Based on the same idea, the invention also provides a display device which comprises the array substrate provided by the invention.
Compared with the prior art, the array substrate and the display device provided by the invention at least realize the following beneficial effects:
the array substrate provided by the invention comprises a plurality of gate lines extending along a first direction and a plurality of data lines extending along a second direction, wherein the first direction and the second direction are crossed. The gate lines and the data lines are insulatively crossed to define a plurality of sub-pixels, and the sub-pixels arranged in each column along the second direction and two data lines adjacent thereto are alternately connected in odd and even rows. When the polarities of signals transmitted on two adjacent data lines are different, the polarities of two sub-pixels adjacent to each other in the first direction may be different, and the polarities of two sub-pixels adjacent to each other in the second direction may also be different. That is to say, the array substrate provided by the invention can realize the dot inversion of the polarity of the sub-pixels in a column inversion mode, thereby reducing the flicker of pictures. The array substrate further comprises a plurality of touch lines extending along the second direction, a touch line is arranged between every two adjacent rows of sub-pixels arranged along the second direction, and the touch lines and the data lines are arranged on the same layer, so that the thickness of the array substrate is reduced. The data lines comprise a first data line and a second data line, and the first data line and the second data line are respectively positioned at two sides of the sub-pixels arranged in the same column along the second direction along the first direction. The sub-pixels comprise a first sub-pixel and a second sub-pixel, the first sub-pixel and the second sub-pixel are adjacently arranged along a second direction, the first sub-pixel is electrically connected with the first data line, and the second sub-pixel is electrically connected with the second data line. A touch line is arranged between the first sub-pixel and the first data line. The first sub-pixel comprises a first thin film transistor, the first thin film transistor comprises a first active portion, and a touch control line is arranged between the first sub-pixel and the first data line, so that the first active portion is partially overlapped with the touch control line along the direction perpendicular to the plane of the array substrate. The second sub-pixel comprises a second thin film transistor which comprises a second active part, and because no touch control line is arranged between the second sub-pixel and the second data line, the second active part is not overlapped with the touch control line along the direction vertical to the plane of the array substrate. The first active part in the first thin film transistor needs to extend across the touch control line to be electrically connected with the first sub-pixel, and the second active part in the second thin film transistor does not need to extend across the touch control line to be directly electrically connected with the second sub-pixel, so that the arrangement length of the first active part in the first thin film transistor is longer than that of the second active part in the second thin film transistor. In the direction perpendicular to the plane of the array substrate, the first active portion of the first thin film transistor is partially overlapped with the touch control line, and the second active portion of the second thin film transistor is not overlapped with the touch control line TP, so that a coupling capacitor is formed between the first active portion of the first thin film transistor and the touch control line. Therefore, when the first sub-pixel and the second sub-pixel have the same structure, the light-emitting brightness of the first sub-pixel electrically connected with the first active portion in the first thin film transistor is smaller than that of the second sub-pixel electrically connected with the second active portion in the second thin film transistor, that is, the light-emitting brightness of the first sub-pixel electrically connected with the first active portion in the first thin film transistor is different from that of the second sub-pixel electrically connected with the second active portion in the second thin film transistor, so that the display effect is affected. According to the invention, the brightness control parameter of the first sub-pixel is different from that of the second sub-pixel, so that different brightness control parameters can be selected according to the brightness difference of the first sub-pixel and the second sub-pixel, the brightness difference of the first sub-pixel and the second sub-pixel is effectively improved, and the display effect is effectively improved.

The sub-pixels 4 arranged in the second direction Y in each column are alternately connected with the two data lines 2 adjacent thereto in odd and even rows, thereby facilitating dot inversion of the polarities of the sub-pixels by means of column inversion. The array substrate further comprises a plurality of touch control lines 3 extending along the second direction Y, the touch control lines 3 and the data lines 2 are arranged in the same layer, so that the lengths of the active parts 5 in two adjacent sub-pixels 4 along the second direction Y are different, the active part 5 and the touch control line 3 in one sub-pixel 4 are partially overlapped in the direction perpendicular to the plane where the array substrate is located, and the active part 5 and the touch control line 3 in the other sub-pixel 4 are not overlapped in the direction perpendicular to the plane where the array substrate is located, so that the brightness of the two sub-pixels is different, and the display effect is influenced.
