Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and a method for aligning liquid crystal molecules. Background Technology

[0002] In recent years, the LCD industry has developed rapidly, achieving significant breakthroughs in key technologies such as large size, curved surfaces, and ultra-high resolution. Although new display technologies, such as MicroLEDs, Organic Light Emitting Diodes (OLEDs), and Quantum Dot Light Emitting Diodes (QLEDs), have begun to emerge in the market, their development has been slow due to limitations in both raw materials and equipment precision. Therefore, in the next few years, LCDs will continue to dominate the display industry due to their mature processes, complete material systems, and low cost. Improving transmittance is one of the effective ways for LCDs to achieve "low power consumption."

[0003] Therefore, improving the transmittance of liquid crystal displays is a technical problem that needs to be solved. Summary of the Invention

[0004] The purpose of this application is to provide an alignment method for an array substrate, a display panel, and liquid crystal molecules to improve the light transmittance of the display panel and thus improve the display effect of the display panel.

[0005] In a first aspect, this application provides an array substrate, comprising:

[0006] First substrate;

[0007] Multiple data lines extending along a first direction and spaced apart along a second direction are disposed on the first substrate, wherein the first direction and the second direction intersect.

[0011] Wherein, the orthographic projection of the gap between an adjacent first transparent common electrode line and a second transparent common electrode line along the second direction on the first substrate overlaps with the orthographic projection of at least one pixel electrode on the first substrate.

[0019] In some embodiments, the orthographic projection of at least one of the first transparent common electrode line and the second transparent common electrode line adjacent along the second direction on the first substrate overlaps with the orthographic projection of at least one of the data lines on the first substrate.

[0020] In some embodiments, the array substrate further includes a color resist layer, which is located between the film layer containing the plurality of data lines and the transparent conductive layer.

[0021] In some embodiments, the pixel electrode has an asymmetric structure along the second direction.

[0022] In some embodiments, the pixel electrode includes:

[0023] The first main electrode extends along the first direction;

[0024] The second main electrode extends along the second direction, and one end of the second main electrode is connected between the two ends of the first main electrode.

[0025] Multiple branch electrodes are located on both sides of the second main electrode in the first direction and are respectively connected to the first main electrode and / or the second main electrode;

[0026] Wherein, the orthographic projection of one of the first transparent common electrode lines on the first substrate overlaps with the orthographic projection of the first main electrode and one of the data lines on the first substrate, and the orthographic projection of one of the second transparent common electrode lines on the first substrate overlaps with the orthographic projection of part of the branch electrode and another of the data lines on the first substrate.

[0027] Secondly, this application provides a display panel, the display panel including an array substrate, an opposing substrate and a liquid crystal layer, the opposing substrate being disposed opposite to the array substrate, and the liquid crystal layer being located between the array substrate and the opposing substrate;

[0028] The array substrate includes:

[0029] First substrate;

[0030] Multiple data lines extending along a first direction and spaced apart along a second direction are disposed on the first substrate, wherein the first direction and the second direction intersect.

[0031] A pixel electrode layer is disposed on the first substrate and includes a plurality of pixel electrodes;

[0032] A first transparent common electrode line extending along the first direction is disposed on the first substrate and is insulated from the pixel electrode layer; and

[0033] A second transparent common electrode line extending along the first direction is disposed on the first substrate and is insulated from the pixel electrode layer and disconnected from the first transparent common electrode line;

[0034] Wherein, the orthographic projection of the gap between an adjacent first transparent common electrode line and a second transparent common electrode line along the second direction on the first substrate overlaps with the orthographic projection of at least one pixel electrode on the first substrate.

[0035] Thirdly, this application also provides a liquid crystal molecule alignment method applied to a display panel, the display panel including an array substrate and a counter substrate disposed opposite to each other, a liquid crystal layer disposed between the array substrate and the counter substrate and including a plurality of liquid crystal molecules; the array substrate includes a first substrate and a pixel electrode layer disposed on the first substrate, a first transparent common electrode line extending along a first direction, a second transparent common electrode line extending along the first direction, and a plurality of data lines extending along the first direction and spaced apart along a second direction; the pixel electrode layer includes a plurality of pixel electrodes, the first transparent common electrode line is disconnected from the second transparent common electrode line and is insulated from the pixel electrode layer, the orthographic projection of the gap between an adjacent first transparent common electrode line and a second transparent common electrode line along the second direction on the first substrate overlaps with the orthographic projection of at least one pixel electrode on the first substrate, and the first direction intersects the second direction;

[0036] The method includes:

[0037] A first preset alignment voltage is applied to the first transparent common electrode line;

[0038] A second preset alignment voltage is applied to the second transparent common electrode line, and the second preset alignment voltage is different from the first preset alignment voltage.

