Display panel and display drive method thereof, and display device

A display panel, comprising a plurality of display regions, a plurality of scan drive circuits, and a controller, wherein the plurality of display regions comprise a first display region and a second display region that are parallel to each other and do not overlap with each other, the plurality of scan drive circuits comprise a first scan drive circuit and a second scan drive circuit;

• wherein,
• the controller is electrically connected to the first scan drive circuit and the second scan drive circuit to control the first scan drive circuit and the second scan drive circuit to output a first light-emitting control signal and a second light-emitting control signal, respectively;
• the first display region is electrically connected to the first scan drive circuit to receive the first light-emitting control signal;
• the second display region is electrically connected to the second scan drive circuit to receive the second light-emitting control signal;
• and
• the controller is configured to individually adjust a pulse width of at least one of the first light-emitting control signal and the second light-emitting control signal to adjust a light-emitting duration of light-emitting elements of the first display region and a light-emitting duration of light-emitting elements of the second display region within one display period, respectively, based on a light-emitting brightness balance point of the light-emitting elements of the first display region or a light-emitting brightness balance point of the light-emitting elements of the second display region,
• wherein the display panel is a foldable display panel and comprises a folding axis, the first display region and the second display region are divided along the folding axis,
• wherein the light-emitting brightness balance point of the light-emitting elements of the first display region is an intersection of a first curve and a second curve, the first curve indicating the relationship between the usage duration of light-emitting elements of the first display region and the brightness of light-emitting elements of the first display region, the second curve indicating the relationship between brightness of light-emitting elements of the first display region and the pulse width of the first light-emitting control signal, or
• the light-emitting brightness balance point of the light-emitting elements of the second display region is an intersection of a third curve and a fourth curve, the third curve indicating the relationship between the usage duration of light-emitting elements of the second display region and the brightness of light-emitting elements of the second display region, the fourth curve indicating the relationship between brightness of light-emitting elements of the second display region and the pulse width of the second light-emitting control signal.
