Abstract
A printed circuit board assembly and a liquid crystal display (“LCD”) having the same, and more particularly, to a printed circuit board assembly, wherein a board mounted with a heat dissipation plate and a time controller using a spring clip or a hook spring can prevent the board from sagging. An exemplary embodiment includes a heat dissipation plate, a protection plate and a thermal interface material to dissipate heat from a time controller, thereby efficiently dissipating heat from the time controller. Another exemplary embodiment includes a spring clip or a hook spring to increase contact forces among a protection plate, a heat dissipation plate and a board, thereby further improving heat dissipation performance. Exemplary embodiments of the present invention make it possible to provide a printed circuit board assembly, wherein a spring clip supports the bottom of a region of a board in which a time controller is mounted, thereby preventing sagging of the region of the board in which the time controller and a heat dissipation plate are mounted. An LCD having the printed circuit board assembly is also described.
