LOCAL DIMMING METHOD, LIGHT-SOURCE APPARATUS PERFORMING FOR THE METHOD AND DISPLAY APPARATUS HAVING THE LIGHT-SOURCE APPARATUS

摘要

PURPOSE: A local dimming driving method, a light source device, and a display device thereof are provided to improve display quality by periodically compensating the color intensity of radiation. CONSTITUTION: A display device includes a display panel(100), a timing controller(110), a panel driver(150), and a light source device(BLU). The timing controller receives a synchronization signal(101) and a video signal(102). The timing controller generates timing signals for controlling a driving timing of the panel driver. The panel driver includes a gate driver(120) and a data driver(140). The light source device includes a light source module(200) and a local dimming driver(290).
