    • A data driver and a method of driving the same. The data driver includes a shift register for generating sampling signals; sampling latches for sampling digital data applied to output channels, respectively, in accordance with the sampling signals; holding latch units for receiving the sampled digital data of the channels from the sampling latches to hold the digital data for a first period; first digital-to-analog converters for receiving the held digital data of the channels from the holding latch units to generate currents corresponding to the digital data; a second digital-to-analog converter commonly connected to the channels and the first digital-to-analog converters to receive the digital data provided from the holding latch units for a second period and to generate correction currents for the data currents; and output stages for sampling, correcting, and driving final currents using the data currents and the correction currents.
    • 数据驱动器及其驱动方法。 数据驱动器包括用于产生采样信号的移位寄存器; 采样锁存器,分别根据采样信号对应用于输出通道的数字数据采样; 保持锁存单元,用于从采样锁存器接收采样的信道数字数据,以保持数字数据第一周期; 第一数模转换器,用于从保持锁存单元接收保持的信道数字数据,以产生对应于数字数据的电流; 通常连接到通道的第二数模转换器和第一数模转换器,用于接收从保持锁存单元提供的第二周期的数字数据并产生数据电流的校正电流; 以及使用数据电流和校正电流对最终电流进行采样,校正和驱动的输出级。
