    Abstract: A display panel includes: a plurality of light emitting signal lines. Under a control of switching signals provided from a plurality of switching signal lines and control signals provided from a plurality of control signal lines, working gray scale level signals corresponding to respective display gray scales are written to corresponding sub-pixels in an order from small to large in working gray scale sequentially by a plurality of times in one frame display time through the plurality of light emitting signal lines. Different working gray scale level signals indicate have different durations, and each of the working gray scale level signals is provided to the organic light emitting diode via the second transistor through a light emitting signal line, and a final display gray scale is a gray scale caused by superimposing different working gray scale level signals.
