The display device includes an image signal processor which corrects an original image signal whose frame frequency is a first frequency or a second frequency different from the first frequency and outputs a corrected image signal, a first lookup table which stores image correction data corresponding to an (n−1)-th frame and an n-th frame that corresponds to the original image signal having the first frequency, and a display panel which displays an image corresponding to the corrected image signal. A second lookup table, which corresponds to the original image signal having the second frequency, is generated from the first lookup table, and the first or second lookup table is selected based on the frame frequency of the original image signal to output the corrected image signal.

摘要： A light source module includes a plurality of light-emitting blocks. A local-dimming driver drives the light-emitting blocks based on a received clock signal (first reference clock) and received dimming levels. The clock signal is input to a liquid crystal display panel and is also input to the local-dimming driver but is delayed within the local-dimming driver by fixed propagation delay. A delay modeling part performs modeling of the fixed propagation delay amount. The clock signal input to the local-dimming driver is first phase-compensated (delayed) by a phase compensation amount to synchronize the driving signals output by the local-dimming driver with the clock signal. The sum of the modeled propagation delay amount and the phase compensation amount is equal to an integral multiple of the period of the clock signal. The driving signal of the light-emitting blocks are synchronized and in phase with the clock signal.
