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.

Backlight module

The present invention provides a light guide plate and a backlight module, wherein the light guide plate comprises a bottom surface, a light incident surface and a light-emitting surface. The light-emitting surface and the bottom surface are positioned oppositely. The bottom surface comprises a plurality of screen dots. The screen dots comprise fluorescent powder and are selectively added with diffusion particles. The present invention prevents the phenomenon of color shift and the luminous efficiency degradation due to the fluorescent powder accelerated ageing because of closing to the LED chip.

Light guide plate and backlight module

The present invention discloses a backlight module and a liquid crystal display apparatus. The backlight module is employed in a liquid crystal display apparatus having a back plate and a plurality of LEDs. The liquid crystal display apparatus has a display area in accordance with the back plate and overlaps therewith, and the display area has a display area center line. The display area center line has a center corresponding to the LEDs. The LEDs are classified to belong to several positive voltage bins respectively. The LEDs belonging to a lower positive voltage bin are positioned closer to the center and the LEDs belonging to a higher positive voltage bin are positioned farther to the center.
