Abstract

A backlight module for an LCD display includes backlight units. Each backlight unit includes a backplane unit, a first reflecting unit on the backplane unit, an LED on the backplane unit extending through the first reflecting unit, and a light guiding unit on a side of the LED and the first reflecting unit away from the backplane unit. The light guiding unit is transparent. Each backlight unit further includes a second reflecting unit on a side of the light guiding unit away from the backplane unit. The second reflecting unit includes at least one reflecting region and at least one transmitting region. The reflecting region reflects light; the transmitting region allows light to pass through. At least one backlight unit comprises a quantum dot layer.
