[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to the international application filed with the State Intellectual Property Office of the People's Republic of China on August 29, 2023, with application number PCT / CN2023 / 115605 and application name "Array Substrate, Display Panel and Display Device", the entire contents of which are incorporated by reference into this application. Technical Field
[0003] The present disclosure relates to the field of semiconductor technology, and in particular to an array substrate, a display panel, and a display device. Background Art
[0004] The name UV2A comes from the multiplication of ultraviolet (UV) light and the VA method of the liquid crystal panel. This technology can precisely manipulate the alignment of liquid crystal molecules through ultraviolet light, greatly improving the light transmittance.
[0005] The key to UV2A lies in its use of a special polymer material as an alignment film, precisely controlling the tilt of liquid crystal molecules along the direction of ultraviolet light. This accuracy is measured in picometers (one trillionth of a meter). UV2A's advantage lies in its simple LCD panel structure, free of protrusions and slits. This "dream of LCD technicians" was explored as early as 30 years ago. Today, thanks to the availability of new materials, production equipment, and a refined processing process, this dream has become a reality. This simple LCD panel structure not only improves production efficiency but also offers numerous advantages in image quality.

[0229] 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 clearly and completely described 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, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. The implementation methods can be implemented in multiple different forms. Ordinary technicians in the relevant technical field can easily understand the fact that the method and content can be transformed into one or more forms without departing from the purpose and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited to the contents described in the following implementation methods. In the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other in any way.
[0230] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
[0231] As used herein, "about" or "approximately the same" is inclusive of 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, taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "approximately the same" may mean that the difference relative to the stated value is within one or more standard deviations, or within ±30%, 20%, 10%, 5%. In this specification, "approximately the same" may refer to values that are within 10% of each other.
[0232] In the accompanying drawings, the thickness of layers, films, panels, regions, etc. are exaggerated for clarity. Exemplary embodiments are described herein with reference to cross-sectional views that are schematic representations of idealized embodiments. As such, deviations from the shapes of the figures are to be expected as a result of, for example, manufacturing techniques and / or tolerances. Thus, the embodiments described herein should not be construed as limited to the specific shapes of the regions as shown herein, but rather include deviations in shape that result from, for example, manufacturing. For example, a region illustrated or described as flat may typically have rough and / or nonlinear features. Furthermore, sharp corners illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.
[0233] 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.
[0234] 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.
[0235] 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.
[0236] 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.
[0237] 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.
[0238] 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°.
[0239] 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.
[0240] 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."
[0241] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components.
[0242] High-resolution products, such as 8K and 16K display products, are the main direction of subsequent products. However, the current 8K products using vertical alignment liquid crystal (VA) have problems with low transmittance and poor color deviation.
[0243] In view of this, referring to Figures 1A-1G, 2A-2G, 3A-3G, 4A-4G, 5A-5G, 6A-6G, 11A-11I, 13A-13C, 14A-14C, 15A-15C, 16A-16I, 17A-17C, 18A-18C, 19A-19C, 20A-20K, 21A-21C, 22A-22C, and 23A-23C, an embodiment of the present disclosure provides an array substrate, comprising:
[0244] Substrate 1;
[0245] A plurality of gate lines 2 are located on one side of the substrate 1 and extend along a first direction X;
[0246] The plurality of data lines 3 extend along a second direction Y; specifically, the second direction Y may intersect the first direction X; specifically, the second direction Y may be perpendicular to the first direction X; specifically, the second direction Y may be a direction of pixel electrode columns, and the first direction X may be a direction of pixel electrode rows;
[0247] A plurality of pixel electrodes 4, the pixel electrodes 4 including: a first pixel electrode 41 located on one side of the gate line 2, and a second pixel electrode 42 located on the other side of the gate line 2; the first pixel electrode 41 including: a first sub-pixel electrode 411 and a second sub-pixel electrode 412 distributed along the first direction X; the second pixel electrode 42 including: a third sub-pixel electrode 421 and a fourth sub-pixel electrode 422 distributed along the first direction X; specifically, for example, with reference to FIG1G , the pixel electrode 4 includes the first pixel electrode 41 located on the upper side of the gate line 2, and the second pixel electrode 42 located on the lower side of the gate line 2, wherein the first pixel electrode 41 includes the first sub-pixel electrode 411 located on the left side, and the second sub-pixel electrode 412 located on the right side; the second pixel electrode 42 includes the third sub-pixel electrode 421 located on the left side, and the fourth sub-pixel electrode 422 located on the right side;
[0248] One of the first subpixel electrode 411 and the second subpixel electrode 412 is electrically connected to one of the third subpixel electrode 421 and the fourth subpixel electrode 422. The brightness of the two electrically connected electrodes is different from the brightness of the other two electrodes. Specifically, for example, the first subpixel electrode 411 may be electrically connected to the third subpixel electrode 421, and the second subpixel electrode 412 may be electrically connected to the fourth subpixel electrode 422; or the first subpixel electrode 411 may be electrically connected to the fourth subpixel electrode 422, and the second subpixel electrode 412 may be electrically connected to the third subpixel electrode 422.
