To describe technical solutions of the embodiments of the present disclosure more clearly, the accompanying drawings of the embodiments will be briefly introduced in the following. It should be known that the accompanying drawings in the following description merely involve some embodiments of the present disclosure, but do not limit the present disclosure, in which.

In the accompanying drawings, numerals whose last two digits are the same correspond to the same elements. It is to be noted that the elements in the accompanying drawings are exemplary and are not drawn to scale.

To make the technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below, in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are merely some but not all of the embodiments of the present disclosure.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which present disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. As used herein, the description of "connecting" or "coupling" two or more parts together should refer to the parts being directly combined together or being combined via one or more intermediate components. In addition, terms such as "first" and "second" are only used to distinguish one element (or a part of the element) from another element (or another part of this element).

An array substrate for a display device includes a plurality of gate lines arranged in a direction parallel to the sub-pixel rows and a plurality of data lines perpendicular to the gate lines. At each side of each sub-pixel row, one gate line dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line is arranged every two sub-pixels. On such an array substrate, widths of black matrixes between adjacent sub-pixels are different, and such a phenomenon is referred to as a black matrix difference. The embodiments of the present disclosure are described by taking the above array substrate as an example. However, the protection scope of the present disclosure is not limited to the array substrate. That is, other types of array substrates may also be included.

<FIG> is a schematic diagram schematically illustrating black matrix difference. As shown in <FIG>, in a row direction, a width of the black matrix at the left of a sub-pixel R is AA', and the width of the black matrix at the right of the sub-pixel R is BB'. The black matrix of width AA' is configured to shelter a data line, and thus its width is set according to a design rule of the black matrix. The black matrix of width BB' is configured to shelter a common electrode, and thus its width may be adjusted within a certain range. The narrower the black matrix of width BB' is, the greater the black matrix difference (namely, (AA'- BB')/ the width between the two sub-pixels) is. In this way, the aperture ratio increases, but the brightness distribution difference between the two pixels also increases, thereby causing pixel display difference when displaying images of low gray scale. That is, a phenomenon of periodic vertical stripes (such as light and dark stripes on a white image) may occur in the case of viewing the displayed image on a screen from different distances at different angles.

<FIG> illustrates a schematic structural diagram of an array substrate adopting a basic pixel structure. As shown in <FIG>, the pixel structure having the sub-pixels of the same color on different sub-pixel rows being aligned with one another is referred to as a "basic pixel structure" hereinafter. The array substrate as shown in <FIG> includes a plurality of gate lines <NUM> arranged in a direction parallel to the sub-pixel rows, a plurality of data lines <NUM> perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate as shown in <FIG>, at each side of each sub-pixel row, one gate line <NUM> dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line <NUM> is arranged every two sub-pixels. A first shelter <NUM> (namely, the black matrix of width AA' in <FIG>) is configured to shelter the data line <NUM>, and thus its width is set according to a design rule of the black matrix. Whereas a second shelter <NUM> (namely, the black matrix of width BB' in <FIG>) is configured to shelter a common electrode, and thus its width may be adjusted within a certain range. As shown in <FIG>, the first shelters <NUM> on different sub-pixel rows are aligned with each other, and the second shelters <NUM> on different sub-pixel rows are aligned with one another.

