The backlight module includes a covering layer, an optical film, and a plurality of pins, the covering layer is disposed on the first surface of the base plate, and the pins are disposed between the covering layer and the optical film.

The backlight module includes multiple backlight units. Each backlight unit includes a first light emitting unit and multiple second light emitting units. The first light emitting unit has a first beam angle, and each second light emitting unit has a second beam angle which is narrower than the first beam angle. In a first mode, a light intensity of the first light emitting unit is equal to a first intensity, and a light intensity of the second light emitting units is equal to a second intensity. In a second mode, the light intensity of the first light emitting unit is equal to a third intensity, and the light intensity of the second light emitting units is equal to a fourth intensity.

The present disclosure relates to a backlight module, a display module and an assembling method thereof. The backlight module includes: a backplane; a fixing member fixedly connected to the backplane; and an insertion clamp including a mounting portion fixedly connected to the fixing member, and a clamping portion for clamping to a circuit board inserted between the fixing member and the insertion clamp.

A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

To provide a backlight that reduces the number of LEDs used while facilitating the attempt to make the backlight smaller in thickness. On a mount substrate (11), LEDs (13) are mounted in a square lattice arrangement. Over a portion near the center of each unit of the square lattice, protrusions (15) of a diffusion plate (14) are disposed. Among light emitted from the LEDs (13), light traveling in lateral directions between the mount substrate (11) and the diffusion plate (14) is captured by the protrusions (15). The captured light is refracted and reflected by the interfaces of the protrusions (15), and diffused due to diffusing particles, with the result that the light is turned into upward illumination light.
