More Information
Summary:A LED module comprises: a printed circuit board; a LED which is perpendicularly mounted to the printed circuit board and emits light to a side; and a contact member provided to contact a light guide plate. The printed circuit board is movably coupled to a bottom chassis and the LED module can move by applying a pressure to the contact member from the light guide plate when the light guide plate thermal-expands. The LED module is elastically supported by an elastic member. Thus, a space between the light guide plate and the LED can be kept constant even the light guide plate thermal-expands or restores to the original state.
