Abstract:
A display device comprising:a display panel having a plurality of pixels arranged in a matrix form; a signal drive circuit for generating a tone voltage corresponding to display data; a scan drive circuit for generating a scan voltage for selecting a row of a pixel to which the tone voltage is applied; tone voltage lines coupled to said signal drive circuit and said plurality of pixels, for transferring the tone voltage from said signal drive circuit to said plurality of pixels; scan voltage lines coupled to said scan drive circuit and said plurality of pixels, for transferring the scan voltage from said scan drive circuit to said plurality of pixels; and a correction circuit for correcting post-change display data in a current frame input to said signal drive circuit, based on a differential between before-change display data of a preceding frame and post-change display data of the current frame where the display data between two consecutive frames changes, wherein said correction circuit corrects said post-change display data of the current frame so that said pixel has a response characteristic such that on a characteristic graph where an ordinate indicates a response time and an abscissa indicates said post-change display data of the current frame relative to said before-change display data of the preceding frame, a response time of said post-change display data of an intermediate change quantity between said post-change display data of a minimum change quantity and said post-change display data of a maximum change quantity is plotted in a concave trace with respect to a reference of a straight line connecting a response time of said post-change display data of the minimum change quantity and a response time of said post-change display data of the maximum change quantity.
