First and second driving pulses, which are different in shape, are alternately applied to each pixel of a liquid crystal matrix display panel. Each driving pulse comprises a high voltage portion and a low voltage portion. By changing the width of the high voltage portion, a half tone is obtained in a picture. The high voltage portion of the first driving pulse is formed along a leading edge of the pulse, and the high voltage portion of the second driving pulse is formed along a trailing edge of the pulse to offset capacitance noise caused by capacitive connections between data and scanning electrodes of the display panel.

System for driving a liquid crystal display panel

A television receiver having a liquid crystal display device includes a receiver having a electromagnetically shielded case and a receiving circuit provided in the shielded case and electrically connected to an antenna for producing audio signals and video signals. A liquid crystal display panel of the liquid crystal display device is electromagnetically shielded by a transparent and conductive shielding film for shielding the liquid crystal display panel.
