Abstract

The invention provides a display panel, a display device and a driving method, so as to solve the problem that when a folding display panel in the prior art displays on a half screen, the half screenwhich is not displayed has disordered display. The display panel comprises a display area, and the display area comprises a first display area, a second display area and a plurality of pixel driving circuits arranged in an array mode; a plurality of first power lines and a plurality of second power lines, wherein each of the first power lines and each of the second power lines extend along the column direction of the pixel driving circuit; the first power line is positioned in the first display area and is electrically connected with the pixel driving circuit in the first display area; the second power line is positioned in the second display area and is electrically connected with the pixel driving circuit in the second display area; the first power line and the second power line are disconnected from each other.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a driving method. Background technique [0002] With the development of flexible display substrate technology, foldable display panels are gradually being applied. When some foldable display panels are in use, when in a folded state, a part of the display panel is a display area, and the rest is a non-display area; when in an unfolded state, the entire display panel is a display area. [0003] However, when the foldable display panel in the prior art is displaying half the screen, the non-displayed half screen has the problem that disorderly display is likely to occur. Contents of the invention [0004] The present invention provides a display panel, a display device and a driving method, so as to improve the problem that the non-displayed half-screen is prone to messy display when the folding display panel in the prior art is dis...
