Display panel, fabrication and driving method thereof, and display device

A display device, comprising:

• a display panel, comprising:
• a substrate comprising a display area and a non-display area located in a periphery of the display area;
• a plurality of organic light emitting diodes located in the display area;
• a driving circuit located in the non-display area, the driving circuit being configured to provide driving signals to the plurality of organic light emitting diodes;
• a first signal line configured to electrically connect the driving circuit and the plurality of organic light emitting diodes;
• a second signal line configured to electrically connect the driving circuit and the plurality of organic light emitting diodes, wherein an orthographic projection of the first signal line on the substrate and an orthographic projection of the second signal line on the substrate are at least partly not overlapped;
• and
• a sacrificial line disposed adjacent to the first signal line and the second signal line, wherein the sacrificial line is electrically connected to a voltage supply element,
• wherein, in response to driving the display panel, the first signal line and the second signal line are configured to be provided with a first signal and a second signal, respectively, through the driving circuit, a level of the first signal being lower than a level of the second signal;
• and
• wherein the sacrificial line is configured to be provided a third signal through the voltage supply element, a level of the third signal being always higher than the level of the first signal and the level of the second signal;
• and
• a frame.
