Light emitting display device and driving method of the same

A method for driving a light emitting display device including a display panel configured to display an image, a data driver configured to supply a data voltage to the display panel, and a timing controller configured to control the data driver, comprising:

• identify activation event;
• transferring, to the data driver, data comprising a control packet and a data packet via an interface coupled between the timing controller and the data driver;
• and
• during conversion of the data packet into the data voltage, delaying a data latch operation during a latch hold period based on noise caused by the amplifier activation event in the data driver.

A data driver, comprising:

• a shift register configured to receive a data signal from a timing controller and output a clock signal;
• a latch configured to latch the data signal based on the clock signal;
• a digital to analog converter (DAC) configured to convert the data signal into data voltages to drive a display device;
• and
• an output amplifier circuit configured to output the data voltages,
• wherein the data driver is further configured to interrupt and delay latching of the data signal based on a latch hold signal associated with noise caused by an activation event of the output amplifier circuit.