<FIG> illustrates a schematic structural diagram of an array substrate adopting a Bright View <NUM> (BV3) pixel structure. The array substrate includes a plurality of gate lines <NUM> arranged in a direction parallel to the sub-pixel rows, a plurality of data lines <NUM> perpendicular to the gate lines, and a plurality of common electrodes <NUM>. On the array substrate, at each side of each sub-pixel row, one gate line <NUM> dedicated to the sub-pixel row is respectively arranged. In each sub-pixel row, one data line <NUM> is arranged every two sub-pixels. The common electrode <NUM> is positioned between the two sub-pixels. The pixel structure having the sub-pixel rows adjacent to each other as shown in <FIG> being arranged as deviating from each other by a half of the width of the sub-pixel, and having the sub-pixels of the same color on the sub-pixel rows arranged in one other line being aligned with one another is referred to as a "BV3 pixel structure". The array substrate having such a structure includes a plurality of pixel groups <NUM> arranged along a column direction. As shown in <FIG>, in a BV3 pixel structure, each pixel group <NUM> includes two sub-pixel rows <NUM>. The sub-pixel rows adjacent to each other are arranged in a staggered manner, and thus the first shelters <NUM> and the second shelters <NUM> on different sub-pixel rows <NUM> are not aligned with one another. However, since each pixel group <NUM> is identical in structure and aligned with one another, the first shelters <NUM> on the first sub-pixel row <NUM> of one pixel group <NUM> are aligned with the first shelters <NUM> on the first sub-pixel rows <NUM> of other pixel groups <NUM>. The second shelters <NUM> on the first sub-pixel row <NUM> of one pixel group <NUM> are aligned with the second shelters <NUM> on the first sub-pixel rows <NUM> of other pixel groups <NUM>. The first shelters <NUM> on the second sub-pixel row <NUM> of one pixel group <NUM> are aligned with the first shelters <NUM> on the second sub-pixel rows <NUM> of other pixel groups <NUM>. The second shelters <NUM> on the second sub-pixel row <NUM> of one pixel group <NUM> are aligned with the second shelters <NUM> on the second sub-pixel rows <NUM> of other pixel groups <NUM>.

The array substrate adopting the above two types of pixel structures (the basic pixel structure and the BV3 pixel structure) has the problem of pixel display difference when displaying image of low gray scale. One solution is to increase the width of the second shelter so as to reduce the black matrix difference. However, this solution may sacrifice the aperture ratio.

An embodiment of the present disclosure provides a new-type array substrate, which can avoid pixel display difference when displaying images of low gray scale, without reducing an aperture ratio. <FIG> illustrates a schematic structural diagram of an array substrate useful for understanding the present invention. The array substrate includes a plurality of gate lines <NUM> arranged in a direction parallel to the sub-pixel rows, a plurality of data lines <NUM> perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate, at each side of each sub-pixel row, one gate line <NUM> dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line <NUM> is arranged every two sub-pixels <NUM>. The array substrate includes a plurality of pixel groups <NUM> arranged along a column direction. Each pixel group <NUM> is identical in structure and aligned with one another. Each pixel group <NUM> includes a plurality of sub-pixel rows <NUM>. A first shelter <NUM> or a second shelter <NUM> is arranged alternately between two adjacent sub-pixels <NUM> in each sub-pixel row <NUM>. For each pixel group <NUM>, the first shelters <NUM> on at least one of the sub-pixel rows <NUM> are aligned with the second shelters <NUM> on at least one of another sub-pixel rows <NUM>. The first shelter <NUM> has a first width, and the second shelter <NUM> has a second width.

In one example, the first shelter <NUM> is configured to shelter a data line <NUM>, and the second shelter <NUM> is configured to shelter a common electrode (not shown). The width of the common electrode is less than that of the data line <NUM>, and thus the width of the second shelter <NUM> is less than that of the first shelter <NUM>.

In the case that the width of the first shelter <NUM> is different from that of the second shelter <NUM>, the array substrate can avoid, by changing the arrangement of the first shelter <NUM> and the second shelter <NUM> such that the brightness distribution difference between the pixels in a column direction is reduced, pixel display difference when displaying images of low gray scale, without reducing an aperture ratio.

Exemplary embodiments of the present disclosure will be described below with respect to different pixel structures.

<FIG> illustrates a schematic structural diagram of an array substrate adopting a basic pixel structure useful for understanding the present invention. The array substrate includes a plurality of gate lines <NUM> arranged in a direction parallel to the sub-pixel rows, a plurality of data lines <NUM> perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate, at each side of each sub-pixel row, one gate line <NUM> dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line <NUM> is arranged every two sub-pixels. Each pixel group <NUM> includes two sub-pixel rows <NUM>. A first shelter <NUM> or a second shelter <NUM> is arranged alternately between two adjacent sub-pixels <NUM> in each sub-pixel row <NUM>. The first shelter <NUM> has a first width, and the second shelter <NUM> has a second width. The first shelters <NUM> on one sub-pixel row <NUM> are aligned with the second shelters <NUM> on the other sub-pixel row <NUM>, and the second shelters <NUM> on the sub-pixel row <NUM> are aligned with the first shelters <NUM> on the other sub-pixel row <NUM>. That is, on the array substrate, the first shelters <NUM> and the second shelters <NUM> are also arranged alternately in the column direction. Therefore, the number of the first shelters <NUM> is equal to that of the second shelters <NUM> in each column of shelters, thereby ensuring a uniform brightness distribution among the sub-pixel columns. Therefore, pixel display difference when displaying images of low gray scale can be avoided, without reducing an aperture ratio.

