DRIVING APPARATUS OF STEREOSCOPIC IMAGE ADAPTIVE DISPLAY

摘要

PURPOSE: A stereoscopic image adaptive display driving apparatus is provided to adjust a driving signal according to the selection of a stereoscopic image like 3D. CONSTITUTION: A DC/DC converter(110) converts a DC input voltage to a predetermined DC voltage through PWM(Pulse Width Modulation) method. A variable feedback circuit part(120) has a variable resistance varying according to a control voltage, and provides an error voltage corresponding to a voltage obtained by dividing an output voltage of the DC/DC converter using the variable resistance. A converting control part(150) generates a PWM gate signal according to the error voltage, and controls the operation of the DC/DC converter through PWM method using the PWM gate signal.
