Abstract

An apparatus and method for controlling automatic adjustment of a power supply of a display panel driving system. According to the apparatus and method, a voltage of the power supply of the display panel driving system is automatically adjusted in order to have the best possible image quality. According to the apparatus and method, since the PDP driving power supply is not manually adjusted using the variable resistors as in the related art, but is automatically adjusted. The apparatus manufacturing process is simple, and deviation caused by the automatic adjustment of the power supply is decreased compared with the manual adjustment of the related art, by automatically adjusting the PDP driving voltage affecting to the contrast deviation and brightness deviation of the PDP image in the PDP driving power supply circuit so as to maintain the best possible image quality.