[0039] The beneficial effects of some embodiments of this application include: the extending directions of the first transparent common electrode line and the second transparent common electrode line are the same as the extending direction of the data line. The first transparent common electrode line and the second transparent common electrode line are disconnected and insulated from the pixel electrode layer. The orthographic projection of the gap between an adjacent first transparent common electrode line and a second transparent common electrode line along the second direction on the first substrate overlaps with the orthographic projection of at least one pixel electrode on the first substrate. With this configuration, during the liquid crystal alignment stage, alignment voltages can be applied to the first transparent common electrode line and the second transparent common electrode line respectively for adjacent first transparent common electrode lines and second transparent common electrode lines along the second direction. The electric field formed by the voltage difference between the voltage applied to a first transparent common electrode line and the alignment voltage applied to the pixel electrode is independent of the electric field formed by the voltage difference between the voltage applied to a second transparent common electrode line and the voltage applied to the pixel electrode. Therefore, the pretilt angle of the liquid crystal molecules under the electric field formed by the voltage difference between the first transparent common electrode line and the pixel electrode, and the pretilt angle of the liquid crystal molecules under the electric field formed by the voltage difference between the second transparent common electrode line and the pixel electrode, can both be independently controlled, providing conditions for the liquid crystal molecules to tilt towards the area outside the opening region of the pixel electrode in the second direction. This improves the dark pattern problem of the pixel electrode in the second direction, thereby increasing the light transmittance of the display panel and improving the display effect of the display device.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0047] Please refer to Figures 1 to 3 As shown, Figure 1 This is a cross-sectional schematic diagram of a display device according to some embodiments of this application. Figure 2 This is a planar schematic diagram of the transparent conductive layer in some embodiments of this application. Figure 3 This is a planar schematic diagram of the pixel electrode layer, first metal layer, second metal layer, semiconductor layer, and transparent conductive layer in some embodiments of this application.

[0048] like Figure 1 As shown, the display device 300 includes a display panel 100 and a backlight module 200, with the backlight module 200 located on the back side of the light-emitting side of the display panel 100.

[0049] The display panel 100 includes an array substrate 10, an opposing substrate 20, and a liquid crystal layer 30. The array substrate 10 and the opposing substrate 20 are disposed opposite to each other. The liquid crystal layer 30 is disposed between the array substrate 10 and the opposing substrate 20 and includes a plurality of liquid crystal molecules 301.

[0050] The array substrate 10 includes a first substrate 101, a first metal layer 102, a semiconductor layer 103, a second metal layer 104, a transparent conductive layer 105, and a pixel electrode layer 106. The transparent conductive layer 105 is insulated from the pixel electrode layer 106. Figure 2 As shown, the array substrate 10 includes an array region 10a and a peripheral region 10b located around the array region 10a. The array region 10a corresponds to the display region of the display panel 100. The peripheral region 10b corresponds to the non-display region of the display panel 100. The opposing substrate 20 includes a second substrate 201 and a common electrode layer 202. The common electrode layer 202 is disposed on the surface of the second substrate 201 near the array substrate 10.

[0051] The first substrate 101 and the second substrate 201 are disposed opposite to each other. Both the first substrate 101 and the second substrate 201 are glass substrates, but are not limited thereto.

[0052] like Figure 1 and Figure 3 As shown, a first metal layer 102 is disposed on the surface of the first substrate 101 near the second substrate 201. The first metal layer 102 includes a gate 1021 and a scan line 1022. The gate 1021 is connected to the scan line 1022, and the scan line 1022 extends along the second direction y.

[0053] The semiconductor layer 103 is located on the side of the first metal layer 102 away from the first substrate 101. The semiconductor layer 103 includes an active layer 1031, which overlaps with the gate 1021. A first insulating layer 1071 is disposed between the semiconductor layer 103 and the first metal layer 102. It is understood that the semiconductor layer 103 may also be disposed between the first metal layer 102 and the first substrate 101.

[0054] like Figure 1 and Figure 3 As shown, the second metal layer 104 is located on the side of the semiconductor layer 103 away from the first substrate 101. A second insulating layer 1072 is disposed between the second metal layer 104 and the semiconductor layer 103. The second metal layer 104 includes a source 1041 and a drain 1042 connected to the active layer 1031. The second metal layer 104 also includes a plurality of data lines 1043. The plurality of data lines 1043 extend along a first direction x and are spaced apart along a second direction y. The first direction x and the second direction y intersect.

[0055] Specifically, the first direction x is perpendicular to the second direction y, but it is not limited to this. The angle between the first direction x and the second direction y can also be an obtuse angle or an acute angle.

[0056] It should be noted that the source 1041, drain 1042, active layer 1031, and gate 1021 constitute a thin-film transistor T. The source 1041 of the thin-film transistor T is connected to the data line 1043.

[0057] like Figure 1 , Figure 2 as well as Figure 3 As shown, a pixel electrode layer 106 is also disposed on the first substrate 101. The pixel electrode layer 106 includes a plurality of pixel electrodes 1061. The plurality of pixel electrodes 1061 are arranged in an array in the array region 10a along a first direction x and a second direction y. Each pixel electrode 1061 is connected to the drain 1042 of the thin-film transistor T. The material of the pixel electrode layer 106 includes at least one of indium tin oxide and indium zinc oxide.

[0058] like Figure 3 As shown, each pixel electrode 1061 includes a first main electrode 1062 extending along a first direction x, a second main electrode 1063 extending along a second direction y, a plurality of branch electrodes 1064, and a plurality of openings 1065. The first main electrode 1062 is connected to a connection portion 1066. The connection portion 1066 is connected to the drain 1042 of the thin-film transistor T through a via, thereby connecting the first main electrode 1062 to the drain 1042 of the thin-film transistor T.

