Abstract
A shift register circuit includes a driving signal generating circuit, a coupling circuit, and a sweep signal generating circuit. The driving signal generating circuit is configured to receive a plurality of first clock signals, a low voltage source, an initial signal, and a first high voltage source so as to output a driving signal. The coupling circuit is coupled to the driving signal generating circuit. The coupling circuit is configured to transmit the low voltage source. The sweep signal generating circuit is coupled to the coupling circuit. The sweep signal generating circuit is configured to receive a second clock signal, the low voltage source, and a second high voltage source so as to output a sweep signal. A waveform of the sweep signal includes an oblique waveform. The first high voltage source and the second high voltage source are electrically independent of each other.
