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.

摘要： Prior to increasing the voltage level of an input signal to be sampled in a step-by-step manner and writing a signal voltage Vsig at a desired voltage level, a precharge is performed which writes a precharge voltage Vpre, lower than the signal voltage Vsig, so as to apply the same voltage Vpre to the gate of a drive transistor in advance. This not only provides a reduced gate-to-source voltage of the drive transistor at the time of writing of the signal voltage Vsig but also extends a mobility correction time required for a mobility correction operation. The extension of the mobility correction time required for the mobility correction operation ensures a relatively smaller variation in the correction time, thus suppressing the variation in brightness. The extension also permits a write pulse to be set to the optimal pulse width.

摘要翻译： 在以逐步方式增加要采样的输入信号的电压电平并且将信号电压Vsig写入期望的电压电平之前，执行预充电，其写入比信号电压Vsig低的预充电电压Vpre ，以便预先将相同的电压Vpre施加到驱动晶体管的栅极。 这不仅在写入信号电压Vsig时提供驱动晶体管的栅极 - 源极电压降低，而且还延长迁移率校正操作所需的迁移率校正时间。 移动性校正操作所需的迁移率校正时间的延长确保校正时间的相对较小的变化，从而抑制亮度的变化。 扩展还允许将写入脉冲设置为最佳脉冲宽度。
