PROBLEM TO BE SOLVED: To overcome unevenness phenomenon, by providing a display device equipped with a control module for preventing harmonic disturbances. SOLUTION: The display device is adapted to receive an image signal having an image scanning frequency and includes an internal light source, a light source adjustment module, and a control module. The light source adjustment module has a pulse width modulation controller, generating an origin control signal, the control module has a frequency detection circuit and a plurality of range adjustment circuits. The frequency detection circuit controls the pulse width modulation controller, by operating one among the range adjustment circuits. COPYRIGHT: (C)2006,JPO&NCIPI
