This application claims priority to Chinese Patent Application No. 201710114666.3 filed in China on Feb. 28, 2017, the entire contents of which are hereby incorporated by reference.
The present disclosure relates to the field of display technology and, more particularly, to an array substrate, a method of manufacturing the same, a display panel and a display device.
With development of display technology, a liquid crystal display has gradually replaced a traditional CRT display and becomes mainstream of the panel display. In the liquid crystal display technology field, a TFT-LCD (Thin Film Transistor Liquid Crystal Display) has been widely used in fields of television sets, computers, mobile phones and the like by virtue of its large size, flexible process, excellent performance and low cost.
As one of main parts of the TFT-LCD, the display panel generally includes an array substrate, a color film substrate, and liquid crystals between the array substrate and the color film substrate. In the array substrate, a plurality of crisscross gate lines and data lines intersect to define a plurality of pixel units. In the prior art, a gap between the gate line and the pixel unit may cause a halo in periphery of the gate line when the display panel is operating normally. In this case, a BM (Black Matrix) is usually used to cover the halo. However, the larger a BM width is, the smaller a light transmission region under the same display area will be, which is disadvantageous to the development requirement of the high aperture ratio of the liquid crystal display panel.
In view of this, a novel array substrate, a method of manufacturing the same, a display panel and a display device are required.
It should be noted that, information disclosed in the above background portion is provided only for better understanding of the background of the present disclosure, and thus it may contain information that does not form the prior art known by those ordinary skilled in the art.

Referring to
W20′=Wgate+2*a+2*m
where Wgate denotes a width of the gate line 17, a denotes a width of the halo 300 formed between the gate line 17 and one sub-pixel, and m denotes an assay margin of the display panel.
Since a distance between every adjacent two sub-pixel rows in
WBM′=3*W20′=3*Wgate+3*2*a+3*2*m
The present disclosure provides a novel array substrate, including: a plurality of pixel units, the plurality of pixel units being arranged in rows and columns and each row of the pixel units including a first sub-pixel row, a second sub-pixel row and a third sub-pixel row being adjacent successively; and a plurality of gate lines, each of the gate lines being configured to drive one sub-pixel row, and gate lines for driving the first sub-pixel row and the second sub-pixel row in a same pixel unit being located between the first sub-pixel row and the second sub-pixel row in the pixel unit.
By arranging gate lines for driving the first sub-pixel row and the second sub-pixel row in the same pixel unit to be between the first sub-pixel row and the second sub-pixel row in the pixel unit, the width of the BM of the display panel is reduced, an aperture ratio is increased, and the light transmission efficiency is improved.
Corresponding to the array substrate as shown in
In an exemplary embodiment of the present disclosure, the first sub-pixel row may be a first color sub-pixel row. The second sub-pixel row may be a second color sub-pixel row and the third sub-pixel row may be a third color sub-pixel row. It should be understood that, terms “first”, “second” and “third” as used in the present disclosure are not limiting of the sub-pixel rows. In other words, in another embodiment of the present disclosure, the first sub-pixel row may be termed as the third sub-pixel row, and the third sub-pixel row may be termed as the first sub-pixel. In addition, colors of different sub-pixel rows may also be changed, and in the embodiment where one pixel unit is composed of three sub-pixels, the three colors may be R (red), G (green), and B (blue), respectively.
In view of this, the second sub-pixel row 13 as shown in
The length of the dotted line BB′ in
W20=2*Wgate+b+2*a+2*m
where b is a distance between the gate line 173 and the gate line 175.
According to some embodiments of the present disclosure, the distance between the first sub-pixel row 11 and the second sub-pixel row 13 as shown in
WBM=3*Wgate+b+c+2*2*a+2*2*m
As described above, the BM width of the array substrate according to the exemplary embodiment of the present disclosure is reduced by a width value d as compared with the BM width of the above-described array substrate, wherein:
In an exemplary embodiment of the present disclosure, the width value may be averaged to each sub-pixel row, so the BM width may be reduced by d/3 as for each sub-pixel row.
In an ADS (Advanced Super Dimension Switch) type liquid crystal display device, a width “a” of the halo 300 may be about 15 μm, an assay margin m may be between 6 μm and 7 μm, a distance “b” between two gate lines may be between about 6 μm and about 7 μm, and a distance “c” between the first sub-pixel row 11 and the second sub-pixel row 13 may be between about 3 μm and 5 μm. In this case, as for an array substrate consisting of one pixel unit in a longitudinal direction and three pixel units in a horizontal direction, the BM width of the exemplary embodiment of the present disclosure is reduced by about 30 μm to about 35 μm as compared with the prior art. In addition, being averaged to each sub-pixel row, the BM width may be reduced by at least about 10 μm.
