Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method to manufacture an LED (light emitting diode) backlight module comprising steps: providing a substrate with circuits arranged thereon; pasting a plurality of LEDs on the substrate, wherein positions of the plurality of LEDs are movable and the LEDs are in electrical connection with the circuits; providing a luminance photometer and measuring an illumination of the LEDs in luminous state and getting an actual intensity distribution of light genera…
