X1 of the gate drive circuits  300  provide a plurality of stages of scanning signals to each of the main pixel drive circuits  200 . Therefore, the scanning signals of the auxiliary pixel drive circuit  100  and the main pixel drive circuit  200  corresponding to the auxiliary sub-pixel  102  and the main sub-pixel  202  arranged on a same composite pixel row  101  are different. The problem of the display mismatch between the main display area  100   b  and the functional additional area  100   a  is improved. 
     Furthermore, X1≥2, and X2≥3. That is, at least three of the gate drive circuits  300  provide a plurality of stages of scanning signals to each of the auxiliary pixel drive circuits  200 . At least two of the gate drive circuits  300  provide a plurality of stages of scanning signals to each of the main pixel drive circuits  200 . Therefore, a number of the scanning signals used by each of the auxiliary pixel drive circuits  100  is different from a number of the scanning signals used by the main pixel drive circuit  200  corresponding to each of the main sub-pixels  202  in a same composite pixel row  101  as the plurality of auxiliary sub-pixels  102  connected to the auxiliary pixel drive circuit  100 . 
     Furthermore, the number of the scanning signals used by each of the auxiliary pixel drive circuits  100  is greater than the number of the scanning signals used by the main pixel drive circuit  200  corresponding to each of the main sub-pixels  202  in a same composite pixel row  101  as the plurality of auxiliary sub-pixels  102  connected to the auxiliary pixel drive circuit  100 . Specifically, the number of the scanning signals used by each of the auxiliary pixel drive circuits  100  is x2. The number of the scanning signals used by the main pixel drive circuit  200  corresponding to each of the main sub-pixels  202  in a same composite pixel row  101  as the plurality of auxiliary sub-pixels  102  connected to the auxiliary pixel drive circuit  100  is x1, where x1&lt;x2. Furthermore, x1≥2, and x2≥3. 
     Alternatively, each of the auxiliary pixel drive circuits  100  and X2 of the gate drive circuits  300  are connected by X22 of the scanning signal lines to transmit x2 of the scanning signals to the auxiliary pixel drive circuits  100 . Each of the main pixel drive circuits  200  and X1 of the gate drive circuits  300  are connected by X11 of the scanning signal lines to transmit x1 of the scanning signal to the main pixel drive circuits  200 . X11 can be equal to or different from X22. Furthermore, X11=X22=3. 
     According to different positions of the main pixel rows  201  and the composite pixel rows  101 , the gate drive circuits  300  correspondingly provide different scanning signals to the plurality of main pixel drive circuits  200  which drive the plurality of main sub-pixels  202  disposed in the main pixel rows  201  to emit light, the main pixel drive circuit  200  which drives the plurality of main sub-pixels  202  disposed in the composite pixel rows  101  to emit light, and the auxiliary pixel drive circuit  100  which drives the plurality of auxiliary sub-pixels  102  disposed in the composite pixel rows  101  to emit light. Thus, for the convenience of description, a working principle of the display panel is explained by taking the plurality of composite pixel rows  101  arranged behind a M-th main pixel row of the plurality of main pixel rows  201  as an example. That is, a first pixel row to the M-th pixel row are the main pixel rows  201 , and a (M+1)th pixel row is a first composite pixel row. The plurality of composite pixel rows  101  are arranged behind a last main pixel row of the plurality of main pixel rows  201 .

The second compensation module is configured to transmit the second data signal Data2 to the gate of the main drive transistor Tmd according to the third stage scanning signal (i.e., the seventh stage scanning signal Scan(7)) to compensate the threshold voltage of the main drive transistor Tmd. 
     That is, the scanning signals used by the auxiliary pixel drive circuit connected to the plurality of auxiliary sub-pixels  102  disposed in the first composite pixel row  1011  to the third composite pixel row  1013  (i.e., p=1, q=3) are the scanning signals Scan(4), Scan(5), and Scan(7), or the scanning signals Scan(4), Scan(6), and Scan(7). The scanning signals used by the main pixel drive circuit connected to one main sub-pixel  102  disposed in the first composite pixel row  1011  are the scanning signals Scan(4) and Scan(5). The scanning signals used by the main pixel drive circuit connected to one main sub-pixel  102  disposed in the second composite pixel row  1012  are the scanning signals Scan(5) and Scan(6). The scanning signals used by the main pixel drive circuit connected to one main sub-pixel  102  disposed in the third composite pixel row  1013  are the scanning signals Scan(6) and Scan(7). 
     Similarly, it is also possible to obtain not only the embodiment in the first composite pixel row  1011  to the third composite pixel row  1013 , but also an embodiment in which one of the plurality of auxiliary pixel drive circuits  100  is connected to the plurality of auxiliary sub-pixels  102  disposed in three of the composite pixel rows  101  (i.e., q−p+1=3), which will not be repeated here.
