发明名称 Gate-off volatage generating circuit, driving device and liquid crystal dispaly including the same
摘要 A gate-off-voltage-generating circuit that can enhance display quality at low temperatures, a driving device, and a liquid crystal display having the same are provided. The driving device includes a boost converter to receive and boost a first input voltage, and output a driving voltage and a pulse signal; a gate-on voltage generator to receive the driving voltage and output a gate-on voltage; and a gate-off voltage generator including a first temperature-compensation unit to receive the driving voltage and output a first temperature-dependent variable voltage, the level of which varies according to the ambient temperature, a first voltage follower to receive and transfer the first temperature-dependent variable voltage, and a first charge-pumping unit to shift the first temperature-dependent variable voltage by the amplitude of the pulse signal and output a gate-off voltage.
