Patent ID: 7928942

Claim:
A signal-driving system, comprising: multi-stage cascaded shift register units, each stage of the multi-stage cascaded shift register units having a shift register including: an input for receiving an input pulse signal; an output for outputting a gate pulse signal; a driving unit for generating a driving pulse signal via a node based on a first clock signal, a second clock signal, and the input pulse signal; a first pull-up switch unit triggered by said driving pulse signal to output the gate pulse signal via the output based on either the first clock signal or the second clock signal; a first pull-down switch unit triggered by either said first clock signal or the second clock signal to electrically connect the output to a low-level voltage source; a carry switch unit triggered by said driving pulse signal to generate a pulse to an input of a next stage shift register unit based on either the first clock signal or the second clock signal; and a second pull-down switch unit triggered by a pulse from a carry switch unit of the next stage shift register unit to electrically connect said node to the low-level voltage source.
