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 5, a kind of novel plate shaped backlight, including glue frame 1, the reflectance coating 2 being placed in glue frame 1, leaded light
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 structure
Into fluid welding semi-finished product (FPC+ light sources), FPC wiring boards 9 can be fixed in glue frame by double faced adhesive tape 8, and blooming piece includes diffusion
Film 4 and bright enhancement film；The light being placed with hollow layer, hollow layer for light source to be sent is set to be oriented to light guide plate in light guide plate 3
Exiting surface and can limited support hollow layer upper and lower end face reflective support mechanism, reflective support mechanism include multiple support protrusions 11
With the atomizing particle 12 located at the inwall of support protrusion 11；Determining provided with the fixed blooming piece of cooperation at the positive drift angle of light guide plate 3
Position projection 14.Atomizing particle 12 is using the transparent grain with high reflectance, after light source irradiates, and it enters from all angles
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 make non-face light
The light that source is produced reaches the effect of area source, takes into account light source power consumption and produces the effect of uniform light, by support protrusion with
Atomizing particle is arranged inside light guide plate, while playing a supporting role, and is reached above-mentioned area source effect and is produced uniform light
The effect of line, atomizing particle is arranged in the cavity of relative closure, it is to avoid is entered impurity and is influenceed light effects.Support protrusion 11
Can be waveform, triangle or mountain ridge-like structure.Light source can be used as light source using LED.Blooming piece be provided with
The gap structure that positioning convex 14 coordinates, is fixed on light guide plate by the cooperation with positioning convex, is prevented effectively from blooming piece
Displacement.
If light guide plate 3 is placed with dry nebulization point 13 positioned at the light outlets position of light source 10.Because light guide plate is in light source luminescent mouthful
The thin and close dry nebulization point of certain zonule if position is arranged, is diffused to the light of light source luminescent mouthful, plays scattering
Effect, can effectively eliminate light source luminescent mouthful hot spot, the visual effect reached.Atomization point close quarters and above-mentioned support are convex
Rise preferably to correspond to and be configured, by both mating reactions, uniform light is high derived from light guide plate exiting surface, and unglazed
Spot, with more preferable visual effect.Atomization point can be processed by laser process technology to be formed, specific arrangement design
When, atomization point 13 is equidistant arrangement, dense arrangement.In order to not influence backlight luminescence brightness, atomization point need to be small and shallow, in processing
When, laser energy, which is adjusted, must be significantly smaller than conventional point energy.
Reflectance coating 2 can be structure as a whole with light guide plate 3, specifically can electroplate one layer by the lower surface in light guide plate 3
Argenteous reflectance coating, relative to existing structure, eliminates reflector plate and adhesive layer, effectively reduces backlight integral thickness.
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, and two layers of bright enhancement film is located at expansion
Dissipate on film 4.Shading glue uses black shading glue.The erection sequence of specific each part is is shading glue 7, the successively from top to bottom
Two bright enhancement films 6, the first bright enhancement film 5, diffusion barrier 4, light guide plate 3, reflectance coating 2 and glue frame 1.
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.Certainly, glue frame 1, iron
Frame and light guide plate 3 can also together with set and be structure as a whole.Specifically can by glue frame, chase and light guide plate integrated injection molding into
Type, makes more compact structure, and intensity is more excellent.
The exiting surface of light guide plate 3 is provided with point-like projection 16, and the side that light guide plate 3 is connected with glue frame 1 is formed by the court of reflectance coating 2
The hypotenuse 17 of the top droop of glue frame 1.Point-like projection can be directly injection-moulded in the exiting surface of light guide plate by way of injection molding,
Good scattering process is played to light.The side of light guide plate is attached in glue frame, or neck is set in glue frame, and light guide plate side is set
Bayonet socket is put, is coordinated by bayonet socket and neck and carries out clamp.The inclination angle of hypotenuse is 10 ° to 15 ° so that have reflectance coating to reflect
Light will to light guide plate vertical direction move so that the light that narrower shading glue will can go out from light guide plate offside reflection
Cover, it is to avoid backlight side forms bright line.
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.
The surface of hypotenuse 17 is provided with black strip piece 20, it is to avoid light never needs to the position light extraction of light extraction, causes not wish
Hope that the optics occurred is bad, such as socket hot spot etc..It is preferred that, the length of black strip piece is identical with the width of light guide plate, has
Effect 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
Flexible heat conductive silica gel is preferably filled in frame, the sealing space of reflectance coating formation, on the one hand can be for heat conduction, the opposing party's mask
Prevent from rocking.
The circumferential side wall of light guide plate 3 is coated with white inverse framework 21, by setting up white reflective framework in four the week side of boss walls,
Reflectivity is greatly improved.Gap filling heat conductive silica gel between white reflective framework and FPC wiring boards.By filling heat conductive silica gel
The speed of heat conduction can be accelerated, so as to improve the service life of backlight.
