AI Technical Summary
In virtual reality technology, the difference in coupling capacitance between data lines and pixels leads to crosstalk. Especially in the column inversion structure, the voltage of the pixel electrode is prone to deviate from the level, resulting in vertical crosstalk.
By optimizing the design of the array substrate, the spacing between the second conductive part and the adjacent metal line is increased, and the coupling capacitance difference is reduced. Specific measures include adjusting the projection position and shape of the conductive part on the substrate to reduce the difference between the first coupling capacitance and the second coupling capacitance.
It effectively reduces the difference in coupling capacitance, reduces vertical crosstalk, and improves display quality.

Abstract
Description
Array substrate, display panel, and display device Technical Field
[0001] The present invention relates to the field of semiconductor technology, and in particular to an array substrate, a display panel and a display device. Background Art
[0002] Virtual reality technology seamlessly integrates real-world and virtual-world information. Compared to conventional display products, the most notable feature of VR display products is their ultra-high resolution. Liquid crystal display (LCD) technology is currently the best choice for achieving ultra-high PPI. This is because LCD display architectures use only a single switching transistor (TFT) in the pixel area, making it highly suitable for achieving high PPI.

[0071] Those skilled in the art will readily appreciate that the methods and contents may be transformed into one or more forms without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure should not be construed as being limited solely to the contents described in the following embodiments. The embodiments and features of the embodiments in the present disclosure may be combined arbitrarily unless there is a conflict.
[0072] In the drawings, the size of one or more components, layer thicknesses, or regions may be exaggerated for clarity. Therefore, one embodiment of the present disclosure is not necessarily limited to these dimensions, and the shapes and sizes of components in the drawings do not reflect true proportions. Furthermore, the drawings schematically illustrate idealized examples, and one embodiment of the present disclosure is not limited to the shapes or values shown in the drawings.
[0073] In this specification, ordinal numbers such as "first", "second", and "third" are provided to avoid confusion among constituent elements, rather than to limit the quantity. The "plurality" in this disclosure may include two or more.
[0074] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the direction in which the constituent elements are described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced according to the circumstances.
[0075] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted 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 meaning of these terms in this disclosure based on the specific circumstances.
[0076] 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 transmission 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 one or more functions.
[0077] In this specification, a transistor refers to a device that includes at least three terminals: a gate electrode (gate), a drain electrode, and a source electrode. A transistor has a channel region between a drain electrode (drain electrode terminal, drain region, or drain) and a source electrode (source electrode terminal, source region, or source), and current can flow through the drain electrode, the channel region, and the source electrode. In this disclosure, the channel region refers to the region through which current primarily flows.
[0078] The gate of a transistor can also be referred to as the control electrode. The functions of the "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, the terms "source electrode" and "drain electrode" may be interchanged.
[0079] 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 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 includes a state where the angle is greater than 85° and less than 95°.
[0080] In this specification, triangles, rectangles, trapezoids, pentagons or hexagons 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.
[0081] 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."
[0082] In this specification, "approximately" and "substantially" are used without strict limits and allow for process and measurement errors. In this specification, "substantially the same" may refer to values that differ by less than 10%.
[0083] In the related art virtual reality (VR) head-mounted display product, the coupling capacitance Cdp1 between the data line and the electrically connected pixel is 1.322Ff; the coupling capacitance Cdp2 between the data line and the adjacent pixel is 1.173Ff; the difference in coupling capacitance between Cdp1 and Cdp2 (i.e. ) is 11.27%, which is a large difference. In the column inversion structure, the pixel electrode is affected by the large difference in coupling capacitance between the two adjacent data lines (loaded with data signals of opposite polarity), and the voltage of the pixel electrode is easily deviated from the level, which makes crosstalk prone to occur in the vertical direction.
