Abstract: A backlight module is provided, which includes a plurality of single color light-emitting diodes (LEDs), an optical control film and a plurality of wavelength converting layers. The display panel includes a substrate and circuit elements. The optical control film having a plurality of through holes and being located above the plurality of single color LEDs. The plurality of wavelength converting layers disposed between the optical control film and the plurality of single color LEDs, wherein each of the wavelength converting layers corresponds to one of the single color LEDs and converts a light emitted from the one of the single color LEDs to white light.

Abstract: A backlight module includes a reflection base plate, at least one light source, at least one 3D optical control structure and a reflector. The light source is disposed on the reflection base plate. The 3D optical control structure is disposed on the reflection base plate and covers the light source. The 3D optical control structure includes a top surface and a lateral connected to the top surface. The lateral obliquely faces toward the reflection base plate, and an acute angle exists between the lateral and the reflection base plate. The reflector is disposed on the reflection base plate and beside the lateral. Light emitted from the light source passes through or is reflected by the top surface or the lateral, wherein a part of light passing through the lateral is reflected by the reflector so as to transmit toward a direction away from the reflection base plate.
