Abstract:
1. A drive circuit for a display apparatus, comprising: a shift register; and a pulse generation circuit for generating a drive pulse signal using an output pulse signal generated in the shift register, wherein the pulse generation circuit forms a pulse-starting edge and a pulse-termination edge of the drive pulse signal using a rise or a fall of pulse resulting from activation of the output pulse signal, the shift register is structured to generate pulses so that a rise of a pulse resulting from activation of the output pulse signal is sharper than a return fall of the pulse, or a fall of the pulse resulting from activation of the output pulse signal is sharper than a return rise of the pulse, the pulse-starting edge of the drive pulse signal is formed of a rise or a fall of a pulse resulting from activation of a first output pulse signal, and the pulse-termination edge of the drive pulse signal is formed of a rise or a fall of a pulse resulting from activation of a second output pulse signal.
