Spread spectrum clocking interface apparatus of flat panel display

Abstract

A spread spectrum clocking interface apparatus of a flat panel display for compensating for a frequency difference between a first clock signal externally supplied to a timing controller and a second clock signal generated from a spread spectrum clocking unit. The spread spectrum clocking interface apparatus includes a storage unit, first and second counters, and a delay unit. The storage unit stores input data to be supplied to the flat panel display in a first-in/first-out (FIFO) manner in accordance with a write address and outputs the stored input data in the FIFO manner in accordance with a read-out address. The first counter counts the first clock signal in response to a display enable signal and outputs a result of the counting as the write address. The delay unit delays the display enable signal while the second counter counts the second clock signal in response to the delayed display enable signal and outputs a result of the counting of the second counter as the read-out address.