Based on the research, the application provides an array substrate and display device, effectively improves display effect. The array substrate having the above technical effects provided by the present application is described in detail as follows:
fig. 2 is a schematic partial plan view of an array substrate provided by the present invention, and referring to fig. 2, the present embodiment provides an array substrate including a plurality of gate lines G extending along a first direction X and a plurality of data lines D extending along a second direction Y, where the first direction X and the second direction Y intersect. Optionally, the first direction X and the second direction Y are perpendicular. The gate lines G and the data lines D are insulated and crossed to define a plurality of sub-pixels P10, and the sub-pixels P10 arranged in each column along the second direction Y and two data lines D adjacent thereto are alternately connected in odd and even rows. When the polarities of signals transmitted on two adjacent data lines D are different, the polarities of two sub-pixels P10 adjacent in the first direction X may be made different, and at the same time, the polarities of two sub-pixels P10 adjacent in the second direction Y may be made different. That is to say, the array substrate provided in this embodiment may implement Dot inversion (Dot inversion) of the polarity of the sub-pixel P10 in a Column inversion (Column inversion) manner, so as to reduce flicker of the picture.
The array substrate further comprises a plurality of touch control lines TP extending along the second direction Y, one touch control line TP is arranged between two adjacent rows of sub-pixels P10 arranged along the second direction Y, and the touch control lines TP and the data lines D are arranged on the same layer, so that the thickness of the array substrate is favorably reduced.
The data line D includes a first data line D1 and a second data line D2, and the first data line D1 and the second data line D2 are respectively located at two sides of the same column of sub-pixels P10 arranged along the second direction Y along the first direction X. That is, two data lines D adjacent to the same column of the sub-pixels P10 arranged in the second direction Y are the first data line D1 and the second data line D2, respectively.
The subpixel P10 includes a first subpixel P11 and a second subpixel P12, the first subpixel P11 and the second subpixel P12 are adjacently disposed along the second direction Y, the first subpixel P11 is electrically connected to the first data line D1, and the second subpixel P12 is electrically connected to the second data line D2. That is, the first and second sub-pixels P11 and P12 adjacently disposed in the second direction Y are electrically connected to the first and second data lines D1 and D2, respectively.
It should be noted that, in the present invention, it is not limited that one data line D only can be a first data line or a second data line, and the names of the first data line and the second data line are only used for convenience of describing the connection relationship between the data line D and the sub-pixel P10. Similarly, in the present invention, it is not limited that one sub-pixel P10 can only be a first sub-pixel or a second sub-pixel, and the designation of the first sub-pixel or the second sub-pixel is only for convenience of describing the connection relationship between the data line D and the sub-pixel P10.
A touch line TP is disposed between the first subpixel P10 and the first data line D1.
The first subpixel P11 includes a first thin film transistor T1, the first thin film transistor T1 includes a first active portion 11, and since a touch line TP is disposed between the first subpixel P11 and the first data line D1, the first active portion 11 and the touch line TP are partially overlapped in a direction perpendicular to a plane where the array substrate is located.
The second sub-pixel P12 includes a second thin film transistor T2, the second thin film transistor T2 includes a second active portion 12, and since the touch line TP is not disposed between the second sub-pixel P12 and the second data line D2, the second active portion 12 does not overlap with the touch line TP in a direction perpendicular to a plane in which the array substrate is disposed.
Since the first active portion 11 of the first tft T1 needs to extend across the touch line TP to be electrically connected to the first sub-pixel P11, and the second active portion 12 of the second tft T2 does not need to extend across the touch line TP to be directly electrically connected to the second sub-pixel P12, the arrangement length of the first active portion 11 of the first tft T1 is longer than that of the second active portion 12 of the second tft T2. In the direction perpendicular to the plane of the array substrate, the first active portion 11 of the first thin film transistor T1 partially overlaps the touch line TP, and the second active portion 12 of the second thin film transistor T2 does not overlap the touch line TP, so that a coupling capacitor is formed between the first active portion 11 of the first thin film transistor T1 and the touch line TP. Therefore, when the first subpixel P11 and the second subpixel P12 have the same structure, the light-emitting luminance of the first subpixel P11 electrically connected to the first active portion 11 in the first tft T1 is lower than the light-emitting luminance of the second subpixel P12 electrically connected to the second active portion 12 in the second tft T2, that is, there is a difference between the light-emitting luminance of the first subpixel P11 electrically connected to the first active portion 11 in the first tft T1 and the light-emitting luminance of the second subpixel P12 electrically connected to the second active portion 12 in the second tft T2, which affects the display effect.
