In the embodiment of the present invention, as shown in fig. 2, fig. 2 is a schematic structural diagram of a plurality of sub-pixel regions in a display panel according to an embodiment of the present invention, where the plurality of sub-pixel regions at least include a first sub-pixel region a1, the first sub-pixel region a1 includes a first opening region a11 and a first TFT device region a12 which are sequentially arranged in a first direction Y, and an area of the first opening region a11 is smaller than an area of opening regions of other adjacent sub-pixel regions.
The data lines at least include a first data line D1 and a second data line D2, and the first data line D1 or the second data line D2 is electrically connected to the TFT devices of the first TFT device region a12, that is, the first data line D1 or the second data line D2 is electrically connected to the sources of the thin film transistors of the first TFT device region a12, so as to provide data signals to the first sub-pixel region a 1.
The first data line D1 is located at a first side of the first sub-pixel region a1, the second data line D2 is located at a second side of the first sub-pixel region a1, the first side and the second side are opposite sides of the first sub-pixel region a1 in a second direction X, and the second direction Y is perpendicular to the first direction X.
The first data line D1 at least comprises a first bending part, the first bending part comprises a first sub-line D11, a second sub-line D12 and a first inflection point D13, the first sub-line D11 and the second sub-line D12 are sequentially arranged in the first direction Y, and the first inflection point D13 is connected with the first sub-line D11 and the second sub-line D12. The second data line D2 at least comprises a second bending part, the second bending part comprises a third sub-line D21, a fourth sub-line D22 and a second inflection point D23, the third sub-line D21 and the fourth sub-line D22 are sequentially arranged in the first direction Y, and the second inflection point D23 is connected with the third sub-line D21 and the fourth sub-line D22.
Here, the first inflection point D13 and the second inflection point D23 are disposed near the boundary line S1 between the first opening region a11 and the first TFT device region a12, or, the first inflection point D13 is an inflection point on the first data line D1 that is closest to the boundary line S1 between the first opening region a11 and the first TFT device region a12, and the second inflection point D23 is an inflection point on the second data line D2 that is closest to the boundary line S1 between the first opening region a11 and the first TFT device region a 12. That is, the vertical distance from the first inflection point D13 to the boundary S1 between the first opening region A11 and the first TFT device region A12 is smaller than the vertical distance from the first inflection point D13 to the boundary S2 between the first opening region A11 and another TFT device region A22 adjacent thereto; the vertical distance from the second inflection point D23 to the boundary S1 between the first opening area A11 and the first TFT device area A12 is smaller than the vertical distance from the second inflection point D23 to the boundary S2 between the first opening area A11 and another TFT device area A22 adjacent thereto.
In the drawings of the embodiments of the present invention, a dot is provided at the inflection point in order to highlight the position of the inflection point, but in practical applications, the dot is not provided at the inflection point, that is, the line width at the inflection point is equal to or approximately equal to the line width in other regions.
Since the area of the first opening region a11 is smaller than the area of the opening regions of the adjacent other sub-pixel regions, that is, the area of the first sub-pixel region a1 is smaller than the area of the adjacent other sub-pixel regions, if the first data line D1 and the second data line D2 are both bent at the line S3 near the intersection line S1 of the first opening region a11 and the first TFT device region a12, that is, the first inflection point is located at the line S3 as shown by the dotted line, the area of the first TFT device region a12 is smaller than the area of the TFT device regions of the adjacent other sub-pixel regions, and the smaller area of the first TFT device region a12 results in a smaller range in which the size or the size accuracy of the TFT devices in the first TFT device region a12 can fluctuate, thereby resulting in a greater difficulty in manufacturing the TFT devices in the first TFT device region a 12.
Based on this, in order to increase the area of the first TFT device region a12, in some embodiments of the present invention, the first inflection point D13 is located at a first side of the first opening region a11, and the second inflection point D23 is located at a second side of the first TFT device region a 12.

Alternatively, in another alternative embodiment, as shown in fig. 3, fig. 3 is a schematic structural diagram of a plurality of sub-pixel regions in a display panel according to another embodiment of the present invention, the first inflection point D13 may be moved in a direction away from the first TFT device region a12 in the first direction Y, and the second inflection point D23 may be moved in the direction away from the first opening region a11 in the first direction Y, that is, a vertical distance from the second inflection point D23 to a boundary S1 between the first opening region a11 and the first TFT device region a12 is greater than a vertical distance from the line S3 to a boundary S1 between the first opening region a11 and the first TFT device region a 12.