[0059] One end of the second main electrode 1063 is connected between the two ends of the first main electrode 1062, thereby dividing the pixel electrode 1061 into two domain regions. Multiple branch electrodes 1064 are located on both sides of the second main electrode 1063 in the first direction x, and are respectively connected to the first main electrode 1062 and / or the second main electrode 1063. An opening 1065 is disposed between two adjacent branch electrodes 1064 in one domain region. Therefore, the pixel electrode 1061 is a two-domain pixel electrode.

[0060] It should be noted that, compared to the four-domain pixel electrodes in some related technologies, the two-domain pixel electrodes of this application have fewer backbone electrodes, which is more conducive to improving the aperture ratio of the pixel electrodes. As a result, the display panel 100 has higher light transmittance, thereby improving the display effect of the display device 300. Furthermore, Figure 3 The pixel electrode 1061 shown includes only one first main electrode 1062, which further reduces the number of main electrodes and is more conducive to improving the aperture ratio of the pixel electrode. The display panel 100 has a higher light transmittance, which further improves the display effect of the display device 300.

[0061] When employing a two-domain pixel electrode to improve the aperture ratio, the pixel electrode 1061 in the second direction y has an asymmetric structure. Wherein, Figure 3 The reason why the pixel electrode 1061 shown is asymmetrical in the second direction y includes that the pixel electrode 1061 includes a first main electrode 1062 extending along the first direction x, but does not include an electrode symmetrical to the first main electrode 1062, and the multiple branch electrodes 1064 are also not symmetrical in the second direction y.

[0062] like Figure 1 As shown, a transparent conductive layer 105 is disposed on the first substrate 101. The transparent conductive layer 105 is located on the side of the film layer containing the plurality of data lines 1043 away from the first substrate 101. The transparent conductive layer 105 is located between the film layer containing the plurality of data lines 1043 and the pixel electrode layer 106. This allows at least a portion of the transparent conductive layer 105 to overlap with the data lines 1043. At least a portion of the transparent conductive layer 105 replaces the shielding electrode in the same layer as the pixel electrode 1061 in related technologies. The at least portion of the transparent conductive layer 105 acts as a shielding electrode, which is beneficial for increasing the arrangement area of ​​the pixel electrode 1061 and improving the light transmittance of the display panel 100.

[0063] Specifically, such as Figure 1As shown, the transparent conductive layer 105 is located on the side of the second metal layer 104 away from the first substrate 101. The pixel electrode layer 106 is located on the side of the transparent conductive layer 105 away from the first substrate 101. A third insulating layer 1073 is disposed between the transparent conductive layer 105 and the second metal layer 104. A fourth insulating layer 1074 is disposed between the pixel electrode layer 106 and the transparent conductive layer 105.

[0064] In some embodiments, the first insulating layer 1071, the second insulating layer 1072, and the third insulating layer 1073 are all inorganic insulating layers. The fourth insulating layer 1074 is an organic insulating layer, which serves a planarization function. The material of the inorganic insulating layer is selected from one or more of silicon oxide, silicon nitride, and silicon oxynitride. The material of the organic insulating layer includes one or more of polyimide and polyacrylate.

[0065] In some embodiments, such as Figure 1 As shown, the array substrate 10 also includes a color resist layer 108. The color resist layer 108 is located between the second metal layer 104 where the multiple data lines 1043 are located and the transparent conductive layer 105. The color resist layer 108 includes multiple color resists of different colors, such as red color resist, blue color resist and green color resist.

[0066] Specifically, a third insulating layer 1073 is disposed between the color resist layer 108 and the second metal layer 104. The transparent conductive layer 105 is located on the surface of the color resist layer 108 away from the first substrate 101.

[0067] It should be noted that a color resist layer 108 is disposed between the transparent conductive layer 105 and the second metal layer 104 where the multiple data lines 1043 are located. In this way, the parasitic capacitance between the transparent conductive layer 105 and the multiple data lines 1043 can be reduced, thereby reducing the impact of the parasitic capacitance on the data signal transmitted by the data lines 1043.

[0068] In some embodiments, the transparent conductive layer 105 may also be located between the second metal layer 104, where the multiple data lines 1043 are located, and the first substrate 101. The pixel electrode layer 106 is located on the side of the second metal layer 104 away from the first substrate 101, that is, the transparent conductive layer 105 is located below the second metal layer 104. In some embodiments, the transparent conductive layer 105 may also be located between the first metal layer 102, where the multiple scan lines 1022 are located, and the first substrate 101, that is, the transparent conductive layer 105 is located below the first metal layer 102.

[0069] The transparent conductive layer 105 includes multiple spaced-apart first transparent common electrode lines 1051 and multiple spaced-apart second transparent common electrode lines 1052 arranged along the second direction y. Both the multiple first transparent common electrode lines 1051 and the multiple second transparent common electrode lines 1052 are located in the array region 10a and extend along the first direction x. That is, the extending directions of the first transparent common electrode lines 1051 and the second transparent common electrode lines 1052 are the same as the extending directions of the data lines 1043.

[0070] In the second direction y, a first transparent common electrode line 1051 and a second transparent common electrode line 1052 are disconnected and spaced apart. Therefore, the first transparent common electrode line 1051 and the second transparent common electrode line 1052 are disposed in the same layer to simplify their manufacturing process. Furthermore, both the first transparent common electrode line 1051 and the second transparent common electrode line 1052 are transparent, which helps to improve the light transmittance of the display panel. The material of the transparent conductive layer 105 includes at least one of indium tin oxide and indium zinc oxide.

