Description
Technical field
This utility model relates to technical field of liquid crystal display, is specifically related to a kind of quantum dot displays keeping low temperature.
Background technology
Quantum dot (quantum dot) is the nano material of quasi-zero dimension (quasi-zero-dimensional), is made up of a small amount of atom.Roughly, the size of three dimensions of quantum dot is all in 100 nanometers (nm) below, outward appearance is all limited to just like a minimum pointing object, the motion in all directions of its internal electron, so quantum confined effect (quantum confinement effect) is particularly significant.
The colour gamut of LCD TV depends on the matching degree of the spectral characteristic of backlight and spectrum and liquid crystal panel colored filter (CF).As long as back light white light, white light can be obtained by any color wanted through optical filter again, if the enough height of white light colour gamut, the LCD TV colour gamut drawn also can be high.Industry commonly used NTSC standard weighs color rendering effect at present, and color domain coverage ratio (abbreviation colour gamut) is the highest, and the color gamut that TV is presented is the abundantest, closer to Natural color.
Traditional WLED TV mostly use " blue-ray LED+yellow fluorescent powder " light-emitting mode (light sent by blue-ray LED excite yellow fluorescent powder produce gold-tinted, remaining blue light and gold-tinted colour mixture and obtain white light, for RGB three primary colours, its excitation is very poor), though people can be allowed to feel white light, but lack HONGGUANG and green glow makes colour mixture the most difficult, be to cause the reason that color domain coverage ratio is on the low side and backlight conversion efficiency is the highest.General color domain coverage ratio (abbreviation colour gamut) is less than 72%, and current most of liquid crystal displays (TV or mobile phone) all use this light-emitting mode.
In prior art, use the technology main flow of quantum dot light emitting, it is mainly that the light utilizing blue-ray LED to send excites two amounts sub-point (red light quantum point and green light quantum point) material, send HONGGUANG and green glow respectively, and becoming white light with remaining blue light colour mixture, this white light is just as the back light of LCD TV.This white light colour gamut out can reach 110%, and colour gamut and the efficiency of quantum dot liquid crystal display are higher, so its picture color is more natural beautiful, and take into account energy-conserving and environment-protective.
But the cost of quantum dot is the highest at present, and quantum dot can be because there is certain unstability in the environmental factorss such as temperature height, the shortcoming of poor stability, the equipment such as performance most notably current electronic equipment especially mobile phone, in use there may be certain hot environment, the illuminating source of such quantum dot then extremely unstable.
