Background technique
Backlight module (Back light module, abbreviation backlight (BL)), is liquid crystal display panel (LCD panel)
One of key component.Since liquid crystal itself does not shine, the function of backlight is the light source supplying enough brightness Yu being evenly distributed,
Panel of LCD is set normally to show image.The backlight module of mobile phone is generally by reflective membrane, light guide plate, lower diffusion
Film, lower bright enhancement film, upper bright enhancement film, upper diffusion barrier, LED lamp bead, glue frame and edge etc. are constituted.It is shone by LED lamp bead, through leading
Tabula rasa is broken up to be shone to become to push up by side and shine, then by several layers of diaphragm optically focused, so that backlight surface uniformly light-emitting, general glue frame knot
Structure problem, in glue frame, there are slight gaps with diaphragm avris, so that backlight module side light leakage, common solution is silk at present
The extinction ink extinction of a circle black is printed off, but ineffective and at high cost.
On the other hand, white light LEDs are now generally used, colour gamut commonly reaches about NTSC 60~80%, with consumer
The promotion required for image quality, it is desirable that picture has more lively bright-coloured performance, the gamut range of prior art performance without
Method meet demand, therefore the colour gamut of liquid crystal display how is widened, requirement of the people to color can be met, be always to grind
The hot spot that the person of studying carefully pay close attention to.
Quantum dot one kind has dimensions less than the nano semiconductor material of the crystalline texture of exciton Bohr radius (2-10nm),
Different launch wavelengths can be obtained by adjusting the partial size of particle, have the characteristics that emission spectrum is narrow and spectrum is continuous, take
With colored filter, it can express NTSC100% or higher colour gamut.When quantum dot film is arranged as backlight module, use
Blue-ray LED makes blue light be converted into white light (tri- color of RGB) in quantum dot film and is emitted as light source.However, in reality
The brightness and the decline of evenness degree of backlight module can equally be led to due to the leakage of side blue light in, and blue light is to human eye
Harm it is larger.

Glue frame at the top of be additionally provided with edge, edge is pressed on diffusion barrier, and the glue frame includes bottom plate and side plate, side plate setting
Be provided with step in bottom plate two sides, and in side plate and back plate connections, the reflective membrane, light guide plate, lower diffusion barrier, under add lustre to
Film, upper bright enhancement film, upper diffusion barrier are successively set on bottom plate, and reflective membrane, light guide plate are between step, and light guide plate upper surface
With step at the top of flush, lower diffusion barrier, lower bright enhancement film, upper bright enhancement film, upper diffusion barrier are placed on step, be completely covered reflective membrane,
Light guide plate.
Above-mentioned technical proposal is improved further and is refined, the bottom plate, side plate, step are integrally formed.
Above-mentioned technical proposal is improved further and is refined, the lower diffusion barrier is quantum dot diffusion barrier.
Above-mentioned technical proposal is improved further and is refined, the quantum dot diffusion barrier include upper barrier film, under
Barrier film and quantum dot layer, the upper barrier film are arranged in parallel with lower barrier film, between upper barrier film and lower barrier film
Even spread has quantum dot, and quantum dot constitutes quantum dot layer.
Above-mentioned technical proposal is improved further and is refined, the upper barrier film and lower barrier film are 12-35 μ
M, quantum dot layer reduce backlight module integral thickness with a thickness of 20-50 μm, so that finished product is whole thinner, more attractive.
Above-mentioned technical proposal is improved further and is refined, the LED lamp bead is blue-ray LED, blue-ray LED cooperation
Quantum dot diffusion barrier effectively increases backlight module colour gamut.
