    • PURPOSE: A compensation table generating system, a display apparatus having a brightness compensation table, and a generation method of a compensation table are provided to reduce the whole size of a brightness compensating table. CONSTITUTION: A compensation table generating system comprises a test signal supply unit(20), an image acquisition unit(30), a position information extraction unit(41), a compensation data calculation unit, and a brightness compensation table(50). The test signal supply unit supplies a test signal to a display panel. The image acquisition unit acquires test images displayed on the display panel. The position information extraction unit measures brightness distribution of the display panel and extracts representative position information based on the measured brightness distribution. The compensation data calculation unit calculates compensation data of each position. The brightness compensation table stores the representative position information and the compensation data.

    • 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.
