ABSTRACT:
An apparatus and method are provided for driving an image display device by converting digital image data per pixel into an analog signal and driving a liquid crystal cell in response to the analog pixel signal, using a voltage charged with a driving circuit with a dual buffer structure. According to the apparatus, digital image data per pixel is converted into an analog signal to generate a voltage for driving an image display device, and an analog voltage for driving the image display device is generated using a driving circuit with a dual buffer structure. With the apparatus, it is possible to effectively prevent generation of undesired noise and display R.G.B. image signals using a single panel.
