Method for manufacturing light emitting diode backlight module

Abstract

A method to manufacture an LED backlight module comprising steps: providing a substrate with circuits arranged thereon; pasting a plurality of LEDs on the substrate; electrically conducting the LEDs with the circuits on the substrate; providing a luminance photometer to measure an illumination of the LEDs in luminous state and getting an actual light intensity distribution of the light of the LEDs through a brightening sheet and a diffusion sheet; providing a computer to detect whether the actual light intensity distribution has a dark/bright band/spot. If the actual light intensity distribution is uniform, the LEDs are soldered to the substrate directly. If there is dark/bright band/spot, the positions of LEDs in connection with the irregular light band/spot are adjusted to enable the light from the LED backlight module to have a uniform intensity distribution.
