SYNCHRONOUS SWITCHING EQUIPMENT FOR FLUORESCENCE LAMP

摘要

PROBLEM TO BE SOLVED: To provide a synchronous switching equipment for making a planner fluorescence lamp emit light in a back surface of a large-sized liquid crystal display(LCD) panel. SOLUTION: The synchronous switching equipment is equipped with a common electrode, a distribution electrode, a voltage conversion device, and a signal generator. The distribution electrode faces to the common electrode and aligns on a straight line. The length of each distribution electrode is shorter than that of the common electrode. Each voltage conversion device is electrically connected to the common electrode and one of the distribution electrodes. All voltage conversion devices are electrically connected to the signal generator. A 1st panel, a 2nd panel, and two side panels form a planner lamp which has a hollow space in the inside. A layer which consists of fluorescence coating is attached to the inner side surface of the 1st and 2nd panels. The distribution electrode and the common electrode are attached in each side of the hollow space. The planner fluorescence lamp emits light through the high-voltage synchronized signal generated with the signal generator and the voltage conversion device.
