Abstract

An image signal processing circuit of a display apparatus includes: a color converter converting first image signals to a first brightness signal, a first color difference signal, and a second color difference signal; a brightness emphasizer outputting a second brightness signal obtained by emphasizing an alternating current component of the first brightness signal; a brightness limiter determining an upper limit value and a lower limit value based on the first color difference signal and the second color difference signal and converting the second brightness signal to a third brightness signal between the upper limit value and the lower limit value; and a color inverse converter converting the third brightness signal, the first color difference signal, and the second color difference signal to second image signals.
