METHOD OF DRIVING LIGHT-SOURCE, LIGHT-SOURCE APPARATUS PERFORMING FOR THE METHOD AND DISPLAY APPARATUS HAVING THE LIGHT-SOURCE APPARATUS

摘要

PURPOSE: A method for driving light-source, a light-source apparatus performing for the method and a display apparatus with the light-source apparatus are provided to remove waterfall noise and low frequency noise cause by the frequency of the light source drive signal. CONSTITUTION: A display device comprises a display panel(100), a timing control unit(110), a panel driving unit(130), an optical source module(200) and a light source driving unit(290). The panel driving unit runs a display panel with synchronizing signal and video signal. The light source driving unit comprises an image analysis part(210), a dimming level decision unit(230), a driving signal generation unit(250) and a driving signal transform unit(270).