[0084] Specifically, as shown in FIG1A , there is a first coupling capacitor C between the data line and its own pixel electrode (the own pixel electrode can be understood as the pixel electrode electrically connected to the data line) inside the pixel. dp1 , and a second coupling capacitor C with an adjacent pixel electrode (a pixel electrode not electrically connected to the data line) dp2 , when C dp1 >C dp2 When the difference is large, conventional crosstalk problems may occur. For example, when displaying a picture with white in the middle and black at the edges as shown in FIG1B , the picture may appear bright at the top and dark at the bottom, with the middle as the boundary, as shown in FIG1C . Specifically, in conjunction with FIG1B , FIG1C and FIG1D , pixel A1 and pixel A2 are two pixels at different positions on the same data line, pixel B1 and pixel B2 are two pixels at different positions on the same data line, pixel B1 and pixel A1 are two pixels in the same row on adjacent data lines, and pixel B2 and pixel A2 are two pixels in the same row on adjacent data lines; when the pixel self-coupling effect (the first coupling capacitor C dp1 ) and mutual coupling effect (second coupling capacitance C dp2 ) are inconsistent, the charging voltage of pixel A1 is the positive voltage of L127, which will be pulled up by the voltage of L255 in the middle of the screen, causing the voltage difference between pixel A1 and the common electrode voltage (Vcom) to increase, and the display is bright; the charging voltage of pixel A2 is still the negative voltage of the previous frame, which will be pulled up by the voltage of L255 in the middle of the screen, causing the voltage difference between pixel A2 and the common electrode voltage (Vcom) to decrease, and the display is dark, that is, the undesirable phenomenon of bright top and dark bottom of the Crosstalk screen occurs.
[0085] In view of this, referring to Figures 2A-2G and Figure 3, wherein Figure 2B is a schematic diagram of a single film layer of the third metal layer in Figure 2A, Figure 2C is a schematic diagram of a single film layer of the first active layer in Figure 2A, Figure 2D is a schematic diagram of a single film layer of the second metal layer in Figure 2A, Figure 2E is a schematic diagram of a single film layer of the first metal layer in Figure 2A, Figure 2F is a schematic diagram of a single film layer of the first conductive layer in Figure 2A, Figure 2G is a schematic diagram of a single film layer of the second conductive layer in Figure 2A, Figure 3 is a schematic diagram of a cross-section at the dotted line A1A2 in Figure 2A, and Figure 4A is a schematic diagram of only a portion of the film layers in Figure 2A. An embodiment of the present disclosure provides an array substrate, which includes:
[0086] substrate 11;
[0087] The first active layer C1 is located on one side of the substrate 11 and includes a plurality of first active patterns C11. The first active pattern C11 includes a first portion CA and a second portion CB distributed along a first direction X. The second portion CB extends in a different direction from the first portion CA.
[0088] The first metal layer M1 includes: a plurality of first metal lines M11; an orthographic projection of a first portion CA on the substrate 11 is located between orthographic projections of adjacent first metal lines M11 on the substrate 11; a portion of the orthographic projection of a second portion CB on the substrate 11 overlaps with a portion of the orthographic projection of the first metal line M11 on the substrate 11; specifically, the first metal line M11 may be a data line; specifically, the display area AA may have a plurality of first transistors; the second portion CB may serve as a first electrode of the first transistor at a position where it overlaps with the first metal line M11; the second portion CB may be conductive at a position where it overlaps with the first metal line M11, thereby achieving electrical connection between the first transistor and the data line;
[0089] The second metal layer M2 includes: a plurality of second metal lines M21 extending along the second direction Y;
[0090] The first conductive layer D1 includes: a plurality of conductive portions D11 located in the display area AA; the orthographic projection of at least one of the plurality of conductive portions D11 on the substrate 11 is located between the orthographic projections of adjacent first metal lines M11 on the substrate 11; the conductive portion D11 includes: a first conductive portion DA and a second conductive portion DB distributed along the first direction X; the orthographic projection of the first conductive portion DA on the substrate 11 overlaps with the orthographic projection of the first portion CA on the substrate 11, and the second conductive portion DB overlaps with the orthographic projection of the second portion CB on the substrate 11; the first conductive portion DA and the second conductive portion DB extend in different directions; specifically, the first conductive layer D1 may be a transparent conductive layer, and the conductive portion D11 may serve as the second electrode of the first transistor, connecting the first active pattern C11 to the first electrode D21; specifically, the orthographic projection of the conductive portion D11 on the substrate 11 may be a meander, and the maximum length of the conductive portion D11 in the first direction X may be greater than the length in the second direction Y;
