The OLED oled modules of origin

The history of the OLED power than inorganic materials EL (LED) to be late. In 1936, Destriau organic fluorescent compound dispersed in the polymer film made, obtained the earliest electroluminescent device. 1950s people started organic material electrically organic light emitting device Exploration A.Bernanose of people on both sides of the anthracene single chip with 400V DC voltage to the light emitting phenomenon was observed, due to the thick single crystal of 10mm to 20mm, so The driving voltage is higher. The 1963 M.Pope anthracene single crystal electroluminescent. Deng Qingyun Kodak Company in 1987 for the first time developed a low driving voltage (<10V> 1000cd/m2) the OLED Devices (Alq3 as a light-emitting layer) has practical value. In 1990, the University of Cambridge, UK Burroughes and his collaborators successful first polymer organic electroluminescent devices (PLED) (PPV as the light-emitting layer), more practical organic electroluminescent display device further laid the foundation The the annual Forrest Task Force doped heavy metal compounds electrophosphorescence and triplet exciton excited states of the electric EL internal quantum efficiency is greatly improved.OLED Module
At present, the world has more than 100 research institutions and enterprises into the development and production of OLED display currently on the market giant. Generally speaking, the OLED industrialization has begun, monochrome, multicolor and color devices has reached the level of mass production, there are still difficulties in large-size full-color production-ready device.TFT Display Module