In this array substrate, the first shelter <NUM> is configured to shelter the data line <NUM>. The first shelters <NUM> and the second shelters <NUM> are arranged alternately in the column direction. Therefore, on the array substrate, as shown in <FIG>, the data lines <NUM> has a shape like letter 'Z'. The Z-shaped routing mode may increase a line resistance, and thus a voltage of a data signal transmitted over the data line <NUM> may be affected.

An exemplary embodiment of the present disclosure provides another array substrate adopting the basic pixel structure. In the array substrate, each pixel group includes more than two sub-pixel rows. <FIG> illustrates a schematic structural diagram of an array substrate adopting the basic pixel structure according to this exemplary embodiment of the present disclosure. The array substrate includes a plurality of gate lines <NUM> arranged in a direction parallel to the sub-pixel rows <NUM>, a plurality of data lines <NUM> perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate, at each side of each sub-pixel row <NUM>, one gate line <NUM> dedicated to the sub-pixel row <NUM> is arranged. In each sub-pixel row <NUM>, one data line <NUM> is arranged every two sub-pixels <NUM>. Each pixel group <NUM> may include more than two sub-pixel rows <NUM>. Each pixel group <NUM> is divided, in the column direction, into a first pixel subgroup 600A and a second pixel subgroup 600B. The first pixel subgroup 600A may include N sub-pixel rows <NUM>, whereas the second pixel subgroup 600B may include M sub-pixel rows <NUM>. In each pixel subgroup, the first shelters <NUM> on different sub-pixel rows <NUM> are aligned with one another, and the second shelters <NUM> on different sub-pixel rows <NUM> are aligned with one another. The first shelters <NUM> on each sub-pixel row <NUM> in the first pixel subgroup 600A are aligned with the second shelters <NUM> on each sub-pixel row <NUM> in the second pixel subgroup 600B. The second shelters <NUM> on each sub-pixel row <NUM> in the first pixel subgroup 600A are aligned with the first shelters <NUM> on each sub-pixel row <NUM> in the second pixel subgroup 600B. In one example, the N and the M may be any value from one to four, and the N may be equal to the M.

This exemplary embodiment is described in more detail below by taking an example in which each pixel group <NUM> includes four sub-pixel rows <NUM>. Each pixel group <NUM> is divided, in the column direction, into a first pixel subgroup 600A and a second pixel subgroup 600B. The first pixel subgroup 600A includes a first sub-pixel row <NUM> and a second sub-pixel row <NUM>. The second pixel subgroup 600B includes a third sub-pixel row <NUM> and a fourth sub-pixel row <NUM>. In the first pixel subgroup 600A, the first shelters <NUM> on the first sub-pixel row <NUM> and the second sub-pixel row <NUM> are aligned with one another, and the second shelters <NUM> on the first sub-pixel row <NUM> and the second sub-pixel row <NUM> are aligned with one another. In the second pixel subgroup 600B, the first shelters <NUM> on the third sub-pixel row <NUM> and the fourth sub-pixel row <NUM> are aligned with one another, and the second shelters <NUM> on the third sub-pixel row <NUM> and the fourth sub-pixel row <NUM> are aligned with one another. Furthermore, the first shelters <NUM> on the first sub-pixel row <NUM> and the second sub-pixel row <NUM> are aligned with the second shelters <NUM> on the third sub-pixel row <NUM> and the fourth sub-pixel row <NUM>. The second shelters <NUM> on the first sub-pixel row <NUM> and the second sub-pixel row <NUM> are aligned with the first shelters <NUM> on the third sub-pixel row <NUM> and the fourth sub-pixel row <NUM>.

Adopting the arrangement according to this exemplary embodiment may ensure a uniform brightness distribution among sub-pixel columns. Therefore, in this embodiment, pixel display difference when displaying images of low gray scale can be avoided, without reducing the aperture ratio. Because the Z-shaped routings of the data lines are reduced, in this embodiment the line resistances of the data lines can also be reduced with respect to the exemplary embodiment in <FIG>.

