Description
Technical field
The present invention relates to a kind of process, in particular, it is related to a kind of high colour gamut display backlight process.
Background technology
Mobile phone, flat panel backlight are the essential components of mobile phone, panel display screen, and the sector generally uses 010 or 020
LED.The high colour gamut of display screen requires that color gamut value professional standard reaches more than 90%, but common LED backlit display colour gamut
Value 63%-75%;Common LED strengthens filtering technique using colour gamut(The technology of South Korea, filter out gold-tinted and veiling glare)Display screen
Color gamut value can reach 72%-85%;LED is blue luminescence chip, typically also needs to further be mixed colours with fluorescent material.
Usual LED is to carry out light modulation toning using blue luminescence chip and yellow or orange fluorescent powder, but colour gamut strengthens filterer
Skill causes the low color gamut value of brightness of display screen low because that can filter the light of yellow.It can reach that high colour gamut requirement only has in the market
OLED and RGBLED techniques, but OLED technique manufacturing costs are very high, manufacturing process difficulty is big.RGBLED can not ensure large quantities of
The uniformity of amount, it is impracticable.And the very low easy colour cast of mode color gamut value mixed colours using common led, strengthened by colour gamut and filtered
Technique does not reach the requirement of high colour gamut still.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of high colour gamut display backlight technique side
Method.
To achieve the above object, the invention provides following technical scheme:A kind of technique side of high colour gamut display backlight
Method, it is characterised in that:Comprise the following steps,
S1:Add green emitting phosphor allotment encapsulation in LED lamp bead blue luminescence chip and red fluorescence powder;
S2:By glue, green emitting phosphor, red fluorescence powder 67.7%-80% in proportion:19%-30%:0.9%-2.3% ratio is entered
Row allotment;
S3:The light inspired by the LED after toning is subjected to enhancing feux rouges, blue and green light colour gamut PROCESS FOR TREATMENT, Huang is filtered
Light, veiling glare;
S4:Last light is subjected to color proportioning, enhancing feux rouges, blue and green light colour gamut filtering veiling glare obtain the light of high colour gamut
Line.
The obtained light of the present invention, its LED X values are 0.241-0.31, and Y value is 0.235-0.31, and color temperature value is
6000-11000K;It is common to adjust the XY values reached to be 0.28-0.295 with yellow fluorescent material, but most preferably 0.288-0.2873.
Preferably, the glue quantity in S2 steps:Red fluorescence powder consumption:The ratio between green emitting phosphor consumption is 70%-75%
:24%-28%:1%-2%.
Preferably, in S3 steps enhancing feux rouges, blue and green light colour gamut technique are that colour gamut strengthens filtering technique.
Preferably, the obtained light color gamut value in S4 steps is 90%-115%.
Present invention tool has the advantage that:Such a technique of the present invention can reach 90%-115% color gamut value, meet display screen line
The requirement of the high color gamut value of industry, but it is more much lower than display screen industry OLED and RGB LED high colour gamut cost and also enhance
Protect eyes function, colour gamut enhancing filtering process technique can realize on the upper and lower bright enhancement film of diffusion barrier, on upper bright enhancement film, up and down
Add lustre on composite membrane including in the down polaroid of display screen, colour gamut enhancing filtering process technique can also be separately made individual color
Domain enhancing filter membrane is used, such as be clipped between diffusion barrier and lower bright enhancement film, between lower bright enhancement film and upper bright enhancement film or
Above upper bright enhancement film.
