Title:
DISPLAY PANEL, DISPLAY DEVICE AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/000235
Kind Code:
A1
Abstract:
A display panel, a display device, and a driving method. The display panel comprises a plurality of display regions, and the plurality of display regions comprise a first display region and a second display region that are parallel to one another and do not overlapped. The first display region comprises a plurality of rows of first pixel units arranged in an array, and the second display region comprises a plurality of rows of second pixel units arranged in an array. The display panel further comprises a first light-emitting control scan driving circuit used for controlling the plurality of rows of first pixel units to emit light, and a second light-emitting control scan driving circuit used for controlling the plurality of rows of second pixel units to emit light. The driving method comprises: enabling each image frame of the first display region to comprise a first sub-frame and a second sub-frame that do not overlap with each other; in the first sub-frame, providing a first start signal to the first light-emitting control scan driving circuit so that the plurality of rows of first pixel units in the first display region complete display; in the first sub-frame, providing a second start signal to the second light-emitting control scan driving circuit so that the second light-emitting control scan driving circuit controls the second display region to not emit light; in the second sub-frame, providing the first start signal to the first light-emitting control scan driving circuit again so that the plurality of rows of first pixel units in the first display region complete the display; and in the second sub-frame, providing the second start signal to the second light-emitting control scan driving circuit so that the second light-emitting control scan driving circuit controls the second display region to not emit light. The second start signal and the first start signal are each applied independently, and the display panel may complete display scanning once within the time period of each image frame.
