[0103] 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

[0104] The scales of the figures in this disclosure can be used as a reference for actual processes, but are not limited to this. For example, the width-to-length 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 panel 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 only structural schematics, and one embodiment of the present disclosure is not limited to the shapes or values ​​shown in the figures.

[0105] 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.

[0106] In this specification, for convenience, terms such as "center," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to describe the positional relationships of components with reference to the accompanying drawings. This is intended solely to facilitate the description of this specification and simplify the description. They do not indicate or imply that the devices or components 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 the components may vary depending on the direction in which the components are described. Therefore, the terms are not limited to those described in this specification and may be appropriately replaced as appropriate.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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°.

[0112] 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."

[0113] 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.

[0114] 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.

[0115] The term "about" in the present disclosure refers to a numerical value that is not strictly defined and allows for process and measurement errors.

[0116] In the display industry, display panels are often manufactured using an oxide process to achieve high uniformity. However, ultra-large display panels are prone to generating transient high static electricity during use due to their large size, which can damage the panel and reduce its reliability.

[0117] Figure 1 is a block diagram of the structure of a display panel, and Figure 2 is a schematic diagram of the structure of a display panel. As shown in Figures 1 and 2, the display panel includes a display area AA and a non-display area AA' located on at least one side of the display area. The display panel may include a timing controller, a data signal driver, and a scan signal driver located in the non-display area, and a pixel array located in the display area. The pixel array may include multiple first scan signal lines G1 and multiple second scan signal lines G2, multiple data signal lines Data, and multiple sub-pixels.

[0118] In an exemplary embodiment, the timing controller may provide grayscale values ​​and control signals suitable for the specifications of the data signal driver to the data signal driver, and may provide clock signals, scan start signals, etc. suitable for the specifications of the scan signal driver to the scan signal driver.

[0119] In an exemplary embodiment, the data signal driver may generate a data voltage to be provided to the data signal line Data using a grayscale value and a control signal received from the timing controller. For example, the data signal driver may sample a grayscale value using a clock signal and apply a data voltage corresponding to the grayscale value to the data signal line Data in units of sub-pixel rows.

[0120] In an exemplary embodiment, the scan signal driver may generate scan signals to be provided to the plurality of first scan signal lines G1 and the plurality of second scan signal lines G2 by receiving a clock signal, a scan start signal, etc. from a timing controller.
