Description
Technical field
The present invention relates to a kind of LED traffic screen, in particular, it is related to a kind of LED traffic display screen colour gamut implementation method.
Background technology
EN12966 standards are the technical parameter standards that European Union sets in field of traffic, in optics aspect, it is necessary to meet C1-
2nd, the optical index such as L1-3, B1-7, R1-3.Our this inventive method is said take off C2 in detail below aiming at C2 standards
Standard：R G B Y five kinds of colors of W be required for meeting C2 standards, in C2 regions.EN12966 standard C2 indexs, it is necessary to R G B
Y five kinds of colors of W will meet, in order to meet the C2 indexs of Y colors, available scheme has two kinds in the industry：1. the special G colors of purchase
LED.Shortcoming：Price, the cycle is long, and quantity is indefinite.2.LED lights, and after PC prisms, XY coordinates have a small amount of skew,
Offset by effectively controlling these, its Y mixture of colours is reached C2 coordinates.
The content of the invention
The technical purpose of the present invention is to overcome in the prior art, and LED traffic display screen realizes technology colour gamut, exists
Colour mixture problem and cause to be difficult to the technical problem for meeting relevant criterion；There is provided a kind of low cost and easy to implement, change prism face
Color and the LED traffic display screen colour gamut implementation methods for controlling colour gamut.
To realize above technical problem, the technical scheme is that：
LED traffic display screen colour gamut implementation methods, methods described includes having the following steps：
Rectangular pyramid structure prism is provided with above a.LED light emitting diodes, the prism is printing opacity PC materials, the printing opacity PC materials
Orange toner containing 0.01%-0.5% ratios in material；
B. the orange toner changes the XY coordinate values that LED light emitting diodes send light source, its light extraction is met C2 standards.
Further, the orange toner containing 0.05%-0.1% ratios in the PC materials；
Further, the orange toner containing 0.075% ratio in the PC materials；
Further, the orange toner containing 0.05%-0.1% ratios in the PC materials；
Y color contaminations color C2 implementation methods of the present invention：A kind of material is added in PC prisms, it can change the XY coordinate positions of G colors,
Again by R after G colour mixtures, its Y color is met C2 coordinate positions, while not influenceing the coordinate value of other four kinds of colors again.This
Invention make it that Y color C2 colour mixtures become easily, and buying in the market common LED, you can meet.The material of this addition is a kind of
It is simple to operate in orange toner, the PC materials added according to 0.05%-0.1% ratio, with stronger actual application value.
The present invention is one and extremely cleverly designed, it is necessary to which the added material of strict control, i.e., can reach colour mixture C2
Purpose, the C2 indexs of other colors can not be changed again.Current this scheme belongs to the world and initiated.
Brief description of the drawings
Fig. 1 is the structural representation of the display mode for optical standard in one embodiment of the invention.
Embodiment
LED traffic display screen colour gamut implementation methods, methods described includes having the following steps：First in LED light emitting diodes
Top is provided with rectangular pyramid structure prism, and the prism is printing opacity PC materials, contains 0.01%-0.5% in the printing opacity PC materials
The orange toner of ratio；The orange toner changes the XY coordinate values that LED light emitting diodes send light source, its light extraction is accorded with
Close C2 standards.In one more preferably embodiment, the orange toner containing 0.05%-0.1% ratios in PC materials；In another embodiment
In, the orange toner containing 0.075% ratio in the PC materials；In another embodiment, 0.1% ratio is contained in the PC materials
Orange toner.Optimal, the orange toner containing 0.06% ratio in the PC materials.
European Union EN12966 standard C2 indexs, it is necessary to R G B Y five kinds of colors of W will meet, color show X, Y coordinate show
Show in C2 regions.Blend of colors, display mode is shown in accompanying drawing 1, there is individual difficult point here, and this difficult point is exactly Y colors.Y colors are by R
Match what is formed with G, if it is desired to meet the C2 regions of Y colors, it is necessary to which special G color chips, two colour mixtures are possible to reach
C2 regions.But the conventional LED of in the market, G colors can not meet demand.Y color contaminations color C2 implementation methods of the present invention：Prism
Made using printing opacity PC materials, a kind of orange toner is added in printing opacity PC materials, is added to according to 0.05%-0.1% ratio
In the printing opacity PC materials for making prism, it can change the XY coordinate positions of G colors, then by R after G colour mixtures, enable its Y color
Meet C2 coordinate positions, while not influenceing the coordinate value of other four kinds of colors again.In force, orange toner can use oiliness color
Essence, mill base or other conventional PC dyeing material agent；Become easily the invention enables Y color C2 colour mixtures, and buying in the market
Common LED, you can meet.It is simple to operate, with stronger actual application value.
