Flexible display device and method for driving the same

A flexible display device, comprising:

• a main flexible display panel and at least one auxiliary flexible display panel stacked on the main flexible display panel, wherein:
• the main flexible display panel comprises a plurality of main pixel units spaced apart from each other, the auxiliary flexible display panel comprises a plurality of auxiliary pixel units spaced apart from each other, and orthographic projections of the auxiliary pixel units onto the main flexible display panel overlap with the main pixel units;
• the main flexible display panel is configured to, in the case that the flexible display device is stretched, enable at least a part of an orthographic projection of each main pixel unit of the main flexible display panel onto the auxiliary flexible display panel to be arranged between two adjacent auxiliary pixel units of the auxiliary flexible display panel, and/or
• the auxiliary flexible display panel is configured to, in the case that the flexible display device is stretched, enable at least a part of an orthographic projection of each auxiliary pixel unit of the auxiliary flexible display panel onto the main flexible display panel to be arranged between two adjacent main pixel units of the main flexible display panel.
