The mth first data line may be an data line in the mth column and the mth second data line may be an data line in the (m+1)th column, or the mth first data line may be the data line in the (m+1)th column and the mth second data line may be the data line in the mth column, where m and n are both positive integers.
During the implementation, each subpixel circuit may include a subpixel and a switching element, and the switching element may be, but not limited to, a switching transistor.
In the embodiments of the present disclosure, the subpixel in the (2n−1)th row and the mth column may be electrically connected to the mth first data line through the switching element in the (2n−1)th row and the mth column, and the subpixel circuit in the (2n)th row and the mth column may be electrically connected to the mth second data line through the switching element in the (2n)th row and the mth column, i.e., for the subpixel circuits in a same column, the subpixel circuits in odd-numbered rows may be electrically connected to a data line different from the subpixel circuits in even-numbered rows to form a Z-like structure.

The gate driving circuit is configured to, at an nth display stage, control the gate line in the (2n−1)th row and the gate line in the (2n)th row to output the effective gate driving signals simultaneously to turn on the switching elements whose control electrodes are electrically connected to the gate line in the (2n−1)th row and the switching elements whose control electrodes are electrically connected to the gate line in the (2n)th row. The data driving circuit is configured to, at the nth display stage, provide corresponding nth data voltages to the data lines to charge the corresponding subpixels.
As shown in
The data driving circuit is electrically connected to a data line D1 in the first column, a data line D2 in the second column, a data line D3 in the third column and a data line D4 in the fourth column, and configured to, at the nth display stage, provide the corresponding nth data voltages to the data lines to charge the corresponding subpixels, and at the (n+1)th display stage, provide corresponding (n+1)th data voltages to the data lines to charge the corresponding subpixels.
In the embodiments of the present disclosure, the display period may further include a pre-charging stage between adjacent display stages, and a pre-charging stage between an nth display stage and an (n+1)th display stage may be an nth pre-charging stage. The gate driving circuit is configured to, at the nth pre-charging stage, control the gate line in the (2n−1)th row, the gate line in the (2n)th row, the gate line in the (2n+1)th row and the gate line in the (2n+2)th row to provide the effective gate driving signals to turn on the switching elements whose control electrodes are electrically connected to the gate line in the (2n−1)th row, the switching elements whose control electrodes are electrically connected to the gate line in the (2n)th row, the switching elements whose control electrodes are electrically connected to the gate line in the (2n+1)th row and the switching elements whose control electrodes are electrically connected to the gate line in the (2n+2)th row. The data driving circuit is configured to, at the nth pre-charging stage, provide the corresponding nth data voltages to the data lines so as to charge the corresponding subpixels.
