Patent ID: 8497833

Claim:
A display device comprising: a display unit comprising a plurality of scan lines for transmitting a plurality of scan signals, a plurality of data lines for transmitting a plurality of data signals, a plurality of light emitting signal lines for transmitting a plurality of light emitting signals, and a plurality of pixels coupled to the scan lines and the data lines and for emitting light according to the light emitting signals; and a light emission driver for transmitting the light emitting signals to the light emitting signal lines, and for controlling a pulse width of the light emitting signals, wherein the light emission driver is configured to: receive a synchronization signal for limiting a maximum value of a driving current flowing to the pixels, a first light emitting clock signal in synchronization with the synchronization signal, a second light emitting clock signal in synchronization with the synchronization signal and having the same frequency as the first light emitting clock signal and a phase difference from the first light emitting clock signal, a clock signal having the same frequency as the first light emitting clock signal, and an inverted clock signal of the clock signal; sequentially generate a plurality of first light emitting signals during a plurality of first light emitting clock signal periods, and generate a plurality of first inverted light emitting signals by sampling the clock signal during the first light emitting clock signal periods, in synchronization with edge timing of the first light emitting clock signal; and sequentially generate a plurality of second light emitting signals during a plurality of second light emitting clock signal periods, and generate a plurality of second inverted light emitting signals by sampling the inverted clock signal during the second light emitting clock signal periods, in synchronization with edge timing of the second light emitting clock signal.