In the embodiment of the present invention, the brightness control parameter of the first sub-pixel P11 is different from the brightness control parameter of the second sub-pixel P12, so that different brightness control parameters can be selected according to the brightness difference between the first sub-pixel P11 and the second sub-pixel P12, the brightness difference between the first sub-pixel P11 and the second sub-pixel P12 is effectively improved, and the display effect is effectively improved.

In the sub-pixel row P20 adjacent to the touch line TP and located on the side of the touch line TP away from the data line D adjacent to the touch line TP, there are a first sub-pixel P11 in which the first active portion 11 and the touch line TP partially overlap in a direction perpendicular to the plane of the array substrate, and a second sub-pixel P12 in which the second active portion 12 and the touch line TP do not overlap in the direction perpendicular to the plane of the array substrate, and the first sub-pixel P11 and the second sub-pixel P12 are disposed at an interval.
Fig. 8 is a partial schematic plan view of another array substrate provided by the present invention, and referring to fig. 8, in some alternative embodiments, the array substrate includes a plurality of pixel units P, and each pixel unit P includes at least two sub-pixels P10 arranged along a first direction X.
The pixel units P arranged in the second direction Y form a pixel unit column P30, the pixel unit column P30 includes a first pixel unit column P31 and a second pixel unit column P32, and the first pixel unit column P31 and the second pixel unit column P32 are disposed at intervals.
The sub-pixels P10 arranged along the second direction Y form a sub-pixel column P20, and the array substrate includes a plurality of sub-pixel columns P20 arranged along the first direction X.
Along the first direction X, the touch lines TP located at both sides of the first pixel unit column P31 are located at a side of the data line D adjacent thereto, which is close to the first pixel unit column P31. Therefore, in the first pixel unit column P31, in the sub-pixel columns P20 located at both sides of the first pixel unit column P31 along the first direction X, there are a first sub-pixel P11 in which the first active portion 11 and the touch line TP partially overlap in a direction perpendicular to the plane of the array substrate, and a second sub-pixel P12 in which the second active portion 12 and the touch line TP do not overlap in the direction perpendicular to the plane of the array substrate, and the first sub-pixel P11 and the second sub-pixel P12 are disposed at an interval.
Along the first direction X, the touch lines TP on both sides of the second pixel unit row P32 are located on a side of the data line D adjacent thereto, which is far away from the second pixel unit row P32. Thus, in the second pixel unit column P32, there are only the second sub-pixels P12 in which the second active portion 12 does not overlap the touch line TP in a direction perpendicular to the plane of the array substrate.
Specifically, in the array substrate provided in the embodiment of the present invention, only the first subpixel P11 and the second subpixel P12 need to be disposed in the first pixel unit row P31, and the brightness control parameters of the first subpixel P11 and the second subpixel P12 are set differently, the subpixels P10 in the second pixel unit row P32 are all the second subpixels P12, and the subpixels P10 in the second pixel unit row P32 do not need to be set differently for the brightness control parameters, which is favorable for reducing the number of the pixel unit rows P30 in which the first subpixel P11 and the second subpixel P12 need to be disposed, and is favorable for improving the display effect.
With continued reference to fig. 8, in some alternative embodiments, in the first pixel unit column P31, in the same pixel unit P, two sub-pixels P10 located at two sides of the pixel unit P along the first direction X are a first sub-pixel P11 and a second sub-pixel P12, respectively, and a width of the first sub-pixel P11 along the first direction X is greater than a width of the second sub-pixel P12 along the first direction X, so as to effectively increase the light-emitting luminance of the first sub-pixel P11, and effectively improve the luminance difference between the first sub-pixel P11 and the second sub-pixel P12, thereby effectively improving the display effect.
Meanwhile, because the touch lines TP located at both sides of the first pixel unit column P31 are located at a side of the data line D adjacent to the touch lines TP and close to the first pixel unit column P31 along the first direction X, in the first pixel unit column P31, two sub-pixels P10 located at both sides of the pixel unit P along the first direction X in the same pixel unit P are respectively a first sub-pixel P11 and a second sub-pixel P12. In the two adjacent pixel units P along the second direction Y, the arrangement modes of the first sub-pixel P11 and the second sub-pixel P12 are opposite, so that when the width of the first sub-pixel P11 along the first direction X is greater than the width of the second sub-pixel P12 along the first direction X, the widths of the pixel units P in the first direction X in the first pixel unit row P31 tend to be the same, which is beneficial to the arrangement of the sub-pixels P10 in the array substrate.