[0249] In the embodiment of the present disclosure, the pixel electrode 4 includes: a first pixel electrode 41 located on one side of the gate line 2, and a second pixel electrode 42 located on the other side of the gate line 2; the first pixel electrode 41 includes: a first sub-pixel electrode 411 and a second sub-pixel electrode 412 distributed along the first direction X; the second pixel electrode 42 includes: a third sub-pixel electrode 421 and a fourth sub-pixel electrode 422 distributed along the first direction X; and one of the first sub-pixel electrode 411 and the second sub-pixel electrode 412 is electrically connected to one of the third sub-pixel electrode 421 and the fourth sub-pixel electrode 422. That is, a pixel electrode 4 is divided into upper and lower parts, the upper half is further divided into left and right parts, and the lower half is also divided into left and right parts. The brightness of the two electrically connected parts is different from the brightness of the other two parts, and an 8-domain distribution can be formed in a sub-pixel. Compared with a conventional 8-domain structure, the array substrate provided by the embodiment of the present disclosure has fewer dark lines, better transmittance, and can compensate for the viewing angles, thereby improving the color deviation of the left and right viewing angles.
[0250] Specifically, as shown in Figures 7 and 8, Figure 7 shows the dark lines of the conventional 8-domain structure. It can be seen that there are more dark lines, which have a great impact on the transmittance. Figure 8 shows the dark lines of the array substrate provided by the embodiment of the present disclosure. It can be clearly seen that the number of dark lines is significantly reduced. In comparison, the 8-domain array substrate structure provided by the disclosed embodiment has obvious advantages in improving the transmittance. Moreover, the 8-domain structure shown in Figure 7 does not have a good liquid crystal angle that can compensate for the left and right viewing angles. The horizontal liquid crystals are all facing right, and there is no horizontal liquid crystal facing left. However, the array substrate provided by the embodiment of the present disclosure shown in Figure 8 can make the horizontal liquid crystals in the left and right directions compensate for each other's viewing angles, thereby improving the color deviation of the left and right viewing angles.
[0251] As shown in Figures 1A, 1G and 8, in a pixel electrode 4, the first pixel electrode 41 is a U-shaped slit, and the second pixel electrode 42 is an inverted U-shaped Slit; in conjunction with the extension direction of the slit F, the first pixel electrode 41 can be set with two liquid crystal alignment directions, which can be 225° and 135° respectively; the second pixel electrode 42 can be set with two liquid crystal alignment directions, which can be 315° and 45° respectively; and combined with the left and right divided light and dark areas, an alignment mode of 8 domains in a sub-pixel can be formed when using SUVA technology.
[0252] It should be noted that in the disclosed embodiment, the electrical connection between the first sub-pixel electrode 411 and the second sub-pixel electrode 412 and the third sub-pixel electrode 421 and the fourth sub-pixel electrode 422 may be achieved by electrically connecting the first sub-pixel electrode 411 and the second sub-pixel electrode 412 to the third sub-pixel electrode 421 and the fourth sub-pixel electrode 422 at the same layer as the pixel electrode 4, while the other two sub-pixel electrodes may not be connected at the same layer as the pixel electrode 4, but may be electrically connected through other structures, for example, both being connected to the same transistor drain. Specifically, for example, the first sub-pixel electrode 411 and the third sub-pixel electrode 421 may be electrically connected at the same layer as the pixel electrode 4, and both exhibit one brightness; while the second sub-pixel electrode 412 and the third sub-pixel electrode 421 may not be electrically connected at the same layer as the pixel electrode 4, but may be electrically connected to the same transistor drain (i.e., through the drain layer), and both exhibit a different brightness. The brightness of the two sub-pixel electrodes connected at the same layer as the pixel electrode 4 may be different from the brightness of the other two sub-pixel electrodes.
[0253] It can be understood that the brightness of the two connected together is different from the brightness of the other two, and refers to the brightness comparison within a sub-pixel when the display panel is powered on and lit.