[0071] In other embodiments, the first transparent common electrode line 1051 and the second transparent common electrode line 1052 may also be located in different transparent conductive layers. This increases the flexibility in manufacturing the first transparent common electrode line 1051 and the second transparent common electrode line 1052.

[0072] It should be noted that the co-layer arrangement of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 means that the first transparent common electrode line 1051 and the second transparent common electrode line 1052 are simultaneously prepared by patterning the same film layer. The fact that the first transparent common electrode line 1051 and the second transparent common electrode line 1052 are located in different transparent conductive layers means that the first transparent common electrode line 1051 and the second transparent common electrode line 1052 are prepared by patterning two different film layers.

[0073] Specifically, multiple first transparent common electrode lines 1051 and multiple second transparent common electrode lines 1052 are alternately arranged one-to-one along the second direction y.

[0074] In some embodiments, when the transparent conductive layer 105 is located between the second metal layer 104 and the pixel electrode layer 106 where multiple data lines 1043 are located, the orthographic projection of at least one of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y onto the first substrate 101 overlaps with the orthographic projection of at least one data line 1043 onto the first substrate 101. Therefore, at least one of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 adjacent along the second direction y can shield the signal transmitted by at least one data line 1043. At least one of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 replaces the shielding electrode in the same layer as the pixel electrode 1061 in related technologies, thereby increasing the arrangement area of ​​the pixel electrode 1061 and further improving the light transmittance of the display panel 100.

[0075] Specifically, such as Figure 3 As shown, the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 overlap with the orthographic projections of two adjacent data lines 1043 on the first substrate 101, respectively. With this configuration, both the first transparent common electrode line 1051 and the second transparent common electrode line 1052 adjacent along the second direction y function as shielding electrodes, further increasing the area of ​​the pixel electrode 1061 and further improving the light transmittance of the display panel 100.

[0076] In other embodiments, the orthographic projection of either one of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 on the first substrate 101 may overlap with the orthographic projection of a data line 1043 on the first substrate 101.

[0077] In some embodiments, the orthographic projection of at least one of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y onto the first substrate 101 overlaps with the orthographic projection of at least one pixel electrode 1061 onto the first substrate 101. With this design, in addition to serving as shielding electrodes, at least one of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 adjacent along the second direction y can also form a storage capacitor with at least one pixel electrode 1061 to store display data.

[0078] In some embodiments, such as Figure 3As shown, the orthographic projection of one of the first transparent common electrode lines 1051 and 1052 adjacent along the second direction y on the first substrate 101 overlaps with the orthographic projection of at least one pixel electrode 1061 on the first substrate 101, while the orthographic projection of the other of the first transparent common electrode lines 1051 and 1052 adjacent along the second direction y on the first substrate 101 does not overlap with the orthographic projection of the pixel electrode 1061 on the first substrate 101.

[0079] In other embodiments, the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 may not overlap with the orthographic projection of the pixel electrode 1061 on the first substrate 101, but may be arranged adjacent to the orthographic projection of at least one pixel electrode 1061 on the first substrate 101.

[0080] In other embodiments, the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 may overlap with the orthographic projection of at least one pixel electrode 1061 on the first substrate 101.

[0081] In some embodiments, the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 overlap at least with the orthographic projection of the main electrode of the pixel electrode 1061 on the first substrate 101.

[0082] For example, for an adjacent first transparent common electrode line 1051 and a second transparent common electrode line 1052, the orthographic projection of the first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projection of the first main electrode 1062 of at least one pixel electrode 1061 on the first substrate 101, and the orthographic projection of the second transparent common electrode line 1052 on the first substrate 101 overlaps with at least the orthographic projection of the second main electrode 1063 of the pixel electrode 1061 on the first substrate 101. This arrangement, while forming a storage capacitor, better controls the liquid crystal molecules above the main electrode from tilting outwards from the opening region, thereby improving the dark line problem around the main electrode.

[0083] In some embodiments, when the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 both overlap with the orthographic projection of at least one pixel electrode 1061 on the first substrate 101, the areas of overlap between the orthographic projections of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 and the orthographic projection of one pixel electrode 1061 on the first substrate 101 are different. Thus, the capacitance values ​​of the storage capacitors formed by the first transparent common electrode line 1051 and the second transparent common electrode line 1052 with the same pixel electrode 1061 are different, to accommodate different capacitance requirements.

[0084] In other embodiments, when the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 both overlap with the orthographic projection of the pixel electrode 1061 on the first substrate 101, the overlapping areas of the orthographic projections of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 on the first substrate 101 and the orthographic projection of the same pixel electrode 1061 on the first substrate 101 can also be the same. Thus, the storage capacitors formed by the first transparent common electrode line 1051 and the second transparent common electrode line 1052 and the same pixel electrode 1061 have the same capacitance value.

[0085] An adjacent second transparent common electrode line 1052 and a first transparent common electrode line 1051 along the second direction y are positioned adjacent to the orthogonal projection of at least one pixel electrode 1061 on the first substrate 101. The gap between an adjacent first transparent common electrode line 1051 and a second transparent common electrode line 1052 along the second direction y is projected onto the first substrate 101 and overlaps with the orthogonal projection of at least one pixel electrode 1061 on the first substrate 101. With this configuration, during the alignment of multiple liquid crystal molecules 301 in the liquid crystal layer 30, an adjacent first transparent common electrode line 1051 and a second transparent common electrode line 1052 along the second direction y form a pair of transparent common electrode lines. The voltage applied to the pair of transparent common electrode lines is matched with the voltage applied to one pixel electrode 1061 to align the multiple liquid crystal molecules 301 controlled by the pixel electrode 1061. Multiple pairs of transparent common electrode lines are subjected to alignment voltage, which is combined with the voltage applied to multiple pixel electrodes 1061 to align multiple liquid crystal molecules 301 controlled by the multiple pixel electrodes 1061.

