It should be understood that, instead of parasitic capacitance on the Scan lines 4, as the size of the display panel increases, the number of pixels 3 carried on one Scan (Scan) line also increases, and the Scan line also increases, the larger the RC, especially the larger the difference between the RC at the leftmost end and the RC at the rightmost end, as shown in fig. 2, the larger the difference between the waveform of the Scan at the leftmost end and the waveform at the rightmost end, the more serious the resistance-capacitance delay (RC delay), especially the non-uniformity of C, the more non-uniform the left and right display of the pixel row 1 connected by the scan line 4, which finally results in the display quality being reduced while the size of the display panel is increased, affecting the user experience, the display panel provided by the application divides the pixel row into at least two sub-display areas, and controls the sub-display areas through the corresponding scanning lines, so that the RC value of each scanning line is reduced, and the waveform difference of the left end and the right end of the same pixel row is further reduced.
It should be understood that the number of sub display regions 2 in one pixel row 1 is not limited, for example, each pixel row 1 may include two sub display regions 2, and each pixel row 1 may further include three or four sub display regions 2; it should be noted that in some examples, in the same display panel, the sub-display regions 2 of all the pixel rows 1 are the same, that is, the number of the sub-display regions 2 of all the pixel rows 1 in the display panel is the same, and the positions of the sub-display regions 2 of all the pixel rows 1 are the same; for example, as shown in fig. 3, each pixel row 1 of the display panel includes two sub-display regions 2 therein, and the sub-display regions 2 of all the pixel rows 1 are the same.