[0254] In a possible embodiment, in combination with Figures 1A-1G, 2A-2G, 3A-3G, 4A-4G, 5A-5G, and 6A-6G, the array substrate further includes: a plurality of transistors T; a plurality of transistors electrically connected to the same pixel electrode 4, all electrically connected to the same data line 3 and the same gate line 2. For example, as shown in Figure 1B, there are three transistors electrically connected to the same pixel electrode 4, namely a first transistor T1, a second transistor T2, and a third transistor T3, and the three transistors are all electrically connected to the same data line 3 and the same gate line 2; the second sub-pixel electrode 412 is located on a side of the first sub-pixel electrode 411 away from the electrically connected data line 3, and the fourth sub-pixel electrode 422 is located on a side of the third sub-pixel electrode 421 away from the electrically connected data line 3; the first sub-pixel electrode 411 is electrically connected to the fourth sub-pixel electrode 422. Specifically, the first sub-pixel electrode 411 and the fourth sub-pixel electrode 422 are electrically connected at the same layer as the pixel electrode 4, and the second sub-pixel electrode 412 and the third sub-pixel electrode 421 are both electrically connected to the second electrode TC of the second transistor T2. In the disclosed embodiment, the first sub-pixel electrode 411 and the fourth sub-pixel electrode 422 are electrically connected at the pixel electrode 4, and the second sub-pixel electrode 412 and the third sub-pixel electrode 421 are electrically connected. That is, the four portions of the pixel electrode 4 are cross-connected in pairs, which facilitates the formation of an eight-domain distribution within the same pixel electrode 4.
[0255] It should be noted that the multiple transistors electrically connected to the same pixel electrode 4 may refer to being electrically connected to the same pixel electrode 4 directly or indirectly. For example, the first transistor T1 and the second transistor T2 may be directly electrically connected to the pixel electrode 4, and the third transistor T3, since it is electrically connected to the second transistor T2, may also be considered to be electrically connected to the pixel electrode 4. Specifically, the multiple transistors electrically connected to the same pixel electrode 4 may also be transistors that drive the same pixel electrode 4.
[0256] In a possible embodiment, as shown in FIG. 1A to FIG. 1G , the array substrate further includes: a first signal line 5 extending along a second direction Y; the plurality of transistors T include: a first transistor T1 , a second transistor T2 , and a third transistor T3 ;
[0257] The control electrode TA of the first transistor T1 is electrically connected to the gate line 2, the first electrode TB of the first transistor T1 is electrically connected to the data line 3, and the second electrode TC of the first transistor T1 is electrically connected to the first sub-pixel electrode 411 and the fourth sub-pixel electrode 422. Specifically, the second electrode TC of the first transistor T1 can be electrically connected to the first sub-pixel electrode 411 and the fourth sub-pixel electrode 422 through the first via hole K1.
[0258] The control electrode TA of the second transistor T2 is electrically connected to the gate line 2, the first electrode TB of the second transistor T2 is electrically connected to the data line 3, and the second electrode TC of the second transistor T2 is electrically connected to the second sub-pixel electrode 412 and the third sub-pixel electrode 421. Specifically, the second electrode TC of the second transistor T2 can be electrically connected to the third sub-pixel electrode 421 through a second via hole K2; the second electrode TC of the second transistor T2 can be electrically connected to the second sub-pixel electrode 412 through a third via hole K3.
[0259] The control electrode TA of the third transistor T3 is electrically connected to the gate line 2 , the first electrode TB of the third transistor T3 multiplexes the second electrode TC of the second transistor T2 , and the second electrode TC of the third transistor T3 multiplexes the first signal line 5 .
[0260] Figure 9 may be an equivalent circuit diagram corresponding to Figure 1B, wherein S is the data line on the left side of the pixel, that is, the signal line for transmitting the data signal of the current sub-pixel, that is, the data line electrically connected to the current sub-pixel, S is the data line on the right side of the pixel, and is also the data line of the horizontally adjacent pixel.

This facilitates electrical connection between the first transistor first portion T1C1 and the first sub-pixel electrode protrusion 41A via the first via K1.
[0276] In one possible embodiment, as shown in Figures 1A-1G, the second electrode TC of the first transistor T1 includes: a first transistor second portion T1C2 extending along the second direction Y and electrically connected to the first transistor first portion T1C1; specifically, the orthographic projection of the first transistor second portion T1C2 on the substrate 1 may have an overlapping area with the orthographic projection of the active pattern 6 on the substrate 1.

Because the second portion T2C2 of the second transistor overlaps with the gate line 2, a coupling capacitor is formed therebetween. The second sub-pixel electrode extension 42B covers a portion of the second portion T2C2 of the second transistor, thereby shielding a portion of the coupling capacitor between the second portion T2C2 of the second transistor and the gate line 2. Furthermore, at least a portion of the orthographic projection of the second portion T2C2 of the second transistor on the substrate 1 overlaps with at least a portion of the orthographic projection of the second sub-pixel electrode extension 42B on the substrate 1.

