<P>PROBLEM TO BE SOLVED: To provide a display for preventing inclusion of noise in the tilt waveform of a control signal. <P>SOLUTION: A power supply pulse generation circuit 7 includes a pair of power supply lines, an output terminal VDDWS2 for supplying a power supply pulse to a scanner, a first transistor Tr1 connected between one power supply line VDDWS and an output terminal VDDWS2, a second transistor Tr2 and a third transistor Tr3 connected between a ground line which is the other power supply line and the output terminal VDDWS2, a control unit for turning ON the second transistor Tr2 and the third transistor Tr3 to tilt the waveform of the power supply pulse after the first transistor Tr1 is turned OFF, and a protection part 8 for preventing turning-ON of the first transistor Tr1 of the OFF-state due to coupling generated when the second transistor Tr2 is turned ON. The power supply pulse having the noise thus removed is transmitted as an original waveform of the control signal to the scanner of a display panel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
