Method and system for driving light emitting diode (LED) lamp

The present invention discloses a liquid crystal display panel and a driving method of an LED lamp system in the field. A correspondence relationship between the channel port of the present invention to adjust the first port and the LED chip of the LED lamp driver; channel port correspondence relationship is then connected to the port and the LED chip LED lamp driver in accordance with the adjusted control the LED to emit light. The present invention avoids the overheating of the LED lamp driver even burned chip LED lamp driver chip; adaptation can be various LED lamps, the LED lamp failure rate will work to a minimum; effectively reduce the concentration of heat generation chip LED lamp driver, improve the life of the LED lamp driver chip.
