摘要： A gate driving circuit has a first stage which includes: a pull-up driving unit which receives a first carry signal from a second stage and outputs a control signal having first, second, third and fourth voltages to a first node during a preliminary period, a gate active period, a first gate inactive period and a second gate inactive period, respectively; a pull-up unit which receives the control signal and outputs a gate-on signal to a second node during the gate active period; a carry output unit which receives the control signal and outputs a second carry signal to a third stage during the gate active period; and a pull-down unit which receives a gate-off signal and the second carry signal from the second stage and outputs the control signal having the fourth voltage level to the first node during the second gate inactive period.

摘要： A heater is provided with a bulb, a first heating element which has a negative temperature coefficient of resistance and a first rated heating power and forms a first coil in the bulb, a second heating element which has a positive temperature coefficient of resistance and a second rated heating power that is lower than the first rated heating power and is disposed in the bulb. The second heating element is placed adjacent to the first heating to heat the first heating element at an initial stage of a power supplying to the heater, thereby reducing resistance of the first heating element.
