Abstract
Systems for displaying images are provided. A representative system comprises a signal driving circuit comprising a plurality of shift registers connected in series and controlled only by a first clock and a second clock, generating corresponding driving pulses in turn in response to a start pulse. Each shift register comprises a pulse generation unit with a first clock input terminal receiving one of the first and the second clocks and a first power terminal coupled to a first power voltage, and a leakage protection unit coupled to the pulse generation unit, electrically separating the first power voltage from the received clock at the first clock input terminal.
