OLED" >Present circumstance of technique and consuming the electronic industry and creating the trends of OLED
Step Science Technologies Co., Ltd. OLED initial " >Products manager of die set of camera of OLED peace machine The road is set up
The preface OLED " >OLED (organic luminescent diode),Also known as OEL (the organic electroluminescent device),Have spontaneous light, clear beautiful, light and thin, the intersection of speed of response and fast, the intersection of visual angle and wide, low energy consumption, operate the intersection of temperature range and old, low expense, make very simple technological procedure characteristic, been deemed to be the display unit favoured the most following LCD all the time since coming out, there are the markets of MP3 player, mobile telephone, auto display unit progressively at present. ISuppli Corporation statistics show, its industry scale was up to 251 million dollars, and grew up to 408 million dollars in 2004 in 2003 at the very same time, predict that will develop up to 615 million dollars this year. With OLED " >The improvement of OLED technology and batch productino with continuous capability, the faceplate typical price drops continuously, optimistic iS uppli thinks the camp charged still reachable 2,900 million dollars in 2011, it is 36% to compound the expanding up rate just about every year. It is observed that from improvement of merchandise, OLED " >OLED is in addition to smaller display field at present, jumbo size reveals the industry, for instance in the future: Notebook pc of the display unit, HDTV,etc. will all come to be OLED " >Goal application of OLED.
OLED" >OLED present circumstance of technique OLED " >OLED its basic structure is ITO (indium tin oxide) by the glass substrate Good pole, organic luminescent layer and negative pole make up. When the electron that the voltage injects into anodic electric cave and negative pole is in the organic luminescent layer accords with, stimulate the organic material but shiny. So far as driving signifies, divide it for the active (AM) And the passive form (PM),Because owners place one's back into and investigation and create in a big quantity in current years, the passive form OLED " >OLED has been obtained on topics such as life-span, chromophoric, electric consumption,etc. significantly to progress, OLED place out on the industry at present " >OLED merchandise are nearly all PMOLED " >OLED, but the technology of its procedure for preparing is still in creating. PMOLED" >The display of OLED can be divided into: The unicolor, area are polychromed and full-color. The area is polychr omed to show the body in the area of unicolor, match the display interval of other color. Full-color display technology is produced up of R.G.B. trichromatic repeated image element. Its technological emphasis point lies in color purity and efficiency of luminescent material, PMOLED at present " >OLED full-color display technology roughly divided into 3 original plain shiny law, colour filter law and 3 types of technology of color transfer approach independently. 3 types of PMOLED " >OLED is full-color to reveal technical comparison is shown in Table 1. The table 1 PMOLED " >OLED just about every full-color the intersection of display technology and comparative the intersection of project and 3 element shiny the intersection of law and the intersection of colour filter and the intersection of law and the intersection of color and the intersection of transfer approach and the intersection of luminescent layer and form separate serial the intersection of membrane and serial the intersection of membrane and group independently Board low expense cocoa apparatus with high costs obtaining reduce incredibly for finishing apt and tough in Chengs yellow's is patent tough in procedure for preparing in deposition obtaining decent and decent in contrast additional degree in differences decent to exchange patent luminescent efficiency for but definition PMOLEs goods obtaining much better incredibly D" >The crucial technological crucial to OLED is in the luminescent material, capsulate and drive, the technological bottleneck induced given that of 3 crucial element procedure for preparing at present is as follows, luminescent efficiency insufficient and R.G.B inconsistent in the intersection of material and shiny life-span and batch productino technology unripe and jumbo size tough driving IC have, seek unity of normal. AMOLED" >OLED crucial structure is the electric-present driving, by the luminescent display of stable present control, use steady voltage cont rol to be shiny and various with TFT-LCD, AMOLED " >OLED is in order to reach the sufficient luminance, somewhat needs TFT of energy-handling capability flows in the heavy currents, high low-temperature polycrystalline silicon thin-film transistor (LTPS TFT) of the electronic flowrate Turn into AMOLED " >The key driving source of OLED, make LTPS technology come to be and create AMOLED " >One of the technology that OLED should possess. According to present statistics, 2005 big-frame AMOLED " >OLED faceplate will begin to mobilize in an all-round way, will nearly have 15 key AMOLEDs " >OLED faceplate production line, since the entering quantity childbirth period in Japan, South Korea, our country Taiwan and display unit manufacturer of Hong Kong area, amongst them 9 production lines are Japan, the manufacturer which includes SKD (Sanyo enters into partnership with Kodak), TMD (Toshiba enters into partnership with Panasonic), Hitachi, Northeastern pioneer, ST-LCD ( The automati c loom of Sony and Toyota enters into partnership), porcelain of Beijing reveals and wise worker Epson,etc..

OLED in the mobile telephone " >OLED is mostly implemented as pair and rejected, primarily polychromed and full-color as the key truth with the area of the definition 96*64. Create the application of various merchandise with manufacturer's efforts, the application of other fields is promoted progressively. Add OLED " >OLED will enter batch productino this year, thereupon increasing too in the application proportion of the base display unit of the mobile telephone, MP3 manufacturer directs against the big-frame OLED too " >OLED staging personal merchandise, set about researching and creating the player merchandise of private media. According to state of improvement of the industry at present, the industry of mobile telephone of this year will catch up with and surpass industry of MP3 player progressively. OLED" >Size and life-span of OLED can entirely currently meet mobile phone's demands, can locate out OLED from Table 2 " >OLED reveal, super ior to, reveal product though being other too at the characteristic. Light and thin respect, thickness its, commonly inside 2mm, weight in 3 gram about commonly. Ordinary pairs of color folding mobile phones, commonly tends to make an appointment in four.5-5.0mm for the thickness. And if pair rejects and adopts OLED " >OLED commonly tends to make an appointment in 3.5-four.5mm, if the main-secondary rejects and adopts OLED " >Of OLED can understand 3.5-four.0mm is hence constructional style additional imagination spaces. It is reported present ultrathin MP3 player and mobile telephone adopt OLED " >OLED. Reveal the respect, possess the intelligent mobile telephone in functions such as the high image element taking pictures, creating a video recording, flow media broadcasting, game,etc., want to understand the high clarity, low energy consumption, smooth image. The entire planet adopts OLED at present " >100 varied mobile phones of OLED, it is nearly all this kind of merchand ise. In price, a single that is with definition 128*128,262ks are 1.5 inches of colored as the example, PMOLED " >OLED is less costly by about 1 dollar even than siTFT-LCD. From OLED " >Technology and the intersection of industry and improvement of OLED come, watch, currently from unicolor and area polychromed to promote to be full-color progressively, currently a great deal of factories have discussed and created AMOLED at the very same time" >OLED, so can predict future OLED " >OLED can from present the intersection of mobile telephone and vice display unit, the intersection of MP3 and application of player in product industry, expand it to the display unit of additional consumption electronic merchandise though coming progressively.