[0091] The second conductive layer D2 includes: a plurality of first electrodes D21 located in the display area AA; specifically, the second conductive layer D2 may be a transparent conductive layer, and the material of the second conductive layer D2 may be the same as that of the first conductive layer D1; specifically, the first electrodes D21 may be pixel electrodes; specifically, the orthographic projections of the first electrodes D21 on the substrate 11 may be located between the orthographic projections of adjacent first metal lines M11 on the substrate 11; specifically, the orthographic projections of the first electrodes D21 on the substrate 11 may be in a meandering shape; the length of the first electrodes D21 in the first direction X may be greater than the length in the second direction Y;
[0092] Among them, the first metal wire M11 adjacent to both sides of the conductive part D11 includes: a first sub-metal wire MA, and a second sub-metal wire MB; wherein the first sub-metal wire MA is electrically connected to the second part CB, that is, the first metal wire M11 electrically connected to the second part CB is used as the first sub-metal wire MA, and the other first metal wire M11 is used as the second sub-metal wire MB; the first part CA is electrically connected to the first electrode D21 through the conductive part D11; at least the distance a between the orthographic projection of the second conductive part DB on the substrate 11 and the orthographic projection of the first sub-metal wire MA on the substrate 11 is greater than the distance b between the orthographic projection of the second sub-metal wire MB on the substrate 11.
[0093] In the embodiment of the present disclosure, at least the spacing a between the orthographic projection of the second conductive portion DB on the substrate 11 and the orthographic projection of the first sub-metal line MA on the substrate 11 is greater than the spacing b between the orthographic projection of the second conductive portion DB and the second sub-metal line MB on the substrate 11. This can increase the spacing between the second conductive portion DB and the first sub-metal line MA, thereby reducing the capacitance between the second conductive portion DB and the first sub-metal line MA, and increasing the capacitance between the second sub-metal line MB, thereby reducing the difference between the two, thereby improving poor vertical crosstalk.
[0094] The first metal line M11 and its associated structure can form a first coupling capacitor Cdp1 with its own pixel electrode and its associated structure; the first metal line M11 and its associated structure can form a second coupling capacitor Cdp2 with the adjacent pixel electrode and its associated structure; wherein the own pixel electrode and its associated structure can be the area shown in the dotted box in FIG4A, and specifically can include: the first electrode D21 (as shown in the dotted box S1 in FIG4A), and the conductive portion D11 connected to the first electrode D21 through the second via K2 (as shown in the dotted box S2 in FIG4A), and the conductive portion D11 through the first via K The first active pattern C11 connected to the first active pattern C11 is located at a portion of the second metal line M21 on a side away from the second metal line M21 in the first direction X (as shown by the dotted box S3 in FIG4A , that is, the portion of the first active pattern C11 located below the second metal line M21. Since the time during which each row of pixels is turned on is very short within a display frame, it can be considered that the gate of the first transistor in the pixel is turned off for most of the time, and the portion of the first active pattern C11 covered by the second metal line M21 can be considered as an insulator). The first metal line M11 and the associated structure can be shown as shown by the dotted box in FIG4B . The region may specifically include: the first metal line M11 (as shown in the dotted box S4 in FIG4B ), and a portion of the first active pattern C11 electrically connected to the first metal line M11 through the third via K3 and located on the side of the second metal line M21 close to the second metal line M21 in the first direction X (as shown in the dotted box S5 in FIG4B , that is, the portion of the first active pattern C11 located on the upper side of the second metal line M21); the adjacent pixel electrode and associated structure may be as shown in the dotted box in FIG4C , and specifically include: the adjacent first electrode D21 (as shown in the dotted box S6 in FIG4C ), And the adjacent conductive portion D11 to which the adjacent first electrode D21 is connected through the second via K2 (as shown in the dotted box S7 in Figure 4C ), and the adjacent first active pattern C11 to which the adjacent conductive portion D11 is connected through the first via K1 is located on the side of the second metal line M21 away from the second metal line M21 in the first direction X (as shown in the dotted box S8 in Figure 4C , that is, the portion of the first active pattern C11 located on the lower side of the second metal line M21); the composition of the first coupling capacitor Cdp1 can be as shown in Figure 4D , and the composition of the second coupling capacitor Cdp2 can be as shown in Figure 4E .
