Abstract
Provided are a display device and a driving method thereof. Each source drive integrated circuit (IC) of the display device includes a first random signal generator configured to generate a first random signal, a delay unit configured to generate first and second Source Output Enable (SOE) signals by randomly delaying an SOE signal in response to the first random signal, a first output group configured to output a data voltage at a first timing in response to the first internal SOE signal, and a second output group configured to output a data voltage at a second timing in response to the second internal SOE signal. The present disclosure utilizes a random signal generator to randomly disperse timings of SOE signals temporally and spatially within a source drive IC or between source drive ICs, thereby minimizing the peak current.
