Abstract
The present invention discloses a backlight module which has a plurality of light-emitting diodes. The light-emitting diodes are divided into a plurality of light groups according to pitches between the adjacent light-emitting diodes. The light-emitting diodes with respect to a display-area center line have a position center, and the light group having the light-emitting diodes with larger pitches therebetween is in a position relatively close to the position center and is in a higher bright bin; the light group having the light-emitting diodes with smaller pitches therebetween is in a position relatively away from the position center and is in a lower bright bin. Therefore, luminous conditions of the overall light-emitting diodes tend to correspondence, and proportion of usage of light-emitting diodes in different bright bins can be increased.
