Description
Technical field
The present invention relates to the technical field of display backlight device, a kind of quantum dot optical module, quantum dot are specifically related to
Lens and its manufacture method.
Background technology
Quantum dot has luminescent spectrum adjustable, and FWHM (full width at half maximum, halfwidth, also known as
Half-peak breadth, refers to the overall with of bands of a spectrum when absorption band height maximum is highly half, namely transmission during peak height half
Peak width) narrow, the features such as luminous efficiency is high.But oxygen is afraid of because quantum dot is afraid of water and high to temperature dependency；When quantum dot application
, can be with water proof oxygen barrier and away from LED/light source, it is possible thereby to ensure that quantum dot has good reliability (letter in liquid crystal panel
Lai Xing：The checking of the related functionality carried out by application of the analog equipment under client and actual service conditions is (such as：
Electrically, plug, turn on etc.), finally required so that it is guaranteed that product meets client).
Additionally due to the absorption spectrum and luminosity spectral characteristic of quantum dot are as shown in figure 1, it can be seen from the figure that quantum dot
Absorption spectrum is wider, if two kinds of color (red, green) quantum dots are mixed again together, easily produces double absorption, such as feux rouges and green glow
Quantum dot is mixed, and easily occurs the phenomenon that red light quantum point absorbs green glow, so as to cause luminous efficiency to decline.
In addition, at present in RGB three-color light-emitting systems, cyan light is not bright-coloured enough, it is impossible to real-world object color color is completely covered
How domain scope, expeditiously realize that the liquid crystal display that real-world object color can be completely covered turns into the research of liquid crystal display
Direction.In the past, people, which have, to be studied using the white light backlight with cyan spectrum and with the color colors of RGBC (cyan Cyan) four
Real-world object color is completely covered to attempt realization in the liquid crystal panel of optical filtering, but from the point of view of related research, cyan light spectrum plus
Enter, can cause to be mixed into part cyan in the colors of RGB tri-, so that the excitation of the colors of RGB tri- is reduced, the bright-colored degree of the colors of RGB tri-
Decline on the contrary, and due to the addition of cyan color blocking, just may require that the transmittance spectrum of blueness and green is narrower, this is accomplished by color blocking
Thickness further thickeies or concentration further increases, so that the yield reduction and penetrance decline of color blocking procedure for producing can be produced