[0095] After research by the inventors of this application, it was found that the main reason for the difference between the first coupling capacitor Cdp1 and the second coupling capacitor Cdp2 is the asymmetry of the design of the first active pattern C11. In addition, since the film layer between the first active layer C1 and the first conductive layer D1 is relatively thin, and the first active pattern C11 and the conductive portion D11 in the first coupling capacitor Cdp1 overlap up and down (as shown in the area of the thick solid frame S in FIG4D ), the facing capacitance is relatively large, while there is no such overlap in the second coupling capacitor Cdp2, thereby forming a difference between the first coupling capacitor Cdp1 and the second coupling capacitor Cdp2. (In addition, although the overlapping area between the first active pattern C11 and the first electrode D21 in the first coupling capacitor Cdp1 is larger than the overlapping area between the first active pattern C11 and the conductive portion D11, due to the presence of a thicker film layer between the first active pattern C11 and the first electrode D21, the overlapping capacitance is very small and the difference can be ignored); and since there is only one film layer between the first metal wire M11 and the conductive portion D11, the lateral capacitance formed by the first metal wire M11 and the conductive portion D11 dominates the second coupling capacitor Cdp2.
[0096] In the embodiment of the present disclosure, by making the distance a between the orthographic projection of the second conductive part DB on the substrate 11 and the orthographic projection of the first sub-metal line MA on the substrate 11 greater than the distance b between the orthographic projection of the second conductive part DB on the substrate 11 and the second sub-metal line MB on the substrate 11, the lateral capacitance between the first metal line M11 and the second conductive part DB can be increased, thereby increasing the second coupling capacitance Cdp2. Since the overlapping capacitance between the first active pattern C11 and the conductive part D11 (the area shown by the thick solid box S in Figure 4D) accounts for the majority of the first coupling capacitance Cdp1, the reduced distance between the conductive part D11 and the second sub-metal line MB will not have a significant impact on the first coupling capacitance Cdp1, thereby reducing the difference between the second coupling capacitance Cdp2 and the first coupling capacitance Cdp1, thereby improving poor vertical crosstalk.
[0097] It should be noted that the spacing a between the orthographic projection of the second conductive portion DB on the substrate 11 and the orthographic projection of the first sub-metal wire MA on the substrate 11 may be the minimum spacing a between the orthographic projection of the second conductive portion DB on the substrate 11 and the orthographic projection of the first sub-metal wire MA on the substrate 11; when the outer edge of the orthographic projection of the second conductive portion DB on the substrate 11 is partially uneven due to the manufacturing process, the spacing a between the orthographic projection of the second conductive portion DB on the substrate 11 and the orthographic projection of the first sub-metal wire MA on the substrate 11 may be the average spacing between the orthographic projection of the second conductive portion DB on the substrate 11 and the orthographic projection of the first sub-metal wire MA on the substrate 11; similarly, in the second conductive portion DB When the outer edge of the orthographic projection of the substrate 11 is a straight line, the distance b between the orthographic projection of the second conductive part DB on the substrate 11 and the orthographic projection of the second sub-metal wire MB on the substrate 11 can be the minimum distance b between the orthographic projection of the second conductive part DB on the substrate 11 and the orthographic projection of the second sub-metal wire MB on the substrate 11; when the outer edge of the orthographic projection of the second conductive part DB on the substrate 11 is partially uneven due to the manufacturing process, the distance b between the orthographic projection of the second conductive part DB on the substrate 11 and the orthographic projection of the second sub-metal wire MB on the substrate 11 can be the average distance between the orthographic projection of the second conductive part DB on the substrate 11 and the orthographic projection of the second sub-metal wire MB on the substrate 11.