As shown in fig. 2, after the first inflection point D13 moves in the first direction Y away from the first TFT device area a12, the extending direction of the second sub-line D12 is kept unchanged, the second sub-line D12 moves to the left by a certain distance L1, that is, the second sub-line D12 moves in the second direction X away from the first TFT device area a12 by a certain distance L1, so that the area of the first TFT device area a12 can be increased under the condition that the area of the first opening area a11 is basically unchanged, the size or the fluctuation range of the size precision of the TFT devices in the first TFT device area a12 can be increased, and the difficulty in manufacturing the TFT devices in the first TFT device area a12 can be reduced.
As shown in fig. 3, on the basis that the first inflection point D13 is moved in the first direction Y away from the first TFT device area a12 to increase the area of the first TFT device area a12, the second inflection point D23 is moved in the first direction Y away from the first opening area a11, that is, the second inflection point D23 is moved downward, and then the extending direction of the fourth sub-line D22 is kept unchanged, the fourth sub-line D22 is moved rightward by a distance L4, that is, the fourth sub-line D22 is moved by a distance L4 in the second direction X away from the first TFT device area a12, so that the area of the first TFT device area a12 can be further increased, the range of fluctuation in size or size precision of the TFT devices in the first TFT device area a12 can be further increased, and the difficulty in manufacturing the TFT device area a12 can be further reduced.
Of course, the present invention is not limited thereto, and in other embodiments, in order to increase the area of the first TFT device area a12, as shown in fig. 4, fig. 4 is a schematic diagram of a structure of a plurality of sub-pixel regions in a display panel according to another embodiment of the present invention, the first inflection point D13 is located on a first side of the first TFT device area a12, the second inflection point D23 is located on a second side of the first TFT device area a12, and, in the first direction Y, a vertical distance L3 from the second inflection point D23 to the first opening area a11 is greater than a vertical distance L2 from the first inflection point D13 to the first opening area a11, or, in the first direction Y, a vertical distance L3 from the second inflection point D23 to an intersection between the first opening area a11 and the first TFT device area a 12S 573s 5 is greater than a vertical distance L2 from the first inflection point D13 to an intersection between the first opening area a11 and the first TFT device area a 12S 1.
That is, as shown in fig. 4, the position of the first inflection point D13 is kept constant, and is still at the line S3 as the inflection points of other data lines, the second inflection point D23 is moved in the first direction Y in a direction away from the first opening area a11, and the extending direction of the fourth sub-line D22 is kept constant by moving the second inflection point D23 downward, so that the fourth sub-line D22 is moved rightward by a distance L4, that is, the fourth sub-line D22 is moved by a distance L4 in the second direction X in a direction away from the first TFT device area a12, so that the area of the first TFT device area a12 can be increased while the area of the first opening area a11 is kept substantially constant.
It should be noted that, in some embodiments of the present invention, the TFT device of the first TFT device area a12 includes a thin film transistor, and a source of the thin film transistor is connected to the second sub-line D12; alternatively, the source of the thin film transistor is connected to the fourth sub-line D22. After the area of the first TFT device area a12 is increased, the area of the thin film transistor can be increased, for example, the size of the drain metal block or the fluctuation range of the size precision can be increased, so as to reduce the difficulty of manufacturing the thin film transistor.
It should be further noted that, in some embodiments of the present invention, after the first inflection point D13 is shifted, the extending directions of the first sub-line D11 and the third sub-line D21 are kept unchanged, that is, the first sub-line D11 and the third sub-line D21 extend in the same direction as other data lines sequentially arranged in the second direction X, or the first sub-line D11 and the third sub-line D21 are parallel to other data lines sequentially arranged in the second direction X.
Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the area of the first opening region a11 may be fine-tuned by fine-tuning the extending direction of the first sub-line D11 and/or fine-tuning the extending direction of the third sub-line D21, so as to ensure that the ratio of the opening regions of the first opening region a11 and the other sub-pixel regions is constant, so that the optical effect of the first sub-pixel region a1 is constant, or the ratio of the opening regions of the first opening region a11 and the other sub-pixel regions is a predetermined ratio, so that the optical effect of the first sub-pixel region a1 is a predetermined effect.
It should be noted that when the area of the opening region is adjusted by fine-tuning the first sub-line D11 and/or the third sub-line D21, the area of the first opening region a12 can be ensured to be unchanged by ensuring the second sub-line D12 and/or the fourth sub-line D22 to be unchanged, that is, in the embodiment of the present invention, the area of the opening region can be adjusted only by adjusting the first sub-line D11 and/or the third sub-line D21 while ensuring the area of the first opening region a12 to be unchanged.
