    摘要： When an organic EL display apparatus enables display of a standard luminance mode and a high luminance mode, it takes long time to reset the gate potential of the OLED drive TFT to a given value in a standard mode. In the reset operation of the gate potential of an OLED drive TFT at the time of writing an image signal, in a standard mode, a precharge current is allowed to flow in the OLED element for a short period before the reset operation to set an initial value of the gate potential of the OLED drive TFT to be close to a supply potential or a reference potential. With the above operation, the variation of the OLED drive TFT gate potential after resetting is reduced. As a result, the light emitting period during one frame can be extended. Also, since a blanking period can be extended, it is possible to measure the characteristic of the OLED element by using the blanking period.

    摘要翻译： 当有机EL显示装置能够显示标准亮度模式和高亮度模式时，以标准模式将OLED驱动TFT的栅极电位重置为给定值需要很长时间。 在写入图像信号时OLED驱动TFT的栅极电位的复位操作中，在标准模式下，允许预充电电流在复位操作之前在OLED元件中流动一段很短的时间，以设置初始 OLED驱动TFT的栅极电位的值接近电源电位或参考电位。 通过上述操作，复位后的OLED驱动TFT栅极电位的变化减小。 结果，可以延长一帧期间的发光周期。 此外，由于可以延长消隐期，因此可以通过使用消隐期来测量OLED元件的特性。
