    • A data driving circuit receiving an image signal and applying a data signal based on the image signal to a display panel, the data driving circuit includes a signal generator that generates a horizontal scanning identical signal based on the image signal and a load signal instructing an output of the data signal to the display panel; a signal amplifier that alternately converts a polarity of an offset compensation value from positive to negative and amplifies the image signal based on the offset compensation value; and a controller that counts pulses of the horizontal scanning identical signal and controls the signal amplifier to retain the converted polarity of the offset compensation value until a counted reaches a predetermined reference value.
    • 数据驱动电路,接收图像信号,并将基于图像信号的数据信号施加到显示面板,所述数据驱动电路包括信号发生器,该信号发生器基于图像信号生成水平扫描相同的信号,以及指示输出的负载信号 的数据信号发送到显示面板; 信号放大器,其将偏移补偿值的极性从正负转换为负,并且基于偏移补偿值放大图像信号; 以及控制器,其对所述水平扫描相同信号的脉冲进行计数,并控制所述信号放大器以保持所述偏移补偿值的转换极性,直到计数达到预定参考值。
