    • PURPOSE: A reflective display device is provided to reduce voltage difference between the source and drain of a thin-film transistor (TFT), thereby preventing deterioration of an element oxide film. CONSTITUTION: A pixel array is composed of multiple pixels. A data driver (130) is connected to each of the multiple pixels and delivers a target voltage to each pixel. A scan driver (150) is connected to each of the multiple pixels and delivers a switching signal, determining whether the data driver delivers the target voltage, to a part of the multiple pixels. Each pixel receives the target voltage in a first time section if the target voltage delivered to each pixel is between a first voltage level and a second voltage level, and receives the target voltage in a second time section if the target voltage is between the second voltage level and a third voltage level.
    • 目的:提供一种反射显示装置,以减小薄膜晶体管(TFT)的源极和漏极之间的电压差,从而防止元件氧化物膜的劣化。 构成:像素阵列由多个像素组成。 数据驱动器(130)连接到多个像素中的每一个,并将目标电压传送到每个像素。 扫描驱动器(150)连接到多个像素中的每一个,并将确定数据驱动器是否传送目标电压的切换信号传送到多个像素的一部分。 如果传送到每个像素的目标电压在第一电压电平和第二电压电平之间,则每个像素在第一时间段中接收目标电压,并且如果目标电压在第二电压之间,则在第二时间段中接收目标电压 电平和第三电压电平。
