Abstract

A light-emitting diode (LED) backlighting module and a method for manufacturing the same are described. The light-emitting diode backlighting module comprises a print circuit board (PCB), a plurality of light-emitting diode chips and a plurality of solder films. A plurality of conducting lines are located on a surface of the print circuit board, and the print circuit board comprises a plurality of openings. The light-emitting diode chips are disposed respectively in the openings. Each light-emitting diode chip comprises: a metal substrate; three light-emitting diode dies respectively located on a surface of the metal substrate; and a plurality of electrodes respectively located on the rim of the metal substrate, wherein two poles of each light-emitting diode die are electrically connected to the electrodes respectively. The solder films electrically connect the conducting lines of the print circuit board and the electrodes of each light-emitting diode chip.
