Abstract
Embodiments of the invention relate to a clock failure detection apparatus and method, and a timing controller of a liquid crystal display including the clock failure detection apparatus, and more particularly to a clock failure detection apparatus and method, by which a failed driving state of a liquid crystal display can be accurately and reliably detected and determined by monitoring a low voltage differential signaling (LVDS) clock using a clock of an oscillator for generating clocks of a predetermined frequency in a timing controller of the liquid crystal display when a clock failure is detected in operation of the liquid crystal display, and a timing controller including the clock failure detection apparatus.
