Laser point light source 101 is incident from left or right-hand member, optically coupled Bao Weir lens 201, by laser from spot light
Become line source, special-shaped light guide plate 401 is entered by the plane of incidence 301 for being coated with anti-reflection film.The structure of scattering point is embedded with through bottom
To being reflected and being scattered into light therein, mix, after projected from the upper surface of backlight in the form of area source.Point light
The wavelength in source is blueness, and wavelength can be from 405nm to 455nm.Due to absorption of the quantum dot to blue light, the laser incident from left end
It can deepen with the distance for entering light guide plate, the reduction of feux rouges and green glow caused by quantum dot, then the light ejected is gradual
Form uneven mixed white light.
Side effect may be obtained for reduction is this, makes the light of outgoing uniform, it is special that in the bottom of light guide plate, different densities are set
Scattering point structure, scattering when it act as making scattering light on the right side of light guide plate compared with left end incidence is strong, can so cause from
The uniformity for the light that the special-shaped upper surface of light guide plate 401 is projected is improved.Mixed white light after quantum dot membrane system is by bottom
Reflectance coating 801 reflection, bottom diffusing structure scattering and surrounding reflectance coating reflection, finally from the upper surface of light guide plate
It is emitted in the form of area source.By quantum dot film 802, brightness enhancement film 804, then through even smooth film 806, most afterwards through LCDs
807 outgoing, form uniform area light source.For fixed laser spot light 101, Bao Weier lens 201, special-shaped light guide plate 401, and after
Continuous membrane system, all laser point light sources 101, Bao Weier lens 201, special-shaped light guide plate 401, is all fixed on backboard 701.
Fig. 4 show the special-shaped light guide plate top view of modularization line laser quantum dot backlight module device.It is there it can be seen that different
The structure of shape light guide plate 401 is that its left and right ends is equipped with laser point light source 101 and Bao Weier lens 201, and left and right ends are incident
Face 301 is simultaneous to be provided with anti-reflection film.Can shape because the segment space of laser point light source 101 and Bao Weier lens 201 does not have light, during splicing
Into dark space.To reduce the influence of this respect, using the special-shaped light guide plate 401 of this structure, if as far as possible using small
Laser point light source 101 and Bao Weier lens 201 so that their size accounts for the display area of very little, and most dark space is reduced at last
It is minimum.
Now guide-lighting plate suqare is limited by laser point light source 101 and lens area in the structure, so by quantum dot film
It is that area expands the whole special-shaped light guide plate 401 of covering, dark space can be reduced.
Present invention design is extensible to be applied to other shapes of light guide plate, such as circle, can also be applied to irregular component
Shape back light system designs.
The laser point light source 101 makes one for replaceable and detaching structure, laser point light source and Bao Weier lens 201
Body formula, hot spot optimization is carried out in advance.So that the laser projected is easier to enter light guide plate.Modularization uses replaceable design.
When some Module Fail, the replacement that can make good use of, reduce the maintenance cost of system.
