Abstract: A flash phenomenon of OLEDs at the time of power source ON of a display device is suppressed. The OLED emits light when reference potentials VSS and VDD are applied from power source lines to the OLED's cathode and anode respectively. While the anode can be connected to one of the power source line via a driving TFT and a lighting switch, a reset potential VRS can be applied to the anode via a reset switch and the driving TFT. The lighting switch is turned OFF and the reset switch and the driving TFT are turned ON so that VRS is applied to the anode, before starting the application of the reference potentials to the power source lines. Following this state, the application of the reference potentials to the power source lines starts, and thus a normal operation of allowing the OLED to emit light starts.

Abstract translation: 抑制显示装置的电源ON时的OLED的闪光现象。 当参考电位VSS和VDD分别从电源线施加到OLED的阴极和阳极时，OLED发光。 当阳极可以经由驱动TFT和照明开关连接到电源线中的一个时，复位电位VRS可以经由复位开关和驱动TFT施加到阳极。 在开始向电源线施加参考电位之前，点亮开关被关闭并且复位开关和驱动TFT导通，使得VRS被施加到阳极。 在该状态之后，开始对电源线施加参考电位，因此开始允许OLED发光的正常操作。
