Abstract
A liquid crystal display driving apparatus including a pixel voltage driving circuit for providing a periodical pulse high-voltage signal is provided. The liquid crystal display driving apparatus includes: a gate driving unit, a source driving unit, and a gate line and a date line intersected with each other to define a pixel region, in which a pixel electrode is provided, wherein the source driving unit includes: a pixel voltage driving circuit for providing a unidirectional voltage signal applied to the pixel electrode in the pixel region and for providing a periodical pulse high-voltage signal; and a common voltage driving circuit for providing a common voltage signal which corresponds to the unidirectional voltage signal provided by the pixel voltage driving circuit.
