Abstract: A liquid crystal display includes a signal controller to generate a plurality of start pulse signals based on a plurality of eye blinking signals during a predetermined mode of operation. The start pulse signals are generated in a manner different from a vertical synchronization signal. The start signals may be generated to have an irregular spacing which corresponds to the blinking signals, which may be different from a constant spacing used during display of moving images. The predetermined mode may be a still image mode.

Abstract translation: 液晶显示器包括信号控制器，用于在预定操作模式期间基于多个眨眼信号产生多个起始脉冲信号。 起始脉冲信号以与垂直同步信号不同的方式产生。 可以产生起始信号以具有对应于闪烁信号的不规则间隔，其可以与在运动图像的显示期间使用的恒定间隔不同。 预定模式可以是静止图像模式。

Abstract: A display device includes a display panel including a pixel coupled to first to fourth scan lines, an emission control line, and a data line, a scan driver which supplies a first scan signal to the first scan line, a second scan signal to the second scan line, a third scan signal to the third scan line, and a fourth scan signal to the fourth scan line, an emission driver which supplies an emission control signal to the emission control line, a data driver which supplies a data signal to the data line, and a timing controller which controls the scan driver, the emission driver, and the data driver. Each of the second and third scan signals has a gate-on level during a partial period of one frame, and is maintained at a gate-off level during a remaining period of the one frame, other than the partial period.

Abstract: A display device includes pixels including a light-emitting element, and an initialization transistor connected between an anode electrode of the light-emitting element and a first initialization power line to which a voltage of initialization power is supplied, and turned on when an initialization scan signal is supplied, and an initialization scan driver which supplies the initialization scan signal. The initial scan driver supplies an i-th (i is a natural number) initial scan signal to overlap an (i−1)-th initial scan signal, and supplies an (i+1)-th initial scan signal so as not to overlap the i-th initial scan signal, and the initialization scan signal is set to a gate-on voltage.
