Abstract
The present invention relates to a full colour polar biased electric excited luminous element and a manufacturing method. Main steps of the method comprise: cleaning and patterning a base board; setting a transparent conducting layer to the base board; evaporating and coating an orientated small molecule matching layer at the specific temperature of the base board; evaporating and coating a small molecule luminous layer again; setting an electronic transmission layer; finally, setting a cathode layer and sealing the luminous element. When the small molecule luminous layer is arranged on the surface of the small molecule matching layer, arrangement in the specific direction can be formed along the crystal lattice direction by the specific crystal lattice direction of the surface of the small molecule matching layer by the small molecule matching layer having directivity, and then, polar biased light in the specific direction can be obtained. Thus, when a polar biased plate is used, the use rate of the light source energy of the luminous element can be increased.
Description
Technical field
The present invention is a kind of full-color polarization electroluminescence element, can be applicable to industries such as organic electro-luminescent display, three-dimensional film display, and a high efficiency polarization light source is provided.
Background technology
General polarization image all is to utilize Polarizer to absorb the polarised light of a direction of image, and to obtain linear polar biased light, the result because of Polarizer absorbs makes its energy utilization efficiency not high, and the highest also only have 50%.
For example very popular in recent years three-dimensional film, the mode of its demonstration is to utilize two displays to throw different polarization light show images simultaneously in screen, the special spectacles that has different polaroids about utilizing spectators again and being worn, experience stereopsis, yet by after the polaroid, its energy is absorbed in a large number.
The light emitting source of display, its material is divided into and uses two kinds of inorganic compound and fluorescent organic compounds, use the backlight of inorganic compound to comprise brilliant formula of heap of stone or thick pattern, the fluorescent organic compound then roughly is divided into micromolecule electroluminescence element (OLED) and macromolecule electroluminescence element (PLED) according to its molecular weight.
The principle of luminosity of organic electroluminescent element is to utilize properties of materials, with electron hole combination on luminescent layer, and electronics is fallen back ground state by the form of excitation state, and unnecessary energy is disengaged with the form of ripple, thereby reach the generation of the light-emitting component that different wave length is arranged.Wherein anode (Anode) is tin indium oxide (ITO) electro-conductive glass film, with sputter or evaporation mode, be attached on glass or the transparent plastic substrate, negative electrode then contains magnesium (Mg), aluminium (Al), lithium metals such as (Li), then be the light-emitting zone that a plurality of organic films form between two electrodes, comprise injection region, hole (Hole injection layer; HIL) hole-transfer district (HoleTransport Layer; HTL) organic luminous layer (Emitting layer) and electron transfer layer (Electron Transport Layer; ETL), when practical application is produced in batches, consider, also can comprise other different films sometimes based on different demands.
Because organic molecule electroluminescence material can not tempering, so can't be in the mode of rubbing or stretching, make the luminescent layer molecules align have directivity, wish to get the light source of polarization, normally utilize a Polarizer to absorb the polarised light of a direction of image, obtaining a linear polar biased optical image, so the utilization ratio of its energy of light source is not high, and usually usury efficient is 50%.
Summary of the invention
Main purpose of the present invention is to solve above-mentioned defective, for fear of the existence of defective, the invention provides a high efficiency polarization light source.The present invention utilizes directed micromolecular evaporation coating technique, in the micromolecule both alignment layers that has directivity under room temperature or the particular substrate temperature with special angle oblique evaporation one deck on tin indium oxide (ITO) electrically-conductive backing plate, distinguish evaporation red (R), green (G), blue (B) three look micromolecule luminescent materials on this micromolecule both alignment layers with the light shield technology again, one cathode layer and encapsulation are set at last again, promptly get a light-emitting component that can send linear polarization light.
The invention provides a kind of full-color polarization electroluminescence element, include: a transparency carrier (10); One is positioned at the transparency conducting layer (20) on the aforesaid substrate; One is positioned at the micromolecule both alignment layers (30) of above-mentioned transparency conducting layer (20); One is positioned at the micromolecule luminescent layer (40) on the above-mentioned micromolecule both alignment layers (30); One is positioned at the electron transfer layer (50) on the above-mentioned micromolecule luminescent layer (40); One is positioned at the cathode layer (60) on the above-mentioned electron transfer layer (50); Wherein,, above-mentioned micromolecule luminescent layer is arranged according to the lattice direction of both alignment layers, thereby obtained sending out the electroluminescence element of polar biased light by oblique evaporation micromolecule luminescent layer.
