OELIt's EnglishOrganic electro-luminescentThe abbreviation of OLED, which means organic electroluminescence display technology (its light-emitting principle is very similar to the light-emitting principle of light-emitting diodes we are familiar with), this technology can only be used inPioneerIt can only be seen on the display panel of the car stereo.OELThe display screen uses an organic thin-film material. When an electric current passes through, the screen will glitter (this light is very weak, similar to the light emitted by some creatures in the deep sea). The display screen with this material can control each pixel independently. In addition, it can also be used to get a variety of different display colors Organic electroluminescence（EL）Device,Or organic light emitting diode（OLED）The general structure of the utility model is that an organic electroluminescent medium is sandwiched between a metal cathode and a transparent anode. After applying a certain voltage between electrodes,This light-emitting medium will emit light. takeOLEDApply to flat panel display,It has the advantages of active lighting, low power consumption, light weight, high efficiency and low production cost.OLEDDivided into small molecule organicELAnd polymer organicELTwo categories. Small molecule organicELOur research began withsixtyyears,But untileightyOnly in the early SKodakCorporateTangThe low driving voltage with practical value is developed for the first time（<10V）OrganicELDevices. stayone thousand nine hundred and eighty-sevenyear, KodakBefore the company announces its research results,This work did not attract people's attention. In the paper, TangAnd its collaborators have proved for the first time that new organic thin film materials can be used to produce organic films with high efficiency and brightnessELDevices.The device uses amorphous diamine film as hole transport layer,with8—Hydroxyquinoline aluminum（Alq）As a light-emitting layer. Less than10VUnder the voltage drive of,Got greater than100cd/m2Luminous brightness of,Its quantum efficiency (photon / electron) is about10%。 Please consult our business department for details