[0086] Furthermore, during the operation of the display device 300, the same constant voltage is applied to the multiple first transparent common electrode lines 1051 and the multiple second transparent common electrode lines 1052, respectively. Therefore, the multiple first transparent common electrode lines 1051 and the multiple second transparent common electrode lines 1052 have different functions during the alignment process of the liquid crystal molecules 301 and during the display process of the display device 300.

[0087] It should be noted that, when the orthographic projection of the gap between an adjacent second transparent common electrode line 1052 and a first transparent common electrode line 1051 along the second direction y on the first substrate 101 overlaps with the orthographic projection of at least one pixel electrode 1061 on the first substrate 101, at least three designs can be included: (A), (B), and (C). (A) The orthographic projections of an adjacent second transparent common electrode line 1052 and a first transparent common electrode line 1051 along the second direction y on the first substrate 101 can both overlap with the orthographic projection of at least one pixel electrode 1061 on the first substrate 101. (B) The orthographic projection of one of the adjacent second transparent common electrode lines 1052 and 1051 along the second direction y on the first substrate 101 may overlap with the orthographic projection of at least one pixel electrode 1061 on the first substrate 101, and the orthographic projection of the other of the adjacent second transparent common electrode lines 1052 and 1051 along the second direction y on the first substrate 101 may not overlap with the orthographic projection of the pixel electrode 1061 on the first substrate 101. (C) The orthographic projections of the adjacent second transparent common electrode lines 1052 and 1051 along the second direction y on the first substrate 101 may be located on opposite sides of the orthographic projection of at least one pixel electrode 1061 on the first substrate 101, respectively, along the second direction y.

[0088] Figure 3 This diagram merely illustrates the overlap between the orthographic projection of the gap between an adjacent second transparent common electrode line 1052 and a first transparent common electrode line 1051 along the second direction y on the first substrate 101 and the orthographic projection of at least one pixel electrode 1061 on the first substrate 101. For the plurality of pixel electrodes 1061 in the array region 10a, the orthographic projection of an adjacent second transparent common electrode line 1052 and a first transparent common electrode line 1051 along the second direction y on the first substrate 101 overlaps with the orthographic projection of a row of pixel electrodes 1061 arranged side by side along the first direction x on the first substrate 101.

[0089] In some embodiments, such as Figure 3As shown, the orthographic projection of the first transparent common electrode line 1051 on the first substrate 101 is adjacent to the orthographic projection of the first main electrode 1062 on the first substrate 101. The width of the first transparent common electrode line 1051 is greater than the width of the second transparent common electrode line 1052. The widths of both the first and second transparent common electrode lines 1051 and 1052 are greater than the width of the data line 1043. This arrangement allows the first transparent common electrode line 1051 to cover both the adjacent data line 1043 and the first main electrode 1062.

[0090] In some embodiments, the orthographic projection of a first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projections of the first main electrode 1062 of a row of pixel electrodes 1061 arranged side-by-side along the first direction x and a data line 1043 on the first substrate 101. The orthographic projection of a second transparent common electrode line 1052 on the first substrate 101 overlaps with the orthographic projection of another data line 1043 on the first substrate 101. Furthermore, the orthographic projection of the gap between an adjacent second transparent common electrode line 1052 and a first transparent common electrode line 1051 along the second direction y on the first substrate 101 overlaps with the orthographic projections of a plurality of branch electrodes 1064 of a pixel electrode 1061 on the first substrate 101. With this configuration, both the first transparent common electrode line 1051 and the second transparent common electrode line 1052 function as shielding electrodes, and a storage capacitor is formed between the first transparent common electrode line 1051 and the pixel electrode 1061.

[0091] When the pixel electrode 1061 in the second direction y has an asymmetrical structure, if the first transparent common electrode line 1051 and the second transparent common electrode line 1052 of this application are not provided, the light transmittance near the first main electrode 1062 of the pixel electrode 1061 is low, resulting in dark lines appearing near the first main electrode 1062 in the second direction y.

[0092] In this application, the electric field corresponding to the voltage difference between adjacent pixel electrodes 1061 and the first transparent common electrode line 1051 is independently controlled. The electric field corresponding to the voltage difference between adjacent pixel electrodes 1061 and the second transparent common electrode line 1052 is also independently controlled. The pretilt angle of the liquid crystal molecules 301 under the influence of the electric field formed between the first transparent common electrode line 1051 and the pixel electrode 1061, and the pretilt angle of the liquid crystal molecules 301 under the influence of the electric field formed between the second transparent common electrode line 1052 and the pixel electrode 1061, can both be independently controlled. This provides conditions for the liquid crystal molecules 301 to tilt towards the area outside the opening region of the pixel electrode 1061 in the second direction y, which helps to improve the dark pattern problem of the pixel electrode 1061 in the second direction y, thereby increasing the transmittance of the display panel 100 to the backlight emitted by the backlight module 200 and improving the display effect of the display device 300. In particular, when the orthographic projection of a first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projection of the first main electrode 1062 of a row of pixel electrodes 1061 arranged side by side along the first direction x on the first substrate 101, controlling the voltage applied to the first transparent common electrode line 1051 can cause the liquid crystal molecules 301 above the first main electrode 1062 to tilt outward from the opening, thereby improving the problem of low light transmittance near the first main electrode 1062 of the pixel electrode 1061 and the appearance of dark lines in the second direction y.

