Abstract: In an organic light-emitting display panel and an organic light-emitting display device, lighting lines arranged in the organic light-emitting display panel to be used for lighting inspection are connected to portions of power lines arranged in the organic light-emitting display panel, in which a voltage drop occurs. In a display driving period, a voltage the same as a voltage applied to the power lines is applied to the lighting lines. Then, the lighting lines can be used as auxiliary power lines, so that additional lines for compensating for the voltage drop are not required. Power compensation is enabled without increasing the voltage applied to the power lines. The uniformity of images can be improved without increasing power consumption.

Abstract: A bi-directional shift register can include a plurality of stages, an Nth stage among the plurality of stages including a first switching unit configured to receive a forward driving signal and a reverse driving signal, and control a Q-node; a second switching unit configured to receive an (N+2)th clock signal, and control a QB-node; a third switching unit configured to discharge the QB-node to a low-level voltage when the Q-node is charged to a high-level voltage, and discharge the Q-node to the low-level voltage when the QB-node is charged to the high-level voltage; and an output unit configured to output an Nth clock signal to an output terminal based on a voltage at the Q-node, in which the forward driving signal is an output signal from an (N−1)th stage or a forward start signal from an external source external to the shift register, and the reverse driving signal is an output signal from the (N+1)th stage or a reverse start signal from the external source.
