Abstract:
1. A display apparatus for executing a display corresponding to display data to be inputted from the outside, comprising: a display panel, a light-source for illuminating said display panel, and a controlling circuit for controlling light-emission luminance of said light-source irrespective of red, green and blue data of said display data, said controlling circuit switching said light-source between a 1st light-emission luminance and 2nd light-emission luminance during one period for updating said display data to said display, and said controlling circuit changing a time ratio of said 1st light-emission luminance and that of said 2nd light-emission luminance during said one period in accordance with said display data, wherein said controlling circuit comprises: a data storing unit for storing said display data by the amount of at least 1 frame, a data comparing unit for comparing corresponding pixels between said display data stored in said data storing unit and said display data to be inputted, and a pulse controlling unit for outputting a signal in correspondence with a comparison result by said data comparing unit, said signal controlling said time ratio of said 1st light-emission luminance in said one period.