[0093] It should be noted that in some related technologies, when a full-area transparent conductive layer is used in conjunction with pixel electrode layers and common electrodes to align the liquid crystal, only one voltage can be applied to the full-area transparent conductive layer, which cannot improve the local dark lines that appear when the display panel is displayed. In addition, compared with related technologies where the common electrode line is a metal line, which reduces the transmittance of the display panel, this application uses a first transparent common electrode line 1051 and a second main common electrode line 1054 for the alignment of liquid crystal molecules 301, which can also improve the transmittance of the backlight emitted by the backlight module 200 through the display panel 100.

[0094] Furthermore, in related technologies, the pixel electrode has a larger size in the first direction x, and correspondingly, the dark pattern area of ​​the pixel electrode in the second direction y is larger. This application addresses the issue of the larger dark pattern area of ​​the pixel electrode in the second direction y by adding a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent and spaced apart along the second direction y for each pixel electrode. The orthographic projection of the gap between the adjacent second transparent common electrode line 1052 and the first transparent common electrode line 1051 in the second direction y onto the first substrate 101 overlaps with the orthographic projection of at least one pixel electrode 1061 onto the first substrate 101, which can significantly improve the dark pattern problem of the pixel electrode in the second direction y, thereby significantly improving the light transmittance of the display panel 100.

[0095] As described above, the adjacent second transparent common electrode line 1052 and first transparent common electrode line 1051 in the second direction y can not only serve as shielding electrodes for the data line 1043, but also as electrode plates for the storage capacitor, and can also be used to improve the dark lines near the main electrode extending along the first direction x of the pixel electrode. This configuration eliminates the need for shielding electrodes and electrode plates in related technologies, significantly improving the light transmittance of the display panel.

[0096] It is understood that when the pixel electrode 1061 includes a lateral trunk electrode extending along the second direction y and located at the outermost edge of the pixel electrode 1061, the orthographic projection of the lateral trunk electrode on the first substrate 101 can also overlap with the orthographic projection of the third common electrode line (not shown) on the first substrate 101. This improves the dark freckle problem near the lateral trunk electrode.

[0097] like Figure 2 As shown, the array substrate 10 also includes a first main common electrode line 1053 extending along the second direction y and a second main common electrode line 1054 extending along the second direction y. The first main common electrode line 1053 is located in the peripheral region 10b and is connected to a plurality of first transparent common electrode lines 1051. The second main common electrode line 1054 is located in the peripheral region 10b, is disconnected from the first main common electrode line 1053, and is connected to a plurality of second transparent common electrode lines 1052. The first main common electrode line 1053 and the second main common electrode line 1054 are located on opposite sides of the array region 10a in the first direction x. This facilitates the connection of the first main common electrode line 1053 and the second main common electrode line 1054 to the first transparent common electrode line 1051 and the second transparent common electrode line 1052, respectively, and reduces the risk of short circuit between the first main common electrode line 1053 and the second main common electrode line 1054.

[0098] Specifically, the transparent conductive layer 105 further includes a first main common electrode line 1053 and a second main common electrode line 1054. This configuration simplifies the manufacturing process of the array substrate and the display panel.

[0099] It is understandable that at least a portion of the first main common electrode line 1053 and at least a portion of the second main common electrode line 1054 can also be disposed in the array area 10a. This arrangement is beneficial for the display panel to achieve a narrow bezel structure.

[0100] In this application, during the alignment process of the liquid crystal molecules 301, different alignment voltages can be applied to the first main common electrode line 1053 and the second main common electrode line 1054. During the operation of the display device 300, the same constant voltage is applied to the first main common electrode line 1053 and the second main common electrode line 1054, so that the same constant voltage is applied to multiple first transparent common electrode lines 1051 and multiple second transparent common electrode lines 1052. Please refer to... Figure 4 The diagram shows a planar schematic of the pixel electrode layer, first metal layer, second metal layer, semiconductor layer, and transparent conductive layer in some embodiments of this application. In other embodiments, at least one of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y, has its orthographic projection on the first substrate 101 overlapping with the orthographic projection of the branch electrode 1064 on the first substrate 101. This arrangement increases the overlap area between at least one of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 and the pixel electrode 1061, thereby increasing the capacitance value of the storage capacitor and improving display problems caused by storage capacitor leakage.

[0101] In some embodiments, the area where the orthographic projection of a first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projection of the first main electrode 1062 on the first substrate 101 is greater than the area where the orthographic projection of a second transparent common electrode line 1052 on the first main electrode 1062 overlaps with the orthographic projection of the first main electrode 1062 on the first substrate 101. This arrangement is to adjust the dark lines near the first main electrode 1062 through the first transparent common electrode line 1051.

