    • A method of compensating for channel interference of a display apparatus and a device for controlling driving of a data signal are provided. The method of compensating for the channel interference of the display apparatus includes: receiving pixel data of a scan line selected from an external screen memory; summing up the received pixel data and detecting a compensation time for compensating for channel interference which occurs in the selected scan line by using the sum of the pixel data; and adjusting at least one of a discharge time and a peak boost time of a driving current that is output to each data line according to the detected compensation time. Accordingly, it is possible to solve problems such as an increase of the circuit size caused by the existing compensation for the channel interference by controlling the discharge period or peak boost period with respect to each scan line and compensating for the channel interference phenomenon.
    • 提供了补偿显示装置和控制数据信号驱动装置的信道干扰的方法。 补偿显示装置的信道干扰的方法包括:接收从外部屏幕存储器中选择的扫描线的像素数据; 对所接收的像素数据求和,并通过使用像素数据的和来检测在所选择的扫描行中发生的信道干扰的补偿时间; 以及根据检测到的补偿时间来调整输出到每个数据线的驱动电流的放电时间和峰值升高时间中的至少一个。 因此,可以通过控制相对于每个扫描线的放电周期或峰值升高周期并补偿信道干扰现象来解决由现有的信道干扰补偿引起的电路尺寸增加的问题。