[0107] In one possible embodiment, in combination with Figures 6A and 6B, the first metal wire M11 includes: a first sub-metal portion M1a and a second sub-metal portion M1b arranged alternately along a first direction X; the first sub-metal portion M1a and the second sub-metal portion M1b have different extension directions; the second sub-edge w12 extends along the extension direction of the first sub-metal portion M1a, specifically, the extension direction of the second sub-edge w12 is the same as the extension direction of the first sub-metal portion M1a.

[0109] In a possible embodiment, as shown in Figure 6C, there is a first bending portion O between the first sub-metal portion M1a and the second sub-metal portion M1a; the first outer edge w1 has a second bending portion Q; the second bending portion Q is located in the area between the orthographic projection of the first metal edge f1 on the substrate 11 and the orthographic projection of the first connecting line OO on the substrate 11, wherein the first metal edge f1 is the outer edge of the second metal wire M21 facing the first conductive portion DA, and the first connecting line OO is the connecting line of the first bending portions O of two adjacent first metal wires M11.

[0111] In one possible embodiment, as shown in conjunction with Figures 6A and 6B , the first outer edge w1 has a second bend Q; the orthographic projection of the second bend Q on the substrate 11 overlaps with the orthographic projection of the first metal edge f1 on the layer substrate 11, wherein the first metal edge f1 is the outer edge of the second metal wire M21 facing the first conductive portion DA. In the disclosed embodiment, the orthographic projection of the second bend Q on the substrate 11 overlaps with the orthographic projection of the first metal edge f1 on the layer substrate 11, thereby achieving a larger spacing between the second conductive portion DB and the first sub-metal wire MA while ensuring the conductive effect of the second via K2 (which connects the conductive portion D11 to the first electrode D21), thereby avoiding the situation where the improper positioning of the second bend Q may affect the conductive effect of the second via K2 connecting the conductive portion D11 to the first electrode D21.

The first conductive portion DA extends in the same direction as the first sub-metal portion M1a. That is, within conductive portion D11, the bending trends of the first conductive portion DA and the second conductive portion DB align with the bending trend of the first metal wire M11, and conductive portion D11 bends accordingly at the location where the first metal wire M11 bends.

[0115] It should be noted that, in Figure 2A, only part of the second electrode portion DD is shown. The second electrode portion DD may have more parts, but the extension direction of the remaining parts of the second electrode portion DD that are not shown may be consistent with the extension direction of the second electrode portion DD shown in the figure. It is only an extension in the extension direction. Specifically, it can be combined with what is shown in Figure 8. The embodiments of the present disclosure are not limited to this.

In other words, the conductive portion D11 can be shifted rightward as a whole to achieve a distance a between the second conductive portion DB and the first sub-metal trace MA that is greater than the distance b between the second conductive portion DB and the second sub-metal trace MB.
[0119] In one possible embodiment, as shown in Figure 6A, the distance c between the orthographic projection of the third outer edge w3 on the substrate 11 and the orthographic projection of the first sub-metal trace MA on the substrate 11 is equal to the distance d between the orthographic projection of the fourth outer edge w4 on the substrate 11 and the orthographic projection of the second sub-metal trace MB on the substrate 11.
