Description
Technical field
The present invention relates to a kind of light guide plates, and in particular to a kind of light guide plate of glass substrate.
Background technology
The principle of light guide plate is to destroy the complete of LED light source light using site (ink site, hot pressing site, injection molding site)
Reflection is realized that LED becomes the purpose of area source from linear light source, is provided for display luminous to allow light to be come out from light guide plate
Source.But the substrate of traditional light guide plate is affected usually using PMMA materials by humiture, becomes large-sized so working as, is thick
When spending thinning, traditional PMMA light guide plates cannot be satisfied design needs, leading using glass material as substrate then occurs
Tabula rasa.The light guide plate of glass substrate is influenced smaller by humiture, can meet thinner, larger-sized requirement.But
Site is set on glass substrate, if according to traditional net-pont design mode, as shown in Figure 1, the hexagonal regular cloth of site unit
Point is all regular due to the angle arranged regardless of net-pont design, so be easy to causeing interference.In addition, in order to which equilibrium is leaned on
Nearly incident side and the brightness close to light emission side, the site cellar area close to incident side is smaller, as shown in 1A in Fig. 1；Close to go out
The site cellar area of light side is larger, as shown in 1B in Fig. 1.The different site unit of usable floor area on same light guide plate is easy
There is the visual problem in site.
Invention content
The technical problem to be solved in the present invention is to provide a kind of light guide plates not easily causing interference fringe.
In order to solve the above technical problems, a kind of light guide plate of the present invention, including substrate, the substrate surface are equipped with site,
The site includes the site unit of multiple random arrangements.
A specific implementation mode as the present invention, wherein any one of site unit other institutes adjacent thereto
It is not all equal to state the distance between site unit.
A specific implementation mode as the present invention, wherein the line of arbitrary six adjacent site units is not constituted just
Hexagon.
A specific implementation mode as the present invention, wherein the area equation of the site unit.
A specific implementation mode as the present invention, wherein the shape of the site unit is identical.
A specific implementation mode as the present invention, wherein the site unit is the equal circle of diameter.
A specific implementation mode as the present invention, wherein a diameter of 0.15mm~0.45mm of the site unit.
A specific implementation mode as the present invention, wherein the light guide plate includes incident side and light emission side, close to described
The density of the site unit of incident side is less than the density of the site unit close to the light emission side, wherein the site
The density of unit refers to the quantity of the site unit on unit area.
A specific implementation mode as the present invention, wherein the density of the site unit is from the incident side to described
Light emission side gradually increases.
A specific implementation mode as the present invention, wherein the substrate is glass.
The advantageous effect that the present invention can reach is light guide plate mesh point reasonable design of the invention, and picture is uniform；Due to net
Dot element it is in the same size, be less prone to the visual problem of site；Again due to the irregular arrangement of site unit, make light guide plate not
Easily cause interference fringe.

Close to the lattice point structure of light emission side.
Fig. 2 is the light guide plate mesh point structural schematic diagram of one embodiment of the invention, and wherein 2A is proximate to the site knot of incident side
Structure, 2B are proximate to the lattice point structure of light emission side.
Fig. 3 is the arrangement schematic diagram of the site unit of the light guide plate of one embodiment of the invention.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail, but not as a limitation of the invention.
Embodiment 1
As shown in Fig. 2, a kind of light guide plate of the present embodiment, including substrate, the substrate has first surface and with described the
The first surface of the opposite second surface in one surface, the substrate is equipped with the first site, and first site includes multiple random
The site unit then arranged.In the present embodiment, any one of site unit other described site units adjacent thereto
The distance between it is not all equal.Specifically, the site unit 10 centered on any one site unit, around be distributed with it is several its
His site unit, as shown in figure 3, other site units include at least the first site unit 11, the second site unit 12, third net
Dot element 13, the 4th site unit 14, the 5th site unit 16 and the 6th site unit 17, wherein the first site unit 11 with
The distance between central network dot element 10 is X1, and the distance between the second site unit 12 and central network dot element 10 are
X2, and so on, third site unit 13, the 4th site unit 14, the 5th site unit 16, the 6th site unit
The distance between 17 and central network dot element 10 are respectively X3, X4, X5 and X6.X1, X2, X3, X4, X5 and X6 are not all equal.
That is the line of arbitrary six adjacent site units does not constitute regular hexagon.Further, X1, X2, X3, X4, X5 and X6
It is complete unequal.In the present embodiment, the shape of the area equation of all site units, all site units is identical.
Further, all site units are the equal circle of diameter, and circular a diameter of 0.15mm~0.45mm.At this
In embodiment, the light guide plate includes incident side and light emission side, and the density close to the site unit of the incident side is less than
Close to the density of the site unit of the light emission side, wherein the density of the site unit refer on unit area it is described
The quantity of site unit.Specifically, as shown in Fig. 2, the density of the site unit from the incident side to the light emission side by
It is cumulative big.In the present embodiment, the substrate is glass material.
Embodiment 2
The present embodiment provides a kind of light guide plate of two-sided site, the difference with embodiment 1 is that the second surface of substrate is also set
There is the second site, second site includes the site unit of multiple random arrangements, and the site unit of the second site is close
Degree is a constant, no matter i.e. the second site is also proximate to light emission side close to incident side, the density of site unit is constant.In this reality
It applies in example, the density of the site unit of the second site is 1/mm2~3/mm2, the site unit of the second site is configured to area
Equal circle, circular a diameter of 0.15mm~0.35mm.In the present embodiment, the first surface is the light guide plate
Incidence surface, the second surface be the light guide plate light-emitting surface.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification should all belong to the covering scope of the present invention.
