Abstract
A display device includes a backlight assembly and a panel assembly. The backlight assembly includes lamps which emit light when properly powered. Each of the lamps includes a lead terminal, and receives electric power through a lamp socket that is electrically connected to an external power supply. The lamp socket includes a socket cover inserted in the lamp socket. The socket cover supportively embraces a resilient contact terminal within the socket body and thus helps the contact terminal to maintain grip with the lead terminal. The socket cover includes a metal material that is able to absorb and safely dissipate heat impulses from nearby intermittent sparks, so that the socket cover is not substantially deformed by the heat impulses of multiple sparks that occur nearby at contact points between the lamp lead terminal and the socket contact terminal.