In some alternative embodiments, please refer to fig. 9, where fig. 9 is a schematic plan view of a display device provided in the present invention, and a display device 1000 provided in the present embodiment includes the array substrate 100 provided in the above embodiments of the present invention. The embodiment of fig. 9 only uses a mobile phone as an example to describe the display device 1000, and it should be understood that the display device 1000 provided in the embodiment of the present invention may also be other display devices 1000 having a display function, such as a computer, a television, a vehicle-mounted display device, and the present invention is not limited thereto. The display device 1000 provided in the embodiment of the present invention has the beneficial effects of the array substrate 100 provided in the embodiment of the present invention, and specific reference may be made to the specific description of the array substrate 100 in the foregoing embodiments, which is not repeated herein.
According to the embodiment, the array substrate and the display device provided by the invention at least realize the following beneficial effects:
the array substrate provided by the invention comprises a plurality of gate lines extending along a first direction and a plurality of data lines extending along a second direction, wherein the first direction and the second direction are crossed. The gate lines and the data lines are insulatively crossed to define a plurality of sub-pixels, and the sub-pixels arranged in each column along the second direction and two data lines adjacent thereto are alternately connected in odd and even rows. When the polarities of signals transmitted on two adjacent data lines are different, the polarities of two sub-pixels adjacent to each other in the first direction may be different, and the polarities of two sub-pixels adjacent to each other in the second direction may also be different. That is to say, the array substrate provided by the invention can realize the dot inversion of the polarity of the sub-pixels in a column inversion mode, thereby reducing the flicker of pictures. The array substrate further comprises a plurality of touch lines extending along the second direction, a touch line is arranged between every two adjacent rows of sub-pixels arranged along the second direction, and the touch lines and the data lines are arranged on the same layer, so that the thickness of the array substrate is reduced. The data lines comprise a first data line and a second data line, and the first data line and the second data line are respectively positioned on two sides of the sub-pixels arranged in the same column along the second direction along the first direction. The sub-pixels comprise a first sub-pixel and a second sub-pixel, the first sub-pixel and the second sub-pixel are adjacently arranged along a second direction, the first sub-pixel is electrically connected with the first data line, and the second sub-pixel is electrically connected with the second data line. A touch control line is arranged between the first sub-pixel and the first data line. The first sub-pixel comprises a first thin film transistor, the first thin film transistor comprises a first active portion, and a touch control line is arranged between the first sub-pixel and the first data line, so that the first active portion and the touch control line are partially overlapped in the direction perpendicular to the plane where the array substrate is located. The second sub-pixel comprises a second thin film transistor, the second thin film transistor comprises a second active portion, and the second active portion is not overlapped with the touch control line along the direction perpendicular to the plane of the array substrate because no touch control line is arranged between the second sub-pixel and the second data line. The first active part in the first thin film transistor needs to extend across the touch control line to be electrically connected with the first sub-pixel, and the second active part in the second thin film transistor does not need to extend across the touch control line to be directly electrically connected with the second sub-pixel, so that the arrangement length of the first active part in the first thin film transistor is longer than that of the second active part in the second thin film transistor. In the direction perpendicular to the plane of the array substrate, the first active portion of the first thin film transistor is partially overlapped with the touch control line, and the second active portion of the second thin film transistor is not overlapped with the touch control line TP, so that a coupling capacitor is formed between the first active portion of the first thin film transistor and the touch control line. Therefore, when the first sub-pixel and the second sub-pixel have the same structure, the light-emitting brightness of the first sub-pixel electrically connected with the first active portion in the first thin film transistor is smaller than that of the second sub-pixel electrically connected with the second active portion in the second thin film transistor, that is, the light-emitting brightness of the first sub-pixel electrically connected with the first active portion in the first thin film transistor is different from that of the second sub-pixel electrically connected with the second active portion in the second thin film transistor, so that the display effect is affected. According to the invention, the brightness control parameter of the first sub-pixel is different from that of the second sub-pixel, so that different brightness control parameters can be selected according to the brightness difference of the first sub-pixel and the second sub-pixel, the brightness difference of the first sub-pixel and the second sub-pixel is effectively improved, and the display effect is effectively improved.

It will be appreciated by those skilled in the art that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
