Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0044] In the following description, a lot of specific details are set forth in order to fully understand the application, but the application can also be implemented in other ways different from those described here, and those skilled in the art can do without violating the connotation of the application. By analogy, the present application is therefore not limited by the specific embodiments disclosed below.

[0045] As mentioned in the background section, with the increase of the...

Abstract

The embodiment of the invention discloses a display panel, a driving method thereof and a display device.The display panel comprises N types of display areas, the N types of display areas comprise the ith type of display area and the jth type of display area, the display panel comprises M display parts, the M display parts comprise the first display part and the second display part, the first display part comprises at least one ith type of display area, and the second display part comprises at least one jth type of display area. The first display part comprises at least one ith display area, the second display part comprises at least one ith display area, at least one jth display area is arranged between the ith display area included in the first display part and the ith display area included in the second display part, and the luminous time periods of the ith display area and the jth display area are at least partially not overlapped so as to reduce the same time period. The number of the sub-pixels driven by the power supply voltage line in the display panel is reduced, so that when the sub-pixels emitting light in the same time period emit light with the same brightness, the rising amplitude of instantaneous current on the power supply voltage line is reduced, the voltage drop on the power supply voltage line is reduced, and the uniformity of a display picture is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel, a display device including the display panel, and a driving method of the display panel. Background technique [0002] With the development of display technology, the application of display panels is becoming more and more common, and users have more and more requirements on the display quality of display panels. In order to meet the user's ever-increasing display quality requirements for display panels, under the same size, the number of display units included in the display panel is increasing, so that the resolution of the display panel is getting higher and higher, so as to improve the display screen of the display panel. richness. [0003] At present, a pulse width modulation (PWM) driving circuit has been widely used in the display panel to control the duration of the driving current of the light-emitting element in the display unit, so as t...
