Width on second direction x；First display area, 111 corresponding scan line is multiplexing scan line 211, the second display area
112 corresponding scan lines are multiplex scan line 212.
Specifically, in order to adapt to more application scenarios, in addition to the display panel of rectangular display area, abnormity is had also appeared
Display panel, i.e. display area have irregular shape, such as display panel shown in Fig. 4, the top sides of display area 11
Edge is arc-shaped structure, and the corresponding region of arc-shaped structure is the first display area 111,111 lower section of the first display area
Region is rectangular display area, i.e. the second display area 112, in the first display area 111, on direction from top to bottom, the
Width of one display area 111 on second direction x gradually increases, but respectively less than the second display area 112 is in second direction x

Width, i.e. arbitrary a line is less than the second viewing area for realizing the quantity of the sub-pixel of display function in the first display area 111
Arbitrary a line is for realizing the quantity of the sub-pixel of display function in domain 112, and therefore, every scans in the first display area 111
The quantity for the display thin film transistor (TFT) that line is connected is less than the display film that every scan line is connected in the second display area 112
The quantity of transistor, therefore, if scan line is not connected to pressure sensitive sensor, the scan line in the first display area is born
The load for being less than scan line in the second display area is carried, the charging effect and second of the first display area sub-pixel can be made in this way
The charging effect of display area sub-pixel is variant, so as to cause under identical data-signal, the son of the first display area

Make, multiplex scan line 212 is only used for the charging of driving sub-pixel.The charging required time of sub-pixel is shorter, and pressure
The 3 required time of inductive pick-up is longer, therefore, in order to ensure pressure sensitive sensor 3 can work normally, setting multiplexing
The conduction level duration in scan line 211 is more than the conduction level duration in multiplex scan line 212, in this way, right
During sub-pixel in first display area 111 is scanned, make illusory thin film transistor (TFT) that there is longer turn-on time,
To ensure that pressure sensitive sensor 3 can work normally, and to process that the sub-pixel of the second display area 112 is scanned

Optionally, the conduction level duration in every multiplexing scan line 211 is X1,4.3 μ of μ s≤X1≤100 s；Often
The conduction level duration in multiplex scan line 212 is X2,4.3 μ of μ s≤X2≤12.9 s.
Specifically, display panel is usually provided with 1920 row sub-pixels at present, and higher refreshing frequency is 120Hz, i.e., often
Second refresh 120 times, the charging time of average often row sub-pixel is 4.3 μ s, and lower refreshing frequency is 30Hz, i.e. each second brushes
New 30 times, the charging time of average often row sub-pixel is 12.9 μ s, therefore, for be only used for driving sub-pixel charge it is non-
It being multiplexed for scan line 212, the conduction level duration is 4.3 μ s between 12.9 μ s, and for being multiplexed scan line 211,
Its conduction level duration needs the conduction level duration more than multiplex scan line 212, therefore, 4.3 μ s of setting≤
X1, on the other hand, for current pressure sensitive sensor 3, the driving time of 100 μ s is enough to make pressure sensitive sensor
3 can work normally, therefore, the setting μ of X1≤100 s.
Optionally, the first display area 111 includes the multirow sub-pixel along first direction y arrangements；Second display area 112
