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.

Driver for plane fluorescent panel and television receiver having liquid

The present invention relates to a thin battery-containing structure for an electronic apparatus which includes a lock pin provided on a flexible arm of a battery holder. The lock pin is guided to a predetermined position by a guide/lock groove in a case by pressing a battery holder inward for installing a battery in the battery container of the case. The lock pin is disengaged by the guide/lock groove when further inward force is applied. Upon removal of such force, the battery holder is pressed out of the battery container.
