Abstract: A circuit includes a reference signal generating part configured to generate a plurality of reference signals having levels different from each other, a comparing part configured to compare a ripple signal with the reference signals to determine a level of the ripple signal, a compensating signal generating part configured to generate a compensation ripple signal corresponding to the level of the ripple signal, where the compensation ripple signal has a phase opposite to the ripple signal, and a push-pull circuit configured to stabilize the compensation ripple signal.

Abstract: A method of driving a display panel includes steps of generating a plurality of load signals, of which at least one load signal has a different timing from the rest of the load signals, generating data voltages synchronized to low periods of the load signals and outputting the data voltages to data lines. Accordingly, the data voltages synchronized to each of the load signals can be outputted to each of the data lines. A color coordinate problem occurring when applying a RGBW type may be solved by setting a charging time of a white sub-pixel different from the rest of the sub-pixels. Thus, display quality of a display apparatus including the display panel may be improved.

Abstract translation: 驱动显示面板的方法包括以下步骤：产生多个负载信号，其中至少一个负载信号与其余负载信号具有不同的定时，产生与负载信号的低周期同步的数据电压，并输出 数据电压到数据线。 因此，可以将与每个负载信号同步的数据电压输出到每条数据线。 可以通过设置与其余子像素不同的白色子像素的充电时间来解决应用RGBW类型时出现的色坐标问题。 因此，可以提高包括显示面板的显示装置的显示质量。
