Abstract:
A driving voltage generating device, a display device including the same, and a method of generating a driving voltage are provided. The driving voltage generating device includes a driving voltage setting unit receiving initially set data on a driving voltage and a feedback voltage and outputting a control signal, a driving voltage trimmer receiving finely adjusted data on the driving voltage and adjusting the feedback voltage, and a DC to DC converter generating the driving voltage based on the control signal and an input voltage.
