Abstract

Provided are a power supply voltage control circuit and a method thereof, a driver integrated circuit, and a display device. The power supply voltage control circuit comprises: a voltage detection unit () configured to detect a power supply voltage (ELVDD, ELVSS) received by the display panel () from a power supply circuit (); a comparison unit () configured to obtain a voltage difference between the power supply voltage (ELVDD, ELVSS) and a reference voltage (VF,VF) through comparison; and a power supply voltage control unit () configured to transmit a power supply voltage control signal to the power supply circuit () according to the voltage difference and the reference voltage (VF,VF), so that the power supply circuit () outputs a corresponding power supply voltage to the display panel (), so as to compensate for the voltage drop loss during voltage transmission, optimize display effect of the product, reduce effectively the voltage drop loss from the output terminal of the power supply circuit to the display panel side can be, and ensure consistency of the voltages inputted into the display panel.
