SOCKET FOR LAMP CONNECTION, BACK LIGHT AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME

摘要

A socket for lamp connection, and a backlight unit and an LCD(Liquid Crystal Display) device using the same are provided to connect an inverter unit and socket units electrically by using a pin connection method, thereby simplifying a connection structure between the inverter and the socket units and minimizing the transmission distance of first and second lamp driving voltages to minimize a current leakage. A backlight unit includes plural lamps, a first socket unit(22), and a second socket unit(32). The plural lamps have first and second electrodes(42,44). The first socket unit has plural first sockets connected to the first electrode of each lamp. The second socket unit has plural second sockets connected to the second electrode of each lamp. The first and second socket units have substrates(20,30) and plural sockets. The substrates have common patterns to which first or second lamp driving voltage is supplied. The plural sockets supply the first or second lamp driving voltage from the common pattern to the first or second electrode of each lamp.
