Abstract
A gate-on voltage generator that can enhance display quality at low temperatures, a driving device, and a display apparatus having the same, in which the gate-on voltage generator includes a temperature sensor having an operational amplifier configured to receive a driving voltage and produce a temperature-dependent variable voltage, the level of which varies according to the ambient temperature, and a charge pumping unit shifting the temperature-dependent variable voltage by the voltage level of a pulse signal and generating a gate-on voltage.
