Color, excitation is poor, and color gamut value is low, and more light loss be present.
Light-emitting phosphor material is widely used in LED, but the light decay of fluorescent material is big, granulation uniformity is poor, service life is short.
Quantum dot (QD) luminous efficiency is high, and optical purity is very high, and substituting fluorescent material with QD can greatly improve luminous efficiency, extends and uses
Life-span.Using blue light as the backlight of display screen, excite QD powder to obtain red, green glow, form three primary colours, can largely carry
Colour gamut is risen, makes color distincter, the color of access expansion spectrum can be generated, application prospect is had an optimistic view of.
The content of the invention
It is an object of the invention to provide a kind of blue light TFT-LCD display screen method for packing efficiently, inexpensive, the display screen
Colored filter is substituted with the film layer that envelope has red and green QD powder, conventional white light is substituted as backlight using blue light, passes through TFT
Liquid crystal arrangement is controlled, and then shows multicolour pattern.
The object of the present invention is achieved like this：This method mainly includes QD film layers processing procedure, TFT ARRAY processing procedures and combination
Process, QD film layer processing procedures are：The groove of rule arrangement is carved on the transparent substrate, and red and green QD powder is poured in corresponding groove
In, red and a green are set without grooved belt between being one group, every group, completely cut off the transparent membrane of air by QD with waterproof
It is enclosed in formation QD film layers between functional membrane and substrate；TFT ARRAY processing procedures include cleaning, plated film, etching, and it is brilliant to form thin-film electro
Liquid crystal is enclosed between double-layer structure by body, anabolic process for double-layer structure is cut by required size；It is indigo plant in backlight
Under the irradiation of light, the transit dose of the tropism control blue light of liquid crystal is controlled by TFT；The blue light of transmission excites the correspondence in QD film layers
QD powder in the primitive of position, sends green light and red light；Red, green light forms one with the blue light appeared without grooved belt
Primitive, and then form coloured image.
The invention specific implementation method is：
1.QD film layer processing procedures：By transparency carrier or film（Sapphire, glass, acrylic etc.）Cleaned and dried；By follow-up
Module packaging arrangement requires to carve the groove of rule on transparency carrier or film；Being irrigated in corresponding groove can send through blue light illumination
The QD powder of feux rouges or gold-tinted（QD, which is powder, is scattered in form in ink or in light-sensitive emulsion is present）；In transparency carrier or film
The transparent membrane of upper deposition waterproof isolation air（The single or multiple lift composite membrane such as polyurethane, epoxy resin, Parylene）.
2.TFT layer processing procedures：Using traditional TFT ARRAY processing procedures, through being cleaned multiple times, plated film, etching, membrane transistor is formed.
3. double-layer structure is cut by required size, and liquid crystal is enclosed between double-layer structure.
4. in backlight（Blue light）Irradiation under, controlled by TFT, excite the QD in the correspondence position primitive in QD film layers
Powder, send green light and red light.Red, green light forms a primitive with the blue light appeared without grooved belt, and then is formed
Coloured image.
The beneficial effects of the invention are as follows：1）Utilize the quantum dot film layer of red, green QD powder combination room composition three primary colours primitive
Combined with TFT layer, substitute conventional white light backlight with reference to blue light backlight and colored filter realizes the display of coloured image, can
Light loss is effectively reduced, and improves display screen colour gamut, makes color distincter；2）Quantum dot is enclosed in transparent functional film layer
Between base film layer, make QD completely isolated with external environment, QD can be avoided to be contacted with air and water；3）Directly by quantum
Press certain arrangement form perfusion and membrane structure is made, can flexibly be cut as needed, or even directly mount, improve envelope
Fill efficiency； 4）It is simple using processing procedure manufacture display screen technical process, packaging efficiency and yield can be greatly improved, reduces production
Cost, extend display screen service life.
