PURPOSE: A light a display unit is provided to be applied to various display devices by including light emitting modules which are operated respectively. CONSTITUTION: An FPCB unit(10) includes a pulse line(11) and a minus line(12). The plus line includes a rectifying unit(13) and a control terminal(15). The minus terminal(18) is operated as the minus current terminal of a light emitting unit. An induction coil unit is arranged in the outer edge of the FPCB unit. An alternating current is induced from the induction coil unit. An alternating current is rectified by the rectifier. A rectified alternating current is charged by a battery.
