In fig. 1, a minus sign indicates a negative polarity, and a plus sign indicates a positive polarity. In this embodiment, in the first direction, the sub-pixels in the first pixel group 10 are repeatedly arranged in a negative polarity and a positive polarity; in the second direction, the first sub-pixel group 101 in the first pixel group 10 is repeatedly arranged in a negative polarity and a positive polarity. The display panel 100 of the application realizes single-point inversion in the row direction and two-point inversion in the column direction, and can effectively solve the technical problem that the existing panel has shaking patterns.
In fig. 1, two scanning lines are disposed between two adjacent rows of sub-pixels, and the sub-pixel in any row corresponds to the two scanning lines. A first pixel group 10 includes four rows of sub-pixels, i.e. a first pixel group 10 corresponds to 8 scan lines, i.e. D1-D8.
In this embodiment, the specific connection manner between the scan line and the sub-pixels is not specifically limited, for example, as shown in fig. 1, the first, second, fifth and sixth sub-pixels in the first row of sub-pixels are connected to the second scan line G2, and the third, fourth, seventh and eighth sub-pixels in the first row of sub-pixels are connected to the first scan line G1; the connection mode of the second sub-pixel can refer to the first sub-pixel.
The second, third, sixth and seventh sub-pixels in the third row of sub-pixels are connected to a sixth scanning line G6, the fourth, fifth and eighth sub-pixels in the third row of sub-pixels are connected to the third scanning line, and the first sub-pixel in the other first pixel group 10 is connected to a fifth scanning line G5; the connection mode of the fourth sub-pixel can refer to the third sub-pixel.
For example, when M is 2, referring to fig. 2, the display panel 100 includes a first data line D1, a second data line D2, a third data line D3, a fourth data line D4, a fifth data line D5, a sixth data line D6, a seventh data line D7, and an eighth data line D8 corresponding to the first pixel group 10, and the first data line D1, the second data line D2, the third data line D3, the fourth data line D4, the fifth data line D5, the sixth data line D6, the seventh data line D7, and the eighth data line D8 are arranged in parallel. The first data line D1, the third data line D3, the fifth data line D5, and the seventh data line D7 constitute a first data line group 21, and the second data line D2, the fourth data line D4, the sixth data line D6, and the eighth data line D8 constitute a second data line group 22.
In this embodiment, the first data line D1 is electrically connected to the first subpixel group 101 in the first row, the first column, the second row, the second column, the second subpixel group 101 in the first row, the second column, the third column, the first subpixel group 101 in the first row, the third column, the fourth column, the fifth data line D5, the fifth column, the sixth column, the seventh column, the eighth column, the seventh column, the eighth column, the seventh column, and the eighth column, the eighth data line D8 is electrically connected to the first sub-pixel group 101 of the first row and eighth column, and the eighth data line D8 is electrically connected to the first sub-pixel group 101 of the second row and first column in another first pixel group 10.
If this embodiment still has the same polarity structure as that of fig. 1, that is, in the first direction, the sub-pixels in the first pixel group 10 are repeatedly arranged in the form of negative polarity and positive polarity, and single-point inversion is implemented in the row direction; in the second direction, the first sub-pixel group 101 in the first pixel group 10 is repeatedly arranged in a negative polarity and a positive polarity, and two-dot inversion is performed in the column direction.
In this embodiment, at least three scanning lines are disposed between two adjacent rows of the sub-pixels, and one row of the sub-pixels is electrically connected to the at least three scanning lines. In one of the first pixel groups 10, at least one of the scanning lines between two adjacent rows of the sub-pixels is shared by two adjacent rows of the sub-pixels.
For example, referring to fig. 2, three scan lines are disposed between two adjacent rows of the sub-pixels. A first pixel group 10 includes four rows of sub-pixels, i.e., a first pixel group 10 corresponds to 12 scan lines, i.e., G1-G12.
The scan line connection in this embodiment is substantially similar to that in fig. 1, except that:
in one first pixel group 10, the fourth scanning line, the seventh scanning line and the tenth scanning line are shared by two adjacent rows of sub-pixels, so that the number of data lines is reduced.
In another embodiment of the present application, four scan lines are disposed between two adjacent rows of sub-pixels, i.e. 16 scan lines correspond to one first pixel group 10. Compared with fig. 2, one scanning line is added to any row of sub-pixels, so that the technical problems of crosstalk of scanning signals and the like are avoided.
In the above embodiment, the distance between any sub-pixel and two adjacent data lines is equal.
Referring to fig. 3, taking any one of the sub-pixels in fig. 1 to 2 as an example, since a pixel electrode layer is disposed in the sub-pixel, a certain voltage exists on the pixel electrode layer, and a voltage also exists on the data line, a coupling voltage exists between any one data line and any one sub-pixel, D in fig. 3 is a data line, and G is a scan line. As shown in fig. 3, a coupling capacitor C1 is formed between the sub-pixel and the left data line, and a coupling capacitor C2 is formed between the sub-pixel and the right data line. Since the input voltages of any one data line are equal, the C1 and the C2 of the present application are equal, and the technical problem of vertical crosstalk of the panel is avoided.
In this embodiment, the sub-pixel and the data line may have a pitch of 5 μm.
Along with the gradual increase of the size of the panel, the data lines and the scanning lines are longer and longer, the signal transmission speed is influenced by the length of the conducting wires, so that the impedance far away from the data transmission end is larger and larger, the received voltage is gradually reduced, and the received signals are delayed to a certain degree; in addition, the coupling capacitance between the sub-pixel and two adjacent data lines is smaller and smaller, so that the panel is abnormal.
Referring to fig. 4, on the basis of fig. 3, it is assumed that the second direction of the present application is a transmission direction of the data signal. In the second direction, the distance between the sub-pixel far away from the data transmission end and two adjacent data lines is gradually reduced. In this embodiment, the distance between the sub-pixel and the two adjacent data lines is reduced, so that the coupling capacitance between the sub-pixel and the data line is increased, and the coupling capacitance between any sub-pixel and the data line is ensured to be equal, for example, the distance L1 in fig. 4 is greater than the distance L2.
In fig. 1 to 2, the first data line group 21 includes a first connection line 210 connecting a plurality of data lines in the first data line group in parallel, the second data line group 22 includes a second connection line 220 connecting a plurality of data lines in the second data line group in parallel, the first connection line 210 includes a first metal bridge 211 overlapping with the second data line group 22, that is, the first connection line 210 crosses over the second data line group 22 through the first metal bridge 211, and the second connection line 220 includes a second metal bridge 221 overlapping with the first data line group 21, that is, the second connection line 220 crosses over the first data line group 21 through the second metal bridge 221.
In this embodiment, the first metal bridge 211 or/and the second metal bridge 221 is formed by a metal layer of a non-source drain layer in the display panel 100.
Please refer to fig. 5, which is a cross-sectional view of a metal bridge. Two adjacent data lines are arranged through a cross line, so that the data lines in the same data line group are arranged in parallel. For example, the first connection line 210 includes a first connection section 212 formed of a first metal layer and a first metal bridge 211 formed of a second metal layer, the first metal bridge 211 is located between the first connection sections 212, and the first metal bridge 211 is electrically connected to the first connection sections 212 through vias. The first metal layer and the second metal layer are arranged in different layers.
