Patent ID: 7609243

Claim:
A liquid crystal display apparatus that corrects optical response characteristics of a liquid crystal display panel, by subjecting image data supplied to the liquid crystal display panel to enhancing conversion at least in accordance with image data of a directly previous vertical period and image data of a current vertical period, the liquid crystal display apparatus comprising: signal type detection section for detecting whether a signal type of input image data is a progressive signal or an interlace signal; I/P conversion section for converting an interlace signal to image data that is a quasi-progressive signal, if the input image data is an interlace signal; and enhancing conversion section for subjecting the image data to overshoot enhancing conversion, in a direction of gray level transition, when the enhancing conversion section subjects the quasi-progressive signal to the overshoot enhancing conversion in accordance with a result of detection performed by the signal type detection section, the enhancing conversion section performs such enhancing conversion that when the input image data is an interlace signal, the degree of the enhancing conversion of the image data is lower than when the input image data is a progressive signal.
