ABSTRACT:
A picture display apparatus exploiting a liquid crystal display is disclosed. This picture display apparatus (10) includes an interpolator (11), an over-drive unit (12), an angle of visibility improvement unit (13), and a source driver (15) for driving a liquid crystal display panel (16). The interpolator converts the picture rate upwardly. The angle of visibility improvement unit (13) converts an input picture signal into a picture signal representing a grayscale level of the input picture signal by synthesis of liquid crystal transmittances of a plural number of temporally consecutive fields. Specifically, the angle of visibility improvement unit converts the input picture signal to a picture signal made up of a first field set to a signal value related with a high grayscale level and a second field set to a signal value related with a low grayscale level. In case time changes of the grayscale level have occurred in the input picture signal at the same spatial position, the over-drive unit (12) corrects the driving level for a signal value of one or both of the first and second fields depending on response of the liquid crystal.
