Abstract

The embodiment of the invention provides a panel driving circuit, a display panel, a display device and a panel driving method. The panel driving circuit comprises at least two area driving circuits and at least one group of first switching devices, a group of first switching devices are arranged between the plurality of scanning signal lines of the adjacent area driving circuits, and in each group of first switching devices, first level signals of the control signal lines are received when the display areas corresponding to the adjacent area driving circuits are in a folded state, and the group of first switching devices are disconnected; and when the display area corresponding to the adjacent area driving circuit is in an unfolded state, a second level signal of the control signal line is received, and the group of first switching devices are switched on. According to the embodiment of the invention, when the display panel is in the folded state, partial display area display and partial display area screen turn-off can be realized, so that the technical problem of high power consumption of the foldable display panel can be solved.

Description

technical field [0001] The present application relates to the technical field of display panel driving, and in particular, the present application relates to a panel driving circuit, a display panel, a display device and a panel driving method. Background technique [0002] With the replacement of display devices, flexible screen technology has increasingly entered people's field of vision, and OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode, Organic Light-Emitting Diode) has gradually occupied the market year by year. OLED folding screens have attracted much attention for their thinness and shapeability. Due to the limitation of the folding mechanism of the OLED folding screen, the position of the battery is limited, and the capacity of the battery is limited, which puts forward the requirement of low power consumption for the display panel. [0003] In the prior art, the entire display area of ​​the foldable display panel is displayed, resulting in high p...
