Description
[technical field]
The present invention relates to field of display technology, more particularly to the preparation method and optical diaphragm of a kind of dyestuff.
[background technique]
With the development of display technology, the colour gamut of display is also constantly being promoted.High colour gamut means that display can be shown
More colourful color is shown, there is stronger color to show ability, occur during display to be effectively prevented from
The case where distortion and color lump.Since the type of color increases, so that the color switching of picture can be more naturally, make in display
The level for obtaining picture is more clearly demarcated, can show more details and closer true effect.
For liquid crystal display, since screen itself does not have spontaneous light attribute, promotes colour gamut and mainly pass through three originals
The color fim filter of color (red, green, blue) is realized；In addition it is also possible to carry out the promotion of colour gamut by the adjustment of backlight, at present
There are two types of the main modes for promoting backlight purity: using the backlight of blue led and red green fluorescence material；Using quantum dot (QD)
Backlight technology.
However, due to not purified to red green blue tricolor light during promoting colour gamut, namely exist dark green
Light and yellow orange light, therefore above two colour gamut method for improving makes the red green blue tricolor light finally issued impure.With
The promotion of colour gamut, penetrating for light also decline therewith, to be difficult to realize realize the promotion of brightness while colour gamut is promoted.
Although being absorbed at present by rhodamine material to the veiling glare except RGB, dye stuff of rhodamine kinds is most
There is an acromion on the left of big absorption peak, the blue and green light of part can be absorbed, since dye stuff of rhodamine kinds is easy to produce reunion,
Cause the influx and translocation of acromion, and green portions directly affect penetrance, so as to cause penetrance decline.
Therefore, it is necessary to the preparation method and optical diaphragm of a kind of dyestuff be provided, to solve to ask present in the prior art
Topic.
