摘要:
In a display apparatus, as shown in FIG. 1, by using a reference signal, a shift register and a logical operation circuit generate a driving signal in periods for correcting a threshold voltage based on a rectangular wave signal. Also by using the reference signal, a write signal in a mobility correcting period is generated by an inverter, a NAND circuit, a level conversion circuit, a buffer circuit, a driving power generating unit, and a low-pass filter including a resistor and a capacitor. The signals are separately generated and are selectively output. Thus, excessive or insufficient mobility correction based on emission brightness can be prevented.
