Abstract
An exemplary method for making backlight module frames includes: method includes: providing a first metallic sheet and a second metallic sheet, each of the first and second metallic sheets having at least two L-shaped portions connected side by side and oriented in the same direction; welding the two metallic sheets to form a plurality of connected semi-manufactured frames corresponding to s subsequent backlight module frame; and pressing the connected semi-manufactured frames to form a plurality of backlight module frames. The method costs less welding time and it is convenient for the backlight module frames to be mass-produced.
