    • In a display device the possibility that the ratio between a display period for display signals and a display period for blanking signals differs from a preset ratio is eliminated, even when the video data is changed. A display device sequentially supplies blanking data from a data driver circuit which sequentially supplies display signals after a lapse of a given time from starting the supply of the display signals. In the display device, a ratio of display is set based on the blanking data per one frame period. Further, the number of pulses of a horizontal synchronizing signal is measured in one frame period contained in the video data, and a point of time is determined for starting display based on the blanking data in response to pulses of the horizontal synchronizing signal corresponding to the ratio based on a measured value of the number of pulses.
    • 在显示装置中,消除了显示信号的显示周期与消隐信号的显示周期与预设比率不同的可能性,即使视频数据被改变。 显示装置顺序地提供来自数据驱动器电路的消隐数据,数据驱动器电路在开始提供显示信号之后经过给定时间后依次提供显示信号。 在显示装置中,基于每帧周期的消隐数据来设置显示比率。 此外,在包含在视频数据中的一个帧周期中测量水平同步信号的脉冲数,并且响应于对应于视频数据的水平同步信号的脉冲,基于消隐数据确定开始显示的时间点 基于脉冲数的测量值的比率。