<FIG> illustrates a schematic structural diagram of an array substrate adopting a BV3 pixel structure according to yet another exemplary embodiment of the present disclosure. The array substrate includes a plurality of gate lines <NUM> arranged in a direction parallel to the sub-pixel rows, a plurality of data lines <NUM> perpendicular to the gate lines, and a plurality of common electrodes <NUM>. On the array substrate, at each side of each sub-pixel row, one gate line <NUM> dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line <NUM> is arranged every two sub-pixels. The common electrode <NUM> is positioned between the two sub-pixels. Each pixel group <NUM> includes four sub-pixel rows <NUM>. Each pixel group <NUM> is divided, in the column direction, into a first pixel subgroup 700A and a second pixel subgroup 700B. The first pixel subgroup 700A includes sub-pixel rows <NUM> on odd lines. The second pixel subgroup 700B includes sub-pixel rows <NUM> on even lines. In one pixel subgroup (for example, the first pixel subgroup 700A) of the first pixel subgroup 700A and the second pixel subgroup 700B, the first shelters <NUM> on one sub-pixel row <NUM> are aligned with the second shelters <NUM> on the other sub-pixel row <NUM>, and the second shelters <NUM> on the one sub-pixel row <NUM> are aligned with the first shelters <NUM> on the other sub-pixel row <NUM>. In the other pixel subgroup (for example, the second pixel subgroup 700B) of the first pixel subgroup 700A and the second pixel subgroup 700B, the first shelters <NUM> on different sub-pixel rows <NUM> are aligned with one another, and the second shelters <NUM> on different sub-pixel rows <NUM> are aligned with one another. Such an arrangement can avoid pixel display difference when displaying images of low gray scale, without reducing the aperture ratio.

<FIG> is a schematic diagram illustrating a design of the array substrate as shown in <FIG>. In order to facilitate understanding, like reference numerals refer to identical elements, parts or combination thereof in <FIG> and <FIG>.

<FIG> is a schematic diagram illustrating a design of an array substrate adopting a BV3 pixel structure according to still another exemplary embodiment of the present disclosure. Each pixel group <NUM> includes six sub-pixel rows <NUM>. Each pixel group <NUM> is divided, in the column direction, into a first pixel subgroup 900A and a second pixel subgroup 900B. The first pixel subgroup 900A includes sub-pixel rows <NUM> on odd lines. The second pixel subgroup 900B includes sub-pixel rows <NUM> on even lines. In one pixel subgroup (for example, the second pixel subgroup 900B) of the first pixel subgroup 900A and the second pixel subgroup 900B, the first shelters <NUM> on the middle sub-pixel row <NUM> are aligned with the second shelters <NUM> on the upper and lower sub-pixel rows <NUM>, and the second shelters <NUM> on the middle sub-pixel row <NUM> are aligned with the first shelters <NUM> on the upper and lower sub-pixel rows <NUM>. In the other pixel subgroup (for example, the first pixel subgroup 900A) of the first pixel subgroup 900A and the second pixel subgroup 900B, the first shelters <NUM> on the middle sub-pixel row <NUM> are aligned with the second shelters <NUM> on one sub-pixel row <NUM> of the upper and lower sub-pixel rows <NUM> and are aligned with the first shelters <NUM> on the other sub-pixel row <NUM> of the upper and lower sub-pixel rows <NUM>, and the second shelters <NUM> on the middle sub-pixel row <NUM> are aligned with the first shelters <NUM> on one sub-pixel row <NUM> of the upper and lower sub-pixel rows <NUM> and are aligned with the second shelters <NUM> on the other sub-pixel row <NUM> of the upper and lower sub-pixel rows <NUM>. Compared with the design of the exemplary embodiment in <FIG> and <FIG>, in the design of this exemplary embodiment, the arrangement of the first shelters <NUM> and the second shelters <NUM> are changed in both the first pixel subgroup 900A and the second pixel subgroup 900B. Therefore, pixel display difference when displaying images of low gray scale can be better avoided, without reducing the aperture ratio.

Those skilled in the art should understand that for the array substrate adopting the BV3 pixel structure, the number of the sub-pixel rows included in each pixel group may be more than six in variants or modifications of the exemplary embodiment in <FIG> and <FIG> and the exemplary embodiment in <FIG> of the present disclosure.
