Abstract: Provided is an OLED display device that is in a black mode in which a threshold voltage of a driving TFT need not accurately be sensed. Further, a low voltage value of zero or less is constantly and continuously supplied to a data line during an initialization period, a sampling period, and a programming period in a pixel. As a result, when the pixel is driven in the black mode, a reference voltage and a data voltage having different values are not alternately supplied to the data line to minimize power consumption.
Abstract translation: 提供一种处于黑色模式的OLED显示装置，其中驱动TFT的阈值电压不需要被精确地感测。 此外，在像素中的初始化期间，采样周期，编程周期期间，将一个零或更小的低电压值恒定地连续提供给数据线。 结果，当以黑色模式驱动像素时，不会将具有不同值的参考电压和数据电压交替地提供给数据线以使功耗最小化。