As described above, the array substrate according to the exemplary embodiment of the present disclosure may achieve a smaller BM width, and on this basis, the aperture ratio is increased and the light transmission efficiency is improved.
According to other embodiments of the present disclosure, each row of the pixel units further includes a fourth sub-pixel row adjacent to the third sub-pixel row. In the embodiment, the fourth sub-pixel row may be a fourth color sub-pixel row. In an embodiment in which one pixel unit is composed of four sub-pixels, the four colors may be R (red), G (green), B (blue), and W (white), respectively, but not limited thereto. The four colors may also be R (red), G (green), B (blue), and Y (yellow), which is not particularly limited by the present exemplary embodiment.
In addition, in an array substrate including sub-pixel rows having four colors, gate lines for driving the first sub-pixel row and the second sub-pixel row in a same pixel unit are located between the first sub-pixel row and the second sub-pixel row in the pixel unit, and gate lines for driving the third sub-pixel row and the fourth sub-pixel row in a same pixel unit are located between the third sub-pixel row and the fourth sub-pixel row in the pixel unit. In this case, the width of the BM is also reduced. The specific calculation process is similar to the above calculation process, which will not be repeated herein.
Each row of pixel units arranged in the horizontal direction includes a first sub-pixel row 11, a second sub-pixel row 13, a third sub-pixel row 15, and a gate line 171, a gate line 173, a gate line 175 for driving the first sub-pixel row 11, the second sub-pixel row 13 and the third sub-pixel row 15, respectively. This structure is similar to that shown in
In addition, the array substrate may further include a plurality of data lines 19. In the pixel array arranged in a manner of a plurality of pixel units in the longitudinal direction and a plurality of pixel units in the horizontal direction, the data line 19 may be configured to provide a data signal to sub-pixels of an n-th column, and the data line 19 is located between the sub-pixels of the n-th column and a column of sub-pixels adjacent thereto, n being a positive integer.

In addition, the array substrate shown in
At this time, the first data line 191 and the second data line 192 are adjacent and both located between the n-th column sub-pixels and the (n+1)-th column sub-pixels. In addition, there may be no data lines between the (n+1)-th column sub-pixels and the (n+2)-th column sub-pixels.
In addition, the array substrate shown in
The main difference between the structure of the array substrate shown in
In an exemplary embodiment of the present disclosure, there is further provided an array substrate including pixel units having four sub-pixels. Referring to
In the present embodiment, both a gate line 171 for driving the first sub-pixel row 11 and a gate line 173 for driving the second sub-pixel row 13 are located between the first sub-pixel row 11 and the second sub-pixel row 15. Both a gate line 175 for driving the three sub-pixel row 15 and a gate line 178 for driving the fourth sub-pixel row 18 are located between the third sub-pixel row 15 and the fourth sub-pixel row 18.
In addition, the array substrate shown in
In addition, as shown in
It will be understood by those skilled in the art that, other arrangements of the data lines are present in the present disclosure. For example, in units of pixel units, different data lines may be used to provide data signals to different pixel units, respectively. In addition, equivalents of the above-described schemes should be construed as falling within the conception of the present disclosure.
Further, in the present exemplary embodiment, there is further provided a method of manufacturing an array substrate, including: forming a plurality of pixel units arranged in rows and columns, wherein each row of the pixel units includes a first sub-pixel row, a second sub-pixel row and a third sub-pixel row being adjacent successively; and forming a plurality of gate lines, wherein each of the gate lines is configured to drive one sub-pixel row, and gate lines for driving the first sub-pixel row and the second sub-pixel row in a same pixel unit are configured to be located between the first sub-pixel row and the second sub-pixel row in the pixel unit.
Further, in the present exemplary embodiment, there is further provided a display panel including the array substrate described above.
Further, in the present exemplary embodiment, there is further provided a display device which may include the display panel described above. The display device may be a product or a part having any display function such as a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a digital photo frame, a navigator, or the like.
The array substrate, display panel and display device provided by the present disclosure may achieve a smaller BM width, thus increasing the aperture ratio and improving the light transmission efficiency.
In a technical solution provided by some embodiments of the present disclosure, gate lines for driving the first sub-pixel row and the second sub-pixel row in a same pixel unit are configured to be located between the first sub-pixel row and the second sub-pixel row in the pixel unit, which reduces a width of a BM in an array substrate, increases the aperture ratio and improves the light transmission efficiency.
