Fig. 1 is a schematic structural diagram of a display panel in the prior art, as shown in fig. 1, in the prior art, for a special-shaped display panel, since shapes of display areas are diversified, in order to match shapes of different display areas, data lines 10 with different lengths are connected to different sub-pixels 11, so that a difference between lengths and capacitances of a plurality of data lines 10 in the special-shaped display panel is large, and further RC loading between different data lines 10 is different, resulting in an obvious charging difference, especially in a low gray scale display stage, a display luminance corresponding to a short display area of the data line 10 is easily low, and further, a display uniformity of the display panel is seriously affected.
To solve the above technical problem, an embodiment of the present invention provides a display panel, including: the display area comprises a plurality of data lines, and the number of sub-pixels of two data lines which are electrically connected is different; the display panel also comprises a plurality of capacitance compensation structures, and the capacitance values of the capacitance compensation structures corresponding to the data lines with different numbers of the connected sub-pixels are different.

The display panel 100 includes a special-shaped display panel, the lengths of the data lines 102 in different display areas 101 in the special-shaped display panel are different, and then the number of sub-pixels electrically connected to the data lines 102 with different lengths is also different, and the capacitance difference between different data lines 102 is large, so that by providing the capacitance compensation structure 103 on the display panel 100, the capacitance compensation structures 103 with different capacitance values are provided on the data lines 102 corresponding to different sub-pixel numbers, and then the capacitance difference between different data lines 102 is compensated, and the capacitance difference between the data lines 102 with different sub-pixel numbers is reduced, thereby ensuring a normal display effect. The capacitance compensation structure 103 may be an additionally disposed capacitance structure, or because the capacitance Cdata on the data line 102 satisfies the formula Cdata = Cdc + Cgd + Cpd, where Cdc is a capacitance between the data line 102 and the common electrode 104, cgd is a capacitance between the data line 102 and the scan line, and Cpd is a capacitance between the data line 102 and the pixel electrode 107, and it can be seen that the capacitance on the data line 102 is related to the data line 102, the scan line, the common electrode 104, and the pixel electrode 107 in the display panel 100, so that the structures of the data line 102, the common electrode 104, the scan line 108, the pixel electrode 107, and the like in the display panel 100 can be multiplexed, and the capacitive coupling between the signal lines is increased or reduced, thereby increasing or reducing the capacitance difference between different signal lines to ensure the display effect. Illustratively, as shown in fig. 2, the capacitance compensation structure 103 is composed of the data lines 102 and the common electrode 104, and by adjusting the overlapping areas between different data lines 102 and the common electrode 104, the coupling capacitance between the data lines 102 and the common electrode 104 is affected, the overlapping area between the data line 1021 with a larger number of connected sub-pixels and the common electrode 104 is smaller than the overlapping area between the data line 1022 with a smaller number of connected sub-pixels and the common electrode 104, and the coupling capacitance between the data line 1021 with a larger number of connected sub-pixels and the common electrode 104 is smaller than the coupling capacitance between the data line 1022 with a smaller number of connected sub-pixels and the common electrode 104, so as to appropriately reduce the capacitance difference between the data line 1021 with a larger number of connected sub-pixels and the data line 1022 with a smaller number of connected sub-pixels, and ensure the display effect of the display panel 100. The specific type of the capacitance compensation structure 103 may be selected according to actual design requirements, and the embodiment of the present invention is not particularly limited. Simultaneously to other rete structures of data line one side among the display panel, for example, the design of black matrix can keep original design, guarantees the aperture opening ratio, and then guarantees display panel's light-emitting effect.