[0368] Based on the same inventive concept, an embodiment of the present disclosure further provides a display panel, which includes: an array substrate as provided in the embodiment of the present disclosure, and also includes an opposite substrate arranged opposite to the array substrate, wherein the opposite substrate is provided with a common electrode layer.
[0369] In a possible embodiment, referring to FIG10 and FIG8 , the display panel further includes a liquid crystal layer 10 located between the array substrate and the counter substrate; the liquid crystal layer 10 includes: a plurality of liquid crystal portions PJ, at least one liquid crystal portion PJ of the plurality of liquid crystal portions PJ includes: a first sub-liquid crystal portion PJ1, a second sub-liquid crystal portion PJ2, a third sub-liquid crystal portion PJ3, and a fourth sub-liquid crystal portion PJ4; an orthographic projection of the liquid crystal portion PJ on the substrate 1 overlaps with an orthographic projection of the pixel electrode 4 on the substrate 1; an orthographic projection of the first sub-liquid crystal portion PJ1 on the substrate 1 overlaps with an orthographic projection of the first sub-electrode portion P1 on the substrate 1; an orthographic projection of the second sub-liquid crystal portion PJ2 on the substrate 1 overlaps with an orthographic projection of the second sub-electrode portion P2 on the substrate 1; an orthographic projection of the third sub-liquid crystal portion PJ3 on the substrate 1 overlaps with an orthographic projection of the third sub-electrode portion P3 on the substrate 1; and an orthographic projection of the fourth sub-liquid crystal portion PJ4 on the substrate 1 overlaps with an orthographic projection of the fourth sub-electrode portion P4 on the substrate 1;
[0370] The initial alignment directions of the first sub-liquid crystal portion PJ1 , the second sub-liquid crystal portion PJ2 , the third sub-liquid crystal portion PJ3 , and the fourth sub-liquid crystal portion PJ4 are different from each other.
[0371] It is understandable that the initial alignment direction of the liquid crystal may be the alignment direction of the liquid crystal when no voltage is applied.
[0372] In a possible embodiment, as shown in Figure 8, the angle range between the initial alignment direction of the first sub-liquid crystal portion PJ1 and the first direction X is 210°~240°; the angle range between the initial alignment direction of the second sub-liquid crystal portion PJ2 and the first direction X is 120°~150°; the angle range between the initial alignment direction of the third sub-liquid crystal portion PJ3 and the first direction X is 300°~330°; the angle range between the initial alignment direction of the fourth sub-liquid crystal portion PJ4 and the first direction X is 30°~60°.
[0373] In a possible embodiment, as shown in Figure 8, the alignment direction of at least part of the liquid crystal at the junction of the first sub-liquid crystal portion PJ1 and the second sub-liquid crystal portion PJ2 is opposite to the alignment direction of at least part of the liquid crystal at the junction of the third sub-liquid crystal portion PJ3 and the fourth sub-liquid crystal portion PJ4.
[0374] In one possible embodiment, as shown in FIG8 , the liquid crystal at the junction of the first and second liquid crystal sub-sections PJ1 and PJ2 is aligned parallel to the first direction X and faces leftward. The liquid crystal at the junction of the third and fourth liquid crystal sub-sections PJ3 and PJ4 is aligned parallel to the first direction X and faces rightward. Compared to the conventional SUVA structure shown in FIG7 , which lacks a good liquid crystal angle to compensate for left and right viewing angles, all lateral liquid crystals face rightward, with no lateral liquid crystals facing leftward. In the disclosed embodiment, as shown in FIG8 , the lateral liquid crystals face both leftward and rightward, allowing the left and right lateral liquid crystals to compensate for each other's viewing angles, thereby improving left-right color shift.

[0376] In one possible embodiment, as shown in Figure 10, the first conductive layer 7 is located on the side of the pixel electrode 4 away from the opposite substrate. In this public embodiment, the first conductive layer 7 is located on the side of the pixel electrode 4 away from the opposite substrate, which can isolate (or shield) the first overlapping capacitance between the pixel electrode 4 and the gate line 2 and the second overlapping capacitance between the pixel electrode 4 and the data line 3, greatly reducing the risk of crosstalk. At the same time, due to the presence of the first conductive layer 7, the distance between the pixel electrodes 4 can be reduced, so that the pixel electrode 4 and the gate line 2 overlap (overlap), the pixel electrode 4 and the data line 3 overlap (overlap), reducing the risk of liquid crystal light leakage, thereby reducing the width of the black matrix, increasing the pixel aperture ratio, and improving the pixel transmittance.
