    • The present invention provides a display device which includes a common electrode drive circuit having the single channel constitution which can miniaturize a circuit scale without increasing elements compared to a conventional display device. A display device includes a plurality of pixels and a common electrode drive circuit. The common electrode drive circuit includes a plurality of basic circuits, wherein the basic circuit includes a first circuit which latches a first input signal at a point of time that a clock signal is changed to a first voltage level from a second voltage level; a second circuit which latches a second input signal at the point of time that the clock signal is changed to the first voltage level from the second voltage level; a first switching circuit which is turned on based on the first circuit and a second switching circuit which is turned on based on the voltage second circuit.
    • 本发明提供了一种显示装置,其包括具有单通道结构的公共电极驱动电路,其可以与常规显示装置相比能够使电路规模小型化而不增加元件。 显示装置包括多个像素和公共电极驱动电路。 公共电极驱动电路包括多个基本电路,其中基本电路包括第一电路,其在时钟信号从第二电压电平变为第一电压电平的时间点锁存第一输入信号; 第二电路,其在时钟信号从第二电压电平改变为第一电压电平的时间点锁存第二输入信号; 基于第一电路接通的第一开关电路和基于电压第二电路导通的第二开关电路。
