Abstract
A flat panel display includes first and second signal drivers which drive a first and second group signal lines of a display panel in accordance with an input first and second group video data respectively. A controller controls a timing of sending the first group video data to the first signal driver via the first data line, and a timing of sending the second group video data to the second signal driver via the second data line. A delay time generating section shifts a relative timing between a timing at which the first signal driver receives the first group video data and a timing at which the second signal driver receives the second video data by a determined time. The problem of the deterioration of the EMI caused by synchronization of the peak currents respectively generated in signal drivers for driving a flat panel display can be suppressed.