[0102] In some embodiments, the area of ​​a second transparent common electrode line 1052 is larger than the area of ​​a first transparent common electrode line 1051. This makes it advantageous for the capacitance value of the storage capacitor formed by the second transparent common electrode line 1052 and a pixel electrode to be greater than the capacitance value of the storage capacitor formed by the first transparent common electrode line 1051 and a pixel electrode.

[0103] In some embodiments, the area where the orthographic projection of a first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projection of a plurality of branch electrodes 1064 of a pixel electrode 1061 on the first substrate 101 is smaller than the area where the orthographic projection of a second transparent common electrode line 1052 on the first substrate 101 overlaps with the orthographic projection of a plurality of branch electrodes 1064 of a pixel electrode 1061 on the first substrate 101. This configuration results in a larger capacitance value for the storage capacitor formed between the second transparent common electrode line 1052 and the pixel electrode 1061, thus mitigating display problems caused by leakage of the storage capacitor.

[0104] In one specific embodiment, the orthographic projection of a first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projections of a first main electrode 1062 and a data line 1043 on the first substrate 101, but does not overlap with the orthographic projection of a branch electrode 1064 on the first substrate 101. The orthographic projection of a second transparent common electrode line 1052 on the first substrate 101 overlaps with the orthographic projections of multiple branch electrodes 1064, another data line 1043, and the second main electrode 1063 on the first substrate 101, but does not overlap with the first main electrode 1062. With this configuration, both the first transparent common electrode line 1051 and the second transparent common electrode line 1052 function as shielding electrodes. The first transparent common electrode line 1051 can improve the dark pattern problem around the first main electrode 1062. The storage capacitance formed between the second transparent common electrode line 1052 and the pixel electrode 1061 is larger, which improves the leakage problem of the storage capacitance.

[0105] In other embodiments, the orthographic projection of a first transparent common electrode line 1051 on the first substrate 101 may also overlap with the orthographic projections of a first main electrode 1062, a plurality of branch electrodes 1064 and a data line 1043 on the first substrate 101.

[0106] In other embodiments, the orthographic projection of the gap between a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y onto the first substrate 101 overlaps with the orthographic projection of the branch electrode 1064 onto the first substrate 101. The area of ​​overlap between the first transparent common electrode line 1051 and the second transparent common electrode line 1052 and the pixel electrode 1061 is increased.

[0107] In other embodiments, the minimum spacing d between adjacent first transparent common electrode lines 1051 and 1052 along the second direction y is greater than or equal to 2.5 micrometers and less than or equal to 3.5 micrometers. This configuration increases the area of ​​overlap between the first transparent common electrode lines 1051 and 1052 and the pixel electrode 1061, while also adapting to the process precision required to form the first transparent common electrode lines 1051 and 1052, simplifying the manufacturing difficulty of the display panel 100. If the minimum spacing d between adjacent first transparent common electrode lines 1051 and 1052 along the second direction y is too small, the manufacturing process for the first transparent common electrode lines 1051 and 1052 becomes too difficult. If the minimum spacing d between adjacent first transparent common electrode lines 1051 and 1052 along the second direction y is too large, the utilization rate of the transparent conductive layer 105 is reduced.

[0108] In other embodiments, the orthographic projections of a first transparent common electrode line 1051 and a second transparent common electrode line 1052 adjacent along the second direction y on the first substrate 101 do not overlap with the orthographic projections of the gate 1021 and the active layer 1031 of the thin-film transistor T on the first substrate 101. This reduces the impact of the first transparent common electrode line 1051 and the second transparent common electrode line 1052 on the gate 1021 and the active layer 1031.

[0109] Please refer to Figure 5 As shown, it is a planar schematic diagram of the pixel electrode layer, the first metal layer, the second metal layer, the semiconductor layer and the transparent conductive layer in some other embodiments of this application. Figure 5 The pixel electrode 1061 shown is Figure 3 and Figure 4 The pixel electrode 1061 shown is basically similar, and the similarities will not be repeated. The differences include that the pixel electrode 1061 also includes a third main electrode 1067 extending along the first direction x. The third main electrode 1067 is parallel to and opposite to the first main electrode 1062. The other end of the second main electrode 1063 is connected between the two ends of the third main electrode 1067. A portion of the branch electrode 1064 is connected to the third main electrode 1067. The second transparent common electrode line 1052 overlaps with the third main electrode 1067.

[0110] In some embodiments of this application, when the pixel electrode 1061 simultaneously includes a third main electrode 1067 and a first main electrode 1062, the orthographic projection of the first transparent common electrode line 1051 on the first substrate 101 overlaps with the orthographic projections of the first main electrode 1062 and a data line 1043 on the first substrate 101. Furthermore, the orthographic projection of the second transparent common electrode line 1052 on the first substrate 101 overlaps with the orthographic projections of the third main electrode 1067, another data line 1043, and multiple branch electrodes 1064 on the first substrate 101.

[0111] In other embodiments, the width of the third main electrode 1067 is the same as the width of the first main electrode 1062.

[0112] Voltages are applied to the first transparent common electrode line 1051 and the second transparent common electrode line 1052, respectively. The pretilt angle of the liquid crystal molecules 301 under the electric field formed by the voltage difference between the pixel electrode 1061 and the first transparent common electrode line 1051, and the pretilt angle of the liquid crystal molecules 301 under the electric field formed by the voltage difference between the pixel electrode 1061 and the second transparent common electrode line 1052, can both be independently controlled. The liquid crystal molecules 301 in the liquid crystal layer 30 tilt outwards from the opening region in the second direction y, which helps to improve the dark lines near the third main electrode 1067 and the first main electrode 1062 in the second direction y of the pixel electrode 1061, thereby improving the light transmittance of the display panel 100 and improving the display effect of the display device 300.

