Description
Technical field
The present invention relates to Material Field, be particularly used for modulated light source spectrum, increasing in display field
The wide composite optical material showing colour gamut.
Background technology
From the late period nineties 20th century, color display has had more and more wider in daily life
General and important application, including TV, desktop computer, notebook computer, panel computer, mobile phone etc.
Deng.To about 2010, the smart mobile phone with color display occupied greatly in the life of people
The amount time.The food, shelter of people, row, work and exchange between men, depend on the most greatly
Rely and from color display, obtain information by vision.And kinds of displays people especially amusement is important
One of instrument.It is contemplated that, in the near future, the aggregate demand of display is had lasting by the mankind
Promote.
The display visual effect of display is mainly by temporal resolution, spatial resolution and color-resolution
Determine.The highest temporal resolution provides smooth picture, higher spatial resolution to provide clear
Clear image quality, higher color-resolution then makes picture more natural, more bright-coloured.
Color-resolution shown by display depends primarily on the color of the sent light of display light source and becomes
Divide and purity.Existing main flow color display be liquid crystal display (LCD) or active array organic
Light emitting diode indicator (AMOLED).Wherein liquid crystal display mainly uses white light emitting diode
(WLED) as light source.This type of light source is low due to red, green, blue three primary colours color purity, causes institute's energy
The color of display is confined to narrower colour gamut, is only capable of reaching NTSC's standard color gamut
About 70%.Therefore, the relatively original objects of the picture color shown by this class display is dim, distortion.
Meanwhile, the luminescent substance of displayer is organic electroluminescent dyestuff, and this type of dyestuff exists
Under coherent condition, glow peak is wider, and color purity is low, causes this type of display color gamut to be only about 85%.
Expand the colour gamut of color flat panel display the most at low cost, make colour gamut augmentation to 100%NTSC or with
On, it is that current one researches and develops focus.
Chinese patent CN1221625C describes one " selective absorption material ".This material " is inhaled
Receive the middle light outside the light and three kinds of mass-tones reflected in display, thus strengthen color purity and contrast.”
But inventors herein have recognized that, this kind of method maximum has a problem in that and sponges in display light source
Light, causes display brightness substantially to reduce, and appreciation effect is substantially deteriorated.
" liquid crystal display terminal colour gamut promotes to disclose one in Chinese patent application CN105467674A
Method ".This method " filters in visible light wave range the visible of excessive wave band in addition to three primary colours wave band
Optical spectrum energy, promotes the visible ray purity of this three primary colours wave band ".Inventors herein have recognized that, this
The method of kind has the part light in display light source to be " filtered " equally, and causes display brightness bright
Aobvious reduction, the shortcoming that appreciation effect is substantially deteriorated.
Therefore, inventors herein have recognized that, the method for current existing lifting display terminal colour gamut and
Material all can bring the reduction of display brightness, affects display effect.
Green and red fluorescence powder is added additionally, the illumination mode of LED is blue-light-emitting chip, or blue
Luminescence chip adds yellow fluorescent powder, i.e. all base lights of LED are blue light, its in three primary colours
His two primary colours are required to be converted by fluorescent material obtain.At present, the efficiency of conversion is often at 80%-90
%, i.e. in the luminescence process of LED, the luminous loss inherently existed.
The colour temperature of existing display terminal typically at about 6000-8000K, but, present inventor
Finding, actually high color temperature might not represent high-performance, for the visual perception of human body, suitable
Often bring the softest more natural display effect when reducing colour temperature, reduce what colour temperature was used at present
Generally mode is to increase the content of fluorescent material, but this mode will also tend to bring the increase of loss.
