DRIVING CIRCUIT AND LIQUID CRYSTAL DISPLAY APPARATUS HAVING THE SAME

摘要

A driving circuit and a liquid crystal display apparatus having the same are disclosed. The driving circuit includes a first clock-signal driving circuit, a second clock-signal driving circuit, a data-line driving circuit, and a scanning-line driving circuit. The driving circuit and the liquid crystal display apparatus having the same prevent the delay of primary scanning signals so as to solve a technical problem where conventional liquid crystal display apparatus display images with a low display quality due to the delay of primary scanning signals.
