Display device, driving device of display panel, and driving method thereof

A driving device of a display panel, comprising:

• a timing controller, providing a latch enable signal;
• a latch enable processing circuit, coupled to the timing controller, wherein the latch enable processing circuit generates a plurality of latch enable delay signals according to the latch enable signal, and provides a plurality of channel latch delay signals according to the latch enable delay signals, wherein the latch enable delay signals each have a different delay, one of the channel latch delay signals is one of the latch enable delay signals, and the channel latch delay signals vary with time by a time-varying control signal;
• and
• a source driver, coupled to the latch enable processing circuit and the display panel, wherein data lines of the display panel are grouped into a plurality of data channels, pixel data in the data channels are latched by the source driver, wherein the data channels are correspondence with the channel latch delay signals,
• the source driver transfers the pixel data of the data channels while a corresponding one of the channel latch delay signals is enabled, and enable time points of the channel latch delay signals are staggered according to the latch enable delay signals.
