摘要： A driving unit of display panel includes a data driving part, a timing controlling part and a gate driving part. The data driving part is configured to receive reference image data and includes a first data driving circuit part having a first channel outputting a first reference data signal based on the reference image data and a k-th channel outputting a k-th reference data signal based on the reference image data. The timing controlling part is configured to detect a time difference between the first reference data signal and the k-th reference data signal. The gate driving part is configured to output a gate signal to each of gate lines. By delaying data signals based on the gate signal delay caused by long line load and RC delay, the present invention may improve display quality of a display device.