[0113] Please refer to Figure 6 The diagram shown is a flowchart illustrating the alignment method of liquid crystal molecules 301 in the display panel of a display device according to some embodiments of this application. The display panel 100 is the display panel of any of the above embodiments of the display device 300, and will not be described again here. The alignment method of the liquid crystal molecules 301 in the display panel 100 includes the following steps:

[0114] Step S101: Apply a first preset alignment voltage to the first transparent common electrode line 1051; and

[0115] Step S102: Apply a second preset alignment voltage to the second transparent common electrode line 1052. The second preset alignment voltage is different from the first preset alignment voltage.

[0116] It should be noted that applying a first preset alignment voltage to the first transparent common electrode line 1051 and applying a second preset alignment voltage to the second transparent common electrode line 1052 can be performed simultaneously, but is not limited to this. Additionally, the above method also includes: not applying voltage to the multiple pixel electrodes 1061, and applying a preset alignment common voltage to the common electrode layer 202.

[0117] During the liquid crystal alignment process, the absolute value of the difference between the voltage (0V) of the pixel electrode 1061 and the first preset alignment voltage is different from the absolute value of the difference between the voltage of the pixel electrode 1061 and the second preset alignment voltage. With this configuration, the electric field strength corresponding to the voltage difference between the first transparent common electrode line 1051 and the pixel electrode 1061 is different from the electric field strength corresponding to the voltage difference between the second transparent common electrode line 1052 and the pixel electrode 1061. Similarly, the pretilt angle of the liquid crystal molecule 301 under the action of the electric field corresponding to the voltage difference between the first transparent common electrode line 1051 and the pixel electrode 1061 is different from the pretilt angle of the liquid crystal molecule 301 under the action of the electric field corresponding to the voltage difference between the second transparent common electrode line 1052 and the pixel electrode 1061.

[0118] For example, during the liquid crystal alignment process, no voltage is applied to the pixel electrode 1061. The alignment common voltage applied to the common electrode layer 202 is 15V. The first preset alignment voltage applied to the first transparent common electrode line 1051 is -8V. The second preset alignment voltage applied to the second transparent common electrode line 1052 is -3V.

[0119] Therefore, the absolute value of the difference between the voltage applied to the pixel electrode 1061 and the first preset alignment voltage applied to the first transparent common electrode line 1051 is 8V. The absolute value of the difference between the voltage applied to the pixel electrode 1061 and the voltage applied to the second transparent common electrode line 1052 is 3V. The strength of the electric field formed between the pixel electrode 1061 and the first transparent common electrode line 1051 is stronger than the strength of the electric field formed between the pixel electrode 1061 and the second transparent common electrode line 1052. The liquid crystal molecules 301 overlapping with the first transparent common electrode line 1051 (e.g., Figure 1 The pretilt angle α of the liquid crystal molecule 301A at the edge of the middle branch electrode is greater than that of the liquid crystal molecule 301 (e.g., the one overlapping with the second transparent common electrode line 1052). Figure 1 The pretilt angle b of the liquid crystal molecules 301B at the edge of the branch electrode. When the first transparent common electrode line 1051 overlaps with the first main electrode 1062, the liquid crystal molecules 301 overlapping with the first transparent common electrode line 1051 are more likely to tilt out of the opening area. That is, the liquid crystal molecules 301 on the first main electrode 1062 are more likely to tilt away from the branch electrode 1064 (connected to the first main electrode 1062), thereby controlling the dark lines near the first main electrode 1062 in the second direction y to be in the non-opening area, improving the transmittance of the display panel 100 to the backlight, and improving the display effect of the display device 300.

[0120] It should be noted that the pretilt angle is based on the thickness direction of the display panel. The greater the angle deviating from the thickness direction, the larger the pretilt angle. For example, the angle of liquid crystal molecule 301A deviating from the reference direction is greater than the angle of liquid crystal molecule 301B deviating from the reference direction. In addition, the display panel 100 also includes two alignment layers (not shown). One alignment layer is located on the array substrate 10 and disposed on the side of the pixel electrode layer 106 away from the first substrate 101. The other alignment layer is located on the opposing substrate 20 and disposed on the side of the common electrode layer 202 away from the second substrate 201. The pretilt angle of the multiple liquid crystal molecules 301 after alignment is fixed by the two alignment layers.

[0121] It should also be noted that the pixel electrode 1061 adopts, as Figure 5 In the case of the pixel electrode shown, the voltage applied to the first transparent common electrode line 1051 and the second transparent common electrode line 1052 can be controlled independently. The liquid crystal molecules 301 adjacent to the first main electrode 1062 and the liquid crystal molecules 301 adjacent to the third main electrode 1067 are all tilted out of the opening area (away from the pixel electrode), thereby controlling the dark lines on both sides of the pixel electrode 1061 in the second direction y to be in the non-opening area, improving the transmittance of the display panel 100 to the backlight, and improving the display effect of the display device 300.

[0122] In other embodiments, the second preset alignment voltage may be the same as the first preset alignment voltage.

[0123] The above description of the embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application; those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
