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 sheet-like back light source with high dispersion effect, including glue frame 1, be placed in glue frame 1
Reflectance coating 2, light guide plate 3, blooming piece, light source 10, shading glue 7 and FPC wiring boards 9, light source 10 can be LED/light source, light source
10 are fixedly welded on FPC wiring boards, therewith constitute fluid welding semi-finished product (FPC+ light sources), FPC wiring boards 9 can be by double
Face glue 8 is fixed in glue frame；Blooming piece includes diffusion barrier 4 and bright enhancement film, and the exiting surface of light guide plate 3 is provided with point-like projection 16,
And if light guide plate 3 is placed with dry nebulization point 13 positioned at the light outlets position of light source 10, the side that light guide plate 3 is connected with glue frame 1 is formed
By reflectance coating towards glue frame top droop hypotenuse 17.
Point-like projection 16 can be directly injection-moulded in the exiting surface of light guide plate by way of injection molding, and light is played very well
Scattering process, the side of light guide plate is attached in glue frame, or neck is set in glue frame, and light guide plate side sets bayonet socket, passed through
Bayonet socket coordinates with neck carries out clamp.Because light guide plate is arranged the thin and close some of certain zonule in light source luminescent mouthful position
Point is atomized, the light of light source luminescent mouthful is diffused, plays a part of scattering, light source luminescent mouthful hot spot can be effectively eliminated,
The visual effect reached.Atomization point can be processed by laser process technology to be formed, during specific arrangement design, mist
It is equidistant arrangement, dense arrangement to change point 13.In order to not influence backlight luminescence brightness, atomization point need to be small and shallow, in processing, laser
Energy, which is adjusted, must be significantly smaller than conventional point energy.The inclination angle of hypotenuse 17 is 10 ° to 15 ° so that have what reflectance coating was reflected
Light will be moved to the vertical direction of light guide plate so that narrower shading glue can hide the light gone out from light guide plate offside reflection
Firmly, it is to avoid backlight side forms bright line.
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.Certainly, according to reality
The need for border, diffusion barrier is it can also be provided that two layers, and two layers of bright enhancement film is between two layers of diffusion barrier.Shading glue is black two-sided
Shading glue, glue frame passes through black two-sided shading glue sticking with liquid crystal display.Reflectance coating 2 is provided with cutting line in light source close region.By
High temperature is also easy to produce near LED/light source to cause the warpage of reflectance coating, causes liquid crystal panel display uneven, to overcome because of high temperature
The reflection warpage of generation is bad, by the setting of cutting line, is cut off for reflectance coating in the region of different temperatures, it is to avoid anti-
Penetrate the heated uneven striction phenomenon produced of film.
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.
In addition, setting the light being placed with hollow layer, hollow layer for light source to be sent to be oriented to light guide plate in light guide plate 3
3 exiting surfaces and can limited support hollow layer upper and lower end face reflective support mechanism, reflective support mechanism include multiple support protrusions
11 and the atomizing particle 12 located at the inwall of support protrusion 11；Atomizing particle 12 is passed through using the transparent grain with high reflectance
After light source irradiation, it reflexes to leaded light from all angles enter light guide plate from all angles by the light that light source is sent
The exiting surface of plate, the light that non-face light source can so produced reaches the effect of area source, takes into account light source power consumption and generation
The effect of uniform light, support protrusion and atomizing particle are arranged inside light guide plate, while playing a supporting role, reached
Above-mentioned area source effect and the effect for producing uniform light, atomizing particle are arranged in the cavity of relative closure, it is to avoid entered miscellaneous
Matter and influence light effects.Support protrusion 11 can be waveform, triangle or mountain ridge-like structure.The positive drift angle of light guide plate 3
Place is provided with the positioning convex 14 for coordinating fixed blooming piece.Blooming piece is provided with the breach knot coordinated with positioning convex 14
Structure, is fixed on light guide plate by the cooperation with positioning convex, is prevented effectively from blooming piece displacement.
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.
In order to increase reflectivity, the circumferential side wall of light guide plate 3 is coated with white inverse framework 21, by increasing in four the week side of boss walls
If white reflective framework, reflectivity is greatly improved.
The utility model is exemplarily described above in association with accompanying drawing.Obviously, the utility model is implemented not
Limited by aforesaid way.As long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or it is not improved, above-mentioned design of the present utility model and technical scheme are directly applied into other occasions, at this
Within the protection domain of utility model.
