Abstract
A driving apparatus for a liquid crystal display capable of adjusting a field area displayed on a liquid crystal display panel at the exterior thereof is disclosed. In the apparatus, an image signal processor separates a television image signal from a complex image signal and separates a complex synchronizing signal. A liquid crystal display panel displays the television image signal. A timing controller generates a source start pulse determining a display start time of the television image signal displayed on the liquid crystal display panel using an internal clock signal and the complex synchronizing signal from the image signal processor. A delay circuit delays the internal clock signal to apply it to the timing controller.
