Or photon excitation, thus produce the photon of band color, and meanwhile, can be different from size according to its internal structure so that it is send
The light of different colours, shows after deliberation, and the size of quantum dot is the biggest more red territory, the least in deflection spectrum, is more partial to purple
Color, if so the quantum dot used is proper, then quantum dot just can send bright-coloured RGB light, is just used as display
RGB primary lights.
Quantum dot is the nano-scale particle that size is about 3 to 12 nanometers, and is monoenergetic level structure, and this just determines each
The frequency spectrum of the light that the quantum dot of fixed size sends after being stimulated is unique, i.e. color is unique, is pure color.So, I
Can pass through quantum spot size size, easily, accurately regulate its optical wavelength produced, and then produce different face
The light of color.
Summary of the invention
It is an object of the invention to obtain a kind of i.e. electrically conductive colored filter that can develop the color again.
First the application in the display of a kind of transparent conductive film is provided, transparent conductive film is applied to display
On colored filter.
Containing quantum dot in described transparent conductive film.
Described transparent conductive film is by being formed after colorful conductive pigment matrixing, and described colorful conductive pigment passes through
Quantum dot, nano-silver thread and organic solvent mix.
Forming black matrix" by BM line on the colored filter of described display, described colorful conductive pigment covers
BM line forms transparent conductive film.
Described colorful conductive pigment includes red conducting pigment, green conducting pigment and blue conducting pigment, described
Red conducting pigment, green conducting pigment and blue conducting pigment are repeated in arrangement by permanent order in black matrix".
The application in the display of a kind of nano-silver thread is additionally provided, nano-silver thread is applied to the colorized optical filtering of display
On sheet.
Described nano-silver thread is dissolved in organic solvent formation colorful conductive pigment together with quantum dot.
Described colorful conductive pigment ordered arrangement in the black matrix" of colored filter forms transparent conductive film.
Forming black matrix" by BM line on the colored filter of described display, described colorful conductive pigment covers
BM line forms transparent conductive film.
Described colorful conductive pigment includes red conducting pigment, green conducting pigment and blue conducting pigment, described
Red conducting pigment, green conducting pigment and blue conducting pigment are repeated in arrangement by permanent order in black matrix".
Colorful conductive pigment after blue light source excites just is provided with three kinds of colors of RGB, and the color of full wafer
Layer is connected together, because containing nano-silver thread in color layer, so can conduct electricity, this way, a step operation is the most permissible
Producing color layer and conductive layer, operation is simple.And because what quantum dot sent out is the light of pure color, so its brightness ratio is higher,
The optical filter colour gamut made is the most relatively wide；Furthermore, quantum dot than organic coating photoresistance more resistant to moisture, so life-span of product and can
Also to get well by property.
The present invention only uses one procedure to make one layer of colorful conductive layer, has color layer and transparency conducting layer simultaneously
Function, operation is simple, because the frequency spectrum of light that quantum dot is excited to send is unique, i.e. color is unique, is pure color；Gained
The colour gamut NTSC width of colorized optical filtering flake products, brightness height.
Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment.Unless stated otherwise, the present invention use reagent,
Equipment and method are the art conventional commercial reagent, equipment and conventional use of method.
Embodiment 1
A kind of colored filter, including conducting pigment, conducting pigment is by quantum dot, nano-silver thread and organic solvent mixing
Become.Organic solvent includes epoxy resin.Conducting pigment is divided into red conducting pigment, green conducting pigment and blue conducting pigment.
Quantum dot excites with blue light.Conducting pigment becomes matrix ordered arrangement on optical filter and is connected with each other.Matrix is that display is basic
On black matrix".Conducting pigment is divided into several to connect little lattice by BM line by black matrix", and conducting pigment fills little lattice, and accounts for
1/2 to the 2/3 of BM line.Red conducting pigment, green conducting pigment and blue conducting pigment are repeated in arrangement.Red conduction face
The difference of material, green conducting pigment and blue conducting pigment is to use various sizes of quantum dot.
Various sizes of nanoscale quantum dot is dissolved in and is prepared as conducting electricity with nano-silver thread solution organic solvent of arranging in pairs or groups
And RGB color can be produced with the pigment of red green and blue color on the substrate with BM figure with this by light source activation
Coloured picture shape, these color layers Overlay on BM line is the 1/2-2/3 of BM live width, and the color layer so made is connected the most mutually
Connecing, then UV solidifies and after temperature-curable, just can prepare colored filter with this color layer of light source activation.
The method one procedure of the present invention produces color layer and conductive layer, and technique is simple.
Embodiment 2
Nano-silver thread and quantum dot are all the materials of nano-scale particle, and they can be compatible to epoxy resin, so difference is received
Meter-sized quanta point material is dissolved in nano-silver thread, and is equipped with the organic solvents such as epoxy resin, initiator and firming agent, so that it may
To obtain the rubescent turquoise pigment of energy.
These pigment by with gluing, expose, the process developed on the figure substrate making BM, control color
Layer Overlay on BM line so that the color layer on its both sides interconnects.
First operation does red color layer, and its Overlay on BM line is the 1/2-2/3 of BM live width, follow-up work
Sequence green tint layer, blue color layer Overlay on BM line are the 1/2-2/3 of BM live width, then make on BM line
Two adjacent color layers be connected together the most mutually, the color layer of the most whole substrate all be interconnect, so ensure
The electric conductivity of entire substrate；Furthermore the color layer on BM line occupies the 1/2-2/3 of BM live width, color registration scope will not surpass
Go out the scope of BM live width, so not interfering with the colouristic properties of colored filter.
Then above-mentioned whole substrate after UV irradiates, then with the main solidification of temperature, it is therefore an objective to the moisture in pigment, have
The remaining nano-silver thread containing quantum dot of the removings such as machine gas or both mixture.
The quantum dot on substrate after said temperature being solidified with blue-light source or other light sources excites, because present amount
Son point material needs through light source activation, at present, market is main with blue light source excitation quantum point, so, this
Invention is preferably with blue light activated quantum dot.
Learning from the market, the current application process of quantum dot is to use molten night, makes the pigment that can expose, nanometer silver
Line thin film, has the characteristic of high-permeability and low-resistance value, can adjust the coefficient of viscosity of its solution and be coated making, institute
With this patent, the quantum dot of nano-scale particle is dissolved in solution organic solvent of arranging in pairs or groups, the mixing system of passing ratio of nano-silver thread
Standby one-tenth can send out the pigment of the conduction of different color, produces RGB color figure with this pigment on BM figure substrate, this
A little color layer Overlay on BM line are the 1/2-2/3 of BM live width, and the color layer so made just interconnects, then uses up
Source excitation quantum dot just can prepare colored filter.
The present invention uses nano-silver thread and the pigment of quantum dot mixing so that the color layer of preparation is electrically conductive, and such one
