Abstract
A source driver of an LCD includes a first and second power sources, a first and second inversion units, a first and second charging switches, and a first and second discharging switches. The first charging switch is coupled to the first power source, a first end of the first inversion unit, and a second end of the second inversion unit. The second charging switch is coupled to the first power source, a first end of the second inversion unit, and a second end of the first inversion unit. The first discharging switch is coupled to the second power source, the second end of the first inversion unit, and the first end of the second inversion unit. The second discharging switch is coupled to the second power source, the second end of the second inversion unit, and the first end of the first inversion unit.