[0120] In a possible implementation, as shown in FIG. 2A , the second conductive portion DB has a fifth outer edge w5 extending along the second direction Y. The fifth outer edge w5 is located on a side of the second metal line M21 away from the first conductive portion DA.
[0121] In one possible embodiment, as shown in FIG7 , the second conductive portion DB has a fifth outer edge w5 extending along the second direction Y. The orthographic projection of the second metal line M21 on the substrate covers the orthographic projection of the fifth outer edge w5 on the substrate. In the disclosed embodiment, by retracting the upper end of the second conductive portion DB relative to the second metal line M21, the facing capacitance generated by the vertical overlap of the first active pattern C11 and the conductive portion D11 in the first coupling capacitor Cdp1 (such as the area indicated by the thick solid box S in FIG4D ) can be reduced or eliminated, thereby reducing the first coupling capacitor Cdp1, reducing the coupling capacitance difference between the first coupling capacitor Cdp1 and the second coupling capacitor Cdp2, and reducing the coupling effect of the coupling capacitor on the first metal line M11, thereby avoiding the occurrence of vertical crosstalk.
[0122] In the disclosed embodiment, after the upper end of the second conductive portion DB is retracted into the second metal line M21, the first coupling capacitance Cdp1 between the first metal line M11 and the connected pixel is 1.259Ff; the second coupling capacitance Cdp2 between the first metal line M11 and the adjacent pixel is 1.136Ff; and the coupling capacitance difference between the first coupling capacitance Cdp1 and the second coupling capacitance Cdp2 is 9.77%, which can significantly reduce the coupling effect of the coupling capacitance on the first metal line M11, thereby avoiding the occurrence of vertical crosstalk.
[0123] In a possible embodiment, as shown in FIG. 7 , the second metal wire M21 has a sixth outer edge w6 extending along the second direction Y; the orthographic projection of a portion of the sixth outer edge w6 on the substrate 11 coincides with the orthographic projection of the fifth outer edge w5 on the substrate 11 .

[0125] Both the first active pattern row C100 and the second active pattern row C200 include multiple first active patterns C11. In the first active pattern row C100, the second sub-portion CB2 extends along the third direction Z1. In the second active pattern row C200, the second sub-portion CB2 extends along the fourth direction Z2, with the third direction Z1 intersecting the fourth direction Z2. Specifically, for the two adjacent first sub-metal lines MA and the second sub-metal line MB on either side of the conductive portion D11, the second sub-portion CB2 of the first active pattern row C100 can be located in the first direction X and offset to one side of the first sub-metal line MA, while the second sub-portion CB2 of the second active pattern row C200 can be located in the first direction X and offset to one side of the second sub-metal line MB.
[0126] In the embodiment implemented in FIG8 , by making the first active pattern C11 of adjacent rows a mirror image structure, darker pixel rows and brighter pixel rows can be alternately distributed. If the pixels in the odd-numbered rows are brighter, the pixels in the even-numbered rows are darker. The brightness difference between the upper and lower rows of pixels is neutralized, reducing the coupling effect of the coupling capacitor on the first metal line M11, thereby avoiding the occurrence of vertical crosstalk. Specifically, in the odd-numbered pixel rows, the first coupling capacitor Cdp1 between the first metal line M11 and the connected pixels is 1.192Ff, and in the odd-numbered pixel rows, the first metal line M11 is 0.010Ff. The second coupling capacitance Cdp2 between M11 and the adjacent pixel is 1.301Ff; in the even pixel rows, the first coupling capacitance Cdp1 between the first metal line M11 and the connected pixel is 1.312Ff, and in the even pixel rows, the second coupling capacitance Cdp2 between the first metal line M11 and the adjacent pixel is 1.177Ff; in the odd rows, the pixel second coupling capacitance Cdp2 is greater than the first coupling capacitance Cdp1, and in the even pixel rows, the first coupling capacitance Cdp1 is greater than the second coupling capacitance Cdp2, and the brightness difference between the upper and lower rows of pixels is neutralized.
