.e., cross driving. The gate driving circuit 10 can also drive the sub-pixels P in each row from opposite sides of the display area A, i.e., double-sided driving.
[0117] The following uses the single-sided driving mode of the gate driving circuit 10 as an example to schematically illustrate some embodiments of the present disclosure. However, the implementation of the present disclosure is not limited to this, and any other driving modes can also be considered as long as the same technical concept is applied.
[0118] In the related art, when a gate driver circuit provides a signal to a gate line, there is a floating phase, in which the gate driver circuit does not provide any signal to the gate. During this floating phase, the voltage of the gate line is easily disturbed by coupling from other signal lines (such as data lines), causing voltage fluctuations (such as voltage drops) on the gate line, thereby affecting the stability of the output waveform of the entire gate driver circuit. This can cause data to be written incorrectly or fail to be written to the sub-pixel, affecting display quality.

This can improve the stability of the output waveform of the shift register RS, improve the anti-interference stability of the shift register RS, reduce the risk of erroneous writing or writing failure of the sub-pixel P data, and thus improve the display quality.
[0167] FIG12 is a simulation comparison diagram of the output voltage of the signal output terminal in the floating stage according to the related art of some embodiments and the output voltage of the signal output terminal in the corresponding stage according to some embodiments of the present application.

In the present application, the voltage drop across the signal output terminal OT of the shift register RS from other signal lines (e.g., the data line DL) is 0.5 V. Compared with the related art, the voltage drop fluctuation is reduced by 0.7 V. Therefore, the present application can significantly improve the stability of the output waveform of the shift register RS, improve the anti-interference stability of the shift register RS, reduce the risk of erroneous data writing or write failure in the sub-pixel P, and thus improve display quality.
