ABSTRACT:
A driver is provided for driving a plane fluorescent panel as a backlight source in a small liquid crystal television receiver. The panel is driven with a pulse signal controlled such that a first edge of the pulse signal which is a rise or fall edge of the pulse signal is within a front porch of a horizontal blanking period of a video signal and that a second edge of the pulse signal which is a fall or rise edge of the pulse signal is within the width of a horizontal synchronous pulse to thereby drive the fluorescent panel efficiently to provide a stabilized light emission and render it difficult for noise in the fluorescent panel to enter the display of the television receiver. A small liquid crystal television receiver with a plane fluorescent panel driven so is also provided.
