Description
Technical field
The present invention relates to demonstration module backlight field, be specifically related to quantum dot optics coating composition, reach fluorescent optics diaphragm prepared by this optical coating composition of application, this blooming piece can be used to significantly widen the colour gamut range that available liquid crystal shows.
Background technology
Liquid crystal indicator mainly is comprised of liquid crystal panel and backlight module two parts.Liquid crystal panel itself is not luminous, need be by the light of backlight module generation.Be widely used at present light source in backlight module and mainly contain two kinds of CCFL (cold cathodefluorescent lamp, CCFL) and photodiodes (light emitting diode, LED).Although the light that CCFL sends has good colorimetric purity, the common more general white light emitting diode of the performance aspect color is better.But in CCFL, contain mercury, not only cost is high and large to environmental hazard, from the angle of environmental protection, it will be a corollary that LED substitutes CCFL gradually.The LED power saving, energy-conservation, the life-span is long, and volume is little and light direction is good, can significantly reduce the thickness of light guiding plate in the traditional backlight source, even can be without light guiding plate.
But the demonstration colour gamut of LED-backlit source indicating meter is generally on the low side at present, for the NTSC standard, (be only under National Television System Committee's specified standards, the summation of the color that technological system can produce, represented that indicating meter can Show Color enriches the ability of degree) 60% left and right.This is because liquid crystal panel itself is not luminous, need to rely on the white light that send in the LED-backlit source just can be embodied as picture after color filter film, so in the white light that sends of backlight, the spectral shape (being trichromatic spectral wavelength position, spectrum peak width at half height, ratio) of Red Green Blue will directly have influence on the last color effect of indicating meter.Widely used backlight excites yellow rare-earth fluorescent powder to obtain white light by blue led in the indicating meter of LED-backlit source at present, and in this white light, the spectral shape of Red Green Blue is poor.Although the LED that finds out by the red bluish-green three kinds of colors of direct use of manufacturers was used as backlight afterwards, due to the purity of color higher (being spectrum half-peak width) of LED, rationally mix photochromic after, can realize being greater than the colour gamut performance of 100%NTSC standard.But, owing to using red bluish-green three-color LED to bring high cost, make the market acceptance of this technological line extremely low.
The present invention is in order to make up the deficiencies in the prior art, adopt the accurate coating technique of blooming, a kind of fluorescent optics diaphragm is provided, it mainly forms the components such as quantum dot, film forming material to mix formation optical coating composition according to distinctive formula, then said composition is coated on transparent film base material or blooming and forms the fluorescent optics film.With traditional fluorescent material, compare, the characteristics that quanta point material has are: 1) quantum dot is a kind of nano semiconductor material particle, and its physical diameter is less than or near the exciton Bohr radius; The advantages such as 2) due to quantum size effect, it is wide that this material has excitation wavelength range, and emission peak is narrow and be Gaussian symmetric, nothing hangover, Stokes shift is large, photochemical stability is strong; 3) when being subject to the exciting of ultraviolet or blue light source, quantum dot just can send the fluorescence excitation of peculiar wavelength, and the fluorescence spectrum of quantum dot emission is determined by chemical constitution and its size of quantum dot.The optical coating composition of development according to the present invention, form and be thick with the numerous quanta point material that only has several nanosizeds on the fluorescent optics film, these quanta point materials, under the exciting of blue-ray LED, can send redness or green fluorescence.This nanocrystalline blooming has not only been realized the effect of back light diffusion, has also changed the spectrum composition of light source simultaneously.Adopt the display device of this fluorescent screen substantially can reach the demonstration colour gamut of 100%NTSC, and cost is reasonable.
