N is a natural number of 2 or more.
Each column of sub-pixel units 1 comprises a plurality of first sub-pixel units, a plurality of second sub-pixel units and a plurality of third sub-pixel units which are arranged along a first direction; each of the first sub-pixel unit, the second sub-pixel unit and the third sub-pixel unit comprises a light emitting device, and an anode of each light emitting device is arranged on the same layer.
Alternatively, the Light Emitting device may be a Light Emitting Diode (LED) or an Organic Light Emitting Diode (OLED), in which case the display panel is an organic Light Emitting display panel, and the application does not limit the type of the Light Emitting device.
The first direction is the same as the extending direction of the data lines in each data line group, and the first direction may also be referred to as a column direction, a y direction, a longitudinal direction, or the like.
Each sub-pixel unit includes a pixel circuit that corresponds one-to-one to the light emitting devices (including the anodes of the light emitting devices) in the corresponding sub-pixel unit, and this one-to-one correspondence is indicated by a dashed arrow in fig. 1.
Optionally, one or both of the first sub-pixel unit, the second sub-pixel unit and the third sub-pixel unit in the same column of sub-pixel units belong to different pixel units from other sub-pixel units. Such as: referring to fig. 1, for the 2i-1 th column of sub-pixel units, the first sub-pixel unit 11 and the second sub-pixel unit 12 belong to the same pixel unit 14, which is different from the pixel unit 15 to which the third sub-pixel unit 13 belongs. i is a natural number not less than 1, and 2i +1 is not more than N.
Of course, each sub-pixel unit 1 may further include other components, and the present embodiment does not list the components included in the sub-pixel unit 1.
The first data line group comprises a plurality of first data lines 2, and each first data line 2 corresponds to one odd column of sub-pixel units (for example, the 2i-1 column of sub-pixel units in fig. 1), is connected with the first sub-pixel unit and the second sub-pixel unit in the corresponding odd column of sub-pixel units, and is used for providing a first data signal.
The second data line group comprises a plurality of second data lines 3, and each second data line 3 corresponds to two adjacent columns of sub-pixel units (for example, the 2i-1 th column and the 2i th column of sub-pixel units in fig. 1) and is connected with a third sub-pixel unit in the corresponding two adjacent columns of sub-pixel units for providing a second data signal.
The third data line group comprises a plurality of third data lines 4, and each third data line 4 corresponds to one column of even-numbered sub-pixel units (for example, the 2 i-th column of sub-pixel units in fig. 1), is connected with the first sub-pixel unit and the second sub-pixel unit in the corresponding even-numbered column of sub-pixel units, and is used for providing a first data signal.
The data line groups (including the first data line group, the second data line group and the third data line group) extend along the longitudinal direction and are parallel to each other.
The first data line group, the second data line group and the third data line group are respectively arranged with the anode different layers of the light-emitting device. Typically, a dielectric layer is present between each data line group and the layer on which the anode is located, which dielectric layer may cause parasitic capacitance to be generated between the data line group and the layer on which the anode is located. At this time, in a direction perpendicular to the display panel, the parasitic capacitance corresponding to the data line shielded by the anode is larger than the parasitic capacitance corresponding to the data line not shielded by the anode. Such as: referring to fig. 2, for the first data line 2 corresponding to the sub-pixel unit of the 2i-1 th column, the first data line 2 is shielded by the anode 21 in the sub-pixel unit of the 2i-1 th column; for the second data line 3 corresponding to the sub-pixel unit in the 2i-1 th column and the sub-pixel unit in the 2i-1 th column, the second data line 3 is shielded by the anode 22 in the sub-pixel unit in the 2i-1 th column; for the third data line 4 corresponding to the sub-pixel unit in the 2 i-th column, the third data line 4 is not shielded by the anode 23. In this pixel arrangement, the parasitic capacitance between the first data line 2 and the anode is greater than the parasitic capacitance between the third data line 4 and the anode, resulting in a greater load on the first data line 2 than on the third data line 4. Thus, the data refresh frequency of the first data line 2 is lower than the data refresh frequency of the third data line 4, and when the data refresh frequency is higher, the sub-pixel units in a row connected to the first data line 2 and the sub-pixel units in a row connected to the third data line 4 are spaced from each other and are bright. Wherein i is a natural number of 1 or more.
In view of the above technical problem, the present application provides a display panel, wherein a projected overlapping area of any one of the first data lines 2 in the first data line group and an anode of the light emitting device in a direction perpendicular to the display panel is the same as a projected overlapping area of any one of the third data lines 4 in the third data line group and an anode of the light emitting device in a direction perpendicular to the display panel.
In the present application, the projection overlapping area of the first data line 2 and the anode of the light emitting device in the direction perpendicular to the display panel is the same as the projection overlapping area of the third data line 4 and the anode of the light emitting device in the direction perpendicular to the display panel, including the following two cases: first, a projection overlapping area of the first data line and the anode of the light emitting device in a direction perpendicular to the display panel is greater than 0; the projection overlapping area of the third data line and the anode of the light-emitting device in the direction perpendicular to the display panel is greater than 0; and the second method comprises the following steps: the projected overlapping area of the first data line and the anode of the light emitting device in the direction perpendicular to the display panel is equal to 0; the projected overlapping area of the third data line and the anode of the light emitting device in the direction perpendicular to the display panel is equal to 0. The display panels for the above two cases will be described below.

In fig. 3, each data line group is illustrated as being located below the layer where the anode is located in a direction perpendicular to the display panel, in practical implementation, each data line group may also be located above the layer where the anode is located, and the stacking order between the layer where each data line group is located and the layer where the anode is located is not limited in this embodiment.
For the second kind of display panel, in one example, referring to fig. 4, the projection of the first data line 2 corresponding to the 2i +1 th column of sub-pixel units and the third data line 4 corresponding to the 2i th column of sub-pixel units in the direction perpendicular to the display panel is located between the anode of the 2i +1 th column of sub-pixel units and the projection of the anode of the 2i th column of sub-pixel units in the direction perpendicular to the display panel; the first data line 2 corresponding to the sub-pixel unit of the 2i-1 th column does not overlap with the projection of the anode of the sub-pixel unit of any column in the direction vertical to the display panel; the third data line 4 corresponding to the sub-pixel unit in the 2 i-th column overlaps with the projection of the anode of the sub-pixel unit in the 2i + 1-th column in the direction perpendicular to the display panel; a second data line 3 corresponding to the sub-pixel units in the 2i-1 th column and the 2i th column overlaps with the projection of the anode of the sub-pixel unit in the 2i th column in the direction vertical to the display panel; wherein i is a natural number not less than 1, and 2i +1 is not more than N.

Alternatively, the projections of the pixel circuits in the second data line 3 and the 2i-1 column sub-pixel unit corresponding to the 2i-1 column sub-pixel unit and the 2i-1 column sub-pixel unit in the direction perpendicular to the display panel constitute a first arrangement shape.
