ABSTRACT:
A video signal processing apparatus chiefly has a peripheral circuit, a low-voltage processing circuit for controlling image quality, a high-voltage processing circuits for converting into a signal for a liquid crystal display panel, and the liquid crystal display panel. Signal separation is performed in two stages, in the low-voltage processing circuit and the high-voltage processing circuits. The frequency characteristics of the low-voltage processing circuit are enhanced by decreasing the number of the separated sections thereof to two, while the frequency characteristics of the high-voltage processing circuits are suppressed by increasing the number of the separated sections thereof to twelve, and sufficient voltages therefor are provided.
