The application of OLED in the head display field
The headwear display with video spectacles and portable cinema as an important carrier has been more and more widely used and developed. It has excellent advantages in the integration of digital video, virtual reality, virtual reality game, 3G and video glasses, and the integration of ultra portable multimedia devices and video glasses.
Compared with LCD and LCOS, OLED has great advantages in the application of head mounted display: clear and bright full color display, ultra-low power consumption and so on, which is a major driving force for the development of head mounted display.
The first application of OLED on video glasses is eMagin. in the US. It provides an excellent near eye application solution for civilian consumption, industrial applications and military applications. As a result, the European ultra OLED display video glasses were pushed into the market. In China, iTheater (AI Dai Dai) launched the world's first polymer super micro OLED display video spectacles with its strong R & D strength. With its intellectual property background, it successfully entered the domestic military field and made a contribution to the construction of Chinese digital soldiers.
The application of two and OLED in the field of MP3
MP3 as a digital walkman in the market have become the leading fashion and entertainment, for its function, capacity, price and so on have been widespread concern, is also the focus of attention of the manufacturers, but as for the eye of MP3 screen is seldom seen.
In addition to the audio and video products, most of the Flash or HDD MP3 are black and white LCD panels, and only stay in simple requests that can listen to music. But nowadays, MP3 is not only the most basic function, but also based on people's psychology of personality and fashion pursuit. It expresses a concept of life. So in the design of the panel, there is a colorful backlight design, which is often heard of "7 color backlight" products. On the basis of further development, has been useful to the regional color OLED panel (such as: yellow, blue and other areas of the 16 levels) products, representative BenQ Joybee180, iRiver N10 etc..
OLED（Organic Light Emitting Display），即有机发光显示屏，在MP3 屏幕的应用领域属于新崛起的种类，被誉为“梦幻显示屏”。它无需背光灯，而是“主动发光”。以BenQ Joybee180的OLED液晶屏为例，它摒弃了传统LCD的缺点，每个像素都可自行发光，不管在什么角度什么光线下都可以比传统LCD显示更加清晰的画面，而且环境越黑屏幕越亮，犹如夜间的莹彩精灵。
OLED (Organic Light Emitting Display), the organic light-emitting display, belongs to the new rising category in the application field of MP3 screen, and is known as the "dream display". It does not need a backlight, but "active light". OLED LCD screen BenQ Joybee180 as an example, it gets rid of the shortcomings of traditional LCD, each pixel can be self luminous, no matter what the point of what light can be compared with the traditional LCD display more clear picture, but the environment is black screen brighter, like the night elves yingcai.
MP3 consumers are mostly young people, for them MP3, in addition to basic functions, also has a little show of color. In the quiet street at night, walking and listening to music, watching the blue light of the OLED screen, the beating of the note, the beating of the feet and the ups and downs of the mood, there is a different feeling. Or on the Party of a friend's gathering, the Blu ray of OLED glittering and glittering can make you the main character of the party.
In addition to bringing new visual feelings, OLED has many advantages that the LCD panel can't compare. For example, it can make the MP3 lighter, thinner, more visible, and significantly save power. But the application of OLED also needs to be combined with the overall design of MP3 to show its charm. The BenQ Joybee180, which has been listed, can be said to be a model of the combination of the LCD screen application and the overall design. Joybee180 is fashionable, simple and generous, and the whole machine is square. It looks like a delicate handbag. The essence part is like a gorgeous watch. Moreover, using the fashionable elements of the watchband instead of the traditional way of wearing, it can provide a series of different panels, which can be replaced by the different clothes, changing the past invariable collocation schemes, showing your fashion collocation and showing your unique mood.
OLED applied to MP3 products not only increases the beauty of products, but also adds to the expression of graphic information, which will undoubtedly become the mainstream of MP3 display panels.
Three, potential applications
The main advantage of OLED technology is the active luminescence. The OLED of red, green and blue light can be obtained. Over the past few years, researchers have been working on the development of OLED applications from backlight, low - capacity displays to high - capacity displays. Next, the potential applications of OLED will be discussed and compared with other display technologies.
In 1999, the first commercialization of technology, technology is still very new. Used in some black and white / simple color car radios, mobile phones, handheld electric amusement devices, and so on. All belong to the high order machine.
从事OLED的商业开发全世界约 100多家厂商， OLED的技术发展方向分成两大类，日、韩和台湾倾向Kodak的低分子OLED技术，欧洲厂商则以PLED为主。两大集团中除了KODAK 联盟之外，另一个以高分子聚合物为主的飞利浦公司也联合了EPSON、DuPont、东芝等公司全力开发自己的产品。2007年第二季全球OLED市场的产值已达到1亿2340万美元。
There are about more than 100 businesses in the world engaged in the development of OLED. The direction of OLED technology development is divided into two categories. Japan, Korea and Taiwan tend to be low molecular Kodak OLED technology, while European manufacturers are mainly PLED. In addition to the KODAK alliance, the two largest group, another polymer company, is also a joint venture with EPSON, DuPont, Toshiba and other companies. PHILPS is developing its products. The output value of the global OLED market in the second quarter of 2007 has reached $123 million 400 thousand.
In Chinese enterprises, as early as in 2005, the Tsinghua University and visionox company decided to start a large-scale production line construction of OLED, and finally in Kunshan construction of a large-scale OLED production line; Guangdong province also actively launched OLED project, as of December 2009, Guangdong has been built, in the preparation and construction of the OLED production line 5, were significantly low polysilicon TFT technology Shanwei Xinli small size OLED production line, Foshan
