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

摘要

PURPOSE: A driving device of a light source module, a light source device with the driving device, a driving method of the light source module and a display device with the driving device are provided to synchronize a driving signal applied to a light emitting block with the first reference clock. CONSTITUTION: A phase adjusting unit(320) sets a phase compensation quantity to make the sum with a phase delay quantity to become an integer multiple size of a period of the first reference clock. The phase adjusting unit delays a phase of the first reference clock by the phase compensation quantity to generate the second reference clock. A local dimming driving unit(240) analyzes an image signal supplied from the outside. The local dimming driving unit determines a dimming level of each light emitting block. The local dimming driving unit synchronizes the light emitting block with the first reference clock to drive based on the second reference clock and the dimming level.
