    • A driving circuit for an LCD device, and a method for driving the same, that minimizes RC delay is provided. The driving circuit includes a clock signal generating unit for outputting a clock signal at a predetermined period; a plurality of latches connected in series for sampling inputted digital data, and shifting and storing the sampled digital data to the next latch in the series; a holding latch unit for simultaneously reading and outputting the sampled digital data stored in the plurality of latches; and a digital-to-analog converter unit for converting the sampled digital data outputted from the holding latch unit to analog data, and applying the analog data to data lines of an LCD panel.
    • 提供了用于LCD装置的驱动电路及其驱动方法,其使RC延迟最小化。 驱动电路包括用于以预定周期输出时钟信号的时钟信号产生单元; 多个串联连接的锁存器,用于对输入的数字数据进行采样,并将采样的数字数据移位和存储到该系列中的下一个锁存器; 保持锁存单元,用于同时读取和输出存储在多个锁存器中的采样数字数据; 以及数模转换器单元,用于将从保持锁存单元输出的采样数字数据转换为模拟数据,并将模拟数据应用于LCD面板的数据线。
