Data driving circuit and display device having the same

Abstract

Disclosed are a data driving circuit of a display device and a display device having the same, the data driving circuit including: a latch circuit for latching a data signal in response to a latch enable signal and outputting a first signal; a level shifter for outputting a second signal obtained by changing a voltage level of the first signal; a digital-to-analog converter for outputting a third signal obtained by converting the second signal into an analog signal; an amplifier for outputting a fourth signal obtained by amplifying the third signal; a switch for outputting a fourth signal in the form of an image signal in response to the output enable signal; and a signal generator for generating a latch enable signal and an output enable signal. The signal generator adjusts a start time of an active duration of the latch enable signal such that the active duration of the latch enable signal begins after an inactive duration of the output enable signal begins.
