    • The invention provides a driving circuit for a liquid crystal device having a reduced number of transistor elements by sharing transistors having identical logics among adjacent decoders. The driving circuit for a liquid crystal device capable of carrying out gradation display by applying gradation voltage corresponding to a display data to a liquid crystal element comprises a decoder circuit portion composed of a dynamic circuit for selecting the gradation voltage, the decoder circuit portion having a number of transistor elements 4 reduced by sharing transistors with identical logics constituting adjacent decoders. The voltage level corresponding to the display data causes all the analog switches to be set to an off status, so as to prevent overlap of output voltage during a timing of transition of the analog switch to the off status and a timing by which the analog switch is turned on according to a subsequent display data.
    • 本发明提供了一种通过在相邻解码器之间共享具有相同逻辑的晶体管的晶体管元件数目减少的液晶装置的驱动电路。 能够通过将与显示数据对应的灰度电压施加到液晶元件的能够进行灰度显示的液晶装置的驱动电路包括由用于选择灰度电压的动态电路组成的解码器电路部分,解码器电路部分具有 通过共享具有构成相邻解码器的相同逻辑的晶体管来减少晶体管元件4的数量。 对应于显示数据的电压电平使得所有模拟开关被设置为关闭状态,以防止在模拟开关转换到关闭状态的定时期间的输出电压的重叠以及模拟开关 根据随后的显示数据被打开。
