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。
