Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to it to implement.
As shown in Figures 1 to 4, a kind of Novel backlight, including glue frame 1, the reflectance coating 2 being placed in glue frame 1, light guide plate 3,
Blooming piece, shading glue, light source 10 and FPC wiring boards 9, light source 10 are fixedly welded on FPC wiring boards, therewith constitute stream
Semi-finished product (FPC+ light sources) are welded, FPC wiring boards 9 can be fixed in glue frame by double faced adhesive tape 8, blooming piece includes diffusion barrier 4
And bright enhancement film；Side that light guide plate 3 is connected with glue frame 1 is formed by reflectance coating 2 towards the hypotenuse 17 of the top droop of glue frame 1, hypotenuse 17
Surface be provided with black strip piece 20, if light guide plate 3 is placed with dry nebulization point 13 positioned at the light outlets position of light source 10.Light source can be with
Light source is used as using LED.Blooming piece be provided with positioning convex 14 coordinate gap structure, by with positioning convex
Cooperation is fixed on light guide plate, is prevented effectively from blooming piece displacement.
The inclination angle of hypotenuse is 10 ° to 15 ° so that have the light that reflectance coating is reflected by the vertical direction of light guide plate
It is mobile so that narrower shading glue can cover the light gone out from light guide plate offside reflection, it is to avoid backlight side forms bright
Line.Black strip piece 20 avoids light from never needing to the position light extraction of light extraction, causes undesirable optics bad, such as lamp
Mouth hot spot etc..It is preferred that, the length of black strip piece is identical with the width of light guide plate, effectively prevent it is bad go out optical issue, black
Strip piece can be attached to the surface of hypotenuse by way of stickup.Black strip piece and glue frame, the sealing space of reflectance coating formation
Flexible heat conductive silica gel is inside preferably filled, on the one hand can be for heat conduction, on the other hand with the effect for preventing from rocking.Due to leading
The thin and close dry nebulization point of certain zonule if tabula rasa is arranged in light source luminescent mouthful position, is carried out to the light of light source luminescent mouthful
Diffusion, plays a part of scattering, can effectively eliminate light source luminescent mouthful hot spot, the visual effect reached.Atomization point compact district
Domain with above-mentioned support protrusion is preferably corresponding is configured, by both mating reactions, the light derived from light guide plate exiting surface
Line is uniformly high, and without hot spot, with more preferable visual effect.Atomization point can be processed by laser process technology and
Into during specific arrangement design, atomization point 13 is equidistant arrangement, dense arrangement.In order to not influence backlight luminescence brightness, point is atomized
Need to be small and shallow, in processing, laser energy, which is adjusted, must be significantly smaller than conventional point energy.

Reflectance coating 2 is provided with cutting line in light source close region.Due to being also easy to produce high temperature near LED/light source so as to cause reflection
The warpage of film, causes liquid crystal panel display uneven, to overcome because the reflection warpage of high temperature generation is bad, passes through setting for cutting line
Put, cut off for reflectance coating in the region of different temperatures, it is to avoid the heated uneven striction phenomenon produced of reflectance coating.
Diffusion barrier 4 is one layer, and bright enhancement film is two layers, respectively the first bright enhancement film 5 and the second bright enhancement film 6, two layers of bright enhancement film
On diffusion barrier 4.Shading glue uses black shading glue.It is from top to bottom black successively that the erection sequence of specific each part, which is,
Black shading glue 7, the second bright enhancement film 6, the first bright enhancement film 5, diffusion barrier 4, light guide plate 3, reflectance coating 2 and glue frame 1.During specific assembling,
The second bright enhancement film 6, the first bright enhancement film 5, the combination of diffusion barrier 4 are attached on light guide plate successively, then covered shading glue 7 most upper
Layer, is bonded above glue frame, compresses.For the ease of the second bright enhancement film, the first bright enhancement film, diffusion barrier location and installation on light guide plate,
The side of second bright enhancement film, the first bright enhancement film and diffusion barrier is respectively provided with limited bayonet, and the side of light guide plate 3 sets neck, passed through
Limited bayonet coordinates with neck carries out positioning clamp.Shading glue can use black double faced adhesive tape, on the one hand for shading, the opposing party
Face is used for pasting liquid crystal display.Liquid crystal display is fixed with glue frame by black shading glue.
The circumferential side wall of light guide plate is coated with white reflective framework, by setting up white reflective framework in four the week side of boss walls, instead
The rate of penetrating is greatly improved.
In order to increase structural strength, the backlight also includes chase, and chase and glue frame are preferably integrated formed structure.It can use
Injection machine passes through injection mold injection moulding integrated molding.In addition, chase also has the effect of protection and shielding.
In addition, the light being placed with hollow layer, hollow layer for light source to be sent can be set to lead in light guide plate 3
Tabula rasa exiting surface and can limited support hollow layer upper and lower end face reflective support mechanism, reflective support mechanism include it is multiple support it is convex
Play 11 and the atomizing particle 12 located at the inwall of support protrusion 11；Provided with the fixed blooming piece of cooperation at the positive drift angle of light guide plate 3
Positioning convex 14.Atomizing particle 12 is using the transparent grain with high reflectance, after light source irradiates, and it is from all angles
Into in light guide plate, and then the light that light source is sent is reflexed to from all angles the exiting surface of light guide plate, can so made non-
The light that area source is produced reaches the effect of area source, takes into account light source power consumption and produces the effect of uniform light, will support convex
Rise and be arranged at atomizing particle inside light guide plate, while playing a supporting role, reach above-mentioned area source effect and produce equal
The effect of even light, atomizing particle is arranged in the cavity of relative closure, it is to avoid is entered impurity and is influenceed light effects.Support is convex
It can be waveform, triangle or mountain ridge-like structure to play 11.
