Description
Technical field
The invention belongs to light guide plate technical fields, more particularly to a kind of automobile display screen light guide plate.
Background technology
Recently as various information, communication, the development for consuming liquid crystal display product, especially various Color Liquid Crystal Displays
The development of product requires the briliancy, light-emitting uniformity and light extraction efficiency of light-source system growing day by day.
Generally there are two types of working methods for existing light guide plate, the first provides light by light source, enters light by light guide plate
Face enters in light guide plate, is then projected by the light-emitting surface of light guide plate；It is another then be tool there are two opposite light-emitting surface, light source institute
The light of offer is projected from two light-emitting surfaces respectively after entering light guide plate；In order to enable can be more by the light inside light guide plate
It equably mixes, it will usually which V-arrangement or R shape micro-structures are set on the light-emitting surface of light guide plate；However this structure mini structure is then
It can make that the collection photosensitiveness of light guide plate is too high, directive property is too strong, light extraction also tends to not enough uniformly, and since this micro-structure has point
Angle, this micro-structure can scratch or touch down because being rubbed in transportational process, and then influence the function of light guide plate；For leading
For tabula rasa, the key factor for evaluating its quality is guide-lighting effect and the guide-lighting uniformity, and two factors of decision maker
It is crucial with net-pont design personalized on light guide plate, although has there are some personalized sites in existing light guide plate
Design method, but its light-out effect often also needs to further improve, and for the course of work of light guide plate, due to
Light source will produce heat, and good heat dissipation performance is also very crucial.
Invention content
The purpose of the present invention is to provide a kind of automobile display screen light guide plate, by the Unequal distance of optically focused cylinder and miniature
Concave-convex cambered surfaces structure design solves existing light guide plate light source during diverging, due to the influence of distance, transmission is made to go out
Light continuously decreases, and then the final derived light of light guide plate is made secretly to differ, brighter at light source, is asked far from dark at light source
Topic；By the concave-convex cambered surfaces fillet design on optically focused cylinder, solves existing light guide plate because micro-structure has wedge angle, transporting
It causes micro-structure to scratch because being rubbed in the process to touch down, final the problem of influencing light guide plate function；Not by point reflection group
Equidistant design, the light to shed cannot repeatedly be reflected by solving existing light guide plate, and light is caused not reflected effectively all,
The problem of ray waste is caused to influence final light projector effect；Also solves existing light guide plate light source because distance declines simultaneously
After subtracting, cannot object density effectively be reflected by increase, decaying, the uniform purpose of light projector are offset to reach；Pass through reflection
The design of shell solves the problems, such as that existing light guide plate light source distributes and more disperses；Pass through heat sink, cooling fin, heat dissipating layer
Matching design, solve the problems, such as that existing light guide plate radiating efficiency is low.

The invention has the advantages that：
1, the present invention is designed by the Unequal distance of optically focused cylinder and miniature concave-convex cambered surfaces, makes the light guide plate not by light source distance
Influence of fading achievees the purpose that offset light source decaying, to make final light guide plate lead by gradually increasing the density of optically focused cylinder
The bright evenness higher gone out；By the concave-convex cambered surfaces fillet design on optically focused cylinder, on the one hand can avoid in transportational process
Finally light guide plate function is influenced because being generated to scratch to touch down by friction；On the other hand the reflective surface area of its own is also improved；Pass through
The Unequal distance and size personalized designs of point reflection group enable the light guide plate adequately to be carried out using surrounding dot intensive anti-
It penetrates, avoids the light that light source is sent out that from can not being fully utilized, cause to waste, to influence final effect.
2, the present invention enables the light guide plate efficiently to gather light source by the trapezoidal design of reflection shell；By heat sink,
The matching design of heat dissipating layer and cooling fin keeps the light guide plate radiating efficiency higher and faster.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
