[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present disclosure.
[0044] Unless otherwise defined, technical terms or scientific terms used in the present disclosure should be understood as having the same meaning as commonly understood by those of ordinary skill in the art to which the present disclosure belongs. The terms “first”, “second” and similar terms used in the present disclosure do not indicate any order, number or importance, but are only used to distinguish different components. The terms “include” or “contain” and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, without excluding other elements or objects. The terms “connect” or “connected” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “up”, “down”, “left”, “right” and the like only represent relative positional relationships, which can change accordingly when the absolute positions of the described objects change.
[0045] As used herein, "about" or "approximately" includes the stated value and means within an acceptable range of deviation for the particular value, as determined by one of ordinary skill in the art considering the measurement and error (i.e., limitations) associated with the measurement of the particular quantity. For example, "approximately" can mean within one or more standard deviations, or within ± 30%, 20%, 10%, 5% of the stated value.
[0046] In the drawings, the thicknesses of layers, films, panels, regions, etc., are exaggerated for clarity. The exemplary embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances, are to be expected. Thus, embodiments described herein are not to be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, an area illustrated or described as flat can typically have rough and / or nonlinear features. Moreover, sharp angles that are illustrated can be rounded. Thus, the regions illustrated in the figures are schematic and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.
[0047] In order to make the following description of embodiments of the present disclosure clear and concise, known functions and components are omitted from the detailed description of the present disclosure.
[0048] With the market requirements for screen aperture ratio and transmittance being higher and higher, in the case of ensuring that the aperture ratio of the Dual Gate product is consistent with that of the Single Gate structure, in combination with FIG. 1, the display panel includes: a transparent metal oxide planar electrode 03 (for example, the transparent metal oxide can be indium tin oxide) located in the display area AA, and a vertical common wire 01 located in the same layer as the data line (SD) in the display area AA, and a horizontal common wire 02 located in the non-display area BB, that is, the pixel design of the high-transmittance Dual Gate structure, in the display area AA, the horizontal metal common wire is cancelled, and only the longitudinal metal common wire is reserved. Under this pixel design, the vertical common wire 01 in the display area AA is connected to the planar transparent metal oxide planar electrode 03 through the via hole K. The planar resistance of the transparent metal oxide planar electrode 03 is large, which leads to poor overall conduction and recovery of the common signal. Moreover, in the pixel design of the Dual Gate structure, the vertical common wire 01 of the display area AA also needs to be connected to the horizontal common wire 02 located in the non-display area BB and in different layers through the via hole K when it extends to the top end of the panel. For a mainstream product with high resolution, the vertical common wire 01 of the display area AA has about 2880 roots, which means that 2880 roots need to be additionally punched and connected to the horizontal common wire 02. In addition to the influence of the via hole resistance, the conduction ability of the horizontal common wire 02 is low. Secondly, although the two horizontal common wires 02 are designed in the same layer, an electrostatic short circuit ring (not shown in FIG. 1) is arranged between the two horizontal common wires 02. When the two horizontal common wires 02 are connected, they can only be connected through other film layer structures and via holes, which also affects the overall conduction performance of the common wire. Furthermore, compared with the Single Gate product, the Dual Gate structure panel without the mesh common wire structure has sufficient time to recover when the common voltage is disturbed by the coupling capacitor in the low-frequency case. However, in the high-brush case, the common voltage of the Dual Gate structure panel is difficult to recover in a very short charging time, that is, the common signal cannot be quickly recovered after coupling, resulting in line residual image and crosstalk and other defects.
[0049] Therefore, in combination with FIG. 2, FIG. 3A-FIG. 3C, FIG. 3A can be a specific structure diagram corresponding to each position in FIG. 2, S1 in FIG. 3A can be a structure diagram corresponding to the position S1 in FIG. 2, S2 in FIG. 3A can be a structure diagram corresponding to the position S2 in FIG. 2, S3 in FIG. 3A can be a structure diagram corresponding to the position S3 in FIG. 2, S4 in FIG. 3A can be a structure diagram corresponding to the position S4 in FIG. 2, the dashed box view on the upper right side of the position S2 in FIG. 3A can be an enlarged schematic view of the lower left side of the position S2, FIG. 3B can be a partial film layer schematic view of the position S1 in FIG. 3A, and FIG. 3C can be a partial film layer schematic view of the position S3 in FIG. 3A.
